To investigate the correlation of the grip strengthwith sonographic measurement of interosseous muscle (IOM) and intermetacarpalspace (IMS) of the hands in carpal tunnel syndrome (CTS) patients. Methods.A total of 96 hands of 48 female patients constituted the study group. Ofthose, 36 hands of 18 patients (mean age: 50.2 ± 9 years) had CTS confirmed byelectro-diagnostic tests. Sixty hands of 30 healthy volunteers (mean age: 45.2± 9.7 years) constituted the control group. Grip strength was assessed by Jamarhand dynamometer. IOM and IMS dimensions for all hands were measuredsonographically at three levels (2nd, 3rd and 4thintermetacarpal; palmar side for IMS, dorsal side for IOM) by the sameradiologist. Spearman and Mann Whitney U tests were used for statisticalanalysis. Results. The median hand grip strength wasdetermined as 11.3 kg (min-max = 7.2-18.1 kg) in the CTS group and 19.5 kg(min-max = 7.8-30.5 kg) in the control group, with a statistical differencebetween the two groups (p < 0.03).In both groups, there was a positive correlation between the IOM-IMS dimensionsand grip strength (p < 0.05).Sonographically, IOM-IMS measurements in CTS group were significantly lowerthan control group (p < 0.01). Conclusion. To our knowledge, this is the first study evaluating thecorrelation of grip strength and the sonographic IOM-IMS measurements in CTSpatients. The muscular atrophy, whichis generally a finding of advanced disease, may be revealed by sonographicalmeasurements earlier than the physical examination findings.
