The correlation of cognitive capacity with recovery of hand sensibility after peripheral nerve injury of upper extremity.

INTRODUCTION

The aim of this study is to determine the correlation of cognitive ability with functional sensibility.

METHOD: 130 patients with median and ulnar nerve repair at the distal forearm level and wrist level were included. Mean time since surgery and age were 44.35 months (range 23-68) and, 33.44 years (range 18-71), respectively. The patients underwent an assessment of sensory function of the hand and a battery of specific tests for cognitive capacity.

RESULTS

A multiple linear regression analysis demonstrated a significant correlation between functional sensibility and cognitive capacity [Block design test (Beta=0.40, p=0.00); Reaction time (Beta=-0.32, p=0.00); The Stroop color word test (Beta=0.16, p=0.04)].

DISCUSSION: The results suggested that, cognitive capacity factors are associated with functional sensibility after nerve repair. These results may be mentioned cognitive rehabilitation programs would enhanced functional outcome following nerve repair.
