A Kinetic Chain Approach to Musculo-Skeletal Pain Combining Manual Therapies, Nutrition and Corrective Exercise. GEOFF LECOVIN DC ND L.Ac CSCS ADAM RINDE, N.D., ASCM-HFI., CES Integrative Approaches to Pain This class is a synthesis of cutting-edge chiropractic, osteopathic, naturopathic, massage, nutrition and dry needling techniques and principles. Practitioners and students will learn the different phases of pain and how to effectively assess and manage each phase with physical medicine, exercise, nutrition and prescription drugs. Participants will refine their skills in soft tissue and joint manipulative therapy and get exposure to dry needling. They will be able to effectively manage the most common orthopedic and sports medicine problems seen in private practice. Course Objectives Understand the different phases of pain Differentiate between an orthopedic approach and Integrative approach to musculoskeletal pain Understand the significance in assessing the kinetic chain Learn about common distortion patterns Understand the role of trigger points Understand the significance of perpetuating factors Learn how to assess musculoskeletal conditions Learn how to decide which manual therapy or modality is indicated Understand the role of corrective exercise as part of the treatment plan and prevention PAIN “An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described by the patient in terms of such damage.” International Association for the Study of Pain 3 PHASES OF PAIN 1. Immediate/Nociceptive 2. Acute/Inflammation 3. Chronic IMMEDIATE /NOCICEPTIVE PAIN Induced by extrinsic factors where there could be a threat of tissue damage Acute onset e.g. cut, burn, slap Over 90% will recover within a few weeks Pain messages are carried by A-Delta and C Fibers Good prognosis ACUTE INFLAMMATION Actual tissue damage e.g. strain/sprain Recognized by signs of inflammation- redness, increased local temperature, and swelling Occurs as a result of substances released by damaged tissue cells (*which are necessary for repair) Pain messages are carried by C-fibers Self limiting Responds to Naturopathic therapies or NSAIDS, analgesics and rest CHRONIC PAIN 1. 2. 3. Ongoing nociception or inflammation Psychological Neuropathic- functional and structural alterations within the Neuromusculoskeletal system Structure vs Function Structure (orthopedic approach)- focuses on the pathology of static structures; emphasizes diagnosis based on localized evaluation and special tests. Function- recognizes the function of all processes and systems within the body, rather than focusing on a single site of pathology. *The structural approach is necessary and valuable for acute injury or exacerbation, the functional approach is preferable when addressing chronic musculoskeletal pain. Traditional Orthopedic Approach Isolated joint kinematics Uniplanar Isolated muscle strength Morphologically oriented Integrative Functional Approach Focuses on all kinetic chain components (muscular, articular, neural) Optimum acceleration, deceleration and dynamic stabilization in multiplanar (saggital, frontal, transverse) movements Enables synergistic production and reduction of force and dynamic stabilization Maintains optimum length-tension and force-couple relationships of agonists and antagonists Allows optimum joint arthrokinematics and neuromuscular efficiency Regional Interdependence Seemingly unrelated impairments in a remote anatomical region may contribute to, or be associated with, the patient’s primary complaint Wainner et al JOSPT 2007 Optimum Alignment Alignment of the musculoskeletal system allowing posture to be balanced with center of gravity Ability of the neuromuscular system to perform functional tasks with the least amount of energy and stress on the kinetic chain Optimum muscle length-tension relationships at which a muscles are capable of developing maximal tension KINETIC CHAIN CONCEPTS Proprioception- the cumulative neural input to the CNS from mechanoreceptors (specialized neural structures that convert mechanical information into electrical information that is relayed to the CNS) Length-Tension Relationship- the optimal length at which a muscle can produce the greatest force Force-Couple Relationship- the synergistic action of muscles to produce movement