Motor and non-motor outcomes after a rehabilitation program for patients with Functional Motor Disorders: A prospective, observational cohort study.

Abstract

Rehabilitation has proven effective in improving motor symptoms (i.e., weakness, tremor, gait and balance disorders) in patients with Functional Motor Disorders (FMDs). Its effects on non-motor symptoms (NMSs) such as fatigue, pain, depression, anxiety and alexithymia, have not been explored yet. To explore the effects of a validated inpatient 5-day rehabilitation program, followed by a home-based self-management plan on functional motor symptoms, NMSs, self-rated perception of change, and quality of life (QoL). 33 FMD patients were enrolled. Measures for motor symptoms and NMSs were primary outcomes. Secondary outcomes included measures of self-perception of change and QoL. Patients were evaluated pre-treatment (T0), post-treatment (T1), and 3-month follow-up (T2). There was an overall significant decrease in functional motor symptoms, general, physical, and reduced-activity fatigue (for all, p < 0.001). Post hoc comparison showed significant improvements at T1, whereas effects remained significant at T2 for motor symptoms and physical fatigue. Gait and balance, alexithymia, and physical functioning (QoL) significantly improved at T2. More than 50% of patients reported marked improvement at T1 and T2. Our study suggests the benefits of rehabilitation and self-management plan on functional motor symptoms and physical fatigue in the medium-term. More actions are needed for the management of pain and other distressing NMSs in FMDs.
