The practice of physical medicine and rehabilitation in subSaharan Africa and Antarctica: a white paper or a black mark?

AIM: The medical specialty of physical medicine and rehabilitation (PM&R) has had a proven impact on persons with disability and on healthcare systems. Documents such as The White Book on Physical and Rehabilitation Medicine in Europe have been important in defining the scope of practice within various regions. However on some continents the practice has not been well defined. The aim of this paper was to explore the practice of PM&R in subSaharan Africa and Antarctica. METHODS: Medline searches, membership data searches, fax survey of medical schools, Internet searches, and interviews with experts. RESULTS: The continents are dissimilar in terms of climate and government; However, both Antarctica and subSaharan Africa have no PM&R training programs, no professional organizations, no specialty board requirements, and no practicing physicians in the field. Since there are no known disabled children on Antarctica and adults are airlifted to world-class health care, the consequences of this deficit are minimal there. However the 788,000,000 permanent residents of subSaharan Africa including approximately 78 million persons with disability are left unserved. CONCLUSIONS: Antarctica is doing fine. Africa is in a crisis. Local medical schools, hospitals doctors, and persons with disability; along with foreign volunteers, aid groups, and policymakers can impact the crisis. However government specifically national ministries of health is ultimately responsible for the health and wellbeing of citizens.

Epidemiology of spinal cord injuries in the 2005 Pakistan earthquake.

STUDY DESIGN: Prospective observational study. OBJECTIVES: To identify the epidemiological features specific to spinal injuries as a result of an earthquake. SETTINGS: Rawalpindi, Pakistan in the months after the 8 October 2005 earthquake. METHODS: In the month after the earthquake, the one established rehabilitation center was augmented with two makeshift spinal cord centers. Information on mechanism of injury, mode of evacuation, associated injuries was gathered, and a detailed clinical and radiological assessment was performed. Neurological status and functional outcome was determined after 10 weeks. RESULTS: Of an estimated 650-750 spinal cord injuries, 187 were admitted to these centers, including 80 men and 107 women with a mean age of 28.3+/-12.4 years. Injuries occurred while standing in 57.8% of patients. Most (83.4%) who reached the spinal cord center were airlifted. A urinary catheter had been placed before admission in 91.5%. Most of the patients were paraplegic 89.3, with 50.8% incomplete injuries. Fracture or fracture dislocation was present in 70, and 75% underwent spinal fixation. Although pressure ulcers (28.9%) and urinary tract infections (39%) were common, deep venous thromboses (4.8%) and depression (5.8%) were seldom detected. At 10 weeks, 75% were continent or performing intermittent catheterization. There were no deaths and two births. CONCLUSION: After a disaster, evacuation of persons with a spinal cord injury to a specialized center results in low mortality. Response planning for disasters should include early aggressive medical rehabilitation.

Effects of low back disability status on lower back discomfort during sustained and cyclical trunk flexion.

A laboratory study was conducted to determine the effects of back disability status on endurance time and perceived discomfort during trunk flexion. Eighty participants (40 with chronic or recurrent low back pain (CRLBP), 40 pain-free) were tested. The trunk was flexed to 15 degrees, 30 degrees, 45 degrees and 60 degrees under three conditions: 1) continuous static flexion; 2) cyclical flexion with 20% rest; and 3) cyclical flexion with 40% rest. Each condition was performed for up to 600 s or until the participant reached his/her pain tolerance limit. Dependent variables included time to distracting discomfort (TDD), total endurance time (TET) and perceived discomfort. For continuous exertions, CRLBP participants had lower TDD (p < 0.001), lower TET (p < 0.001) and greater discomfort (p < 0.001) compared to pain-free controls. In both groups, TDD and TET decreased and perceived discomfort increased as the flexion angle increased. For intermittent exertions, CRLBP participants reported greater discomfort than pain-free participants (p < 0.001). Increasing rest from 20 to 40% reduced discomfort in CRLBP participants, but produced no consistent benefit in pain-free participants. To accommodate persons with CRLBP, consideration should be given to reducing both the magnitude (angle) and duration of trunk flexion required by their jobs.

Relationship between ambulation and obesity in older persons with and without low back pain.

CONTEXT: For obese older persons, ambulation is both functionally important and a means of weight control. The relationship between weight and ambulation is not known in this population. Also, the extent to which pain interferes with ambulation is not studied. OBJECTIVE: To examine the relationship between obesity and ambulation, and to determine the effect of pain and body mass index (BMI) on ambulation in older persons. DESIGN, SETTING, AND PARTICIPANTS: Retrospective study of 82 older persons, ages 55-79 y, some with no back pain recruited from the community, others with back pain or spinal stenosis recruited from a magnetic resonance imaging (MRI) scanner as part of a larger university study of spinal stenosis. OUTCOME MEASURES: Age, Visual Analog Scales for pain, BMI, patient diagnosis (no pain, mechanical back pain, and spinal stenosis), walking velocity and stride length on a 15-min laboratory ambulation test, and 1-week community ambulation measured with a pedometer (steps, distance, and energy expenditure). RESULTS: BMI had a significant inverse relationship with ambulatory measurements in terms of the distance walked, steps taken, and walking velocity. Pain severity and pain category also had a significant inverse relationship with these measures. A negative correlation was observed between pain and obesity, although the relationship was statistically nonsignificant. DISCUSSION: Obese older people walked less than the nonobese older people. Pain was associated with decreased ambulation. Clinicians who intend to encourage increased ambulation in older obese persons should consider possible barriers posed by musculoskeletal pain.

