Statistical analysis of differences between the affected and the contralateral unaffected arm

Range‐of‐movement measure	Affected arm	Unaffected arm	P value (Kolmogorov‐Smirnov test)	t value	P value
Extension deficit	21.25 ± 11.88	0.63 ± 4.17	0.2363	5.74	0.0007
Flexion	126.88 ± 8.43	139.00 ± 2.07	0.0027	–	0.0078
Arc of motion	105.63 ± 20.08	138.38 ± 7.29	0.0610	–	0.0078
Pronation	71.25 ± 18.66	86.50 ± 2.20	0.0079	–	0.0156
Supination	75.00 ± 14.64	86.25 ± 2.6	0.0233	–	0.0313

Each data set was assessed with the Kolmogorov‐Smirnov test of normality to permit use of the t‐test. Where P < 0.1, the non‐parametric test was used, so there are no t‐test values in the last four rows.
