Change from baseline to three, six, and 12 months of follow up in Constant score and subscores among 84 consecutive patients with subacromial impingement

Constant’s shoulder score with subscores	Change in score		p Value
Constant’s shoulder score with subscores	Physiotherapy group	Surgery	p Value
Values are mean (95% confidence interval) by one way analysis of variance.
Constant’s shoulder score = sum of pain, function, range of movements, and force.
ADL, activities of daily living; VAS, visual analogue scale.
