Foot Drop — বাংলায় ক্লিনিক্যাল ও প্রেস্ক্রিপশন-ভিত্তিক নোট

Important: Foot drop নিজে কোনো “disease” নয়; এটি একটি clinical sign। অর্থাৎ underlying nerve/root/brain/muscle problem খুঁজে বের করাই মূল চিকিৎসা। শুধু painkiller বা vitamin দিয়ে foot drop cure হয় না। Acute/progressive foot drop হলে Neurology/Neurosurgery/Orthopedics referral জরুরি।

---

1. Definition / সংজ্ঞা

Foot drop হলো পায়ের ankle dorsiflexion weakness/paralysis—রোগী পায়ের সামনের অংশ বা আঙুল ওপরে তুলতে পারে না, ফলে হাঁটার সময় পায়ের আঙুল মাটিতে লেগে যায় এবং high-steppage gait দেখা যায়। এটি সাধারণত L5 nerve root, sciatic nerve, common peroneal/fibular nerve, deep peroneal nerve বা কখনো brain/spinal cord lesion-এর কারণে হয়।

---

2. Cause / কারণগুলো — Bangla points

A. Common peroneal/fibular nerve compression — সবচেয়ে common peripheral cause

• Fibular head/neck-এর কাছে nerve superficial থাকে, তাই সহজে চাপ লাগে।
• কারণ:
  • দীর্ঘ সময় পা ক্রস করে বসা
  • দীর্ঘ সময় squatting/kneeling
  • tight plaster/cast/brace
  • rapid weight loss
  • prolonged bed rest/ICU stay
  • knee trauma, fracture, dislocation
  • diabetes থাকলে nerve compression-এর risk বেশি
• Clinical clue: ankle dorsiflexion + toe extension + eversion দুর্বল, lateral leg ও dorsum of foot-এ numbness/tingling।

B. L5 radiculopathy

• Lumbar disc prolapse, spinal stenosis, spondylolisthesis, foraminal compression।
• Clinical clue: কোমর থেকে buttock/thigh হয়ে leg/foot-এ radiating pain, big toe extension দুর্বল; inversion-ও দুর্বল হতে পারে।

C. Sciatic neuropathy / lumbosacral plexopathy

• Hip trauma/surgery, pelvic tumor, radiation, injection injury, pelvic surgery।
• Clinical clue: পুরো foot sensory loss, plantarflexion/inversion-ও দুর্বল হলে sciatic involvement ভাববেন।

D. Central nervous system cause

• Stroke/CVA, multiple sclerosis, spinal cord lesion।
• Clinical clue: hyperreflexia, Babinski, spasticity, circumduction gait, upper limb weakness, dysphasia/aphasia।

E. Peripheral neuropathy / metabolic cause

• Diabetes mellitus
• Vitamin B12 deficiency
• Alcohol-related neuropathy
• CKD/uremia
• Chemotherapy-induced neuropathy, যেমন vincristine, platinum drugs, taxanes
• Hypothyroidism

F. Autoimmune / infective cause

• Guillain–Barré syndrome
• Vasculitic mononeuritis multiplex
• Leprosy/Hansen disease
• Rheumatoid vasculitis, PAN, GPA ইত্যাদি

G. Traumatic / musculoskeletal cause

• Knee dislocation, fibular fracture
• Compartment syndrome
• Tibialis anterior tendon rupture
• Post-operative nerve injury

H. Hereditary / degenerative

• Charcot–Marie–Tooth disease
• Motor neuron disease/ALS

---

3. Symptoms / লক্ষণগুলো — Bangla points

• পায়ের আঙুল মাটিতে লেগে যায় — হাঁটার সময় toe dragging।
• High-steppage gait — রোগী হাঁটার সময় হাঁটু বেশি উঁচু করে পা তোলে।
• Slapping gait — পা মাটিতে “চাপড়” দিয়ে পড়ে।
• Heel walking করতে পারে না — dorsiflexion weakness-এর sensitive sign।
• Frequent tripping/falling — পড়ে যাওয়ার ঝুঁকি বেড়ে যায়।
• Weakness
  • ankle dorsiflexion দুর্বল
  • big toe extension দুর্বল
  • peroneal lesion হলে eversion দুর্বল
• Numbness/tingling
  • common peroneal lesion: lateral leg + dorsum of foot
  • deep peroneal lesion: first web space
• Pain
  • L5 radiculopathy হলে low back pain with radiation
  • peroneal compression হলে fibular head-এর কাছে pain/tenderness
• Muscle wasting — chronic হলে anterior compartment wasting।
• Bilateral foot drop হলে polyneuropathy, GBS, spinal canal lesion, motor neuron disease ভাবতে হবে।

Red flag symptoms — emergency

• হঠাৎ foot drop + মুখ বেঁকে যাওয়া/হাত দুর্বল/কথা জড়িয়ে যাওয়া → stroke
• low back pain + bladder/bowel dysfunction + saddle anesthesia → cauda equina
• দ্রুত bilateral weakness + areflexia + breathing difficulty → GBS
• severe trauma/leg swelling/চরম pain → fracture/compartment syndrome

