Chapter 16 Extended Lecture Outline The Athletic Trainers Approach to Rehabilitation o Process of rehabilitation begins immediately after injury o Competitive nature of athletics necessitates an aggressive approach to rehabilitation o Goal is for the athlete to return to activity as soon as safely possible o Decisions to alter and advance programs should be based within the framework of the healing process o The use of rehabilitation recipes is discouraged, each person is different Therapeutic Exercise Versus Conditioning Exercise Sudden Physical Inactivity and Injury Immobilization o Effects of General Inactivity o Effects of Immobilization Muscle and Immobilization o Adverse muscle changes can occur in 24 hours Atrophy and fiber-type conversion o Disuse leads to loss of muscle mass o Greatest atrophy occurs in Type I (slow-twitch) fibers o When activity is resumed, normal protein synthesis is reestablished Decreased neuromuscular efficiency o Immobilization causes motor nerves to become less efficient in recruiting and stimulating individual muscle fibers o Once immobilization ends – original motor discharge returns in about 1 week Joints and Immobilization Causes loss of normal compression, leading to decrease in lubrication within the joint causing degeneration Ligament and Bone and Immobilization Ligament and bone become weaker when stress is eliminated or decreased Full remodeling of ligaments after immobilization may take as long as twelve months or more Cardiorespiratory System and Immobilization Resting heart rate increases approximately one-half beat per minute each day of immobilization Stroke volume, max oxygen uptake and vital capacity decrease Major Components of a Rehabilitation Program o Minimizing Initial Swelling o Controlling Pain o Reestablishing Neuromuscular Control Neuromuscular control: the mind’s attempt to teach the body conscious control of a specific movement Four critical elements: proprioceptive and kinesthetic awareness, dynamic stability, preparatory and reactive muscle characteristics, and conscious and unconscious functional motor patterns Proprioception: the ability to determine the position of a joint in space Kinesthesia: the ability to detect movement Ability to sense the position of a joint in space is mediated by mechanoreceptors found in both muscle and joints and by cutaneous, visual and vestibular input Joint Mechanoreceptors Ruffini’s corpuscles Pacinian corpuscles Merkel’s corpuscles Meissner’s corpuscles Free nerve endings Muscle Mechanoreceptors Muscle spindles and golgi tendon organs o Establishing and Enhancing Core Stability Core is defined as the lumbo-pelvic-hip complex, where the center of gravity is and where all movement begins Key muscles include transversospinalis group, erector spinae, quadratus lumborum and latissimus dorsi, rectus abdominus, external oblique, internal oblique and transverse abdominus, gluteus maximus, gluteus medius and psoas o Regaining or Improving Range of Motion Physiological versus Accessory Movements Physiological movements result from an active muscle contraction that moves an extremity through flexion, extension, abduction, adduction and rotation Accessory motions refer to the manner in which one articulating joint surface moves relative to another (spin, roll and glide) Normal accessory motions must occur for full-range physiological movement to take place If physiological movements are restricted – one should engage in stretching activities to improve flexibility If accessory motions are restricted – incorporate mobilization techniques into treatment program o Restoring or Increasing Muscular Strength and Endurance Isometric Exercise Progressive Resistance Exercise Concentric and eccentric muscle contraction Isokinetic Exercise Testing Strength, Endurance and Power o Regaining Balance and Postural Control Balance involves the complex integration of muscular forces, neurological sensory information received from the mechanoreceptors, and biomechanical information Achieving postural stability involves positioning the body’s center of gravity within the base of support Primary mechanisms for controlling postural stability occur in the joints of the lower extremity o Maintaining Cardiorespiratory Fitness o Incorporating Functional Progressions Functional Testing Developing a Rehabilitation Plan o Setting Long-term and Short-term Goals o Exercise Phases Preoperative Exercise Phase Phase 1: The acute inflammatory response phase o Begins immediately and may last as long as 4 days o Focus of rehab is to control swelling and to modulate pain by using rest, ice, compression, and elevation Phase 2: The fibroblastic repair phase o This stage may begin as early as four days