Abstract
Description
Technical Field
[0001] This invention relates to a device for mobilizing the human musculoskeletal system.
[0002] More specifically, but not limitingly, the field of the invention is devices for treating or diagnosing piriformis syndrome. Background Technology
[0003] Piriformis syndrome is usually the result of sciatic nerve compression or piriformis muscle irritation of the sciatic nerve, which causes hip pain and sometimes sciatica.
[0004] Piriformis syndrome is common and affects multiple populations: athletes, especially high-level athletes, pregnant women or overweight people, and the last group of people with different characteristics and activity levels, particularly certain occupational categories that are at risk due to their work posture.
[0005] To alleviate or treat piriformis syndrome, the following may be considered:
[0006] - Specific exercises for stretching the hips, and / or
[0007] - Surgery, and / or

[0009] Different manipulations are known that can be used to diagnose piriformis syndrome and / or stretch the piriformis muscle and / or relieve the musculoskeletal system associated with piriformis syndrome, such as the "FAIR" method. This involves flexing the leg at the hip, then adducting it, and finally internally rotating it. The purpose of this series of movements is to stretch the piriformis muscle in a certain way, which usually results in pain feedback in patients with piriformis syndrome.
[0010] Solutions that make it easier to perform the above procedures are known, such as Piri. This solution allows the knee (and leg) to be moved via a handle attached to the knee (and leg).

[0093] Since these embodiments are by no means limiting, variations of the invention that include only a selection of features described or shown below, separate from the other features described or shown (even if the selection is separate in a phrase containing those other features), are particularly conceivable, provided that the selection of features is sufficient to provide a technical advantage or differentiate the invention from the prior art.

[0094] In all of the following embodiments of device 100, device 100 for mobilizing (by compressing the knee) the musculoskeletal system of a human user includes:
[0095] - Knee brace 2, configured to cover the knee 3 of a human user to hold the knee brace 2 supported on the knee 3 (at least around the periphery of the knee 3), and / or to hold the knee 3 within the knee brace 2, and configured to apply a modulating force (typically greater than 30 kg and / or less than 120 kg) on the knee 3 covered by the knee brace 2:
[0096] *This adjusting force applies pressure to the knee 3 and directs it toward the bearing surface 5, which is designed to support the user's pelvis, and
[0097] *The adjusting force has a direction from the knee pad 2 to the bearing surface 5 and is contained in the adjusting force application plane 4.
[0098] The force of adjustment is therefore to compress the knee, preferably to generate a compressive force on the pelvis.
[0099] As shown in the embodiments of all the figures, the force application plane 4 is preferably perpendicular to the bearing surface 5.
[0100] Surface 5 is preferably flat.
[0101] The device 100 also includes means for increasing (preferably gradually or continuously) the adjustment force, preferably from zero or low initial values (typically the weight of the knee brace 2, the presence of other components supporting the user's knee 3, or a certain initial tension due to the initial arrangement of the device, in particular). For some designs, this initial tension may include a specific pre-stretching action of the device of about 10 to 300 N to best position the knee brace and to make the arrangement of the adjustment force more efficient. For example, by activating the pawls of each adjustment bracket in the optimal mode, or... Figures 10 to 13 In the design, components are arranged for general adjustment of the strip length, artificially generating the pre-stretch.
[0102] The device 100 also includes a device 7 configured to limit the relative movement of the knee brace 2 relative to the bearing surface 5, according to the stroke limited by the device 7, during the amplification of the adjusting force by the force amplification device 6.
[0103] The position of the adjusting force application plane 4 can vary during the restricted stroke.
[0104] Surface 5 is a limited area designed to receive the user's pelvis.
[0105] In all the following embodiments, the relative movement of the knee brace 2 with respect to the bearing surface 5 will be shown through the movement of the knee brace 2. Each of these embodiments can be altered by reversing or changing the mobility of the knee brace 2 and the surface 5 so that the knee brace 2 and / or the surface 5 are movable.
