Description

Technical Field

[0001] This invention relates to a method for evaluating rehabilitation effectiveness, and more particularly to a method that allows users to conduct rehabilitation at home and then provide the data obtained to medical institutions for remote rehabilitation effectiveness evaluation. Prior Technology

[0002] Currently, people with foot injuries, mobility impairments, or those requiring rehabilitation typically use a four-legged cane or walking aid for support and assistance.

[0003] To help users better understand how to rehabilitate, some assistive devices already provide rehabilitation guidance functions. For example, Republic of China Patent Publication No. I565462 discloses a rehabilitation guidance mobility aid, which includes a main body, a processing unit, a guidance module, a detection module, an inertial sensing unit, a recording module, and a power module.

[0004] The aforementioned patent also provides a rehabilitation guidance method for a mobility aid, comprising: A. A mobility aid constantly emitting a visible light toward the landing point of each step; B. Guided by the visible light, moving the mobility aid to the landing point; C. The mobility aid constantly emitting an ultrasonic wave toward the landing point of at least one foot at each step, forming a detection area; D. Detecting whether at least one foot has moved into the detection area; E. Recording the movement process of any of the above steps and notifying a remote device; F. Detecting any step, and issuing a warning message if an abnormality occurs.

[0005] However, the aforementioned patent case did not detect the time it took for the user to walk to the detection area or how many steps they took, thus limiting the assessment of rehabilitation effectiveness. Summary of the Invention

[0006] Therefore, to effectively evaluate the self-rehabilitation effect of users at home, the present invention proposes a remote evaluation method for the self-rehabilitation effect, comprising: installing a pressure sensing unit on a handle of a walking aid, with the pressure sensing unit located at the top of the handle; installing a light emitting unit, an ultrasonic emitting unit, and an ultrasonic receiving unit on the walking aid, with the light emitting unit facing the ground, and the ultrasonic emitting unit and the ultrasonic receiving unit both facing the side of the walking aid; the pressure sensing unit, the light emitting unit, the ultrasonic emitting unit, and the ultrasonic receiving unit are all signal-connected to a processing unit; the processing unit controls the light emitting unit to emit a light beam toward a target position in front of the walking aid, and controls the ultrasonic emitting unit to emit an ultrasonic wave toward the side of the walking aid; a user on the walking aid... The user holds the handle on the side, moves the walking aid to the target location, and begins walking on the ground from a starting time. The processing unit calculates a walking time from that starting time. During walking, when the user supports themselves with the handle, the pressure sensing unit detects that the applied pressure exceeds a threshold, and the processing unit accumulates a walking count. When the user walks to the side of the walking aid, the ultrasound waves hit the user and are reflected and received by the ultrasound receiving unit, and the processing unit stops calculating the walking time and stops accumulating the walking count. The processing unit transmits the walking count and walking time to a remote device via a communication unit. The remote device evaluates the user's self-rehabilitation effect based on the walking count, walking time, a historical walking count, and a historical walking time.

[0007] Furthermore, a switch is provided on the grip and signal-connected to the processing unit. The switch controls the on or off of the light emitting unit and / or the ultrasonic emitting unit. The processing unit takes the time when the user operates the switch as the starting time point, or the processing unit takes the time when the ultrasonic wave does not hit the user and is not received by the ultrasonic receiving unit after the walking aid moves as the starting time point.

[0008] Furthermore, an angle control unit is directly or indirectly connected to the light emitting unit; by operating the angle control unit, the emission angle of the light emitting unit can be adjusted.

[0009] Furthermore, the light source is visible light, and this light forms a visible guiding pattern at the target location.

[0010] Furthermore, there is a grip sleeve with a connecting element at each end. The grip sleeve has the pressure sensing unit and the light emitting unit. After the grip sleeve wraps around the grip, the connecting elements at both ends are connected to each other, thereby attaching the grip sleeve to the grip.

[0011] Furthermore, the processing unit transmits the applied pressure to the remote device, which evaluates the user's self-rehabilitation effect based on the number of walks, the walking time, the applied pressure, the historical number of walks, the historical walking time, and a historical applied pressure.

