Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rehabilitation training, in particular to a training device for upper limb rehabilitation. BACKGROUND

[0002] The upper limb rehabilitation training device is designed for patients with upper limb dysfunction (such as stroke, cerebral palsy, trauma, etc.), aiming to help patients recover the motor function of the upper limbs through physical therapy or mechanical assistance.

[0003] The existing upper limb rehabilitation training device is prone to shaking when the upper limbs are stretched along the length direction of the training table, reducing the training effect. SUMMARY

[0004] Therefore, it is necessary to provide a training device for upper limb rehabilitation to solve the technical problem that the existing upper limb rehabilitation training device is prone to shaking when the upper limbs are stretched along the length direction of the training table, reducing the training effect.

[0005] To achieve the above purpose, the present application provides a training device for upper limb rehabilitation, comprising:

[0006] The training table is provided with a through hole on one side, and a training mechanism is installed on the other side of the training table. The training mechanism includes a training assembly and a guide assembly. The training assembly includes a mounting bracket, two pulley pieces, a pull rope, two arc-shaped plates, and two handles. The mounting bracket is installed on the training table. The two pulley pieces are installed on the mounting bracket along the width direction of the training table. The pull rope is arranged outside the two pulley pieces, and the two ends are parallel to the length direction of the training table. The two arc-shaped plates are installed at the two ends of the pull rope, respectively. The two handles are installed on the two arc-shaped plates, respectively. The guide assembly includes a guide rail and a guide block. The guide rail is parallel to the length direction of the training table. The top of the guide block is connected to the bottom of the arc-shaped plate. The bottom of the guide block slides on the guide rail. The arc-shaped plate moves along the length direction of the training table towards or away from the through hole on the guide rail.

[0007] The seat is installed at the through hole and faces the training mechanism.

[0008] Unlike the prior art, the technical solution of the present application provides a training table specially used for upper limb training. The user can sit on the seat to practice the upper limbs, which is more comfortable. At the same time, a special guide assembly is provided to allow the user to move along the length direction of the training table during upper limb movement, which is more stable and less likely to shake, thereby achieving better training effect.

[0009] Preferably, the training mechanism further includes a pulley adjustment assembly, which includes a bidirectional threaded screw and a first motor. The bidirectional threaded screw is installed in the mounting frame along the width direction of the training table. Two pulleys are threadedly connected to the bidirectional threaded screw. The first motor is installed at one end of the mounting frame, and the output end of the first motor is connected to the bidirectional threaded screw.

[0010] In this way, by setting up a pulley adjustment component, the distance between the two pulleys can be adjusted according to the shoulder width of different users, thus making it convenient for different users to use.

[0011] Preferably, there are two or more guide rails spaced apart along the width of the training table, and the bottom of the guide block is detachably connected to the two or more guide rails.

[0012] In this way, by setting multiple guide rails and detachable guide blocks, it is ensured that when the distance between two pulleys changes, the position of the rope along the width of the training table can also change accordingly, thereby ensuring that the direction of the rope's tension is tangent to the rotation direction of the corresponding pulley, so as to ensure the transmission of force.

[0013] Preferably, the training mechanism also includes two sets of grip strength components, which are mounted on two curved plates to train the user's hand grip strength.

[0014] In this way, by setting up grip strength components, in addition to training the user's upper limbs, the user's hands can also be trained, thus improving the training effect.

[0015] Preferably, the grip force assembly includes a first fixing frame, a second fixing frame, a grip force adjusting bolt, a sliding column, a sliding sleeve, a first elastic element, a connecting frame, two first grip force bars, and two hinges;

[0016] The first fixed frame is installed at both ends of the arc-shaped plate. The second fixed frame is installed on the top of the first fixed frame. A grip adjustment bolt is rotatably connected inside the second fixed frame. The bottom of the grip adjustment bolt is threadedly connected to the sliding column. The sliding column is located inside the second fixed frame. A sliding sleeve is fitted outside the sliding column and is located inside both the first and second fixed frames. The sliding sleeve slides with the first fixed frame and the sliding column respectively. A first elastic element is installed inside the sliding sleeve. The bottom of the first elastic element is connected to the bottom inside the sliding sleeve. The top of the first elastic element is connected to the top of the sliding column. A connecting frame is installed on the arc-shaped plate. The two first grip bars are connected by the connecting frame and slide along the width of the training table on the connecting frame. Two hinges correspond to the two first grip bars respectively. One end of the hinge is hinged to the first grip bar, and the other end of the hinge is hinged to the sliding sleeve.

