Rehabilitation of hemiplegic upper extremity shows multiple problems. In these complications, peripheral neuropathy is one of the important complications that influence prognosis of hemiplegic upper extremity function.

The subjects of this study were 27 cases with stroke who were admitted to Kyung Hee Medical Center & received electrodiagnostic examination from March 1, 1989 to September 30, 1989.

The result is as follows:

1) In 27 examined stroke patients, 15 cases (55.6%) have peripheral neuropathies, and average duration from onset to electrodiagnostic study was 7±8.58 months in normal group, & 9.67±18.48 months in group combined with periphesal neuropathy.

Then, th incidence of periphesal neuropathy is poorly correlated with duration from onset to electrodiagnostic study(p>1).

2) According to Mental state at onset, 25% in alert cases, 66.7% in drowsy cases, 60% in stuporous cases & 100% in semicoma cases showed peripheral neuropathies.

3) According to motor power in hemiplegic upper extremity, 68.8% in zero group & 50% in trace group showed peripheral ueuropathies, but 3 cases in poor group were normal.

4) According to degree of spasticity at study, peripheral neuropathies were showed in 70% in zero group, 100% in Trace group, 41.7% in One Positive group & 33.3% in Two Positive group.

5) The 6 cases without subluxation of hemiplegic shoulder showed all normal, and 8 Cases with subluxation more than 1 finger showed peripheral neuropathies in all cases.
