Therapeutic Modalities and Injury Rehabilitation Unit 7 Therapeutic Modalities Create optimum environment for injury healing Reducing pain and discomfort Many different modalities to choose from Selection of Specific Treatment is dependant on: Injury site, type and severity Modality indication and contraindication Physician prescription Athlete willingness to accept treatment More is not better Misuse or overuse of a modality can: Aggravate the condition Delay the athlete’s return to play Legal Concerns Must be administered in accordance with local regulations Documentations of all treatments Types of Modalities Cryotherapy Ice packs, ice massage, whirlpool, immersion, sprays Thermotherapy Moist heat packs, whirlpool, paraffin, ultrasound, phonophoresis Contrast Electrotherapy Iontophoresis Mechanical Massage, manipulation Cryotherapy Cold application 15-20 minutes every 11/2 waking hours- along with rest, compression, and elevation Reduces many adverse conditions related to inflammatory phase Physical and Physiological Effects of Cold PHYSICAL Conduction- when a cold object is applied to a warmer object, heat is abstracted The longer cold exposure is the deeper the cooling is. Tissue that has previously been cooled takes longer to return to normal temperature than tissue that has been heated Dept of cold penetration can reach up to 5 cm PHYSIOLOGICAL Decrease in tissue temp Decrease in blood flow Vasoconstriction Decrease in muscle spasms Decrease in pain perception Decrease muscle fatigue Decrease metabolic rate Decrease waste products in area that act as muscle irritant Increase collagen inelasticity and joint stiffness Increase capillary permeability Special Considerations Indications Acute sprains, strains, contusions, spasms, inflammation Contraindications Circulatory disturbances, hypersensitivity, prolonged application over superficial nerves Allergic React with hives, joint pain and swelling Continued on next slide… Special Considerations Cont… Raynaud’s Phenomenon Condition that causes vasospasm of digital arteries lasting min-hours Can lead to tissue death Ice should never be applied for longer than 20-30 minutes Hunting Response Occurs when cold is applied for longer than 30 minutes intermittently Vasodilation occurs for 4-6 minutes Reaction against tissue damage from too much cold Stages of Cryotherapy 0-3 minutes after initiation feel cold sensation 2-7 minutes after initiation feel mild burning, aching 5-12 minutes after initiation feel numbness, anesthesia Cryotherapeutic Methods Ice Packs Flaked or crushed ice in a towel or plastic bag Apply for 15-20 minutes combined with RICE Ice Massage Paper cup filled with frozen water to from an ice cylinder Rub or massage directly over area until skin becomes bright pinkusually for 7-10 min Cold Water Immersion Whirlpool, bucket or container filled with mixture of water and icetemp- 55-65 degrees F Immersion for 10-20 minutes- great for hands, feet and ankles Vapocoolant Sprays cold spray of chemicals sprayed of surface of skin to freeze it Treat myofascial pain and trigger point, usually combined with stretching. Effects are superficial and temporary Thermotherapy Used of sub-acute injuries Used to increase blood flow Promotes healing in the injured area Vasodilation occurs to shunt cooler blood to warmed area Do not use until active inflammatory process is over/ no signs of swelling Conduction Occurs when heat is transferred from a warmer object to a cooler one Heat should never exceed 116 degrees F Examples are moist heat packs, paraffin baths, and electric heating pads Physical Principles of Heat Conduction Convection Radiation Conversion Convection Refers to the transference of heat through the movement of fluids or gases Factors that influence convection heating are temperature, speed of movement and the conductivity of the part Example: whirlpool bath Radiation The process whereby heat energy is transmitted through empty space Heat is transferred from one object through space to another object Examples: Infrared heating and ultraviolet therapies Conversion Refers to the generation of heat from another energy form such as sound, electricity and chemical agents Examples: Ultrasound therapy, diathermy, chemical agents- balms Physiological Effects of Heat Body’s response to heat depends on Type of heat energy, duration, intensity, tissue type Decrease muscle spasm Decrease pain perception Increased blood flow Increase metabolic rate Decreased joint stiffness Increase range of motion Increasing the extensibility of collagen tissue Increased general relaxation Special Considerations Reasonably safe- as long as heat is at safe intensity and application is not for too long Contraindications: An area of loss of loss of sensation Immediately after an injury An area where there is decreased arterial circulation Eyes and genitals Abdomen during pregnancy To a malignancy Monitor heat when applied to elderly patients or infant Thermotherapy Methods Moist Heat Packs Whirlpool Bath Contrast Bath Paraffin Bath