Specializes in Addiction Medicine

Antipsychotic drugs can reduce arm swing due to the side-effect called akinesia or parkinsonian syndrome, not the disease. Injury to the arm or shoulders and diseases like arthritis.

Reduced arm swing may be caused by muscle soreness, problems with the shoulder joint, muscle rigidity (cerebral palsy, Parkinsons, MS, stroke, etc.), casual walking technique, and mistaken observation.
