Pushes the lumbar spine up and down to decompress the intervertebral disc, reduces lower backpain, and restores the natural S-shaped curve of the spine

Combines traction treatment with vibration massage, hot compress, red and blue light therapy, and EMS massage to enhance blood circulation, oxygen, and nutrient exchange among cells

Swings and twists the waist left and right to stretch the muscles, activates muscles and releases pressure on the lower back

Relieves lumbar strain that leads to stiffness and poor posture, and rapidly alleviates stiffness

Combined stretching and twisting more effective in tackling stiffness.


Applying stretching exercises on educational content are capable to betterment of mental health which result in realizing full potential coping with stress of life, increase the productivity of work and achieving educational goals.*

Sustained trunk axial twisting elicits significant trunk rotational creep. It causes the visual analog scale to have a significant increase, and causes erector spinae muscles to become active longer during anterior flexion as well as extension, which may be linked to the decrease of the tension ability of passive tissues in low back area, indicating a higher risk in developing low back pain..**
