	<p>Point/Counterpoint Case Scenario: A 55-year old man presents to a pain clinic upon referral from his primary care physician. His symptom is axial low back pain. His pain started approximately 1 year earlier without a specific inciting event. He denies radiation of pain into the lower extremities. There is no bowel or bladder involvement. There is no directional preference. He reports pain "all the time," with minimal specific exacerbating or relieving factors. There is no medical-legal involvement. His medical history is significant for hypertension, hypercholesterolemia, obesity, and sleep apnea. He is a divorced father of 2 adult children. He is self-employed local truck driver, and his job also involves some loading and unloading of boxes, although he describes the weight of the boxes as "light." He notes a decreased capacity to coplete job-related activities but states that the pain medication (sustained-release oxycodone, 80 mg twice a day) allows him to work with minimal discomfort. Michael Saulinot, MD, PhD and Adam Schreiber, DO respond with treatment recommendations. Feature editor: Thomas Watanabe, MD.</p>

	<p><strong>Setting:</strong> Inpatient rehabilitation unit at a university hospital</p>
<p><strong>Patient:</strong> 37-year-old male with diabetic myonecrosis.</p>
<p><strong>Case Description:</strong> The patient had a long-standing history of uncontrolled diabetes mellitus with multiple comorbidities, including end-stage renal disease on dialysis and diabetic myonecrosis of the left biceps femoris diagnosed by biopsy and magnetic resonance imaging (MRI.) On this admission, he presented with right leg pain and swelling, found to be a reoccurrence of diabetic myonecrosis in the vastus lateralis, medialis, and intermedius, diagnosed by MRI only. Prior to admission, he lived alone in a wheelchair inaccessible duplex and required minimal assistance with housekeeping.</p>
<p><strong>Assessment/Results</strong>: Upon initial consultation, he ambulated 25-50 feet at a minimum assistance level with a single point cane. As he was unsafe to return home alone, he was transferred to inpatient rehabilitation after a two week acute hospitalization. During his rehabilitation stay, he increasingly was unable to tolerate standing secondary to pain, and at discharge, he was non-ambulatory despite many attempts at pain control and assistive devices for ambulation. His right leg swelling persisted throughout his stay. After five weeks on our unit, he was discharged to a long-term care facility at a wheelchair independent level. One year later he still was not ambulating, and still lived in the long-term care facility.</p>
<p><strong>Discussion:</strong> Diabetic myonecrosis is an uncommon complication of both insulin-dependent and non-insulin dependent diabetics. Symptoms usually resolve on their own with rest and analgesics within weeks to several months. There are reports of physical therapy prolonging the recovery period and exacerbating symptoms, which may have happened with our patient.</p>

	<p><strong>Setting:</strong> University Hospital</p>
<p><strong>Patient:</strong> 65-year-old female status-post liver transplant secondary to cirrhosis.</p>
<p><strong>Case Description</strong>: Prior to the rehabilitation consult on post-operative day 42, she had an episode of acute rejection requiring rapid escalation of cyclosporine dosage, later changed to high dose tacrolimus for immunosuppression, resulting in high blood levels of both calcineurin inhibitors. She then complained of paroxysms of 10/10 pain over her entire body not relieved by opioids despite escalation in medication by the acute pain service. She was not participating in a rehabilitation program because of pain. Examination revealed an anxious woman for whom any tactile stimulation caused profound pain, precluding a thorough neuromuscular examination. She demonstrated spontaneous movement in all four limbs with akathesias.</p>
<p><strong>Assessment/Results:</strong> After a literature search and discussion with the transplant team to determine if calcineurin-inhibitor induced pain syndrome (CIPS) was a likely cause for her pain, the patient’s immunosuppressive regimen was adjusted, as she was no longer in acute rejection. Tacrolimus was stopped, and cyclosporine dosage was gradually increased over several weeks. After her calcineurin inhibitor levels dropped, she had relief of pain such that she no longer required opioids, and could participate fully in an inpatient rehabilitation program. After less than two weeks on our inpatient service, she was discharged at a supervision level for household ambulation with a rolling walker.</p>
<p><strong>Discussion:</strong> CIPS has been described as a cause of disabling pain after organ transplantation. In our patient, treatment of CIPS resulted in improved function. Reducing the blood levels of calcineurin inhibitor is the preferred treatment in the literature, as with our patient. In cases where this is not possible, calcium channel blockers have been used for pain relief.</p>

