Abstract: BACKGROUND: Children with cerebral palsy (CP) perform less physical activity than their typically developing peers (TDP). Pain, important comorbidity in children with CP, restrains levels of physical activity. OBJECTIVE: This study aims at exploring the influence of chronic pain in physical activity of children with CP and TDP. METHODS: 24-hour heart rate was registered in four groups of children: children with CP and TDP, with and without chronic pain. Heart rate based indexes of physical activity (MET percentages, energy expenditure) were computed. A self-reported diary of activities rated activities pain and fatigue intensity. RESULTS: …Children with CP and chronic pain reported more painful activities and higher pain than their TDP with chronic pain. Moreover, children with CP and chronic pain presented higher time and periods of light activity and less sedentary activity than their TDP with chronic pain. No differences were found between CP and TDP without chronic pain. CONCLUSION: Children with CP regulate physical activity differently than TD children in the presence of chronic pain. The maintenance of light levels of physical activity in children with CP may suggest efficient pain coping strategies and perseverance in participation. These findings encourage the implementation of programs to improve fitness in this population. Show more

Abstract: OBJECTIVES: This study investigated the feasibility of modulating bilateral corticospinal excitability with different polarities of transcutaneous spinal direct current stimulation (tsDCS) in chronic, incomplete spinal cord injury (SCI). METHODS: Six subjects with chronic incomplete SCI (>12 months post injury) participated in this crossover study. Intervention consisted of 3 sessions, separated by at least 1 week, in which each subject received the conditions cathodal, anodal, and sham tsDCS. Stimulation was delivered at 2.5 mA for 20 minutes with the active electrode positioned over the spinous processes of T10-T11 and the reference electrode over left deltoid. To measure the effects …of tsDCS on corticospinal excitability, motor evoked potentials (MEPs) from transcranial magnetic stimulation were measured bilaterally from soleus before and after tsDCS. RESULTS: Five subjects completed all 3 sessions. One subject withdrew after 2 sessions due to complications unrelated to the study. MEPs were measurable in 5 subjects. No significant differences in change of MEP amplitudes were found between the 3 conditions. However, there were trends that indicated laterality of response, particularly with cathodal tsDCS increasing corticospinal excitability contralateral to the reference electrode and decreasing corticospinal excitability ipsilateral to the reference electrode. CONCLUSION: Corticospinal excitability may be modulated with laterality by tsDCS in individuals with chronic, incomplete SCI. Further research is needed to 1) determine whether different placement of the reference electrode can lead to uniform modulation bilaterally, and 2) reveal whether these alterations in corticospinal excitability can lead to improved movement function in individuals with chronic, incomplete SCI.

Abstract: BACKGROUND: Tibialis Anterior (TA) cutaneous reflex (CR) activity evoked following cutaneous stimulation of the plantar (Pl) surface (Pl-TA CR) has demonstrated hyperreflexia and damage of inhibitory mechanisms in subjects with spinal cord injury (SCI) and spasticity. OBJECTIVES: To modulate Pl-TA CR and Soleus H-reflex activity with transcutaneous electrical nerve stimulation (TENS) and vibratory stimulation of the plantar pad during rest and controlled isometric plantarflexion. METHODS: Non-injured subjects (n = 11) and individuals with incomplete SCI with (n = 14) and without spasticity (n = 14) were recruited. The effect of TENS and vibratory …stimuli on Pl-TA CR and soleus H-reflex activity were assessed during rest and controlled ramp-and-hold plantarflexion. RESULTS: Vibration failed to inhibit H-reflex activity during rest or plantarflexoin following SCI compared to healthy subjects. In contrast, vibration-induced inhibition of Pl-TA CR was specifically detected in SCI spastic subjects during both rest and the hold phase of plantarflexion. TENS inhibited Pl-TA CR activity in the SCI spasticity group only during hold plantarflexion. CONCLUSIONS: Plantar vibratory stimuli inhibited the pl-TA CR, but not the H reflex, during rest and controlled movement in SCI spastic subjects. Assessment of Pl-TA CR modulation should contribute to the development of modality-specific sensory stimuli programmes for the neurorehabilitation of SCI spasticity. Show more

