At Crew Chiropractic I track 3 things with my patients. The first is a posture scan, the second is a nerve scan, and the third is x-rays. I check in and redo the nerve and posture scans every 12 visits. This helps let me and the patient know that what we are doing is working, or maybe I  need to switch something up in their care plan because we aren't getting the expected results. When these scans progress, then I am able to start to recommend more time in between visits, with the end goal being finding a frequency that maintains the results we just worked for.
