Motor deficits, including unilateral or bilateral weakness, plegia, ataxia, spasticity, and loss of complex movement execution, can occur during any brain tumor illness. Tumor location, treatment effects, and medications contribute to these deficits. Motor dysfunction has been associated with significant deterioration in health-related quality of life in patients with primary and metastatic brain tumors. Significant decrease in median overall survival has been reported in patients with motor deficits, although the reasons for this are unclear. Motor deficits, particularly gait impairment, contribute to significant symptom burden at end of life, and are the most common reasons for initiation of hospice care. Interventions must focus on prevention and amelioration of motor dysfunction throughout the disease course in order to preserve quality of life. The impact of exercise in prolonging survival and improving quality of life requires further study.
