BACKGROUND: Many countries are experiencing an aging workforce with women workers making up a growing proportion. Workplaces often require employees to complete lifting tasks that require the ability of the hand to grasp an implement (coupling). The National Institute for Occupational Safety and Health (NIOSH) has developed an equation for manual lifting tasks hoping to minimize the potential for a workplace back-injury related to a lifting task. The NIOSH lifting equation relies upon stress variables including a coupling factor...

[Purpose] This study investigates the effects of task-oriented activities on hand function, cognitive function, and self-expression of the elderly with dementia, and then identify the influencing factors on self-expression in sub-factors of dependent variables. [Subjects and Methods] Forty elderly persons were divided into two groups: intervention group (n=20) and control group (n=20). The interventions were applied to the subjects 3 times a week, 50 minutes per each time, for a total of five weeks. We measured the jamar hand dynamometer test for grip strength, the jamar hydraulic pinch gauge test for prehension test, nine-hole pegboard test for coordination test, and Loewenstein Occupational Therapy Cognitive Assessment-Geriatric Population for cognitive function, and self-expression rating scale for self-expression test...

Bilateral saccadic eye movements enhance episodic memory retrieval; however, this usually only occurs for consistent-handed, not inconsistent-handed, individuals. It was hypothesized that inconsistent-handers begin closer to the peak of a Yerkes-Dodson-type inverted-U curve and increasing activation pushes them along the curve eventually decreasing performance, while consistent-handers start at a lower baseline and therefore increasing activation increases their performance. The current study tested this hypothesis by using hand clenching (grip strength) to increase activation at 5 different levels for both consistent- and inconsistent-handers...

Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the hand joints and leading to impairment in hand functions. Evaluation of functional impairment is necessary for assessing patient's quality of life, disease activity, and treatment outcome. To date, many scientific studies assessed the disease activity of patients with RA, but little attention has been carried out to assess these patients' hand functions and dexterity. The purposes of this study were to determine the clinical relevance of the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), hand dexterity with the Purdue Pegboard Test (PPT), and handgrip strength and pinch strengths of RA patients and to look into their relation between each other...

BACKGROUND: Preliminary studies have supported the utility of exercise as a treatment for Charcot-Marie-Tooth disease (CMT) patients. Despite being the most common inherited neuropathy, there remains a paucity of guidelines for CMT management. METHODS: A retrospective chart review was performed on 297 CMT patients. Self-reported exercise and strength results from standardized dynamometer testing were obtained from adult patients' first visits. Values were converted and analyzed based on previously reported age- and sex-matched normative values...

Guerra, RS, Amaral, TF, Sousa, AS, Fonseca, I, Pichel, F, and Restivo, MT. Comparison of Jamar and Bodygrip dynamometers for handgrip strength measurement. J Strength Cond Res 31(7): 1931-1940, 2017-Studies that compared the agreement between Jamar and other models of dynamometers for handgrip strength (HGS) measurement have exhibited variability in the provided results. The lack of comparability between dynamometers led to the development of the Bodygrip dynamometer. This study aims to examine the reliability of the Bodygrip for HGS measurement, to compare it with the Jamar, and to explore the HGS differences between instruments considering the ergonomic effect of using the Bodygrip with 2 different handles...

OBJECTIVE: Patients with acromegaly have decreased body fat (BF) and increased extracellular water (ECW) and muscle mass. Although there is a lack of systematic studies on muscle function, it is believed that patients with acromegaly may suffer from proximal muscle weakness despite their increased muscle mass. We studied body composition and muscle function in untreated acromegaly and after biochemical remission. DESIGN: Prospective observational study. METHODS: Patients with acromegaly underwent measurements of muscle strength (dynamometers) and body composition (four-compartment model) at diagnosis (n = 48), 1 year after surgery (n = 29) and after long-term follow-up (median 11 years) (n = 24)...

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy. Limited incision techniques for carpal tunnel release are gaining popularity. The main advantages of these techniques are less scar load, less pillar pain, shorter recovery, and return-to-work time. However, the completeness of release, and risk of neurovascular injury are always a concern. We devised a method of limited incision release with two mini-incisions and use of nasal speculum and a probe...

BACKGROUND: Cushing's syndrome (CS) is characterized by an excessive secretion of glucocorticoids that results in a characteristic clinical phenotype. One feature of clinical hypercortisolism is breakdown of protein metabolism translating into clinical consequences including glucocorticoid-induced myopathy. While surgery is effective in control of cortisol excess, the effect of biochemical remission on muscular function is yet unclear. METHODS: In a cross-sectional study we analyzed 47 patients with CS during the florid phase (ActiveCS)...

In the assessment of hand and upper limb function, detecting sincerity of effort (SOE) for grip strength is of major importance to identifying feigned loss of strength. Measuring maximal grip strength with a dynamometer is very common, often combined with calculating the coefficient of variation (CV), a measure of the variation over the three grip strength trials. Little data is available about the relevance of these measurements in patients with median nerve impairment due to the heterogeneity of patient groups...
