Factors Related to Engagement in Employment After Spinal Cord Injury in Australia: A Cross-sectional Study

ObjectiveTo explore the association between sociodemographic, health, functional independence, and environmental variables with engagement in paid work for people with spinal cord injury (SCI).DesignSelf-reported, cross-sectional Australian data from a large international SCI survey.SettingCommunity-based.Participants1189 working-age people with SCI (18-67 years) or aged >67 years and engaged in paid employment. Respondents were community based and at least 1 year after injury.InterventionsNot applicable.Main Outcome MeasuresEmployment and work integration variables. Bayesian penalized regression was used to determine associations between 23 predictor variables and engagement in paid work.ResultsMost participants (87%) were employed pre-injury, with 39% in paid employment at the time of the survey. Participants who attained a master's/doctoral degree (odds ratio [OR]=3.01; 95% credible interval [CrI], 1.63, 5.44) and those married (OR=1.68; 95% CrI, 1.13, 2.49) were more likely to be engaged in paid work. Women (OR=0.55; 95% CrI, 0.37, 0.81), people receiving a disability pension (OR=0.17; 95% CrI, 0.13, 0.24), and older participants (OR=0.75; 95% CrI, 0.63, 0.90) were less likely to be in paid work. Working participants identified hardships including problems completing their work (60%) and accessing the workplace (32%), as well as unmet needs relating to assistive devices required for completing their work (50%).ConclusionsFindings from the current study can assist in directing resources to subgroups within the SCI population who need greater assistance or intervention related to employment outcomes, including through vocational rehabilitation services/programs. Unmet needs and workplace issues expressed by employed individuals identify gaps in work integration and satisfaction that could affect employment sustainability that need to be addressed.     

Motor unit number index examination in dominant and non-dominant hand muscles

This study investigated the effect of handedness on motor unit number index (MUNIX). Maximal hand strength, compound muscle action potential (CMAP) and voluntary surface electromyography (EMG) signals were measured bilaterally for the first dorsal interosseous (FDI) and thenar muscles in 24 right-handed and 2 left-handed healthy subjects. Mean (±standard error) grip and pinch forces in the dominant hand were 43.99 ± 2.36 kg and 9.36 ± 0.52 kg respectively, significantly larger than those in the non-dominant hand (grip: 41.37 ± 2.29 kg, p < .001; pinch: 8.79 ± 0.46 kg, p < .01). Examination of myoelectric parameters did not show a significant difference among the CMAP area, the MUNIX or motor unit size index (MUSIX) between the two sides in the FDI and thenar muscles. In addition, there was a lack of correlation between the strength and myoelectric parameters in regression analysis. However, strong correlations were observed between dominant and non-dominant hand muscles in both strength and myoelectric measures. Our results indicate that the population of motor units or spinal motor neurons as estimated from MUNIX may not be associated with handedness. Such findings help understand and interpret the MUNIX during its application for clinical or laboratory investigations.     

Mindfulness-Based Interdisciplinary Pain Management Program for Complex Polymorbid Pain in Veterans: A Randomized Controlled Trial

