Lumbar spinal stenosis is a common degenerative disease in the elderly. Patients are often accompanied by paresthesias and decreased musculoskeletal system functions, resulting in disability and increasing the burden of medical care. The balance and walking ability of such patients are affected by the compressed nerves, so it is necessary to reorganize the nerve sensory systems to compensate for the disability caused by lumbar stenosis. It is necessary to strengthen the training of sensory integration ability, but it has not been Studies have investigated which treatments or surgery can improve sensory integration in patients with lumbar stenosis. Therefore, this study will develop a clinical tool to objectively evaluate sensory integration, quantify the sensory integration ability of patients with lumbar stenosis and neurological claudication; The influence and mechanism of the balance ability.
Objective 1. To develop a sensory integration assessment tool for patients with lumbar stenosis, in order to explore the distribution ratio of sensory system weights between them and healthy elders of the same age without lumbar stenosis under different balance disturbance stimuli. Objective 2. To explore the distribution ratio of sensory system weights and long-term tracking of changes in sensory system weights in patients with lumbar stenosis and neurological claudication who received sensory integration training after spinal decompression surgery.

The sensory integration training of this project will combine virtual reality technology and balance interference treadmill, and manipulate vision, vestibular sense and proprioceptive systems as the main training goals. It is expected to train twice a week for 1 hour, for a total of 6 weeks of training , in order to improve the balance and walking ability of patients with lumbar stenosis and neurological claudication, and to promote the ability of subjects to transfer the effect to daily life after training.
