What is the recommended management for muscle strain?

Management of Muscle Strain

The mainstay of treatment for muscle strain is rest and limiting the use of the injured extremity, combined with cold application to decrease pain and swelling. 1

Initial Management (First 24-48 Hours)

RICE Protocol

• Rest: Avoid activities that cause pain and limit use of the injured muscle to prevent worsening the injury 1
• Ice: Apply cold therapy (ice and water surrounded by a damp cloth) to the injured area for 20-30 minutes, 3-4 times daily 1
  • Use a bag filled with ice and water surrounded by a damp cloth for maximum tissue cooling
  • Never place ice directly on skin to prevent cold injury
• Compression: Consider applying a compression wrap for comfort, especially for ankle strains 1
  • Ensure compression does not compromise circulation
• Elevation: Elevate the injured area when possible to reduce swelling

Pain Management

• Use acetaminophen rather than aspirin for pain relief, as aspirin affects blood coagulation 2
• NSAIDs may help reduce pain and inflammation in the acute phase 3

Rehabilitation Phase (After Acute Phase)

Progressive Activity

1. Begin with gentle range of motion exercises once acute pain subsides

2. Progress to light stretching exercises:

   • Hold stretches to the point of feeling tightness or slight discomfort 1
   • Hold static stretches for 10-30 seconds (30-60 seconds for older adults) 1
   • Repeat each stretch 2-4 times 1
   • Perform stretching when muscles are warmed through light activity or external methods like heat packs 1

3. Gradually introduce strengthening exercises:

   • Begin with 1-2 sets of 10-15 repetitions at light intensity (40-50% of maximum capacity) 1
   • Allow 48 hours rest between sessions for any single muscle group 1
   • Progressively increase resistance and/or repetitions as healing progresses 1

Return to Activity Guidelines

• Ensure full pain-free range of motion before returning to sports or strenuous activities
• Start with low-impact activities and gradually increase intensity
• Avoid excessive fatigue and perform adequate warm-up before intense exercise 3
• Monitor for signs of over-exercising:
  • Inability to finish activities with reserve
  • Difficulty breathing during exercise
  • Faintness or nausea after exercise
  • Chronic fatigue
  • Joint pain or stiffness 1

Common Pitfalls to Avoid

• Returning to activity too soon: This can lead to re-injury and prolonged recovery time
• Inadequate initial rest: Failing to rest the injured muscle can worsen the strain
• Improper ice application: Applying ice directly to skin or for too long can cause tissue damage
• Overly aggressive stretching: Stretching too aggressively or too early can exacerbate the injury
• Neglecting rehabilitation: Skipping the progressive strengthening phase increases risk of recurrence

Special Considerations

• For severe muscle strains with complete loss of function, surgical management may be required 4
• The optimal length of immobilization depends on the grade of injury and should not be longer than needed for adequate healing 4
• Early mobilization (after appropriate rest) is important to:
  • Promote proper orientation of regenerating muscle fibers
  • Improve revascularization
  • Minimize atrophy and loss of strength and flexibility 4

Most muscle strains have excellent outcomes with proper conservative management, and complications are relatively rare 3.
