Brief Summary

Rotator cuff tendinopathy (RCT) is regarded as a common and burdensome source of shoulder pain with prevalence estimated to be as high as 14% in general working-age population. RCT is a broad entity, including a vast variety of diagnosis such as shoulder impingement syndrome, RC tendinitis/tendinosis, as well as subacromial bursitis. The course of RCT is characterised by persistent pain and/or disability and/or recurrent episodes. It often leads to decrease function, lower health-related quality of life, poor sleep quality, work absenteeism, as well as patient's suffering. Previous studies support exercise as an adequate treatment in RCT. Nevertheless, our knowledge, there is no studies evaluating the effects of isoinertial training in RCT. Therefore, the aim of this study will be to pilot the methods proposed to conduct a substantive study to evaluate the efficacy of isoinertial training plus eccentric training versus eccentric training alone on improving pain and function in RCT. The objectives were to evaluate: (i) The process of recruitment and retention rates; (ii) Willingness of participants to be randomised; (iii) The extent of contamination between groups; (iv) Participant adherence with treatment. The secondary aim will be to analyse the effects of isoinertial training plus eccentric training versus eccentric training alone on rotator cuff strength, scapular muscle activity, and scapular muscle endurance in people with RCT.

Study Arms (2)

Isoinertial + eccentric exercise

EXPERIMENTAL

The isoinertial training will be based on 4 sets of 8 maximal repetitions using a YoYo-Squat (YoYo Technology AB, Stockholm, Sweden). This exercise device use the inertia of a spinning flywheel (moment inertia = 0.11 kg m-2), offering resistance during coupled concentric and eccentric actions, and allows for high demanding to rotator cuff exercises while offering the possibility to perform with an eccentric overload.Two initial repetitions in any set were aimed at accelerating the flywheel, before executing the subsequent 8 actions at maximal effort. Eccentric exercise will based on a set of 4 exercise implicating abduction, lateral rotation, extension and flexion of the shoulder.

Other: Isoinertial + eccentric exercise

Eccentric exercise

ACTIVE COMPARATOR

Eccentric exercise will based on a set of 4 exercise implicating abduction, lateral rotation, extension and flexion of the shoulder. Participants will attend three appointments per week over three weeks. They will complete three sets of 10 repetitions, with the exercises progressed in difficulty at each appointment.

Other: Eccentric exercise

Interventions

A session of isionertial + eccentric exercise covers the activity, strength and endurance of scapular muscles.

Isoinertial + eccentric exercise

A session of eccentric exercise covers the strength of scapular muscles.
