Abstract
In the anterior cruciate ligament (ACL) deficient or reconstructed knee populations, always have a problem of loss of proprioception in knee, and usually it may result in ACL recurrent injury or knee arthritis. The improvement of the peripheral proprioceptive sensory input of knee to compensate the loss of proprioception with ACL-deficient or reconstructed is an important topic to discuss.
The aim of first year is to develop a knee angle biofeedback motor control rehabilitation system (KABIS) for ACL-deficient or reconstructed patients to reinforce the peripheral proprioceptive sensory input. First, a knee angle biofeedback motor control rehabilitation system (KABIS) will be constructed, consisting of a self-made knee orthosis with an electric goniometer and a microcomputer-monitoring device attached to it. The electric goniometer will be constructed from two anatomically aligned metal stabilizers with a potentiometer at the hinge. The battery-powered microcomputer-monitoring unit will be mounted on a waist belt worn by the patients. The KABIS provides visual feedback whenever flexion and extension joint angle research the threshold goal set. The device can be set for 「feedback-on」 mode, in which visual feedback are on, or 「feedback-off」 mode, in which the device monitor and record down every motion that reach the threshold but does not provide visual feedback. The monitoring unit also enable the patients to adjust their knee under threshold. The recorded information can be easily
upload to a portable computer.
Similarly, total hip replacement patients always suffered from hip abductor weakness and proprioception deficit, caused by deficit of hip abductor and ligament of head of femur. The above problems would cause some complications such as
instability of joint and dislocation, an even more important cause of uneven weight bearing, poor balance and abnormal gait pattern. In order to reach functional activity, the recurrent dislocation will happen and the patients should receive
secondary surgery.
Several literatures indicated that hip abductor strengthening technique is a key strategy to improve the performance of muscle balance. The motor control training with an appropriate visual and auditory biofeedback could guide patients in reconstruct proprioception and enhance their motor relearning performance. Therefore, the aim of the second year is to develop a visual-audio biofeedback muscle strengthening and proprioception stimulation rehabilitation system for total hip replacement patients. The scope of work includes:(1) design of an instrumented hip angle measurement device;(2) development of a wireless transmission unit;(3)
design an visual-audio biofeedback training software for muscle strengthening and proprioception stimulation;(4) hardware and software system integration;(5) clinical assessment.
