You wake up in the middle of the night because your hand feels numb.

You shake it.

Change positions.

Maybe hang your hand over the edge of the bed.

Eventually, it feels better.

Then during the day, you notice something similar while holding your phone, typing, driving, or using a mouse.

The natural conclusion is:

“I must have carpal tunnel.”

Maybe—but hand numbness is not automatically carpal tunnel syndrome.

Where the symptoms occur, which fingers are involved, whether neck or arm positions affect them, whether weakness is present, what happens at night, and what the physical examination shows can all matter.

This makes hand numbness a particularly good example of why a physical therapy evaluation should be more than:

“Where does it hurt?”

Patient Question

“My hand keeps going numb at night, and sometimes it happens when I'm holding my phone or working at my computer. I have to shake my hand to make it feel better. Is this carpal tunnel syndrome, and can physical therapy help?”

The Short Answer

Possibly—but symptoms alone should not be used to make that conclusion.

Carpal tunnel syndrome involves compression of the median nerve at the wrist. Symptoms can include numbness, tingling, altered sensation, discomfort and, in some cases, motor or functional changes.

But similar complaints can potentially arise from other locations or conditions.

That is why:

hand numbness ≠ automatically carpal tunnel syndrome.

The newly revised 2026 APTA/JOSPT Carpal Tunnel Syndrome Clinical Practice Guideline recommends combining the symptom history with appropriate examination measures rather than relying on one symptom or one test. DOI

For appropriate mild-to-moderate presentations managed nonsurgically, the guideline supports interventions including education about aggravating activities, ergonomic strategies and a correctly fitted neutral-position wrist orthosis worn at night. DOI

Key Takeaways

1. Hand numbness does not automatically mean carpal tunnel syndrome.

The pattern and examination matter.

2. Which fingers become numb is useful information.

Symptom distribution can help guide the examination, but it should not be used alone to establish a diagnosis.

3. Nighttime symptoms are common in carpal-tunnel-type presentations.

The 2026 guideline specifically recommends a neutral-position nighttime wrist orthosis for short- and/or mid-term improvement in symptoms and function for appropriate mild-to-moderate CTS presentations. DOI

4. Your computer setup may matter—but “perfect posture” isn't the entire answer.

The updated guideline specifically addresses mouse use, keyboard demands and alternative strategies. DOI

5. Progressive weakness deserves more attention than occasional tingling alone.

Changes in thumb muscle performance, dexterity or persistent sensation should be appropriately evaluated.

Why Does My Hand Go Numb at Night?

This is one of the most interesting aspects of carpal-tunnel-type symptoms.

During sleep, people can remain in the same position for long periods.

The wrist may also spend substantial time bent rather than near neutral.

For someone with a sensitive median nerve at the wrist, certain prolonged positions may contribute to symptoms.

That's why the story sometimes sounds like:

Go to sleep → wake up with tingling → shake the hand → symptoms settle → go back to sleep.

But here's the important Nova distinction:

Nighttime hand numbness is a clue—not a diagnosis.

A physical therapist should still consider the overall symptom pattern and examination.

Why Do I Shake My Hand When It Goes Numb?

Patients sometimes describe this without realizing how common the behavior is:

“I wake up and automatically shake my hand.”

They may feel that shaking or changing position temporarily reduces the tingling.

That tells us something about symptom behavior.

It doesn't tell us, by itself, exactly why the symptoms occurred.

A good evaluation asks what happened immediately before the numbness and what positions or activities make it better or worse.

Which Fingers Usually Matter?

This is where the anatomy becomes useful.

The median nerve supplies sensation to characteristic regions of the hand.

But real patients don't always arrive with textbook-perfect symptom maps.

Someone may say:

“My whole hand falls asleep.”

Another:

“Mostly my thumb and first two fingers.”

Another:

“I can't really tell—it's just tingling.”

Rather than forcing the patient's symptoms into a diagnosis, the clinician can map the symptoms and combine that information with the rest of the examination.

The 2026 CPG recommends the Katz and Stirrat hand symptom diagram to help determine the location and nature of symptoms in suspected CTS. DOI

Why Does Holding My Phone Make My Hand Numb?

Think about what happens when you scroll for 30 minutes.

You may be:

gripping the phone

while

holding the wrist in one position

while

repeatedly moving the thumb

while

keeping the elbow bent

and perhaps

looking downward with the neck flexed.

The useful clinical question isn't simply:

“Are phones bad for your hands?”

They aren't inherently.

A better question is:

“Does this particular position or duration consistently reproduce your symptoms?”

If symptoms begin after two minutes, that's different from symptoms beginning after an hour.

That gives the therapist information about the patient's current tolerance.

Why Does My Hand Go Numb While Driving?

