Questionnaires for arm function assessment in patients with multiple sclerosis

Abstract

Arm dysfunction is one of the disabling manifestations of multiple sclerosis (MS), especially in later stages of the disease. Assessment of the functioning of the upper limbs is necessary to objectify the course of MS, determine the effectiveness of therapy, and individualize rehabilitation measures. The tools that assess the upper extremity dysfunction include tests and questionnaires. Questionnaires (patient-reported outcome measures) represent the special importance, since the opinions and preferences of patients themselves help to implement a patient-centered approach to treatment. The article presents a brief description of three multidimensional MS-specific and four unidimensional MS-nonspecific questionnaires that used in assessment of upper limb function in MS patients. The disease-specific unidimensional Arm Function in Multiple Sclerosis Questionnaire (AMSQ), specifically designed to assess the arm use in patients with MS, is discussed in more detail. The use of AMSQ in the Russian population is possible only after the procedure of cultural adaptation and validation of the Russian version.