Abstract: BACKGROUND: The emergence of mobile technology allows the examination of balance through direct measures of postural sway in a cost-effective, convenient and portable fashion. However, there is insufficient evidence for use in populations with neurologic conditions. OBJECTIVES: 1) To determine the test-retest reliability of the Sway Balance™ mobile application in measuring postural sway in individuals with Parkinson disease, 2) To examine the concurrent validity of Sway Balance™ with inertial measurement units and 3) To determine if Sway Balance™ scores can predict disease severity. METHODS: Thirty subjects with early stage idiopathic Parkinson disease completed three trials of …two Sway Balance™ protocols while postural sway was simultaneously measured by two inertial measurement units and Sway Balance™, then repeated testing one week later. RESULTS: Sway Balance demonstrated high test-retest reliability for both protocols (ICC = 0.72 and 0.92) and good to excellent inverse correlation with the inertial measurement units across both protocols (ρ = –0.61– –0.92; p < 0.001). Sway Balance™ did not accurately predict disease severity. CONCLUSION: Sway Balance™ demonstrates strong test-retest reliability and concurrent validity with measures from inertial measurement units. Questions remain regarding the ability of Sway Balance™ to accurately characterize balance of individuals who demonstrate difficulty maintaining the test condition. Show more

Abstract: BACKGROUND: About 5–15 % of patients with concussion experience persistent post-concussion symptoms (PCS) longer than 3 months post-injury. OBJECTIVE: To explore the feasibility of a new intervention for young patients with persistent PCS and long-term changes after intervention. METHODS: Thirty-two consecutive patients (15–30 years) with persistent PCS 2–4 months post-injury were recruited from a cohort study or referred to a non-randomized feasibility study of an individually tailored, 8-week, multidisciplinary intervention. Assessment was performed at baseline, end of intervention (EOI), and at 3- and 12-month follow-up (FU). Main measures were The Experience of Service Questionnaire (ESQ), Rivermead …Post-Concussion Symptoms Questionnaire (RPQ) and The Quality of Life after Brain Injury - Overall Scale (QOLIBRI-OS). RESULTS: Twenty-three (72%) patients completed the intervention. The ESQ demonstrated high patient satisfaction. There was a decrease of PCS and an increase in quality of life from baseline to EOI: RPQ score –8.9 points, 95% CI 4.5 to 13.3, p < 0.001; QOLIBRI-OS score +10.5 points, 95% CI 2.5 to 18.5, p = 0.010. Improvement was maintained at 3- and 12-month FU. CONCLUSION: The new early intervention is feasible and may prevent chronification of PCS. An RCT is currently performed to evaluate the effect of the intervention. Show more

Abstract: BACKGROUND: Preinjury employment status may contribute to disparity, injury risk, and recovery patterns following mild traumatic brain injury (MTBI). OBJECTIVE: To characterize associations between preinjury unemployment, prior comorbidities, and outcomes following MTBI. METHODS: MTBI patients from TRACK-TBI Pilot with complete six-month outcomes were extracted. Preinjury unemployment, comorbidities, injury factors, and intracranial pathology were considered. Multivariable regression was performed for employment and outcomes, correcting for demographic and injury factors. Mean-differences (B ) and 95% CIs are reported. Statistical significance was assessed at p < 0.05. RESULTS: 162 MTBI patients were aged 39.8±15.4-years and 24.6% …-unemployed. Unemployed patients demonstrated increased psychiatric comorbidities (45.0% -vs.– 23.8%; p = 0.010), drug use (52.5% -vs.– 21.3%; p < 0.001), smoking (62.5% -vs.– 27.0%; p < 0.001), prior TBI (78.4% -vs.– 55.0%; p = 0.012), and lower education (15.0% -vs.– 45.1% college degree; p = 0.003). On multivariable analysis, unemployment associated with decreased six-month functional outcome (Glasgow Outcome Scale-Extended: B = – 0.50, 95% CI [– 0.88, – 0.11]), increased psychiatric disturbance (Brief Symptom Inventory-18: B = 6.22 [2.33, 10.10]), postconcussional symptoms (Rivermead Questionnaire: B = 4.91 [0.38, 9.44]), and post-traumatic stress disorder (PTSD Checklist-Civilian: B = 5.99 [0.76, 11.22]). No differences were observed for cognitive measures or satisfaction with life. CONCLUSIONS: Unemployed patients are at risk for preinjury psychosocial comorbidities, poorer six-month functional recovery and increased psychiatric/postconcussional/PTSD symptoms. Resource allocation and return precautions should be implemented to mitigate and/or prevent the decline of at-risk patients. Show more

