Hand & Wrist Conditions

Carpal Tunnel Syndrome

More Than Just "Wrist Pain"

That numb, tingling hand at night is your nerve telling you something is wrong. Finding out what is driving the compression — and addressing it properly — is the only way to recover for good.

Carpal Tunnel Syndrome (CTS) is the most common peripheral nerve compression condition — yet it is frequently misunderstood and poorly managed. At Alleviate Physiotherapy, we treat CTS by identifying the underlying causes of nerve compression, not just relieving symptoms temporarily. The right treatment, applied in the right sequence, is what separates lasting recovery from a cycle of recurring flare-ups.

What is Carpal Tunnel Syndrome?

The carpal tunnel is a rigid, narrow closed compartment in your wrist — formed by the carpal bones below and the transverse carpal ligament above. Running through this small space is the median nerve, which supplies sensation to the thumb, index finger, middle finger, and half of the ring finger, and controls key muscles at the base of the thumb.

When pressure inside this tunnel rises, the median nerve becomes compressed. The result is the characteristic numbness, tingling, and weakness of CTS. The compression itself is the symptom — the question a thorough clinical assessment must answer is why the pressure increased in the first place.

CTS is a Symptom, Not a Standalone Diagnosis

Nerve compression in the carpal tunnel is almost always the result of identifiable contributing factors — repetitive loading patterns, postural habits, systemic conditions, or structural changes at the wrist. A proper physiotherapy assessment uncovers those factors. Without that, treatment addresses the compression without resolving what caused it — and symptoms return.

What Happens Inside the Tunnel?

The carpal tunnel has fixed walls — bone on three sides and a tight ligament on top. It cannot expand. When anything increases the volume of its contents — inflammation, fluid retention, repetitive tissue stress, or structural changes — pressure rises and the median nerve bears the consequences.

The nerve does not simply "get pinched." Sustained compression first disrupts blood flow to the nerve, then impairs nerve signal conduction, and eventually — if left unmanaged — leads to permanent structural damage. By the time weakness and muscle wasting appear at the base of the thumb, the nerve has already sustained significant injury. This progression is exactly why early assessment matters.

Why Did CTS Develop?

The cause is not always obvious — and that is precisely why self-diagnosing and self-managing CTS is unreliable. A physiotherapist's assessment identifies the specific contributors driving your nerve compression. Common factors include:

Repetitive Strain & Loading

Frequent, forceful gripping, sustained wrist flexion, or using vibrating power tools increases pressure within the tunnel with each repetition. Over time, this cumulative load inflames the tendons sharing the tunnel with the nerve — reducing available space and compressing the median nerve.

Postural & Ergonomic Factors

Prolonged keyboard use with wrists dropped or hyperextended, poor mouse positioning, and sustained wrist deviation all raise carpal tunnel pressure. These are modifiable — but modification requires an assessment of your specific patterns, not generic advice from a website.

Fluid & Systemic Changes

Pregnancy, hypothyroidism, diabetes, and rheumatoid arthritis can all alter fluid dynamics or tissue composition in ways that raise tunnel pressure. Pregnancy-related CTS often resolves after delivery — but other systemic contributors require coordinated management with your medical team.

Sleep Position & Night Symptoms

Sleeping with wrists flexed or tucked under a pillow dramatically increases carpal tunnel pressure — which is why nighttime tingling and hand numbness are so characteristic of CTS. Addressing sleep position is part of the treatment plan, not an afterthought.

Signs You Shouldn't Ignore

CTS symptoms develop gradually — which is exactly why people dismiss them until the condition is well established. Any of the following warrants a physiotherapy assessment rather than continued waiting:

Nighttime Tingling or Numbness: Waking with a numb, "asleep" hand — typically affecting the thumb, index, and middle fingers. A hallmark sign of CTS.
Activity-Triggered Symptoms: Tingling or pain during driving, holding a phone, typing, or gripping a cup. These are not normal. They signal an irritated nerve.
Temporary Relief from Shaking the Hand: Vigorously shaking or massaging the hand eases symptoms temporarily — a distinctive feature of median nerve compression.
Weakness When Gripping or Pinching: Difficulty opening jars, doing up buttons, or holding small objects — signs the motor fibres of the nerve are affected.
Thumb Muscle Wasting: Visible thinning of the muscle at the base of the thumb (thenar atrophy) signals advanced nerve damage requiring prompt assessment.
Symptoms in Both Hands: Bilateral CTS is common and often points to a systemic contributing factor that needs identifying and addressing.

