Journal of Hand Surgery (European Volume), 2021 We performed a cadaver study using 18 fresh-frozen adult forearms and hands to compare the tendon loads required to generate progressively greater key pinch (0.5 kg to 2 kg) after three different surgical procedures to treat trapeziometacarpal osteoarthritis: isolated trapeziectomy, trapeziectomy followed by ligament reconstruction with tendon ...

Contribution to the study of stresses in the thumb column during key pinch grip
Hand Surgery and Rehabilitation, 2023The aim of this study was to calculate the stress acting on the trapeziometacarpal joint during an key pinch grip.We used profile X-rays of the thumb to measure the various bony and muscle lever arms. We assessed the angles of action of the muscular elements involved in the thumb column.

The Journal of Hand Surgery, 2006 To show biomechanically that the brachioradialis (BR) muscle can be transferred to restore key pinch and forearm pronation simultaneously.Nine fresh-frozen forearms were thawed and instrumented with a custom muscle-tendon excursion jig. Maximum BR muscle-tendon excursion was measured with the wrist and thumb mobile.

Key concepts of pinch analysis
Pinch Analysis for Energy and Carbon Footprint Reduction, 2020A designer can blend key concepts with the intuition and experience of the individual process technology, giving better designs. The pinch design method starts the design where the problem is most constrained.

Intertrial Rest for Maximum Grip and Key Pinch Strength in Japanese Young Adults
The American Journal of Occupational Therapy, 2019Abstract OBJECTIVE. This study investigated the most appropriate intertrial rest period for maximum grip and key pinch strength measurements involving three trials. METHOD. The study included 40 male and 40 female participants. Using a repeated-measures design, six intertrial rest periods—15 s, 30 s, 60 s, 90 s, 120 s, and

Key Pinch in Healthy Adults: Normative Values
Journal of Hand Surgery (European Volume), 2008Intra-individual and inter-individual variations of key pinch strength were analysed in a standardised manner for healthy Caucasian adults (female n = 403; male n = 366) aged between 20 and 95 years. The mean strength was less in women (right 6.6 kg; left 6.1 kg) than in men (right 10.4 kg; left 9.7 kg).

Effect of elbow position on grip and key pinch strength
The Journal of Hand Surgery, 1985Twenty-nine college women participated in a study to investigate the effect of elbow position on grip and key pinch strength evaluations. Standardized instructions and positioning were followed with the exception of the two elbow positions. The elbow was flexed to 90 degrees in one test condition and it was fully extended in the other.

Precise pre- and postoperative assessments are fundamental to recording the quality of recovery after ulnar nerve repair. Because of its imprecision, manual muscle testing is being replaced by dynamometry to measure grasping and key-pinch strengths. However, both grasping and key pinch are dependent not only on the ulnar nerve but also the median and ...

The key pinch force in a group of 262 healthy children between 5 and 12 years was measured. A clear correlation was observed between age and key pinch strength. The differences between the left and right hand grips and between girls and boys were not significant.
