Dry needling at myofascial trigger points mitigates chronic post-stroke shoulder spasticity

Neural Regen Res. 2018 Apr;13(4):673-676. doi: 10.4103/1673-5374.230293.


Post-stroke spasticity is associated with restriction in the range of motion of the shoulder. Reducing muscular dystrophy may help relieve muscular dysfunction in patients with post-stroke shoulder spasticity. Dry needle therapy is a method of needling the trigger points using a syringe needle without the use of a drug. Dry needle therapy is commonly used for pain at the shoulder, neck, waist, and back. In this case study, a 62-year-old male patient affected with cerebral hemorrhage of the right frontal lobe had received rehabilitative treatment for 12 years. However, he still experienced shoulder spasticity. The patient received daily dry needling at the trigger points of infraspinatus, teres minor, posterior deltoid, and pectoralis major on 9 days. After the first and ninth treatment, the Modified Ashworth Scale and the passive range of motion of the shoulder was used to assess the effect of the treatment. The spasticity and range of motion of the shoulder showed obvious improvement. These results indicate that dry needling at the myofascial trigger points can effectively treat chronic post-stroke shoulder spasticity.