Why a Proper Assessment Matters

Many people spend weeks pressing on their wrists, comparing symptoms to online descriptions, and trying exercises from videos. The problem is that nerve compression presents differently from person to person — and several other conditions closely mimic CTS.

Cervical radiculopathy, thoracic outlet syndrome, pronator teres syndrome, and cubital tunnel syndrome can all produce hand tingling and numbness. Starting CTS treatment when the actual source of compression is elsewhere will not help — and delays recovery by months. A physiotherapist uses hands-on clinical testing and movement analysis to identify exactly what is happening and where before any treatment begins.

How Can Physiotherapy Help with CTS?

The most important thing to understand about CTS management: it is not simply about what to do — it is about how each intervention is applied and in what sequence. Splinting before nerve mobilisation makes sense. Loading exercises before nerve irritability settles does not. A physiotherapist determines that sequence for you — based on your specific presentation, not a standard protocol.

At Alleviate Physiotherapy, we follow our signature three-step approach:

Assess

A thorough clinical examination to identify the source and severity of nerve compression, the contributing factors, and any conditions that mimic or co-exist with CTS.

Alleviate

Targeted hands-on treatment, postural correction, load modification, and splinting — applied in the right order to reduce nerve irritability and create the conditions for recovery.

Achieve

A progressive return to full hand function — with contributing factors addressed so nerve compression does not simply recur when activity resumes.

Treatment Approaches — Guided by Your Therapist

The following are evidence-based tools your physiotherapist may draw from. Which ones apply, in what combination, and at what stage is a clinical decision — based on your assessment findings, nerve irritability, and how you respond to each intervention week by week.

Step 1: Reducing Nerve Compression and Irritability

Wrist Splinting

A neutral-position wrist splint — worn primarily at night — reduces carpal tunnel pressure during sleep and gives the nerve uninterrupted recovery time. Your therapist fits and advises on the splint, including when daytime use is appropriate and when it is not. Wearing a splint indefinitely without addressing the underlying cause simply delays the problem.

Activity & Ergonomic Modification

Your therapist assesses the specific tasks, postures, and loading patterns contributing to your symptoms. Recommendations are individualised — not generic. Adjusting your workstation, modifying grip patterns, and restructuring repetitive tasks significantly reduces ongoing nerve irritation. The goal is to remove the stimulus driving the compression, not simply limit all activity.

Neural Mobilisation (Nerve Gliding)

Graduated nerve mobilisation techniques improve the median nerve's ability to move freely through the carpal tunnel and along its entire pathway. These are introduced carefully — at the right stage and with the right technique for your presentation. Aggressive nerve gliding in an acutely irritated nerve worsens symptoms. Your therapist determines the appropriate approach, intensity, and timing.

Step 2: Restoring Function and Strength

Tendon Gliding & Hand Mobility Exercises

Specific sequences of finger and wrist movements help the tendons within the carpal tunnel move more freely, reducing adhesion and improving tissue mobility around the nerve. The sequence of these exercises matters — your therapist prescribes them in the correct order and adjusts them as your presentation evolves. Following a generic exercise video misses this entirely.

Grip Strength & Thenar Rehabilitation

Once nerve irritability settles, progressive strengthening of the grip and intrinsic hand muscles — particularly the thenar group at the base of the thumb — restores functional capacity. Starting strengthening before the nerve has adequate recovery aggravates symptoms. Your therapist determines when loading is appropriate.

Postural & Cervical Assessment

Nerve compression does not always originate at the wrist alone. Restricted cervical mobility, thoracic outlet tightness, or double crush phenomena — where the nerve is compressed at more than one point — can contribute to or mimic CTS. Your physiotherapist screens for these as part of a comprehensive assessment and addresses contributing factors throughout the kinetic chain.

Step 3: Medical and Surgical Pathways (When Needed)

Cortisone Injection — A Considered Option, Not a Fix

A corticosteroid injection can provide meaningful short-term relief — with approximately 80% of patients experiencing symptom reduction. However, symptoms return in most patients within 2 to 4 months if contributing factors go unaddressed. Your physiotherapist works with your GP or specialist to determine whether an injection is appropriate, and ensures a structured rehabilitation programme follows to address the underlying drivers.