around a joint Arthrokinematics-The ability of a joint to move through its biomechanical range of motion Optimal Neuromuscular Control Normal length tension relationships Normal force couple relationships Normal arthrokinematics *Optimal sensorymotor integration *Optimal neuromuscular efficiency *Optimal tissue recovery Example of Kinetic Chain Dysfunction and Pain Excessive pronation- metatarsalgia, bunion, PF, neuroma Excessive tension in tibialis posterior and peroneous longus- shin splints Knee stress- tendonitis, injury susceptibility Lateral thigh tension- tight hamstrings, ITB, TFL (e.g. PFS) Abnormal L-P rhythm- anterior pelvis rotation Increased lumbar lordosis- tight psoas, erector spinae and latissimus dorsi- Lumbago Downward traction of the scapula with shoulder movement Excessive tension in outer shoulder muscles Neck and shoulder pain MUSCLE ACTION CLASSIFICATIONS Agonists- prime movers Antagonists - act in direct opposition to prime Synergists - assist prime movers during functional movers movement patterns. Stabilizers- support or stabilize the body while the prime movers and the synergists perform the movement patterns Neutralizers- muscles that counteract the unwanted action of other muscles Functional Muscle Division Stabilization Group Movement Group Stabilization Group (Local Muscles/Inner Unit) Peroneals Tibialis posterior/Anterior VMO Gluteus Medius Pelvic floor muscles Transverse Abdominus Internal Oblique Multifidus Deep erector spinae Transversospinalis group Diaphragm Serratus anterior Middle/Lower Trapezius Rhomboids Teres Minor Infraspinatus Posterior deltoid Lomgus Coli/Capitus Deep cervical Stabilizers Movement Group (Global/Outer Unit) Gastocnemius/Soleus Adductors Hamstrings Gluteus Maximus Psoa TFL Rectus Femoris/Quadriceps Piriformis Erector Spinae QL Rectus abdominus External oblique Pectoralis Major/Minor Latissimus Dorsi Teres Major Upper Trapezius Levator Scapulae SCM Scalenes FUNCTIONAL MOVEMENT DIVISION SUMMARY Stabilization System (inner core) Local muscles for joint support and posture Being prone to weakness and inhibition Less activated in most functional movement patterns Fatigue easily during dynamic activities Predominantly slow twitch Movement System (outer core) Global muscles for movement Being prone to developing tightness Readily activated during most functional movements Overactive in fatigue situations or during new movement patterns Compensate (synergistic dominance) during fatigue states Predominantly fast twitch Low Back Pain Chronic low back pain represents 85-95% of the population Lack of appropriate neuromuscular response of the muscles stabilizing the LPHC Patients unable to preferentially recruit the inner unit musculature of the LPHC Recruitment of motor units from the outer unit leading to synergistic dominance, altered normal force couple relationships, length-tension relationships, joint kinematics and neuromuscular control CAUSES OF MUSCLE IMBALANCES Pattern overload Aging Decreased recovery and regeneration following an activity Repetitive movement Lack of core strength Immobilization Cumulative trauma Lack of neuromuscular control Postural stress Postural Distortion Patterns Altered Reciprocal Inhibition- The process whereby a tight or overactive agonist inhibits its functional antagonist. This results in altered force couple relationships and synergistic dominance and leads to the development of faulty movement patterns and poor neuromuscular control. Synergistic Dominance-The process whereby synergists compensate for a weak or inhibited prime mover in attempts to maintain force production and functional movement patterns. This causes faulty movement patterns, which leads to tissue overload, decreased neuromuscular efficiency and injury. Arthrokinetic Dysfunction- A biomechanical dysfunction in two articular partners, resulting in abnormal joint movement (arthrokinematics), muscle inhibition and proprioception disturbance. Myofascial dysfunction (trigger points) CNS changes MYOFASCIAL PAIN SYNDROMES A myofascial trigger point is a highly localized and hyperirritable spot in a palpable taut band of skeletal muscle fibers. Travell and Simons TRIGGER POINT SYMPTOMS 1. Onset after micro or macro trauma 2. Local or referred pain (RPP) 3. Pain with muscle contraction 