Ultrasound Therapy Phonophoresis Moist Heat Packs Commercial Packs- Hydrocollator Packs Silicate gel in a cotton pad immersed in 170 degrees of hot water Apply 15-20 minutes Layers of towels are used between packs and the skin to avoid burning. As packs cool remove towels Deep tissues are not significantly heated Inhibited by subcutaneous fat acts as insulator Patient should be in comfortable position Patients should not lie on the hot pack because heat can not dissipate out Whirlpool Bath Tank with a turbine motor which regulates the movement of water and air Cold- 55 degrees F, Neutral- 92-96 degrees F, Warm- 96-98 degree F and Hot 98-104 degrees F Convection and Conduction are occurring Reduces swelling, muscle spasm and pain and active movement is also assisted Whirlpool Continued Treatment time should not exceed 20 minutes Whirlpool unit/tank must be kept clean Frequent water changes and daily cleaning essential Open wounds and abrasions should be handled cautiously so that contamination or spreading of the infection is prevented Contrast Baths One unit holding hot water at 105-110 degrees F ( for example a whirlpool) One unit holding cold water at 50-65 degrees F ( for example a bucket can be used) The goal to alternating hot and cold is to increase local circulation to the treated limb Vasodilation from hot water and Vasoconstriction from the cold water accomplishes this Contrast Baths Continued The limb is first placed in the warm water for 5 minutes Then is alternated to the cold water for 1 minute Hot to cold is 1 cycle, after first cycle use 4 minutes in hot and 1 minute in cold Repeat 4/1 cycle for up to 30 minutes Paraffin Baths Paraffin and mineral oil that is kept at 125-130 degrees F in a controlled unit Provide superficial heat to angular, bony areas of the body (hands, feet, wrists) Allows the part to remain elevated Sustains heat which increases circulation and decreases pain in affected area Before treatment clean and dry area to be treated thoroughly Paraffin Bath Continued Dip the affected part into the paraffin bath and quickly pull it out Allow the accumulated wax to dry and form a solid covering This process of dipping and withdrawing is repeated until the wax coating is 1/4 to 1/2 inch thick Ultrasound Therapy Ultrasound uses high frequency sound waves Sound energy causes molecules in the tissues to vibrate, thus producing heat and mechanical energy 1mHz is the frequency used when heating is needed for deep tissue 3mHz is the frequency used when heating is needed for areas with minimal soft tissue coverage Nerve tissue is twice as sensitive to ultrasound than muscles Ultrasound Therapy Thermal and mechanical effects of ultrasound increase circulation and promote healing Ultrasound raises tissue temperature 7-8 degrees F up to 2 inches below the skin’s surface Little or no change in skin temperature Also provides a micro massaging action on cells Pulsed and Continuous Waves Pulsed Non thermal effect The flow of sound waves are interrupted, thus less energy is produced Best used on Sub acute injuries Wound healing Over bony areas Continuous Thermal effects Sound waves are continuous Increase circulation Non thermal effects At a low intensity Acute injuries Indications for Ultrasound Post acute soft tissue trauma Bursitis Tendonitis Fascitis Contraindications for Ultrasound Acute inflammatory conditions with continuous mode Over areas with limited vascularity or sensation Over eyes, ear, heart, reproductive organs, endocrine glands, CNS or open epiphysis (growth plates!!!) More info on Ultrasound There must be a coupling medium Acoustic energy can not travel through air, is reflected by skin Lotion, gel, water applied to the skin Transducer (sound head) should be kept moving at all times Small circles or longitudinal strokes at speed 1-2 inches per second More info on Ultrasound Treatment is 5 minutes for an area 3-4 times of the sound head Intensity Determined by the stage of injury and depth of target tissue Underwater application Good for bony areas like hand, wrist and feet Hold sound head 1 inch from body part and move in circular or longitudinal patterns Phonophoresis Method of driving molecules through the skin by ion transfer – by the mechanical vibration of the ultrasound Designed to move an entire molecule of medication into injured tissues Hydrocortisone and and anesthetic are used with success Massage medication into the skin over area, then spread the coupling agent, then ultrasound Lower intensity for a longer duration Tendonitis, bursitis and painful trigger points Electrotherapy Purpose Control pain Exercise muscle tissue to decrease atrophy Encourage circulation Increase tissue temperature Encourage breakdown of adhesions Reeducate muscles Physical Principles of Electrotherapy Electricity is a form of energy that displays the following factors on tissue: Magnetic Chemical Mechanical Thermal Effects Electrotherapy Currents Produce waveforms Waveforms refer to the shape, direction, amplitude and duration of electric current