Phases of Rehabilitation and Advanced Techniques:-
- Phase 1: Acute/Protection Phase (Typically 0-7 days)
- Goals: Reduce pain, control swelling, protect the injured tissue, and prevent further damage.
- Interventions:
- POLICE Protocol: Protection (e.g., crutches, sling, brace to offload the injured muscle), Optimal Loading (early, pain-free movement to promote healing without re-injury), Ice (cryotherapy to reduce inflammation and pain), Compression (elastic bandage to minimize swelling), Elevation (to reduce swelling).
- Gentle Passive/Active-Assisted Range of Motion (ROM): Moving the affected limb through pain-free ranges to prevent stiffness and promote fluid circulation.
- Isometric Exercises: Very gentle muscle contractions without movement (e.g., holding a contraction against resistance without joint movement) to maintain muscle activation and prevent atrophy, without stressing the healing fibers.
- Electrotherapy: Modalities like TENS (Transcutaneous Electrical Nerve Stimulation) for pain relief, or Low-Level Laser Therapy (LLLT) to stimulate cellular healing.
- Phase 2: Subacute/Repair Phase (Typically 1-4 weeks)
- Goals: Restore full pain-free range of motion, begin gentle strengthening, promote scar tissue remodeling.
- Interventions:
Progressive Active Range of Motion (AROM) and Stretching: Gradually increasing the range of movement, incorporating gentle static and dynamic stretches for the injured muscle and surrounding joints.
- Light Resistance Exercises:
- Isotonic Exercises: Controlled movements with light resistance (e.g., bodyweight exercises, light resistance bands). Focus on full, pain-free range.
- Eccentric Loading (Gentle): Introducing very controlled eccentric contractions (muscle lengthening under load) at low intensity. This is crucial for scar tissue alignment and strength but must be carefully monitored.
- Manual Therapy:
- Soft Tissue Mobilization/Deep Transverse Friction Massage: Once the initial acute pain subsides, specific massage techniques applied directly to the healing site to break down adhesions, promote collagen alignment in the scar tissue, improve blood flow, and reduce pain.
- Myofascial Release: Techniques to release tightness in the fascia surrounding the injured muscle and compensatory muscle groups.
- Dry Needling: Highly effective for persistent muscle tightness or trigger points that often accompany muscle strains. Insertion of thin needles into hyperirritable muscle bands (“knots”) helps to elicit a “local twitch response,” reducing muscle tension, pain, and improving blood flow. This technique helps to “reset” dysfunctional muscle fibers.
- Therapeutic Taping (Kinesiology Taping): Can be used to:
- Reduce Swelling: By lifting the skin and facilitating lymphatic drainage.
- Provide Support and Stability: Without restricting movement.
- Facilitate Muscle Activation: By providing proprioceptive feedback to weakened muscles.
- Inhibit Overactive Muscles: To reduce tension in compensatory muscles.
- Phase 3: Remodeling/Strength and Endurance Phase (Typically 4-12 weeks)
- Goals: Maximize strength, endurance, power, and neuromuscular control; prepare for functional activities.
- Interventions:
- Progressive Resistance Training: Increasing intensity, repetitions, and type of resistance (free weights, machines).
- Eccentric Strengthening: More advanced eccentric exercises, as they are key for building resilience and preventing re-injury (e.g., controlled lowering phases in squats, lunges, hamstring curls).
- Plyometric Exercises: (For Grade II/III, once strength is adequate) Controlled jumping, hopping, and bounding drills to improve power and shock absorption, gradually introduced.
- Proprioception and Balance Training: Exercises on unstable surfaces (wobble boards, foam pads) to improve joint position sense and dynamic stability, reducing re-injury risk.
- Functional Training: Mimicking sport-specific or daily activity movements (e.g., cutting drills, agility drills, lifting techniques).
- Manual Therapy (continued): As needed for ongoing stiffness, scar tissue restrictions, or trigger points.
- Phase 4: Return to Sport/Activity Phase (Highly variable, 12+ weeks for severe strains)
- Goals: Gradual and safe return to full activity levels without re-injury.
- Interventions:
- Sport-Specific Drills: Progressing from low-intensity to high-intensity drills that replicate the demands of the sport (e.g., accelerating, decelerating, pivoting, throwing).
- Graded Exposure: Gradually increasing the duration, intensity, and complexity of activity.
- Warm-up and Cool-down Education: Emphasizing proper routines.
- Prevention Strategies: Education on strength maintenance, flexibility, proper biomechanics, and recognizing signs of fatigue.
- Rigid Taping/Bracing: May be used for temporary support and confidence during the initial return to high-demand activities.
