effect of trigger point injection on lumbosacral radiculopathy source

conclusions results show that trigger point injection therapy in patients suffering from chronic lumbosacral radiculopathy with trigger points can significantly improve their recovery, and conservative therapy may not be adequate. results out of 98 patients, 64 had trigger points. thirty-two patients were assigned to each group. pain scores (mean ± sd) in tp group was 7.12 ± 1.13 and in n group was 6.7 ± 1.16, p = 0.196. following the treatment, pain scores were 2.4 ± 1.5 in tp group and 4.06 ± 1.76 in n group p = 0.008. slr test became negative in all patients in tp group but only in 6 (19%) patients in n group, p = 0.001. background active muscular trigger points (amtps) presenting with radiating pain can interfere in diagnosis and treatment of patients suffering from lumbosacral radiculopathy. objectives we aimed to diagnose and evaluate the trigger point therapy on the outcome of pain in patients with lumbosacral radiculopathy. materials and methods a total of 98 patients were enrolled suffered with chronic pain andlumbosacral radiculopathy at l4-l5 and l5-s1 who were candidates of non-surgical management. all patients received conservative modalities, including bed rest, non-steroidal anti-inflammatory agents (nsaid), and physiotherapy. these treatments continued for a week. patients were examined for the presence of trigger points in their lower extremities. those who had trigger points were divided into 2 groups (tp and n). patients in tp group underwent trigger point injection therapy. no further therapy was done for the n group. pain scores and straight leg raise (slr) test in both groups were collected and analyzed on the seventh and 10th days of the therapy. results were analyzed by paired t test and chi-square test.
