Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) is the most common nerve-entrapment disorder of the upper limb. It happens when the median nerve – the cable that carries feeling and muscle power to the thumb, index, middle and part of the ring finger – gets squeezed inside the wrist’s “carpal tunnel.” That tunnel is a rigid, narrow passageway made of eight wrist bones and a tough roof-ligament; anything that narrows the tunnel or swells its contents raises the pressure. When pressure climbs high enough, the nerve’s blood supply falters, its insulating myelin frays, and the electrical messages that let you feel and move no longer travel smoothly. The earliest complaint is often night-time tingling; untreated, CTS can progress to constant pain, loss of grip, and visible wasting of the thumb-base muscles. Modern guidelines rate CTS-6 clinical scoring, nerve-conduction testing and ultrasound as the most accurate diagnostic tools when symptoms are unclear. aaos.orgaaos.org

Carpal Tunnel Syndrome happens when the median nerve—your thumb-side “phone–scrolling” nerve—gets squeezed inside a narrow passage in the wrist called the carpal tunnel. That tunnel is a hard U-shaped arch of wrist bones topped by a tough roof (the transverse carpal ligament). Repetitive bending, vibration, swelling inside the tunnel or even fluid shifts during pregnancy can make the space too tight. The nerve then fires warning signals: tingling in the thumb, index and middle fingers, shooting pains up the forearm, hand weakness and night-time numbness that wakes you from sleep. If pressure lasts too long, the nerve coating frays like worn phone-charger cable and permanent weakness may follow. Early, well-chosen treatment can usually stop this cascade and even reverse the damage.

Types

• Idiopathic (primary) – the tunnel is tight for no obvious medical reason; often both wrists are involved.

• Secondary – compression driven by another condition such as diabetes, thyroid disease, pregnancy-related fluid retention or a wrist fracture.

• Acute CTS – sudden swelling after trauma, bleeding or infection creates a medical emergency with explosive pain and numbness.

• Chronic CTS – the slow, classic form that unfolds over months to years.

• Severity grades (mild, moderate, severe) – based on nerve-conduction study (NCS) findings and the amount of muscle wasting.

• Occupational vs. non-occupational – classified by whether forceful, repetitive workplace tasks or vibrating tools are the main trigger.

Each “type” matters because it guides urgency of care and whether simply modifying activities, adding medical treatment, or moving quickly to surgery will give the best result. aaos.org

Causes

1. Repetitive wrist work – Keyboarding, assembly-line jobs, chopping or twisting builds hour-after-hour tendon friction that inflames synovium. pmc.ncbi.nlm.nih.gov

2. Forceful grip & vibrating tools – Jackhammers, grinders and staplers transmit vibration that doubles median-nerve oedema. researchgate.net

3. Wrist fracture or dislocation – Bone fragments or callus shrink the tunnel and can trigger the “acute” subtype. mayoclinic.org

4. Pregnancy – Fluid retention during the third trimester raises tunnel pressure; symptoms usually resolve postpartum. mayoclinic.org

5. Menopause & hormone shifts – Oestrogen decline promotes fluid shifts and connective-tissue thickening, especially in small-boned women. mayoclinic.org

6. Obesity – Every 5-unit rise in BMI increases CTS odds by roughly 50 %. Adipose volume and low-grade inflammation both contribute. verywellhealth.comfrontiersin.org

7. Type 1 & Type 2 diabetes – Hyperglycaemia damages Schwann cells and causes endoneurial oedema; meta-analysis shows a 90 % higher risk. journals.plos.org

8. Hypothyroidism – Myxoedema thickens the subsynovial connective tissue, mechanically squeezing the nerve. pubmed.ncbi.nlm.nih.gov

9. Rheumatoid arthritis – Inflamed synovium fills the tunnel; erosive bone changes shrink it further. mayoclinic.org

10. Gout & tophaceous deposits – Urate crystals form firm masses that directly compress the nerve. pmc.ncbi.nlm.nih.gov

11. Kidney failure & haemodialysis – β-2-microglobulin amyloid collects around flexor tendons. mayoclinic.org

12. Amyloidosis (transthyretin) – Bilateral CTS can precede cardiac amyloidosis by years. en.wikipedia.org

13. Acromegaly – Excess growth hormone thickens synovium; Swedish registry data show a six-fold jump in CTS surgery. pubmed.ncbi.nlm.nih.gov

14. Hereditary neuropathy with pressure palsies (HNPP) – A PMP22 gene deletion makes nerves unusually pressure-sensitive. en.wikipedia.org

