A Conversation Between Past and Present Chairs of the American Board of Physical Medicine and Rehabilitation: Four Decades of History and the Future of Board Certification.

ABSTRACT: On the 75th anniversary of the founding of the American Board of Physical Medicine and Rehabilitation, 11 of the surviving chairs of the board convened virtually to reflect on the past 40 years of major trends for the accrediting body of physiatrists. The field rapidly expanded in the 1980s, driven by changes in the reimbursement environment. This rapid expansion drove an improvement in the caliber of residents choosing the field and in the quality of training programs. As physical medicine and rehabilitation evolved from a small- to medium-sized specialty, the board addressed many challenges: securing a credible position within the American Board of Medical Specialties; addressing a rising demand for subspecialty certification; improving training and exposure to physiatry; enhancing the quality of the accreditation process; and reducing the burden of accreditation on diplomates. The future development of physiatry includes improving diversity, equity, and inclusion, while restoring provider morale, well-being, and meaningfulness in work. Although challenges remain, physiatry as a field has grown to be well established through the board's efforts and respected within the larger medical community.

Spinal cord injured women's treatment of breast carcinoma: alert to complications.

INTRODUCTION: Women with spinal cord injury (SCI) and who develop breast cancer are a vulnerable and potentially overlooked population. They experience risk factors owing to decreased mobility and are at risk for unique complications from their oncologic treatment. CASE PRESENTATION: A 54-year-old woman who suffered a T6 AIS A traumatic SCI in 1981, who was diagnosed 32 years later with estrogen receptor and progesterone receptor positive and human epidermal growth factor receptor 2-negative invasive ductal carcinoma. During the course of her chemotherapy, she experienced several complications, including reflexive diaphoresis, urinary tract infection, leukopenia, anemia, dehydration, and weakness. These contributed to the development of a stage 4 ischial pressure sore, which required complex treatment. DISCUSSION: There is a paucity of literature examining the complications of chemotherapy that may be unique to those with SCI. Physiatrists will be seeing more women undergoing oncologic care, as this population of patients ages. A multidisciplinary approach that takes into account the pathophysiologic changes associated with SCI is crucial to understand and prevent complications that could affect their outcomes and contribute to increased cost in a value-based health-care system.

Linking spinal cord injury rehabilitation between the World Wars: The R. Tait McKenzie legacy.

Spinal cord injury (SCI) medicine emerged after World War II due to mass casualties, which required specialized treatment centers. This approach to categorical care, however, was first developed during World War I, led by pioneers R. Tait McKenzie and George Deaver, who demonstrated that soldiers disabled by paralysis could return to society through fitness/mobility, recreational and vocational training. McKenzie, a Canadian and the first professor of physical therapy in the US, influenced Deaver and military physicians in Britain, Canada, and the U.S. with his achievements and publications. Although early mortality from SCI was high, advances in the treatment of skin and bladder complications coupled with rehabilitation developed through lessons learned in World War I, resulted in major changes in survival and quality of life for veterans of World War II in England, US, and Canada. Harry Botterell and Al Jousse, founders of Lyndhurst Lodge, the first SCI center in Canada, adopted Deaver's principles and techniques of rehabilitation and Donald Munro's approach to medical complications. The consequences of failing to organize continuity of care in World War I were recognized both by consumers and physicians. Together with John Counsell, a World War II veteran, they formed the Canadian Paraplegic Association, which "revolutionized" the care of veterans with SCI, as well as civilians, women, and children.

Franklin Delano Roosevelt: The Diagnosis of Poliomyelitis Revisited.

Revisiting the ailments of famous historical persons in light of contemporary medical understanding has become a common academic hobby. Public discussion of Franklin Delano Roosevelt's (FDR) diagnosis of poliomyelitis after his sudden onset of paralysis in 1921 has received just such a revisitation. Recently, this 2003 historical analysis has been referenced widely on the Internet and in biographies, raising speculation that his actual diagnosis should have been Guillain-Barré Syndrome, a noncontagious disease of the peripheral nervous system rather than poliomyelitis. The authors of that 2003 analysis used a statistical analysis of his case by selectively choosing some of his reported symptoms. FDR's diagnosis of poliomyelitis, however, was fully supported by the findings of leading expert physicians of that time, who were very knowledgeable in the then-common disease and who periodically examined him during the period of 1921-1924. The most significant diagnostic features of polio are the absence of objective sensory findings in the presence of flaccid motor paralysis. These features are consistent with diagnostic criteria extant during the periods of major poliomyelitis epidemics as well as those of the Center for Disease Control 90 years later. Additional findings of fever, prodromal hyperesthesia, more severe residual proximal muscle weakness, and extensive lower extremity impairment requiring mobility with long leg braces or a wheelchair give further evidence for the diagnosis in FDR's case. Nonbulbar Guillain-Barré Syndrome, which shares the features of a flaccid paralysis and thus mimicking the initial presentation of poliomyelitis, has more than an 80% complete recovery with no reported cases of eventual wheelchair use. The most severe cases of Guillain-Barré Syndrome often have persistent objective sensory loss, associated with greater weakness in the feet and hands, which show no resemblance to FDR's impairment and disability. In light of the expert initial assessments by physicians completely familiar with the signs and symptoms of the then-common disease, review of his initial and subsequent disease course, and residual symptoms in comparison with those of Guillain-Barré syndrome, we find no reason to question the diagnostic accuracy of poliomyelitis and wish to put this debate to rest.

