3 Osteopathic Medicine: DO history Developed in the late 1800 s alongside allopathic (M.D.) medicine Founded by A.T. Still, M.D., who rejected the harsh drug treatments used then for manual medicine Still was accepted by the medical community but chose to start his own schools because his holistic philosophy was fundamentally different

4 Osteopathic Medicine: DO Defined Many D.O. s practice in typical allopathic settings as surgeons, internists, or primary care settings Traditional osteopathic doctors make up about 10% of all those trained and are those who continue to utilize their hands to manually treat patients.

5 Osteopathic Medicine: DO Defined A D.O. is different than the other therapists because, in the U.S., a D.O. is a medical physician Traditional osteopathic doctors use very specific forms of manual medicine, unlike any other manual therapist. An important note: A D.O. is not a therapist. When an osteopathic doctor places his or her hands on a patient, he or she is practicing medicine. Insurance companies reimburse D.O. s at a higher rate for osteopathic manual medicine than any other manual therapies

6 Osteopathic Medicine: DO Principles 1) The body is a unit; one cannot treat a part of the body without consider its entirety. 2) Structure and function are reciprocally interrelated. 3) The body is capable of self-regulation, self-healing, and health maintenance. 4) The nervous system controls, influences, and integrates all bodily functions. 5) Rational treatment is based on an understanding of these principles.

7 Osteopathic Techniques for Joint Pain counterstrain indirect balancing myofacial release cranial therapy lymphatic drainage facilitated positional release HVLA, muscle energy

9 Osteopathic Techniques: Direct Direct: Attempt to direct body parts into and often through their physiological and anatomical barrier Examples: Muscle Energy, HVLA (High Amplitude, Low Velocity), Stretching, ROM exercises Demo Great for Cervical, Mid-Back, Low back somatic dysfunctions (facet joints, intercostal areas, some tight muscles, frozen shoulders) in young, healthy patients Used by Chiropractors, Physical Therapists frequently

10 Osteopathic Techniques: Direct Pros: Often provides quick relief for patients, can encourage healthy physiology Cons: Rarely provides permanent changes to the tissue, patient has to return frequently to find relief Rationale: The body cannot adapt and hold to the often abrupt changes created by these often rapid lengthening therapies (that go beyond the physiologic barrier) Dangers: Can be damaging to body tissues, joints

11 Osteopathic Techniques: Indirect Indirect: Attempt to direct body tissues (muscle, bone, fascia, tendons) away from their anatomic or physiological barrier Examples: counterstrain indirect balancing myofacial release cranial therapy

12 Osteopathic Techniques: Indirect Pros: More sophisticated techniques as they work with the body s own physiology; great for older, postsurgical patients, after trauma; very effective and calming to the body; provide lasting, often permanent changes; not forceful--minimal risk of damaging tissue Rationale: The body can adapt to the physiological changes fostered by indirect techniques Cons: Require more patience and more time to do techniques; difficult for patients to do own their own; do not provide immediate popping sounds

14 Indirect Techniques: Counterstrain Used mostly by traditional osteopathic doctors, some chiropractors, and a few physical therapists Counterstrain: Developed by Laurence Jones, D.O. Definition: a passive positional technique that places the body in the position of greatest comfort, thereby relieving pain by reduction and arrest of inappropriate proprioceptor activity that maintains somatic dysfunction

15 Counterstrain: How does it help? A somatic dysfunction might be defined as any body part dysfunction that presents itself with a restriction of motion, tissue texture changes, asymmetry, or temperature changes For example: A knee joint sprain presents with restriction of motion The knee joint motion is most restricted at one point Likewise, the knee joint is also least restricted at one point Demo

16 Counterstrain: How Does It Work? Technique: Could be thought of as the opposite of stretching (as the goal is to find the greatest position of ease) Directed not at tissue damage itself but to the aberrant neuromuscular reflexes within the tissue In particular, counterstrain is directed at muscle spindles within the extrafusal fibers of muscles Muscle spindles are highly specialized sensory receptors which consist of a connective tissue sheath holding 5-12 intrafusal fibers (about 3mm long each)

17 Counterstrain: How Does It Work for Pain? On the polar, contractile ends of these intrafusal fibers, there are gamma motor neurons that terminate there after originating on the ventral horn The contractile ends of the intrafusal fibers are sensitive to changes in length (that occurs with muscle stretching) When the extrafusal fibers of the muscle are stretched, the intrafusal fibers are activated to resist the stretch through an efferent neurofeedback to the gamma motor neurons

18 Counterstrain: How does it Work for pain? The gamma motor neurons thus provide a necessary CNS control to allow appropriate stretching and resistance With more stretching of the large extrafusal muscle fibers (as often occurs with trauma, aka somatic dysfunction), there is more gamma motor stimulation so there is a greater reflexive resistance to the stretch created by feedback from the intrafusal muscle fibers

19 Counterstrain: How does it Work for pain? In short, the greater the trauma/ the greater the stretch, the more gamma excitement is present in the CNS Counterstrain works by approximating the muscle by passive shortening in order to decrease gamma gain (aka gamma excitement) to turn off the reflexive contraction by initiated by the intrafusal fibers of the muscle spindles A muscle that has been approximated can then return to its lengthened form allowing increased range of motion, less spasm, and ultimately less pain

23 Clinical Data: Counterstrain Effect of Counterstrain on Stretch Reflexes, Hoffmann Reflexes, and Clinical Outcomes in Subjects With Plantar Fasciitis JAOA Vol 106 No 9 September Conclusions: Clinical improvement occurs in subjects with plantar fasciitis in response to counterstrain treatment. The clinical response is accompanied by mechanical, but not electrical, changes in the reflex responses of the calf muscles.