[0017] In this way, by setting up the grip strength adjustment bolt, the sliding column and the first elastic element, the resistance of the first elastic element can be adjusted, thereby adjusting the intensity of the user's hand training, effectively improving the adaptability and flexibility of the grip strength component.

[0018] Preferably, the training mechanism also includes a rope adjustment component, which is installed on the training table and located between two pulley components. The rope is wound around the rope adjustment component, and the rope adjustment component adjusts the length of the rope.

[0019] Thus, by setting up a rope adjustment component, the length of the pull rope can be adjusted to suit the upper limb length of different users, making it more flexible to use.

[0020] Preferably, the rope adjustment assembly includes an adjustment screw, an adjustment rod, and a second motor. The adjustment screw extends along the length of the training table and is installed inside the training table. The adjustment rod is threadedly connected to the adjustment screw. The pull rope is wound around the adjustment rod. The second motor is installed inside the training table, and its output end is connected to the adjustment screw.

[0021] In this way, by adjusting the lead screw, adjusting rod, and second motor, the length of the pull rope can be controlled more intelligently, and the adjustment is more convenient.

[0022] Preferably, the training component also includes two fixing seats, which are respectively fitted onto both ends of the pull rope and slidably connected to the pull rope. The bottom of the fixing seats can be detachably installed on the top of the training table.

[0023] Thus, by setting a fixed base, the two ends of the pull rope can be parallel to the length direction of the training table. In conjunction with the guide component, it can further guide the user's upper limbs to move along the length direction of the training table.

[0024] Preferably, the training component also includes two fixing straps, which are respectively mounted on two curved plates and used to fix the user's wrist.

[0025] In this way, by setting a fixing strap, the user's wrist can be fixed, the user's hand can be firmly fixed, and the user's arm can be prevented from falling off the curved board during upper limb training, which would affect the training.

[0026] Preferably, the training device for upper limb rehabilitation also includes a seat adjustment mechanism, which is installed on the seat and adjusts the height and / or width and / or tilt angle of the seat.

[0027] Thus, by setting up a seat adjustment mechanism, the height and / or width and / or tilt angle of the seat can be adjusted, thereby allowing the seat to be adjusted according to the height of different users, meeting the usage needs of different users, and improving the comfort of users during training.

[0055] For ease of explanation, the length, width, and height of the training table are defined, with each pair of directions perpendicular to the others. For clarity, as shown below... Figures 1 to 4 , Figure 7 , Figure 8 and Figure 12 As shown by the arrows, the direction of arrow X is the width direction of the training table, the direction of arrow Y is the length direction of the training table, and the direction of arrow Z is the height direction of the training table.

[0056] According to some embodiments of this application, please refer to Figures 1 to 13 This invention provides a training device for upper limb rehabilitation, including a training table 1 and a seat 2. A through hole 11 is provided on one side of the training table 1, and a training mechanism 12 is installed on the other side of the training table 1. The training mechanism 12 includes a training component 121 and a guide component 122. The training component 121 includes a mounting frame 1211, two pulleys 1212, a pull rope 1213, two arc-shaped plates 1214, and two handles 1215. The mounting frame 1211 is mounted on the training table 1. The two pulleys 1212 are spaced apart on the mounting frame 1211 along the width direction X of the training table. The pull ropes 1213 are disposed outside the two pulleys 1212, and the two... The end is parallel to the length direction Y of the training table. Two arc-shaped plates 1214 are respectively installed at both ends of the pull rope 1213, and two handles 1215 are respectively installed on the two arc-shaped plates 1214. The guide assembly 122 includes a guide slide rail 1221 and a guide block 1222. The guide slide rail 1221 is parallel to the length direction Y of the training table. The top of the guide block 1222 is connected to the bottom of the arc-shaped plate 1214. The bottom of the guide block 1222 slides on the guide slide rail 1221. The arc-shaped plate 1214 moves closer to or further away from the through hole 11 along the length direction Y of the training table on the guide slide rail 1221. The seat 2 is installed at the through hole 11 and faces the training mechanism 12.

