Physiotherapy can play an adjunctive role in the treatment of lumbar disc herniation. First, various thermal and electrical stimulation therapies in physical therapy can relieve pain and can play a role in symptomatic treatment. Secondly, heat therapy, short wave, ultra short wave, infrared and other physiotherapy means have the effect of promoting inflammation subsidence and absorption, which can reduce the inflammatory response of lumbar disc herniation. Furthermore, physiotherapy can loosen adhesions caused by various reasons, especially for the recovery of patients with lumbar disc herniation who have undergone surgery. In addition, untimely treatment of lumbar disc herniation can cause numbness of the lower limbs and muscle atrophy due to prolonged nerve root compression. Low and medium frequency electrotherapy can stimulate excitable nerves, promote nerve repair and induce sensory recovery.
