Brief summary (from the registry)
Background: Subacromial impingement syndrome (SIS) is a common shoulder disorder characterized by pain, altered movement patterns, and functional impairment. Forty-four to sixty-five percents of the patients with SIS would develop chronic symptoms. Chronic subacromial impingement syndrome (CSIS) is involved in the alteration of central nervous system, such as somatosensory dysfunction and corticomotor changes. The treatments for these patients usually focus on shoulder control and strengthening exercise but no treatment has been found to be targeted on the alterations in somatosensory dysfunction. Focal muscle vibration (FMV) is a useful tool to provide proprioceptive stimulation and has showed short-term effects of improving sensorimotor performance in both healthy and diseased individuals when combined with exercise. To our knowledge, no study has used FMV combined with shoulder exercise for individuals with shoulder problems. Purpose: To investigate the effects of FMV combined with exercise on somatosensory activity, corticomotor excitability, pain and function in individuals with CSIS. Methods: This is a randomized control trial. We will recruit ninety subjects with CSIS to receive a 12-session treatment protocol of FMV combined with shoulder exercises. The subjects will be randomized into a treatment group or control group. While the treatment group will receive 20-minute FMV when doing strength training, the control group will have the vibrators attached on but without being turned on during strength training. Both groups will have a 10-20 minutes of shoulder control training following the FMV protocol. The outcomes will be measured before and after the 12-session treatment protocol and include measures of somatosensory activity (using Electroencephalography, EEG), corticomotor excitability (using transcranial magnetic stimulation, TMS), pressure pain threshold, depression scale, pain intensity in a numerical rating scale, and shoulder function. The somatosens…