	<p><strong>Patient:</strong> 31 year old woman chronic flexion contracture of hand, prior history seizure disorder, chronic conversion disorder.</p>
<p><strong>Program Description:</strong> Patient presented initially to neurology service with chronic right hand flexion contracture in the context of 3 days of weakness and numbness in lower extremities after exertion.  MRI/MRA Brain, Head CT, CT of entire spine were all unrevealing.  Patient was transferred to the rehabilitation unit 8 days after initial admission.  On rehabilitation admission patient exam was noted to have right hand markedly flexed with pain to passive ranging out of extreme flexion, chronic in nature.  Patient initially had her hand ranged in the context of traditional therapy with limited success; however with use of EMG biofeedback patient was able to move all five metacarpophalangel joints on rehabilitation day 4, patient remarking that she was right handed again.  Her pain level also dramatically decreased.  Her overall functional status improved markedly by discharge and though she remained with decreased active range-of-motion in her right-hand, it did not detract from her overall functional status.</p>

	<![CDATA[
	<p><strong>Setting</strong>: University hospital-based acute rehabilitation.</p>
<p><strong>Patient:</strong> 75-year-old woman with Stiff-Person Syndrome (SPS) with a recent fall and Colles fracture.</p>
<p><strong>Case Description:</strong> Four months prior to admission, the patient was diagnosed with SPS, negative for anti-GAD antibodies. Diagnosis was based on a 3-year history of progressive rigidity leading to frequent falls and fractures. Anxiety and fear of falling limited her mobility, and she sustained a sacral pressure ulcer during acute hospitalization. On admission, history was remarkable for unsteady gait and muscle cramps exacerbated when startled or excited. Examination was remarkable for rigidity in her axial and limb muscles. She presented at the maximal assist level for transfers and toileting and moderate assist level for grooming and ambulation using a platform walker (right arm in cast). She was unable to tolerate titration of diazepam due to sedation, or baclofen due to hypotension.</p>
<p><strong> Results:</strong> During acute rehabilitation, rigidity was treated with titration of dantrolene (from 25 to 50 mg four times daily) in addition to maximal tolerated doses of diazepam (1 mg qAM/2 mg qPM) and baclofen (20mg TID). The addition of dantrolene reduced rigidity and improved range of motion, both subjectively per patient and objectively by exam. Functional gains stalled with dose decrease and resumed with dose increase. She had pronounced gains in grooming to the supervision level, modest gains in transfers and toileting to the moderate assist level, but remained at the moderate assist level for ambulation. Progress was limited due to a change to non-weight bearing status of her right arm. Anxiety and depression were improved with buspirone, paroxetine, and psychological counseling.</p>
<p><strong>Discussion:</strong> SPS results in significant activity of daily life and ambulatory dysfunction as exemplified by her pressure ulcer and multiple falls. Although GABA agonists are the preferred treatment for SPS, the adverse effects of high doses can increase the risk of falls. Dantrolene reduced muscle rigidity and improved function without sedative or hypotensive effects.</p>
<p><strong>Conclusion:</strong> Dantrolene is a useful additional treatment for SPS rigidity.</p>

	<p>With the International Classification of Functioning, Disability and Health (ICF) the World Health Organization (WHO) has prepared the ground for a comprehensive understanding of Human Functioning and Rehabilitation Research, integrating the biomedical perspective on impairment with the social model of disability. This poses a number of old and new challenges regarding the enhancement of adequate research capacity. Here we will summarize approaches to address these challenges with respect to 3 areas: the organization of Human Functioning and Rehabilitation Research into distinct scientific fields, the development of suitable academic training programmes and the building of university centres and collaboration networks.</p>

