Alter-G Training on Gait and Balance in Diabetic Neuropathy Patients

Diabetic Peripheral Neuropathy and associated complications became globally serious arousing health problems.

Aim: To evaluate the effect of Antigravity treadmill training on gait performance and functional balance in patients with Diabetic Peripheral Neuropathy.

Design: Single-blinded randomized controlled trial. Setting: Outpatient rehabilitation unit. Population: Sixty-eight eligible participants with Diabetic Peripheral Neuropathy were randomly allocated to Five groups: group-A (100% weight-bearing; n=14), group-B (70% weight-bearing; n=13), group-C (50% weight-bearing; n=14), group-D (30% weight-bearing; n=13), group-E (control group; n=14).

Methods: Participants in study groups A, B, C, and D received moderate intensity (50-70% heart rate reserve) aerobic exercise training program on the antigravity treadmill (AlterG, Inc., Fremont, CA, USA) 3 times/week for 12-weeks. The gait performance (using the dynamic gait index) and the functional balance (using the Berg balance scale) variables were evaluated at 3-time points: baseline (evaluation-1), after 12 training weeks (evaluation-2), and 3 months post-training cessation (evaluation-3).

About this study

Diabetic Peripheral neuropathy is the most common serious diabetes-related complication affecting more than one-third of patients with diabetes especially those with type 2 diabetes. Diabetic Peripheral neuropathy is defined as the existence of clinical indicators of neural dysfunction after excluding other causes in patients with diabetes and is usually affecting the sensory nerves before the motor ones, following the distal to proximal pattern distribution. Type 2 diabetes-related microangiopathy, neural ischemia, and demyelination are the commonly encountered pathophysiological endpoints responsible for Diabetic Peripheral neuropathy-related neural lesions. The Diabetic Peripheral neuropathy-related proprioceptive inputs impairments further predispose patients to frequently disturbed static and dynamic balance as well as impaired gait performance. Controversy existed regarding the efficacy of the weight-support aerobic exercise training on the locomotion, gait, and functional variables in patients with Diabetic Peripheral neuropathy. Researchers initially thought that weight-bearing exercise training is more beneficial in improving physical function than non-weight-bearing exercise training in patients with Diabetic Peripheral neuropathy. Few studies reported non-significant functional effects of the increased weight support, while others reported beneficial effects of the partial weight off-loading aerobic exercise training on the gait, balance, and functional performance in patients with Diabetic Peripheral neuropathy.
