Motor imagery performance and tactile acuity in patients with complaints of arms, neck and shoulder.

Aim: This study aims to gain more knowledge of the sensorimotor incongruence in patients with chronic nonspecific complaints of arm, neck and shoulder.

Method: Seven patients and seven healthy controls performed a left/right judgment task, and tactile acuity was assessed by the two-point discrimination threshold at fingers and shoulders.

Results & Conclusion: The results suggest a decreased tactile acuity in patients with chronic nonspecific complaints of arm, neck and shoulder and a faster reaction time at the painful arm, which might imply disturbed information processing of sensory and motor feedback.
