Conservative lower back treatment reduces inhibition in knee-extensor muscles: a randomized controlled trial

Chiropractic management of a patient with postoperative lateral retinacular release using a multimodal approach: a case report

“…11 Chiropractic manipulation can alter the mechanics of the hips, spine, and pelvis; and there is also evidence to suggest that sacroiliac joint manipulation may reduce inhibition of the knee extensors muscles. 12 One treatment not explored in this case was the inexpensive elastic patellofemoral sleeve brace. Evidence indicates …”

Effects of Lumbosacral Manipulation on Isokinetic Strength of the Knee Extensors and Flexors in Healthy Subjects: A Randomized, Controlled, Single-Blind Crossover Trial

“…The testing of injured subjects involves consideration of a number of other factors, such as muscle inhibition, that have the potential to show improvement post-SM that are not present in healthy subjects. For example, in 2 studies, Suter and colleagues 6,7 recorded decreases in quadriceps femoris inhibition in subjects with anterior knee pain using the interpolated twitch technique following side-posture, HVLA SI joint manipulation. This concept provides possible insight into the discrepancy between these results and the majority of other studies' findings.…”

“…The anatomical basis for the importance of these levels lies in their innervations of the quadriceps femoris and hamstrings muscle groups via the femoral and sciatic nerves, respectively. Prior investigators 2,6,28,29 have attributed the changes in neural activity post-SM therapy to altered central nervous system (CNS) processing of afferent input from the segmentally innervated structures of the restricted intervertebral joint. It has been further proposed that the perpetual aberrant afferent signals of a fixated intervertebral motion segment are ameliorated by the dynamic stimulus during HVLA SMT.…”

“…The protocol used in this study can be used in future research as a basis to compare the results of normal and injured subjects, and to determine a possible effect of SM on strength in subjects with DOMS and acute postexercise fatigue. Given the prevalence of conditions such as patellofemoral pain syndrome, [5][6][7] further investigation incorporating the experimental design of this study could possibly benefit subject populations with various injuries or neuromusculoskeletal diseases.…”

“…The addition of knee flexion would add to the results of previous experiments which measured the effects of SM on knee extension. [4][5][6][7][8] It was hypothesized that significant differences would be found between the peak torques following high-velocity, low-amplitude (HVLA) SM and the sham manipulation at 5 minutes posttreatment but not at 20 minutes. This postulation was congruent with previous authors' findings that strength-modulating effects of SM do not exceed 10 to 20 minutes.…”