after injury and may last for several weeks o Incorporate activities to maintain cardiorespiratory fitness, restore full range of motion, restore or increase strength and reestablish neuromuscular control o Modalities to control pain and swelling and improve strength/range of motion Phase 3: The maturation-remodeling phase o o May last for several years, depending upon the severity of the injury Ultimate goal of this stage is to return to activity – focus should be on regaining sport-specific skills o Adherence to a Rehabilitative Program o Criteria for Full Return to Activity Additional Approaches to Therapeutic Exercise in Rehabilitation o Open Versus Closed Kinetic Chain Exercises CKC exercises have become rehab treatment of choice because they are more functional than open chain exercises CKC exercises use varying combinations of isometric, concentric, and eccentric contractions which must occur simultaneously in different muscle groups o Aquatic Exercise Three uses of water’s buoyancy (Assistive, supportive and resistive) o Proprioceptive Neuromuscular Facilitation Techniques Techniques of PNF Used for purposes of facilitating strength and increasing range of motion Flexibility increased with contract-relax, hold-relax, and slow-reversal-holdrelax Strengthening can be facilitated by repeated contraction and the slow-reversal, rhythmic initiation and rhythmic stabilization techniques Strengthening Techniques Rhythmic initiation Repeated contraction Slow reversal Slow-reversal-hold Rhythmic stabilization Stretching Techniques Contract-relax Hold-relax Slow-reversal-hold-relax Basic Principles for Using PNF Techniques PNF Patterns Involve three component movements: flexion-extension, abduction-adduction and internal-external rotation Involve distinct diagonal and rotational movements Exercise patterns are initiated with muscle groups in lengthened or stretched positions o Muscle Energy Techniques Manually applied stretching techniques that use principles of neurophysiology to relax overactive muscles and/or stretch chronically shortened muscles Manual therapy technique that is variation of PNF contract-relax, and hold-relax techniques Technique begins by locating a point of resistance to stretch (resistance barrier) o Joint Mobilization and Traction Mobilization Techniques Used to increase accessory motions about a joint by use of glides within a specific part of the range of motion Maitland – Five grades o Grade I – Small amplitude at beginning ROM o Grade II – Large amplitude glide within the midrange of motion o Grade III – Large amplitude glide up to the pathological limit of ROM o Grade IV – Small amplitude glide at end range of movement o Grade V – Small amplitude, quick thrust delivered at the end range of motion (manipulation) Traction: Technique in which one articulating segment is pulled to produce some separation of the two joint surfaces o Mulligan Technique Combines passive accessory joint mobilization applied with an active physiological movement by the patient for the purpose of correcting positional faults and returning the patient to normal pain-free function Mobilizations with movement (MWM’s) for treating extremities, and sustained natural apophyseal glides (SNAG’s) for treating the spine Principles of treatment o Myofascial Release Group of techniques used for the purpose of relieving soft tissue from the abnormal grip of tight fascia – form of stretching Myofascial treatment based on localizing the restriction and moving into the direction of the restriction o Graston Technique o Strain/Counterstrain Approach to decreasing muscle tension and guarding that may be used to normalize muscle function Passive technique that places the body in a position of greatest comfort , thereby relieving pain Explained by stretch reflex o Positional Release Therapy Based on strain/counterstrain techniques – primary difference is the use of facilitating force (compression) to enhance the effect of the positioning Active Release Technique Developed to correct soft tissue problems in muscle, tendon, and fascia caused by the formation of fibrotic adhesions as a result of acute injury, repetitive or overuse injuries or constant pressure or tension injuries Fibrotic adhesions disrupt the normal muscle function, which affects the biomechanics of the joint – leading to pain and dysfunction Deep tissue technique used for breaking down scar tissue/adhesions and restoring function and movement o Soft-Tissue Mobilization o Biofeedback Used as a tool to help a patient develop greater voluntary control for purpose of enhancing either neuromuscular relaxation or muscle reeducation following injury Purchasing and Maintaining Therapeutic Exercise Equipment