Driving can create another prolonged-position problem.

The hands may remain on the steering wheel for an extended period while the elbows, shoulders and wrists remain relatively static.

A patient may report:

“Ten minutes is fine, but during my commute my fingers start tingling.”

Again, the time to symptom onset becomes useful information.

For a North Hollywood or Los Angeles patient who spends substantial time commuting, simply saying:

“Avoid driving.”

isn't realistic rehabilitation.

A better goal is understanding the presentation and improving the patient's ability to function during the activities their life actually requires.

Is My Computer Causing Carpal Tunnel Syndrome?

This question deserves a more nuanced answer than:

“Typing causes carpal tunnel.”

The relationship between work exposure and symptoms is more complex.

But ergonomics can still matter when certain positions or tasks repeatedly provoke symptoms.

The new 2026 guideline specifically states that clinicians may educate patients about mouse use and carpal tunnel pressure and help develop alternative strategies such as:

• Alternating the mouse hand
• Using arrow keys
• Using touch screens
• Modifying relevant hand/wrist positions

For people who experience pain with keyboard use, keyboards requiring less key-strike force may also be considered. DOI

That's very different from telling everyone:

“Buy an ergonomic keyboard and your carpal tunnel will disappear.”

Is There a Perfect Wrist Position?

Not necessarily for every activity.

But for nighttime orthosis use in mild-to-moderate CTS, the 2026 guideline is much more specific.

It recommends a forearm-based wrist immobilization orthosis that maintains the wrist near neutral, worn at night for short- and/or mid-term improvement in symptoms and function. DOI

This is important because people sometimes buy a random wrist brace online and assume:

brace = correct treatment.

The position and fit matter.

PT Insight

A wrist brace is not useful simply because it says “carpal tunnel” on the package. The updated clinical guideline specifically emphasizes a properly fitted orthosis that maintains the wrist near neutral. DOI

Should I Wear My Wrist Brace All Day?

Not automatically.

For appropriate mild-to-moderate CTS, the guideline emphasizes nighttime use initially.

If night-only use does not adequately control symptoms, clinicians may consider adjusting wear time to symptomatic periods, daytime use or other schedules depending on the individual presentation. DOI

That is why:

“Wear this brace 24/7”

isn't a universal recommendation.

What If My Hand Numbness Is Coming From My Neck?

This is one reason a good upper-extremity evaluation shouldn't automatically stop at the wrist.

Some neurological symptoms in the upper extremity can potentially relate to structures elsewhere along the pathway.

Depending on the presentation, a physical therapist may assess:

neck movement

upper-extremity movement

sensation

muscle performance

neural mobility

and

symptom response to different positions.

The purpose isn't to diagnose a disease from a symptom.

It's to determine whether the presentation is appropriate for physical therapy and whether findings indicate that additional medical assessment is needed.

What Are Phalen's, Tinel's and Durkan's Tests?

These names frequently appear when people search for carpal tunnel tests online.

The 2026 CPG recommends using:

Phalen test

Tinel sign

and

carpal compression/Durkan test

to help evaluate people with suspected CTS. DOI

But this is where internet self-testing becomes problematic.

One positive test does not equal a diagnosis.

The guideline explicitly notes that the evidence does not support using an isolated provocative test to confirm CTS. DOI

That is an extremely important distinction.

What Does a Physical Therapist Check Besides Pain?

Quite a lot.

The updated guideline includes examination recommendations involving:

symptom distribution

sensory testing

motor function

hand function

thenar muscle appearance

grip and pinch performance when appropriate

and combinations of clinical findings. DOI

The guideline recommends Semmes-Weinstein monofilaments for sensory threshold and static two-point discrimination for sensory innervation density. It also allows assessment of grip/pinch performance, dexterity and the thenar muscles when appropriate. DOI

That means an evaluation can move beyond:

“Does this test hurt?”

toward:

“How is sensation and function actually being affected?”

What Is the CTS-6?

This is another useful example of modern clinical reasoning.

Rather than relying on one symptom or one provocative test, clinicians can combine findings.

The 2026 CPG recommends the Carpal Tunnel Syndrome-6 (CTS-6) to help evaluate people with suspected CTS. DOI

The broader lesson for patients is important:

good clinical reasoning combines information.

It doesn't hang an entire conclusion on one symptom.

What if I'm Starting to Drop Things?

This deserves more attention.

Occasional clumsiness can happen for many reasons.

But if you are noticing a new or progressive decline in hand function, such as increasing difficulty with:

buttons

keys

gripping objects

fine motor tasks

or repeated dropping of objects, it should be appropriately evaluated.

The same applies if there is visible loss of muscle bulk around the thumb or progressive weakness.

