[The diagnosis of posttraumatic neuroma via sonography and CT].

The sonographic CT and myelographic findings in three peripheral amputation neuromas are described, as well as a cauda equina neuroma following a tear of the lumbar plexus. Sonographically, the peripheral neuromas produced low intensity echoes with sharp differentiation from their highly echogenic surroundings. On CT the neuromas were hypodense, compared with muscle, measuring between 40 and 60 HU and showing only minimal enhancement after contrast. The cauda equina neuroma was shown on myelography as an intradural filling defect situated on the cranial aspect of a traumatic pseudomeningocoele. In view of their characteristic appearances, and the possibility of identifying trigger points, sonography appears to be the method of choice in the diagnosis of peripheral neuromas.

Efficacy of static magnetic field therapy in chronic pelvic pain: a double-blind pilot study.

OBJECTIVE: The aim of the study was to determine the efficacy of static magnetic field therapy for the treatment of chronic pelvic pain (CPP) by measuring changes in pain relief and disability. STUDY DESIGN: Thirty-two patients with CPP completed 2 weeks and 19 patients completed 4 weeks of randomized double-blind placebo-controlled treatment at a gynecology clinic. Active (500 G) or placebo magnets were applied to abdominal trigger points for 24 hour per day. The McGill Pain Questionnaire, Pain Disability Index, and Clinical Global Impressions Scale were outcome measures. RESULTS: Patients receiving active magnets who completed 4 weeks of double-blind treatment had significantly lower Pain Disability Index (P <.05), Clinical Global Impressions-Severity (P <.05), and Clinical Global Impressions-Improvement (P <.01) scores than those receiving placebo magnets, but were more likely to correctly identify their treatment (P <.05). CONCLUSION: SMF therapy significantly improves disability and may reduce pain when active magnets are worn continuously for 4 weeks in patients with CPP, but blinding efficacy is compromised.

Myofascial origins of low back pain. 1. Principles of diagnosis and treatment.

Myofascial trigger points (TPs) are frequently overlooked sources of acute and chronic low back pain. An active myofascial TP is suspected by its focal tenderness to palpation and by restricted stretch range of motion. The restricted lengthening of the muscle is due to the tense band of muscle fibers in which the TP is located. The presence of a TP is confirmed by a local twitch response and by reproduction of its known pattern of referred pain, which matches the distribution of the patient's pain. Only an active TP causes a clinical pain complaint; a latent TP does not. The pain can be relieved by the stretch-and-spray procedure, ischemic compression, or precise injection of the TP with procaine solution. Relief is usually long lasting only if mechanical and systemic perpetuating factors are corrected.

Myofascial origins of low back pain. 2. Torso muscles.

Trigger points (TPs) in muscles of the lower torso associated with the spine are an important cause of low back pain. The quadratus lumborum is the muscle most commonly involved, but TPs located there are often overlooked because of inadequate physical examination techniques. TPs in the lower rectus abdominis refer pain horizontally across the low back, and those in the iliopsoas refer pain in a vertical pattern, parallel to the lumbosacral spine. The pain pattern of TPs in the serratus posterior inferior is noted in the region of the muscle itself.

Myofascial origins of low back pain. 3. Pelvic and lower extremity muscles.

Gluteal, pelvic, and lower extremity muscles are common sites of origin of myofascial low back pain. Trigger points (TPs) in the gluteus maximus and medius muscles refer pain locally to the gluteal and sacral regions, while those in the gluteus minimus are likely to refer pain down the lower extremity as far as the ankle on the same side. TPs in intrapelvic muscles refer pain chiefly to the pelvic region. Besides producing referred myofascial pain, TPs in the piriformis muscle can cause symptoms of entrapment of the peroneal portion or all of the sciatic nerve. TPs in the soleus muscle may refer pain to the sacroiliac joint.

Nerve blocks and chronic pain states--an update. 2. Clinical indications.

With the unfortunate exception of the differential spinal block, diagnostic nerve blocking has become somewhat obsolete with the development of newer, more sophisticated diagnostic technology. Therapeutic nerve blocks remain useful in treating patients with various terminal cancers, some forms of back pain, tic douloreux, causalgia, reflex sympathetic dystrophy, and many trigger point syndromes. For dysfunctional and pain-disabled patients (rated as class 1 or 3 on Emory Pain Estimate Model), block therapy must be structured in comprehensive pain rehabilitation programs.

