Peak torque of lumbar and hip extensors in females with LBP

What is it about?

This study displayed that there was no effect of lumbar spondylosis on eccentric torque of lumbar and hip extensors muscles. However, it decreases the concentric torque. So, clinicians must concentrically strengthen the back and hip extensor muscles during designing of rehabilitation program for patients with lumbar spondylosis.

Why is it important?

Many studies involving trunk muscle strength testing have used the isometric strength testing. However, little is known about the eccentric and concentric muscle strength of patients with LBP. The eccentric contraction plays a significant role in the activities of daily living and exercise, it occurs when the external force is greater than the internal force of the muscle, for instance, in deceleration of the body during walking, running, and lifting. Therefore, this study was conducted to assess the eccentric and concentric peak torque of lumbar and hip extensors muscles in patients with LBP due to lumbar spondylosis.
