Overview and Description
Manual therapy is a “hands on” approach to assessment and treatment of musculoskeletal disorders whereby a practitioner manipulates the soft tissue, muscles, tendons, joints and/or bones of a relatively passive patient.1
Common manual therapies include osteopathic manipulative treatment (OMT), chiropractic, massage, traction, reflexology, cupping, and acupressure as well as manual physiotherapies such as those developed by Rolfe, Cyriax, Mennell and others. Osteopathic and chiropractic techniques dominate this field of medical treatment in the United States.2 Massage therapy remains a popular out-of-pocket modality for patients, but it is rarely covered by health insurance.3
- Different musculoskeletal manual therapies engage different neurophysiologic principles, including hyperactive gamma motor neurons associated with spasms, Golgi tendon organ reflexes, reciprocal innervation reflexes and elastic stretch reflexes4
- The therapeutic principles of Osteopathic manual medicine are based upon the understanding that the human body functions as a unit with an inherent ability to self-regulate and self-heal4
- In the osteopathic model,2 structural or functional abnormalities of the musculoskeletal system include:
- asymmetry of related parts
- impaired range of motion (hyper- or hypomobility)
- abnormal texture of soft tissue
- Chiropractic focuses on the spine, crediting vertebral malalignment as causing pressure on nerves which may affect visceral function and lead to disease5
Practitioners of manual medicine view the musculoskeletal system as an “integral and interrelated part of the total human organism.”4 Unresolved somatic dysfunction often leads to postural abnormalities and asymmetries (providing an example using inter-related muscle groups will help provide context). Areas of tightness persist and inhibit muscle function, causing areas of noted weakness. These asymmetries then increase the risk of further musculoskeletal injury and pain.
Relevance to Clinical Practice
Separate studies and systematic reviews have shown low to moderate evidence that manual therapy improves pain and function, and may be equal to guided exercise for back pain,6,7,8 neck pain9 and headaches10, while the combination of manual therapy and guided exercises together tends to be superior to either alone.
Several studies have shown low to moderate evidence that manual therapy improves pain and function in tempomandibular joint disorders11,12 and shoulder pain,13,14,15 although these have not shown to be superior to standard treatments.
- A full neurological exam is completed to “clear” the patient prior to proceeding with the remainder of the exam and treatment. As detailed below, the most common complications of manual therapies have been cervical arterial dysfunction.16
- The structural exam
thenfollows the neuro exam and attempts to identify areas of asymmetry, abnormal range of motion and tissue texture abnormalities (hypertonicity, warmth, boggy edema) that would qualify as somatic dysfunction. “Hands on” inspection, palpation, ranging of the patient’s joints, and gait analysis can help identify functional deficits.4
- Additional areas of focus include leg lengths, iliopsoas length (Thomas test), and sacroiliac excursion and obliquity. Areas of spinal hyper- and hypomobility may also be identified.4
- Function can be affected negatively by structural abnormalities, including basic activities of daily living, work and leisure activities.
- Comparison of passive and active range of motion (before and after treatment) can help elucidate functional deficits.
When warranted by clinical examination, blood work, both routine (such as CBC, ESR, CRP) and disease specific (such as ANA, RF, TSH and antibodies) can evaluate for systemic disorders or inflammatory conditions some malignancies, and help to facilitate the appropriate referral to a specialist.
- Plain film X-rays and Magnetic resonance imaging with and without contrast can rule out infections, malignancies and neurological compromise that may increase the risks of manipulation.
- Standing radiographs can be used before and after manipulation to check pelvic symmetry, scoliosis or leg lengths. Fann and colleagues used such radiographs to measure pelvic obliquity.17
Supplemental assessment tools
- Goniometry to measure specific joint or gross spine range of motion can be used before and after treatments to attempt to objectively measure effectiveness, including but not limited to
- shoulder range of motion before and after Spencer technique
- cervical range of motion before and after muscle energy
- Pain diagrams can be used to measure effectiveness of pain interventions.
- Many surface measurement devices advertised as methods for measuring tissue texture and temperatures correlating to pain levels are largely unproven.
