A single nucleotide polymorphism (SNP) in the catechol-o-methyltransferase (<i>COMT</i>) gene, Val158Met (rs4680), influences cognition in the general population. However, its role in stroke recovery is unclear. In this study, we evaluated the association of Val158Met SNP with stroke functional outcome and recovery. <i>Methods</i>. This is a retrospective study. The MGB Biobank was queried for 570 individuals with stroke and available genomics data. A subset of 164 was curated based on their admission to Spaulding Rehabilitation Hospital (SRH) for inpatient rehabilitation, meeting inclusion/exclusion criteria and receiving a rehabilitation program tailored to their individual needs and goals. Functional independent measures (FIM) were assessed upon admission to SRH and discharge. Multiple tests were performed to identify related clinic characteristics associated with functional outcome, recovery, and independence dichotomization. Logistic and linear regression models adjusted for covariate variables were used to evaluate the association between <i>COMT</i> Val58Met and functional outcome and recovery. <i>Results</i>.

Baseline (BL) and post-intervention (POST) gait responses to tempo increase were assessed as participants walked with the system in a clinic hallway. Rhythm tempo, entrainment, cadence, stride length, gait speed, and stride time variability (STV) were measured during the first minute (tempo at preferred walking cadence, prior to increase) and fifth minute (tempo above preferred cadence, following increase) of each assessment. Within- and between-assessment responses of entrainment and spatiotemporal variables to tempo increase were evaluated. <i>Results.</i> During each assessment, participants entrained to rhythmic cues while significantly increasing their cadence and stride length in response to tempo increase.

Conventional physical therapy following neurological injury is an arduous task met with minimal returns and quickly plateauing recovery. Unconventional therapies, such as robotic assisted gait training (RAGT) have not produced the robust clinical gains that we all had hoped. Rodent RAGT is a nascent field, but it works on the same principles as the clinical counterpart. <i>Objective</i>. We have previously investigated the ability of RAGT to enhance the recovery of rats following a cervical spinal cord injury and found that training in a resistive field is detrimental, and training in a negative viscosity field is better than actively guiding the limbs through a healthy stepping pattern. Unfortunately, none of these treatments are particularly good at restoring unassisted overground locomotion. Previously we grouped animals based on the RAGT treatment they received. Upon further reflection, these groups are not based on what the animals actually experienced, but how the robot was programmed. <i>Methods</i>. In the work presented here we regrouped and reanalyzed our existing data bi-directionally (does level of overground recovery predict RAGT force profile experienced? does force profile predict recovery?). <i>Results</i>. This method allowed us to uncover a training force profile that optimized overground recovery, specifically, low overall forces (<±6 N), positive <i>Fy</i> and negative <i>Fx</i> during swing, and minimal forces during stance (<±2 N). <i>Conclusions</i>.

Participants moved their paretic hands through complex tracks, with 2080 trials in 4 sessions within a week. Speed and accuracy were manipulated by displaying 5 cm-wide or 1.25 cm-wide tracks or providing feedback based on average speed and accuracy in the Speed and Accuracy groups, respectively. We measured changes in kinematics in a 3-target test, in the speed-accuracy trade-off in a modified Fitts' test of the paretic arm during goal-directed reaching, and clinical outcomes (ie, UE Fugl-Meyer, Action Research Arm Test, and Box and Block Test) at 3 days and 1-month post-training.ResultsSpeed training led to significantly faster and smoother movements with more symmetric reach velocity profiles at the 3-day post-test, consistent with better feedforward control.

At 1 month, however, most gains in the 3-target test and in the modified Fitts' test were lost.ConclusionSpeed training led to greater gains in kinematics of goal-directed actions than accuracy training, notably in a 3-day post-test.

Sleep health/disruptions were assessed via patient reports, actigraphy, and biometric sensors. Functional outcomes were measured at admission and discharge. Generalized Linear Models (GLMs) were used to describe changes in sleep health over time, and multivariate regressions analyzed sleep disruptions and sleep-related predictors of functional recovery.ResultsOver inpatient stays, sleep improved with a 23% reduction in wake after sleep onset and 15% fewer multiple overnight disruptions.

Poor initial sleep quality and cognitive status were associated with more overnight disruptions. Lastly, minimal associations were found between sleep health and functional recovery.ConclusionsSleep health during inpatient stroke rehabilitation is generally poor, though improves over time. Sleep is affected by neurological recovery and hospital environment.

This study first described heterogeneity of change in cognitive processing speed (CPS) across the intervention conditions and then identified possible adherence/compliance, baseline performance, and demographic/clinical variables as correlates of rehabilitation-related CPS changes.MethodsA total of 311 persons with progressive MS who were pre-screened for impaired CPS completed 12 weeks of combined cognitive rehabilitation (or sham) and exercise training (or sham). CPS was measured before and after the 12-week period. As potential correlates of CPS changes, we measured adherence/compliance (ie, treatment exposure), performance outcomes at baseline, as well as demographic and clinical characteristics at baseline.ResultsThere was heterogeneity of change in CPS across the 4 intervention conditions. We further identified baseline learning and memory impairment and premorbid intelligence quotient (IQ), but not adherence/compliance, other baseline performance outcomes, or demographic/clinical characteristics as significant correlates of CPS changes across the 4 intervention conditions.ConclusionsThe overall pattern of results suggests that future trials in this area might account for impaired learning and memory and/or premorbid IQ as potential covariates, or more carefully consider the role of reserve within rehabilitation interventions in progressive MS.</p>","PeriodicalId":94158,"journal":{"name":"Neurorehabilitation and neural repair","volume":" ","pages":"15459683251331586"},"PeriodicalIF":0.0,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