[0106] Surface 5 is part of the device 100, and its form is, for example:
[0107] - Base (for the user's pelvis), and / or backrest (for the user's back), and / or
[0108] - The backrest of a chair or armchair ( Figure 1 , 2 5, 6 and 7), or
[0109] - Mat, table, or bed ( Figure 3 , 4 and 8 to 23 and 25 to 28).
[0110] In one variant, surface 5 is not part of device 100, which includes fastening means (e.g., jaw system) configured to fasten device 100 to surface 5.
[0111] "Coverage" refers to the knee brace 2 being set (at least during the application of a modulating force exceeding a certain threshold, typically more than 20 kg) to conform (through or without the deformation of the knee brace) to the shape of the knee 3 (typically based on a radius of curvature of at least 3 cm) to prevent the knee from sliding laterally off the knee brace 2 when the knee brace 2 contacts and covers the knee 3.
[0112] Even though not necessarily shown for every embodiment in all the figures, the knee brace 2 and / or the bearing surface 5 may include at least one elastic (in extension and / or in compression) recovery device 111.
[0113] Each recovery device 111 has a given stiffness configured to affect the modulating force applied from the knee brace 2 toward the bearing surface 5. For example, the surface 5 may be a spring-filled pad, and / or the knee brace 2 may be made of an elastically treated material and / or equipped with springs.
[0114] Regarding this design, the design with a single recovery device 111 will be described here, more specifically for Figure 1 , 2 Designs of types 1, 2, 3, 5, 6, 7, and 8, as well as types 19 to 22, have been tested using the following recovery devices:
[0115] - A very flexible assembly, which is therefore suitable for weak and / or sensitive and / or small patients:
[0116] • An initial force F° equal to 254 N; in other words, the minimum force required to achieve the first deformation of the spring.
[0117] The stiffness coefficient R of a spring is equal to 1.84 N / mm.
[0118] For this device, a considerable extension is often noted when using extendable link elements. When the extension reaches a value of 20mm to 50mm, the patient stops stretching their muscles.
[0119] Here, the 20mm extension corresponds to the applied force: (F°+(R*20))=290N.
[0120] The 50mm extension corresponds to an applied force of (F° + (R*50)) = 346N. This force is greater, but still very reasonable because it poses little risk to the patient.
[0121] - The assembly is very rigid, making it suitable for patients in good physical condition:
[0122] • An initial force F° equal to 800N, in other words, the minimum force required to achieve the first deformation of the spring.
[0123] The stiffness coefficient R of a spring equal to 55.8 N / mm.
[0124] For this device, it is often noted that the extension of the extendable link element is quite small. When the extension reaches a value of 10mm to 15mm, the patient stops their muscle stretching.
[0125] The 10mm extension corresponds to the force applied to the spring as follows: (F°+(R*10))=1358N, which already corresponds to a high pressure.
[0126] The 15mm extension corresponds to the following force applied to the spring: (F° + (R*15)) = 1637N.
[0127] The first assembly can be considered well suited for the weakest patients, and the second assembly can be considered well suited for patients in very good physical condition, but it is important to understand that the most important thing is the range of pressure applied to the knee, which is usually 300N to 1600N.
[0128] Therefore, the stiffness of the recovery device 111 is typically greater than 0.5 N / mm and / or less than 70 N / mm.
[0129] In this specification, an element that is "elastic in extension" preferably refers to an element that, when subjected to a tensile force of 100 kg parallel to its length (preferably parallel to the adjusting force), extends beyond its initial length by more than 1% (preferably more than 10%).
[0130] In this specification, an element that is "compressible" or "elastic in compression" preferably refers to an element that shortens by more than 1% (preferably more than 10%) of its initial length when subjected to a pressure of 100 kg parallel to its length (preferably parallel to the adjusting force).
[0131] In this specification, a “non-extendable” element preferably refers to an element that does not extend more than 1% of its initial length when subjected to a tensile force of 100 kg parallel to its length (preferably parallel to the adjusting force).
[0132] In this specification, an "incompressible" element preferably refers to an element that does not shorten by more than 1% of its initial length when subjected to a pressure of 100 kg parallel to its length (preferably parallel to the regulating force).
