Multidimensional evaluation is necessary to assess hand function in patients with Charcot-Marie-Tooth disease type 1A.

Background: Charcot-Marie-Tooth (CMT) disease type 1A (CMT1A) is the most common hereditary neuropathy. Several studies have assessed the relation between axonal loss and grip strength; however, the functional impact on dexterity and health-related quality of life (HRQoL) is unknown. We hypothesized that the severity of axonal loss will be correlated with loss of function and HRQoL.

Comparison of psychometric properties between the Labin, a new electronic dynamometer, and the Jamar: Preliminary results in healthy subjects.

Many instruments exist for measuring grip strength. The Jamar hydraulic hand dynamometer is currently the gold standard. The Labin is a prototype electronic dynamometer that can also measure maximum grip strength.
