Hand forces to be considered in a joint-protection strategy for women with hand osteoarthritis

Osteoarthritis of the hands occurs as a part of nodal osteoarthritis (a form of osteoarthritis that runs in families). It is more common inn women aged 40 or 50 years, around the menopause. McGee and Mathiowetz performed the study to depict whether a joint-protection strategy changes the mechanics of opening a sealed jar.

The study included 31 adult women with hand osteoarthritis who tried to open a “sealed” jar instrument when using and not using the non-skid material. For each trial, grip force, torque, success, and pain were noted.

This resulted in participants using less grip force when twisting with their left hand. The prominent torque and success, besides the least amount of grip force across time, and the pain was recorded when the left hand turned the lid, the jar was held vertically, the right hand supported the base, and nonskid material was utilized.

It was culminated from the study that women with hand osteoarthritis should be educated to consider the hand they use and their technique when opening sealed jars. The load on arthritic joints, pain, and dysfunction might increase with the utilization of nonskid material without additional reasoning. Further research on task kinematics and the kinetics of the stabilizing hand is required.