[0133] exist Figure 2 , 4 In the specific cases of 6 and 8 to 23 and 25 to 28, device 100 includes at least one linking element 9, which will:
[0134] -Attach the knee brace 2 or the components to the knee brace 2.
[0135] - Components connected to or attached to the bearing surface 5.
[0136] The at least one linking element 9 typically includes at least one strip or rod. Even if this is not necessarily shown, it is present in most designs, especially... Figure 3 , 4 In each of the embodiments 6 and 8 to 23 and 25 to 28, at least one recovery device 11, which is elastic in extension and / or compression, may be arranged along the at least one linking element 9, the recovery device 11 having a given stiffness or elasticity along the mechanical connection connecting the knee brace 2 or the element attached to the knee brace 2 to the bearing surface 5 or the element attached to the bearing surface 5.
[0137] As described for device 111, the stiffness of each recovery device 11 is therefore typically greater than 0.5 N / mm and / or less than 70 N / mm.
[0138] These devices 11 have a progressive effect, which provides ease of use and safety, while in particular avoiding an excessively sudden increase and / or an excessively high increase in the force applied to the knee 3 by the knee brace 2.
[0139] These devices 11 can be used to limit the applied force, especially for the purpose of ensuring the safety of the device 100 during its own use. For example, for an assembly with a single spring stiffness coefficient of 1.84 N / mm as described above, it is difficult to achieve a force greater than 50 kg, because this would require the spring to extend 130 mm instead of 50 mm, which is unlikely or can be easily avoided by the user and professionals.
[0140] The device 100 preferably includes a means 13 for replacing the at least one recovery device 11 with different recovery devices 11 having different stiffness and / or elasticity (so that the safety is adapted to different characteristics or different forms for the user); and / or a means 14 for changing the stiffness of the at least one recovery device 11.
[0141] Each link element 9 is:
[0142] -exist Figure 2 In the case of a spring: it is elastic in both extension and compression.
[0143] -exist Figure 6 In the case of: a non-extendable and non-compressible (panel) (which may have a compressible area 2, such as a shock-absorbing pad),
[0144] -exist Figure 4 , 8 In cases 9, 10, 11, 12, 13 to 18 and 23 and 25 to 28: without the recovery device 11, it is non-extendable but compressible (strip); and, with the recovery device 11 present, it is elastic in extension and compressible.
[0145] -exist Figures 19 to 22 In the case where: without the recovery device 11, it is neither extendable nor compressible (rod); in the case where the recovery device 11 is present, it is elastic in both extension and compression.
[0146] Reference Figures 1 to 5 Sections 8 to 12 will first describe a first series of embodiments of device 100.
[0147] exist Figures 1 to 5 In embodiments 8 to 12, the device 7, configured to limit the relative movement of the knee 3 relative to the bearing surface 5, is configured to maintain the position of the force application plane 4, which is parallel to the user's medial plane (i.e., in the user's sagittal plane), fixed during the increase of the force adjustment; more precisely, to maintain the direction of the force adjustment fixed during the increase of the force adjustment. This fixed direction of the force adjustment is preferably perpendicular to the surface 5 and along the axis of the femur.
[0148] If the adjusting force is not perpendicular to surface 5, the user will feel that the component of the applied force is parallel to surface 5. This can cause physical discomfort through the tension it generates, and if the component parallel to surface 5 is large, it may cause the patient's body to shift by sliding on surface 5, unless a wedging system is provided to prevent this phenomenon. The device according to the invention therefore preferably includes such a wedging device configured to prevent the pelvis from sliding on surface 5. This point is valid if the adjusting force is in the sagittal plane, and it is also valid if the adjusting force is not in the sagittal plane.
[0149] If the direction of the force is not along the axis of the femur, the user will feel a component of the movement that causes the femur to lift or lower the knee. The patient may resist the force by activating the muscles in their leg, but this is detrimental to the desired effect of relaxing the muscles. The point holds true if the force is in the sagittal plane, and it also holds true if the force is not in the sagittal plane.
