Handgrip strength of the elderly after hip fracture repair correlates with functional outcome.
OBJECTIVE
To investigate the relationship between handgrip strength (HG) and upper limb functioning of hip fracture operated elderly patients and their functional outcome 6 months post-op.


METHODS
Retrospectively, data on 105 post-operative hip fracture patients was analyzed. Functional level was measured by the Functional Independence Measure (FIM) and HG by hand dynamometer, 7-10 days, 1, 3 and 6 months post-op. FIM1 up-to FIM4 (FIM1-FIM4) and HG1 up-to HG4 (HG1-HG4) were determined. Pre-fracture upper limb function was evaluated using the disabilities of the arm, shoulder and hand (DASH) questionnaire. The Mini-Mental-State Examination evaluated cognition.


RESULTS
FIM1-FIM4 scores increased during the 6-month follow-up; HG1-HG4 scores remained unchanged. No differences were found in FIM1-FIM4 and DASH scores between genders. HG1-HG4 scores were significantly higher in men (p = 0.04-0.005). FIM1-FIM4, HG1-HG4 and DASH scores were higher in the cognitively normal patients (p < 0.001). A fair correlation was found between all HG and FIM scores (R = 0.36-0.71, p < 0.001), and between DASH and FIM scores (R = 0.5-0.7, p < 0.001). Log HG1 and FIM4 scores were highly correlated (R(2) = 0.54, p < 0.001). Regression analysis found that only, and in the following order were Log HG1, FIM1, DASH and age significant factors affect FIM4 score (R(2) = 0.69).


CONCLUSIONS
HG and FIM scores, a week post-op., combined with upper limb functioning and age, can have a 69% prediction accuracy for motor functioning 6 months post-fracture. HG measurement, a week post-hip fracture repair, might be considered in estimating functional motor outcome, and eventually additional interventions should be employed to increase muscle strength and, thus, improve functional outcome.