4. Muscle stiffness and restricted joint motion 5. Muscle weakness 6. Paresthesia and numbness 7. Proprioceptive disturbance- dizzy, lack of balance 8. Autonomic dysfunction- pilomotor reflex 9. Edema and celllulite- decreased circulation and waste accumulation 10. Sleep disturbance Pathogenesis Over stretching/over shortening Overloading of tissue Micro-trauma Destruction of sarcoplasmic reticulum Release of calcium++ Sustained muscle contraction Physical Findings of MTrPs Taut band Tender and painful nodule to palpation Patient pain recognition Local twitch response Limited range of motion Muscle weakness Positive stretch sign- pain of mechanical or neural origin exhibited during myofascial stretching that can be improved with trigger point therapy to the muscle Classification of Trigger Points Satellite Attachment Active *Limit ROM *Weakness *Local & Referred pain Latent *Limit ROM *Weakness *Pain only with compression Classification of Trigger points Active TP *Limit ROM *Weakness *Local & Referred Pain Latent TP *Limit ROM *Weakness *Pain only with compression TRIGGER POINTS ARE KNOWN TO CAUSE Headaches Neck and jaw pain Low back pain Carpal tunnel syndrome Joint pain (arthritis, tendonitis, bursitis, ligament injury) Tennis elbow Contributing cause of scoliosis Earaches Dizziness Nausea Heartburn False heart pain Arrhythmia Genital pain Sinus pain/congestion Colic and bed wetting Depression, CFS, lowered resistance to infection Kinetic Chain Imbalances Imbalances in muscle length Altered normal length-tension relationships Abnormal force-couple relationships Altered reciprocal inhibition of the functional antagonist Synergistic dominance Faulty movement patterns Initiation of the cumulative injury cycle Cumulative Injury Cycle Muscle spasm Adhesions Altered neuromuscular control Inflammation Tissue trauma Muscle imbalance Cumulative injury cycle Postural Distortion Patterns When a chain reaction evolves in which some muscles shorten and others weaken, in predictable patterns of imbalance Janda 1. Upper crossed syndrome Lower crossed syndrome 2. Looking at the Body joint-by-joint From the Bottom Up: • • Ankle mobility (particularly sagittal) Knee stability Hip mobility (multi-planar) Lumbar Spine stability Thoracic Spine mobility Gleno-humeral stability (The joints alternate mobility and stability) Injuries relate closely to proper joint function Problems at one joint usually show up as pain in the joint above or below Patient History OPQRST O- Onset P-palliative/provocative Q-quality R-radiation S-severity T-temporal factors FAOMASH (family hx, accidents, other, meds, allergies, surgical history, hospitalizations) *The patient will tell you what’s wrong if you know how to ask Patient Examination IPPIRONEL I-inspection P-palpation P-percussion I-instrumentation R-range of motion (active and passive) O-orthopedic tests N-neurological tests i.e. motor, sensory E-extra tests e.g. x-ray, MRI, CT L-lab Posture Dynamic Structural efficiency Neuromuscular efficiency Balance and equilibrium Functional strength Static Posture Landmarks Side: An imaginary line should run slightly anterior to the lateral malleolus, through the middle of the femur, center of shoulder and middle of the ear Posterior: An imaginary line should run from between the medial malleoli, up through the spine and center of the head Anterior: An imaginary line should run from between the medial malleoli, up through the sternum and center of the head Common Dysfunctional Patterns Ankle/Foot- Pronation/Turns out Knee- Hyperextended/Moves in or out Hip- Uneven Lumbar/Pelvis/Hip- Lordosis/scoliosis Thoracic- kyphosis/scoliosis Scapulae- Uneven/abducted Cervical- Lordosis/scoliosis Head- Forward Observing Dynamic Posture Relates to the basic functions- squatting, pushing, pulling and balancing Shows muscle and joint interplay Can uncover postural distortions and imbalances in anatomy, physiology and biomechanics that can lead to injury Movement assessment 1. 2. 3. 4. 