Wrist and hand
sensori-motor impairment have been observed after distal radius fracture (DRF)
treatment. This impairment and its relationship to function lack research.
The primary aim of this exploratory study was to determine
the magnitude of wrist and hand sensori-motor impairment following surgical and
non-surgical treatment among older patients following DRF. Secondary aims were to
determine the relationship between wrist and hand sensori-motor impairment with
function and pain as well as the relationships among wrist and hand sensori-motor
impairment and function and age following DRF. METHODS: Ten Test (TT), active
joint position sense (JPS), electromyography (EMG), computerized hand-grip
dynamometer (CHD), and the Patient-Rated Wrist Evaluation (PRWE) were used to
assess twenty-four female participants 8 weeks following DRF treatment and their
24 matched-control healthy counterparts on wrist and hand sensibility,
proprioception, muscle recruitment, grip force, muscle fatigue, and functional
status. RESULTS: Participants following DRF demonstrated significantly (p < .05)
greater sensory (i.e., JPS, TT), and motor (i.e., EMG, CHD) deficits than their
control counterparts. A significantly higher functional deficit (i.e., PRWE) also
existed among participants following DRF than the control group. Participants
following surgical and non-surgical DRF treatment were found to be statistically
different only on total grip force. Group differences on JPS and total grip force
revealed the strongest effect size with the highest correlations to PRWE. EMG and
muscle fatigue ratio group differences revealed a weaker effect size with a fair
degree of correlation to PRWE. Pain significantly correlated with sensori-motor
function. Age did not correlate with any measured variable. CONCLUSIONS:
Significant wrist and hand sensori-motor impairment and functional deficits among
older females 8 weeks following DRF surgical and non-surgical interventions were
revealed. JPS and total grip force were the most clinically meaningful tests for
assessing the sensori-motor status as well as explaining functional disability
and pain levels for these patients. LEVEL OF EVIDENCE: 2c.
