Brief Summary

Type II-diabetic neuropathy is the most common and correlated problem with diabetes that deteriorates with the passage of time. Balance disorders are also resulting of movement strategy damage, biomechanical and mechanical disorientation. The balance disorder has been reported to be related to abnormal somatosensory feedback, which is utilized in the development of an interior depiction of body motion and position (inner model) in the central nervous system. The Biodex stability system offers a system that can deliver particular hip and ankle postural training strategy with external biofeedback as a monitor to enhance the reduced subclinical limitations of patients with diabetic neuropathy.

Detailed Description

Diabetes mellitus is one of the most common critical illnesses with a higher prevalence all over the world. Diabetic neuropathy is the most common and correlated problem with diabetes that deteriorates with the passage of time. Diabetic neuropathy is a progressive and complex disease, characterized by regular distal deterioration of peripheral nerves which lead to symptoms of sensory loss and pain. During normal situations, somatosensory inputs from the feet and legs participate in the stability of posture. Posture reflex and balance alignment are common findings in diabetic neuropathy because of reduced proprioception and rising time of reflex reactions. Balance disorders are also results of movement strategy damage, biomechanical and mechanical disorientation.

About 20-30% of patients with diabetic neuropathy suffer from neuropathic pains.

Neuropathic complications are prevalent among 39.6% of the diabetic population. Diabetic neuropathy lowers significantly the quality of life and considerably increases health expenses related to diabetes. Diabetic neuropathy patients exhibit stability disorders and are vulnerable to falls even with open eyes. The instability sources in patients with type-II diabetic neuropathy comprise the incapability of the central nervous system (CNS) to integrate properly available information of postural control and a shift of balance strategy from ankle-based to hip-based. Furthermore, a rise in the reliance on visual information and the use of vestibular information change the format of postural control in patients with diabetic neuropathy.

Stability can be referred to as the warmth of a dynamic system to different worries, and local constancy is the sensitivity of the structure to internal distresses, for example, natural fluxes like variation in muscle activity respond to gravity which occurs during stability. The impacts of such natural variations were inspected for assessing diverse measures of postural influence. Multiple studies on diabetic patients by neuropathic postural instability recommend relative shortfalls in their capability to sustain posture and specify higher instability as compared to non-diabetics and positive relations between falling and postural instability.

Moreover, studies of posture instability in diabetic patients with diabetic neuropathy have shown greater scores for postural stability indexes, area of sway, speed, greater ranges of the centre of pressure; increased values of the centre of mass variables and increase of sway power in less stable postures. Awareness and appropriately performing balance and stability training in patients involve comprehensive knowledge of the causes of postural complications. Postural control involves a composite organization that controls the equilibrium and orientation of the body during upright stand.

In addition, posture control involves multiple underlying physiological organizations and dependent upon six contexts: (a) cognitive processing, (b) sensory approaches, (c) movement approaches, (d) dynamics control (e), space orientation and (f) biomechanical task limitations. The sensory afferents sources which seem to participate in postural control comprise proprioception, visual systems, and vestibular. Subclinical and pathological constrictions in patients with diabetic neuropathy are because of context-specific and distinct instabilities like sensory and movement approaches. Reactive movement approaches are helpful for patients in developing multi-joint coordinated movement, and sensory approaches for selecting proper sensory information to control posture. The hip and ankle reactive movement approach reported being helpful to return the equilibrium of the body and keeping the feet in position. When people stand on a rigid surface, the ankle approach maintains balance with little movements in the form of an inverted pendulum. Rehabilitation and reactive movement strategies comprise the patient's exposure to external perturbations which differ in direction, amplitude, and speed. However, few studies have reported the correlation between balance training and external response. These trainings are useful to progress the sensory integration and dynamic balance capabilities of aged adults with a falling history and support for frail aged women in domestic care.

It also has been ideal to balance training at home. In addition, static-standing stability can be trained efficiently through weight-bearing exercise, and a visual guided weight-shifting drill can develop a standing balance mechanism of static balance in diabetic neuropathy patients. Like so, the BIODEX stability system offers a system that can deliver particular hip and ankle postural training strategy with external biofeedback as a monitor to enhance the reduced subclinical limitations of patients with diabetic neuropathy. As these patients are often of old age and have symptoms of instability identical to those of elder people, it is supposed that a balance-training platform with a BIODEX balance system may also improve balance in patients with diabetic neuropathy

Arm && Interventions

Group	Intervention	Description
BIODEX training group	Biodex balance system	These individuals will receive conventional along with postural stability training with biodex balance system which stimulates specific movement patterns or strategies by placing markers on a specific location on-screen grid subject attempted to touch targets nine times using an onscreen cursor manoeuvred by the subject leg on the device platform
Conventional therapy group	conventional exercises	These individuals will perform balance exercises including proprioception exercises, balance board exercises, walking on different surfaces, Wobble board exercise and parallel bars for ambulatory training, range of motion exercises, foot care as a home program (advices).

Primary Outcome Measures

Name	Time	Method
Berg Balance Scale	week 8	The Berg balance scale is used to objectively determine a patient's ability (or inability) to safely balance during a series of predetermined tasks. It is a 14 item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function and takes approximately 20 minutes to complete
Timed up and go test	week 8	The Timed Up and Go (TUG) is a screening tool used to test basic mobility skills of frail elderly patients (60-90 years old). The TUG can be used with but is not limited to, persons with stroke.; 10s Completely independent With or without walking aid for ambulation and transfers; \< 20s Independent for main transfers With or without walking aid, independent for basic tub or shower transfers and able to climb most stairs and go outside alone; \> 30s Requires assistance Dependent in most activities
Functional reach test	week 8	The Functional Reach Test is a single item test developed as a quick screen for balance problems in older adults.; Interpretation: A score of 6 or less indicates a significant increased risk for falls. A score between 6-10 inches indicates a moderate risk for falls
