Long-Term Goals (Months 2–12+)

• Full upper extremity strength and endurance
• Normal neuromuscular control of the shoulder girdle
• Prevention or management of lymphedema
• Return to recreational and occupational activities
• Optimize quality of life and reduce cancer-related fatigue
• Psychological well-being and social reintegration

---

2. PHASES OF REHABILITATION AFTER BREAST SURGERY

---

Phase 1 — Acute/Inpatient Phase (Days 1–7)

• Deep breathing exercises and incentive spirometry (prevent atelectasis, pain management)
• Gentle hand, wrist, and elbow ROM — full range permitted immediately
• Shoulder ROM is restricted if drains are in place — typically limited to 90° shoulder flexion/abduction to prevent seroma and drain dislodgement
• Positioning: elevate arm on pillow, avoid dependent positioning
• Ambulation and lower limb exercises to prevent DVT
• Edema monitoring — baseline arm circumference measurements

• Lymphedema precautions (avoid BP cuffs, blood draws, tight clothing on affected arm)
• Signs of infection, seroma, or hematoma
• Activity restrictions (no lifting >1 kg initially)
• Scar care post-wound closure

• No aggressive shoulder stretching while drains are present
• No resistive exercise
• Avoid extreme positions that increase seroma risk

---

Phase 2 — Early Rehabilitation (Weeks 2–6, Post-Drain Removal)

• Restore full shoulder ROM progressively
• Normalize scapulothoracic rhythm
• Begin soft tissue mobilization around incision
• Gentle aerobic reconditioning

• ROM measured at each visit (goniometry)
• Limb girth measurements (lymphedema surveillance)
• Pain score assessment (VAS/NRS)
• Wound healing status

---

Phase 3 — Progressive Strengthening Phase (Weeks 6–12)

• Restore rotator cuff and periscapular strength
• Normalize upper extremity strength symmetry
• Begin functional task training
• Aerobic fitness reconditioning

• Rotator cuff strengthening: internal/external rotation with resistance bands
• Serratus anterior activation: wall push-ups, protraction exercises
• Lower/middle trapezius strengthening: rows, prone Y/T/W exercises
• Progressive resistance training: light dumbbells, resistance bands
• Postural correction exercises: thoracic extension over foam roller
• Aerobic exercise: walking, stationary cycling — building to 150 min/week moderate intensity

• Monitor for axillary web syndrome ("cording") — tight bands in axilla with arm elevation
• Screen for signs of lymphedema before each session
• Avoid blood pressure cuffs and venipuncture on the affected arm

---

Phase 4 — Return to Function and Long-Term Maintenance (Months 3–12+)

• Full return to occupational and recreational activities
• Continued lymphedema management
• Psychological adaptation
• Cancer surveillance integration

• High-level resistance training progression
• Occupational task simulation
• Sports-specific training if applicable
• Ongoing lymphedema monitoring ± compression garment use
• Fatigue management strategies
• Bone health (osteoporosis risk with chemotherapy/hormonal therapy)
• Psychosocial support — support groups, counselling referral

---

3. ASSESSMENT OF SHOULDER DYSFUNCTION AFTER MASTECTOMY

Subjective Assessment

• Type and extent of surgery (total mastectomy, modified radical, radical, skin-sparing, nipple-sparing)
• Axillary intervention (SLNB vs. ALND — ALND carries significantly higher morbidity)
• Adjuvant therapy (radiation to axilla/chest wall worsens fibrosis; chemotherapy causes neuropathy)
• Pre-surgical shoulder function baseline
• Dominant hand status

• Pain (location, nature, severity — NRS 0–10)
• Stiffness and restricted movement
• Weakness (difficulty lifting, overhead tasks)
• Numbness or tingling (intercostobrachial nerve distribution — medial upper arm)
• Swelling (arm, hand, breast area)
• Tight bands/cords in axilla (axillary web syndrome)
• Sleep disturbance due to shoulder pain
• Psychological distress and fear of movement (kinesiophobia)

---

Objective Assessment

1. Posture and Observation

• Forward head, protracted shoulder, depressed affected shoulder
• Trunk lateral flexion toward affected side
• Scapular winging or tipping
• Breast asymmetry, chest wall deformity
• Skin color changes, visible swelling of upper extremity

---

2. Range of Motion Assessment

• Document the end feel (soft/firm/hard — fibrotic capsule vs. muscular guarding vs. bony block)
• Assess for painful arc (subacromial impingement pattern common post-surgery)

---

3. Muscle Strength Testing

• Manual Muscle Testing (MMT) — graded 0–5
• Key muscles assessed:
  • Serratus anterior (long thoracic nerve injury risk with ALND)
  • Trapezius (spinal accessory nerve at risk in extensive dissections)
  • Pectoralis major/minor (resected in radical mastectomy)
  • Deltoid, rotator cuff (secondary weakness from disuse/pain inhibition)
  • Latissimus dorsi (may be used in reconstruction flap)

