The effects of dorso-lumbar motion restriction on energy use and center of mass movement during running.

The effects of restricting dorso-lumbar spine mobility on oxygen consumption in runners was investigated, as was vertical movement of the body's center of mass. Thermoplastic casting material was fashioned into a rigid orthosis and used to restrict spinal motion during running. Volunteers ran on a treadmill at 2.

The effects of dorso-lumbar motion restriction on EMG activity of selected muscles during running.

Unlabelled: The effects of restricting dorso-lumbar spine mobility on electromyographic activity of the erector spinae, quadriceps femoris, hamstrings and gastrocnemius muscles in runners was investigated. Thermoplastic casting material was fashioned into a rigid orthosis and used to restrict spinal motion during running. Volunteers ran on a treadmill at 2.

The effects of dorso-lumbar motion restriction on the ground reaction force components during running.

Purpose: The effects of restricting dorso-lumbar spine mobility on ground reaction forces in runners was measured and assessed.

Methods: A semi-rigid cast was used to restrict spinal motion during running. Subjects ran across a force platform at 3.
