Radial Nerve Palsy

Your wrist hangs and your fingers won't straighten, even though bending them still works. The radial nerve is usually not getting its signal through well, and treatment aims to support it while it recovers.
Radial Nerve Palsy

The Clinical Reality

Radial nerve palsy often starts suddenly. Some people wake up after sleeping on the arm, and others notice it after an injury or long pressure on the upper arm. The wrist drops, the fingers won’t open fully, and the back of the hand may feel numb.

The radial nerve runs the muscles that lift the wrist and straighten the fingers and thumb. When it is compressed or irritated, those extensor muscles get a weak or patchy signal. Grip feels weak too, because the hand can’t hold the wrist steady while the fingers close. Over weeks, the arm learns to work around the weakness, and that habit can linger.

Your doctor or neurologist confirms the diagnosis and decides on splinting, nerve testing or imaging. I work alongside that care with dry needling, a form of acupuncture, and electroacupuncture. The triceps and the supinator both sit along the radial nerve’s route, and when they’re tight they can press on it. I needle those two muscles to take that pressure off. For the nerve itself, electroacupuncture places fine needles near the radial nerve and its forearm branches with a gentle current. It is an approach grounded in neuroscience, aimed at supporting the signal to your wrist and finger extensors.

What might have been missed in standard care

Most people have been given a wrist splint and told to rest while the nerve recovers. Some have also had a nerve conduction study. Those are sensible first steps. Waiting on its own doesn’t give the nerve or the extensor muscles any added input, and the arm can settle into compensating. Physical therapy, including hand therapy, may already be part of your plan. Dry needling is something it can’t add here, since New York bars physical therapists and chiropractors from using it.

Signs & Symptoms

Do any of these sound familiar?

My wrist hangs down

Holding the wrist up against gravity is hard, and a brace that props it up makes daily tasks easier.

I can't open my hand fully

Letting go of objects and straightening the thumb are hardest, so the shoulder and elbow try to help.

My grip feels weak

Grip usually feels stronger when the wrist is held level, since the problem is lifting the wrist rather than closing the hand.

Numbness on the back of the hand

It sits near the base of the thumb and index finger, and it can shift with elbow position or upper arm pressure.

My hand tires quickly

Typing, using a mouse or holding tools turns shaky after a short time, especially late in the day.

Treatment Methods

Neuro-Functional Acupuncture

Improve nerve signaling and movement
An electroacupuncture approach grounded in neuroscience. I use targeted stimulation to influence how your nervous system is signaling, to ease nerve-related pain and help restore movement and function.

What's often behind it

The places I check first

The radial nerve itself (signaling poorly)

After compression or irritation, the nerve may carry a weak or patchy signal to the extensor muscles. Electroacupuncture is aimed here.

Triceps and supinator (muscle pressure on the nerve)

The radial nerve winds behind the upper arm beneath the triceps, then passes through the supinator in the forearm. Tight muscle at either spot can crowd it.

Extensor muscles that have gone quiet

The muscles that lift the wrist and fingers weaken without a steady signal. They can stay slow to switch on even as the nerve improves.

Neck and shoulder

The nerve's fibers start in the neck and pass the shoulder. Irritation higher up can complicate recovery further down the arm.

What happens at your first visit

What I'm checking and why

I ask how the weakness started, what testing you’ve had, and which daily tasks are hardest now. Then the exam:

  • Testing wrist, finger and thumb extension, and grip with the wrist supported and unsupported.
  • Tracing the radial nerve from the back of the upper arm into the forearm and checking sensation on the back of the hand.
  • Checking the neck and shoulder for other sources of the weakness.

I work alongside neurologists, orthopedists, hand therapists and primary care doctors. If what I find suggests checking back in with one of them, I’ll let you know and share what I found.

What to Expect

From your first visit on
First visit
The exam maps which movements are weakest, and treatment begins that same day along the radial nerve and the muscles around it.
Weeks 1 to 6
Radial nerve care usually runs twice a week for six weeks, or three times a week for four if the weakness is more severe or slow to change. I follow wrist lift, finger and thumb extension and how long you can grip or type, and I shift treatment as those improve.
After that
As wrist and finger lift hold their gains, appointments taper. How fast the radial nerve recovers depends on the injury, so this course is typical rather than promised.

Frequently Asked Questions

What people ask me before booking

Your doctor or neurologist does, usually with an exam and sometimes a nerve conduction study. They also decide on splinting, imaging and any further workup. I work alongside them and send my findings back when it helps.

It may help, and treatment is usually a combination when both the muscles and the nerve are involved. Releasing the triceps and supinator takes some pressure off the nerve’s path. Electroacupuncture aims to support the nerve’s signal to the wrist and finger muscles.

I plan in weeks rather than a set number: either two visits weekly for six weeks or three weekly for four, depending on how severe the palsy is and how it responds. A recovering nerve tends to do better with regular input to the wrist and finger extensors. When strength holds between visits, I taper. I can’t promise how fast the nerve heals.

Yes. Follow your doctor and therapist on the splint and exercises. Treatment with me is meant to sit alongside that work, and I’m glad to coordinate with your therapist.

Starting early can be helpful, since the nerve and extensor muscles get support while recovery is underway. It doesn’t guarantee a faster result. It is still worth coming in if the weakness began months ago.

Wrist and finger weakness needs a doctor’s evaluation before treatment, to rule out causes in the spinal cord, brain or elsewhere. Call 911 for sudden weakness with slurred speech, facial droop or confusion. Get seen promptly for weakness that spreads or worsens over days, severe pain after an injury, or fever.