---

4. Neurological Assessment

• Sensory testing: light touch, pin prick, vibration in dermatomal distributions
• Reflexes: biceps, triceps, brachioradialis
• Screen for radiation-induced brachial plexopathy if prior axillary radiation

---

5. Lymphedema Assessment

• Arm circumference measurements at standardized landmarks (olecranon, +10 cm, –10 cm, wrist)
• Bioimpedance spectroscopy (L-Dex) — gold standard for early subclinical detection
• Volume by water displacement
• Skin changes: pitting vs. non-pitting, fibrosis, skin texture changes
• Stemmer's sign (skin fold at base of finger — positive = lymphedema)
• International Society of Lymphology (ISL) Staging:

---

6. Axillary Web Syndrome (Cording) Assessment

• Palpate axilla and medial arm for fibrous cord-like structures
• Visible/palpable taut bands from axilla along medial arm to wrist
• Presents typically 2–8 weeks post-surgery
• Restricts shoulder flexion and elbow extension
• Assessed with shoulder flexion + elbow extension provocation test

4. MANAGEMENT OF SHOULDER DYSFUNCTION AFTER MASTECTOMY

A. Physiotherapy Interventions

Manual Therapy

• Glenohumeral joint mobilizations (Maitland Grades I–IV) for capsular restriction
• Scar tissue mobilization — transverse friction massage, instrument-assisted (IASTM)
• Myofascial release — pectoralis major/minor, anterior chest wall, cervical region
• Axillary web syndrome (cording) treatment:
  • Progressive shoulder abduction and elbow extension stretching
  • Direct cord mobilization/massage
  • Contract-relax techniques
  • Usually resolves within 3 months with treatment

Therapeutic Exercise (detailed in Phase 2–3 above)

1. Pendulum → AAROM → AROM → Resisted
2. Scapular stabilizers before global strength
3. Closed-chain before open-chain for pain control
4. Functional task integration

Electrophysical Agents

• TENS/IFC — pain management, allows participation in exercise
• LLLT (Low-Level Laser Therapy) — reduces post-mastectomy pain and improves ROM per some RCTs
• Ultrasound — scar tissue management (limited evidence, used adjunctively)
• Heat (moist heat packs) — pre-exercise muscle relaxation
• Cryotherapy — post-exercise inflammation control

B. Lymphedema Management

1. Manual Lymphatic Drainage (MLD) — specialized massage redirecting lymph to functional nodes
2. Multilayer compression bandaging — worn 23 hours/day in intensive phase
3. Decongestive exercise — limb movement within bandaging activates muscle pump
4. Skin care — prevent infection, maintain skin integrity
5. Compression garments — Class II (30–40 mmHg) for maintenance phase
6. Self-care education — self-MLD technique, garment management

C. Neuropathic Pain Management

• Post-mastectomy pain syndrome (PMPS) — chronic neuropathic pain in chest wall/axilla/arm
• Affects 20–50% of patients
• Management:
  • Desensitization techniques (graded tactile stimulation)
  • TENS over painful area
  • Pharmacotherapy (gabapentin, pregabalin, amitriptyline — in coordination with oncology team)
  • Mirror therapy / graded motor imagery for central sensitization

D. Winged Scapula (Serratus Anterior Palsy)

• Long thoracic nerve neuropraxia from ALND
• Conservative management is first-line (most resolve 6–24 months):
  • Scapular taping to prevent winging during exercise
  • Serratus anterior facilitation: wall push-ups, protraction in supine with resistance
  • Thoracic brace to unload scapula if severe
  • Avoid overhead loading until nerve recovery evident
• Surgical referral if no recovery by 24 months (nerve decompression, muscle transfer)

E. Postural Re-education

• Thoracic spine extension mobilization
• Cervical retraction exercises
• Chin tucks for forward head correction
• Proprioceptive neuromuscular facilitation (PNF) for trunk–shoulder coordination
• Mirror biofeedback for scapular alignment

F. Psychosocial Management

• Screen for depression/anxiety (PHQ-9, GAD-7)
• Refer for psychological support — cognitive behavioral therapy shown effective
• Body image therapy / peer support groups
• Graded exposure for kinesiophobia (fear-avoidance model)
• Fatigue management: energy conservation techniques, graded activity

G. Multidisciplinary Team (MDT) Integration

SUMMARY TABLE: Phase-by-Phase Overview

---

Clinical Pearl: The timing of drain removal is the critical gating event for shoulder rehab progression. Waiting for drain removal before initiating full shoulder ROM exercises reduces seroma risk without significantly compromising long-term outcomes. After drain removal, rapid progressive ROM work over the following 4–6 weeks is essential to prevent permanent restriction.

Red Flags requiring urgent referral: sudden increase in arm swelling (cellulitis/acute lymphedema), signs of brachial plexopathy, shoulder pain unresponsive to 6 weeks of physiotherapy (consider imaging to exclude axillary recurrence), or wound dehiscence/signs of infection.