Functional capacity evaluations in persons with spinal disorders: predicting poor outcomes on the Functional Assessment Screening Test (FAST).

This study determines how performance on the simple, low exertion Functional Assessment Screening Test (FAST) relates to performance on more extensive physical and psychological testing. One hundred eighty-eight persons with chronic back disability and 17 spine healthy volunteers underwent the FAST (three 2-min static tests [kneeling, stooping, and squatting] and two 5-min tests [repetitive stooping and repetitive twisting while standing]), the Progressive Isoinertial Lifting Evaluation (PILE), trunk extension endurance, submaximal bicycle ergometry, and psychological profiles. All FAST components were completed by 88% of spine healthy subjects, but only by 19.7% (n = 37) of the back patients. Internal consistency for overall test performance was 0.82 (alpha coefficient). Back pain noncompleters had poorer performance on the PILE and trunk extension endurance despite similar cardiovascular fitness and perceived exertion during testing. They had more dysfunctional coping mechanisms, pain avoidance, depression, and self-reported disability. Since performance on nonstrenuous testing is so poor, and psychosocial variables relate strongly to test performance, extensive Functional Capacity Evaluations may not be necessary or valid in assessing the physical performance of this population of chronic back pain patients.

Multidisciplinary team evaluation of upper extremity injuries in a single visit: the UPPER Program.

Musculoskeletal disorders are the leading cause of disability among people between 18 and 64 years of age. Patients with musculoskeletal injuries of the upper extremities are usually evaluated and treated by an individual physician and therapist. However, for patients who have problems, especially after being treated by a hand surgeon and a certified hand therapist, there are few other management options. A multidisciplinary assessment program for patients with chronic upper limb pain has not been described in the literature. As part of The University of Michigan RERC (Rehabilitation Engineering Research Center), the UPPER Program (UPper extremity Protocol Evaluation in Rehabilitation) was developed to evaluate patients who have disabling upper limb musculoskeletal disorders. At the center of the program is a multidisciplinary team composed of a physiatrist (physical medicine and rehabilitation specialist), occupational therapist, physical therapist, exercise physiologist, vocational counselor and pain psychologist. The UPPER Program elements include a pre-evaluation questionnaire, individual team member assessments and a team meeting. It is followed by a patient appointment with the team physician to review the results and recommendations. The essential details of the program are presented in this article so it can be reproduced elsewhere.

Insurance case managers' perception of quality in back pain programs: a focus study group.

OBJECTIVES: Insurance case managers commonly interact with physiatrists and rehabilitation programs. They influence referrals and patients' decision making. This study was designed to determine which factors affect case managers' perception of back pain program quality. DESIGN: Repeated focus group interview in a neutral facility in an urban Midwestern United States community. Subjects were two groups (n = 12 and 11) of insurance case managers employed by case management firms (large and small), insurers, and self-insured employers. Outcome measures included group and individual responses to a pre-scripted interview and were collected on tape, transcribed, and interpreted by two different persons: the independent expert interviewer and a pain psychologist. RESULTS: There was substantial agreement between the two interpreters. Both groups overwhelmingly chose physiatrists over other specialists. They emphasized timeliness, communication, functionally oriented programs, concrete program goals and time frames, physician knowledge of the legal aspects of disability, and rapid communication of patient noncompliance. CONCLUSIONS: Rehabilitation programs may strive to meet many of these qualities but, in doing so, should be aware that the legal and ethical roles of case managers differ from that of clinicians.

Baastrup's disease correlating with diffuse lumbar paraspinal atrophy: a case report.

Baastrup's disease ("kissing spine") is an x-ray finding that has been considered a possible cause of low back pain (LBP) since the 1930s. Its etiology is unknown, and there are no reports of muscle or soft tissue changes associated with it. This case report concerns a 57-year-old man with chronic LBP, stiffness, and indurated skin over the back. He had classic sclerotic changes between the spinous processes on x-ray, which is consistent with Baastrup's disease. Computed tomography (CT) and electromyography were performed. CT showed profound fatty replacement of the paraspinal musculature. An electromyography report showed severe isolated paraspinal denervation. This case suggests that diffuse fatty replacement of the paraspinal muscles, perhaps due to a compartment syndrome or other vascular event, may have a role in the pathogenesis of Baastrup's disease.

