Current clinical practice lacks consistent evidence in the management of scapular dyskinesis. This study aims to determine the short- and long-term effects of a scapular-focused exercise protocol facilitated by real-time electromyographic biofeedback (EMGBF) on pain and function, in individuals with rotator cuff related pain syndrome (RCS) and anterior shoulder instability (ASI). One-hundred and eighty-three patients were divided into two groups (n = 117 RCS and n = 66 ASI) and guided through a structured exercise protocol, focusing on scapular dynamic control. Values of pain and function (shoulder pain and disability index (SPADI) questionnaire, complemented by the numeric pain rating scale (NPRS) and disabilities of the arm, shoulder, and hand (DASH) questionnaire) were assessed at the initial, 4-week, and 2-year follow-up and compared within and between. There were significant differences in pain and function improvement between the initial and 4-week assessments. There were no differences in the values of DASH 1st part and SPADI between the 4-week and 2-year follow-up. There were no differences between groups at the baseline and long-term, except for DASH 1st part and SPADI (p < 0.05). Only 29 patients (15.8%) had a recurrence episode at follow-up. These results provide valuable information on the positive results of the protocol in the short- and long-term. Full article

Background and Objectives; Proprioceptive neuromuscular facilitation (PNF) are effective in improving and maintaining Range of motion(ROM), increasing muscular strength and power, and increasing athletic performance, especially after exercise. The scapula patterns defined in PNF are activated within the upper extremity patterns and scapula motions together. Proper function of the upper extremities requires both motion and stability of the scapula. The purpose of this study was to compare the effects of scapula stabilization exercise training involving muscle strengthening, muscle balance, and movement control exercises on office workers with scapula dysfunction. Materials and Methods: A total of 42 office workers with scapula dyskinesis were recruited and randomly divided into three groups: muscle strengthening exercise group (n = 14), muscle balance exercise group (n = 14), and movement control exercise group (n = 14). The participants underwent 18 sessions (25 min/session, 3 days a week for 6 weeks) of training involving the three types of exercises. Results: The measurement outcomes included the scapula index, measured using a digital Vernier caliper; scapula function, evaluated using the Disability of the Arm, Shoulder, and Hand (DASH) outcome questionnaire (pain and performing, work ability, and sports and art activities); and scapulohumeral movements (scapula upward rotation at humeral abduction angles of 0°, 45°, 90°, 135°, and 180°), evaluated using inclinometers. After the exercise intervention, the scapula index (p = 0.002), DASH pain and performing score (p = 0.000), DASH work ability score (p = 0.000), DASH sports and art activity score (p = 0.027), and scapulohumeral movements (scapula upward rotation at 0° (p = 0.013) and 45° (p = 0.043) humeral abduction) showed significantly greater improvements in the movement control group than in the muscle strengthening and muscle balance groups. Conclusions: Thus, proprioceptive neuromuscular facilitation can be used as a rehabilitation intervention for scapula position and movement, pain reduction, and functional improvement in office workers with scapula dyskinesis.
