Statement of the Problem:
Trigger points (TrPs) can alter activation pattern and can become painful. Trigger points in the lower
quarter are under-investigated. Latent TrPs in the vastus lateralis (VL) and vastus medialis (VM) may modify knee kinematics possibly
resulting in pathologies such as patellofemoral pain syndrome or knee osteoarthritis. Active TrPs in the VL and VMmay refer pain to
the knee. The sensitivity of TrPs is measured with the pressure pain threshold (PPT) and has been found to be reliable. Dry needling
(DN) is a recommended treatment for TrPs. Post-treatment soreness lasting up to three days has been reported. Radial extracorporeal
shockwave therapy (rESWT) is a relatively new treatment for TrPs. The aim of this study is to compare the short-term effects of DN
and rESWT on the PPT of latent TrPs in the VL and VM.
Methodology & Theoretical Orientation:
A pilot randomized control study, with three groups DN, rESWT, and control, was
conducted. The treatment sessions were undertaken over a week was the PPT and was recorded before treatment. Moreover, two
follow-up sessions occurred which was PPT which was also recorded.
Findings:
DN and rESWT both improve the PPT in the VL and VM. DN showed a greater improvement one week after treatment,
but there was an increase in TrP sensitivity during treatment, possibly due to post-treatment soreness (p<0.01). rESWT, on the other
hand, has less of an improvement than DN but did not demonstrate any transient adverse effects (p<0.01).
Conclusion & Significance:
DN and rESWT can improve the sensitivity of TrPs in the thigh. However, rESWT does not cause any
post treatment soreness. Further investigation is needed to determine the medium-term effects of DN and rESWT on the PPT in the
VL and VM, as well as other muscles responsible for stabilizing the knee..
