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