• iANG: initial angle of endpoint deviation (°); Area: area under the curve (m2); Time: time taken to reach the targets (s); fERR: final error, arc sign (m). Target 1: 90° glenohumeral ABD, elbow extended; Target 2: 90° glenohumeral ABD and 90° glenohumeral ER; Target 3: 120° scaption; Target 4: 120° glenohumeral flexion.
• Mean difference: mean difference between baseline and experimental phase. Data are presented as mean difference (SEM).
• Significant Time effect and Time x Group effect, p<0.05, for iANG, Time and Area under the curve. No significant difference for fERR (Time effect: p = 0.226; and Time x Group effect: p = 0,33)
• *Significant increase of performance for controls compared to baseline, p < 0.05.
• †Significant decrease of performance compared to baseline, p < 0.05.