[0012] Furthermore, the user has a rehabilitation leg and a normal leg. The user first uses the normal hand above the normal leg to move the walking aid to the target position, then steps out with the rehabilitation leg, and finally steps out with the normal leg, completing a cycle. If the user has already walked to the side of the walking aid when stepping out with the normal leg, the next cycle continues, moving the walking aid to the next target position. If the user has not yet walked to the side of the walking aid when stepping out with the normal leg, the user alternates stepping out with the rehabilitation leg and the normal leg again until the user walks to the side of the walking aid.

[0013] Furthermore, the user has a rehabilitation leg and a normal leg. The user simultaneously moves the walking aid to the target position and steps out with the rehabilitation leg, and finally steps out with the normal leg, completing a cycle. If the user has already walked to the side of the walking aid when stepping out with the normal leg, the next cycle continues, moving the walking aid to the next target position and stepping out with the rehabilitation leg. If the user has not yet walked to the side of the walking aid when stepping out with the normal leg, the user alternates stepping out with the rehabilitation leg and the normal leg again until the user walks to the side of the walking aid.

[0014] Furthermore, the user has a rehabilitation leg and a normal leg, and the user's hands are normal. When the user holds the handle on the side of the walking aid, the user holds the handle with the hand on the same side as or on the opposite side of the normal leg.

[0015] Based on the above technical features, the following effects can be preferably achieved:

[0016] 1. By using a pressure sensing unit to obtain the number of steps taken and the pressure applied to the rehabilitation leg, and comparing it with the walking time, the system can more accurately and comprehensively assess the user's self-rehabilitation effect.

[0017] 2. After a period of rehabilitation, doctors can adjust the emission angle based on the effectiveness of self-rehabilitation to achieve the goal of progressive rehabilitation.

[0018] 3. Some components are integrated into the grip sleeve, which can not only accommodate different types and sizes of grips, but also make it convenient for users to use walking aids in different places.

[0019] 4. Further obtaining the magnitude of the applied pressure can help physicians confirm whether the user is applying the wrong force.

[0020] 5. Users should step out with their rehabilitation foot first to avoid errors in judging the effectiveness of self-rehabilitation.

[0021] 6. The handle is held by the normal hand on the same side as the normal foot, making it more suitable for patients with ipsilateral limb paralysis due to stroke or other conditions. Simple Explanation of the Diagram

[0036] Based on the above technical features, the main efficacy of the remote assessment method for the autonomous rehabilitation effect of the present invention can be clearly presented in the following embodiments.

[0037] Please refer to Figures 1 through 4, which are the first embodiment of the remote assessment method for the self-rehabilitation effect of the present invention, for evaluating the self-rehabilitation effect at home of user A in Figure 5.

[0038] Preferably, user A has only one rehabilitated foot and the other normal foot, and has already undergone rehabilitation at a medical institution for a period of time. The remote assessment method for the effectiveness of self-rehabilitation in this invention is more suitable for the scenario where user A subsequently performs self-rehabilitation at home. In practical implementation, if user A needs rehabilitation for both feet, the relatively stronger foot can be considered the normal foot, and the relatively weaker foot can be considered the rehabilitated foot.

[0039] The remote assessment method for the effectiveness of this self-rehabilitation includes the following steps:

[0040] A grip sleeve 1 is installed on the grip B11 of the walking aid B1. In this embodiment, the walking aid B1 is a four-legged cane used with one hand.

[0041] The grip sleeve 1 has connecting elements 11 at both ends, such as Velcro, and a switch 12, an angle control unit 13, a pressure sensing unit 14 and a light emitting unit 15 are connected in the center. The angle control unit 13 and the light emitting unit 15 are integrated into one unit to become a lamp with an adjustable emission angle. The angle control unit 13 has a ring of scale lines 131 around its periphery.

[0042] In actual implementation, the switch 12 does not necessarily have to be set on the grip sleeve 1, or it can be set independently in other positions of the walking aid B1. The angle control unit 13 can be an independent knob. In actual implementation, the angle control unit 13 can also be directly or indirectly pivotally connected to the light emitting unit 15 through a linkage mechanism in order to adjust the emission angle.

