Study	Sample	Procedure	Findings
Draak et al.	International adults (n=163) with immune mediated neuropathies undergoing intra-venous immunoglobulin & other medical interventions	Dynamometer: Jamar in second handle position. Grip measurement times: baseline & retests 1, 3, 6, 12 mo post-baseline Anchor: General rating of health “compared to one year ago” (5 category from SF-36). Criterion: “somewhat better”	Mean difference (increase) at 6 mo: about 67% MCID: 2.7 kg
Kierkegaard et al.	Canadian adults (n=108) with myotonic dystrophy	Dynamometer: Jamar Grip measurement times: baseline and retest (9 yrs). Anchor: Patient rating of hand weakness (5 category). Criterion: “worse”	Median difference (decrease) at 9 yrs: 1 kg, 13.3%. MCID: 0.04 kg (AUC 0.51), 0.8% (AUC 0.58)
Kim et al.	Korean adults (n=50) undergoing surgical repair of distal radius fracture	Dynamometer: Jamar Grip measurement time: 1 yr post surgery Anchor: Rating of strength compared to before injury (4 category) Criterion = “weakened”	Mean difference (decresase) injured vs. calculated preinjury: 5.0 kg, 17.9%. MCID: 6.5 kg (AUC 0.76), 19.5% (AUC 0.77)
Lang et al.	American adults with recent stroke (n=52)	Dynamometer: Jamar in 3rd handle position. Grip measurement times: baseline (9.5 d) and retest (25.9 d) post-stroke Anchor: Global rating of change (7 category). Criterion = “a little better, meaningful.”	Mean difference (increase) over time (affected side): 6.9 kg, 71.9%. MCID: 5.0 kg (dominant side affected), 6.2 kg (nondominant side affected)
