Immediate effects of dry needling on spasticity-related parameters in the wrist and elbow of patients after a stroke: a quasi-experimental feasibility study.

Background/Aims: Dry needling is widely used to treat myofascial pain and related musculoskeletal conditions. Recently, the use of dry needling for the management of post-stroke spasticity has been proposed. The aim of this study was to evaluate the immediate effect of dry needling of spastic muscles on pain, spasticity, and pain pressure threshold in the elbow and wrist muscles of patients who have had a stroke. Methods: This quasi-experimental, pre–post design feasibility study implemented dry needling in wrist or elbow flexors. Outcome measures evaluated muscle spasticity using the Modified Modified Ashworth Scale, pain pressure threshold and range of motion. Results: A total of eight participants (seven men and one woman) were included in the study. The average age was 57.00 ± 13.88 years. The Modified Modified Ashworth Scale scores decreased from 1.81 ± 0.84 to 1.25 ± 0.46 in the elbow flexors (P=0.066) and from 1.86 ± 0.69 to 1.29 ± 0.49 in the wrist extensors (P=0.046). Range of motion increased in the elbow, and there was a statistically significant increase in the range of motion in the wrist (P=0.027). Pain pressure threshold also increased statistically significantly in muscles related to the wrist and elbow (P=0.043 and P=0.035 respectively). Conclusions: Dry needling may decrease spasticity, increase range of motion and pain pressure threshold in treated muscles and improve functional gains in the spastic limb. Further, more extensive studies are essential to assess the use of dry needling in managing post-stroke spasticity. Implications for practice: Physiotherapists can use dry needling in spastic muscles when treating patients who have had a stroke. [ABSTRACT FROM AUTHOR]
