Quick answer: Diabetic peripheral neuropathy (DPN) affects up to half of people with diabetes and significantly increases fall risk — research shows people with DPN can be up to 20 times more likely to fall than age-matched people without diabetes. Foot drop can develop when neuropathy affects the peroneal nerve, making gait support an important safety consideration.
How Common Is Diabetic Peripheral Neuropathy?
Diabetic peripheral neuropathy affects up to 50% of people with diabetes, making it one of the most common causes of nerve-related foot and gait problems. (Source: Frontiers in Endocrinology)
Why DPN Dramatically Increases Fall Risk
Research on fall risk in diabetic peripheral neuropathy is striking:
- The risk of falls among older adults with DPN is 43.3% higher than those without DPN, and 2.3 times higher than people with diabetes but no neuropathy.
- People with DPN can be up to 20 times more likely to fall compared to age-matched individuals without diabetes. (Source: PMC)
- In one study of 146 people with DPN, 20% were classified as being at increased fall risk. (Source: PMC)
Why DPN Increases Fall Risk: The Mechanism
Insensate (numb) feet caused by DPN lead to a delayed neuromuscular response immediately after the foot contacts the ground during walking — a major contributing factor to increased fall risk. DPN can also cause muscle weakness, loss of ankle reflexes, and impaired balance and coordination. (Source: PMC)
The Role of Foot Drop in Diabetic Neuropathy
When peripheral neuropathy affects the peroneal nerve specifically, it can result in foot drop — compounding the fall risk already present from sensory loss with the added challenge of the foot catching or dragging during walking.
Why Balance Confidence Matters Too
Interestingly, research shows psychological factors matter as well: every one-unit increase in balance confidence was associated with a 9% reduction in the odds of falling, suggesting that fear of falling and physical risk factors interact. (Source: PMC)
Frequently Asked Questions
How much does diabetic neuropathy increase fall risk?
Research shows people with diabetic peripheral neuropathy can be up to 20 times more likely to fall than age-matched people without diabetes.
Can diabetic neuropathy cause foot drop?
Yes, when peripheral neuropathy affects the peroneal nerve, it can result in foot drop, which combines with sensory loss to further increase fall risk.