[0043] After the grip sleeve 1 is wrapped around the grip B11, the connecting elements 11 at both ends are joined together to attach the grip sleeve 1 to the grip B11, with the pressure sensing unit 14 located on top of the grip B11 and the light emitting unit 15 facing the ground. Since some components are integrated into the grip sleeve 1, the grip sleeve 1 can not only accommodate different types and sizes of grips B11, but also allows user A to use existing walking aids B1 in different places such as home, hospital, and clinic without having to replace the walking aids B1.

[0044] Additionally, ultrasonic transmitting unit 2 and ultrasonic receiving unit 3 are both integrated into the walking aid B1 and face the side of the walking aid B1, corresponding to the user A standing on the side of the walking aid B1. The height of ultrasonic transmitting unit 2 and ultrasonic receiving unit 3 corresponds to the distance from the user A's lower leg to their ankle, as shown in Figure 5. In this embodiment, ultrasonic transmitting unit 2 and ultrasonic receiving unit 3 are integrated into the walking aid B1, but in actual implementation, they can also be externally mounted on the outside of the walking aid B1.

[0045] Switch 12, angle control unit 13, pressure sensing unit 14, light emitting unit 15, ultrasonic emitting unit 2 and ultrasonic receiving unit 3 are all signal connected to processing unit 4, and processing unit 4 is signal connected to remote device 6 via communication unit 5.

[0046] Preferably, switch 12 has three modes, including off mode, standby mode and recovery mode, which can control the light emitting unit 15 and ultrasonic emitting unit 2 to be turned on or off.

[0047] In a preferred embodiment of the present invention, the light emitted by the light emitting unit 15 is visible light, which can form a guide pattern C as shown in Figure 5 after hitting the ground, such as a straight line, a circle, a square, etc.

[0048] The processing unit 4 and the communication unit 5 can be integrated into the user A's mobile phone, tablet computer, computer, etc. The power required by components such as switch 12, pressure sensing unit 14, light emitting unit 15, ultrasonic emitting unit 2 and ultrasonic receiving unit 3 can be supplied by a power supply unit located in the grip sleeve 1 or a separate power supply unit, such as a battery, although the power supply unit is not shown in the drawings of this invention.

[0049] Please refer to Figure 1, Figure 2 and Figure 5. When not in use, switch 12 is in the off mode. After the grip sleeve 1 is configured, user A can switch switch 12 to the ready mode and stand on the side of the walking aid B1.

[0050] In this embodiment, user A's left foot and left hand are paralyzed. The rehabilitation leg is the left foot, the normal leg is the right foot, and the normal hand is the right hand. User A can stand to the left of the walking aid B1 and hold the handle sleeve 1 and handle B11 with the normal hand on the same side as the normal leg. This method is suitable for users A who have ipsilateral paralysis of the limbs due to conditions such as stroke. In actual implementation, for users A who have only injured their feet but whose hands are normal, it is not limited to holding the handle sleeve 1 and handle B11 with the hand on the same side as the normal leg.

[0051] At this time, the processing unit 4 can first control the ultrasonic transmitting unit 2 to emit ultrasonic waves toward the side of the walking aid B1. After the ultrasonic waves hit the user A, they will be reflected and received by the ultrasonic receiving unit 3. The processing unit 4 can then know that the user A has been positioned on the side of the walking aid B1.

[0052] Next, user A can switch switch 12 to rehabilitation mode, and processing unit 4 will control light emitting unit 15 to emit light toward the target position in front of walking aid B1 to form guide pattern C.

[0053] Please refer to Figures 5 through 7, and in conjunction with Figures 1 and 2. User A will execute the following three-point pattern loop starting from the initial time point:

[0054] Step 1: User A holds the grip sleeve 1 and the grip B11 and moves the walking aid B1 to the target position. At the same time, the light emitting unit 15 will form a guiding pattern C towards the next target position in front of the walking aid B1.

[0055] Step 2: With the support of walking aid B1, user A steps out with the rehabilitation foot, as shown in Figure 8.

[0056] Step 3: User A steps out with their normal foot, as shown in Figure 9.

[0057] If user A has not reached the side of walking aid B1 after taking the third step with the normal foot, then repeat the second step with the rehabilitation foot and the third step with the normal foot alternately until reaching the side of walking aid B1.