---

4. Clinical diagnosis — bedside specific approach

A. History

• Onset: sudden না gradual?
• Pain আছে কি? low back/radicular pain?
• Leg crossing, squatting, kneeling, plaster/cast, ICU stay, rapid weight loss?
• Diabetes, alcohol, B12 deficiency, CKD?
• Trauma/knee/hip/spine surgery?
• Leprosy skin patch, sensory loss, thickened nerve?
• Cancer, weight loss, fever?
• Drug history: chemotherapy, anti-TB drugs, neurotoxic drugs।

B. Gait examination

• High-steppage gait
• Slapping foot
• Toe dragging
• Circumduction gait থাকলে UMN lesion ভাবুন।

C. Motor examination — MRC grading 0–5

• Ankle dorsiflexion: tibialis anterior, deep peroneal nerve, L4–L5
• Great toe extension: extensor hallucis longus, L5
• Ankle eversion: superficial peroneal nerve
• Ankle inversion: tibialis posterior, tibial nerve, L5
  • Important: inversion normal কিন্তু eversion weak হলে peroneal neuropathy বেশি likely। inversion weak হলে L5 radiculopathy/sciatic neuropathy ভাববেন।
• Plantarflexion: S1/tibial nerve
• MRC scale দিয়ে objective documentation করুন।

D. Sensory examination

• First web space → deep peroneal nerve
• Dorsum of foot + lateral leg → superficial/common peroneal nerve
• Medial foot → L4/saphenous
• Sole → tibial nerve

E. Reflex + UMN signs

• Knee jerk: L3–L4
• Ankle jerk: S1
• Babinski, clonus, hyperreflexia → central lesion।

F. Special tests

• Tinel sign at fibular neck
• Straight leg raise / slump test for radiculopathy
• Palpate fibular head mass/ganglion cyst
• Spine examination
• Peripheral pulses + skin inspection

---

5. Investigations — specificভাবে কী করবেন

First-line

• NCS + EMG: lesion peroneal nerve, L5 root, sciatic nerve, plexus—কোথায় তা localize করে; severity/prognosis জানায়। EMG denervation দেখালে axonal injury বোঝায়।
• X-ray pelvis/knee/tibia-fibula/ankle: trauma, fracture, dislocation, bony lesion।
• MRI lumbosacral spine: back pain, radicular pain, progressive weakness, suspected disc prolapse/stenosis/cauda equina।
• MRI knee/fibular head অথবা ultrasound: ganglion cyst, tumor, nerve swelling/compression। Mayo Clinic-ও foot drop workup-এ X-ray, US, CT, MRI এবং EMG/NCS উল্লেখ করেছে।

Laboratory workup — cause অনুযায়ী

• CBC, ESR, CRP
• RBS/FBS, HbA1c
• Serum vitamin B12, folate
• TSH
• Urea, creatinine, electrolytes
• LFT
• CK — myopathy সন্দেহে
• ANA, RF, ANCA, complement — vasculitis/autoimmune সন্দেহে
• HIV, HBV, HCV — mononeuritis multiplex সন্দেহে
• Leprosy suspected হলে slit-skin smear/skin biopsy/nerve thickening evaluation

---

6. Differential diagnosis

• Common peroneal/fibular neuropathy
• L5 radiculopathy
• Sciatic neuropathy
• Lumbosacral plexopathy
• Stroke/UMN lesion
• Diabetic polyneuropathy
• Charcot–Marie–Tooth disease
• Guillain–Barré syndrome
• ALS/motor neuron disease
• Tibialis anterior tendon rupture
• Compartment syndrome
• Functional neurological disorder/conversion disorder
  Foot drop-এর differential diagnosis-এ UMN lesion, severe L5 radiculopathy, lumbar plexus dysfunction, diabetic amyotrophy, cerebellar/ataxic gait, psychological causes উল্লেখযোগ্য।

---

7. Complications — বাংলায় সহজভাবে

• পড়ে যাওয়া: পা মাটি থেকে clear না হওয়ায় fall, ankle sprain, fracture হতে পারে।
• Contracture: দীর্ঘদিন dorsiflexion না হলে calf/Achilles tight হয়ে equinus deformity হতে পারে।
• Pressure ulcer/skin injury: sensory loss থাকলে পায়ের ক্ষত টের পায় না।
• Brace injury: poorly fitted AFO/brace abrasions/ulcer করতে পারে।
• Muscle wasting: denervation দীর্ঘদিন থাকলে muscle atrophy।
• Permanent weakness: axonal loss বা neurotmesis হলে recovery দীর্ঘ/অসম্পূর্ণ হতে পারে।
• Chronic neuropathic pain: burning, tingling, electric shock-like pain।
• Functional disability: হাঁটা, সিঁড়ি ওঠা, কাজ, driving, daily activity সীমিত হয়। Complication হিসেবে fall risk, ulcer, brace abrasion এবং prognosis injury severity-এর ওপর নির্ভর করে—StatPearls এগুলো উল্লেখ করেছে।

