BACKGROUND: Contemporary goals of rehabilitation after traumatic brain injury (TBI) aim to improve cognitive and motor function by applying concepts of neuroplasticity. This can be challenging to carry out in TBI patients with motor, balance, and cognitive impairments. OBJECTIVE: To determine whether use of dynamic body-weight support (DBWS) would allow safe administration of intensive motor therapy during inpatient rehabilitation and whether its use would yield greater improvement in functional recovery than standard-of-care (SOC) therapy in adults with TBI. METHODS: Data in this retrospective cohort study was collected from patients with TBI who receive inpatient rehabilitation incorporating DBWS (n = 6) and who received inpatient rehabilitation without DBWS (SOC, n = 6). The primary outcome measure was the change in Functional Independence Measures (FIM) scores from admission to discharge. RESULTS: There was significant improvement in total FIM scores at discharge compared to admission for both the DBWS (p = 0.001) and SOC (p = 0.005) groups. Overall, the DBWS group had greater improvement in total FIM score and FIM subscales compared to the SOC group. CONCLUSIONS: Our results suggest DBWS has the potential to allow a greater intensity of therapy during inpatient rehabilitation and yield better outcomes compared to SOC in patients with TBI.

BACKGROUND: Stroke continues to be a major public health concern in the United States. Motor recovery in the post-acute stages of stroke is possible due to neuroplasticity, or the capacity of the brain to reorganize. OBJECTIVE: This case study tracks neuroplastic and motor change in a subject with severe hemiparesis following an extensive middle cerebral artery stroke. He had absence of ipsilesional motor evoked potentials in early evaluations. This report is unique in that the duration of follow-up evaluation extends nearly 2 years, with evaluations being performed at 7, 9, 10, 13, 20, and 21 months post-stroke. METHODS: At each evaluation we used transcranial magnetic stimulation to track neuroplastic change and the Fugl-Meyer Assessment and the Wolf Motor Function Test to evaluate upper extremity motor performance. RESULTS: The contralesional hemisphere showed dynamic change throughout the study period. In contrast, the ipsilesional hemisphere demonstrated notable change only between 13 and 21 months post-stroke, with the most dramatic change occurring between 20 and 21 months post-stroke. Motor performance generally improved throughout the study period. CONCLUSIONS: Our findings demonstrate that substantial neuroplasticity-mediated motor recovery can occur nearly 2 years after stroke in an individual with severe post-stroke motor impairment.

OBJECTIVE. We evaluated the effects of occupation-based intervention on poststroke upper-extremity (UE) motor recovery, neuroplastic change, and occupational performance in 1 research participant. METHOD. A 55-yr-old man with chronic stroke and moderately impaired UE motor function participated in 15 sessions of occupation-based intervention in a hospital setting designed to simulate a home environment. We tested behavioral motor function (Fugl-Meyer Assessment, Stroke Impact Scale, Canadian Occupational Performance Measure) and neuroplasticity (transcranial magnetic stimulation [TMS]) at baseline and at completion of intervention. We collected descriptive data on occupational participation throughout the study. RESULTS. All behavioral outcomes indicated clinically relevant improvement. TMS revealed bihemispheric corticomotor reorganization. Descriptive data revealed enhanced occupational performance. CONCLUSION. Occupation-based intervention delivered in a hospital-based, homelike environment can lead to poststroke neuroplastic change, increased functional use of the affected UE, and improved occupational performance.

Abstract: Foster DJ, Good DC, Fowlkes A, Sawaki L. Atomoxetine enhances a short-term model of plasticity in humans. Objective: To evaluate the role of 2 noradrenergic drugs in modulating use-dependent plasticity in humans. Design: Double-blind, randomized, and placebo-controlled crossover design. Setting: A laboratory in a hospital. Participants: A convenience sample of 10 healthy subjects. Intervention: An established paradigm that measures motor memory as a short-term model of use-dependent plasticity. Subjects attended 3 sessions, separated by at least 1 week to allow drug washout. Subjects received atomoxetine (Strattera), venlafaxine (Effexor), or placebo. Main Outcome Measure: Increase in the proportion of movements into the training target zone (TTZ), an indicator of enhanced plasticity. Results: Atomoxetine, but not venlafaxine, significantly increased movements into the TTZ. Conclusions: These results support a role for norepinephrine in enhancing cortical plasticity and suggest potential benefits in using these drugs for improving motor recovery after stroke.

