Forward bending, twisting movements or exposure to vibration while driving tractors for long hours predispose the wheat and rice farmers to various physical stresses. Tissue stress induced by heavy load carrying may afect the spinal disc and the damage may be in both mechanical and biological pathways. Excessive bending injures the ligament of neural arch and additional twisting or lateral bending could result in disc prolapsed. Disc tissue can also be injured through prolonged working hours causing fatigued. Modern machinery like tractors, harvesters etc. may overtly seem to ease the work but in fact they only reduce the workforce while putting the farmer to additional disadvantages like excessive whole body vibration. Vibration is transmitted across the body through seat or feet while riding the vehicle. Walker-Bone and Palmer in their study on MSDs in farmers and farm workers concluded that tractor drivers are especially at high risk of low back pain. Heavy loading of joints and whole body vibration are the important risk factors associated with occurrence of low back pain [10].
