“…The measuring arms on each handle are identical in design and made of aluminum. Unlike the bending strain measurement approach used in [17], the grip force on each arm is measured using a pair of shear strain gauges installed in pockets near the foot of the arm using the method proposed by Pronk [19]. Each measuring arm is assembled to a common aluminum base and affixed with two machine screws.…”

“…(2) the friction force is present in the gripping action but does not substantially contribute to the normal force; (3) the measurement device can be improved using a shear strain method originally proposed by Pronk [19]; and (4) the grip strength measured with a Jamar handle is not well-correlated with that measured with a cylindrical handle. This study tested these hypotheses by developing a new dynamometer and evaluating it both theoretically and experimentally.…”

“…19 Tip pinch and key pinch were measured with the Lode pinch-grip dynamometer, which is similar to the Preston pinch dynamometer. 20 Tip pinch was measured with the index finger on the top and the thumb below and with the other fingers flexed. Key pinch was measured with the thumb on the top and the radial side of the index finger below.…”

Abstract-Background: Several problems are associated with manual muscle testing and dynamometry in the hands of patients with Charcot-Marie-Tooth (CMT) disease. Objective: To evaluate the efficacy of the Rotterdam Intrinsic Hand Myometer (RIHM) to directly measure intrinsic hand muscle strength in CMT disease. Methods: We measured hand muscle strength and hand function in 41 patients with CMT disease. Results: RIHM measurement of intrinsic strength had excellent reliability. We found overlapping RIHM strength values in Medical Research Council grades 3 to 5. High grip and pinch strength could be found in patients with severe intrinsic muscle weakness. RIHM measurements were more strongly correlated with fine motor skills of the hand than grip and pinch strength. Conclusions: The Rotterdam Intrinsic Hand Myometer is a reliable instrument to measure intrinsic hand muscles strength in patients with CharcotMarie-Tooth disease, providing more detailed information than manual muscle testing and a more direct assessment of intrinsic muscle loss than grip and pinch dynamometers.

“…The strain-gauge transducer for one direction measures the shear force that results from a load on the platform, and is only sensitive for that one direction. The influence of forces and torques in other directions is low (GUMMERS, 1976;PRONK and NIESING, 1981). This property makes it possible to connect three transducers with stiff beams and still have little (interference) problem.…”