24 Clinical Data: Counterstrain Stretch Reflex and Hoffmann Reflex Responses to Osteopathic Manipulative Treatment in Subjects With Achilles Tendinitis JAOA Vol 106 No 9 September Conclusion: The reduction of stretch reflex amplitude with OMT, together with no change in H-reflex amplitude, is consistent with Korr's proprioceptive hypothesis for somatic dys-function and patient treatment. Because subjects' soreness ratings also declined immediately after treatment, decreased nociceptor activity may play an additional role in somatic dysfunction, perhaps by altering stretch reflex amplitude.

27 Injectional Therapy for joint pain: Physiology of Acute Sprains Inflammation phase--damaged cells release cytokines and other mediators that cause vascular dialation and permeability PMLs, followed by macrophages enter the scene and along with other cells, stimulate the migration and proliferation of fibroblasts Proliferative phase of connective tissue healing--fibroblasts encourage synthesis of procollagen matrix (2-3 days after injury) Vascular buds form increasing blood supply (3-4 days) and new tissue forms

28 Injectional Therapy for joint pain: Physiology of Acute Sprains Remodeling phase: Collagen type I changes to collagen type III and fibrils increase along lines of stress to become tightly packed (2-3 weeks) Collagen thickens and increases to preinjury length but with only 50 to 70 % tensile strength (without additional injury to stimulate fibroblasts) With severe injury, the healing process may stop before the tissue is sufficiently competent for everyday use The term degenerative is often used to describe this inadequate healing and resulting body structure (other terms include chronic tendonitis, DDD, OA, etc.)

29 Injectional Therapy for joint pain: Degenerative, Chronic Tissue-Why painful? Nerve density at periosteum and periosteal attachments of tendons and ligaments is 2nd only to skin Without functional sufficiency, pain mechanoreceptors function as chronic nociceptors

30 Injectional Therapy for Joint Pain: Is blocking inflammation the answer? Cortisone injections: block inflammation, stop the healing cascade, decrease immune function (risking microbial infection), cause tendon weakening, atrophy, or ruptures Antinflammatory medications: block healing cascade

31 Injectional Therapy for joint pain: What is Proliferative Therapy? Prololiferative therapy (or Prolotherapy) is defined as the injection of irritant or proliferant solutions into the affected ligaments, tendons, and/or joints. This type of injection leads to local inflammation in the injected area. The localized inflammation triggers a wound healing cascade, resulting in the deposition of new collagen, New collagen shrinks as it matures. The shrinking collagen tightens the ligament that was injected and makes it stronger

32 Injectional Therapy: History of Prolotherapy The concept of Prolotherapy originated in the non-surgical treatment of hernias, varicose veins, and hemorrhoids, If the connective tissue in the veins becomes weakened, hemorrhoids and varicose veins form. Weakness in the collagen, of course, causes ligament laxity and tendon degeneration with resultant chronic pain. Most of the early innovators in injection treatment method were surgeons who were looking for methods to improve surgical outcomes or replace surgery with more conservative methods.

33 Injectional Therapy: History of Prolotherapy The injection of hernias, varicose veins, and hemorrhoids was called Sclerotherapy, because the injection "sclerosed," or scarred, the area. Hippocrates, the father of Western medicine, introduced heated metal probes into the dislocated and painful shoulders of javelin throwers. He believed that this would tightened the shoulder capsule by creating tough scar tissue and that the scar tissue would keep the shoulder in place. Dr. George S. Hackett developed modern prolotherpy beginning in 1939; Unlike the sclerotherapists, Hackett used an irritant that helped proliferate healthy collagen

34 Prolotherapy: Solutions, Technique Proliferative substances have varied over the decades but have included phenol, glycerin, sodium bicarbonate, dextrose, sodium morruhate, hypertonic saline Dextrose is commonly used as a proliferant today These substances are injected at the bony attachments of tendons and ligaments to improve their integrity

35 Prolotherapy: Explained Dextrose is thought to "dehydrate" the injected tissues, causing an injury signal for the body, and initiating the healing process. Dextrose has been shown to be a growth stimulant on it's own as well. This healing process is one of inflammation restarts the normal healing cascade that would occur with an acute injury

36 Prolotherapy: Clinical Evidence 1800 patients followed for 2 years; 80% showed marked improvement in upper and lower body pain; Hackett GS: Prolotherapy in whiplash and low back pain. Postgrad Med 27: , 1960 Two RCTs (160 participants) found that prolotherapy injections, given with spinal manipulation, exercise, and other therapies, are more effective than control injections for chronic low-back pain and disability.

37 Prolotherapy: Clinical Evidence 60% increase in collagen fibril diameter measured at 3 months after 6 weekly injections in patients with low back pain; Klein RG, Dorman TA, Johnson CE: Proliferant Injections for Low Back Pain: Histological Changes of Injected Ligagments and Objective Measurements of Lumbar Spine Mobility Before and After Treatment J Neurol Orthop Med Surg 10: , 1989 Osmolarity studies: Elevation osmolarity by as little as 50 mosm has been found to activate multiple growth factors including PDGF

38 Prolotherapy: Clinical Evidence Response of Knee Ligaments to Prolotherapy in a Rat Injury Model; Am J Sports Med July 2008 vol. 36 no Conclusion: Dextrose injections increased the crosssectional area of MCLs compared with saline-injected and uninjured controls. Dextrose injections did not alter other measured properties in this model.

39 Prolotherapy: Clinical Evidence A systematic review of four injection therapies for lateral epicondylosis: prolotherapy, polidocanol, whole blood and platelet-rich plasma; British Journal of Sports Medicine 2009;43: Conclusions: There is strong pilot-level evidence supporting the use of prolotherapy, polidocanol, autologous whole blood and platelet-rich plasma injections in the treatment of LE.