Influence of Age Alone, and Age Combined With Pinprick, on Recovery of Walking Function in Motor Complete, Sensory Incomplete Spinal Cord Injury.

OBJECTIVE: To determine if age, pinprick scores in the lower extremities, and neurologic severity of injury influence recovery of ambulation in persons with motor complete, sensory incomplete (American Spinal Injury Association Impairment Scale [AIS] grade B) spinal cord injury (SCI) 1 year after initial injury. DESIGN: This retrospective analysis examined subjects with AIS grade B from the Spinal Cord Injury Model System (SCIMS) database from 2006 to 2015. The baseline neurologic examination at rehabilitation admission (2-4wk postinjury) was used for comparison with 1-year outcome measures of locomotion. SETTING: Fifteen acute inpatient rehabilitation centers (participants in the SCIMS database). PARTICIPANTS: Participants with AIS grade B SCI (N=249) were enrolled in the SCIMS database in 2 cycles (2006-2010 and 2011-2015). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Household ambulation at 1 year by FONE-FIM and by direct interview, as part of the annual neurologic exam; change in American Spinal Injury Association score 1 year postinjury. RESULTS: Findings demonstrate a statistically nonsignificant increase in likelihood of walking for those age <50 years compared with those age ≥50 years (relative risk [RR]=1.99; 95% confidence interval, 0.80-3.04). Presence of pinprick in at least one half of the lower-extremity dermatomes L2-S1 was associated with higher likelihood of walking (RR=5.57, P=.0023). Pinprick was significant for patients age <50 years (RR=4.58, P=.0090) but not for those age ≥50 years (P=.15). CONCLUSIONS: Compared with younger individuals, participants age ≥50 years with AIS grade B SCI are less likely to achieve walking function 1 year postinjury. Likewise, preservation of pinprick sensation postinjury in the majority of lower-extremity dermatomes L2-S1 increases the chances of walking in individuals age <50 years.

Advances in the rehabilitation management of acute spinal cord injury.

Aggressive assessment and management of the secondary complications in the hours and days following spinal cord injury (SCI) leads to restoration of function in patients through intervention by a team of rehabilitation professionals. The recent certification of SCI physicians, newly validated assessments of impairment and function measures, and international databases agreed upon by SCI experts should lead to documentation of improved rehabilitation care. This chapter highlights recent advances in assessment and treatment based on evidence-based classification of literature reviews and expert opinion in the acute phase of SCI. A number of these reviews are the product of the Consortium for Spinal Cord Medicine, which offers clinical practice guidelines for healthcare professionals. Recognition of and early intervention for problems such as bradycardia, orthostatic hypotension, deep vein thrombosis/pulmonary embolism, and early ventilatory failure will be addressed although other chapters may discuss some issues in greater detail. Early assessment and intervention for neurogenic bladder and bowel function has proven effective in the prevention of renal failure and uncontrolled incontinence. Attention to overuse and disuse with training and advanced technology such as functional electrical stimulation have reduced pain and disability associated with upper extremity deterioration and improved physical fitness. Topics such as chronic pain, spasticity, sexual dysfunction, and pressure sores will be covered in more detail in additional chapters. However, the comprehensive and integrated rehabilitation by specialized SCI teams of physicians, nurses, therapists, social workers, and psychologists immediately following SCI has become the standard of care throughout the world.

A clinical prediction rule for ambulation outcomes after traumatic spinal cord injury: a longitudinal cohort study.

