A single bout of moderate intensity lumbar extensor muscle exercise.

Disc Degeneration

Low Back Pain

The exercise protocol consists of 1 set of 20 repetitions (range 15-25 reps) at a rate of 5 seconds/repetitions with a starting weight of 60-80% of their computerized strength score. Patients will be instructed to target an exertion level of 7/10 on the Borg Rate of Perceived Exertion (RPE) scale within their available passive ROM range into flexion-extension
