“…The most frequently encountered outcome measure across studies was the Constant-Murley Score (CMS) [6,9,[11][12][13], with most studies showing a fair to high correlation between peak torque and overall shoulder function as measured by the 100-point CMS [40].…”

BACKGROUND: Shoulder pathology is common, particularly in older adults. This pathology often involves the muscles of the shoulder, particularly those of the rotator cuff. Although there are many procedures for measuring muscle weakness and imbalance of the shoulder rotator muscles, isokinetic dynamometry is probably considered the gold standard. OBJECTIVE: To describe the use and findings of isokinetic testing of the shoulder rotator muscles in patients with shoulder disorders. METHODS: A PubMed search was performed using the string "isokinet* AND rotator cuff." Thereafter, a secondary hand search was conducted. Original articles that reported isokinetic measures of the shoulder rotators in older patients with orthopedic shoulder disorders were identified, summarized, and critically appraised. RESULTS: Thirty-four relevant articles were found. The articles largely support the validity, reliability, and responsiveness of isokinetic strength measures of shoulder rotation strength in patients with shoulder pathology. CONCLUSIONS: The literature provides support for the isokinetic measurement of rotator muscle performance in patients with shoulder pathology. However, it is not always practical in the clinical setting.

“…Assessing muscular strength is important for strength and conditioning coaches, as well as for physical therapists, e.g., for evaluating performance [1], for injury prevention and to predict risk of injury [2], for evaluating musculoskeletal dysfunction [3][4][5], and in rehabilitation [6]. Testing of muscle strength is also used at workplaces, where physical capacity is assessed in relation to work capacity [7], and further, to evaluate physical exercise programs, musculoskeletal disorders, and dysfunctions [8].…”

“…Testing of muscle strength is also used at workplaces, where physical capacity is assessed in relation to work capacity [7], and further, to evaluate physical exercise programs, musculoskeletal disorders, and dysfunctions [8]. Muscle strength can be assessed in a number of ways, and is typically done so by using isokinetic or isometric testing devices, such as handheld-dynamometers [6,9,10], isokinetic dynamometers [1,2,4,[11][12][13][14][15], conventional strength training machines or equipment, such as dumbbells or barbells and weight plates [7]. Of the above, isokinetic or isometric dynamometers have been considered as gold standard in assessing muscle strength for a number of years by researchers [16][17][18][19].…”

Muscle strength assessment is fundamental to track the progress of performance and prescribe correct exercise intensity. In field settings, simple tests are preferred. This study develops equations to estimate maximal muscle strength in upper- and lower-extremity muscles based on submaximal elastic resistance tests. Healthy adults (n = 26) performed a maximal test (1 RM) to validate the ability of the subsequent submaximal tests to determine maximal muscle strength, with elastic bands. Using a within-group repeated measures design, three submaximal tests of 40%, 60%, and 80% during (1) shoulder abduction, (2) shoulder external rotation, (3) hip adduction, and (4) prone knee flexion were performed. The association between number of repetitions and relative intensity was modeled with both 1st and 2nd order polynomials to determine the best predictive validity. For both upper-extremity tests, a strong linear association between repetitions and relative intensity was found (R2 = 0.97–1.00). By contrast, for the lower-extremity tests, the associations were fitted better with a 2nd order polynomial (R2 = 1.00). The results from the present study provide formulas for predicting maximal muscles strength based on submaximal resistance in four different muscles groups and show a muscle-group-specific association between repetitions and intensity.

“…[ 6 ] The assessment of the force can be supported by use of isokinetic machines with an objective data on the functional recovery. [ 7 ] Costantino et al[ 8 ] evaluated patients with proximal humeral fractures treated with a locking plate, and they used isokinetic test for analyzing the recovery of strength and its correlation with clinical and functional outcomes. They reported that, the isokinetic test can give objective data on strength recovery and could help the surgeon’s clinical evaluation to assess the functional recovery of the operated shoulder over time.…”

BACKGROUND: The aim of this study was to compare the clinical and isokinetic evaluation of distal radius fractures treated by volar locking plate (VLP) and external fixator. METHODS: The study included fifty patients with distal radius fracture type C1/C2/C3. Twenty-seven patients (12 men, 15 women; mean age 49.5±4.42) underwent open reduction and VLP fixation, and 23 patients (10 men, 13 women; 52.1±4.6) underwent closed reduction and external fixation. The follow-up period was at least 12 months and the mean following time was 13.5±1.02 (12–15) months. The functional parameters measured were range of motion (ROM) and grip strength. Radiographic parameters (radial inclination, palmar tilt, and radial height) and isokinetic evaluation were measured at the 6 months and at the final follow-up after surgery. The isokinetic test was done at the speed of 60º/s. The non-fractured arm was tested first and all results were also expressed as a percentage of that on the normal side. Wrist scores according to the disability of the arm, shoulder, and hand (DASH) questionnaire were used. RESULTS: The DASH scores, grip strength, and palmar flexion were better in VLP group at the 6 months (p<0.05). However, there were no differences between two groups at the one year (p=0.79). Isokinetıc evaluation of the VLP showed that peak pronatıon torque and total pronation work were better than external fıxatıon at the 6 month (p<0.05). At the final of follow-up was seen no significant differences between two groups (p=0.11). CONCLUSION: We looked at external fixation and locked volar plates in a prospective study and we found an improved range of movement and isokinetic evaluation outcome at 6 months after locked plating, but there were no differences between two groups at the final of follow-up. Our study showed no evidence for the superiority of one treatment over the other at the final follow-up.
