Relationship among grip strength, functional outcomes, and work performance following hand trauma

: This study examined the relationship among the recovery grip strength, functional outcomes, and work performance following occupational therapy intervention for hand trauma. This study had a sample size of 15 participants whose recovery grip strength was measured using a Jamar dynamometer, whose satisfaction with outcomes was measured by the Michigan Hand Outcomes Questionnaire (MHQ), and whose compliance with the home therapy program was measured by a visual analog scale (VAS). A Pearson r correlation demonstrated a significant relationship between recovery grip strength and two MHQ subset scores: overall hand function (r = 0.59, p = 0.019) and activities of daily living (ADL) performance (r = 0.61, p = 0.016). The participants' self-rating of compliance did not predict or influence either recovery grip strength or MHQ scores. A moderate positive correlation approaching significance (r = 0.51, p = 0.052) was found between grip strength and overall MHQ scores. The researchers concluded that a recovery grip strength measure should be used along with functional measures to appropriately assess overall hand function following hand trauma.
