Sensory Integration Therapy Training in Patients With Lumbar Spinal Stenosis

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental<br>sensory integration training exercise for improving balance and walking ability of patients with lumbar stenosis and neurological claudication. | Other: virtual reality walking training<br>* 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postural balance: Mean velocity | The postural balance measurements are performed by using a force platform. The data from the force platform is used to calculate the mean velocity (unit: cm/s). | 1 year | 
| Postural balance: Mean distance | The postural balance measurements are performed by using a force platform. The data from the force platform is used to calculate the mean distance (unit: cm). | 1 year | 
| Postural balance:Ｍean frequency | The postural balance measurements are performed by using a force platform. The data from the force platform is used to calculate the mean frequency (unit: Hz). | 1 year | 
| Postural balance: Ellipse area | The postural balance measurements are performed by using a force platform. The data from the force platform is used to calculate 95% confidence ellipse area (unit: cm^2). | 1 year | 
| Functional assessment: Walking speed | Functional assessment is a process that allows for the identification of disability. The data from the functional assessment is used to calculate walking speed (unit: m/s). | 1 year | 
| Functional assessment: Walking distance | Functional assessment is a process that allows for the identification of disability. The data from the functional assessment is used to calculate walking distance (unit: m) | 1 year | 
| Functional assessment: Duration | Functional assessment is a process that allows for the identification of disability. The data from the functional assessment is used to calculate the duration it took to complete the test (unit: s). | 1 year | 
| Muscle activities | Electromyography is a technique for evaluating and recording muscle activity. The data from electromyography is used to calculate a normalized value (unit: ratio). | 1 year | 
| Kinematic variables: Joint angles | A motion capture system is used to measure the joint kinematics. The data is used to calculate joint angles (unit: degree). | 1 year | 
| Kinematic variables: Center of mass | A motion capture system is used to measure the joint kinematics. The data is used to calculate the displacement of the center of mass (unit: cm). | 1 year |
