As the number of "yes" answers increases, so does the indication to use** cold. **Developing a Rehabilitation Program.** **Understanding the healing process** - **[SAID principle]** - *[Specific adaptations for imposed demands]* - When an injured structure is subjected to stresses and overloads of varying intensities, it will gradually adapt over time to whatever demands are placed upon it. - Too little stress no progress - Too much stress increased chance of injury - May result in inflammation, pain, loss of ROM, increase in laxity of ligaments. - Early rehab involves submaximal exercise performed in short bouts several times a day. - Exercise intensity will increase as the healing process progresses. - Exercises will then be performed less often - Conditioning mode will follow which may include high intensity exercises 3-4 times per week. **Goals of a rehabilitation program -- Identified and Adjusted daily based on progress or regress** I. **To control [swelling]** A. Through immediate first aid management B. When swelling occurs 1. It is caused by several factors a. Bleeding b. Production of synovial fluid c. Accumulation of inflammatory by-products d. Edema 2. Causes an increased pressure in the area e. This pressure results in an increase in pain 3. Causes neuromuscular inhibition f. Results in weak muscle contractions 4. Swelling occurs most likely 72 hours post injury 5. It will inhibit the healing process 6. By controlling the acute injury stage the rehabilitation may be 7. **PRICE** helps to control swelling g. **Protection** 1. Splints 2. Pads 3. Immobilization devices 4. Crutches h. **Restricted activity (rest)** 5. Will vary depending on severity of injury a. Most minor injuries 24-48 hours before rehab begins 6. If not rested the injured area will be subjected to 7. It does not mean no mobility or that the athlete does nothing. 8. Controlled mobility is superior to immobilization in b. Scar formation c. Revascularization d. Muscle regeneration e. Reorientation of muscle fibers and tensile properties i. **Ice** 9. Used for controlling metabolism f. Secondary cell hypoxia 10. Used to decrease pain 11. Used for vasoconstriction g. Controls hemorrhaging 12. Reduces muscle guarding and spasms 13. It will decrease nerve conduction velocity h. This helps with pain control 14. Pain sensations include i. Uncomfortable sensation of cold -- pain j. Burning k. Aching l. Numbness j. **Compression** 15. Single most important technique for controlling initial 16. Purpose to mechanically reduce the amount of space for 17. Best application is with an Ace wrap m. Apply firm but evenly 18. Pressure can build causing pain 19. Wrap should be kept in place despite the pain to control the swelling n. Make sure there is no circulatory problems and 20. In cases of tendonitis, bursitis, tenosynovitis, the k. **Elevation** 21. Eliminates the effects of blood pooling due to gravity 22. Assists in venous and lymphatic drainage 23. Greater the degree of elevation the greater the effect in II. **Control [Pain]** C. Is determined by 8. Extent of injury 9. Athlete's response and perception of pain 10. Circumstances in which injury occurred l. Why and how should 2&3 affect injury D. Can modulate pain by using PRICE immediately after injury E. Medications F. Pain will inhibit strengthening and flexibility exercises G. Pain will dictate rate of progress H. Pain, swelling or other symptoms after exercise or activity will indicate that III. **Restore [ROM]** I. May be caused from: 11. Muscle, tendon, fascia inability to stretch 12. Connective tissue contractures (joint capsule, lig) 13. Combination of both J. Need to incorporate stretching exercises K. Possible joint mobilization or traction may be necessary IV. **Restore [muscle strength, endurance & power]** L. **Isometric** 14. Early phases of rehab 15. Muscle contracts but neither shortens nor lengthens M. **Isotonic or Progressive Resistive Exercise (PRE's)** 16. Most commonly used strengthening tech 17. Free weight, theraband, exercise machines 18. Fixed resistance with accomadating speed 19. May be either eccentric or concentric m. Concentric the muscle contracts and shortens n. Eccentric the muscle contract while it lengthens. N. **Isokinetic** 20. Used during later phases of rehab 21. Fixed speed with accomodating resistance 22. May use either eccentric or concentric 23. Used commonly for return to play criteria V. **Reestablish [neuromuscular control]** O. Should be a prime concern P. Position of joint space is mediated by mechanoreceptors found in muscles and Q. Neuromuscular control relies on CNS 24. To interpret and integrate proprioceptive and kinesthetic info o. This helps to control individual muscles and joints p. Coordinates movements R. Nervous system tends to forget how to put info together S. Regaining NM control means reestablishing previous sensory patterns T. It is the minds attempt to teach the body conscious control of a specific U. Repetition makes progression less difficult, less concentration more V. Is a step by step process W. Closed kinetic chain exercises are essential for NMC X. Is critical throughout rehab but is most critical during early stages VI. **Reestablish [balance]** Y. Involves complex integration of muscular forces, neurological senses, Z. Proprioceptive training is key to prevent further injuries **VII [Cardiorespiratory fitness]** A. Single most neglected component B. Will decrease rapidly 25. ½ hearbeat per day of immobilization C. Difficult to balance rehab and conditioning due to 26. Pain 27. Psychological issues (depression, ect) 28. Boring 29. Difficult to see immediate benefits D. Pool activities are excellent for maintaining CRF E. Cycling is also beneficial **VIII Functional progression** A. Includes gradual progressive activities 1. Broken down into component parts 2. Monitored carfully a. Pain and swelling are guidelines 3. Helps to achieve normal ROM, strength, neuromuscular control **IX Functional testing** B. Used to determine how close an athlete is to returning to competition C. Figure eights, shuttle run, vertical jump Remember - Stable to Unstable / Static to Dynamic \*\*\* when trying to make an exercise easier or harder. **Criteria for increasing physical demands (from weightbearing to full participation)** 1. - 2. - 3. - 4. - 5. - 6. - 7. - 8. - 9. - 10. - 11. - 12. - 13. - 14. - TENDONITIS Causes - Increasing too fast, too much, too hard, too many reps - Rule of thumb -- 10-15% increments per week is safe - Tennis player hitting a backhand late -- lateral epicondylitis - Improper weight-lifting - Pronation while running - Weak rotator cuff -- leads to humerus instability and possible impingement - Tendons prone to reduced circulation - Achilles tendon - Supraspinatus - Areas where tendon is compressed against the bone or retinacular tendons - Biceps tendon -- transverse lig holds the tendon in bicipital - Groove Basic Treatment for tendonitis A.