[0057] Training table 1 is an existing table with supporting legs. Optionally, lockable casters are provided at the bottom of the supporting legs of training table 1 to facilitate moving training table 1 and fixing it after it is moved to a designated position. The lockable casters are existing casters, so they will not be described in detail. A through hole 11 is provided on one side of the tabletop of training table 1. The through hole 11 can be U-shaped and the transition edge is rounded to prevent users from bumping into it when entering.

[0058] The pulley assembly 1212 includes a skateboard 1219 and a pulley 1218. The skateboard 1219 is mounted on the mounting bracket 1211. The pulley 1218 is rotatably connected inside the skateboard 1219. A pull rope 1213 is provided outside the pulley 1218. Both ends of the pull rope 1213 are fixedly connected to curved plates 1214. The curvature of the curved plates 1214 can well fit the user's hand, making the user's hand placement more comfortable. A handle 1215 is provided on the curved plate 1214 for the user to hold, making it convenient for the user to hold the handle 1215 for upper limb training.

[0059] The guide rail 1221 can be an existing linear guide rail. The guide rail 1221 is connected to the bottom of the curved plate 1214 via a guide block 1222, and the guide block 1222 slides on the guide rail 1221. When the user performs upper limb training, the curved plate 1214 slides on the guide rail 1221 via the guide block 1222, thereby allowing the upper limb to move closer to or further away from the through hole 11 along the length Y of the training table, making it more stable.

[0060] The seat 2 can be a regular backrest seat 2. The seat 2 can be placed directly at the through hole 11, or its top can be connected to the training table 1. The seat 2 faces the training mechanism 12, that is, the back of the seat 2 faces the training mechanism 12, so that when the user sits on the seat 2, the user faces the training mechanism 12, and the hands can be placed in the corresponding curved plate 1214 for training.

[0061] The technical solution of this application includes a training table 1 specifically designed for upper limb training, allowing users to sit comfortably on a chair 2 to practice their upper limb exercises. Simultaneously, a dedicated guide component 122 allows users to move along the length Y direction of the training table during upper limb exercises, reducing wobbling and ensuring more stable movement, thereby achieving better training results.

[0062] like Figure 7As shown, the training mechanism 12 also includes a pulley adjustment assembly 123. The pulley adjustment assembly 123 includes a bidirectional threaded screw 1231 and a first motor 1232. The bidirectional threaded screw 1231 is installed in the mounting frame 1211 along the width direction X of the training table. Two pulleys 1212 are threadedly connected to the bidirectional threaded screw 1231. The first motor 1232 is installed at one end of the mounting frame 1211, and the output end of the first motor 1232 is connected to the bidirectional threaded screw 1231.

[0063] The pulley adjustment assembly 123 also includes a limiting rod, which is installed within the mounting bracket 1211 along the width direction X of the training table. The limiting rod is used to restrict the pulley component 1212 from rotating with the bidirectional threaded screw 1231. A first motor 1232 can be mounted on one end of the mounting bracket 1211 via a motor bracket. Under the action of the first motor 1232, the two pulley components 1212 move towards or away from each other on the bidirectional threaded screw 1231. In some embodiments, such as... Figure 8 As shown, the pulley adjustment assembly 123 also includes two hydraulic rods 1233, the output end of each hydraulic rod 1233 being connected to a pulley component 1212. The pulley component 1212 slides on the mounting base, and the hydraulic rods 1233 can individually drive the corresponding pulley component 1212 to move along the width direction X of the training table, thereby adjusting the position of the two pulley components 1212. In other embodiments, the position of the two pulley components 1212 can also be adjusted by means of a pulley 1218 adjusting bolt threadedly connected to the pulley component 1212.

[0064] Thus, by setting the pulley adjustment component 123, the distance between the two pulley components 1212 can be adjusted according to the shoulder width of different users, thereby making it convenient for different users to use.

[0065] like Figure 4 As shown, there are two or more guide rails 1221 spaced at intervals along the width direction X of the training table, and the bottom of the guide block 1222 is detachably connected to the two or more guide rails 1221.

