Objective: Loss of disc height is commonly associated with chronic low back pain (CLBP). Isolated lumbar extension (ILEX) exercise for the lumbar extensors is recommended to treat CLBP and is suggested such exercise might promote disc healing and regeneration. This study examined a 12-week ILEX intervention on indirect determination of disc height...

Objectives: Current protocols for resistance training in space flight are hindered by size, mass, noise, vibration and cost, and potentially still lack efficacy. The purpose of the present study was to examine the muscle activation and force output for con-tralateral limb resisted training compared to traditional resistance training with a view tow...

Indirect measurement of disc hydration can be obtained through measures of spinal height using stadiometry. However, specialised stadiometers for this are often custom-built and expensive. Generic wall-mounted stadiometers alternatively are common in clinics and laboratories. This study examined the reliability of a custom set-up utilising a wall-m...

Chronic low back pain (CLBP) is a multifactorial condition with a variety of symptoms; one being abnormal gait. The lumbar spine and its musculature are important in controlling gait and in CLBP the lumbar extensors are often deconditioned. Because of this specific isolated lumbar extension exercise is often recommended. It was therefore of interes...

Background Chronic low back pain is a multifactorial condition with a variety of dysfunctions; one being gait variability. The lumbar spine and its musculature are involved during gait and in chronic low back pain the lumbar extensors are often deconditioned. It was therefore of interest to examine relationships between lumbar kinematic variability...

Despite manufacturer claims that athletic socks attenuate force during exercise, no device exists to assess this. Therefore, this study outlines the development of a custom-built impact-testing device for assessing the cushioning properties of socks. The device used a gravity-driven impact striker (8.5 kg), released from 0.05 m, which impacted a no...

One of the aims of the sock/shoe unit is to reduce the severity of impact forces on the lower extremity although the injury prevention potential of the sock through the attenuation of impact force has yet to be established. This study aims to determine the effect of athletic socks and a sock/shoe unit on peak impact force, time to peak impact force...

Study design: Randomized controlled trial. Objective: To compare the effects of full range of motion (ROM) and limited ROM isolated lumbar extension exercise upon full ROM lumbar extension strength, ROM, perceived pain, and disability. Summary of background data: Limited ROM is common in chronic low back pain as is lumbar extensor deconditioni...