ObjectiveTo evaluate the effects of interdisciplinary pain management on pain-related disability and opioid reduction in polymorbid pain patients with 2 or more comorbid psychiatric conditions.DesignTwo-arm randomized controlled trial testing a 3-week intervention with assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up.SettingDepartment of Veterans Affairs medical facility.Participants103 military veterans (N=103) with moderate (or worse) levels of pain-related disability, depression, anxiety, and/or posttraumatic stress disorder randomly assigned to usual care (n=53) and interdisciplinary pain management (n=50). All participants reported recent persistent opioid use. Trial participants had high levels of comorbid medical and mental health conditions.InterventionsExperimental arm—a 3-week, interdisciplinary pain management program guided by a structured manual; comparison arm—usual care in a large Department of Veterans Affairs medical facility.Main Outcome MeasuresOswestry Disability Index (pain disability); Timeline Followback Interview and Medication Event Monitoring System (opioid use). Analysis used generalized linear mixed model with all posttreatment observations (posttreatment, 6-month follow-up, 12-month follow-up) entered simultaneously to create a single posttreatment effect.ResultsVeterans with polymorbid pain randomized to the interdisciplinary pain program reported significantly greater decreases in pain-related disability compared to veterans randomized to treatment as usual (TAU) at posttreatment, 6-month, and 12-month follow-up. Aggregated mean pain disability scores (ie, a summary effect of all posttreatment observations) for the interdisciplinary pain program were -9.1 (95% CI: -14.4, -3.7, P=.001) points lower than TAU. There was no difference between groups in the proportion of participants who resumed opioid use during trial participation (32% in both arms).ConclusionThese findings offer the first evidence of short- and long-term interdisciplinary pain management efficacy in polymorbid pain patients, but more work is needed to examine how to effectively decrease opioid use in this population.     

Sensitivity of MUP parameters in detecting change in early ALS

ObjectivesWe aimed to identify the most appropriate MUP parameter to evaluate reinnervation in very early ALS.MethodsWe studied tibialis anterior (TA), initially of normal strength with normal MUP analysis parameters, in 15 patients with ALS of recent onset. They were studied at the initial diagnostic assessment, and then 3 and 6 months later. Spontaneous EMG activity was recorded. Conventional MUP analysis included mean amplitude, mean area, mean duration, mean number of phases, mean number of turns, % polyphasic potentials, mean jitter, % unstable pairs and % pairs with blocking. Non-parametric statistics were utilised in the analysis.ResultsFasciculations were recorded in 72% in TA and increased jitter in 33% at study entry, but without EMG features of denervation. Mean amplitude, mean duration, mean area and the three measures of neuromuscular transmission increased significantly and linearly at each evaluation. Median duration showed the lowest variation and, together with jitter, the largest relative time effect.ConclusionsMean duration and mean jitter are the most effective measures of early reinnervation in a very early affected muscle, in ALS.SignificanceMean MUP duration is a simple and easy measure that should be useful in evaluating reinnervation, for example in a future clinical trial.     

Relationship of Preinjury Caregiver and Family Functioning to Community Integration in Adults With Traumatic Brain Injury

Sady MD, Sander AM, Clark AN, Sherer M, Nakase-Richardson R, Malec JF. Relationship of preinjury caregiver and family functioning to community integration in adults with traumatic brain injury.

Objective

To investigate the relationship of preinjury caregiver and family functioning to community integration outcomes in persons with traumatic brain injury (TBI).

Design

Inception cohort.

Setting

Three TBI Model Systems inpatient rehabilitation facilities.

Participants

Persons with TBI (N=141) and their caregivers admitted to inpatient rehabilitation and followed up at 1 to 2 years after injury.

Interventions

Not applicable.

Main Outcome Measures

Community Integration Questionnaire and the Social and Occupation scales of the Craig Handicap Assessment and Reporting Technique.

Results

There were significant interactions of several preinjury caregiver and family variables with injury severity. For persons with complicated mild/moderate injury, better family functioning was associated with greater home integration, and less caregiver distress was associated with better social integration. For persons with severe injuries, greater caregiver perceived social support was associated with better outcomes in productivity and social integration.

Conclusions

Preinjury caregiver and family characteristics interact with injury severity to affect outcomes in persons with injury. Research on outcomes should include measures of caregiver and family functioning. Early interventions targeted toward decreasing caregiver distress, increasing support, and improving family functioning may have a positive impact on later outcomes.     

