The functional evaluation of the elbows (affected elbows vs. unaffected elbows)

Outcomes	Degrees (°)	F	P
Flexion of the affected elbows	145.26 ± 4.94 (136.0–157.0)	5.154	0.027
Flexion of the unaffected elbows	148.33 ± 5.01 (139.0–161.0)
Extension of the affected elbows	6.63 ± 4.83 (− 1.5–14.0)	2.642	0.110
Extension of the unaffected elbows	4.57 ± 4.45 (− 6.5–10.0)
ROM of the affected elbows	138.63 ± 5.95 (127.0–150.0)	10.045	0.003
ROM of the unaffected elbows	143.76 ± 5.95 (130.5–155.0)
