The purpose of this study was to determine the remote after-effects (RAE) of a resistive static contraction of the pelvic depressors (RSCPD) using a Proprioceptive Neuromuscular Facilitation (PNF) pattern in the mid-range of pelvic motion in side-lying as an indirect approach on the improvement of hand-behind-back (HBB) range of motion (ROM) in patients with rotator cuff tears. A static stretch (SS) group and hold-relax (HR) group were used for comparison to the RSCPD group. Twelve outpatients with symptomatic rotator cuff tears were randomly assigned to the RSCPD group, HR group, or SS group. The mean (SD) age was 68.8 (6.2) years (range: 34-81). HBB ROM determined by measuring the distance between the top of the thumb and the spinous process of C7 (TSD) in centimeters was assessed with a tape. Percentage change in TSD after each technique was calculated in comparison with TSD before the technique. Group means were compared using a one-way analysis of variance (ANOVA) with Scheffé's test. The results of a one-way ANOVA showed significant differences between the techniques. Scheffé's post hoc testing revealed a significant difference only between the RSCPD group and SS group (p<0.05), sreflecting a greater percentage change in TSD in the RSCPD group. Application of RSCPD technique may be an effective approach in indirectly treating extremities that cannot be exercised directly because of pain. RAE of RSCPD technique may improve the AROM of the shoulder joint in patients with rotator cuff tears.