Direct Current Flows in one direction Electrons move from a negative to a positive pole Feel tingling, followed by a feeling of warmth Chemical reactions, increase blood flow, muscle reeducation, decrease swelling, spasm and pain Alternating current AC The flow of electrons reverse in direction once each cycle Special Considerations for Electrotherapy Contraindications Pacemakers Pregnancy When muscle contractions are not wanted Nonunited fractures Areas of active bleeding Near malignancies Electrotherapy Methods Moist electrode pads are placed on the skin Small pad is the active pad which brings the current to the body Larger pad is where the electrons leave the body Closer the pads are the shallower and more isolated the muscle contraction The farther apart the pads are, the deeper and more generalized the contraction Active exercise can be used at same time Ice packs, cold water immersion and ultrasound can all be combined with electrotherapy Iontophoresis Process which chemical ions are transported through the intact skin by an electrical current Polarity of the electrode used depends on the polarity of the ion introduced The most common used medication for iontophoresis are hydrocortisone and salicylates The patient should not experience discomfort or a burning sensation Treatment times are 10-20 minutes, once a day Mechanical/Manual Therapy Therapy where the direct use of the provider’s hands are being used Used in conjunction with or as supplement to to other methods Massage One of the oldest modalities used Manipulation Joint mobilization Massage Therapeutic and Physiological Effects Stimulating Cell metabolism Increasing venous flow and lymphatic drainage Increase circulation and nutrition Stretches superficial scar tissue Relaxes muscle Tissue Contraindications to Massage Acute injuries Hemorrhaging Infection Thromboses Nerve damage Skin Disease Possibility of Calcification Massage Methods Effleurage Superficial or deep stroking with the heels and palms of the hand Petrissage Kneading, hold soft tissue between the thumb and forefinger and alternately roll, lift, twist to loosen tissue Tapotement Cupping, hacking, pincing and percussive movements Massage Methods Vibration Trembling, forward and backward movement, rapid shaking of tissue by hand or machine Friction Pressure across muscle or tendons. Fingers and thumbs move in circular patterns, stretching underlying tissue Massage Use lubricants Oil, lanolin, lotion, powder Stroke toward the heart Increases venous return to reduce swelling Proper positioning Injured part made easily accessible, comfortable and relaxed Be confident Manipulation/Manual Therapy Mobilization of joints and soft tissue to allow proper functioning of a body part All movement is passive on part of the athlete Based on the concepts of joint play Gliding and rolling of one joint surface on another At no time should a provider attempt manipulation without education and practice Rehabilitation Unit 7 Definition Restoration to a functional level for daily living Return to an appropriate level of competitive fitness Individualized and Influenced by: Severity of injury Stage of tissue healing Type of Treatment (surgery, protocol) Strength of the muscles of the limb Pain on motion of the joint Joint swelling Sport specific demands Rules of Rehabilitation Create an environment for optimal healing Do no harm Be as aggressive as you can without doing harm If it hurts, don’t do it Goals of Rehabilitation Vigorous, intense BUT controlled exercise allowing return to competition Ensuring injured part is as optimally conditioned as possible Restoration of function to the greatest possible degree in the shortest possible time Goals must be realistic and reachable Realistic and Reachable Goals Increase range of motion Increase strength Increase joint mobility Increase endurance Encourage relaxation Enhance coordination and skill Improve joint stability Prevent re-injury Decrease pain Improve function Minimize atrophy and deconditioning Improve technique, posture and mechanics Decrease inflammation and swelling Improve motor control Equipment Specialized equipment is very useful This will not guarantee results if program is inadequate, if athlete is not motivated or there is poor supervision Possible to use little or no equipment As long as the program is carefully and knowledgeably designed for athletes needs and if athlete is adequately motivated and supervised Psychology of Rehabilitation Rehab is 75% psychological and 25% physical Rapport with athlete is critical (motivation and communication) Help athlete deal with fear, anger, depression, selfdoubt, and motivation Use a variety of exercise to achieve the same results and avoid boredom Involve injured athlete with the team as much as possible- meetings, functions and practice Components of a rehab program Program must be progressive increase amount of work performed at each session Use correct form to maximize results and prevent injury Strength Speed Endurance Flexibility Proprioception