Is there a correlation between the grip strength and the intrinsic muscles/intermetacarpal spaces of the hand?: An ultrasonographic study

Purpose: Gripping is a unique human ability and an extremely complicated action. The aim of this study is to investigate the correlation of the grip strength with sonographic measurement of intrinsic muscles (IM) and the intermetacarpal spaces (IMS) of the hand. Materials and methods: A total of 38 healthy volunteers (mean age:39.4 years) were examined. All the patients were first evaluated by a physiatrist to rule out any pathology involving the hand. Grip strength was assessed by JAMAR hand dynamometer. Afterwards, IM and IMS areas for both hands (n:76) were measured sonographically at three levels (2nd,3rd an…