[0066] The bottom of the guide block 1222 can be detachably connected to the guide rail 1221 via magnetic attraction or fasteners. Taking magnetic attraction as an example, a strong magnet is provided at the bottom of the guide block 1222, and corresponding metal blocks or magnets are provided at corresponding positions on multiple guide rails 1221. Figure 4As shown, in this embodiment, four guide rails 1221 are provided. In other embodiments, the number and distance of the guide rails 1221 can be adjusted according to the position of the two pulley components 1212 by adjusting the pulley adjustment assembly 123. Optionally, the pulley adjustment assembly 123 also includes a measuring ruler, which is mounted on the mounting bracket 1211. The position of the two pulley components 1212 can be determined according to the measuring ruler, thereby facilitating the determination of the position of the two arc-shaped plates 1214, so that the bottom of the guide block 1222 is connected to the guide rail 1221 at the corresponding position.

[0067] Thus, by setting multiple guide rails 1221 and detachably connected guide blocks 1222, it is ensured that when the distance between two pulley components 1212 changes, the position of the pull rope 1213 along the width direction X of the training table can also change accordingly, thereby ensuring that the direction of the pull force of the pull rope 1213 is tangent to the rotation direction of the corresponding pulley component 1212, so as to ensure the transmission of force.

[0068] like Figure 6 , Figures 9 to 11 As shown, the training mechanism 12 also includes two sets of grip strength components 124, which are mounted on two curved plates 1214. The grip strength components 124 train the user's hand grip strength.

[0069] Thus, by setting up the grip strength component 124, in addition to training the user's upper limbs, the user's hands can also be trained, thereby improving the training effect.

[0070] like Figure 6 and Figure 9As shown, the grip strength assembly 124 includes a first fixed frame 1241, a second fixed frame 1242, a grip strength adjusting bolt 1243, a sliding column 1244, a sliding sleeve 1245, a first elastic element 1246, a connecting frame 1247, two first grip strength rods 1248, and two hinges 1249. The two ends of the first fixed frame 1241 are mounted on the two ends of the arc-shaped plate 1214. The second fixed frame 1242 is mounted on the top of the first fixed frame 1241. The grip strength adjusting bolt 1243 is rotatably connected inside the second fixed frame 1242. The bottom of the grip strength adjusting bolt 1243 is threadedly connected to the sliding column 1244. The sliding column 1244 is located inside the second fixed frame 1242. The sliding sleeve 1245 is sleeved outside the sliding column 1244 and located above the first fixed frame 1241. Within the second fixed frame 1242, the sliding sleeve 1245 slides with the first fixed frame 1241 and the sliding column 1244 respectively. The first elastic element 1246 is installed inside the sliding sleeve 1245. The bottom of the first elastic element 1246 is connected to the bottom inside the sliding sleeve 1245, and the top of the first elastic element 1246 is connected to the top of the sliding column 1244. The connecting frame 1247 is installed on the arc plate 1214. The two first gripping bars 1248 are connected by the connecting frame 1247 and slide along the width direction X of the training table on the connecting frame 1247. The two hinges 1249 correspond to the two first gripping bars 1248 respectively. One end of the hinge 1249 is hinged to the first gripping bar 1248, and the other end of the hinge 1249 is hinged to the sliding sleeve 1245.

[0071] The first elastic element 1246 is elastic, can elastically contract when subjected to pressure, and can return to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber and silicone.

[0072] The sliding sleeve 1245 slides along the height direction Z of the training table, respectively, with the first fixed frame 1241 and the sliding column 1244. The bottom of the connecting frame 1247 is mounted on the arc-shaped plate 1214, and a first gripping bar 1248 is mounted at each end of the connecting frame 1247. The first gripping bar 1248 slides along the width direction X of the training table at both ends of the connecting frame 1247. Preferably, the outer surface of the first gripping bar 1248 is provided with anti-slip patterns to facilitate gripping by the user.

[0073] During actual hand training, when the user grips the first gripping bar 1248, it slides along the width X of the training table outside the connecting frame 1247, and pushes the sliding sleeve 1245 upward through the external hinge 1249, providing resistance to the hand through the first elastic element 1246. When the hand is released, the first elastic element 1246 returns to its original shape, releasing the stored energy and providing a certain reaction force, and the first gripping bar 1248 returns to its original shape. Repeatedly gripping and releasing the first gripping bar 1248 can achieve hand training, improving the training effect on the user's upper limbs. When it is necessary to adjust the training intensity of the first gripping bar 1248, the grip strength adjustment bolt 1243 can be rotated, causing the grip strength adjustment bolt 1243 to drive the sliding column 1244 to slide up or down along the height Z of the training table through the threaded connection, thereby adjusting the elasticity of the first elastic element 1246.