BACKGROUND: Traumatic spinal cord injury is a serious disorder in which early prediction of ambulation is important to counsel patients and to plan rehabilitation. We developed a reliable, validated prediction rule to assess a patient's chances of walking independently after such injury. METHODS: We undertook a longitudinal cohort study of adult patients with traumatic spinal cord injury, with early (within the first 15 days after injury) and late (1-year follow-up) clinical examinations, who were admitted to one of 19 European centres between July, 2001, and June, 2008. A clinical prediction rule based on age and neurological variables was derived from the international standards for neurological classification of spinal cord injury with a multivariate logistic regression model. Primary outcome measure 1 year after injury was independent indoor walking based on the Spinal Cord Independence Measure. Model performances were quantified with respect to discrimination (area under receiver-operating-characteristics curve [AUC]). Temporal validation was done in a second group of patients from July, 2008, to December, 2009. FINDINGS: Of 1442 patients with spinal cord injury, 492 had available outcome measures. A combination of age (<65 vs ≥65 years), motor scores of the quadriceps femoris (L3), gastrocsoleus (S1) muscles, and light touch sensation of dermatomes L3 and S1 showed excellent discrimination in distinguishing independent walkers from dependent walkers and non-walkers (AUC 0·956, 95% CI 0·936-0·976, p<0·0001). Temporal validation in 99 patients confirmed excellent discriminating ability of the prediction rule (AUC 0·967, 0·939-0·995, p<0·0001). INTERPRETATION: Our prediction rule, including age and four neurological tests, can give an early prognosis of an individual's ability to walk after traumatic spinal cord injury, which can be used to set rehabilitation goals and might improve the ability to stratify patients in interventional trials.

The reproducibility and convergent validity of the walking index for spinal cord injury (WISCI) in chronic spinal cord injury.

BACKGROUND: The Walking Index for Spinal Cord Injury II (WISCI II) is a hierarchical scale that measures improvements in walking following spinal cord injury (SCI). The WISCI II has good face validity, concurrent validity, and reliability following acute SCI; however, psychometric properties need to be determined for chronic SCI. Because prior studies have demonstrated a relationship between lower-extremity motor scores (LEMS) and walking, outcome measures for walking should demonstrate a linkage between the underlying impairment (weakness) and walking-convergent validity. OBJECTIVE: To determine convergent validity and reproducibility of the WISCI II. METHODS: Self-selected and maximum WISCI levels were assessed for 76 patients with chronic SCI (34 paraplegia, 42 tetraplegia); 10-m walking speeds were calculated. Convergent validity was assessed by correlating WISCI II levels to LEMS and walking speed. Reproducibility was assessed with the intraclass correlation coefficient (ICC) and the smallest real difference (SRD). RESULTS: Convergent validity of the self-selected and maximum WISCI II with LEMS was moderate for paraplegia (ρ = 0.479 and ρ = 0.533) and strong for tetraplegia (ρ = 0.852 and ρ = 0.816). Tetraplegia, but not paraplegia, demonstrated convergent validity of walking speed at the self-selected and maximum WISCI levels with LEMS (ρ = 0.752 and ρ = 0.813). WISCI reproducibility was excellent (self-selected ICC = 0.994; maximum ICC = 0.995), resulting in SRDs of 0.785 (self-selected) and 0.597 (maximum), suggesting that a change of one WISCI level can be interpreted as real in a chronic patient. CONCLUSIONS: Results suggest that the WISCI II should be a very useful outcome measure for detecting changes in walking function following chronic SCI.

Outcome measures for gait and ambulation in the spinal cord injury population.

BACKGROUND: At the 2006 National Institute on Disability and Rehabilitation Research (NIDRR) sponsored pre-conference on spinal cord injury (SCI) outcomes, several gait and ambulation measures were evaluated for utility in clinical practice, validity, and reliability as research measurement tools. The Conference Subcommittee on Gait and Ambulation chose to review the Walking Index for Spinal Cord Injury II (WISCI II), 50-Foot Walk Test (50FTWT), 6-Minute Walk Test (6MWT), 10-Meter Walk Test (10MWT), and Functional Independence Measure-Locomotor (FIM-L). METHODS: A subcommittee of international experts evaluated each instrument for test construct, administration, population applicability, reliability, sensitivity to change, and validity. Evaluations for each outcome measure were compiled, distributed to the whole committee, and then further reviewed with addition of comments and recommendations for consensus. An audience of experts voted on the validity and usefulness of each measure. RESULTS: WISCI II and 10MWT were found to be the most valid and clinically useful tests to measure improvement in gait for patients with SCI. FIM-L had little utility and validity for research in SCI. 6MWT and 50FTWT were found to be useful but in need of further validation or changes for the SCI population. CONCLUSION: A combination of the 10MWT and WISCI II would provide the most valid measure of improvement in gait and ambulation in as much as objective changes of speed, and functional capacity allow for interval measurement. To provide the most comprehensive battery, however, it will be important to include a measure of endurance such as the 6MWT. Further validation and study should be devoted to WISCI II, 10MWT, and 6MWT as primary outcome measures for gait in SCI.

Validity of the walking scale for spinal cord injury and other domains of function in a multicenter clinical trial.