5. Identifies movements that consistently causes pain Identifies altered motor control, abnormal length-tension relationships, relative flexibility and faulty movement patterns that can cause pain and can lead to pathology e.g. arthritis Movement impairment is classified by the direction of movement that causes pain e.g. movement classifications in the spine: flexion, extension, rotation, flexion/rotation, extension/rotation Testing is performed sitting, standing, side-lying, prone, supine and in a quadruped position; bilaterally and unilaterally Reproducing the pain is the key to both identifying the problem and effective treatment through therapy and corrective exercises/activities Kinetic Chain Check Points (anterior/posterior/lateral) Foot/Ankle– Straight ahead w/ neutral position at the ankle Knee– Straight ahead in line w/ 2nd and 3rd toes Lumbo-Pelivic-Hip Complex– Neutral spine with abdominals drawn in Shoulder and cervical spine– Neutral, center of shoulder in line with center of hip joint Head– Neutral, center of ear in line with center of shoulder Dynamic Inspection (Overhead Squat) SPECIAL IMAGING Help or Hindrance? Lumbar MRI’s were done on 98 people with no hx of back or leg pain. 36% had normal discs at all levels, 52% had bulging discs at one or more levels, 27% had a disc protrusion and 1% had an extrusion. “The discovery by MRI of bulges or protrusions in people with low back pain may frequently be coincidental.”(NEJM,1994) GOAL OF TREATMENT 1. 2. 3. 4. 5. 6. 7. Control the pain and break the pain cycle Break chemical and Mechanical feedback loop that maintains muscle contraction Increase circulation that has been restricted by contracted tissue Lengthen shortened muscles Reconditioning and strengthening weak muscles Correct movement patterns Prevention of recurrence through an appropriate exercise program TREATMENT Provocative Active Resisted Functional Proprioceptive Effective Treatment Options Ischemic compression Injection techniques Dry needling Soft tissue manipulation Muscle energy technique (MET) Joint manipulation Friction massage Ultrasound Spray and Stretch Contrast therapy Corrective exercise Supportive taping Diet and nutrition to aid in repair Progressive Pressure Release Technique Apply progressive pressure to point of tissue resistance for 45-60 seconds. Hold until resistance dissipates. Repeat procedure 3-4 times each time moving to a deeper barrier Pressure is to patient tolerance Have patient deep breathe Release pressure quickly to produce vasodilation and elimination of the local ischemia Identify and treat satellite trigger points Follow by stretching (30 sec) and breathing Post treatment heat or cold applications SOFT TISSUE RELEASE TECHNIQUE (NMR- 97112) Specific contact is made on the muscle Traction is applied to the tissue in order to trap the lesion The muscle is moved either actively or passively through the line of injury The stretch is held for 1-2 seconds Repetitions are done in different positions and planes of motion (8-10 times) EFFECTS OF SOFT TISSUE RELEASE 1. STR stretches and softens scar tissue/adhesions 2. Pain input messages to limbic system are reprogrammed 3. Muscle length, flexability and memory are regained Manipulation Considerations 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Doctors position Patients position Doctors contact Patients contact Line of drive Joint type and normal motion Respiration Patient’s eye position Psycho-somatic influences Distraction techniques ACTIVE ISOLATED STRETCHING (Mattes) 1. 2. 3. Myofascial stretching of isolated muscles which avoids activating the protective myotatic reflex contraction Stretch through anatomical plane of attachments Contract the antagonistic muscle to facilitate a release in the stretched muscle (reciprocal inhibition) Ten repetitions for two seconds HYDRATION & RESPIRATION 1. 2. 3. The connective tissue matrix is an important water storage compartment Hydration promotes smooth, non-friction mechanical movement and effective nerve conduction Respiration expedites water absorption Tissue Pressure Lengthening 1. 2. 3. 4. 5. Stretching used to increase the extensibility of muscle and connective tissue, resulting in increased range of motion at a joint Static- passive Active- using agonists and synergists Neuromuscular- PNF Functional- using the body’s momentum Neurodynamic- neural structures Activate Isolated (intramuscular) Strengthening: Exercises used to isolate a particular muscle in order to increase the force production capabilities through concentric-eccentric muscle actions e.g. Scaption exercises *Strengthening exercises to start after a 70% of the normal range of motion has been achieved (empirical observation) Integrate Integration Techniques (Intermuscular): Re-educating the nervous system on movement patterns and muscle synergies in a dynamic manner (eccentric, isometric, concentric) e.g. Squat to row PERPETUATING FACTORS 1. 