Efficacy of exercise on balance, fear of falling, and risk of falls in patients with diabetic peripheral neuropathy: a systematic review and meta-analysis

Effects of exercise therapy on diabetic neuropathy: A systematic review and meta-analysis

OBJECTIVE

To evaluate the effects of exercise therapy on neuropathic symptoms, signs, psychosocial aspects, and physical function in people with diabetic neuropathy (DN).

METHODS

A search in PubMed, Web of Science, Physiotherapy Evidence (PEDro), and Cochrane databases was performed from inception to Invalid Date NaN, . Randomized clinical trials (RCTs) were selected in patients with DN comparing exercise therapy with a control group. The studies' methodological quality was assessed with the PEDro scale. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the overall quality.

RESULTS

Eleven RCTs (n = 517 participants) were included. Nine studies showed high methodological quality. Mean (MD) and standardized mean differences (SMD) were observed in favor of exercise therapy for symptoms (MD = -1.05; confidence interval 95% = -1.90 to -0.20), signs (SMD = -0.66; confidence interval 95%= -1 to -0.32), and physical function (SMD = -0.45; confidence interval 95% = -0.66 to -0.24). No changes were found in psychosocial aspects (SMD = -0.37; confidence interval 95% = -0.92 to 0.18). The overall quality of evidence was very low.

CONCLUSION

The quality of evidence suggesting that exercise therapy provides short-term benefits in neuropathic symptoms, signs, and physical function in patients with DN is very low. Furthermore, there were no effects found on psychosocial aspects.

Balance Problems in the Elderly with Diabetes Mellitus: A Literature Review

Diabetes mellitus (DM) is a syndrome of chronic metabolic disease which leads to all kinds of complications. Elderly people with DM have significantly higher fear of falling and balance problem scores as compared to those who did not have DM. This literature review aims: (1) to determine the risk factors for balance disorders in the elderly population with DM, (2) to describe valid and reliable balance measurement tools in the elderly population with DM, and (3) to describe the nonpharmacological management in dealing with balance disorders in the elderly population with DM. Several risk factors that cause balance disorders in the elderly with DM are related to complications of the disease they suffer, such as diabetic peripheral neuropathy, decreased sensory abilities, decreased motor skills, and decreased cognitive condition of the elderly with DM. Measuring instruments that can be used in the elderly population with DM to assess balance include the Mini-Balance Evaluation Systems Test, the Berg Balance Scale, and computerized measuring instruments with center of pressure analysis. Several nonpharmacological interventions are suggested in overcoming balance problems in the elderly with DM, including a combination of balance exercise and gait training, strength or resistance training, aquatic exercise, tai chi, yoga, technology-based exercise, electrotherapy, use of insoles, and whole-body vibrations.

Therapeutic Interventions to Improve Static Balance in Type 2 DiabetesMellitus: A Systematic Review and Meta-Analysis

INTRODUCTION

Diabetes mellitus (DM) is a metabolic disorder characterized by an abnormal increase in blood glucose levels resulting from insulin secretion and/or dysfunctional activity that can lead to several serious complications in addition to decreased postural balance.

OBJECTIVE

This study aimed to identify and analyze the main interventions used to improve static balance in patients with DM.

METHODS

For the selection of articles, a bibliographic search was performed using PubMed, Scopus, Web of Science, Embase, and Cochrane databases. Only clinical trials that investigated the effect of training on static balance in adults with type 2 DM were selected, and 34 studies were included.

RESULTS

The search resulted in the identification of 2681 articles, and of these, 31 were eligible for the study. The identified interventions were proprioceptive, aerobic, resistance training on platforms, in virtual reality, and Tai Chi. The main results obtained were an increase in time in the one-leg stance, Romberg test, and tandem position, a significant increase in the Berg Balance Scale score and balance index, and a reduction in the variables of postural sway.

CONCLUSION

There are a variety of effective training methods for improving static balance, and the choice of intervention to be applied goes beyond proven effectiveness, depending on reproducibility and/or financial cost.

Wearable Sensor for Assessing Gait and Postural Alterations in Patients with Diabetes: A Scoping Review

Background and Objectives: Diabetes mellitus is considered a serious public health problem due to its high prevalence and related complications, including gait and posture impairments due to neuropathy and vascular alterations and the subsequent increased risk of falls. The gait of patients with diabetes is characterized by alterations of the main spatiotemporal gait parameters such as gait velocity, cadence, stride time and length, which are also known to worsen with disease course. Wearable sensor systems can be used for gait analysis by providing spatiotemporal parameters and postural control (evaluated from the perspective of body sway), useful for investigating the disease progression. Thanks to their small size and low cost of their components, inertial measurement units (IMUs) are easy to wear and are cheap tools for movement analysis. Materials and Methods: The aim of this study is to review articles published in the last 21 years (from 2000 to 2021) concerning the application of wearable sensors to assess spatiotemporal parameters of gait and body postural alterations in patients with diabetes mellitus. Relevant articles were searched in the Medline database using PubMed, Ovid and Cochrane libraries. Results: One hundred and four articles were initially identified while searching the scientific literature on this topic. Thirteen were selected and analysed in this review. Wearable motion sensors are useful, noninvasive, low-cost, and objective tools for performing gait and posture analysis in diabetic patients. The IMUs can be worn at the lumber levels, tibias or feet, and different spatiotemporal parameters of movement and static posture can be assessed. Conclusions: Future research should focus on standardizing the measurement setup and selecting the most informative spatiotemporal parameters for gait and posture analysis.
