“…2,16,24 A systematic review demonstrated the effect of isokinetic training; however, most of the studies could not identify the isolated effect of isokinetic training. 26 In isokinetic exercise training, there is no established protocol for angular velocity. When considering the EMG(IS)/tWK ratio, isokinetic exercise at 180 deg/s seemed to be most effective in inducing higher IS muscle activation per unit of work.…”

Background: Isotonic exercise is commonly adopted for shoulder rehabilitation, but the efficacy of isokinetic exercise for rehabilitation has not been evaluated. Purpose: To evaluate the efficacy of isotonic and isokinetic external shoulder rotation exercises. Study Design: Controlled laboratory study. Methods: Using surface electromyography (EMG) and the Biodex system, we investigated the EMG amplitude of the infraspinatus (IS), total work (tWK), and EMG(IS)/tWK ratio and examined the relative IS and posterior deltoid (PD) contributions to all exercises. A total of 24 healthy participants without musculoskeletal injuries were included. Participants performed isotonic external shoulder rotation at 10%, 20%, 30%, 40%, and 50% of the maximum voluntary isometric contraction (MVIC) as well as isokinetic external shoulder rotation at angular velocities of 60, 120, 180, 240, and 300 deg/s. Levels of intensity were classified from 1 to 5: level 1 corresponded to 10% of the MVIC and a 300-deg/s angular velocity; level 2 corresponded to 20% MVIC and 240 deg/s; level 3 corresponded to 30% MVIC and 180 deg/s; level 4 corresponded to 40% MVIC and 120 deg/s; and level 5 corresponded to 50% MVIC and 60 deg/s. Normalized IS and tWK amplitudes were calculated for each exercise. Results: During isotonic exercise, the EMG(IS)/tWK ratio significantly decreased from level 5 to 3, 2, and 1; from level 4 to 2 and 1; and from level 3 to 1. During isokinetic exercise, the EMG(IS)/tWK ratio at level 3 was greater than that at all other levels except level 1. Statistical differences were found between isotonic and isokinetic modes at levels 1, 2, and 3. The IS/PD activation ratios were not significantly different between exercise modes at any level. Conclusion: Isokinetic resistance may provide more effective stimulation of the IS muscle compared with isotonic resistance. Clinical Relevance: Isokinetic exercise needs to be considered as a method of rehabilitation that effectively increases infraspinatus muscle activity.

“…Two were of high quality, 4,46 1 was of acceptable quality, 47 and the last was of low quality. 45 The first SR 4 reviewed trials that compared surgical techniques targeting release of shoulder impingement with any type of conservative treatment including physical training, education, and passive physiotherapy, or comparable treatment. Seven RCTs were considered to fulfill the inclusion criteria of the SR.…”

“…Therefore, they reported that there was not enough evidence to support or refute the effectiveness of isokinetic training for SIS because of the lack of evidence. 45 Only 1 SR assessed safety and adverse events of the individual studies included. 47 They found that 8 of 11 RCTs reported on adverse events and that none of these observed any serious adverse events.…”

Objective: The purpose of this review was to evaluate the effectiveness of conservative nondrug, nonsurgical interventions, either alone or in combination, for conditions of the shoulder. Methods: The review was conducted from March 2016 to November 2016 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and was registered with PROSPERO. Eligibility criteria included randomized controlled trials (RCTs), systematic reviews, or meta-analyses studying adult patients with a shoulder diagnosis. Interventions qualified if they did not involve prescription medication or surgical procedures, although these could be used in the comparison group or groups. At least 2 independent reviewers assessed the quality of each study using the Scottish Intercollegiate Guidelines Network checklists. Shoulder conditions addressed were shoulder impingement syndrome (SIS), rotator cuff-associated disorders (RCs), adhesive capsulitis (AC), and nonspecific shoulder pain. Results: Twenty-five systematic reviews and 44 RCTs met inclusion criteria. Low-to moderate-quality evidence supported the use of manual therapies for all 4 shoulder conditions. Exercise, particularly combined with physical therapy protocols, was beneficial for SIS and AC. For SIS, moderate evidence supported several passive modalities. For RC, physical therapy protocols were found beneficial but not superior to surgery in the long term. Moderate evidence supported extracorporeal shockwave therapy for calcific tendinitis RC. Low-level laser was the only modality for which there was moderate evidence supporting its use for all 4 conditions. Conclusion: The findings of this literature review may help inform practitioners who use conservative methods (eg, doctors of chiropractic, physical therapists, and other manual therapists) regarding the levels of evidence for modalities used for common shoulder conditions.

“…Shoulder pain is one of the most common complaints of the musculoskeletal system, with a lifetime prevalence estimated between 7 and 10%, and is most frequently caused by impingement syndromes and rotator cuff tears [ 1 , 2 ]. Other causes for shoulder pain should also be considered in the differential diagnosis [ 3 ], such as osteoarthritis, nerve irritation [ 4 ], instability, Parsonage–Turner syndrome [ 5 , 6 ], tumors, and conditions of inner organs [ 7 , 8 , 9 , 10 ], rheumatic diseases [ 11 ], alterations of local blood vessels [ 12 ], trauma, and osteonecrosis [ 13 ].…”

Shoulder pain is regularly associated with limited mobility and limitations in activities of daily living. In occupational therapy, various interventions, including active isokinetic training with a Baltimore Therapeutic Equipment (BTE) Work Simulator, help the patient improve shoulder mobility and alleviate pain. This randomized controlled cohort study aims to evaluate the impact of different isokinetic movement patterns on the DASH score, pain, and objective performance measures, such as range of motion (ROM) and hand grip strength. Patients that participated in a specific 3-week inpatient orthopedic rehabilitation were divided into two groups. The first group (UNI-group, n = 9) carried out uniplanar exercises for shoulder flexion, abduction, and external rotation. The patients in the second group (ADL-group, n = 10) imitated multiplanar everyday movements, such as climbing on a ladder, loading a shopping cart, and raising a glass to their mouth. Compared to the UNI-group, the ADL-group improved significantly in DASH scores (mean −10.92 ± 12.59 vs. −22.83 ± 11.31), pain (NPRS −1.11 ± 2.37 vs. 3.70 ± 2.00), and shoulder abduction (+2.77 ± 15.22 vs. +25.50 ± 21.66 degrees). In conclusion, the specific BTE exercise program with multiplanar movement patterns contributed considerably to the therapeutic improvement.
