Investigating Characteristics of Quality Peer Mentors With Spinal Cord Injury

ObjectiveTo identify characteristics (1) of high- and low-quality spinal cord injury (SCI) peer mentors; (2) that should be used to match SCI peer mentors and mentees.DesignThe study was conducted in partnership with three Canadian provincial SCI organizations using an integrated knowledge translation approach. The Delphi exercise was completed in three rounds. In Round 1, people with SCI completed a thought-listing exercise to identify characteristics of high- and low-quality peer mentors and for matching. In Rounds 2 and 3, people with SCI and community organization staff rated characteristics from the previous round on an 11-point scale. After the final round, the remaining characteristics were thematically analyzed.SettingCommunity-based peer mentorship programs in three Canadian provinces.ParticipantsPeople with SCI and SCI community organization staff (Round 1, n=45; Round 2, n=27; Round 3, n=25).InterventionsNot applicable.Main Outcome MeasuresConsensus-based list of characteristics.ResultsParticipants reached consensus on 215 characteristics of quality peer mentors and 11 characteristics for peer mentor-mentee matching (ICC=0.96). A consensus-based characterization of high- and low-quality peer mentorship was created and included six overarching themes: competencies, personality characteristics, emotional state, mentor outlook, reason for mentoring, and role model.ConclusionA consensus-based characterization of quality peer mentorship was co-developed with input from over 50 members of the SCI community. Findings highlight that peers have both interpersonal and intrapersonal characteristics that contribute to quality mentorship. The findings highlighted the importance of matching mentors on lived experience and shared interests. Findings will inform future research and SCI peer mentorship programs.     

Motor pattern of periodic limb movements in sleep in idiopathic RLS patients

Objective: Periodic limb movements in sleep (PLMS) are recurrent sleep-related movements that often occur in association with restless legs syndrome (RLS). The purpose of the present study was to examine the pathophysiology of PLMS in patients with idiopathic RLS.Methods: Ten patients with idiopathic RLS who were medication-free or who had withdrawn from medication at least 2 weeks prior to the study underwent an extensive neurophysiological investigation that included nocturnal video-polysomnographic recording (VPSG), EMG recording, and the Multiple Sleep Latency Test (MSLT). Sleep efficiency and PLMS index were calculated during VPSG.Results: All patients had an increased PLMS index, decreased sleep efficiency, and a pathological MSLT score. Leg muscles were the first to be activated, often with alternation of side, and no constant recruitment pattern could be found from one episode of PLMS to another, even in the same patient. No ordinate caudal or rostral spread of the EMG activity was observed.Conclusions: The results suggest that there are different, independent, and unsynchronized generators for PLMS. The direct participation of the cerebral cortex in the origin of PLMS is unlikely, suggesting that abnormal spinal cord hyperexcitability may act as the primary cause of PLMS, triggered by unidentified sleep-related factors.     

Preinjury predictors of life satisfaction at 1 year after traumatic brain injury

Davis LC, Sherer M, Sander AM, Bogner JA, Corrigan JD, Dijkers MP, Hanks RA, Bergquist TF, Seel RT. Preinjury predictors of life satisfaction at 1 year after traumatic brain injury.ObjectiveTo investigate the predictive value of preinjury factors for satisfaction with life (SWL) at 1-year posttraumatic brain injury (TBI).DesignSecondary analysis of prospective, longitudinal registry using data collected during inpatient rehabilitation and at 1-year post-TBI.SettingFifteen specialized brain injury units providing acute rehabilitation care as part of the Traumatic Brain Injury Model Systems (TBIMS) program.ParticipantsCommunity-dwelling persons (N=444) with moderate to severe TBI aged 16 to 64 years enrolled in the TBIMS program between October 2007 and October 2008 with 1-year follow-up data.InterventionsNot applicable.Main Outcome MeasureSatisfaction With Life Scale (SWLS).ResultsHierarchical stepwise linear regression revealed that injury-related and demographic variables did not contribute significantly to the explained variance in SWLS scores. In contrast, the preinjury functioning (education, productivity/employment) and preinjury condition (psychiatric and substance use problems, severe sensory dysfunction, learning problems, prior TBI) blocks each contributed significantly to the explained variance in SWLS scores. Preinjury functioning accounted for 2.9% of the variance and preinjury conditions for 3.8%.ConclusionsAlthough their contributions are small, preinjury functioning and preinjury conditions are important to consider in the prediction of SWL post-TBI. Educational level and history of psychiatric and other premorbid difficulties are particularly important for clinicians to consider when implementing or developing interventions for persons with moderate to severe TBI.     

