“…Test-retest reliability for knee isokinetic strength measurement has been noted as strong with ICCs 0.72 in all studies [11,13,17,19,20,29,32,53,62,72,106,107,116,130] except that of Carpenter et al [32], who reported a range of ICCs from 0.60 to 0.95. Despite strong test-retest reliability, strength values may significantly increase in novice individuals after familiarization with isokinetic measurement suggesting a learning effect [95]. Minimal detectable change (MDC) values have been reported for concentric knee extensor strength PT (33.9 Nm) [62] and body weight adjusted PT for concentric knee extensor (0.03 to 0.05 Nm/kg) and eccentric knee extensor strength = 0.14 to 0.19 Nm/kg [17].…”

BACKGROUND: Knee osteoarthritis (OA) is common among older adults and associated with impaired knee strength. OBJECTIVE: Describe isokinetic testing procedures and clinimetric findings associated with the testing of knee strength in the presence of knee OA. METHODS: Relevant articles were identified by an electronic search of PubMed using the search string "isokinet * AND knee osteoarthritis." RESULTS: One-hundred and twenty-nine relevant articles were found. The articles support the validity and reliability of isokinetic strength testing for patients with knee OA. The responsiveness to various therapeutic interventions has been reported. CONCLUSIONS: Isokinetic dynamometry is a valid and reliable measure of muscle strength in knee OA.

“…Besides, the ICC analysis demonstrated that relative reliability was better between trials 2 and 3 in all isokinetic variables. The requirement of familiarization sessions to achieve a desirable group and relative reliability in strength tests was previously reported in health and disease [14,28,29]. Such requirement could be related to motor learning effect of groups that have never had been submitted to isokinetic dynamometry testing.…”

“…Schaubert and Bohannon [30] reported no familiarization sessions required by older subjects, while Fagher et al [16] reported that at least one familiarization session is required by children. Also, Rodrigues-da-Silva et al [29] showed that osteoarthritis patients require one familiarization session to avoid learning effect.…”

Purpose To determine the amount of familiarization sessions required by breast cancer survivors to achieve a reliable measurement of muscle function assessed using isokinetic dynamometry. Methods Twenty-six breast cancer survivors performed three isokinetic knee extension tests separated by, at least, 48 h. The isokinetic testing protocol included one warm-up set of 10 submaximal knee extensions at 120°/s, followed by two sets of four maximal knee extensions at 60°/s, with 2-min rest interval between sets. Peak torque (PT), time to peak torque (TPT), angle of peak torque (APT), and average power (AP) of each trial was used for the assessment of testing reliability. Percentage change in the mean, typical error, coefficient of variation and intraclass correlation coefficients (ICC 2.1 ) were calculated to determine test-retest reliability. Results For PT, change in mean was lower between trials 2 and 3 than between trials 1 and 2 (4.18% and 13.18%, respectively), and ICC was greater between trials 2 and 3 than between trials 1 and 2 (0.962 and 0.818, respectively). For TPT and APT, ICC was clinically acceptable only between trials 2 and 3 (0.757 and 0.803, respectively). For AP, change in mean was clinically acceptable between trials 2 and 3 (9.84%), while ICC met acceptable reliability between both, trials 1 and 2 and, trials 2 and 3 (0.756 and 0.891, respectively). Conclusion At least one familiarization session is adequate to achieve reliable measurements of muscle function using isokinetic dynamometry, while avoiding the impact of learning effect of the measurements in breast cancer survivors.

Objectives: To evaluate the effects of interferential current and photobiomodulation in patients with knee osteoarthritis. Design: A randomized, placebo-controlled, double-blind clinical trial. Setting: Physiotherapy Clinic of City University of São Paulo. Subjects: A total of 184 patients with knee osteoarthritis were recruited and, of these, 168 were included and randomized into four groups with 42 each: interferential current, photobiomodulation, interferential current plus photobiomodulation or placebo groups. One hundred and sixty-four patients completed the study. Intervention: Patients received 12 sessions (three times a week) of treatment: 30 minutes of interferential current (active or placebo) followed by photobiomodulation (active or placebo). Main measures: Primary outcome: pain intensity at rest and during movement (numeric rating scale) after 12 sessions. Secondary outcomes: functional capacity (Timed Up & Go and Sit and Lift tests and Lequesne and WOMAC questionnaires), pressure pain threshold, conditioned pain modulation, and muscle strength production (isokinetic evaluation). Patients were assessed at baseline, after 12 sessions, and three and six months after the end of the treatment. Results: Interferential current plus photobiomodulation reduced pain intensity at rest and during movement compared to placebo and interferential current at all time points ( P < 0.05). Photobiomodulation reduced pain intensity at rest compared to placebo at all time points ( P < 0.05) and compared to interferential current at six months follow-up ( P < 0.05). Photobiomodulation reduced pain intensity during movement compared to placebo at six months follow-up ( P < 0.05). Conclusion: Interferential current plus photobiomodulation or isolated photobiomodulation improve pain intensity in knee osteoarthritis.
