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