An improved leg brace having a thigh frame, a shank frame, a knee assembly rotatably coupling the thigh frame to the shank frame, and a shoe component attached to the shank frame; the knee assembly having a spring, clutch, operatively coupled to the spring; and programmable means for engaging the clutch at a selected angle between the thigh frame and shank frame, wherein the spring delivers is an assistance force when the clutch is engaged at the selected angle between the thigh frame and shank frame. |
| Claim: | 2. The leg brace of claim 1 , further comprising: a second knee assembly configured so that, when in use, one knee assembly is on the medial side of the leg and the other knee assembly is on the lateral side of the leg. |
| Claim: | 3. The leg brace of claim 1 , further comprising: programmable means for releasing the clutch at a selected angle between the thigh frame and shank frame. |
| Claim: | 4. The leg brace of claim 1 , wherein the clutch is a one-way clutch. |
| Claim: | 5. The leg brace of claim 1 , further comprising means for programming the maximum permitted tibiofemoral joint forces during knee flexion. |
| Claim: | 6. The leg brace of claim 1 , further comprising a command module in wired or wireless communication with the programmable means for engaging the clutch at the selected angle. |
| Claim: | 7. The leg brace of claim 1 , further comprising automatic means for adjusting the selected angle wherein the clutch is engaged, during an extended period of ambulation. |
| Claim: | 8. The leg brace of claim 1 , further comprising programmable means for situationally adjusting the selected angle wherein the clutch is engaged. |
| Claim: | 9. The leg brace of claim 1 , further comprising automatic means for adjusting the selected angle at which the clutch is engaged in accordance with a training schedule. |
| Claim: | 10. A leg brace, comprising: a. a shank frame; b. a thigh frame; c. at least one knee joint, rotatably coupling the shank frame to the thigh frame; d. at least one non-linear torsion spring having a torsional axis at the at least one knee joint wherein the torsion spring hardens with increasing angle of knee flexion; e. at least one clutch with an input arbor coupled to the at least one non-linear torsion spring and an output arbor coupled to: i. the thigh frame; or ii. the shank frame; f. a programmable controller, operatively coupled to the at least one clutch, for: i. engaging the at least one clutch at a selected angle between the thigh frame and the shank frame in relation to heel strike during ambulation; and ii. releasing the at least one clutch at a selected angle between the thigh frame and the shank frame during knee extension, wherein the at least one non-linear torsion spring is delivers an assistance force when the clutch is engaged at the selected angle between the thigh frame and shank frame. |
| Claim: | 11. The leg brace of claim 10 , further comprising a command module, in wired or wireless communication with the programmable controller, for situationally selecting the angle of knee flexion at which the at least one clutch is engaged. |
| Claim: | 12. The leg brace of claim 10 , wherein the at least one clutch is a one-way clutch. |
| Claim: | 13. The leg brace of claim 10 , further comprising automatic means for adjusting the selected angle wherein the clutch is engaged, during an extended period of ambulation. |
| Claim: | 14. The leg brace of claim 10 , further comprising programmable means for situationally adjusting the selected angle wherein the clutch is engaged. |
| Claim: | 15. The leg brace of claim 10 , further comprising automatic means for adjusting the selected angle at which the clutch is engaged in accordance with a training schedule. |
