Effectiveness Of Lee Silverman Voice Treatment (LSVT) BIG In Improving Balance And Gait In Patients With Diabetic Neuropathy In Dervan: A Randomized Controlled Trial

Title - Effectiveness of Lee Silverman Voice Treatment (LSVT) BIG in Improving Balance and Gait in Patients with Diabetic Neuropathy in Dervan: A Randomized Controlled Trial

INTRODUCTION

Approximately 830 million people, worldwide suffer from diabetes, making it a serious health issue. One of its most complications is Diabetic neuropathy, which affects over 50% of people with diabetes. In India, diabetic neuropathy is common, however, its occurrence differs considerably across multiple populations, with estimates ranging from 9.6% to 78%.

Diabetic neuropathy (DN) condition is one of the leading causes of falls in many people with neurological conditions, considerably affecting balance and gait. Lower limb proprioception, cutaneous sensation and muscle stretch reflexes are greatly affected by this condition. These functions are necessary for detecting balance problems and initiating corrective actions. Therefore, such population are at greater risk of balance problems and falls.

The progression of DPN can have a significant impact on a person’s daily life. In the early stages the symptoms may be mild or barely noticeable. But, as the condition advances, people often struggle with sensory and motor impairments affecting their mobility and overall well-being.

Physiotherapy plays an important role in controlling DN by addressing issues like neuropathic pain, muscle weakness, gait instability, and balance issues. Balance issues due to proprioceptive deficiencies and weak ankle muscles are frequently observed. To enhance postural control and coordination, multisensory training, single-leg stance exercises, and weight-shifting drills are observed to be beneficial.

In a randomized clinical trial, Khashayar(2015) compared LSVT BIG with a general exercise program and found significant improvements in balance, gait speed, and postural stability in PD patients. Enhanced weight-shifting ability, increased stride length, and improved reaction times, were also observed all of which are crucial for preventing falls. In conclusion, LSVT BIG therapy proved to be an effective intervention for managing balance deficits in PD, helping individuals reduce fall risk, improve mobility, and maintain independence.

AIM OF THE STUDY-

To evaluate the effectiveness of LSVT BIG in improving balance and gait in patients with diabetic neuropathy.

OBJECTIVE OF THE STUDY –

To compare the effectiveness of LSVT BIG and Conventional Physiotherapy on balance and gait among DN patients.

NEED OF THE STUDY

LSVT BIG is a high-amplitude movement therapy originally developed to improve motor function, balance, and gait. Given the similarities between Parkinsonian gait disturbances and the gait impairments seen in diabetic neuropathy, such as reduced stride length, slow walking speed, and postural instability, LSVT BIG may offer potential benefits for improving motor control and balance in these patients.

Unlike traditional rehabilitation, which often focuses on isolated muscle groups or balance strategies, LSVT BIG encourages whole-body movements that may contribute to improvements in coordination, step length, and walking speed.

This study can prove essential to evaluate whether LSVT BIG exercises can serve as an effective physiotherapy intervention for improving balance and gait in patients with DN. Findings could contribute to clinical guidelines for DN rehabilitation, helping develop targeted interventions to improve patient outcomes.

CLINICAL IMPLICATION-

LSVT BIG can be incorporated into standard physiotherapy regimens for diabetic neuropathy to improve balance and gait.

Improved postural control and gait may reduce the risk of falls in patients with diabetic neuropathy, especially in the elderly population.

The study provides clinicians with evidence to justify the use of LSVT BIG beyond its traditional Parkinson’s population.
