Randomized Controlled Trial
Lidocaine Needling in Myofascial Pain Syndrome for Palliative Oncologic Care: A Randomized Clinical Study.
Background: Physical pain is highly prevalent and impacts the well-being of patients with advanced oncologic disease. Although myofascial pain syndrome (MPS) can be one of the components of pain in cancer patients on palliative care (PC), so far there is no evidence about the benefit of treatment with 1% lidocaine needling. Objectives: To evaluate the efficacy of MPS treatment with injection of 1% lidocaine on the reduction of pain in cancer patients on PC. ⋯ After 72 hours, there was a reduction in referred pain intensity (p < 0.001) and an increase in pressure threshold (p = 0.007) in the intervention group (IG), with no difference in the control. The frequency of individuals who reduced the doses and/or classes of pain medications was higher in the IG (p = 0.011). Conclusion: One percent lidocaine needling in TPs was an effective therapy for pain reduction in MPS.