Those findings may affect the urgency and type of evaluation needed.

What About Carpal Tunnel During Pregnancy?

Carpal-tunnel-type symptoms can occur during pregnancy.

The 2026 guideline specifically states that clinicians may recommend an orthosis for women experiencing CTS during pregnancy and recommends a postpartum follow-up evaluation to assess whether symptoms have resolved. DOI

Again, treatment should be individualized and coordinated with the patient's appropriate healthcare providers when needed.

Are Nerve-Gliding Exercises the Answer?

This is where we need to resist another internet simplification.

Search online and you'll find:

“Three nerve glides to cure carpal tunnel.”

But evidence-based rehabilitation is not that simple.

The updated guideline does not suggest that one nerve exercise should automatically be prescribed to everyone with hand numbness.

Exercise selection should follow the examination and should be appropriate for the individual's presentation.

What About Stretching?

The 2026 guideline states that clinicians may use a combined orthotic/stretching program in appropriately selected people with nonsurgically managed mild-to-moderate CTS who do not have thenar atrophy and have normal two-point discrimination. DOI

Notice how specific that recommendation is.

It isn't:

“Everyone with numb fingers should stretch their wrist.”

That specificity is exactly why evaluation matters.

What About Manual Therapy?

For nonsurgically managed mild-to-moderate CTS, the updated guideline states that clinicians may perform manual therapy directed at the cervical spine and upper extremity in areas of median nerve entrapment for short-term improvement in pain and function. DOI

The key words are:

may

and

short-term.

Manual therapy should not be portrayed as mechanically “freeing a trapped nerve” or permanently correcting the underlying problem.

It is a potential component of care—not a guaranteed cure.

Can Physical Therapy Help?

For appropriate mild-to-moderate CTS presentations, yes, physical therapy may be part of nonsurgical management.

In fact, the 2026 APTA/JOSPT guideline concludes that physical therapy intervention is indicated as initial management for confirmed or suspected mild-to-moderate CTS and emphasizes:

education + modification of aggravating activities/risk factors + appropriately fitted neutral-position nighttime wrist orthosis. DOI

Depending on the individual evaluation, PT may address:

• Activity modification
• Ergonomic strategies
• Wrist positioning
• Orthosis education
• Upper-extremity movement
• Appropriate stretching/exercise
• Functional limitations
• Work tolerance
• Hand use
• Relevant cervical and upper-extremity findings
• Patient education

And equally important:

physical therapy should recognize when the presentation requires additional medical evaluation rather than simply continuing conservative care indefinitely.

What Patients Often Assume vs. What Current Evidence Says

What Does Research Say?

2026 APTA/JOSPT Clinical Practice Guideline

This is what makes today's article particularly timely.

In February 2026, APTA published the revised Hand Pain and Sensory Deficits: Carpal Tunnel Syndrome Clinical Practice Guideline, developed by APTA Orthopedics and APTA Hand and Upper Extremity. The complete guideline appeared in the April 2026 issue of JOSPT. APTA

It contains updated recommendations covering:

examination → diagnostic testing → outcome measures → orthoses → ergonomics → manual therapy → exercise → nonsurgical rehabilitation.

One of the most practical recommendations is the use of a properly fitted neutral-position nighttime wrist orthosis for appropriate mild-to-moderate CTS presentations. DOI

September 2026 Evidence Update

This month, JOSPT published an additional article specifically translating the 2026 evidence into musculoskeletal rehabilitation practice.

The authors highlight three particularly practical elements:

neutral-position wrist orthosis + activity modification + ergonomic/risk-factor strategies. PubMed

That makes this one of the freshest evidence-based topics we can publish on Nova's website right now.

AAOS/ASSH Clinical Practice Guideline

The American Academy of Orthopaedic Surgeons and American Society for Surgery of the Hand also published an evidence-based CTS guideline based on systematic review of the literature, with a guideline summary appearing in 2025. PubMed

What Does This Mean for Patients?

The modern approach is not:

“Your fingers tingle, so buy a brace.”

And it isn't:

“One positive wrist test proves carpal tunnel.”

A better sequence is:

understand the symptom pattern → evaluate sensation and function → use appropriate combinations of tests → identify aggravating activities → select evidence-supported conservative management when appropriate → monitor progress → refer when findings warrant additional medical care.

What Happens During a Physical Therapy Evaluation?

At Nova Physical Therapy, an evaluation for hand numbness or tingling may include, when appropriate:

• Detailed symptom history
• Mapping where symptoms occur
• Hand and wrist movement
• Relevant neck and upper-extremity movement
• Sensory testing
• Muscle-performance testing
• Hand function
• Grip or pinch performance when relevant
• Functional dexterity when appropriate
• Provocative testing
• Workstation/activity discussion
• Sleep-position discussion
• Functional tasks
• Screening for findings requiring referral

We may ask:

Which fingers become numb?

