Abstract:

Objective　To discuss the effects of ankle isokinetic muscle strength training on the balance function of elderly patients with stroke.　Methods　40 elderly patients with stroke were randomized into control group (n=20), the treatmentgroup (n=20). The control group received routine rehabilitation treatment. On the basis of the control group, the treatment group added the isokinetictraining on ankle dorsiflexion and plantarflexion muscle groups. Before the treatment, two groups were measured with the balance function related indicators, including Berg balance scale (BBS), Timed up and go test (TUGT) and the parameter from the Prokin balance instrument, such as Y-COP Standard Deviation, Sway length, Sway area, Peak torque measurement on ankle dorsiflexion and plantarflexion muscle group. Three weeks after training the same indicators were measured again.　Results　After balance training, the balance function of two groups improved significantly (P<0.05). Compared with control group, all indicators in muscle strength group were better(P<0.05).　Conclusions　Ankle joint isokinetic muscle strength training can significantly improve the balance function and themuscle strength of elderly patients with stroke.
