“Effects of Two Different Dry-Needling Techniques for Low Back Pain”
Although dry-needling with or without manipulation has shown to be a useful technique to reduce pain in patients with low back pain (LBP), it is unclear which of these two dry-needling techniques would have a greater effect on the lumboscaral multifidus (LM) muscle activation, which is essential in LBP rehabilitation. Therefore, the purposes of the study are: 1) to investigate whether or not dry-needling would change muscle activity of the LM muscles in asymptomatic healthy adults and in individuals with LBP, respectively, and 2) to compare the effects of two dry-needling techniques on LM muscle activation and pressure pain threshold (PPT) in asymptomatic healthy adults and individuals with LBP, respectively.
Procedure - Dry needling
For the needle manipulation technique, the needle will be pulled in and out (sparrow pecking) and redirected in small angles (coning) for 5-10 seconds. For the in situ technique, the needles will stay (in situ) in the left and right lumbar multifidus muscles for 10 minutes after the insertion of the needle.
