Hand-grip strength

A relatively new approach to nutrition assessment is to evaluate muscle function as an end-organ response. Hand-grip strength (forearm muscle dynamometry), respiratory muscle strength, and muscle re-... 

Depending on the joint affected, measurement of grip strength and 50-feet walking time can help assess hand and hip/knee OA, respectively. 

Musculoskeletal Assess extremities for deformities, swelling, lacerations, or other injuries. Palpate distal pulses for equality, rate, and rhythm compare with central pulses. Ask child to wiggle toes and fingers evaluate strength through hand grips and foot flexion/extension. 

Motor function Assess handshake for ability to lift arm against gravity and motor control move toward target (your hand) assess tremor (resting, action, and postural) of hand assess grip strength. Ask patient to lift leg off bed. Observe for dyskinesias. Stroke (arm and leg weakness), Parkinson s disease (tremor, bradykinesia, rigidity, dyskinesias), essential tremor... 

Deformity of tlie liand may be seen with clironic inflammation. These changes may alter the mechanics of hand fnnction, redncing grip strength and making it difflcnlt to perform nsnal daily activities. 

FIGURE 76.3 Three types of instrumented strength testing devices are shown (a) a representative example of a typical hand held dynamometer (b) an example of an isokinetic strength testing device and (c) a hand dynamometer used to measure grip strength. 

Nicolay, C. W. and A. L. Walker (2005). Grip strength and endurance Influences of anthropometric variation, hand dominance, and gender International Journal of Industrial Ergonomics 35(7) 605-18. 

Various design considerations such as adequate base recesses for hand gripping, curvature of the base insert for adequate strength to support the inner container, etc. were improved upon before a production tool was commissioned. 

Maximum grip strength is achieved with a hand tool grip span between 7.5 - 8 cm (2.9" to 3.1"). The maximum grip force is 45 N (10 lbs.). 

The tenosynovial changes and the associated functional impairment seen when tamoxifen or an aromatase inhibitor adversely affects the small joints of the hand and wrist have been studied in 17 patients [44 j. At 6 months, patients taking an aromatase inhibitor had reduced grip strength and significant tenosynovial... 

Chen, Shih, Chi, 2010b) 24 Male and female/mean 25,24 years 34°C water and 11°C water Gross and fine hand dexterity, grip strength, and muscular activity were found to be positively correlated to skin temperature.
