Cite this article: Soto R B. Dynamometer Measurements of Grip Strength in Frail Elderly Inpatients. J J Intern Medicine. 2016, 2(1): 018. Sarcopenia and frailty are two clinical entities that generate loss of independence. Sarcopenia is characterized by loss of skeletal muscle mass and strength and is a risk factor for fraility and physical disabilities [1]. To diagnose fragility must is necess...

BACKGROUND Even though handgrip strength (HGS) is considered a simple and reliable method to evaluate muscle function and, indirectly, the nutritional status in clinical settings, there is still no consensus concerning its use in patients with chronic kidney disease (CKD) undergoing dialysis. This study presents a systematic review of the literature on the use of HGS as a parameter for nutritio...

A Forced Roll Mechanism was designed and built at the Hydromechanics Laboratory at the United States Naval Academy. The FRM was designed as a dynamometer that forces a planing hull model in roll and measures the resulting roll moment as well as the heave and sway forces. The model is fully restrained in all six degrees of freedom. The dynamometer can be configured to either oscillate the model ...

[Purpose] The aim of this study was to develop a method of measuring isometric shoulder joint muscle strength using a handheld dynamometer with a belt and investigate its test-retest reliability. [Subjects] The subjects comprised 40 healthy adults. [Methods] Six types of isometric shoulder muscle strength were measured twice, and reliability was assessed. [Results] The intraclass correlation co...

A recent improvement on the ancillary instrumentation and on the acquisition software of the 100 kN and 500 kN INRIM six-component dynamometers makes it possible to measure the parasitic components at static conditions and during the weight transition too, in order to weigh up the influence of the dynamic phenomena on the value of axial load. This paper presents the main results of the evaluati...

CONTEXT Scapular strength deficits have been linked to shoulder dysfunction. OBJECTIVE To establish normative data on the scapulothoracic musculature in normal subjects using a handheld dynamometer. DESIGN Descriptive normative data study. SETTING Field research. SUBJECTS 172 subjects with varying levels of overhead activity. METHODS A handheld dynamometer was used to test the upper, ...

Vehicles such as buses, delivery trucks, mining equipment, and motorsport vehicles often repeat a highly defined pattern, route, or track during normal use. For these vehicles, standard dynamometer drive cycles are of little use. In this paper it is proposed that deriving a vehicle drive cycle from empirical data collected from on-board vehicle sensors would produce more accurate vehicle charac...

OBJECTIVE To investigate the relation between functional mobility and dynapenia in institutionalized frail elderly. METHODS A descriptive, correlational study involving 26 institutionalized elderly men and women, mean age 82.3±6 years. The instruments employed were the Mini Mental State Examination, the Geriatric Depression Scale, the International Physical Activity Questionnaire, the Timed U...

[Purpose] The purpose of this study was to evaluate hip flexor and extensor strength due to differences in posture measurement. [Subjects and Methods] Healthy adults (26 males and 24 females) were enrolled. Using a hand-held dynamometer, hip flexor and extensor strengths were measured in various postures and in a basic posture (sitting posture and hip/knee joint flexed 90°) according to the Man...
