Req 8b — Strains, Tears & Tendon Injuries
In Req 8a, you learned the difference between a strain, a muscle tear, and a tendon rupture. Now you’ll focus on the specific symptoms and first aid for each. Note that the management of soft tissue injuries follows a consistent framework — the differences are mainly in severity and what to do about returning to activity.
First Aid Framework: RICE
For strains and mild muscle tears, the foundational first aid is RICE:
- Rest — stop the activity causing pain; protect from further injury
- Ice — apply ice or cold pack (wrapped in cloth) 20 minutes on, 20 minutes off, for the first 24–48 hours
- Compress — a light elastic bandage reduces swelling
- Elevate — raise the injured area above heart level when possible
Some guidelines now use POLICE (Protection, Optimal Loading, Ice, Compression, Elevation) to emphasize that some gentle movement during recovery promotes healing — but rest is still appropriate in the acute phase (first 24–48 hours).

Muscle Strain
Symptoms and signs:
- Muscle pain that intensifies with use or stretching
- Mild to moderate swelling
- Stiffness — the muscle feels tight or knotted
- Possible bruising appearing 24–48 hours after injury
- Weakness of the involved muscle group
- Movement is painful but the muscle still functions
Grades:
- Grade I: Mild — minor fiber tearing, minimal strength loss
- Grade II: Moderate — partial tearing, noticeable strength loss
- Grade III: Severe — nearly complete rupture (transitioning into “muscle tear”)
First aid:
- Apply RICE (see above).
- For Grade I–II strains: the Scout may be able to continue a hike with modified pace; monitor for worsening.
- For Grade III: treat as a muscle tear (see below).
- Over-the-counter pain relievers (ibuprofen/naproxen) help with both pain and inflammation.
- Return to activity only when pain-free — premature return worsens the injury.
Muscle Tear (Complete Rupture)
Symptoms and signs:
- A sudden, intense pain during activity — often described as being “hit” or “shot” in the muscle
- A pop or snap may be felt or heard
- Rapid onset of swelling and bruising (blood pooling from the tear)
- A visible or palpable “dent” or “gap” where the torn muscle has retracted
- Significant loss of strength — the affected muscle group may be nearly nonfunctional
First aid:
- Immobilize and support the injured extremity.
- Apply ice to limit swelling.
- Do NOT massage or try to “stretch out” the injury.
- Evacuate if in the wilderness — complete muscle tears typically require orthopedic evaluation and potentially surgery.
- Keep the person from using the affected limb.
Tendon Rupture
Symptoms and signs:
- A sudden, severe pain at the tendon location (Achilles tendon: back of the heel; patellar tendon: front of the knee; biceps tendon: front of the shoulder/elbow)
- A “pop” or “snap” at the moment of injury
- Rapid swelling
- A palpable gap in the tendon
- Inability to perform the function of the muscle attached to that tendon: can’t push off the foot (Achilles), can’t fully straighten the knee (patellar/quad), can’t flex the elbow against resistance (biceps)
First aid:
- Immobilize the joint in a neutral position; do not allow weight-bearing on an Achilles or knee tendon rupture.
- Apply ice to limit swelling and pain.
- Transport/evacuate for medical care — complete tendon ruptures almost always require surgical repair for full functional recovery.

Now you know the soft tissue injuries. Next, you’ll learn about joint injuries (sprains and dislocations) and bone fractures.
