To investigate the effect of task oriented training on the hand functional disorders after peripheral nerve injury, in order to offer a new kind of rehabilitation treatment.

Sixty cases of the hand functional recovery after peripheral nerve injury were divided into the treatment group (30 cases) and the control group (30 cases) on the basis of the random number table method. Two groups of cases received drug therapy and routine rehabilitation therapy, the treatment group with task orientation training. The hand function assessment scale was measured before and after 3 months treatment in order to evaluate the hand function, the electromyography were examed to evaluate peripheral nerve recovery.

After 3 months intervention, the total effective rate in the treatment group was obviously higher than the control group (P<0.05). After 3 months intervention, the median nerve MCV, ulnar nerve MCV, radial nerve MCV in the treatment group were obviously higher than that of before treatment, as well as the radial nerve MCV singnificantly higher than control group (P<0.05), the median nerve MCV, ulnar nerve MCV, radial nerve MCV in the control group were significantly higher than that of before treatment (P<0.05). The median nerve LAT, ulnar nerve LAT, radial nerve LAT in the treatment group were obviously shorter than that of before treatment, the median nerve LAT, radial nerve LAT in the control group were significantly shorter than that of before treatment (P<0.05). The median nerve AMP, ulnar nerve AMP, radial nerve AMP in the treatment group were obviously higher than that of before treatment, meanwhile, the median nerve AMP and ulnar nerve AMP were singnificantly higher than control group (P<0.05), the median nerve AMP and radial nerve AMP in the control group were significantly higher than that of before treatment (P<0.05).

The task orientation training can significantly improve neuromuscular excitability of patients with the hand functional disorders after peripheral nerve injury, as well as improve the hand function. The task of design orientation training is a safe, practical and effective training program which combines a variety of sensory stimulation and daily life activities.
