What is the post-operative rehabilitation protocol for a patient undergoing Mumford procedure (shoulder surgery)?

Mumford Procedure Post-Operative Rehabilitation Protocol

Immediate Post-Operative Phase (Day 1 - Week 2)

Begin rehabilitation immediately on postoperative day one with early mobilization and multimodal pain management, avoiding strict immobilization to optimize functional recovery and minimize complications. 1

• Start mobilization on postoperative day one regardless of the surgical procedure, as immediate activity without immobilization has been shown to be safe and effective for shoulder surgery 1, 2
• Apply cryotherapy during the first postoperative week to reduce pain (Level 1 evidence) 1
• Implement multimodal pain control strategies to facilitate early movement 1
• Remove drains, catheters, and lines as soon as safely possible to facilitate mobilization 3

Evidence Supporting Immediate Mobilization

The accelerated rehabilitation approach without immobilization following shoulder arthroplasty demonstrates non-inferiority with fewer postoperative complications, particularly related to falls, and provides psychological advantages with earlier return to function 2. This contrasts with traditional protocols requiring 3-6 weeks of immobilization, which show no superior outcomes 2.

Early Rehabilitation Phase (Weeks 2-6)

Progress to protected passive range of motion exercises while initiating isometric strengthening when pain-free. 1, 4

• Begin isometric quadriceps-equivalent exercises (isometric shoulder stabilizers) on postoperative day one when pain-free 1
• Introduce neuromuscular electrostimulation during weeks 2-8 to re-educate voluntary muscle contraction (Level 1 evidence) 1
• Combine neuromuscular training with early strength training throughout rehabilitation 1
• Progress passive range of motion gradually based on tissue healing and patient response 4

Active Rehabilitation Phase (Weeks 6-12)

Transition to active range of motion restoration and progressive strengthening beginning at postoperative week 12. 1, 4

• Restore full active range of motion before advancing to resistance training 4
• Implement structured, goal-based progression that prioritizes neuromuscular control 1
• Continue multimodal rehabilitation including cardiovascular, respiratory, and mobilization physiotherapy 3

Critical Timing Consideration

Postoperative rehabilitation started within the first 2 weeks reduces complications and hospital length of stay (Grade 2+ recommendation) 3. Delaying structured rehabilitation beyond 8 weeks may compromise medium- and long-term outcomes 3.

Advanced Strengthening Phase (Weeks 12+)

Continue structured rehabilitation for 9-12 months for patients returning to high-intensity activities or physically demanding work. 1

• Progress to sport-specific or work-specific functional training 1, 4
• Combine neuromuscular training with progressive strength training (Level 1 evidence) 1
• Use objective criteria rather than time alone to determine progression 1

Return-to-Activity Criteria

Do not base return to full activity on time alone; use objective functional criteria including no pain or swelling, full range of motion, and limb symmetry index >90% for strength testing. 1

• Minimum criteria include: no pain or swelling, full range of motion, limb symmetry index >90% for strength and functional tests, and completion of activity-specific training program 1
• Ensure patient demonstrates correct movement patterns without compensation 1

Common Pitfalls to Avoid

• Avoid prolonged immobilization (3-6 weeks in a sling), as this provides no superior outcomes and may increase complications 2
• Do not delay rehabilitation initiation beyond the first 2 weeks, as this compromises outcomes 3
• Avoid isolated single-modality therapy; multimodal rehabilitation combining cardiovascular, respiratory, and mobilization physiotherapy is superior to isolated techniques 3
• Do not progress based on time alone; use objective functional criteria to guide advancement 1

Rehabilitation Intensity and Monitoring

Follow the "10% rule" - increase activity intensity and duration by no more than 10% per week to prevent overload 5. Use pain or symptom provocation as the primary indicator to guide progression; if symptoms return during activity, reduce intensity until symptoms resolve 5.
