A biomechanical review of the anterior cruciate ligament deficient knee shows that the unbraced knee undergoes instability once its angular velocity exceeds normal cadence rate. It also shows that various braces that utilize extension limits for purposes of preventing subluxation and tibial rotation introduce abnormal gait and posture responses, which may impose on the patient's activities. A speed-regulated, viscoelastic knee brace has been designed, fabricated, and tested on two patients. The brace allows full range of knee motion and reduces the angular velocity of the tibia from near-full extension to neutral at normal, non-unstabilizing walking speeds. Capability is incorporated for adjusting the terminal angular velocity for each individual patient as well as for the same patient during the recovery period.
对前交叉韧带损伤膝关节的生物力学研究表明，未加支撑的膝关节一旦角速度超过正常节奏速率，就会出现不稳定。研究还表明，各种利用伸展限制来防止半脱位和胫骨旋转的支具会引发异常的步态和姿势反应，这可能会影响患者的活动。一种速度调节型粘弹性膝关节支具已被设计、制造并在两名患者身上进行了测试。该支具允许膝关节进行全范围运动，并在正常、非不稳定的步行速度下，将胫骨从接近完全伸展到中立位的角速度降低。它具备为每个患者以及同一患者康复期间调整终末角速度的功能。
