Effects of Antigravity Treadmill Training on Gait and Balance in Patients With Diabetic Polyneuropathy

Aging can be defined as sequential deterioration that occurs in elderly people including weakness, loss of mobility, decline of physical capabilities, increase susceptibility to disease and many other age-related physiological changes .The beginning of old age in most developed countries is about 60 or 65 years old. Diabetes mellitus (DM) and most commonly type 2 DM is one of the most common chronic non-communicable diseases affecting old people in Saudi Arabia which might be resulted from decline in physical activities. Polyneuropathy (PN) and its serious consequences represent the most common complication in diabetic mellitus which could contribute to an increased gait abnormality and risk of falling.

Study Overview

• Status: Completed
• Conditions: Diabetic Polyneuropathy
• Intervention / Treatment: Other: Antigravity treadmill training; Other: Conventional exercise program

Detailed Description

Disability and reduction of quality of life are the largest costs of diabetes and its complications. So taking active intervention to reduce the risk of falls, improve gait performance and improve the quality of life in elderly with DPN is very important. Lower extremity aerobic exercise training via treadmill aiming for improving patients' physical activity levels is an important part in the rehabilitation program to enhance balance and walking functions and reducing the fall risk, .Treadmill training using s low-load walking provided by an emerging technology called lower body positive pressure (LBPP) that effectively reduces body weight could be preferable than other methods of unweighting treadmill because the air pressure is applied uniformly over the lower body. This kind of anti-gravity treadmill is ideal in reducing the formation of pain and pressure points that are common with harness-based unweighting systems. Many other advantages are also associated with this unique type of antigravity technology that could give it the superiority than the other types of unweighting treadmills in enhancing walking performance, reducing the risk of fall and improving quality of life in Saudi elderly people with DPN.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline spatial and temporal gait parameters at 3 months	Spatial and temporal gait analysis will be evaluated for every patient at baseline and 3 months post-intervention by using the 3-D motion analysis system.	Baseline and 3 months post-intervention
Change from baseline postural stability at 3 months	Postural stability assessment by using Balance Biodex stability system measuring (antero-posterior, medio-lateral, and overall stability indices.	Baseline and 3 months post-intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline functional capacity at 3 months	The assessment of functional capacity will be done using Six Minute Walk Test where intensity is moderately higher than daily living activities. Subject will be asked to walk at his own maximal pace from end to end of a 40-meter flat, straight corridor marked every 1 meter with side cones, in order to cover as much ground as possible while maintaining a steady pace without running during the allowed time. No verbal encouragement will be given, and subjects will be informed verbally each 2 minutes of the remaining time. The patients will be allowed to stop, but they can start again, if possible, within the allocated 6 minutes. Distance covered in 6 minutes will be recorded in meter. The longer the distance that will be walked will signify a better performance.	Baseline and 3 months post-intervention
