Exercise and Neuropathy: Systematic Review with Meta-Analysis.

Peripheral neuropathies, nerve conditions that cause pain, numbness, and balance problems, are common and hard to treat with medications alone. This systematic review with meta-analysis updated a 2014 review, asking whether exercise helps people with neuropathy of different causes. Researchers found 41 randomized controlled trials meeting their criteria, with 20 included in the quantitative pooled analysis, and rated study quality as moderate to high overall. Most evidence came from diabetic peripheral neuropathy (27 studies) and chemotherapy-induced peripheral neuropathy (9 studies), with only five studies covering all other causes combined.

For diabetic neuropathy, pooled effects favored exercise for balance, functional mobility, nerve conduction velocity, and blood sugar control (HbA1c), with standardized mean differences ranging from 0.27 to 2.00. For chemotherapy-induced neuropathy, effects favored exercise for balance, quality of life, and symptoms, with differences of 0.43 to 0.75. Evidence for other neuropathy causes remains too limited to draw firm conclusions.

If you live with peripheral neuropathy, nerve damage that can cause pain, numbness, or balance trouble, you know how disruptive it can be, and how few proven treatments exist. This review pulled together 41 randomized controlled trials testing exercise programs against inactive control groups, with 20 of these studies combined in a formal statistical analysis.

The quality of these studies ranged from moderate to high. The strongest evidence was for diabetic peripheral neuropathy, based on 27 studies, and chemotherapy-induced neuropathy, based on nine studies. For diabetic neuropathy, exercise groups showed better balance, walking ability, nerve signal speed, and blood sugar levels compared to non-exercising groups.

For chemotherapy-related neuropathy, exercise groups showed better balance, quality of life, and fewer neuropathy symptoms. For all other causes of neuropathy, only five studies existed, too few to draw solid conclusions. The review's authors note that combining balance-focused training, called sensorimotor training, with cardio-type exercise appeared most beneficial for diabetic neuropathy, while balance training stood out most for chemotherapy-related neuropathy.

Since this is a review of existing trials rather than a new study, its conclusions depend on the quality and consistency of the original research.

This PRISMA-guided systematic review and meta-analysis (PROSPERO registered) updated a 2014 review on exercise interventions for peripheral neuropathy. Of 41 randomized controlled trials meeting inclusion criteria, 20 were suitable for quantitative pooling; overall study quality was rated moderate to high, though risk of bias across the full evidence base is not detailed beyond this summary rating. Evidence density was uneven: diabetic peripheral neuropathy (DPN) dominated with 27 studies, chemotherapy-induced peripheral neuropathy (CIPN) contributed nine, and all other neuropathy etiologies combined offered only five studies.

For DPN, standardized mean differences favoring exercise ranged from 0.27 to 2.00 across static balance, Berg Balance Scale, timed-up-and-go, peroneal and sural nerve conduction velocity, and HbA1c, suggesting combined endurance and sensorimotor training as the most supported approach. For CIPN, effects of 0.43 to 0.75 favored exercise for static balance, quality of life, and neuropathic symptoms, with sensorimotor training identified as the key component. Given the wide range of effect sizes and the small number of trials for non-DPN, non-CIPN neuropathies, confidence in generalizing beyond these two conditions remains limited.

Heterogeneity in intervention type, duration, and outcome measures across the pooled studies was not fully characterized in the abstract, warranting cautious interpretation of the aggregated effect sizes.