Nonarticular pain syndromes. Differentiating generalized, regional, and localized disorders.

Nonarticular pain syndromes, although not inherently crippling, can have significant impact on patients' comfort, daily activities, and job performance. These syndromes include fibromyalgia, bursitis, tendinitis, and localized myofascial pain syndromes. Although differentiating these conditions from one another may be difficult, early diagnosis and follow-up are important for determining appropriate treatment. Depending on the diagnosis, treatment may include use of nonsteroidal anti-inflammatory drugs, analgesics, or corticosteroid injections; trigger-point desensitization therapy; physical therapy; and patient education.

Characterising phantom limb phenomena in upper limb amputees.

A systematic descriptive survey was carried out on a clinic population with acquired upper limb amputation in which clear distinctions were made between phantom experiences, pre-amputation pain and stump pain. It was found that of 76 participants 96% reported phantom experiences and 84% were currently experiencing phantom limb phenomena (PLP). Sixty-nine percent (69%) of those currently experiencing phantom phenomena stated that the phantoms were painful. Significant relationships were found between frequency of phantom experiences and side and level of amputation. In addition, the presence of 'trigger' points reported by a sub group of participants was found to be associated with the frequency of phantoms and painful phantoms. This finding could provide support for cortical reorganisation post amputation. It is suggested that detailed individual 'profiling' of phantom experiences is important and would have the following implications: it would contribute to existing knowledge and provide new insights into the central nervous system's reorganisation post-amputation; it would provide an accurate way of representing amputees' anomalous perceptions; it would alert health professionals to the presence, variety and extent of PLP following amputation.

Length-tension relations of the masticatory elevator muscles in normal subjects and pain dysfunction patients.

Myofascial pain and dysfunction is the primary diagnosis in a large proportion of facial pain complaints. Myofascial disease can present in the form of trigger points, fibromyositis, myositis, muscle spasm, and muscle weakness. The purpose of this study is to research for quantifiable physiological differences between groups of normal subjects and myofascial pain dysfunction (MPD) patients. The first specific aim was to determine the opening of the jaw at which maximal isometric tension can be produced by the jaw closing muscles, with the hypothesis that this opening of maximal tension would be less for a group of MPD patients than for a group of normal subjects being tested. The second aim was to test the hypothesis that the maximal isometric bite forces for the two groups would differ. Patients with mandibular dysfunction are reported to have a lower maximal bite than normal subjects. Bite force was measured with the T-Scan system. An 80 micron horseshoe-shaped sensor connected to a dedicated IBM XT computer recorded the data. A self-contained printer produced the hard copy for later analysis. Vertical dimension or jaw opening was increased in 0.5-mm increments using double flat plane appliances standardized by the Relator. A MANOVA was used for statistical analysis of the data. MPD patients had significantly higher bite forces at 8.0, 8.5, 9, and 9.5 mm. Normal subjects had higher force values at 5.0 mm. There was no significant difference in mean maximal bite force between groups.

Facial thermography, basis, protocol, and clinical value.

Computerized electronic telethermography provides clinicians with a reliable evaluation of subtle body surface temperature changes that show underlying physical disorders characterized by pain. The first study population involved 4000 measurements of 100 volunteers at the Medical School of New Jersey. This study of normal volunteers evaluates the validity and reliability of using 0.5 degrees C skin surface temperature difference between opposite sides of the head as a minimum difference standard for recognition of a clinically significant thermographic abnormality. A second study population of over 300 patients with clinically suspected temporomandibular disorder were used. The authors used a standard thermographic protocol procedure that is approved by the Academy of Neuromuscular Thermography. Also discussed in detail are artifactual influences and trigger point detection. The clinical value of this information in the diagnosis and treatment of temporomandibular disorder patients is self evident.

Video display terminal operation: a potential risk in the etiology and maintenance of temporomandibular disorders.

