Abstract:

BACKGROUND: Limb exoskeletons rehabilitation robots can stimulate the natural resilience of body through simulated human movement to achieve tissue compensation based on its theoretical basis of continued combined active and passive activities. 
OBJECTIVE: To dynamically observe and realize the rehabilitation effect of limb exoskeletons rehabilitation robots on functional exercise of patients with activity limited knee joint.
METHODS: Twenty early postoperative patients with activity limited knee joint were divided into experiment group and control group randomly. The functional exercise with limb exoskeletons rehabilitation robots was performed in the experiment group. The control group underwent functional exercise with passive training devices CPM. Psychological guide, low-frequency pulse electrotherapy and infrared physiotherapy were performed in both groups during the treatment.
RESULTS AND CONCLUSION: The active degree of retroflexion and protrusive movement of knee joint in all cases was improved. The muscle strength of the quadriceps femoris in experiment group was significantly improved after treatment (P < 0.01). The active degree of retroflexion and protrusive movement of knee joint in experiment group was further improved after 2 months follow-up treatment (P < 0.01). The indexes above did not change in control group. The results showed that the application of limb exoskeletons rehabilitation robots or passive training devices CPM combined with psychological guide, low-frequency pulse electrotherapy and infrared physiotherapy both could significantly improve the active degree of retroflexion and protrusive movement of knee joint in patients with activity limited knee joint, at the same time, the limb exoskeletons rehabilitation robots could recover the muscle strength of the quadriceps femoris.
