Gait Disturbance in Patients with Schizophrenia in Relation to Walking Speed, Ankle Joint Range of Motion, Body Composition, and Extrapyramidal Symptoms
2025
Overview
Background/Objectives: In patients with schizophrenia, gait disturbances (e.g., reduced walking speed and stride length) are linked to neural dysfunction and extrapyramidal symptoms. To inform gait rehabilitation strategies, this study examines the relationships of walking speed with extrapyramidal symptoms, stride length, antipsychotic dosage, ankle joint range of motion, and body composition in patients with chronic schizophrenia. Methods: Sixty-eight patients with chronic schizophrenia were included. All variables were described based on their measurement levels using non-parametric methods. Spearman’s rho was calculated to assess correlations. For multiple linear regression analyses, backward stepwise elimination was used to determine variables associated with walking speed. Statistical significance was set to p < 0.05. Results: Walking speed was positively correlated with stride length, chlorpromazine-equivalent dose, ankle plantar flexion, body mass index, bone mineral content, trunk muscle mass, and skeletal muscle mass index. In contrast, it was negatively correlated with drug-induced extrapyramidal symptoms scale (DIEPSS) scores for gait, bradykinesia, tremor, overall severity, and age. The multiple linear regression indicated that DIEPSS 2 bradykinesia level and ankle plantar flexion angle, adjusted for a 26% variance, best explained the walking speed. Conclusions: A lower bradykinesia severity and a higher ankle plantar flexion are associated with higher walking speeds. Thus, it is critical to assess stride length, bradykinesia, angle/limitation/torque of ankle plantar flexion, trunk and upper and lower limb muscle masses, and walking speed in patients with chronic schizophrenia. Specific strategies for gait rehabilitation should focus on stride training, plantar flexion strengthening exercises, and balance training.
