The purpose of this study was to estimate, using the Position-Specific Global Index (PSGI) of Lower-Limb Muscle Strength, the extent to which muscle strength is independently associated with functional walking capacity. We performed an observational, cross-sectional study with 63 patients poststroke (onset between 3 and 12 months) at a major teaching hospital in an urban Canadian city. We asses...

This retrospective study was undertaken to determine the test-retest reliability of hand-held dynamometer strength testing for 18 extremity muscle groups. To assess reliability, I compared three dynamometer strength scores recorded for each muscle group on the strength score forms of 30 neurologically involved patients, using the Pearson product-moment correlation and a one-way analysis of vari...

The purpose of this investigation was to examine the association between cognitive ability and upper body muscle strength. Two sources of existing data were pooled for this examination. Thirty-eight older participants diagnosed with Alzheimer's disease or dementia (25 women, 13 men; age = 83.2 +/- 5.6 years, MMSE score = 16.75 +/- 7.04, M +/- SD) underwent an assessment of grip strength via han...

BACKGROUND Several problems are associated with manual muscle testing and dynamometry in the hands of patients with Charcot-Marie-Tooth (CMT) disease. OBJECTIVE To evaluate the efficacy of the Rotterdam Intrinsic Hand Myometer (RIHM) to directly measure intrinsic hand muscle strength in CMT disease. METHODS We measured hand muscle strength and hand function in 41 patients with CMT disease. ...

PURPOSE To establish hand-held dynamometry (HHD) maximal isometric muscle torque (MIT) reference values for children and adolescents who are developing typically. METHODS The MIT of 10 upper and lower limb muscle groups was assessed in 351 Caucasian youth (4 years 2 months to 17 years) using a standardized HHD protocol, previously shown to be feasible, valid, and reliable. RESULTS The mean ...

INTRODUCTION The extent to which gastrocnemius muscle and Achilles tendon properties contribute to the impaired walking endurance of claudicants is not known. METHODS Ultrasound images quantified muscle architecture of the lateral and medial gastrocnemius (GL and GM) and were combined with dynamometry during plantarflexor contractions to calculate tendon stress, strain, stiffness, the Young m...

We present here an unusual case of a sequential avulsion fracture of the anterior inferior iliac spine (AIIS), occurring first in the right and then the left AIIS, during long jump attempts. The case of a 17 year old boy with pain around his right groin, which first occurred during a long jump attempt, is presented. Radiographic examination revealed an avulsion fracture of the right AIIS. After...

CONTEXT Hand-held dynamometry (HHD) has been shown to be a reliable, objective way to obtain strength measurements in elderly and physically impaired subjects. OBJECTIVE To estimate the intratester, intertester, and intersession reliability of HHD testing of lower extremity movements in young, healthy subjects. DESIGN Repeated measures. SETTING Sports medicine laboratory. PARTICIPANTS N...
