“…Previous studies with older adults showed that LOAs were moderate to high ranging from 21 and 54% for peak torque, average peak torque, work, and power of knee flexors and extensors in older adults 3,17,18 . These findings indicate that the measurements tended to disagree between the two evaluations and a low precision of the test is presented.…”

“…Muscle strength has been evaluated with different methods, such as manual tests 3 , hand-held dynamometer 4,5 , and isokinetic dynamometer 6,7 . The isokinetic dynamometer has been considered the gold-standard evaluation 7,8 because it allows a quantitative evaluation of muscle function, throughout variables such as torque, power, and endurance 6 .…”

| Background: The isokinetic dynamometer has been considered the gold-standard measurement of muscle performance. However, the reliability for the passive mode in children has not been reported to date. Objectives: The purpose was to evaluate the reliability of the isokinetic dynamometer in passive mode in children. Method: Twenty-one healthy children (ten girls, eleven boys), aged 5 to 12 years (age: 8.5±2.2 years), were evaluated using an isokinetic dynamometer. Each participant was tested twice with a one-week interval and performed five consecutive cycles of knee extension and flexion. The test was performed at 60°/s in the concentric passive mode and the children performed maximal contractions. The measured variables were peak torque, average peak torque, total work, and average power, time to peak torque and angle of peak torque for dominant and non-dominant lower limbs. Reliabilities were determined using intraclass correlation coefficient (ICC 3,1 ), standard error of measurement (SEM and SEM%), and coefficient of variation (CV). Results: We found good reliability in both lower limbs for peak torque, average peak torque, total work and average power of knee flexors and extensors, with ICC 3,1 values greater than 0.80; SEM ranging from 6.7 to 79.2; SEM% ranging from 10.4% to 16.8%; CV lower than 15%. Bland-Altman analysis showed that the bias was low than 10% and limits of agreement (LOAs) ranging from 33.9% to 59.2%, and -28.8% and -52.8%, showing that measures tended to disagree. However, time to peak torque (ICC 3,1 <0.68; SEM > 0.34; SEM%>37.4%; CV>41.7%; bias >24.0%; LOA>101.0%) and angle of peak torque (ICC 3,1 <0.76; SEM>9.3; SEM%>27.6%; CV>15.3%; bias>11.0%; LOA>61.0%) were not reliable. Conclusions: The findings indicate that isokinetic evaluation in passive mode for knee extensors and flexors of dominant and non-dominant lower limbs of children without disabilities was reliable for peak torque, average peak torque, work, and power. However, average time to peak torque and angle of peak torque were not reliable.Keywords: isokinetic evaluation; children; knee; reliability; rehabilitation; movement.

“…Failure to recognize extreme joint range of movement can lead to joint instability and traumas to repetitive stress [36][37][38]. Decreased muscle strength can occur in children with limb pain and joint hypermobility [39]. There is evidence that hypermobility syndrome is a multisystemic manifestation, incorporating three main components: chronic pain, autonomic dysfunction, and dysfunction of gastrointestinal motility [6,8,26,30,32,39,40].…”

Background: Joint hypermobility is defined as a wide range of movements beyond the physiological limits, it has been recognized in healthy people, gymnasts, acrobats, and carriers of genetic affections of connective tissue. A survey among young adults was conducted to describe the frequency of joint hypermobility, estimating its impact on function and quality of life. Methods: Volunteer university students aged 18 to 25 years old who answered a valid 5-item questionnaire about hypermobility, a physical activity questionnaire, and the Brazilian version of the Medical Outcome Survey Short Form 36 (SF-36) were included. Hypermobility was also assessed by a guided self-examination, with Beighton's criteria being scored and scores greater than or equal to 4 or less than 4 being discriminated. Results: A total of 388 subjects were included, of which 299 were women (77.06%) and 89 were men (22.94%); the median age was 23 years old. Generalized joint hypermobility (Beighton score ≥ 4) was observed in 104 individuals (26.8%). Localized hypermobility (Beighton score 1-3) was observed in 135 (34.79%) individuals, where the hypermobility of the 5th finger was the most frequent in 165 (57.47%) individuals, followed by hypermobility of the thumb in 126 (32.56%) individuals, hypermobility of the elbows and knees each in 72 (18.6%) individuals, and hypermobility of the spine in 69 (17.79%) individuals. The descriptive observation of physical activity indicated regular practice. The correlation coefficients between the SF-36 domains and hypermobility scores were very low and statistical comparison not significant. Conclusion: In this population of youngsters, predominantly women, localized hypermobility was more frequent than generalized hypermobility; however, with low impact on health domains and quality of life scores, estimated in each domain of the SF-36, the physical and mental component scores, and the time dedicated to physical activity.

“…Functional outcomes are considered subjective methods to evaluate patient progress after rehabilitation protocols (e.g., the Lysholm, Tegner, International Knee Documentation Committee IDKC, and Cincinnati scores) [ 9 , 22 , 28 ]. Among all RTS criteria, muscle strength is the most important considered criterion [ 9 , 29 ], and the most commonly used methods for its evaluation are manual muscle testing [ 30 ], isometric strength tests [ 30 ] and isokinetic strength tests [ 31 ]. Furthermore, the isokinetic technology is considered “the gold standard” method for evaluating muscle strength, allowing the quantification of muscle strength through the determined angular velocity [ 31 , 32 ].…”

Background: This systematic review and meta-analysis compared the isokinetic strength of the muscular knee joint between quadriceps tendon autografts (QTAs) and hamstring tendon autografts (HTAs) or patellar tendon autografts (PTAs) after anterior cruciate ligament (ACL) reconstruction by determining the isokinetic angular velocity and follow-up time points. The functional outcomes and knee stability at the same time points were also compared using isokinetic technology. Methods: Two independent reviewers searched the Medline (via PubMed search engine), Scopus, Web of Science and Cochrane Library databases to include full text comparative studies that assessed isokinetic strength test following ACL reconstruction. The DerSimonian and Laird method was used. Results: In total, ten studies were included; seven compared studies QTAs vs. HTAs, and three compared QTAs vs. PTAs. Five studies were included in the meta-analysis. Isokinetic strength data were reported 3, 6, 12 and 24 months after ACL reconstruction. Conclusions: The QTAs showed better and significant results with knee flexion compared with HTAs, similar results to PTAs at 6 and 12 months. While HTAs showed better and significant results with knee extension at 6 months and similar results at 12 months compared to QTAs. Furthermore, a standardized isokinetic strength test must be followed to achieve a more specific conclusion and better clinical comparison among participants.