Surveys indicate over 50 million Americans, mostly women, currently operate video display terminals (VDTs) at home or in the workplace. Recent epidemiological studies reveal more than 75% of approximately 30 million American temporomandibular disorder (TMD) sufferers are women. What does the VDT and TMD have in common besides an affinity for the female gender? TMD is associated with numerous risk factors that commonly initiate sympathetic nervous system and stress hormone response mechanisms resulting in muscle spasms, trigger point formation, and pain in the head and neck. Likewise VDT operation may be linked to three additional sympathetic nervous system irritants including: (1) electrostatic ambient air negative ion depletion, (2) electromagnetic radiation, and (3) eyestrain and postural stress associated with poor work habits and improper work station design. Additional research considering the roles these three factors may play in the etiology of TMD and other myofascial pain problems is indicated. Furthermore, dentists are advised to educate patients as to these possible risks, encourage preventive behaviors on the part of employers and employees, and recommend workplace health, safety, and ergonomic upgrades when indicated.

Temporomandibular-related pressure thresholds: a model for establishing baselines.

The use of pressure threshold measurement to quantify tender spots and trigger points in muscles is well established. Its application to the field of temporomandibular disorders, however, has been more recent and less widely published. Pressure threshold measurement may be useful to define values for dysfunctional muscles or structures so that changes in muscle condition through a course of treatment can be quantified. Normal values for many muscles in the body have been established, but studies of this type in the masticatory system are limited and have often used a fixed, pre-determined pressure cutoff, rather than measuring thresholds across a number of patients. This pilot study seeks to determine whether normal values exist for the anterior temporalis muscles, the masseter muscles, and the lateral capsules of the temporomandibular joints. Intrarater and interrater reliability in measuring thresholds was also studied with the aim of contributing toward a methodological model for further study.

The craniocervical connection: a retrospective analysis of 300 whiplash patients with cervical and temporomandibular disorders.

Because the concept of whiplash as a causative factor for temporomandibular disorders (TMD) is highly controversial, we decided to do a retrospective analysis of patients treated in our office who had sustained whiplash injuries and were treated for cervical and temporomandibular disorders. The records of 300 patients with TMD preceded by a motor vehicle accident were examined retrospectively. The most common presenting symptoms, in order, were: jaw pain, neck pain, post-traumatic headache, jaw fatigue, and severe temporomandibular joint (TMJ) clicking. The most common TMD diagnoses were: masseter trigger points, closing jaw muscle hyperactivity, TMJ synovitis, opening jaw muscle hyperactivity, and advanced TMJ disk derangement. Based primarily on the physical examination, we concluded that the TMJ and surrounding musculature should be examined similarly to other joints, with no preconceived notion that TMD pathology after whiplash is unlikely.

Non-pharmacologic management of sickle cell pain.

Patients with sickle cell disease (SCD) suffer from both acute and chronic pain. The latter includes avascular necrosis of the hip joints mostly in the adult population. It has a negative impact on the quality of life of affected individuals and is often associated with depression, disability, unemployment and dependence on opioid analgesics. In this study, we show that a non-pharmacologic approach to management with deep tissue/deep pressure massage therapy technique, including neuromuscular trigger point treatment with acupressure, in patients with SCD has a salutary effect on pain relief and quality of life.

The effect of an ergonomic intervention on musculoskeletal, psychosocial, and visual strain of VDT data entry work: the United States part of the international study.

The United States MEPS (musculoskeletal--eyestrain--psychosocial--stress) study consisted of 1 group of 28 female data entry operators. The intervention was in 3 parts: workstation redesign (including advanced ergonomic chairs, motorized adjustable workstations, advanced adjustable keyboards, adjustable copyholders, adjustable footrests, monitor support surfaces) and ergonomic training/coaching and corrective lenses. After the intervention, statistically significant reductions in physical signs (trigger points, neck and shoulder mobility), subjective reports of intensity and frequency of musculoskeletal pain, and subjective reports of visual problems were observed. Static load during the work sample, as assessed by experts, improved after the intervention as did measured postural angles of head and trunk and subjective assessment of users of ergonomic characteristics of the workplaces. For all of these measures, improvements observed 1 month after intervention were also observed in the 1-year follow-up. Trapezius load, as assessed by electromyography (EMG), decreased after intervention, but then increased in the follow-up. The increase was interpreted as a calibration problem.

