Occupational Therapy in Patients With Multiple Sclerosis

Overview

Limb apraxia is defined as the inability to correctly perform skilled and/or learned limb movements, which cannot be explained by elementary motor and sensory deficits or cognitive problems. Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system and the leading cause of disability in young adults. Apraxia and impaired manual dexterity are common problems in patients with MS leading to impaired activities of daily living. However, a specific training program to improve apraxia as well as manual dexterity in MS is lacking. In this study, the investigators want to evaluate the impact of a targeted occupational therapy program on apraxia and manual dexterity in patients with MS that have dexterity problems. Patients routinely seen in the investigators MS consulting hour, fulfilling all inclusion and exclusion criteria and willing to participate in the study will be evaluated for Apraxia and manual dexterity. In case of Apraxia and/or impaired manual dexterity, patients will be randomized 1:1 using sealed envelopes to receive occupational home therapy (experimental group) or general physical exercises (control group) for 4 weeks. At study entry and study end after 4 weeks, apraxia and manual dexterity will be tested in all patients.

Background Limb apraxia is defined as the inability to correctly perform skilled and/or learned limb movements, which cannot be explained by elementary motor and sensory deficits or cognitive problems. It impairs real object/tool use as well as pantomime and imitation of gestures affecting both sides of the body and can be a major source of disability independent of other neurological deficits. It significantly affects activities of daily living (ADL) and is associated with poorer outcome for independent living or return to work. Apraxia is largely based on left parieto-frontal damage due to focal injury or more widespread neurodegeneration of cortical areas and/or their connections. However, apraxia has been described in damage of the right hemisphere, although less frequent and severe. Apraxia is increasingly recognized as a clinical problem in restorative neurology and various approaches were described how to treat the disorder. Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system and the leading cause of disability in young adults. It is characterized by focal demyelination as well as axonal damage. MS has been classically thought of as a typical white matter disorder. However, early pathology studies and recent magnetic resonance tomography (MRI) studies show demyelination in the cortex and deep gray matter nuclei. Grey matter damage starts early in the disease and substantially affects cognitive functioning. Apraxia and impaired manual dexterity are common problems in MS leading to impaired activities of daily living. However, a specific training program to improve apraxia and manual dexterity in MS is lacking. In this study, we want to evaluate the impact of a targeted occupational therapy program on apraxia and manual dexterity in patients with MS that have dexterity problems. It is a rater-blind, randomized, controlled trial. Patients routinely seen in our MS consulting hour, fulfilling all inclusion and exclusion criteria and willing to participate in the study will be evaluated for Apraxia using the AST (Apraxia Screen of TULIA). In case of Apraxia patients will be randomized 1:1 using sealed envelopes to receive occupational home therapy (experimental group) or general physical exercises (control group) for 4 weeks (4 times 5 days in a row). At study entry and study end after 4 weeks, apraxia will be tested in all patients using the extended version of the AST, the TULIA. Furthermore, a questionnaire on "activities of daily living" and "quality of life" will be evaluated, and test regarding cognition, spasticity, ataxia, fatigue as well as the EDSS will be performed. Objective To evaluate the impact of a targeted occupational therapy program on apraxia and manual dexterity in patients with MS. Methods see above.
