Dry Needling for Plantar Fasciitis: A Literature Review
August 10, 2016
It was with interest and some concern that we read the study by Cotchett et al1 published in the August 2014 issue of Physical Therapy titled “Effectiveness of trigger point dry needling for plantar heel pain: a randomized controlled trial.” While the authors reported statistically significant differences in first-step pain and foot pain in favor of trigger point dry needling over sham dry needling, it appears that the actual palpatory methods used by Cotchett et al1 to identify the location of the target trigger points, and therefore the entry point, angulation, and depth of needle insertion, have not yet been found to possess accurate diagnostic validity or acceptable intra- or inter-examiner reliability for muscles in the foot or lower leg. Therefore, the results of the Cotchett et al1 study, including the reported frequency counts of myofascial trigger points in specific foot intrinsic and lower leg muscles, should be questioned, or at least viewed cautiously. There are several original trials, literature reviews and meta-analyses that support our contention on this issue.