OBJECTIVE: To demonstrate criterion (concurrent and predictive) and construct validity of the Walking Index for Spinal Cord Injury (WISCI) scale and other walking measures in the Spinal Cord Injury Locomotor Trial (SCILT). DESIGN: Prospective multicenter clinical trial of a walking intervention for patients with acute traumatic spinal cord injury (SCI). PARTICIPANTS/ METHODS: Body weight-supported treadmill training was compared to overground mobility training in 146 patients with incomplete SCI (C4 to L3) enrolled within 8 weeks of onset and treated for 12 weeks. Primary outcome measures were the Functional Independence Measure (FIM), 50-foot walking speed (50FW-S), and 6-minute walking distance (6MW-D), tested 3, 6, and 12 months after entry. Secondary measures were the Lower Extremity Motor Score (LEMS), Berg Balance Scale (BBS), WISCI, and FIM locomotor score (LFIM), assessed at 6 centers by blinded observers. Data for the 2 arms were combined since no significant differences in outcomes had been found. RESULTS: Correlations with WISCI at 6 months were significant with BBS (r = .90), LEMS (r = .85), LFIM (r = .89), FIM (r = .77), 50FW-S (r = .85), and 6MW-D ( r = .79); similar correlations occurred at 3 and 12 months. Correlations of change scores from baseline WISCI were significant for change scores from baseline of LEMS/BBS/LFIM. Correlation of baseline LEMS and WISCI at 12 months were most significant (r = .73). The R(2) of baseline LEMS explained 57% of variability of WISCI levels at 3 months. CONCLUSION: Concurrent validity of the WISCI scale was supported by significant correlations with all measures at 3, 6, and 12 months. Correlation of change scores supports predictive validity. The LEMS at baseline was the best predictor of the WISCI score at 12 months and explained most of the variance, which supported both predictive and construct validity. The combination of the LEMS, BBS, WISCI, 50FW-S, and LFIM appears to encompass adequate descriptors for outcomes of walking trials for incomplete SCI.

The assessment of walking capacity using the walking index for spinal cord injury: self-selected versus maximal levels.

OBJECTIVES: To assess (1) the frequency and magnitude of differences between self-selected and maximal walking capacity following spinal cord injury (SCI) by using the Walking Index for Spinal Cord Injury (WISCI) and (2) how these levels differ in efficiency and velocity. DESIGN: Prospective cohort. SETTING: Academic medical center. PARTICIPANTS: Fifty people with chronic incomplete SCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Subjects ambulated at the level used in the community (self-selected WISCI) and the highest level possible (maximal WISCI). Velocity (in m/s), Physiological Cost Index (PCI), and Total Heart Beat Index (THBI) were calculated. Differences were compared using the paired t test (parametric) or Wilcoxon signed-rank test (nonparametric). RESULTS: For 36 subjects, maximal WISCI was higher than self-selected WISCI; 21 subjects showed an increase of 3 levels or more. Ambulatory velocity was higher for self-selected WISCI compared with maximal WISCI (.68 m/s vs .56 m/s, P<.001). PCI and THBI at self-selected WISCI were lower than at maximal WISCI (PCI, 0.99 beats/m vs 1.48 beats/m, P<.001; THBI, 3.39 beats/m vs 4.75 beats/m, P<.001). CONCLUSIONS: Many people with chronic SCI are capable of ambulating at multiple levels. For these people, ambulation at self-selected WISCI was more efficient as evidenced by greater velocity and decreased PCI and THBI. The findings have implications for assessing walking capacity within the context of clinical trials.

Neurological and functional capacity outcome measures: essential to spinal cord injury clinical trials.

We intend to demonstrate that future treatment strategies in spinal cord injury (SCI) rehabilitation to restore function (SCI rehabilitation) should be based on the success of rigorous clinical trials with demonstrated effective interventions. Knowing the course of neurological recovery, its mechanism, and its measures will be essential in designing and executing these trials. We reviewed selected recovery outcomes and measures from multicenter studies and a large SCI database. The accuracy of baseline examinations in the first days following injury is critical to demonstrating changes in neurological recovery. Recovery of one neurologic level in subjects with tetraplegia depends on the severity of the injury, the initial level of the injury, and the strength of muscles below the level of injury. Motor recovery of the upper limbs typically correlates with self-care function. Neurological recovery following SCI often correlates with an increase in function and walking in addition to self-care. In subjects with paraplegia, predicting recovery of walking is possible based on the initial 1-week sensory and motor examination. Although initial neurological findings correlate with neurological and functional-recovery outcomes in large populations of 3,500 subjects reported by the Model SCI System centers in the United States, improved outcome measures for walking are needed. The Walking Index for Spinal Cord Injury (WISCI) has recently demonstrated criterion validity and increased sensitivity and responsiveness to change in neurological/walking function in subjects with SCI. The WISCI scale correlated well with measures in use to determine improved walking function regarding walking speed, lower-limb motor scores, and other measures. Demonstrating improved neurologic and functional outcomes following SCI requires accurate neurologic and sensitive functional measures.
