The effect of Lumbosacral support on spinal muscle fatigue
Authors
Abstract
Abstract Background: Wearing back support is of great importance in helping muscles action in heavy works. Objective: To evaluate the effect of lumbosacral support on the degree of spinal muscle fatigue in normal persons. Methods: The study was conducted on 52 normal females as "case-control" group using Isostation B-200 unit. Three isometric contractions with maximum effort in flexion and extension were applied for each case in the first session without using back support. Then, fatigue exercise was performed with 50% of maximum muscle power in flexion and extension and the maximum isometric power was again measured. On the next day, the same procedure was performed using back support. Findings: Increase of the average of torque, power, maximum and average angular speed was significant while wearing back support (P<0.05). Also, the mean of maximum torque and maximum angular speed in last repetitions, with and without back support were significantly decreased in comparison with first repetitions (P<0.05). Conclusion: Since using lumbosacral back support will cause improvement in speed of repeated motions, less function and delayed fatigue of paravertebral muscles, the use of back support during working hours in heavy works is highly recommended.
