Early Initiation of a Strength Training Based Rehabilitation After Lumbar Spine Fusion Improves Core Muscle Strength

The training group performed rehabilitation program twice per week over 9 weeks. The group commenced rehabilitation 3 weeks after the surgery. During the phase one training (week 1 to week 5), the isometric exercises were preformed on the trunk extension, flexion and lateral flexion muscles. During the phase 2 (week 6 to week 9), the exercises were performed on the strength machines and duration of the exercises were maintained and prolonged to 30 seconds. The leg adduction and hip extension exercises were added. The patients were instructed to perform abdominal bracing (IAP) and maintain the neutral position of their lumbar spine before and during the exercises.