[0150] The user's "midplane" is the plane that separates the left and right halves of the user's body, and is preferably approximately the plane of symmetry of the body (when the latter extends along the body's arms). It is one of countless "sagittal planes" that are parallel to the midplane.
[0151] The device 6 for increasing the adjustment force is configured to increase the adjustment force while reducing the distance between the knee pad 2 and the bearing surface 5.
[0152] The device 7, configured to limit the relative movement of the knee brace 2 relative to the bearing surface 5 based on the limited stroke, is configured to limit the relative movement of the knee brace 2 relative to the bearing surface 5 based on the translational movement of the knee brace 2 in the direction of the surface 5.
[0153] Plane 4 and Figure 1 , 2 The planes of 3 and 5 are parallel.
[0154] Reference Figure 1 In a first embodiment of the device 100, the device 6 for increasing the adjustment force includes a gripping element (e.g., a lever or handle) attached to the knee brace 2, which the user manually pulls on the bearing surface 5 to pull the knee brace 2 toward the bearing surface when the user's pelvis is on the bearing surface 5.
[0155] The reinforcement 24 is set to abut against the surface 5 to fix its pelvis.
[0156] The bearing surface 5 forms part of the device 100 and includes the backrest of a chair or armchair.
[0157] The device 7 includes a pivoting joint that allows the knee brace 2 to rotate parallel to the plane 4, and it remains fixed.
[0158] For example, including a connecting member or a deformable parallelogram mechanism (not shown) between the pivoting joint 7 and the knee brace 2 can also restrict the movement of the knee brace 2 perpendicular to the surface 5. However, in one deformation, the direction of force application is not strictly constant, but still remains within a few degrees (typically ±15 degrees), approximately perpendicular to the surface 5.
[0159] Reference Figure 2 The second embodiment of device 100 will be described only. Figure 1 The difference from the first embodiment.
[0160] The device 6 for increasing the adjustment force includes a restoring device, such as a spring, that applies a restoring force from the knee brace 2 toward the bearing surface 5, and a gripping device (such as a lever or handle) attached to the knee brace 2, which the user can manually pull when their pelvis is on the bearing surface 5 to manually compensate for the restoring force. The adjustment force increases by pushing or pulling less and less.
[0161] The restoring device (which is typically spring-type) forms link element 9, which will:
[0162] - Knee pad 2 or components attached to knee pad 2,
[0163] - Components connected to or attached to the bearing surface 5.
[0164] Reference Figure 3 In a third embodiment of the device 100, the device 6 for increasing the mobilization force includes a step 26 attached to the knee pad 2 and configured to receive the foot of a professional separated from the user, so as to increase the mobilization force by increasing the force applied by the professional on the step 26.
[0165] This effect can be reduced by using a lever-arm type mechanical system (e.g., if the professional applies a weight less than the adjustment force to be applied).
[0166] The device 100 preferably includes means (e.g., a frame and / or pawl type) for accumulating the desired mobilizing force by applying successive forces, the successive force accumulation allowing for gradualness to provide force in a well-quantified manner.
[0167] The bearing surface 5 forms part of the device 100 and includes a table or bed.
[0168] The device 7 includes a guide 27 configured to guide the portion 25 that connects the knee brace 2 to the step 26. For example, the guide 27 is a hollow tube extending perpendicular to the surface 5, and the connecting portion 25 that connects the knee brace 2 to the step 26 is a sliding pin located in the concentric tube 27 perpendicular to the surface 5.
[0169] The device 100 may include at least one recovery device 11 (not shown) that is elastic (in extension and / or in compression, at least in extension) along the link portion 25, the recovery device 11 having a given stiffness or elasticity along the mechanical link 25 that connects the knee brace 2 to the step 26.
[0170] Each recovery device 11 has a stiffness of typical value.
