This study aims to investigate the effect of closed kinetic chain exercises on proprioception and inversion/eversion strength imbalance of the ankle joint in track and field athletes with medial tibial stress syndrome. (ac.ir)
The evaluation of absolute error of ankle joint position sense was done using the isokinetic dynamometer device actively on the leg with medial tibial stress syndrome. (ac.ir)
A significant difference was observed between closed kinetic chain exercises and healthy groups with the control group at post-intervention proprioception and inversion/eversion strength imbalance of the ankle joint. (ac.ir)
It seems that under the influence of a specialized training course of the closed kinetic chain exercises for athletes, because of the significant changes in establishing the muscle balance of the evertor and invertor muscles of the ankle joint and the sense of proprioception in this area, the sports performance of the athletes improves. (ac.ir)
It could be speculated that emphasis should be placed on increasing the strength of the ankle joint for a "ground up" approach. (preventinjuries.org)
Strengthening of the large and small muscles crossing the ankle joint is assumed to change the force distribution for these muscles and to increase the use of smaller muscles. (preventinjuries.org)
To induce long-lasting stretching on the plantar flexors and to improve standardization of the stretch training by quantifying the angle in the ankle joint while stretching, a calf muscle stretching orthosis was developed. (researchgate.net)

CONCLUSION: Findings of this systematic review with meta-analysis suggested that rehabilitative approaches might be effective in reducing pain in muscle-related TMD patients. (iospress.com)

1) Characteristics of an isokinetic exertion are constant velocity throughout a predetermined range of motion. (cdc.gov)

Considering hand-held dynamometry's ease of use, portability, cost, and compact size, compared with isokinetic devices this instrument can be regarded as a reliable and valid instrument for muscle strength assessment in a clinical setting. (nih.gov)
More than 3 decades ago, the clinical observation that patients with rickets and osteomalacia displayed proximal myopathy suggested a direct link between hypovitaminosis D and muscle function [ 7 ]. (hindawi.com)
The amount of force that is considered a significant difference in strength using dynamometers can vary depending on the muscle group being tested, the individual's age and gender, and the clinical setting. (edgemobilitysystem.com)

As detailed below, some investigators have been able to demonstrate that the results of certain isokinetic strength tests (for example, an isokinetic exertion from floor to chest height) appear to be correlated with the amount of weight individuals were willing to lift for infrequently performed tasks. (cdc.gov)

This study will evaluate the association of work ability with modifiable parameters such as muscle strength and functional ability. (researchprotocols.org)

abstract = "Although a risk of occupational musculoskeletal diseases has been identified with age-related strength degradation, strength measures from working group are somewhat sparse. (elsevierpure.com)

This means that the results of dynamometer testing are not influenced by the clinician's subjective judgment. (edgemobilitysystem.com)
The present study aimed to evaluate the performance of knee muscles using an isokinetic dynamometer to determine muscle dysfunction in patients with newly diagnosed hypothyroidism, and to compare the results with that in a healthy control group. (ftrdergisi.com)

Novice runners will be randomly assigned to one of three groups: an isolated ankle strengthening group (strength, n = 40), a functional balance training group (balance, n = 40) or an activity-matched control group (control, n = 40). (preventinjuries.org)

They used ultrasonography to image the quadricep muscle during knee extension movements in an isokinetic dynamometer, a machine that can measure muscle strength. (sciencedaily.com)

However, limited data exist regarding the reliability of RF CSA and how it relates to maximal and explosive strength of the hip flexors in young adults. (wku.edu)
These findings demonstrated that CSA, PT, and RTD may be reliable measures for assessing RF muscle size and maximal and explosive strength capacities of the hip flexors in young, healthy adults. (wku.edu)
As a result, practitioners may consider implementing training programs aimed at increasing the size of the RF in younger adults which may be beneficial for improving the maximal and explosive strength capacities of the hip flexors. (wku.edu)
The device is applied to the muscle group of interest, and the individual is instructed to exert maximal force against the device. (medgearcare.com.au)
Strength Test as a Predictor for Maximal and Acceptable Lifting. (cdc.gov)

Application of NMES has been consistently associated with increased mass, strength, and endurance of both normally and abnormally innervated muscles in a range of pathological conditions. (bmj.com)
The lower muscle strength and endurance determined in overt and subclinical hypothyroid patients as compared to the controls suggest that myopathy occurs in the early stages of hypothyroidism and that it is a condition that should be evaluated at the time of diagnosis. (ftrdergisi.com)

Supraspinatus muscle is one of the major prime movers and stabilizers of shoulder and is highly susceptible to overloading and tendinopathy. (jssm.org)
and between supraspinatus tendon and strength would assist health care practitioners for developing training regime. (jssm.org)
The objectives of this study are to evaluate 1) the association between structural abnormality of supraspinatus tendon and shoulder pain and 2) the association between structural abnormality of supraspinatus tendon and shoulder strength. (jssm.org)
We hypothesized that structural abnormality of supraspinatus tendons positively associated with shoulder pain and negatively associated with shoulder muscle strength among elite swimmers. (jssm.org)
Supraspinatus tendon condition was evaluated using diagnostic ultrasound imaging and shoulder internal and external rotation strength was evaluated by the isokinetic dynamometer. (jssm.org)
