Peripheral neuropathy is damage to the nerves outside the brain and spinal cord, most often affecting the feet and hands in a pattern that begins at the extremities and moves inward. It causes numbness, tingling, burning pain, weakness, or a combination, and the loss of sensation matters as much as the pain: when you can't feel your feet properly, balance suffers and injuries go unnoticed. Diabetes is the most common cause, and diabetic neuropathy carries a specific risk of foot ulceration that can be limb-threatening. Physical therapy addresses balance, strength, gait, and falls prevention, and the evidence for exercise in neuropathy is better than commonly assumed.
What peripheral neuropathy is
Damage to peripheral nerves, which carry signals between the brain and spinal cord and the rest of the body.
Different nerve fibers produce different symptoms: sensory nerves cause numbness, tingling, or pain · motor nerves cause weakness · autonomic nerves affect blood pressure, digestion, and sweating.
The typical pattern is length-dependent — longest nerves affected first, so symptoms begin in the toes and feet and progress upward, with hands affected later.
Common causes
- Diabetes — the most common cause. Blood glucose management affects progression.
- Chemotherapy — several agents cause neuropathy, sometimes persisting after treatment ends.
- Alcohol-related, B12 deficiency — which is treatable and worth testing for — autoimmune and inflammatory conditions, inherited neuropathies, kidney disease, and some medications.
- Idiopathic — no cause identified after investigation, which is common and frustrating.
Investigating the cause matters because some are treatable and some change management substantially.
Why balance is affected
Your balance depends on three systems — vision, the vestibular system in the inner ear, and sensation from your feet and joints telling you where you are.
Neuropathy degrades the third. You lose the continuous information stream that tells you how your foot is contacting the ground.
What helps with peripheral neuropathy
- Balance training — specifically targeted, progressive, and continued. The other systems can partly compensate for lost sensation, but only if trained to. → Balance retraining
- Strength, particularly in the legs and around the ankles.
- Gait work — neuropathy changes how people walk, often toward a wider, more cautious pattern that is itself less stable.
- Footwear review — supportive, well-fitting shoes that protect insensate feet.
- Home hazard assessment — lighting matters more than usual, given the reliance on vision.
- Exercise generally. The evidence for exercise in peripheral neuropathy is better than commonly assumed — including for balance, strength, and in some studies symptoms themselves. It's frequently not offered.
- Assistive devices where appropriate — a stick or poles are not a failure, and they meaningfully reduce falls risk.
Pain management, discussed with your doctor. Neuropathic pain often responds to different medications than other pain, and this is a medical rather than a rehabilitation question.
Goals worth setting
Get to the bathroom at night without holding the walls · Walk on grass without fear · Stand at the kitchen counter for ten minutes · Go up and down stairs confidently
Improve balance · Increase ankle strength

Frequently Asked Questions
Will the numbness go away?
It depends on the cause. Some neuropathies improve when the underlying cause is treated — B12 deficiency, for instance. Others are persistent, and management focuses on function and safety.
Should I use a walking stick?
If it reduces your falls risk, yes. Using one isn't a failure — falls have serious consequences, and a device that prevents them is doing its job.
Is my neuropathy from diabetes?
Diabetes is the most common cause, but others include chemotherapy, alcohol, B12 deficiency, and autoimmune conditions — and some cases have no identified cause. Investigation matters because some are treatable.
Why is my balance worse in the dark?
Balance uses vision, the inner ear, and sensation from your feet. Neuropathy degrades the third, so you rely more on vision — and lose that compensation when the lights go down.
Can exercise help peripheral neuropathy?
Yes, and it's frequently not offered. Exercise has evidence for balance, strength, and in some studies for symptoms. Balance training in particular helps the other systems compensate for reduced sensation.
Why do I need to check my feet every day?
Because reduced sensation means injuries go unnoticed. A blister or small cut can become a serious wound before you feel it, and in diabetes that carries a risk of ulceration.
What shoes are best for peripheral neuropathy?
Supportive, well-fitting shoes that protect insensate feet. A footwear review is part of what therapy covers, alongside a home hazard assessment — lighting matters more than usual here, given how much you are relying on vision to compensate.
Why doesn't ordinary pain medication help my neuropathy pain?
Neuropathic pain often responds to different medications than other pain. That is a medical rather than a rehabilitation question, and one to discuss with your doctor.