	<![CDATA[
	<p>The goal of delivering quality health care at a lower overall cost through accountable care organizations (ACO) as described as part of the Patient Protection and Affordable Care Act of 2010 (ACA) has gained momentum among payers, providers, and the public. The concept includes developing an organization that provides incentives for quality care while lowering the overall cost of the care. If the goals are met, then both providers and payers would be able to share in the financial savings produced by the lower health care costs achieved while improving the quality of care delivered. The Centers for Medicare and Medicaid Services (CMS) has further defined ACOs in the proposal rule released March 31, 2011, in the Medicare Shared Savings Program: Accountable Care Organizations. Medicare has projected that, over the first 3 years, there will be 75-150 ACOs developed, resulting in coverage of 1.5-4.0 million Medicare beneficiaries. This initial phase has been projected to save Medicare $510-$800 million in health care costs [1,2]. Regardless of whether or not this initial model of ACOs will have long-term validity, it is likely that components of the model will be included in future health care reform; therefore, physical medicine and rehabilitation (PM&R) providers will have to decide how they will respond to these future changes. This article describes some of the CMS proposed ACO regulations and strategies that practices might consider to prepare for the future.</p>

	<![CDATA[
	<p>Selecting appropriate outcome measures in spinal cord injury clinical trials that aim to improve spinal cord function is a challenging task. Proving that an intervention has the intended effect on neurological functioning is insufficient. Any improvement must be shown to be clinically significant-that is, makes a change in the life of the person. Rehabilitation, which seeks to maximize function despite residual impairments, complicates this task. Small improvements in function due to a spinal cord intervention may be masked by improvements in function due to rehabilitation, particularly in the initial rehabilitation phase of care. Understanding outcome domains in models of disablement will facilitate selection or development of assessment tools appropriate for the trial in question. This article describes an expanded World Health Organization model of functioning that defines the domains of Impairment, Capability/Functional Limitation, and Activity, as well as the subdomains of Capacity and Performance, and gives examples of measurement instruments in use or under development in each domain.</p>

	<![CDATA[
	<p>Presented in part at the AAPMR 71st Annual Assembly Meeting, Seattle, WA, November 4-7, 2010.</p>
<p>Atlantoaxial instability results from cartilaginous destruction, periarticular erosions, and ligament and tendon attenuation. Instability affects 19%-70% of patients, and basilar invagination from vertical odontoid subluxation through the foramen magnum occurs in 38% of patients. This phenomenon occurs twice as often in women than men, whose age at diagnosis typically ranges from 30-50 years. Along with bony compression, the pannus further decreases the space available for the cord by 3mmor more in approximately 66% of patients (Figures 1-7). The earliest and most common symptom of cervical subluxation is pain radiating up into the occiput with associated headaches. Episodes of medullary dysfunction that represent severe but less common patterns of progressive myelopathic symptoms provide an even more grim prognosis. When cervical myelopathy is established, 50% of these patients die within 1 year.</p>

	<p>HIV-associated Guillain-Barré Syndrome is a well-documented phenomenon, typically occurring at seroconversion. GBS may result in functional impairment treated with a combination of medications, plasmapheresis, and rehabilitation.  The quantified functional recovery of HIV-associated GBS with or without HIV treatment is not well-described.  Utilizing serial FIM scoring, we describe a patient’s recovery from HIV-associated GBS after treatment with IVIg and acute inpatient rehabilitation without HIV treatment.</p>

<description>
	<![CDATA[
	<p><strong>Conclusion:</strong></p>
<p>Our data is consistent with prior studies in demonstrating that the incidence of dural puncture and CSF leak with SCS procedures is rare.  Based on our experiences, performing an epidural blood patch intra-operatively on the contra-lateral side under fluoroscopy could prevent PDPH.  This treatment should especially be considered in patients undergoing SCS trials in order to accurately assess the level of pain reduction.  Patients with prior spine surgeries might pose higher risks for dural puncture and more extensive pre-operative assessment could be beneficial.</p>

	<p>The TFR is a sign of upper motor neuron impairment.  It does not typically appear for several days after an injury but in patients with pre-existing myelopathy, an early onset exaggerated Babinski response exhibited as a TFR may occur.  It is important not to misinterpret such responses as volitional movements, particularly in patients with cognitive dysfunction where the history and physical examination may be limited.  Failure to immobilize the spine and to administer adjunct steroid therapy may be detrimental to the patient.  Education of initial response physicians may prevent overlooking an acute SCI.</p>