8. Treatment & Management

A. Non-pharmacological — core treatment

1. Underlying cause treat করুন
   • peroneal compression হলে pressure remove
   • disc prolapse/stenosis হলে spine evaluation
   • diabetes/B12 deficiency control
   • stroke/GBS/leprosy/vasculitis হলে disease-specific treatment
2. AFO / ankle-foot orthosis
   • পা neutral position-এ রাখে
   • toe dragging কমায়
   • fall prevent করে
     Braces/splints, physical therapy, nerve stimulation এবং surgery cause অনুযায়ী ব্যবহৃত হয়।
3. Physiotherapy
   • dorsiflexor strengthening
   • calf/Achilles stretching
   • range-of-motion exercise
   • gait training
   • balance training
   • home exercise program
4. Functional electrical stimulation — selected cases
   • dorsiflexor muscle activation assist করতে পারে।
5. Surgery — selected cases
   • traumatic nerve transection হলে early nerve repair
   • compressive lesion হলে decompression/neurolysis
   • chronic/permanent foot drop হলে tendon transfer
   • fixed deformity হলে fusion
     Traumatic nerve transection-এর ক্ষেত্রে early repair এবং chronic/permanent ক্ষেত্রে tendon transfer/fusion options হিসেবে উল্লেখ আছে।

Pattern 2: L5 radiculopathy/disc prolapse with foot drop

• Urgent MRI LS spine if progressive motor deficit
• AFO + physiotherapy
• NSAID short course ± PPI if not contraindicated
• Severe/progressive weakness → neurosurgery/spine referral
• Gabapentin/Pregabalin routine sciatica-তে avoid/reassess, কারণ NICE no overall benefit + harm বলেছে।

Pattern 3: Diabetic neuropathy + foot drop

• HbA1c control
• Pregabalin/Gabapentin/Duloxetine/Amitriptyline — painful neuropathy থাকলে
• Mecobalamin only if B12 deficiency বা neuropathy support indication
• Foot care + AFO + physiotherapy

Pattern 4: B12 deficiency neuropathy

11. Prevention — কীভাবে প্রতিরোধ করবেন

• দীর্ঘ সময় পা ক্রস করে বসবেন না।
• prolonged squatting/kneeling এড়ান।
• plaster/cast/brace tight হলে দ্রুত review।
• ICU/bedridden patient: regular repositioning + pressure area care।
• Diabetes control: HbA1c target individualize।
• Alcohol avoid/limit; nutrition adequate রাখুন।
• B12 deficiency risk থাকলে check করুন—metformin/PPI long-term use, vegan diet, malabsorption।
• Proper footwear + home fall prevention:
  • floor clutter সরান
  • loose rugs avoid
  • stair/light adequate
  • electrical cord walkway থেকে সরান
    Mayo Clinic foot drop-এ fall prevention-এর জন্য clutter/rug/cord/light/stairs safety উল্লেখ করেছে।
• Chemotherapy/neurotoxic drug use হলে neuropathy monitoring।
• Early foot drop হলে দেরি না করে NCS/EMG/MRI evaluation।

1. Overview / Summary

Foot drop হলো dorsiflexor weakness-এর clinical sign। সবচেয়ে common cause হলো common peroneal nerve compression এবং L5 radiculopathy। Clinical diagnosis করতে gait, MRC motor testing, sensory mapping, reflex/UMN signs জরুরি। Investigation-এর key হলো NCS/EMG এবং cause অনুযায়ী MRI spine/knee, ultrasound, X-ray, lab workup। Treatment-এর core হলো cause treatment + AFO + physiotherapy + fall prevention; medicine শুধু pain/neuropathy/inflammation/deficiency control করে।

---

2. Actionable Plan / Steps

1. Confirm foot drop: heel walking, dorsiflexion MRC grade, toe extension, eversion/inversion test।
2. Localize lesion: peroneal nerve vs L5 radiculopathy vs sciatic/plexus vs CNS।
3. Order key tests: NCS/EMG; MRI LS spine if back/radicular/progressive weakness; US/MRI knee if fibular head lesion suspected।
4. Start safety management: AFO, physiotherapy, fall prevention, skin care।
5. Pain control: neuropathic pain থাকলে pregabalin/gabapentin/duloxetine/amitriptyline cause অনুযায়ী; NSAID/paracetamol short course for nociceptive pain।
6. Treat cause: diabetes/B12/leprosy/vasculitis/disc prolapse/stroke/trauma অনুযায়ী targeted management।
7. Refer urgently: acute/progressive weakness, cauda equina sign, stroke sign, GBS suspicion, trauma, severe radiculopathy with motor deficit।
