Pliability Training Rehabilitation Protocol (Sports Med)

Pathophysiology

Pliability, in the context of sports medicine, refers to the tissue's ability to deform easily under stress and return to its original shape when the stress is removed. Reduced pliability, often manifested as tightness, stiffness, or restricted range of motion (ROM), can stem from various sources, including:

• Muscle Imbalances: Agonist/antagonist strength discrepancies can lead to adaptive shortening of specific muscles.
• Adhesions and Scar Tissue: Following injury (e.g., muscle strain, ligament sprain), collagen deposition can restrict tissue glide and extensibility.
• Fascial Restrictions: The fascia, a connective tissue network throughout the body, can become thickened and less mobile due to inactivity, injury, or chronic stress.
• Neural Tension: Restricted nerve mobility can mimic or contribute to muscle tightness and pain. This may be related to adhesions around the nerve or increased sensitivity.
• Inflammation: Chronic inflammation can lead to fibrosis and reduced tissue elasticity.
• Inadequate Warm-up and Cool-down: Insufficient preparation for exercise and failure to address muscle recovery can increase the risk of stiffness and injury.
• Poor Posture: Sustained poor posture can place chronic stress on specific muscles and tissues, leading to adaptive shortening.
• Dehydration: Adequate hydration is essential for maintaining tissue lubrication and flexibility.

Impaired pliability can contribute to altered movement patterns, increased risk of injury (muscle strains, tendonitis, joint pain), decreased athletic performance, and chronic pain syndromes. This protocol outlines a structured rehabilitation program to restore and improve tissue pliability, reduce pain, and optimize function.

Assessment

Prior to initiating the rehabilitation program, a thorough assessment is crucial. This should include:

• Subjective History: Gather information regarding the patient's symptoms, injury mechanism (if applicable), activity level, and goals.
• Observation: Assess posture, gait, and movement patterns for any asymmetries or compensatory strategies.
• Palpation: Identify areas of tenderness, muscle spasm, trigger points, and fascial restrictions.
• Range of Motion (ROM) Assessment: Measure active and passive ROM in affected joints and compare to contralateral side.
• Strength Testing: Assess muscle strength in relevant muscle groups.
• Neurological Examination: Rule out any neurological involvement (e.g., nerve root compression).
• Special Tests: See section below for common special tests.

Phase I: Protection (Acute Phase - Days 1-7, or until pain subsides)

Goals: Reduce pain and inflammation, protect injured tissues, minimize further damage, and initiate gentle ROM exercises.

• Pain Management:
• Relative Rest: Avoid activities that aggravate symptoms.
• Ice: Apply ice packs for 15-20 minutes, several times a day.
• Modalities: Consider using modalities such as electrical stimulation (TENS) or ultrasound for pain relief.
• Gentle Massage: Light effleurage massage to reduce muscle spasm and promote circulation.
• Gentle Range of Motion (ROM):
• Active Assisted ROM (AAROM): Perform gentle ROM exercises within pain-free limits, using assistance from the therapist or unaffected limb.
• Passive ROM (PROM): Therapist-assisted ROM exercises to maintain joint mobility.
• Isometric Exercises: Perform gentle isometric contractions of surrounding muscles to maintain strength without stressing the injured tissues.
• Education: Educate the patient about their condition, the importance of adherence to the rehabilitation program, and proper body mechanics.

Phase II: Loading (Subacute Phase - Weeks 1-4, or until ROM and pain significantly improve)

Goals: Restore full ROM, improve muscle strength and endurance, and begin functional activities.

• Progressive ROM Exercises:
• Active ROM (AROM): Progress from AAROM to AROM as tolerated.
• Static Stretching: Hold stretches for 30-60 seconds to improve muscle length. Focus on major muscle groups identified as tight during assessment.
• Dynamic Stretching: Incorporate dynamic stretches to improve flexibility and prepare muscles for activity.
• Strengthening Exercises:
• Progressive Resistance Exercises (PRE): Gradually increase resistance using weights, resistance bands, or body weight. Focus on strengthening both agonist and antagonist muscles.
• Endurance Exercises: Incorporate exercises with high repetitions and low resistance to improve muscle endurance.
• Core Stabilization Exercises: Strengthen core muscles to improve stability and control.
• Manual Therapy:
• Soft Tissue Mobilization (STM): Address fascial restrictions, muscle adhesions, and trigger points using techniques such as myofascial release, trigger point release, and cross-friction massage.
• Joint Mobilization: Address any joint restrictions using appropriate mobilization techniques.
• Neural Mobilization: Address any neural tension using gentle nerve gliding techniques.
• Proprioceptive Exercises: Incorporate exercises to improve balance and coordination, such as single-leg stance, wobble board exercises, and balance beam walking.

Phase III: Return to Function (Weeks 4+, or until full pain-free ROM, strength and stability are achieved)

Goals: Restore full functional capacity, prevent re-injury, and return to sport or desired activity level.

• Advanced Strengthening Exercises:
• Plyometric Exercises: Introduce plyometric exercises to improve power and explosiveness.
• Sport-Specific Exercises: Incorporate exercises that mimic the demands of the patient's sport or activity.
• Agility and Coordination Exercises: Improve agility and coordination with cone drills, shuttle runs, and other sport-specific drills.
• Functional Training: Simulate real-world activities to prepare the patient for a return to function.
• Maintenance Program: Develop a home exercise program to maintain pliability, strength, and prevent re-injury. This should include regular stretching, strengthening, and self-myofascial release techniques.
• Gradual Return to Activity: Gradually increase activity level as tolerated, monitoring for any signs of re-injury.
• Education: Reinforce proper body mechanics, warm-up and cool-down routines, and injury prevention strategies.

• Straight Leg Raise (SLR): Sciatic nerve irritation or lumbar disc herniation.
• Piriformis Test: Piriformis syndrome.
• Shoulder Impingement Tests (Neer's, Hawkins-Kennedy): Shoulder impingement.
• Anterior Drawer Test (Ankle/Knee): Ligamentous laxity (ATFL/ACL).
• Posterior Drawer Test (Ankle/Knee): Ligamentous laxity (PTFL/PCL).