[0074] Thus, by setting up the grip strength adjustment bolt 1243, the sliding column 1244 and the first elastic element 1246 in combination, the resistance of the first elastic element 1246 can be adjusted, thereby adjusting the intensity of the user's hand training and effectively improving the adaptability and flexibility of the grip strength component 124.

[0075] like Figure 10 As shown, the grip strength assembly 124 also includes two second grip strength bars 1251 and a second elastic element 1252. The bottoms of the two second grip strength bars 1251 slide along the width direction X of the training table on the arc plate 1214, and the two second grip strength bars 1251 are connected by the second elastic element 1252.

[0076] A second slide rail extending along the width direction X of the training table can be provided on the curved plate 1214, and the bottoms of the two second gripping bars 1251 slide on the second slide rail. The second elastic element 1252 is elastic, capable of elastically contracting under pressure and returning to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber or silicone. Preferably, the outer surface of the second gripping bar 1251 is provided with anti-slip patterns to facilitate gripping by the user.

[0077] Thus, hand training can be achieved simply by using the second gripping bar 1251 and the second elastic element 1252, resulting in a simple structure.

[0078] like Figure 11 As shown, the grip strength assembly 124 also includes two third grip strength bars 1253 and two third elastic members 1254. The bottoms of the two third grip strength bars 1253 slide along the width direction X of the training table on the arc plate 1214. The two third grip strength bars 1253 are connected by two third elastic members 1254, and the two third elastic members 1254 are set at an angle.

[0079] A third slide rail extending along the width direction X of the training table can be provided on the curved plate 1214, and the bottoms of the two third gripping bars 1253 slide on the third slide rail. The third elastic element 1254 is elastic, capable of elastically contracting under pressure and returning to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber or silicone. Preferably, the outer surface of the third gripping bar 1253 is provided with anti-slip patterns to facilitate gripping by the user.

[0080] Thus, on the one hand, the inclined design of the third elastic element 1254 provides non-linear resistance, meaning that the resistance gradually increases as the third gripping bar 1253 moves, resulting in a better training effect. On the other hand, the inclined design of the two third elastic elements 1254 forms a V-shaped structure, which coordinates the tension of the third elastic elements 1254 when gripped, providing more balanced resistance and avoiding unilateral overload. Furthermore, the inclined design of the third elastic element 1254 can absorb forces from different directions, reducing hand fatigue.

[0081] like Figure 12 and Figure 13 As shown, the training mechanism 12 also includes a rope adjustment assembly 126, which is installed on the training table 1 and located between two pulleys 1212. The pull rope 1213 is wound around the rope adjustment assembly 126, and the rope adjustment assembly 126 adjusts the length of the pull rope 1213.

[0082] Thus, by setting the rope adjustment component 126, the length of the pull rope 1213 can be adjusted to suit the length of different users' upper limbs, making it more flexible to use.

[0083] like Figure 12 As shown, the rope adjustment assembly 126 includes an adjustment screw 1261, an adjustment rod 1262, and a second motor 1263. The adjustment screw 1261 extends along the length Y direction of the training table and is installed inside the training table 1. The adjustment rod 1262 is threadedly connected to the adjustment screw 1261. The pull rope 1213 is wound around the adjustment rod 1262. The second motor 1263 is installed inside the training table 1, and its output end is connected to the adjustment screw 1261.

[0084] Two grooves are provided on the surface of the training table 1, and the adjusting screw 1261 and the second motor 1263 are respectively installed in the two grooves, which is more aesthetically pleasing. In addition, the grooves can also limit the rotation of the adjusting rod 1262 with the adjusting screw 1261.

[0085] When the rope adjustment assembly 126 is actually adjusted, the second motor 1263 drives the adjustment screw 1261 to rotate. The adjustment screw 1261 then drives the external adjustment rod 1262 to slide along the length Y direction of the training table through a threaded connection. The adjustment rod 1262 can then stretch the pull rope 1213, thereby adjusting the extension length of the pull rope 1213 to accommodate the arm length of different users.