Background: Dynamic body-weight support (DBWS) may play an important role in rehabilitation outcomes, but the potential benefit among disease-specific populations is unclear. In this study, we hypothesize that overground therapy with DBWS during inpatient rehabilitation yields greater functional improvement than standard-of-care in adults with non-traumatic spinal cord injury (NT-SCI).Methods: This retrospective cohort study included individuals diagnosed with NT-SCI and undergoing inpatient rehabilitation. All participants were recruited at a freestanding inpatient rehabilitation hospital. Individuals who trained with DBWS for at least three sessions were allocated to the experimental group. Participants in the historical control group received standard-of-care (i.e., no DBWS). The primary outcome was change in the Functional Independence Measure scores (FIMgain).Results: During an inpatient rehabilitation course, participants in the experimental group (n = 11), achieved a mean (SD) FIMgain of 48 (11) points. For the historical control group (n = 11), participants achieved a mean (SD) FIMgain of 36 (12) points. From admission to discharge, both groups demonstrated a statistically significant FIMgain. Between groups analysis revealed no significant difference in FIMgain (p = 0.022; 95% CI 2.0-22) after a post hoc correction for multiple comparisons. In a secondary subscore analysis, the experimental group achieved significantly higher gains in sphincter control (p = 0.011: 95% CI 0.83-5.72) with a large effect size (Cohen's d 1.19). Locomotion subscores were not significantly different (p = 0.026; 95% CI 0.37-5.3) nor were the remaining subscores in self-care, mobility, cognition, and social cognition.Conclusions: This is the first study to explore the impact of overground therapy with DBWS on inpatient rehabilitation outcomes for persons with NT-SCI. Overground therapy with DBWS appears to significantly improve functional gains in sphincter control compared to the standard-of-care. Gains achieved in locomotion, mobility, cognition, and social cognition did not meet significance. Findings from the present study will benefit from future large prospective and randomized studies.

Although the physiatric community increasingly embraces evidence-based medicine (EBM), the current state of EBM training for trainees in physiatry is unclear. The purposes of this article are to report the results of the Association of Academic Physiatrists' surveys of physiatry residency programs in the United States, to discuss the implications of their findings, and to better delineate the "baseline" upon which sound and clear recommendations for systematic EBM training can be made. The two Association of Academic Physiatrists surveys of US physiatry residency programs reveal that most survey respondents report that they include EBM training in their programs that covers the five recommended steps of EBM core competencies. However, although most respondents reported using traditional pedagogic methods of training such as journal club, very few reported that their EBM training used a structured and systematic approach. Future work is needed to support and facilitate physiatry residency programs interested in adopting structured EBM training curricula that include recommended EBM core competencies and the evaluation of their impact.

Rehabilitation strategies after traumatic spinal cord injury aim to maximize functional recovery by applying principles of neuroplasticity via task-specific, repetitive training. Rehabilitation of patients with traumatic spinal cord injury poses unique challenges, including bilateral limb involvement, autonomic dysfunction, loss of proprioception, and potentially spinal precautions/bracing. The purpose of this retrospective case series was to determine whether use of dynamic body weight support would yield greater improvement in functional recovery compared with standard of care in adults with traumatic spinal cord injury. Data were collected from patients with traumatic spinal cord injury who completed inpatient rehabilitation incorporating dynamic body weight support (n = 5) and who completed inpatient rehabilitation without dynamic body weight support (n = 5). The primary outcome measure was the change in Functional Independence Measures. The dynamic body weight support group had a significantly greater improvement in Total Functional Independence Measures and in Functional Independence Measures motor subscale compared with the standard of care group (P = 0.023 and P = 0.033, respectively). This study presents initial evidence that dynamic body weight support therapy during inpatient rehabilitation has the potential to improve functional independence compared with standard of care in patients with traumatic spinal cord injury. Larger prospective randomized studies need to be conducted to expand on these findings. [ABSTRACT FROM AUTHOR]