Predictions of outcomes
Despite manual therapy remaining popular with patients and practitioners, there is limited high quality evidence for its effectiveness.18
Licciardone found that both patients who received osteopathic and sham manipulation reported greater improvements in back pain, greater satisfaction with back care throughout the trial, better physical functioning and mental health one month posttreatment, and at six months had fewer co-treatments compared to control subjects who had no interventions. Proposed similarities have included placebo effect from increased time spent with patients during encounters or effects from range of motion and touch.19
Haas and colleagues showed efficacy in chronic patients, but not in acute patients.20
Specific secondary or associated conditions and complications
- Patients must give consent for treatment with manual techniques. Complications from manual medicine are rare but incidents have been described. The primary severe complication remains to be cervical arterial dysfunction in the setting of cervical manipulation, leading to cerebrovascular ischemic events.16
- Case reports and case series have shown that chiropractic manipulation of the cervical spine with hyperextension and contralateral rotation of the head significantly reduced vertebral artery circulation, which may injure the vessels of the head and neck, most frequently the upper cervical segments of the vertebral artery though the intracranial vertebral artery and carotid arteries may also be negatively affected. This may lead to vertebral basilar artery dissection, stroke and potentially even death.21
- Atlanto-axial instability (as seen potentially in Rheumatoid Arthritis and Down Syndrome) is an absolute contraindication for many cervical manual therapy techniques. Manipulation in these patients may cause neurologic damage4,22
- Case reports have shown rare neurologic presentations following manual therapies including nerve damage,23 myelopathy24 and death25
Available or current treatment guidelines
- Manual medicine became more widely accepted after an evidence review policy statement was promoted as a successful treatment modality in a set of National Low Back Pain Guidelines.
- In osteopathy, Principles of Manual Medicine is considered the authoritative textbook.2
- In 2007 the Academy for Chiropractic Education published updates to their guidelines, entitled Manual Medicine Guidelines for Musculoskeletal Injuries (updated in 2009).26
- The American Journal of Obstetrics and Gynecology published the PROMOTE (Pregnancy Research on Osteopathic Manipulation Optimizing Treatment Effects) study which showed Osteopathic manipulation was both safe in pregnant woman and provided significant treatment effects for pain and back-related functioning.27
At different disease stages
- Acute (up to 6 weeks): Interventions at this stage may be limited by severe pain, because “guarding” may limit the techniques available. In such situations, other modalities such as medications, modality applications or injections can be utilized to reduce pain acutely and as the patient becomes more relaxed, the muscles can better benefit from manipulation techniques.
- Subacute (6 to 12 weeks)
- Rehabilitation in the form of stretching and strengthening exercises must be employed in this stage.
- Manipulation at this stage may be used to correct dysfunctions and for symptom relief and may result in the use of less pain medication or injections.
- Prevention discussions should begin at this stage. These topics may include configuration of the workstation, attempts to improve fitness, and risky behaviors such as poor lifting technique.
- Chronic/stable (greater than 12 weeks)
- The chronic/stable patient can benefit not only from manual medicine treatments, but also from a multidisciplinary rehabilitation approach.
- Attention to “re-activation” must occur and restore the patient to a better functioning state despite the pain they may have.
- Manipulation can be used as a palliative strategy if recurrent treatments preserve function and lead to fewer medications with potential side effects.
- Pre-terminal or end of life care: The use of manipulation in cancer patients remains controversial. Depending on the individual, manipulation may be utilized to ease pain and suffering. Lafferty and colleagues recommended that complementary and alternative medicine techniques be used on a case by case basis to relieve pain in terminally ill patients.28 Historical concern for massage in cancer patients existed, however a comprehensive review by Corbin29 found there has been no significant evidence that massage therapy can spread cancer, though direct pressure over a tumor is nonetheless usually discouraged. Massage in cancer may lower pain, anxiety, depression and nausea and improve sleep; gentle effleurage may increase NK cells, improving immunity.29
Patient & family education
Manual medicine may be met with skepticism and/or distrust. The practitioner needs to educate the patient and family about the reasons manual medicine may work in their case, including understanding the basis for treatment.
Initial skepticism bias for manual treatment may reduce efficacy.
Cutting Edge/ Emerging and Unique Concepts and Practice
- To combat the rising opiate epidemic, JCAHO released new pain management standards for accredited organizations in 2018.30
- There is increasing evidence to support incorporating integrative medicine, including manual therapies, in hospitalized inpatients. 31,32
Gaps in the Evidence- Based Knowledge
- Despite numerous positive case series, a lack of randomized, double-blind, placebo-controlled studies exists for manual therapies due to inherent difficulties with blinded or sham manipulation.
- The use of manipulation in cancer patients remains controversial (possibly safe, possibility for tumor spread).
