Physiotherapy Management of Peripheral Vascular Disorders (PVD)

1. Assessment Before Treatment

• Ankle-Brachial Index (ABI): Normal 0.9-1.3; ABI 0.6-0.9 = mild/moderate PAD; ABI < 0.5 = severe ischemia; guides exercise and compression safety
• Clinical staging (Fontaine/Rutherford): Determines level of intervention
• Presence of wounds, ulcers, gangrene: Guides wound care approach
• Cardiopulmonary fitness: For safe exercise prescription
• Venous vs. arterial etiology: Compression is contraindicated in severe arterial disease (ABI ≤ 0.5)

2. Physiotherapy for Peripheral Arterial Disease (PAD) / Intermittent Claudication

A. Supervised Exercise Therapy (SET) - First-Line Treatment

B. Home-Based and Community-Based Exercise

• Structured walking prescription with specific targets
• Use of step counters or diaries for monitoring
• Regular contact with healthcare provider (phone/telehealth)
• Pain guidance: walk until moderate pain (3-4/10), rest, repeat

C. Other Exercise Modalities

• Nordic walking (poles): Reduces cardiovascular load while increasing distance
• Cycling / Arm ergometry: For patients with severe claudication unable to walk
• Resistance training: Adjunct to aerobic exercise; improves overall function
• Upper extremity exercise in Buerger's disease: Maintains overall conditioning

D. Buerger's Exercises (Postural Exercises for Arterial Insufficiency)

1. Patient lies supine - elevate legs 45-90° until they blanch (1-2 min)
2. Dangle legs dependently over bed edge until rubor appears (2-5 min)
3. Lie flat, cover feet with warm cloth (5 min)
4. Repeat 3-4 cycles, 3-4 times daily

3. Physiotherapy for Chronic Venous Insufficiency (CVI) and Venous Ulcers

A. Compression Therapy

• Elastic compression stockings
• Inelastic (short-stretch) bandages (better for active ulcers)
• Multilayer compression bandages
• Intermittent Pneumatic Compression (IPC): Sequential inflation device; reduces edema, promotes venous ulcer healing, first-line when lymphatic impairment coexists

B. Exercise for CVI

• Calf muscle pump exercises: Ankle plantarflexion/dorsiflexion ("ankle pumps") in sitting or lying - activate the venous pump in the calf, reducing venous pooling
• Walking: Improves calf pump function and reduces venous hypertension
• Leg elevation: Elevate legs above heart level several times daily to reduce edema
• Avoid prolonged standing or sitting

C. Wound Care for Venous/Arterial Ulcers

• Debridement: Surgical or enzymatic removal of necrotic tissue
• Moist wound dressings: Promote granulation tissue
• Offloading/pressure relief: Total-contact casting, orthoses for diabetic/arterial foot ulcers
• Skin care: Daily moisturization with emollients, barrier preparations; prevent skin breakdown
• Infection control: Antibiotics only with signs of active cellulitis

4. Patient Education and Risk Factor Modification

• Smoking cessation: Smoking causes up to 50% of all PAD and dramatically worsens outcomes post-surgery; primary target for intervention (Mulholland Surgery, 7e)
• Foot care education: Daily inspection, appropriate footwear, reporting early ulcers - critical in diabetic PVD patients
• Weight management and diabetes control
• Positioning: Avoid elevating legs in arterial disease (worsens ischemia); encourage elevation in venous disease
• Thermal protection: Use warm (not hot) water, avoid direct heat in arterial insufficiency (impaired sensation)
• Activity modification: Encourage regular, graduated activity; avoid prolonged immobility

5. Physiotherapy for Specific Conditions

Raynaud's Disease

• Cold avoidance: Gloves, layered clothing, whole-body warming
• Biofeedback training: Temperature biofeedback to teach peripheral vasodilation
• Sympathetic desensitization exercises
• Smoking cessation is mandatory

Buerger's Disease (Thromboangiitis Obliterans)

• Buerger's exercises (see above)
• Absolute smoking cessation
• Graduated walking program
• Wound care for digital ulcers

Post-Revascularization Rehabilitation

6. Multidisciplinary Context

• Vascular surgery: Revascularization decisions; consultation before amputation
• Pharmacology: Antiplatelet therapy, statins, cilostazol (for claudication), rivaroxaban + aspirin in high-risk PAD
• Wound care teams / podiatry
• Cardiology: Management of coexisting cardiovascular disease (most PAD patients have concurrent coronary/cerebrovascular disease)

Physiotherapy Management of Peripheral Vascular Disorders

Classification of PVD

• Arterial: PAD, Buerger's disease, Raynaud's
• Venous: CVI, varicose veins, venous ulcers
• Mixed: Arteriovenous + lymphatic involvement

Assessment

ABI < 0.5 = compression therapy contraindicated

I. Arterial Disease (PAD / Claudication)

A. Supervised Exercise Therapy (SET) - 1st Line

• Mode: Treadmill walking (preferred)
• Intensity: Walk to moderate-to-severe claudication pain → rest → repeat
• Duration: 30-60 min/session
• Frequency: 3x/week
• Program length: Minimum 12 weeks
• Evidence: Class I, Level A - 2024 AHA/ACC PAD Guideline

B. Home / Community-Based Exercise

• Structured walking prescription with targets
• Step counters / exercise diaries
• Regular physiotherapist follow-up (phone/telehealth)
• Walk until pain grade 3-4/10, rest, repeat

C. Buerger's Exercises (Arterial insufficiency)

1. Elevate legs 45-90° → blanching (1-2 min)
2. Dangle legs dependently → rubor appears (2-5 min)
3. Lie flat, cover feet with warm cloth (5 min)
4. Repeat 3-4 cycles, 3-4x daily

Promotes collateral circulation; used in Buerger's disease and mild-moderate PAD

D. Other Modalities

• Nordic walking: Poles reduce CV load, increase distance
• Cycling / Arm ergometry: When walking severely limited
• Resistance training: Adjunct to aerobic; improves function
• TENS / IPC: Adjuncts for pain and perfusion

II. Venous Disease (CVI / Venous Ulcers)

A. Compression Therapy - Mainstay

• Elastic stockings
• Inelastic (short-stretch) bandages - best for active ulcers
• Multilayer compression bandages
• IPC (Intermittent Pneumatic Compression) - for lymphedema/phlebolymphedema

Rule: Never apply stocking to a swollen leg - reduce edema first with wraps

B. Exercise for CVI

• Ankle pump exercises (plantarflexion/dorsiflexion) - activate calf muscle pump
• Walking - reduces venous hypertension
• Leg elevation above heart level - multiple times daily
• Avoid prolonged standing/sitting

C. Wound / Ulcer Care

• Debridement (surgical or enzymatic)
• Moist wound dressings
• Offloading / total-contact casting (arterial/diabetic ulcers)
• Antibiotics only if active cellulitis

III. Specific Conditions

Raynaud's Disease

• Cold avoidance (gloves, layered clothing)
• Temperature biofeedback training
• Sympathetic desensitization
• Smoking cessation (mandatory)

Buerger's Disease (TAO)

• Absolute smoking cessation - primary treatment
• Graduated walking program
• Wound care for digital ulcers

Post-Revascularization

• SET is recommended after surgery/stenting (Class I, Level A)
• Effects are additive to surgical outcomes

IV. Patient Education

V. Goals of Physiotherapy

• Improve pain-free and maximum walking distance
• Enhance collateral circulation
• Reduce edema and venous hypertension
• Promote ulcer healing
• Prevent amputation
• Improve QOL and functional independence
• Reduce cardiovascular risk
