1. The treating clinician will use soft tissue palpation procedures applied to hips, pelvis / buttocks low back and mid back to identify taut and tender regions for manual therapy, e.g., trigger points that the clinician identified during soft tissue palpations.
2. The treating clinician will use soft tissue treatment procedures, e.g., applying precise pressure to trigger points and manual stretching techniques, to relieve taut and tender regions that were identified during soft tissue palpation procedures.
3. The treating clinician will perform high velocity, low amplitude (HVLA) spinal adjustments to restricted areas of the mid back, lower back, and hips regions.

Chiropractic Care is the same as described for the active comparator arm. After receiving chiropractic care, the subject receives radial extracorporeal shockwave therapy (ESWT). The treating clinician places the ESWT probe over the treatment areas in the mid back, low back, and hip regions. At each clinic visit, there are up to six treatment areas for ESWT. At each treatment area, the subject receives 2000 radial pulses at frequency of 10 Hz (single pulse every 100 ms or 10 pulses per second). The intensity of the radial pulses are comfortable for the subjects. Duration of ESWT at each treatment area is 200 seconds or 3.33 minutes.

Chiropractic Care is the active comparator arm / intervention. All subjects will receive chiropractic care.

Before the administration of treatment at each visit, subjects rate their pain on a scale of 0 to 10 with 0 being no pain at all and 10 being worse pain possible. The subjects provide NPRS scores within the context of right now, pain at its best in the past 7 days, and pain at its worst in the past 7 days. At the end of each treatment visit, subjects rate their pain right now on a scale of 0 to 10 with 0 being no pain at all and 10 being worse pain imaginable

1. Before and after the administration of treatment at each visit, subjects perform six squats - moving from a standing position to a squat position. Using an iPad Pro researchers record subjects performing the 3 consecutive squats from a front view and then 3 consecutive squats from a side view. There are 15 seconds between the six squats.
2. Using the Kinetisense software on the iPad Pro, researchers generate a Clinical Biomechanics Report to measure squat performance.
3. The overall score from clinical biomechanics report for the squat test is the primary outcome to assess physical function.
