Return From Injury / Rehab-to-Performance Continuum

This module covers general principles only — it is not a substitute for an individualized medical rehabilitation protocol. Specific injuries (e.g., ACL reconstruction, rotator-cuff repair, fracture) require diagnosis and a protocol from the treating physician/physiotherapist.

The rehab-to-performance continuum moves progressively from protected healing toward full sport/training capacity:

1. Protect & manage (acute): follow medical guidance; control pain/swelling; maintain unaffected fitness (e.g., train other body regions, low-impact cardio).
2. Restore range of motion, then basic strength and motor control with controlled, low loads.
3. Build capacity: progressive resistance and load tolerance (progressive-overload); restore strength symmetry.
4. Reintroduce speed, impact, plyometrics, and sport-specific demands as tissue tolerates.
5. Return to performance: full multidirectional, reactive, fatigued, and sport-specific work; meet return criteria.

Progress by criteria, not just time: advance when objective and symptom criteria are met — adequate ROM, strength (often limb symmetry index ~≥90% for return-to-sport in some protocols), control, and tolerance — rather than the calendar alone.

Pain/symptom monitoring (common guide): low-level pain during loaded rehab can be acceptable; a frequently cited rule is to stay within ≤2–3/10 pain that settles within ~24 hours and does not progressively worsen session to session. Escalating pain, swelling, or loss of function means regress and reassess.

General rules: start below capacity, change one variable at a time, manage total load and recovery (recovery-overview), individualize (individuality), and keep training the rest of the body to preserve fitness and morale.

• Work under the treating clinician/physiotherapist; obtain clearance before progressing through stages, especially post-surgery.
• Red flags to pause and seek care: significant new swelling, instability/giving way, locking, sharp worsening pain, numbness/tingling, signs of infection (post-surgical), or symptoms suggesting a new injury.

Educational only; not medical advice or a rehab protocol. Injury rehabilitation must be guided by the treating physician/physiotherapist; follow their individualized plan over any general statement here.

• Continuum: protect → restore ROM → strength/motor control → build capacity → impact/speed/sport-specific → return to performance.
• Progress by objective + symptom criteria (e.g., LSI ~≥90% in some protocols), not calendar alone.
• Pain guide: often ≤2–3/10, settling within ~24 h, not progressively worsening.
• Maintain unaffected fitness; start low, one variable at a time; individualize.
• Work with the treating clinician/PT; this is not a substitute for a medical protocol.

• progressive-overload — graded loading is the engine of rehab progression.
• postpartum — a specific staged-return application.
• low-back-pain — staged reconditioning for the spine.
• recovery-overview — managing total load during return.