2. 3. 4. 5. 6. Mechanical Stresses Nutritional/Dietary factors Metabolic and Endocrine Inadequacies Psychological factors Chronic Infection Other (allergy, sleep, improper breathing, dehydration, smoking, caffeine, medications, visceral disease) MECHANICAL STRESS 1. 2. 3. 4. Structural- body asymmetry and disproportion e.g. leg length discrepancy, long second metatarsal and short first metatarsal Postural e.g. poor posture, poorly fitting furniture, poorly adjusted glasses, ergonomics Constriction of muscles e.g. poor fitting clothing Degenerative joint disease NUTRITIONAL FACTORS (VITAMINS AND MINERALS) Nutritional inadequacies cause impairment of energy, cell metabolism and function ,which reduces the ability of the muscle to meet extra demands and metabolic stress Nutrients Play a role in the synthesis of neurotransmitters, protein, carbohydrate and fat metabolism, DNA synthesis, collagen synthesis and proper nerve and muscle function Low levels should be treated as they may not be adequate for optimum health Deficiency increases irritability of trigger points and nerves NUTRITIONAL DEFICIENCY B1- important for energy and synthesis of neurotransmitters. Potentiates the effectiveness of thyroid hormone B6- important in lipid and protein metabolism and the synthesis of neurotransmitters B12- essential for energy and DNA synthesis and in fat, carbohydrate and protein metabolism Folic Acid- Important for synthesis of DNA, cell metabolism and for normal brain function and development C- important in collagen synthesis and synthesis of serotonin and norepinephrine Calcium, Magnesium, Potassium and Iron- Important in muscle contraction and function Naturopathic Approaches to Inflammation Antioxidants: A, E, C, Se, Zn, CoQ10 C/Bioflavonoids- 1000mg 3x/day Magnesium (citrate)- 300mg 2x/day Fish Oil (18% EPA & 12%DHA)- 10g per day (at least 3g EPA) Bromelain- 1000-2000 MCU 4x/day away from food Quercetin- 500mg 3x/day Boswellia- 400mg 3x/day Glucosamine and Chondroitin Sulphate- 500mg of each 3x/day Topical DMSO Topical Biofreeze Hydrotherapy Guided imagery/systematic relaxation/hypsosis Dietary Factors in Inflammation Phytonutrients- vegetables and fruits Green/Black tea Garlic, Ginger, Turmeric, Cinnamon etc. Consume low glycemic load carbohydrates (insulin connection) Eat small frequent meals to ensure glycemic regulation Omega 6:Omega 3 should be <4:1 Decrease meat, dairy, shellfish and refined carbohydrates/fats Decrease caffeine and alcohol Optimize digestion and bowel habits Identify food reactions METABOLIC AND ENDOCRINE 1. 2. 3. 4. When energy metabolism of the muscle is compromised as a result of metabolic or endocrine imbalance it perpetuates trigger point activity e.g. Hypoglycemia Hypothyroid Menopause Hyperuricemia Allergy/Infection Can perpetuate trigger point activity, possibly due to histamine release PSYCHOLOGICAL FACTORS 1. 2. 3. 4. 5. There is a decrease in brain serotonin which causes increased sensitivity and low oxygenation of the tissues e.g. Stress Depression Anxiety Insomnia Fatigue Tension Myositis Syndrome The mind body connection Conscious or Repressed Unconscious Emotions Stress Abnormal Autonomic Activity Reduced Local Circulation of Blood Mild Oxygen Deprivation Muscle Pain Nerve pain/Numbness/Tingling/Weakness Tendon Pain Practical Applications Evaluation and Treatment Cervical spine Thoracic spine Lumbo-Pelvic-Hip complex Upper ¼ - Shoulder, elbow, wrist, hand Lower ¼ - knee, ankle, foot Practical Format Common patterns of dysfunction Functional anatomy and biomechanics Assessment/Examination Treatment Trigger point release Muscle release therapy Friction massage Joint manipulation Stretching Corrective exercise (inhibit, lengthen, activate, integrate) References NASM Leon Chaitow, ND., DC Warren Hammer, DC Vladimir Janda, MD Craig Liebension, DC Paul Chek Shirley Sarhmann Peter Levy, DC Stuart Taws, LMP SLACK Hands on seminars Chan Gunn, MD Stuart McGill Gray Cook, PT