15. Tenosynovitis of flexor tendons – Overuse or inflammatory disease enlarges tendon sheaths. mayoclinic.org

16. Space-occupying tumours (ganglion, lipoma) – Rare but classic surgical surprises compressing the median nerve. en.wikipedia.org

17. Congenitally narrow carpal tunnel – Some people simply have less room; women are affected three times more often. verywellhealth.com

18. Smoking – Vasoconstriction and chronic inflammation may double CTS risk in heavy smokers (multiple cohort studies). pmc.ncbi.nlm.nih.gov

19. Systemic lupus & mixed connective-tissue disease – Tendon sheath vasculitis thickens synovium and raises intracarpal pressure. pmc.ncbi.nlm.nih.gov

20. Acute haemorrhage (anticoagulation mishap or trauma) – A sudden blood clot inside the tunnel causes very rapid onset of numbness and pain. link.springer.com

Symptoms

Each paragraph explains what the patient feels & why in everyday language.

1. Numbness in thumb, index, middle, and half of ring finger – sensory fibres lose conduction first, so digits feel “asleep.” my.clevelandclinic.org

2. Tingling or “pins-and-needles” – mild axon hypoxia produces erratic nerve firing perceived as fizzing under the skin.

3. Burning hand pain at night – wrist flexion during sleep spikes tunnel pressure; patients wake to shake or “flick” the hand for relief. my.clevelandclinic.org

4. Electric-shock zaps into fingertips – sudden wrist motion triggers ectopic discharges along partially demyelinated fibres.

5. Hand feels swollen even when it looks normal – sensory mismatch from impaired proprioceptive fibres gives a “puffy” illusion.

6. Weak grip – motor fibres to the thenar muscles fatigue; dropping coffee mugs becomes common.

7. Clumsiness with buttons or zippers – loss of fine touch and proprioception hampers dexterity.

8. Thenar muscle wasting – long-standing denervation shrinks the thumb-base bulk, noticed when comparing hands side-by-side.

9. Loss of thumb opposition strength – abductor pollicis brevis is median-nerve-dependent; turning keys or unscrewing jars is harder.

10. Pain radiating to forearm or even shoulder – central sensitisation and heightened nerve root excitability spread discomfort proximally.

11. Dry or shiny palmar skin – sympathetic autonomic fibres supplying sweat glands can fail.

12. Cold fingertips – vasomotor tone is disturbed, so blood vessels constrict inappropriately.

13. “Flick sign” relief – shaking the hand momentarily reduces tunnel fluid pressure, easing symptoms.

14. Difficulty holding a phone – prolonged wrist extension triggers numbness within minutes.

15. Finger cramping – flexor tendons glide less smoothly through the inflamed tunnel.

16. Waking more than once nightly – nocturnal symptom clusters disrupt deep sleep, leading to fatigue.

17. Morning stiffness that eases after movement – venous pooling overnight adds oedema; motion pumps it out.

18. Temperature sensitivity – impaired small fibres blunt warm/cold discrimination.

19. Accidental finger cuts or burns – dulled sensation stops pain warning signals.

20. Hand feels weak after knitting/typing – repetitive finger work exhausts partially blocked motor units sooner than normal. my.clevelandclinic.orgjospt.org

Diagnostic tests

A. General / Physical-examination tests

1. Visual inspection – looking for thenar wasting or dry, shiny skin hints at chronic denervation.

2. Palpation for swelling/tenderness – detects synovitis or a hidden ganglion.

3. Grip-strength dynamometry – objective way to track weakness over time.

4. Pinch-strength test – assesses fine motor loss important for writing and picking up coins.

5. Thumb opposition (manual muscle test) – isolates abductor pollicis brevis power.

6. Semmes-Weinstein monofilament test – thin nylon filaments measure loss of light-touch threshold. en.wikipedia.org

7. Two-point discrimination – determines how many millimetres apart two pricks must be felt as separate; >6 mm suggests sensory impairment. en.wikipedia.org

8. Vibration (128 Hz tuning-fork) test – large-fibre function often fails early.

13. Durkan’s Carpal Compression test – examiner presses thumbs over the tunnel for 30 s; sensitivity 87–91 %. en.wikipedia.org

14. Tinel’s sign – gentle percussion over the median-nerve path elicits tingling. stanfordmedicine25.stanford.edu

15. Scratch-Collapse test – brief skin scratch followed by resisted shoulder external rotation; sudden “collapse” indicates CTS. pmc.ncbi.nlm.nih.gov

16. Hand-Elevation test – raising hands overhead for 2 min produces paraesthesia sooner in CTS than in controls. physiotutors.com

17. Median-nerve Upper-Limb-Tension test – sequential shoulder & elbow positions stretch the nerve, revealing latent entrapment.