Does botulinum toxin A make prosthesis use easier for amputees?

Four post-amputation patients (1 with phantom pain, 3 with stump pain) were each treated with 100 IU botulinum toxin A, divided between several trigger points in the distal stump musculature. In 1 female patient (along with a pronounced reduction in phantom pain) hyperhidrosis of the stump ceased completely, probably after diffusion of the drug into the dermal sweat glands, leading to longer and safer use of the prosthesis. Intentional intradermal injection for this issue therefore could be valuable. Another patient was able to use her prosthesis for the whole day again after botulinum toxin A treatment for substantial stump pain, compared with only 4 hours a day before treatment. In 2 male patients, stump pain while wearing the prosthesis subsided to a considerable extent, 1 of the 2 reported an improvement in steadiness of gait. We suggest that stump treatment with botulinum toxin in rehabilitative medicine should be investigated in more detail.

Issues in planning a placebo-controlled trial of manual methods: results of a pilot study.

OBJECTIVE: There are fundamental differences between the administration of medications and the application of manual procedures, such as those used by chiropractors. The objective of this study was to gather preliminary information on how to address these differences in the design of a multisite, randomized placebo-controlled trial of chiropractic care for women with chronic pelvic pain (CPP). DESIGN: Pilot study for a multisite, randomized, placebo-controlled clinical trial. SETTING: Three chiropractic research clinics in the midwest United States. SUBJECTS: Thirty-nine (39) women with CPP of at least 6 months' duration, diagnosed by board-certified gynecologists. INTERVENTIONS: The active intervention consisted of the chiropractic technique, lumbar spine flexion-distraction, combined with manual Trigger Point Therapy. The placebo intervention consisted of a sham chiropractic procedure performed with an instrument combined with effleurage (light massage). OUTCOME MEASURES: The primary outcome measure was the change in the Pain Disability Index (PDI) from baseline to the end of treatment (6 weeks), assessed by group and site. If the change score was in the same direction at all sites, the results were to be combined to estimate treatment effect size. RESULTS: Patient characteristics were similar to those of patients with CPP in other studies. Recruitment methods, particularly in respect to the eligibility criteria and screening protocols, would require modification in order to recruit an adequate sample for the planned randomized controlled trial. Clinicians followed standardized procedures with apparently minimal deviation, patients in both groups were satisfied with their care and blinding appeared to be successful. PDI change scores were not consistent across sites and so results were not combined and overall treatment effect sizes were not estimated. CONCLUSIONS: The technical and personnel resources required to achieve adequate standardization of procedures at multiple sites may make a placebo-controlled trial unfeasible, given our current lack of knowledge about the active agent in manual chiropractic procedures.

Neural therapy in the treatment of multiple sclerosis.

OBJECTIVE: To assess the therapeutic potential of neural therapy, a modified form of acupuncture, in multiple sclerosis. DESIGN: A pilot study followed by a double-blind, placebo-controlled randomized study. SETTING: The Glasgow Homoeopathic Hospital, Glasgow, Scotland. PATIENTS: An unselected group of 61 new patients referred to the Glasgow Homoeopathic Hospital, suffering from any type of multiple sclerosis, who fulfilled the criteria of Schumacher and had a Disability Status Score (DSS) or Expanded Disability Status Score (EDSS) grade of 1-7. INTERVENTION: Neural therapy, which is the injection of small amounts of local anesthetic without adrenaline, into specific trigger points in the ankles and around the greatest circumference of the skull. MAIN OUTCOME MEASURES: Improvements in the Kurtzke scales and the DSS or EDSS assessments. RESULTS: Sixty-five percent (65%) of the patients in the pilot study (n = 40) and seventy-six percent (76%) of the patients in the double-blind trial (n = 21) benefitted from this treatment as assessed by Kurtzke scale improvements. On long-term follow-up of 2.0 to 3.5 years, more than 50% of the patients continued to show improved Kurtzke scale ratings. Improvements could be rapid. No toxic side effects were noted when injections were administered at a frequency of once or twice weekly or less. CONCLUSIONS: Neural therapy is an effective, nontoxic and inexpensive treatment for multiple sclerosis that can confer both immediate and long-term benefits.
