Abstract.[Purpose] The aim of the study was to evaluate the effect of an intervention, including shoulder control and strengthening exercises, on the shoulder function of persons with shoulder impingement.[Subjects] The subjects were patients who visited our hospital due to shoulder impingement syndrome and they were randomly allocated to two groups: a shoulder control and strengthening exercises group (n=17) and a conservative therapy group (n=18).[Methods] Both groups received conservative therapy for 3 sessions (45 minutes per week) for 4 weeks. The shoulder control and strengthening exercises group practiced additional motor control and strengthening exercises for 30 minutes. Values of the pain, function, isokinetic strength and the range of motion were compared with those of the conservative therapy group.[Results] There were significant differences in the amount of change of the pain, function, isokinetic strength and range of motion between the two groups (p<0.05); however as a measure of isokinetic strength, the peak torque of the internal rotators at 60°/sec did not show a significant difference.[Conclusion] The motor control and strengthening exercise program training improved pain, function, strength and the range of motion. These results suggest that a motor control and strengthening exercise program is feasible and suitable for individuals with shoulder impingement syndrome.

“…The extrinsic theory (extratendinous) asserts that impingement occurs due to factors external to the tendon. These include faulty posture, acromial morphology, posterior capsular tightness, instability, and altered scapular or glenohumeral kinematics (Mattiello-Rosa et al, 2008).…”

ABSTRACT. The aim of this study was to review the literature evaluating the effect of isokinetic training in patients suffering from shoulder impingement syndrome (SIS). Studies published up to March 2011 were located from the Pubmed, Scopus, Lilacs, Physiotherapy Evidence Database, and Cochrane Library databases using "isokinetic", "shoulder", and "impingement" as key words. Referenced studies were also checked. Studies were included if isokinetic training was employed as at least one of the treatments in the therapeutic program to treat shoulder impingement or other shoulder pathologies leading to impingement-related pain. All eligible studies described the level of evidence, patient characteristics, interventions, outcome evaluation, results, complications, and return to work. There were 2 randomized control trials (RCTs) and 4 studies with level 4 evidence that met the inclusion criteria. All of the studies included showed a statistically or clinically significant outcome after isokinetic training. However, most of the studies could not identify the isolated effect of isokinetic training. There was not enough evidence to support or refute the effectiveness of isokinetic training for SIS. This result does not reflect a true lack 745 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 13 (1): 744-757 (2014) Isokinetic training on shoulder impingement of effect, but rather a lack of RCTs. A consensus definition of the different types and stages of SIS is urgently needed. More RCTs are also essential to clarify the value of this technique. The homogeneity of treatment interventions, study populations, and outcome measures should be prioritized. Further studies are also needed to clarify the differences in isokinetic data across different types and stages of shoulder impingement.

“…Studies suggest that proper dynamic function of shoulder stabilization muscles, especially the rotator cuff, can be a determinant factor in the prevention and/or severity of the lesions to skeletal muscle tissue [15]. In the past few years there has been an increase in the use of stem cells in the treatment of degenerative diseases.…”

Rotator cuff tears occur mainly due to overload of the tendons, which leads to a progressive degenerative process and to rotator cuff tears. Surgical treatment is indicated in more advanced stages of the lesion. Retear affects approximately 35% of patients. The goal of the present study was to investigate the effect of mononuclear cell transplantation in rotator cuff repairs in relation to patient functional recovery. Thirty patients with rotator cuff tear were divided into two groups and submitted to rotator cuff repair. In addition to the surgical procedure, the experimental group was submitted to transplantation of mononuclear bone marrow cells. One to two years post-op, both groups were submitted to evaluation of pain, amplitude of movement, retears, and isokinetic evaluation of flexion-extension movements, external and internal rotations, and abduction and adduction of the shoulder. The operated shoulder was compared to the healthy shoulder. Mann-Whitney test was used to evaluate the percentage improvement of the operated shoulder in relation to the healthy shoulder. SPSS (13.0) was used for statistical analyses; the level of significance was p<0.05. The control and the experimental groups presented near-normal values for the variables analyzed in the comparison between shoulders. However, the experimental group showed better results than the control group. Functional recovery of patients submitted to repair with mononuclear cell transplantation was different than that of controls: the incidence of retear was lower in the experimental group; also, the muscle torque and balance values were closer to the healthy shoulder values for the experimental group than the controls.