18. Closed-fist wrist-flexion test – patient makes a fist and flexes wrist; intracarpal pressure spikes faster than standard Phalen.

19. Ischaemic (tourniquet) test – transient venous congestion provokes numbness in <30 s in severe CTS.

20. CTS-6 clinical score – composite of numbness pattern, symptom relief patterns and two provocative tests, validated against EMG.

Non-Pharmacological Treatments

To keep the style clear, each therapy below is written in three short paragraphs: Description, Purpose, How It Works. The first fifteen are hands-on physiotherapy or electro-therapy; the next five are exercise-based, five are mind–body, and the final five are self-management skills.

 Physiotherapy & Electro-Therapy

1. Neutral wrist splinting
   Description – A lightweight thermoplastic brace worn mainly at night keeps the wrist straight.
   Purpose – Prevents sleep-time flexion that spikes tunnel pressure eight-fold.
   Mechanism – Keeps the flexor tendons from bow-stringing and gives the swollen median nerve room to breathe. Strong guideline support shows splints improve symptoms within 2–6 weeks. aaos.org

2. Median nerve gliding
   Gentle five-step arm-to-fingertip motions “floss” the nerve through its sheath, easing sticking points. Randomised trials show better numbness scores than sham exercise. pubmed.ncbi.nlm.nih.gov

3. Flexor-tendon gliding
   A six-pose finger routine moves each flexor tendon separately to reduce tendon bulk and adhesions in the tunnel.

4. Therapeutic ultrasound
   Pulsed 1 MHz ultrasound, 0.8–1 W/cm² for 5–10 minutes, three times a week for 6 weeks, warms deep tissue and improves local blood flow. Meta-analysis finds short-term pain relief and faster nerve-conduction speed. pubmed.ncbi.nlm.nih.gov

5. Low-level laser therapy (LLLT)
   Red-light (630–860 nm) lasers at 3–6 J/cm² modulate cellular energy (ATP) and micro-circulation, helping nerve healing.

6. Transcutaneous electrical nerve stimulation (TENS)
   Skin electrodes deliver pulsed current that blocks pain signals (“gate control”). Home use 30 minutes twice daily eases nocturnal symptoms.

7. Ketoprofen phonophoresis
   Ultrasound is used to push 2.5 % ketoprofen gel across the skin, combining NSAID action with deep tissue heating. Moderate evidence of benefit. aaos.org

8. Dexamethasone iontophoresis
   A mild electric field drives steroid ions into the carpal tunnel—useful if injections are not possible.

9. Extracorporeal shock-wave therapy (ESWT)
   Low-energy acoustic pulses stimulate angiogenesis and anti-inflammatory pathways; sessions once weekly for 3–4 weeks improve grip strength in pilot trials.

10. Paraffin wax bath
    Immersing the hand in 52 °C melted wax for 15 minutes relaxes tight flexor tendons and increases circulation.

11. Cryotherapy (ice massage)
    Three-minute ice rubs after computer or assembly-line shifts calm tendon swelling and prolong pain-free typing time.

12. Manual carpal bone mobilisation
    A therapist glides the lunate and capitate bones, decompressing the floor of the tunnel and loosening the ligament roof.

13. Soft-tissue and myofascial release
    Slow thumb or tool strokes break tender trigger points in the forearm that perpetuate protective wrist flexion.

14. Mirror therapy
    Moving the non-painful hand in front of a mirror tricks the brain into sensing normal movement in the affected hand, dampening central pain sensitisation. Randomised data show reduced pain intensity after four weeks. sciencedirect.com

15. Virtual-reality–mediated training
    Immersive VR games that embed nerve-and-tendon glides improve adherence and boost function beyond video-assisted drills. minervamedica.it

Exercise Therapies

16. Forearm flexor/extensor stretches – 20-second holds, five reps each, lengthen tight muscles, lowering resting tunnel pressure.

17. Isometric grip strengthening – Squeezing a soft ball for 5 seconds trains the thenar muscles without shear stress on the nerve.

18. Eccentric wrist-flexor lowering – Using a light dumb-bell, the wrist is slowly lowered from flexion to extension; eccentric load pumps nutrient-rich blood into the tunnel.

19. Scapular-setting drills – Drawing the shoulder blades down and back aligns the entire nerve path and reduces traction on the median nerve.

20. Cervical glide with neural mobilisation – Sliding the head and neck laterally while doing finger extension improves overall nerve mobility from spine to wrist.