Complex fasciculation potentials and survival in amyotrophic lateral sclerosis

ObjectiveWe investigated the relationship between fasciculation potentials (FPs) and survival in patients with ALS.MethodsIn 85 ALS patients, we prospectively performed needle EMG in five to seven muscles of each patient. The shape of the detected FPs was analyzed by inspection, and FPs with >4 phases were judged as complex FPs. We analyzed the correlation between complex FPs and survival period using the Cox proportional hazard model.ResultsComplex FPs were observed in 47 patients, more frequently in the muscles with normal strength or mild weakness. The presence of complex FPs was associated with shorter survival (hazard ratio 3.055; p = 0.004). The greater the number of muscles with complex FPs, the shorter the survival and the faster the progression speed.ConclusionWide distribution of complex FPs is associated with shorter survival in ALS.SignificanceComplex FPs are useful to predict prognosis of ALS patients and should be evaluated in the EMG examination.     

Optimizing and simplifying post-traumatic amnesia testing after moderate-severe traumatic brain injury despite common confounders in routine practice

The duration of post-traumatic amnesia (PTA) following traumatic brain injury (TBI) is a key diagnostic and outcome indicator. However, concerningly, different PTA paradigms record different PTA durations: some over-estimate, others under-estimate, PTA. Thus, a compromise is implied. The potential effect of in-hospital confounders including opioids is unknown. Three clinical groups were prospectively recruited. Group-1: in-patients with moderate-severe-TBI (MS-TBI), considered likely ‘in-PTA’. Group-2: patients rehabilitating after recent MS-TBI, considered ‘out-of-PTA’. Group-3: orthopaedic in-patients without TBI undergoing elective surgery. Only Groups 1&3 were taking opioids. All were administered the Westmead Post-traumatic Amnesia Scale (WPTAS) and the Galveston Orientation and Amnesia Test (GOAT). Results were obtained in n = 56 (Group-1:n = 18, Group-2:n = 13 and Group-3:n = 25). On WPTAS, Groups 1&3 scored similarly, but significantly lower than, Group-2 (χ² = 8.2, P = 0.017). Contrariwise, on GOAT, Group-1 scored significantly lower than Groups 2&3 (χ² = 23.99, P < 0.001): however, no patient scored GOAT <75. WPTAS showed moderate sensitivity (72%) but poor specificity (40%) in distinguishing Group-1 from Groups 2&3. Contrariwise, GOAT showed 100% specificity but 0% sensitivity. WPTAS ‘day of week’ and ‘pictures’ combined with GOAT ‘transport medium to hospital’, ‘anterograde amnesia’ and ‘retrograde amnesia’ maximized sensitivity (100%), specificity (85–88%), PPV (77–83%) and NPV (100%) in distinguishing Group-1 from Groups 2&3.ConclusionsConfounders including opioids likely affected WPTAS overall, but not GOAT specificity. A merger, whereby WPTAS sensitivity augmented GOAT specificity, was therefore sought. Favourable items from WPTAS (4/12) and GOAT (3/10) together optimized, and yet simplified, PTA testing; despite prevalent clinical confounders. Less, not more, ‘PTA’ items would benefit both patients and staff alike.     

Mental health outcomes among parents of a child who has a developmental disability: Comparing different types of developmental disability

BackgroundThere is very little information on the effects of different types of developmental disability on the mental health of parents of children who have a DD.ObjectiveThis paper compared the mental health of parents of children with Autism Spectrum Disorder (ASD), Down syndrome, Fetal Alcohol Syndrome (FAS) and other types of DD.MethodsA cross-sectional design was used to examine population-level administrative health data for mental health outcomes in cohorts of fathers and mothers of children with four different types of a DD. As well as type of DD, additional variables were examined, these included: sex of the parent, age of the parent at birth of the child with the DD, income, sex of the child with the DD, number of children in the family and place of residence.ResultsFor both fathers and mothers odds of a diagnosis of depression or another mental health problem were associated with type of DD. Parents of children with FAS experienced the greatest odds of a depression or other mental health diagnosis. Odds of a diagnosis for fathers were associated with low income. Odds of a diagnosis for mothers were associated with the sex of the child with the DD.ConclusionsThese findings are important for understanding families which include a child with a DD, as a guide for future research, and for developing effective programs and services for these parents.