Carpal Tunnel Release Surgery

Open carpal tunnel release — dividing the transverse carpal ligament to expand the tunnel — is appropriate when conservative management fails after an adequate trial, or when there is objective evidence of nerve damage such as muscle wasting or abnormal nerve conduction findings. Open release carries a lower complication rate than endoscopic techniques. Surgery relieves the structural compression — physiotherapy rehabilitation is essential to restore full function afterwards.

Post-Surgical Rehabilitation: Sequence Matters

Recovery after carpal tunnel release follows a predictable progression — but how quickly and safely you move through each stage depends on your tissue's response, not a calendar. Your physiotherapist tracks that response and adjusts the programme accordingly.

Days 0–7

Gentle wrist and full finger range-of-motion exercises begin immediately. Early movement reduces stiffness and swelling. Your therapist guides appropriate intensity — too vigorous in the first days increases scar tissue formation.

Week 2

Sutures are removed. More formal range-of-motion work begins, along with gradual nerve mobilisation exercises as nerve sensitivity allows. Your therapist assesses wound healing and tissue response before progressing.

Weeks 2–4

Most patients return to light work as pain permits. A padded glove protects the scar during tasks involving grip or pressure over the palm. Return-to-work timing is a clinical decision — based on your job demands and your tissue's actual recovery, not a standard timeframe.

Weeks 4–8

Progressive grip strengthening and thenar rehabilitation begin. Scar management — including deep massage and silicone gel sheeting — softens the scar, reduces sensitivity, and improves tissue mobility around the nerve. Your therapist introduces each element at the appropriate stage.

Months 2–3+

Full return to occupational and recreational demands, with the ergonomic and movement contributors from the original assessment fully addressed. Without this final step, the factors that created the problem remain — and symptoms can recur even after surgery.

⚠ Self-Testing Is Not a Substitute for Clinical Assessment

The Phalen manoeuvre, Tinel sign, and direct compression tests are useful screening tools in trained hands — but they have limited reliability when self-administered. A positive result at home tells you symptoms are present. It does not tell you whether the source is the carpal tunnel, the cervical spine, the thoracic outlet, or a combination of all three. Only a full clinical assessment can answer that — and the answer determines the treatment.

When Should You See a Physiotherapist?

Sooner than most people think. CTS is frequently dismissed as something that will "settle down" with rest or a wrist brace from the pharmacy. But without identifying and addressing the contributing factors, symptoms return as soon as activity resumes — and the nerve continues to accumulate damage in the meantime.

Book an assessment promptly if any of the following apply:

Nighttime hand tingling or numbness has occurred more than a handful of times.
Symptoms occur during everyday tasks like driving, typing, or holding a phone.
You have noticed weakness, clumsiness, or difficulty with fine motor tasks in your hand.
Symptoms affect both hands — bilateral CTS often points to a systemic contributing factor.
You have tried a wrist splint and symptoms improved — but return when you stop wearing it.
A doctor has told you that you have CTS, but you have not yet had a physiotherapy assessment of the underlying contributors.

🚨 Visible Thumb Muscle Wasting Requires Prompt Medical Assessment

If you notice visible thinning or weakness of the muscle at the base of your thumb (thenar atrophy), the median nerve has already sustained significant damage. Do not delay seeking assessment. This is a sign of advanced CTS that may require urgent nerve conduction testing and surgical consultation — the window for full nerve recovery narrows with time.

CTS That Has Been "Just Splinted" for Months Is Not Being Managed

A wrist splint reduces symptoms — it does not resolve the underlying cause. Without identifying the specific loading patterns, postural habits, or systemic factors driving the nerve compression, removing the splint restarts the cycle. The longer those contributing factors persist, the more cumulative damage the nerve sustains and the harder full recovery becomes. If CTS has been limiting you without a clear treatment plan addressing the root cause, now is the time to change that.

Your Nerve Is Telling You Something — Find Out What

CTS does not resolve through generic splinting or exercises found online. Our physiotherapists will assess your hand and wrist thoroughly, identify exactly what is driving the nerve compression, and build a treatment plan around your recovery — delivered in the right sequence, not a standard protocol.