Abstract: BACKGROUND: Flow is an optimal psychological state when people engage in a training task, and it is a theory explaining the absorbed state. OBJECTIVE: To investigate the additional effect of flow on attention deficits for chronic patients after traumatic brain injury. METHODS: Twenty patients were randomly assigned to the flow group (n = 10) or the control group. Patients performed a video game task, one inducing flow (flow group) and the other not (control group) for 4 weeks, and they were assessed with the flow state scale for occupational tasks (FSSOT) regularly and neuropsychological tests …at baseline, after intervention, and at 4 weeks after intervention (follow-up). RESULTS: Although both groups significantly improved their attentional function after intervention, patients in the flow group tended to show more improvement of attention. The effect size of the neuropsychological test of attention was positive, and its value was small to medium. There was a significant positive correlation between improvement of attention and the FSSOT score. CONCLUSIONS: Attention training with induction of the flow was associated with greater improvement of attention. The results of this study may provide provisional evidence of the effectiveness of rehabilitation considering the patient’s psychological state. Show more

Abstract: OBJECT: Recent efforts in neurocritical care have emphasized optimal timing and employment of rehabilitation services. However, there is sparse literature on the effect of team approaches to the intensive care patient. The aim of this study was to evaluate the effect of increased coordination between a physical therapist and an attending cerebrovascular neurosurgeon through daily multidisciplinary rounds. METHODS: A retrospective review was performed of 235 patients who were admitted to the neuroscience service under a single cerebrovascular neurosurgeon over a 16-month period (April 2014 through July 2015) in a level-I trauma hospital. The study consisted of an eight-month …pre-intervention period (n = 117) where the physical therapist did not attend physician rounds and an eight-month post-intervention period (n = 118). RESULTS: In the post-intervention group the physical therapy (PT) assessment occurred on average 1.57 days sooner (p < 0.001). Hospital Length of Stay (LOS) decreased by an average of 3.46 days (p = 0.04) and ICU LOS decreased on average by 1.83 days (p = 0.05) in the post-intervention group. Ventilator days decreased on average by 0.55 days, which was not statistically significant (p = 0.26). CONCLUSIONS: In conclusion, daily coordination with multidisciplinary rounds between the physician and the physical therapist was associated with decreased time to initial PT assessment, decreased hospital LOS, and decreased ICU LOS in the neuroscience population.

Abstract: BACKGROUND: Homonymous hemianopia post-stroke reduces independence. OBJECTIVE: To compare the effectiveness of a standardised program versus current individualized therapy in patients with homonymous hemianopia. METHODS: Single-blind randomized controlled trial, 24 patients (54% male), mean age (65±4.3), mean time since stroke (51±52.3 days), recruited from rehabilitation and vision services in Adelaide, Australia. Participants were randomized to a combined standardized scanning and mobility program of 7 weeks, 3 times per week or to individualized therapy recommended by clinicians. Primary outcome was an assessment of scanning ability whilst walking. Secondary outcomes included measures of visual scanning, reading, and vision …related quality of life (QOL). RESULTS: No significant differences were found between intervention groups for the primary outcome measure of scanning ability whilst walking at 7 weeks and at 3 months (P > 0.05). However, at 3 months significant differences were found for the QOL National Eye Institute Visual functioning Questionnaire (NEI VFQ25) total score (P = 0.03) and dependency sub-score (P = 0.03) measures. CONCLUSIONS: A standardized intervention of static scanning and mobility training improved QOL. Allocation of resources to visual rehabilitation services point towards the implementation of more mobility practice over a longer period of time. Show more