[0086] In this way, by adjusting the lead screw 1261, the adjusting rod 1262 and the second motor 1263, the length of the pull rope 1213 can be controlled more intelligently, and the adjustment is more convenient.

[0087] like Figure 13 As shown, the rope adjustment assembly 126 also includes a rope adjustment bolt 1264. The bottom of the rope adjustment bolt 1264 is rotatably connected to the desktop of the training table 1. The rope adjustment bolt 1264 has external threads, and the pull rope 1213 is wound around the rope adjustment bolt 1264. Thus, the number of turns of the pull rope 1213 can be controlled by manually rotating the rope adjustment bolt 1264, thereby adjusting the extension length at both ends of the pull rope 1213, resulting in a simpler structure. In some embodiments, the rope adjustment assembly 126 also includes a rotation motor 1265. The rotation motor 1265 is mounted on the desktop of the training table 1, and its output end is connected to the bottom of the rope adjustment bolt 1264. The rotation of the rope adjustment bolt 1264 is controlled by the rotation motor 1265, making it more intelligent and convenient.

[0088] In some embodiments, the first motor 1232, the second motor 1263, and the rotary motor 1265 are all communicatively connected to an external controller. This makes control via the external controller more intelligent and convenient. Optionally, the external controller can be mounted on the training table 1 for easy access and operation.

[0089] like Figure 2 As shown, the training component 121 also includes two fixing seats 1216, which are respectively sleeved on both ends of the pull rope 1213 and slidably connected to the pull rope 1213. The bottom of the fixing seat 1216 is detachably installed on the top of the training table 1.

[0090] The fixing base 1216 can be inverted V-shaped or inverted A-shaped, with a triangular structure providing greater stability. The bottom of the fixing base 1216 can be detachably installed on the top of the training table 1 via tenon and mortise or snap-fit. The fixing base 1216 needs to change position with the curved plate 1214 to ensure that the direction of the tension of the pull rope 1213 is tangent to the rotation direction of the corresponding pulley 1212.

[0091] Thus, by setting the fixed seat 1216, the two ends of the pull rope 1213 can be parallel to the length direction Y of the training table. In conjunction with the guide component 122, it can further guide the user's upper limbs to move along the length direction Y of the training table.

[0092] like Figure 6 As shown, the training component 121 also includes two fixing straps 1217, which are respectively mounted on two curved plates 1214 and fix the user's wrist.

[0093] The restraint strap 1217 can be an elastic band, a strap with Velcro at both ends, or a handcuff, etc., used to secure the user's wrist.

[0094] Thus, by setting the fixing strap 1217, the user's wrist can be fixed, the user's hand can be firmly fixed, and the user's hand can be prevented from falling off the curved plate 1214 during upper limb training, which would affect the training.

[0095] In some embodiments, the training device for upper limb rehabilitation further includes a seat adjustment mechanism, which is mounted on the seat 2 and adjusts the height and / or width and / or tilt angle of the seat 2.

[0096] The seat adjustment mechanism is existing technology and will not be described further. The seat adjustment mechanism can adjust the height and / or width and / or tilt angle of the seat 2.

[0097] Thus, by setting up a seat adjustment mechanism, the height and / or width and / or tilt angle of seat 2 can be adjusted, thereby allowing seat 2 to be adjusted according to the height of different users, meeting the usage needs of different users, and improving the comfort of users during training.

[0098] The working principle of a training device for upper limb rehabilitation is as follows:

[0099] The user enters through hole 11 and sits on seat 2. After adjusting seat 2 to a suitable position using the seat adjustment mechanism, the positions of the two pulleys 1212, the guide component 122, and the length of the pull rope 1213 can be adjusted according to usage needs. After adjustment, the user places both hands on the two curved plates 1214 and holds the grip strength bar, then secures the wrists with the fixing strap 1217. Then, the user can perform upper limb rehabilitation training by pulling back and forth with both arms. During this process, the two pulleys 1212 act as a transition, and the guide component 122 helps the upper limbs maintain movement along the Y-direction of the training table, preventing wobbling. While performing upper limb training, the user can also use the grip strength component 124 to train hand grip strength.
