Prevalence of spasticity and spasticity-related pain among patients with Amyotrophic Lateral Sclerosis.

Abstract

Although they are common symptoms of ALS, there is little information on the prevalence of spasticity and spasticity-related pain. Consecutive patients were prospectively recruited from an ALS referral center. Clinical assessment, functional scores, features of spasticity-related pains has been recorded. In a cohort of 150 patients, 36% presented with spasticity. Spastic patients were younger, with a longer duration of disease. Spasticity accelerates the functional decline of patients. Spasticity-related pain was reported in 42.5% of spastic patients with mild pain. However, 16.7% of spastic patients presented significant pain with numeric rating scale≥4. More clinical trials are needed to treat spasticity more effectively and to relieve ALS patients.
