Isometric strength and PFG (kg)

	Baseline		Week 6
Elbow	Healthy	Affected	Healthy	Affected
Wrist strength in extension	12 ± 5	12 ± 5	13* ± 5	13* ± 5
Wrist strength in flexion	39 ± 17	37 ± 19	40 ± 22	40 ± 22
PFG (extension position)a	30 ± 11	26a ± 14	33b ± 11	28ab ± 13
PFG (flexion position)	31 ± 11	29 ± 13	34b ± 12	31b ± 14

Mean ± standard deviation

^*Significant increase of the score from baseline (main effect of time, P = 0.022)

^aPFG significantly lower than the measure with the elbow in flexion and the healthy elbows (interaction elbow status-position, P = 0.011)

^bPFG significantly higher than the score from baseline (main effect of time, P = 0.021)