Sport Specific Skills- functional Common Mistakes in Rehab Look for the “culprit” not the “victim” Focusing on one single muscle group Not moving on until injured limb is equal or superior to the uninjured side Proprioception is often forgotten Postural defects, anatomical malalignment and biomechanical imbalances are neglected Sports specific skills are not incorporated SAID principle not incorporated Types of Exercise Isometric Isotonic Isokinetic Plyometrics Manual Resistance Concentric/Eccentric Contraction Open / Closed Chain ISOMETRIC EXERCISE Does not result in any movement of the joint Often performed against a fixed resistance Least effective form of strength improvement Static exercise since there is no movement Examples; Wall press, stationary press ISOTONIC EXERCISE The joint is moved through a range of motion against the resistance of a fixed weight The resistance is fixed and the speed is variable Dynamic movement since movement takes place Greatest strength gain takes place in the initial movement as the muscle attempts to overcome resistance / Least strength gain is at the mid point Examples: Bench press, arm curls, squat, heel raises ISOKINETIC EXERCISE Exercise where there is variable resistance and where the speed of the motion is set Resistance accommodates to match the force applied Dynamic contraction since there is maintenance of a constant velocity Advantage- visual readouts are possible which helps evaluate progress and acts as a powerful psychological stimulus for the athlete Disadvantage- Cost of isokinetic machines PLYOMETRICS A variety of exercises that utilize explosive movements to increase athletic POWER Maximize the stretch reflex Examples: Power jumps, leaps, bounds, throwing a weighted object- medicine ball Should be performed 2-3 days a week to allow full recovery from fatigue Strength should first be attained to provide stabilitycurrent injury is a contraindication Stretch Reflex The muscle is fully stretched immediately preceding the shortening of it An eccentric contraction occurs immediately before the concentric contraction The greater the stretch put on the muscle from its resting length immediately before the contraction the greater the load the muscle can lift or overcome Rate is more important than magnitude MANUAL RESISTANCE A provider adjusts the speed of movement and resistance to that best suited to the athlete’s needs Will vary according to the stage of rehabilitation and the state of fatigue Concentric Exercise Concentric exercises are related to positive work The muscle shortens as the weight is lifted Example: The up phase of a biceps curl The biceps is the muscle working concentrically ECCENTRIC EXERCISE Eccentric exercise is related to negative work Muscle lengthens or is forcibly stretched while the weight is lowered Greater strength gains More stressful work for muscles resulting in muscle soreness Example: Lowering a dumb bell during a biceps curl The biceps is the muscle that is working eccentrically Open Chain Exercise Exercise when distal segment is not fixed and is freely moving in space Functional for upper extremity Examples: Leg extension Leg flexion Abduction/Adduction exercise machines Functional activities such as throwing, jumping Closed Chain Exercise Exercise where distal segment is fixed Functional for lower extremity Examples: Standing leg press with sport cord Lunges Baps board Slide board Therapy Balls Phases of Rehabilitation There are three phases Phase 1- Acute First 48-72 hours Phase 2- Sub-acute 72 hours to about 2 weeks after injury Phase 3- Intermediate Last up to 6 months Phase 1- Acute First 48-72 hours Symptoms- redness, heat, swelling, pain, inflammation, loss of function Short Term Goals Decrease pain, swelling and inflammation Increase Range of Motion and Control Pain Maintain Cardiovascular conditioning Phase 1-Acute continued Emphasis of cardiovascular fitness Isometric contractions if immobilized Exercise the opposite unaffected limb may provide cross over reaction Muscle stimulation RICE used to control swelling Phase 2- Sub acute 72 hours to about 2 weeks Inflammation is decreasing and tissue is being repaired Begins as soon as pain and swelling are controlled and complete immobilization is no longer necessary Warm up the area prior to attempt exercise and ROM will allow tissue to respond more effectively Ice injured area after working it to prevent secondary swelling and effusion Phase 2- Sub Acute continued Short Term Goals Reach full range of motion Increase muscle strength, power and endurance to all muscle groups Maintain cardiovascular endurance to preinjury strength Begin proprioception training Amount of time needed for tissue repair is based on several factors: Degree of injury Location of injury Age Nutritional status Medical problems Medications Use of corticosteroids Phase 3- Intermediate Lasts up to 6 months Tissue is repairing, changing and remodeling to restore function Prepare for Specific Functional Exercises Including open and closed chain exercises
