Designed and validated to fully satisfy regulatory and published FDA guidance for use in drug-labeling claims and measuring changes in how a patient feels and functions. The CMT-HI is a fully valid, reliable, responsive, and disease-specific instrument capable of measuring changes in patient-reported health in patients with charcot marie tooth. The instrument was developed using extensive patient input, including an analysis of 656 patient quotes and a large cross-sectional study involving 407 patients. The CMT-HI is highly relevant to patients, has low patient burden, correlates with markers of disease severity, and demonstrates low floor and no ceiling effects.

Symptom questions within each subscale are weighted based on participant-reported prevalence and average impact as identified through the cross-sectional study. Subscale scores are also weighted to generate a total CMT-HI score (0-100) representing overall disease burden. Inquire about Licensing View All Instruments
