Equipment for Post-Stroke Recovery

Rewiring, not regrowth

• A stroke injures the brain, not the nerves in your arm and leg. Those nerves are usually perfectly intact. What's damaged is the control center sending them instructions. That's why an arm can test strong one moment and be unusable for a task the next. The wiring works. The signal doesn't.
• Brain tissue doesn't regenerate the way a nerve in your leg does. A compressed nerve in the low back regrows at about a millimeter a day. The brain has nothing equivalent. Recovery comes from neuroplasticity instead, meaning surviving parts of the brain take over work the damaged area used to do, and quiet connections get recruited and strengthened.
• That changes what actually drives your recovery. With a regrowing nerve, time does most of the work and you mostly wait. With neuroplasticity, what you practice is what rewires. Repetition, difficulty, and whether the task means something to you all shape the result. It's why stroke rehab asks so much more of you than rehab after surgery does, and why the number of repetitions matters as much as the exercise.
• Recovery moves shoulder to hand, and hip to foot. Control at the shoulder and hip usually returns before the elbow and knee, which return before the hand and foot. Fine hand control is typically slowest and least complete. Seeing the shoulder come back while the hand sits still is the normal order, not a sign the hand won't follow.
• Sensation often lags movement, and it matters more than people expect. A limb that moves but can't feel is much harder to use, because your brain relies on feedback to control it without watching. Reduced sensation also raises the risk of burns, pressure injuries, and skin breakdown you won't notice happening. That's why positioning and skin checks stay important even as strength improves.
• Muscle tone changes over the first weeks and months. A limb that starts out floppy often develops increasing tone and spasticity. That shift is part of the process, not a setback, but it does change what equipment fits. A brace or splint sized while the arm was flaccid usually needs rechecking once tone shows up.

The exception, when a nerve is involved too

Sometimes a stroke comes with a genuine nerve injury on top of it, and that one does follow the slow regrowth clock. The usual cause is the weak shoulder itself. When the muscles holding the joint together go flaccid, the weight of the arm can pull it partly out of position and stretch the nerves crossing it. Prolonged pressure on a limb that can't feel or shift itself does the same thing.

Where that happens, you're back to nerve rules: about a millimeter a day, roughly an inch a month, working outward from the injury. It's also largely preventable, which is the practical point. Supporting that arm, not pulling on it during transfers, and repositioning regularly aren't comfort measures. Never lift or pull someone by the weak arm.

• A physician's order is required. Medicare only covers durable medical equipment (DME) — items that are reusable, primarily and customarily used for a medical purpose, and appropriate for use in the home — when a physician or treating practitioner documents it as medically necessary, and it's supplied by a Medicare-enrolled DME supplier that accepts assignment.
• Cost share: Once the annual Part B deductible ($283 in 2026) is met, Medicare pays 80% of the Medicare-approved amount; the patient (or a supplemental/Medigap plan) is responsible for the remaining 20% coinsurance.
• Rental vs. purchase: Standard wheelchairs and similar "capped rental" items are typically rented rather than purchased outright — Medicare pays the monthly rental for up to 13 continuous months, after which ownership automatically transfers to the patient. Simpler items, like canes and walkers, are usually purchased outright from the start.
• Replacement — the 5-year rule: Most DME has a Medicare-defined "reasonable useful lifetime" of 5 years from the delivery date. Medicare will cover a replacement once that period has passed, if the item is still medically necessary. Within the 5 years, Medicare generally covers repairs for normal wear rather than a full replacement.
• Early replacement exceptions: equipment that's lost, stolen, or damaged beyond repair (a fall, fire, accident) can usually be replaced before the 5 years are up with documentation, such as a police or insurance report — as can equipment that no longer meets a patient's needs because of a genuine change in their medical condition.

Not everything on this page is DME. Many items below — adaptive daily-living aids, over-the-counter comfort products, and similar convenience items — fall outside Medicare's DME definition and are typically not covered, regardless of the rules above. This is general education, not a coverage determination for any specific item; confirm coverage for a specific piece of equipment with a physician, a DME supplier, or Medicare directly.
