Shoulder impingement and rotator cuff injuries often respond well to physical therapy exercises. The success of the exercise program will depend on an accurate clinical assessment and an evidence-based approach to prescribing appropriate interventions. Two expert physical therapists and clinical researchers published an excellent review on the rehabilitation of shoulder impingement syndrome and rotator cuff injuries in the British Journal of Sports Medicine.
Drs. Todd Ellenbecker and Ann Cools offer a well-detailed description of the literature behind range of motion limitations, scapular dyskinesis, and muscle balance. Both authors have published extensively in these areas of clinical research, giving them an excellent perspective at translating evidence into practice by sharing their expertise. Ellenbecker and Cools provide some unique exercises for restoring shoulder muscle balance, including the “external rotation oscillation” exercise using Thera-Band® tubing and a FlexBar®. Dr. Ellenbecker recently completed an EMG study on this exercise, finding moderate levels of infraspinatus muscle activation. Another exercise researched by Dr. Ellenbecker, a 90-90 plyometric external rotation with a Thera-Band soft weight was highlighted in the article as well, and was featured previously on the Academy blog.

EMG evidence helps support evidence-based practice with Thera-Band

Electromyography (EMG) is a helpful tool for clinicians to decide which exercise would be best for their patients rehabilitation. Many studies have investigated the muscle activation levels of elastic resistance, including Thera-Band® resistance bands. Dr. Todd Ellenbecker of Physiotherapy Associates in Scottsdale, Arizona, investigated the EMG levels of 2 Thera-Band exercises he uses in his clinic. “We use these exercises on our patients, yet we don’t exactly know the muscle activation levels,” Dr. Ellenbecker noted, “EMG testing will help us make better clinical decisions for exercise prescription.”
Dr. Ellenbecker presented his findings at the 2010 Thera-Band Research Advisory Committee (TRAC) meeting. 21 subjects performed an external rotation oscillation with the FlexBar® exerciser and a Thera-Band Band Loop Wall Walk. The researchers measured surface EMG levels of the deltoid, rotator cuff and scapular stabilizers. Interestingly, both exercises produced similar levels of activation. The most active muscle for both exercises was the infraspinatus of the rotator cuff, which had moderate activation levels. Interestingly, the ratios of the upper trapezius to lower trapezius were over 1:1 for both exercises. “That’s important because we like to bias the lower trapezius, which is usually weaker than the upper trapezius in shoulder patients,” said Dr. Ellenbecker.

Upper Extremity Plyometrics for Tennis Players

Application of Upper Extremity Plyometrics for Rehabilitation and Performance Enhancement in Elite Tennis Players

High level tennis play requires repetitive activation of the rotator cuff and scapular musculature to stabilize, accelerate, and decelerate the glenohumeral joint to prevent injury and allow for optimal performance. The modern game of tennis is highly dominated by serves and forehands. Some estimates report that 75% of all shots by elite level players are forehands and serves. Serves and forehands are characterized by powerful concentric internal rotation of the shoulder. Research performed on elite level tennis players with isokinetic testing has shown muscular imbalances due to selective development of the internal rotator muscles without concomitant development of the external rotators on the dominant “tennis playing” extremity. Additionally, research has not shown increases in posterior rotator cuff or scapular muscle strength following tennis play alone in elite players indicating the need for supplemental strengthening of the posterior rotator cuff and scapular musculature to improve muscle balance in the dominant shoulder of the elite tennis player. Exercises to improve muscle balance and local muscular endurance have been advocated to both prevent injury and enhance performance in tennis players.
