Effects of Unloading Maneuvers During Intermittent Spinal Flexion on Trunk Function in Adult Men Aged 30 to 55

What this Trial Is About

This research aims to understand how unloading maneuvers affect trunk mechanical and neuromuscular properties during repeated bending of the spine. The study will include 30 adult male participants whose jobs involve a mix of sitting and standing. The goal is to observe changes caused by spinal flexion and unloading techniques in a controlled setting. Participants will undergo a 60-minute spinal flexion protocol repeatedly with rest periods. Those in the intervention group will perform specific unloading maneuvers during these rests, including self-traction on a box for five seconds and standing trunk extension for eight seconds, repeated twice at each rest. The control group will complete the spinal flexion without these maneuvers. Before and after the 60-minute protocol, researchers will measure various trunk properties such as muscle stiffness, range of motion, seated spinal height, lumbar curve angle, and maximal strength during trunk extension. The study will monitor these changes over 90 minutes to assess the immediate impact. Participants progress and responses will be carefully observed to gather detailed mechanical and neuromuscular data.