<description>
	<![CDATA[
	<p>Cysts that are clearly associated with threat of progressive neurological loss or intractable, unremitting symptoms should be released by a decompression procedure.</p>
<p>In our case series, percutaneous aspiration has been successfully used for 3 of 4 PTs with marked decrease in size of cyst on imaging and clinical improvement.</p>
<p>Obstructing pathology and ultimately the location of the cyst can be major factors in determining the success of the procedure.</p>
<p>Our study demonstrated that a minimally invasive aspiration of a ZP SC can often achieve clinical improvement.</p>
<p>This may save the PT from undergoing an invasive surgical decompression.</p>

<description>
	<![CDATA[
	<p>We describe the inpatient clinical rehabilitation course of three patients with neuromyelitis optica (NMO; Devic’s Syndrome). These patients had varying functional deficits.  Each patient improved in several functional independence measures (FIM domains), but had minimal to no progress in other domains after acute rehabilitation stays between 1 to 1.5 months.  NMO is a severe central nervous system demyelinating syndrome distinct from MS, characterized by optic neuritis, myelitis, and at least two of three criteria: longitudinally extensive cord lesion, MRI nondiagnostic for multiple sclerosis, or NMO-IgG seropositivity.  Persons with NMO may demonstrate improved function with rehabilitation efforts; though gains may be lost to relapse    Future immunomodulatory intervention may augment the benefits of rehabilitation.</p>

<title>Continuous ASL perfusion fMRI investigation of higher cognition:  Quantification of tonic CBF changes during sustained attention and working memory tasks</title>

<description>
	<![CDATA[
	<p>Arterial spin labeling (ASL) perfusion fMRI is an emerging method in clinical neuroimaging. Its non-invasiveness, absence of low frequency noise, and ability to quantify the absolute level of cerebral blood flow (CBF) make the method ideal for longitudinal designs or low frequency paradigms. Despite the usefulness in the study of cognitive dysfunctions in clinical populations, perfusion activation studies to date have been conducted for simple sensorimotor paradigms or with single-slice acquisition, mainly due to technical challenges. Using our recently developed amplitude-modulated continuous ASL (CASL) perfusion fMRI protocol, we assessed the feasibility of a higher level cognitive activation study in twelve healthy subjects. Taking advantage of the ASL noise properties, we were able to study tonic CBF changes during uninterrupted 6-min continuous performance of working memory and sustained attention tasks. For the visual sustained attention task, regional CBF increases (6–12 ml/100 g/min) were detected in the right middle frontal gyrus, the bilateral occipital gyri, and the anterior cingulate/medial frontal gyri. During the 2-back working memory task, significantly increased activations (7–11 ml/100 g/min) were found in the left inferior frontal/precentral gyri, the left inferior parietal lobule, the anterior cingulate/medial frontal gyri, and the left occipital gyrus. Locations of activated and deactivated areas largely concur with previous PET and BOLD fMRI studies utilizing similar paradigms. These results demonstrate that CASL perfusion fMRI can be successfully utilized for the investigation of the tonic CBF changes associated with high level cognitive operations. Increased applications of the method to the investigation of cognitively impaired populations are expected to follow.</p>

<title>Measuring sustained attention after traumatic brain injury:  Differences in key findings from the sustained attention to response task (SART)</title>

<description>
	<![CDATA[
	<p>Clinical reports after traumatic brain injury (TBI) suggest frequent difficulties with sustained attention, but their objective measurement has proved difficult. In 1997, Robertson and colleagues reported on a new sustained attention assessment tool, the sustained attention to response task (SART). Individuals with TBI were reported to produce more errors of commission on the SART than control participants, and both groups showed a relationship between SART errors and everyday lapses of attention as measured by the cognitive failures questionnaire (CFQ). Although few direct replications of these findings have been reported, the SART has been used widely as a measure of sustained attention in TBI, in normal controls, and in various other clinical samples.</p>
<p>As part of a program of research on attention in TBI, we administered the SART and the CFQ to a sample of 34 survivors of moderate to severe TBI and to 35 control participants. CFQ scores reported by significant others showed clear group differences in everyday lapses of attention. Despite this, group differences in SART errors of commission were small and non-significant, and the correlations between SART errors and CFQ scores were small within both groups. Further analyses excluding participants with invalid score profiles, or restricting the analysis to the first performance of the SART failed to alter the results.</p>
<p>These findings suggest that more research is needed to establish the validity of the SART as a measure of sustained attention after TBI, and to determine under what circumstances the original findings hold.</p>