Depression in Older Adults 12 Months After Traumatic Brain Injury: A TRACK-TBI Study

ObjectiveTo investigate depression at 12 months after traumatic brain injury (TBI) in older adults compared with younger adults.DesignProspective longitudinal cohort study of persons with medically documented mild, moderate, and severe TBI at 12 months postinjury.SettingEighteen participating Level 1 trauma centers in the United States.ParticipantsParticipants with TBI (N=1505) and primary outcome data at 12-month follow-up.InterventionsNot applicable.Main Outcome MeasuresPatient Health Questionnaire-9 (PHQ-9).ResultsPHQ-9 total scores were significantly lower for older adults (age≥65y; M=3.2) compared with younger adults (age<65y; M=5.0; B=?1.63, P<.001), indicating fewer depressive symptoms in older adults. Age did not interact with education, sex, race/ethnicity, psychiatric history, substance use, or Glasgow Coma Scale severity to affect PHQ-9 scores. Of the 29% of older adults who endorsed symptoms consistent with depression, 14% were classified as minor depression and 15% as major depression. The odds of older adults falling in the major depression vs no depression group were significantly lower (decreased by 56%) compared with younger adults (odds ratio=0.44, P=.001).ConclusionsAt 12 months post-TBI, older adults endorse lower depressive symptoms than their younger counterparts and are less likely to experience major depression; however, over one-fourth of older adults endorsed symptoms consistent with depression, warranting evaluation and treatment.     

Combining robotic exoskeleton and body weight unweighing technology to promote walking activity in tetraplegia following SCI: A case study

Context: To investigate the feasibility of combining the lower-limb exoskeleton and body weight unweighing technology for assisted walking in tetraplegia following spinal cord injury (SCI).

Findings: A 66-year-old participant with a complete SCI at the C7 level, graded on the American Spinal Injury Association Impairment Scale (AIS) as AIS A, participated in nine sessions of overground walking with the assistance from exoskeleton and body weight unweighing system. The participant could tolerate the intensity and ambulate with exoskeleton assistance for a short distance with acceptable and appropriate gait kinematics after training.

Conclusion: This report showed that using technology can assist non-ambulatory individuals following SCI to stand and ambulate with assistance which may promote general physical and psychological health if used in the long term.     

Motor unit number index and compound muscle action potential amplitude

ObjectivesMUNIX (motor unit number index), derived from the compound muscle action potential (CMAP) and surface EMG interference pattern (SIP) has become popular as a substitute for motor unit number estimation (MUNE). This study was undertaken to determine why, in recent recordings from amyotrophic lateral sclerosis (ALS) patients and healthy controls, we found that MUNIX values resembled CMAP amplitudes more closely than MUNE values.MethodsThe relationship between MUNIX and CMAP and SIP amplitudes was investigated by a theoretical analysis and by reanalysing the data from the previous study.ResultsTheory indicates that when motor unit potentials overlap extensively, information about motor unit size and number is lost, and MUNIX depends only on CMAP area and power. Accordingly, MUNIX values were found to be sensitive to changes in CMAP amplitude but insensitive to changes in SIP amplitude. The reproducibility of MUNIX measurements in healthy controls was found to depend almost entirely on correlation with CMAP properties.ConclusionsMUNIX gives misleading information about motor unit numbers in healthy controls, and provides little information about loss of motor units in ALS patients beyond that given by simple CMAP amplitude measurements.SignificanceMUNIX should not be interpreted as a MUNE method.     

Effect of a Fascial Therapy Treatment on Quality of Life in Patients With Hemophilic Elbow Arthropathy: A Randomized Controlled Trial

ObjectiveTo evaluate the effect of fascial therapy on the perceived quality of life, pain intensity, and joint health in people with hemophilia.DesignSingle-blind randomized controlled trial.SettingHemophilia Patient Associations.ParticipantsPatients with hemophilia (N=69) were randomly allocated to an experimental group (fascial therapy protocol) or to a control group (no intervention whatsoever).InterventionsThe fascial therapy intervention lasted 3 consecutive weeks with one 45-minute weekly session.Main Outcome MeasuresThe variables evaluated were perceived quality of life (Short Form Health Survey-36), pain intensity (visual analog scale) and joint health (Hemophilia Joint Health Score) at baseline and at 3 and 12 weeks.ResultsThe mean values of the physical (38.64±9.41 and 41.92±12.16) and mental (45.77±6.25 and 55.02±9.73) components of the Short Form Health Survey-36 improved after the intervention in the experimental group, as well as those for pain intensity and joint health (P<.001). There were differences (P<.001) in the intergroup effect in the physical role variables (F=49.22), emotional role (F=229.71), mental component (F=9.86), intensity of pain (F=24.74), and joint health (F=55.31).ConclusionsA fascial therapy protocol for patients with hemophilic elbow arthropathy can improve their perceived quality of life. Elbow pain intensity improved in patients treated with fascial therapy. This technique can improve elbow joint health.