An objective review of consumer books about back pain.

Back pain is epidemic, and dozens of books inform the public about this disorder. The increase in "self-help" medical books has not been accompanied by objective critiques of this important literature. We conducted an objective, quantified evaluation of the comprehensiveness and quality of these books. A Books in Print search resulted in 38 books on back pain, of which 27 were found and purchased. Topics covered, organization, and emphasis were coded according to scales with excellent interrater reliability. Alternative and conventional treatments were emphasized in most books, but epidemiology, natural history, and risk factors were substantially de-emphasized, covering less than 3% of the text. This objective and validated evaluation of the consumer literature provides a format for researching patient education in other health areas.

Paraspinal electromyography in high lumbar and thoracic lesions.

OBJECTIVE: To use needle electromyography in the paraspinal muscles to localize the root level of a radiculopathy. DESIGN: We collected nine cases of clinically proven, isolated high lumbar or thoracic disk herniations of patients who underwent MiniPM. Four were from a prospective study of 114 persons with low back pain (MiniPM had 100% sensitivity to magnetic resonance imaging-documented high disks). RESULTS: In the most medial "S" column, mean MiniPM scores were 0.7 for the level above the radiologically documented lesion; 3.1 at the lesion; and 1.6, 1.6, and 1.1 at the three spinous processes below the lesion. Similar numbers were obtained in the "M" column (slightly lateral), with no significant differences between S and M. Differences were significant between and at the level of the lesion for S (P < 0.06) and M (P < 0.01), and between the lesion level and three levels below for the M column (P < 0.01). CONCLUSIONS: These findings suggest that paraspinal electromyography has a higher than previously reported sensitivity for high lumbar lesions. Electromyography using MiniPM can localize some radiculopathies. The individual cases suggest that, consistent with the anatomy of the caudi equina, thoracic lesions and lateral lumbar lesions denervate only at one level, but more central lumbar lesions also denervate distally innervated paraspinal muscles.

Describing paraspinal EMG findings: inadequacy of the single 0-4+ score.

OBJECTIVE: Clinical electrodiagnostic textbooks instruct that lumbar radiculopathies typically have paraspinal abnormalities and that these abnormalities should be recorded using a single 0-4+ scale. Recent work demonstrates that that the innervation of the paraspinal muscles is segmental, not homogenous, and that asymptomatic persons may have reproducible ("1+") positive waves or fibrillation potentials. DESIGN: To assess current use of the 0-4+ scale, a retrospective study of EMG scores in persons diagnosed with radiculopathy at a university laboratory was performed. No specific paraspinal EMG technique was used. Included were 117 consecutive, qualified S-1 radiculopathies and 33 L-5 radiculopathies. RESULTS: When radiculopathy was defined by "more than one limb muscle abnormal," paraspinal scores were recorded as 0 to 1+ in 83% of L-5 and 63% of S-1 cases (chi2, L-5 vs. S-1, not significant). For more severe radiculopathies (at least one limb muscle with a "2+" score), 0-1+ paraspinal scores were recorded in 76% of L-5 and 57% of S-1 cases (chi2, not significant). A total of 82% of S-1 radiculopathies with no overlapping L-5 innervation had 0-1+ scores. CONCLUSIONS: These data demonstrate the common use of equivocal paraspinal scores in patients whom electromyographers believe have radiculopathies. Standardized exploration techniques and a more detailed scoring system for the paraspinal muscles may eliminate this discrepancy.

The value of electrodiagnostic consultation for patients with upper extremity nerve complaints: a prospective comparison with the history and physical examination.

OBJECTIVES: To determine whether electrodiagnostic testing changes diagnostic certainty compared with a detailed history and physical examination, and whether interactions between medical information, the extent of testing, and diagnostic certainty imply a need for advanced medical knowledge on the part of the tester. DESIGN: Prospective observation. SETTING: University orthopedic department and small community hospital electrodiagnostic laboratories. PATIENTS: Two hundred fifty-five consecutive referrals for upper extremity nerve complaints. OUTCOME MEASURES: Diagnosis, diagnostic confidence, and severity of neurologic lesion were coded after standardized history and physical and after electrodiagnostic testing. RESULTS: Electrodiagnostic testing substantially altered 42% of diagnoses, confirmed 37%, and did not clarify 21%. The extent of testing correlated with the size of the differential diagnosis, the number of previous hospitalizations, and the number of other medical problems. Confidence in final diagnoses correlated positively with severity of the lesion, but negatively with the size of the differential diagnosis and the number of painful body areas. Hospitalizations and medical problems also tended towards negative correlations. CONCLUSIONS: This study, in which all electrodiagnostics, histories, and physical examinations were performed by a single physician, suggests that electrodiagnosis substantially alters clinical impressions in a large percentage of patients. The complex relationship between clinical information, the extent of testing, and final diagnostic certainty suggests that specialized medical knowledge is required for accurate electrodiagnosis.
