Strength measured in Newton presented as mean and standard deviations (SD) for normally distributed values. If not normally distributed data is presented as median, 25^th and 75^th percentiles (external rotation). Pain reported on a visual analogue scale presented as median and 25^th and 75^th percentiles. CI Confidence interval. * indicates significant difference
