Pain is a common symptom associated with musculoskeletal conditions. This study
examined if pain resulting from a unilateral upper extremity musculoskeletal
injury compromises the person's ability to rapidly initiate and release handgrip.
METHODS: Delays in initiating and releasing a handgrip were determined for 28
individuals with "low pain" and 12 individuals with "high pain" in the injured
upper extremity. All participants had no pain in the uninjured upper extremity.
RESULTS: The high-pain group was 10% slower in initiating and releasing a grip
than the low-pain group, in both injured and uninjured upper extremities, for
both maximal and submaximal grips. In addition, delay in grip initiation was, on
average, 8% longer for the injured than for the uninjured upper extremity.
CONCLUSIONS: Unilateral musculoskeletal pain appears to delay grip initiation and
relaxation bilaterally, perhaps due to a centrally mediated mechanism. LEVEL OF
EVIDENCE: n/a.
