  1. The data represent Spearman's rank correlation coefficient. Correlation coefficients between the number of muscles with myofascial trigger points (MTrPs), the number of muscles with active MTrPs (AMTrPs) and the number of muscles with latent MTrPs (LMTrPs), the DASH (Disability of the Arm, Shoulder and Hand) outcome measure- Dutch Language Version (DASH-DLV), the Beck Depression Inventory-second version- Dutch language Version (BDI-II-DLV), the Visual Analogue Scales for current pain (VAS-P1), the average pain over the last seven days (VAS-P2), the most severe pain over the last seven days (VAS-P3) and the duration of shoulder pain (Duration), are given (* p < 0.05).