[0058] If user A has reached the side of walking aid B1, the next cycle continues, and walking aid B1 is moved to the next target position.

[0059] Preferably, user A will be told to step out with the rehabilitation foot first, which can avoid the judgment error of the self-rehabilitation effect obtained in the subsequent evaluation. The processing unit 4 can determine which foot user A starts with based on the time difference of the ultrasound received by the ultrasound receiving unit 3, etc. If user A starts with the non-rehabilitation foot, the processing unit 4 can not collect the relevant data of this rehabilitation.

[0060] The emission angle of the light emitted by the light emitting unit 15 to the target position can be set in advance by medical personnel through the angle control unit 13, based on the average walking distance of user A in the past medical institutions and the height of the walking aid B1, preferably based on the distance that can be reached in one step. In actual implementation, the emission angle can be determined in conjunction with the scale line 131 in the third figure. For example, each rotation of the scale line 131 is equivalent to a rotation of 5 degrees, or the scale line 131 itself is marked with an angle value, etc. The present invention does not impose any limitations.

[0061] The processing unit 4 uses the time of switching switch 12 as the starting time point, or the time when the ultrasound waves did not reach user A and were not received by the ultrasound receiving unit 3 after the walking aid B1 was moved as the starting time point, and calculates the walking time from the starting time point. Preferably, the processing unit 4 can automatically or according to the user A's needs select one of the above-mentioned starting time point determination methods, and maintain the same starting time point determination method during subsequent rehabilitation.

[0062] During user A's walking process, when user A supports themselves with their rehabilitation leg and the handle B11, the pressure sensing unit 14 detects that the applied pressure from user A exceeds a threshold. The processing unit 4 then accumulates the number of walks and obtains the applied pressure value. The threshold can be, for example, 0.75 times the minimum or average applied pressure value measured by user A in medical institutions in the past, and is pre-input to the processing unit 4 by medical personnel. In actual implementation, since the handle B11 is usually not needed for support when supporting with the normal leg, or even if it is used for support, the pressure sensing unit 14 will not detect that the applied pressure from user A exceeds the threshold. Therefore, the number of times the pressure sensing unit 14 detects that the applied pressure from user A exceeds the threshold can be simply set, and multiplied by 2, to obtain the number of walks.

[0063] When user A walks to the side of walking aid B1, the ultrasound waves hit user A and are received by the ultrasound receiving unit 3. Then, the processing unit 4 stops calculating the walking time and stops accumulating the number of walks.

[0064] After the processing unit 4 stops calculating walking time and stops accumulating walking counts, it can transmit the walking counts, walking time, and applied pressure to the remote device 6 via the communication unit 5 at regular or irregular intervals. For example, it can transmit the data to the medical staff's computer once a day or to the medical staff's computer after each rehabilitation session. The remote device 6 then evaluates the user A's self-rehabilitation effect based on the walking counts, walking time, applied pressure, historical walking counts, historical walking time, and historical applied pressure. For example, it can compare the walking counts with historical walking counts, walking time with historical walking time, and applied pressure with historical applied pressure.

[0065] Preferably, the historical number of steps and the historical walking time can be the number of steps and the time spent by user A in the past walking a known distance in a medical institution, respectively. This known distance is the same as or similar to the distance from the starting position to the target position during this rehabilitation, so as to eliminate the influence of the large difference between the two rehabilitation walking distances.

[0066] For example, if the number of steps taken this time is more than the number of steps taken in the past, and the walking time is longer than the walking time in the past, it means that the strength of the leg being rehabilitated may have been greatly weakened. The effect of self-rehabilitation can be presented in words such as obvious deterioration, obvious regression, or obviously poor rehabilitation effect, or in comparative charts.

[0067] If the number of steps taken this time is the same as the number of steps taken in the past, but the walking time is longer than the past walking time, or if the walking time taken this time is the same as the past walking time, but the number of steps taken is more than the past number of steps, it means that the strength of the leg being rehabilitated may still be slightly weakened. The effect of self-rehabilitation can be presented in words such as deterioration, regression, or poor rehabilitation effect, or in comparative charts.

