Table 4. Durations of Symptoms Related to Range of Motion.

Kruskal-Wallis Test used.

Duration of Symptoms (Months)	≤3	4–6	7–12	>12	p-value
Elevation	115(160)180	140(160)180	130(170)180	142(170)180	*0.032*
Extension	30(30)50	30(40)60	30(30)40	30(40)50	0.26
Abduction	60(80)90	70(80)90	70(80)90	70(80)90	0.22
Adduction	30(30)50	30(40)60	30(40)60	30(30)60	0.095
External Rotation in Adduction	40(60)60	40(60)60	42(60)60	40(60)60	0.24
Internal Rotation in Adduction	60(60)60	60(60)60	60(60)60	60(60)60	0.13
External Rotation in Abduction	60(80)90	70(80)90	70(80)90	70(90)90	0.76
Internal Rotation in Abduction	20(50)60	20(40)68	30(50)60	30(30)60	0.79

A(B)C – A=lower quartile, B= median. C=upper quartile. Rotations were measured with arm at side (adduction) or at 90 degrees of abduction (abduction). The only statistically significant finding was found to affect those who had symptoms for 7 months or more, who had 10 degrees more forward elevation.
