Abstract

[Purpose] This study examined the effects of a ball-backrest chair combined with an accelerometer on the pain and trunk muscle endurance of a computer worker with low-back pain (LBP). [Subject and Methods] A 36-year-old male with a flat back who complained of LBP at the L3-5 level was the subject. He used the ball-backrest chair when working at a computer for 1 week. [Results] After using the ball backrest, the trunk extensor and flexor muscle endurance times had increased compared with the baseline and the VAS score had decreased from 7 to 4. [Conclusion] Combining exercises with information on motion is a useful common treatment approach for improving trunk muscle endurance in LBP.

Keywords: Ball-backrest chair; Biofeedback; Trunk muscle endurance.