[0171] Instead, a design with two linking elements 9, each equipped with the same recovery device 11, is particularly suitable for Figure 5 , 910, 13, 14 to 18, 21, 23, and using the following recovery device, for Figures 25 to 28 The design was tested:
[0172] - A very flexible assembly, which is therefore suitable for weak and / or sensitive and / or small patients:
[0173] • An initial force F° equal to 127 N, in other words, the minimum force required to achieve the first deformation of the spring.
[0174] • The stiffness coefficient R of a spring that is equal to 0.92 N / mm.
[0175] For this device, a considerable extension is often noted when using extendable link elements. When the extension reaches a value of 20mm to 50mm, the patient stops stretching their muscles.
[0176] Here, the 20mm extension corresponds to the force applied to the two springs as follows: 2*(F°+(R*20))=290N
[0177] The 50mm extension corresponds to the force applied to the two springs as follows: 2*(F°+(R*50))=346N. This force is greater, but still a very reasonable force because it poses little risk to the patient.
[0178] - The assembly is very rigid, making it suitable for patients in good physical condition:
[0179] • An initial force F° equal to 400N, in other words, the minimum force required to achieve the first deformation of the spring.
[0180] • The stiffness coefficient R of a spring equal to 27.9 N / mm.
[0181] For this device, it is often noted that the extension of the extendable link element is quite small. When the extension reaches a value of 10mm to 15mm, the patient stops stretching their muscles.
[0182] The 10mm extension corresponds to the force applied to the two springs as follows: 2*(F°+(R*10))=1358N, which already corresponds to a high pressure.
[0183] The 15mm extension corresponds to the force applied to the two springs as follows: 2*(F°+(R*15))=1637N.
[0184] The first group can be considered well-suited for the weakest patients, and the second group can be considered well-suited for patients in very good physical condition, but it is important to understand that the most important factor is the range of pressure applied to the knee, typically between 300N and 1600N. Choosing the spring characteristics is one thing, but the way they are used to generate pressure is another. For example, a very weak person could use a second device with a spring stiffness of 27.9 N / m, in a posture that avoids significant delay, and thus withstand only 300 or 400 N of pressure.
[0185] To further illustrate, for patients in good physical condition, a spring with a slightly higher stiffness than the second set of springs proposed can be selected:
[0186] The initial force F° is equal to 510N, not 400N.
[0187] The stiffness coefficient R of the spring is 31.8 N / mm, not 27.9 N / mm.
[0188] For this device, a patient using an extended stroke up to 5 mm will apply a force (for two springs) equal to 2*(F°+(R*5))=1338N, and a patient using an extended stroke up to 10 mm will apply a force (for two springs) of 2*(F°+(K*10))=1656N.
[0189] It can be seen that the force obtained here is quite similar to that obtained for the previous spring pair. The slightly smaller stroke for applying pressure simply compensates for the use of a spring with slightly greater stiffness.
[0190] Finally, it should be noted that the use of such a recovery device 11 is optional, and it is feasible to apply tension directly to the knee, assuming the user knows how to quantify the pressure.
[0191] Each recovery device 11 therefore typically has a stiffness greater than 0.5 N / mm and / or less than 70 N / mm.
[0192] The device 100 may include means (not shown) for replacing the at least one recovery device 11 with different recovery devices to change the stiffness of the at least one recovery device 11, which applies the same principle as in the thirteenth, fourteenth, fifteenth, or sixteenth embodiments described below. This may include, for example, multiple interchangeable spring groups and / or springs with adjustable force.
[0193] Reference Figure 4 In a fourth embodiment of the device 100, the bearing surface 5 forms part of the device 100 and includes a table or bed.

These two or four strips are respectively hooked to two opposite sides of the knee brace 2 (one strip on each side of the knee brace 2), or a pair of strips on each side (i.e., the right or left side of the user relative to its mid-plane).
[0198] The device 6 for increasing the adjustment force includes a device 12 for shortening at least one or each of the linking elements 9, more specifically, a device 12 for shortening at least one or each of the strips. These devices 12 typically include a winder (e.g., a manual winder, which typically has a crank) for each strip, or a winder shared by multiple strips.
