CDIP-58 can measure the impact of botulinum toxin treatment in cervical dystonia

We compared the responsiveness of the Cervical Dystonia Impact Profile (CDIP-58), Medical Outcome Study Short Form-Health Survey (SF-36), Functional Disability Questionnaire (FDQ), and Pain and Activities of Daily Living subscales of the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) in participants with cervical dystonia treated with botulinum toxin A. Subscales of CDIP-58 were more sensitive in detecting statistical and clinical change than comparable subscales of the SF-36, FDQ, and TWSTRS.
