Test of grip strength using the Jamar dynamometer

Comparison of Rolyan and Jamar dynamometers for measuring grip strength.

This study compared the Jamar and Rolyan hydraulic dynamometers to determine their concurrent validity with known weights as well as their inter-instrument reliability and concurrent validity for measuring grip strength in a clinical setting. Thirty females and 30 males were tested on these two grip strength measurement devices using a repeated measure design. Results showed that the Jamar and ...

Dynamometer Measurements of Grip Strength in Frail Elderly Inpatients

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...

Adult grip strength norms for the Baseline digital dynamometer

Development of an integrated digital hand grip dynamometer and norm of hand grip strength.

This study designs and fabricates a novel integrated digital hand grip dynamometer and analyzes collected grip strength data. The dynamometer directly stores collected data in a computer, unlike those on the market that cannot directly store information. A strain gauge load cell is used as a force sensor. The dynamometer is designed to maximize ergonomics. Excitation voltage of the load cell is...

Pain free grip strength test.

Description The pain-free grip (PFG) test is used to measure the amount of force that the patient generates to the onset of pain; when there is no pain the test result could be regarded as maximum grip strength. It is commonly performed in patients with lateral epicondylalgia (LE). LE is characterised by the presence of pain over the lateral humeral epicondyle which is provoked by at least two ...
