Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Motor Retraining and Stretching Exercises
A structured physical therapy program focusing on stretching tight muscles, strengthening antagonist muscles, and relearning normal movement patterns to reduce dystonic symptoms and improve functional mobility.
Muscle Relaxants and Anticholinergic Agents
Pharmacological management using centrally-acting muscle relaxants or anticholinergic medications to reduce involuntary muscle contractions and improve movement control.
Additional treatment options
Botulinum Toxin Injections
Targeted injection of botulinum toxin into overactive muscles to temporarily weaken specific muscle groups, reducing dystonic postures and pain associated with abnormal muscle contractions.
procedureDeep Brain Stimulation
Surgical implantation of electrodes in specific brain regions (typically globus pallidus internus) with a neurostimulator to modulate abnormal neural activity causing dystonia.
surgicalCognitive Behavioral Therapy and Coping Strategies
Psychological support including CBT and stress management techniques to help patients cope with the chronic nature of dystonia, address secondary anxiety or depression, and improve quality of life.