Does it wake you at night?

Do you shake your hand for relief?

Does holding your phone reproduce it?

Does driving reproduce it?

What happens when you type or use a mouse?

Does changing your neck position affect it?

Are you dropping objects?

Has your grip changed?

Is the numbness intermittent or constant?

What activities are becoming difficult?

Those details create a clinical story.

The examination then helps determine whether the presentation is appropriate for physical therapy or whether additional medical assessment is indicated.

California law maintains a prohibition on physical therapists diagnosing disease, so Nova's content and care should distinguish physical therapy examination and management of movement/function from medical diagnosis. Physical Therapy Board of California

When Should You Seek Medical Attention?

Hand tingling that occasionally appears in one position is very different from rapidly progressive neurological loss.

Seek appropriate medical evaluation for symptoms such as:

• Sudden numbness associated with other acute neurological symptoms
• Progressive or significant weakness
• Increasing loss of hand function
• Persistent or worsening loss of sensation
• Visible progressive muscle wasting
• Significant trauma
• Severe swelling or deformity
• Signs of infection
• New neurological symptoms involving larger portions of the arm or body
• Other rapidly worsening or concerning symptoms

Call emergency services for sudden one-sided weakness or numbness associated with facial drooping, speech difficulty, severe sudden neurological symptoms, chest pain, or another potential emergency.

Persistent symptoms that are not progressing as expected should also be appropriately reassessed.

Why Patients Choose Nova Physical Therapy

At Nova Physical Therapy, our philosophy is simple:

We Care.

But consider what hand numbness actually means to different people.

For one person:

“I wake up three times every night because my hand falls asleep.”

For another:

“I can't get through my commute without shaking my hand.”

For someone else:

“I'm a hairstylist, and my hand symptoms start halfway through my workday.”

Or:

“I'm at a computer eight hours a day and I'm starting to worry because my fingers keep tingling.”

Those are not simply four versions of:

“carpal tunnel.”

They're four different functional problems.

So our first question shouldn't simply be:

“Where does it hurt?”

We also want to understand:

What activity brings the symptoms on?

How quickly do they appear?

Which fingers are involved?

What makes them change?

Is sensation or muscle performance affected?

What does the physical therapy examination show?

What do you need your hand to do every day?

Then treatment can be built around the actual person.

Our approach emphasizes:

• Individualized physical therapy evaluation
• Evidence-informed care
• Functional assessment
• Patient education
• Appropriate ergonomic strategies
• Activity modification when indicated
• Evidence-supported orthosis education when appropriate
• Progressive rehabilitation
• Monitoring of neurological and functional findings
• Appropriate referral when additional medical assessment is indicated

The goal isn't to give everyone with tingling the same wrist exercise.

The goal is to understand what is limiting your function and determine the appropriate path forward.

That's part of what We Care means to us.

Frequently Asked Questions

Why does my hand go numb while I sleep?

Prolonged wrist and upper-extremity positioning can contribute to symptoms in some people. Nighttime symptoms can occur with CTS, but night numbness alone does not establish a diagnosis.

Why do I have to shake my hand at night?

Some people find that movement or changing position temporarily changes their symptoms. This behavior can be useful information during an evaluation.

Does numbness in my thumb and fingers mean carpal tunnel?

It may be consistent with a median-nerve distribution, but symptom location alone does not establish CTS.

Can using my phone cause hand numbness?

Prolonged gripping and positioning may provoke symptoms in some people. The important question is whether specific positions or durations consistently reproduce your symptoms.

Can computer work cause carpal tunnel?

The relationship is more complicated than simply “typing causes CTS.” The 2026 guideline nevertheless supports addressing relevant mouse use, wrist/hand positions and aggravating activities. DOI

Should I wear a wrist brace at night?

For appropriate mild-to-moderate CTS presentations, the 2026 guideline recommends a correctly fitted forearm-based wrist orthosis maintaining the wrist near neutral at night. DOI

Does a positive Phalen's test mean I have carpal tunnel?

Not by itself. The guideline specifically notes that an isolated provocative test should not be used to confirm CTS. DOI

Can hand numbness come from somewhere other than my wrist?

Yes. Several presentations can produce hand sensory symptoms, which is why the history and broader examination matter.

Are nerve glides enough to treat carpal tunnel?

There is no universal exercise that should automatically be prescribed to every person with hand numbness.

Can physical therapy help carpal tunnel syndrome?

For appropriately selected mild-to-moderate CTS presentations, the 2026 APTA/JOSPT guideline supports physical therapy as an initial nonsurgical management approach. DOI
