Below outlines the criteria that each patient must accomplish before allowed to complete the phase 2 exercises. At times, some phase 2 exercises may be given when a patient has not met this criteria. But rarely, will a patient be given the entire cuff program and the big 4 without meeting this criteria. This is based on anecdotal evidence of how best to prevent injury.

  1. Able to engage the primary core muscles without compensatory firing or pain in non-weight bearing (supine or prone)
  2. Able to engage the primary core muscles without compensatory firing or pain in static weight bearing positions (standing)
  3. Core Endurance and Ratio Testing has been completed[1] [2][3]
  4. The Big 4 exercises (or modifications of each one) are tolerated for at least a single hold of 8 seconds[4]