[0068] Conversely, if the number of steps taken this time is the same as the number of steps taken in the past, but the walking time is shorter than the past walking time, or if the walking time taken this time is the same as the past walking time, but the number of steps taken is less than the past number of steps, it means that the strength of the leg being rehabilitated may have increased slightly. The effect of self-rehabilitation can be presented in words such as optimization, progress, or good rehabilitation effect, or in comparative charts.

[0069] If the number of steps taken this time is less than the number of steps taken in the past, and the walking time is shorter than the walking time in the past, it means that the strength of the leg being rehabilitated may have been greatly enhanced. The effect of self-rehabilitation can be presented in words such as obvious optimization, obvious progress, and excellent rehabilitation effect, or in comparative charts.

[0070] In this way, medical personnel can quickly know the rehabilitation effect of user A after rehabilitation at home, and whether the strength of the rehabilitated foot has improved.

[0071] When the applied pressure exceeds the historical maximum pressure measured in medical institutions, or consistently exceeds the historical average pressure by, for example, 1.25 times, the effect of autonomous rehabilitation can be presented as text indicating abnormal or incorrect force application, or as a graph showing changes in applied pressure. This helps medical personnel understand whether user A has incorrectly applied excessive force with their hands, resulting in incomplete rehabilitation of the leg. Even without considering the specific numerical value of applied pressure, simply comparing and obtaining the effect of autonomous rehabilitation is still one of the feasible embodiments of this invention and can effectively evaluate the rehabilitation effect.

[0072] Every step, walking time, and pressure applied by user A during home rehabilitation can be stored as historical walking counts, historical walking times, and historical pressure applied. After a period of home rehabilitation, medical personnel can adjust the emission angle by operating the angle control unit 13 themselves or by notifying user A, based on the effectiveness of the self-rehabilitation, to achieve the goal of progressive rehabilitation.

[0073] Please refer to Figures 10 to 12. In addition to the three-point pattern cycle mentioned above, if User A has made progress after a period of rehabilitation, or if their symptoms were originally mild, they can switch to the following two-point pattern cycle:

[0074] Step 1: Following the guidance of the guide graphic C, user A moves the walking aid B1 to the target position and steps out with the support of the walking aid B1. At this time, the guide graphic C will also be formed at the next target position in front of the walking aid B1, as shown in Figure 11.

[0075] Step 2: User A steps out with their normal foot, as shown in Figure 12.

[0076] Similar to the three-point pattern cycle, user A can decide whether to alternate stepping out with the rehabilitation foot and the normal foot, or to continue the cycle by moving the walking aid B1 and stepping out with the rehabilitation foot, depending on whether they have walked to the side of the walking aid B1.

[0077] In Figures 5, 7 to 12, footprints and dots are used to indicate the positions of user A's feet and walking aid B1 in a top-down view, and arrows are used to indicate which foot or walking aid B1 was moved in each figure.

[0078] Please refer to Figures 13 and 14, which are the second embodiment of the remote assessment method for the autonomous rehabilitation effect of the present invention. The difference between this embodiment and the first embodiment is that in the first embodiment [please refer to Figure 4 for the first embodiment], the walking aid B1 is a four-legged cane used with one hand; while in this embodiment, the walking aid B2 is a walking aid used with both hands.

[0079] Preferably, there are two sets of grip sleeves 1, which are respectively installed on the grips B21 on both sides so that the user A can grip with both hands.

[0080] In actual implementation, depending on the requirements of the position of the guide graphic C, such as being located directly in front of the walking aid B2, the two sets of grip sleeves 1 may not be exactly the same and may be symmetrically arranged. They may even use different light emitting units 15 than those in the first embodiment to form a larger guide graphic C, so that the two sets of guide graphics C together form a complete graphic, which better guides the user A on how to move the walking aid B1.

[0081] However, the rest of the operation process is the same as or corresponds to the first embodiment, and the same component symbols are used as in the first embodiment. The two sets of grip sleeves 1 are not distinguished, and the operation process of this embodiment will not be repeated here.

[0082] Based on the above description of the embodiments, one can fully understand the operation, use and effects of the present invention. However, the above embodiments are only preferred embodiments of the present invention and should not be used to limit the scope of the present invention. Simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention are all within the scope of the present invention.
