The effect of vertical dimension of occlusion (VDO) on maximizing isometric deltoid strength (IDS) was measured in subjects with deep overbite. Sixteen female dental students with deep dental overbite and no history of temporomandibular joint disorder (TMD) were used as their own control and tested for isometric strength of the deltoid muscles, using a hand held strain gauge. Measurements were ...

background :many studies have reported the increase in strength of the untrained contralateral limb after unilateral training. the aim of this study was to compare the cross education effect in the young and elderly persons.   methods : in this quasi-experimental and pre-post study, 12 young people aged 28.25 ±3.11 years and 12 elderly persons (aged 73.08 ± 5.3 years) participated. the subjects...

Large joint damage often leads to inability work and disability that requires long-term treatment. The development of osteoarthritis is accompanied by changes in the muscles special rehabilitation measures are needed restore their strength, symmetry load during standing steps walking. Objective. To determine most vulnerable lower extremities conditions hip knee joints using a mathematical model...

Iliotibial band syndrome (ITBS) is a common overuse running injury. Atypical secondary plane lower-extremity and trunk biomechanics during running are likely to play a role in the etiology of ITBS [1, 2]. Proximal factors such as a large hip adduction angle may increase the tensile strain in the iliotibial band during the stance phase of running [1]. A lack of ability to limit hip adduction may...

OBJECTIVES This was a descriptive study involving maximal and average isometric strength measurements of the cervical musculature. The purpose of this study was 1) to determine the test-retest reliability of a computerized dynamometer for measuring muscular strength of the neck flexor and extensor muscles in a healthy population, and 2) to afford a normative database of the maximal and averaged...

Ahn, N, Kim, H, Krzyszkowski, J, Roche, S, and Kipp, K. Influence of the bar position on joint-level biomechanics during isometric pulling exercises. J Strength Cond Res 35(6): 1484–1490, 2021—The purpose this study was to investigate influence ankle, knee, hip net joint moments (NJMs), relative muscular effort (RME), vertical ground reaction forces (GRFs) exercises, such as midthigh pull. Eigh...

Context. Maximal voluntary isometric contraction, a method quantitatively assessing muscle strength, has proven to be reliable, accurate and sensitive in amyotrophic lateral sclerosis. Hand-held dynamometry is less expensive and more quickly applicable than maximal voluntary isometric contraction. Objective. To investigate if hand-held dynamometry is as reliable and valid as maximal voluntary i...

BACKGROUND AND PURPOSE Although stroke survivors often display abnormal joint torque patterns, studies of torque-coupling in the lower limb are lacking, despite their potential impact on gait abnormalities. METHODS Twenty-two chronic ambulating stroke subjects and 11 age-matched control subjects produced isometric hip torques in the frontal and sagittal planes with the hemiparetic leg (or ran...
