Combined effects of strength and balance training versus aerobic training on balance, neuropathy symptoms and quality of life in patients with diabetic peripheral neuropathy

Abstract

AbstractBackgroundDiabetic peripheral neuropathy (DPN) occurs in >50% of diabetic patients and is a high risk‐factor of balance problems and risk of falls. Impaired balance can lead to reduced function, which has a detrimental effect on patients' quality of life. Structured strength and balance training can result in sustained improvements in muscle strength, coordination, balance, functional status and quality of life.ObjectiveTo determine the combined effects of strength and balance training versus aerobic training on balance, severity of symptoms of DPN, and quality of life in patients with DPN.MethodsThis double blinded, two arm parallel design Randomized Clinical Trial. The study was conducted from March to December 2020 in the AIMS diabetic center Peshawar, Pakistan. Participants were selected through convenience sampling technique and randomly allocated into strength plus balance and aerobic training groups. Type 2 diabetic patients of both sexes, aged 40 to 80 years, with a Toronto neuropathy score ≥6 recruited, while patients with ulceration/infection of feet, medical/Surgical conditions, and non‐ambulatory patients were excluded from this study. Intervention was applied 3 days a week for 8 weeks. The Toronto clinical neuropathy system was used to assess neuropathy severity, SF‐36 to assess quality of life and the Berg balance scale was used for assessment of balance. Assessment was done at the baseline and after 8 weeks of intervention using SPSS. Version 22 was used for analysis.ResultsThe mean age of the participants was 60.80 ± 9.73. Between group analysis, which showed were statistically insignificant for neuropathy severity, balance and all domains of quality of life (p‐value >0.05) except SF‐36 General Health Perception Score, with Mean ± SD of 62.50 ± 7.54 in group A versus Mean ± SD of in group B 60.00 ± 15.98 (p‐value = 0.05). Within group analysis showed statistically significant results for neuropathy severity, balance and all domains of quality of life (p‐value<0.05).ConclusionThis study concluded that there is a statistically significant effect of structured balance and strength training and aerobic training on severity of DPN, balance and quality of life. But there was no statistically significant difference in improvement between the two intervention groups.
