The Effect of Needle Placement on Muscle Stiffness, Gait, Balance, Pain and Functional Outcomes in Individuals With Injury to the Ankle and/or Hindfoot

The purpose of this randomized controlled trial is to assess the effect of DN at either the site of the identified myofascial trigger point/s (MTrP) of in the same muscle, but away from the MTrP site/s in individuals with ankle and/or hindfoot injury. Assessments will be of self-reported outcomes, self-reported pain, gait, balance, muscle stiffness, and pain pressure threshold. The secondary purpose of this study is to determine the validity of dry needling specific muscles of the lower extremity based upon needle placement, location relative to anatomical structures and accuracy of needle placement in muscle using ultrasound imaging.