Mind-Body Therapies

21. Yoga-based regimen – Twice-weekly Iyengar-style poses (e.g., modified plank, cobra) relieved pain more than splints in a JAMA trial. pubmed.ncbi.nlm.nih.gov

22. Tai Chi / Qigong wrist flow – Slow circular movements relax forearm fascia and foster mindful posture.

23. Mindfulness-based stress reduction (MBSR) – Guided body-scan meditations lower sympathetic tone, dampening neuro-inflammation that heightens pain.

24. Biofeedback for wrist posture – A small sensor beeps if the wrist angles beyond 15°; users quickly learn to stay in the “green zone.”

25. Guided imagery – Visualising cool, roomy space around the nerve quiets central amplifiers of pain.

Educational Self-Management

26. Ergonomic workstation redesign – Split keyboard, negative-tilt tray and low-force mouse reduce sustained flexion and pinch forces.

27. Activity pacing & micro-breaks – 30-second shake-out breaks every 30 minutes prevent cumulative tendon swelling.

28. Tool-grip training & adaptive devices – Padded handles on screwdrivers or knitting needles spread the load, cutting peak tunnel force by 60 %.

29. Lifestyle counselling – Weight loss and tight glucose control lower systemic inflammation, directly easing tunnel pressure in diabetes.

30. Sleep hygiene with splint compliance – A bedtime ritual—warm wash, gentle stretch, splint on—improves comfort and reduces brace “abandonment.”

When to See a Doctor Immediately

• Numbness or pain wakes you nightly despite two weeks of splinting.

• Fingers feel “dead” in the morning or drop objects often.

• Muscle at the thumb base looks hollow (thenar wasting).

• Symptoms extend above the elbow.

• Diabetes or thyroid issues complicate healing.

• You are pregnant and symptoms worsen quickly.

• Fever, redness or sudden swelling suggests infection, not CTS.

---

Key “Do’s and Don’ts”

Do

1. Do keep your wrist neutral during sleep.

2. Do stretch flexors before long phone or game sessions.

3. Do log symptom patterns in a diary; patterns guide treatment.

4. Do adjust workstation height so forearms stay parallel to the floor.

5. Do ask for a steroid injection if splint and exercises fail after six weeks.

Don’t
6. Don’t sleep with your hand curled under your cheek.
7. Don’t ignore constant tingling—delayed care risks permanent nerve loss.
8. Don’t grip tools tighter than necessary; use larger handles.
9. Don’t overuse NSAIDs; combine with stomach protection if long-term.
10. Don’t smoke—nicotine clamps tiny vessels that feed the nerve.

Frequently Asked Questions (FAQs)

1. Can Carpal Tunnel Syndrome go away on its own?
   Mild, pregnancy-related CTS often fades after delivery, but most cases need splints, exercises or injections to settle fully.

2. How long should I wear a night splint?
   Use it every night for at least six weeks; many people continue part-time thereafter because it feels comfortable.

3. Will typing cause permanent damage?
   No—typing itself rarely injures the nerve, but poor keyboard angle and never resting can. Correct setup prevents harm.

4. Are steroid injections dangerous?
   One or two injections have tiny long-term risk. Repeated shots (>3) may weaken ligament fibres.

5. Do copper bracelets or magnets work?
   There is no reputable evidence they relieve tunnel pressure.

6. Can hand exercises cure severe CTS?
   They help mild-to-moderate disease but cannot reverse advanced nerve loss; surgery is then more effective.

7. Is surgery done under general anaesthetic?
   Usually not. Local anaesthetic plus light sedation is common; endoscopic and ultrasound releases can be “wide-awake.”

8. How long is recovery after open release?
   Most patients regain light use in two weeks and full grip in six to twelve weeks.

9. Will I lose hand strength after ligament cutting?
   Studies show no long-term weakness because other wrist structures share the load.

10. Can children get CTS?
    Very rarely—usually linked to genetic lysosomal storage diseases or congenital bone disorders.

11. Why are my symptoms worse at night?
    Sleeping wrists often flex unknowingly; fluid also redistributes when lying flat, raising tunnel pressure.

12. Does diabetes make CTS worse?
    Yes. High glucose stiffens tendon sheaths and starves nerves; strict control speeds recovery.

13. Is PRP better than steroid?
    Network meta-analysis suggests PRP gives longer relief, but it costs more and still lacks large long-term trials. pubmed.ncbi.nlm.nih.gov

14. What if splints hurt my fingers?
    Ask for a custom-moulded thermoplastic brace or try a soft fabric wrap with a metal stay. Comfort improves adherence.

15. Can I prevent recurrence after surgery?
    Yes—keep good ergonomics, stretch daily and manage weight and sugar; true recurrence is rare (<5 %).
