Eccentric training for shoulder abductors improves pain, function and isokinetic performance in subjects with shoulder impingement syndrome: a case series

Shoulder External Rotator Eccentric Training Versus General Shoulder Exercise for Subacromial Pain Syndrome: A Randomized Controlled Trial

“…8,11 Eccentric training of shoulder musculature as an intervention for the management of SAPS has been examined in six published clinical trials to date. [12][13][14][15][16][17] The authors of these investigations have utilized a variety of training protocols, specific exercises, dosing strategies, experimental and non-experimental methodology. None of these investigations have targeted the external rotators in isolation but rather the shoulder abductors alone or in combination with the external rotators.…”

“…20 The effects of eccentric training, of only the shoulder external rotators, in patients experiencing SAPS has not been studied in a randomized controlled trial. Moreover, limitations due to single arm designs, [14][15][16] a focus on eccentric loading of the shoulder abductors, 12,13 or a lack of appropriate load for the provided eccentric exercises 17 warrants further study of eccentric training to the shoulder external rotators.…”

The Impact of Adding an Eccentric-Exercise Component to the Rehabilitation Program of Patients With Shoulder Impingement: A Critically Appraised Topic

“…7 The changes that occur as a result of eccentric exercises may improve function, strength, and performance and decrease pain more than concentric programs, producing better patient outcomes. 8,9 Although eccentric strength training has been shown to provide strength gains, 8,10 there are no clear guidelines as to the inclusion of this form of exercise training in shoulder rehabilitation programs for the purposes of improving function and decreasing pain.…”

Fortalecimiento excéntrico en tendinopatías del manguito de los rotadores asociadas a pinzamiento subacromial. Evidencia actual

“…Camargo et al 27 reportaron una serie de casos que tuvo céntrico para los abductores de hombro en relación con el dolor, el estado físico-funcional y el desempeño isocinético durante la abducción excéntrica en sujetos con síndrome de pinzamiento subacromial. Se incluyó a 20 pacientes, con duración promedio de dolor de 2.8 ± 2.9 años.…”

“…Sin embargo, la evaluación 4 mostró valores menores comparados con la evaluación 1 (p < 0.01), 2 (p = 0.02) y 3 (p = 0.02); de la misma forma, el pico de torque, el después de la intervención (p < 0.05). Este estudio indica que el entrenamiento isocinético con ejercicio excéntrico para abductores de hombro mejora la función física de la extremidad superior en pacientes con síndrome de pinzamiento subacromial 27 . Maenhout et al 28 publicaron hasta ahora el único ensayo clínico aleatorizado controlado, en el que incluyeron a 61 pacientes con diagnóstico de pinzamiento subacromial y, de forma aleatoria, se dividieron en 2 grupos: uno control, con tratamiento conservador para pinzamiento subacromial (n = 30, media de edad de 39.4 ± 13.1 años), y un grupo experimental, que incluía tratamiento convencional y entrenamiento excéntrico (n = 31, media de edad de 40.2 ± 12.9 años).…”
