简要总结
An experimental study, which will aim to investigate the acute effects of unloading maneuvers during an intermittent spinal flexion protocol on changes in trunk mechanical and neuromuscular properties.
详细描述
Our experimental study will include 30 participants. All participants will complete a 60-min intermittent spinal flexion protocol. During rest periods within the protocol, the participants from the intervention group will perform unloading maneuvers for the lumbar spine. Measurements of trunk mechanical and neuromuscular properties. will be performed prior to and following the 60-min protocol.

排除标准
- •History of chronic low back pain
- •Episode of acute low back pain
- •Hip injury in the past six months
- •Previous spine, pelvis or hip surgery
- •Hypermobility, diagnosed with the Beighton score

研究组 & 干预措施
Control group
Adult participants completing only the spinal flexion protocol
Intervention group
Adult participants performing unloading maneuvers in between the spinal flexion protocol
干预措施: Unloading maneuvers (Other)
结局指标
主要结局
Change in muscle stiffness
时间窗: 90 minutes
Muscle stiffness will be measured using ultrasound-based shear wave elastography during prone lying and forward stooping. Erector spinae and multifidus muscle stiffness will be expressed as the shear modulus value in kilopascals.
次要结局
- Change in range of motion(90 minutes)
- Change in trunk extension maximal strength(90 minutes)
- Change in seated spinal height(90 minutes)
- Change in lumbar lordosis angle(90 minutes)
