Abstract
STUDY DESIGN: Prospective, randomized.
OBJECTIVES: To determine the difference in rate and maintenance of improvement of pain and disability for Dry Needling (DN) compared to Dry Needling with Intramuscular Electrical Stimulation (DN/IMES), in Myofascial Pain Syndrome (MPS).
BACKGROUND: DN and neuromuscular electrical stimulation (NMES) have been shown to be efficacious in treating MPS. DN/IMES for MPS treatment has not been studied extensively, but initial results are promising.
METHODS: Forty-five subjects were randomly assigned to the DN (n = 25) or DN/IMES (n = 20) group. Both groups received six consecutive weekly treatments and completed NDI and NPRS questionnaires (week 0, 3, 6, and 12).
RESULTS: Both DN and DN/IMES groups showed significant improvement between weeks 0-6 on NDI (p = 0.008 and 0.00002, respectively) and NPRS scores (0 = 0.017 and p = 0.018, respectively). DN/IMES group showed significant within group changes on the NPRS between weeks 0-3 (p = 0.029). No changes were noted in the DN or DN/IMES groups between week 6-12 on NDI (p = 0.497 and p = 0.714, respectively) or NPRS (p = 0.801 and p = 0.164, respectively).
CONCLUSION: DN and DN/IMES demonstrated improvement and maintenance in disability and pain for 6 weeks. No differences in improvement of disability or pain existed between the groups at week 6 or 12.