[0199] exist Figure 4 In this case, each strip is equipped with a winder to balance the tension of the two strips.
[0200] Two strips or two pairs of strips are configured to pull respectively toward the right and left sides of the sagittal plane of the user whose knee 3 is covered by the knee brace 2 (the sagittal plane passes through the knee brace 2).
[0201] The device 7 includes two strips or two pairs of strips configured to pull the knee brace 2 in a balanced manner to the right and left sides to keep the adjustment force in a fixed plane 4 parallel to the user's midline plane.
[0202] In the preferred case with four strips (not shown), each pair of strips on the right or left side of the user's sagittal plane (which passes through the knee brace 2) comprises two strips arranged to pull forward and backward in a balanced manner parallel to the user's sagittal plane.
[0203] It should be noted that the use of four strips allows the knee brace to be driven according to the limited range of motion, without requiring the patient to exert force to maintain their posture, even if the direction of the force is not in the axis of the femur.
[0204] Reference Figure 5 In a fifth embodiment of the device 100, the bearing surface 5 forms part of the device 100 and includes the backrest of a chair or armchair.

[0210] In this eighth embodiment, only one strip 9 is equipped with a winder 12, and the other strip 9 is equipped with a spring 11. The two strips are attached to each other and follow one another, so that the winder acts on both strips simultaneously, thereby pulling the knee brace 2 to the right and left in a balanced manner to keep the adjustment force in a fixed plane 4 parallel to the user's center plane.
[0211] refer to Figure 9 It will only be in relation to its Figure 8 The ninth embodiment of the device 100 is described in light of the differences between the eighth embodiment and the previous one.
[0212] In this embodiment, each strip 9 is not connected to the surface 5, but is connected to an element 16 attached to the surface 5 and configured to shorten the length of each strip 9.
[0213] Each element 16 is configured as follows:
[0214] - Blocks lateral movement of the knee 3 and thereby restricts relative movement of the knee brace 2 parallel to the plane 4, and / or
[0215] - Allows for anchoring points of the strips higher than surface 5 (i.e. closer to knee brace 3), which makes it possible to reduce the instability of knee brace 2.
[0216] In this embodiment, as in other embodiments, the means for shortening at least one of the linking elements can be mechanized.

[0238] Plane 4 is parallel to Figure 6 , 13 The planes 15, 17, and 18.
[0239] Plane 4 is perpendicular to surface 5.
[0240] The bearing surface 5 forms part of the device 100 and includes a table or bed.
[0241] The direction of the adjusting force is parallel to the straight line perpendicular to surface 5 within ±30 degrees.
[0242] The direction of the adjusting force forms an angle β with a straight line perpendicular to surface 5 and passing through axis 8 or 30:
[0243] - When the adjusting force is borne by an inclined line relative to the line perpendicular to surface 5 on the user's foot side, β is positive (e.g., Figure 13 (as shown),
[0244] - When the regulating force is borne by an inclined straight line relative to the line perpendicular to surface 5 on the user's head side, β is negative (e.g., Figure 15 (As shown).
[0245] The value of this angle β decreases during the increase of the mobilization force.

[0263] Reference Figures 13 to 18 In a thirteenth embodiment of device 100, the at least one linking element 9 includes two strips 9 that connect both sides of the knee brace 2 to two anchor points along the pivot pin 8. Each strip 9 connects the knee brace 2 to a surface 5 or an element attached to the bearing surface 5. The two strips 9 are hooked to two opposite sides of the knee brace 2 (one strip on each side of the knee brace).

Typically, the connector allows the knee brace 2 to be hooked to the element 9 (strip) and also allows the recovery device 11 to be changed for different stiffness values. This allows the device to be adjusted to different ranges of applied adjustment force, from the lowest value (for child users or users who are weak in the area of stretch adjustment due to age, wounds, or surgery) to the highest value (for well-fitting adult users, such as athletes, in particular).
[0279] Each recovery device 11 can move along element 9 ( Figure 17 b) Arranged or placed at the end of element 9 ( Figure 16 , Figure 17 c).
