Spontaneous neurological recovery after stroke is a poorly understood process. The aim of the present article was to test proportional model for upper extremity poststroke and identify clinical characteristics patients who do not fit this model.A change in Fugl-Meyer Assessment Upper Extremity score (FMA-UE) measured within 72 hours at 6 months served define motor recovery. Recovery on FMA-UE predicted using model: ΔFMA-UEpredicted = 0.7·(66 - FMA-UEinitial) + 0.4. Hierarchical cluster...

Background and Objective Favorable prognosis of the upper limb depends on preservation or return voluntary finger extension (FE) early after stroke. The present study aimed to determine effects modified constraint-induced movement therapy (mCIMT) electromyography-triggered neuromuscular stimulation (EMG-NMS) capacity poststroke. Methods A total 159 ischemic stroke patients were included: 58 with a favorable (>10° FE) randomly allocated 3 weeks mCIMT usual care only; 101 an unfavorable 3-week...

Proportional recovery of upper-extremity motor function and aphasia after stroke may suggest common mechanisms for spontaneous neurobiological recovery. This study aimed to investigate if the proportional rule also applies visuospatial neglect (VSN) in right-hemispheric first-ever ischemic patients explored possible underlying mechanisms.Patients with upper-limb paresis VSN were included. Recovery defined as change Letter Cancellation Test (LCT) score at ~8 days 6 months poststroke....

When present, clinical threshold for fitting nor non-fitting would be determined, as well within-subject generalizability upper (UE).Prospective cohort study in which Fugl-Meyer Assessment (FMA)-LE FMA-UE were measured <72 hours 6 months Predicted maximum potential was defined...

The absorption and emission of X-rays in dysprosium-doped yttrium aluminum garnet (YAG:Dy) has produced unexpected thermographic behavior, which is investigated using a combination finite temperature ab initio molecular dynamic simulations, structural characterization, electronic structure calculations X-ray characteristics. Calculated average peak spectra (XAS) from simulations between 300 600 K result intensity loss due to thermalization effects, matching experimentally measured behavior...

The impact of spontaneous neurobiological recovery is still neglected in designing rehabilitation trials early post stroke. We aimed to investigate the timing randomization and prognostic stratification on required sample sizes that are needed reveal significant intervention effects upper limb function at 26 weeks after first-ever ischemic stroke.Sample size calculations were based a cohort study 159 patients, using Fugl-Meyer Assessment Upper Extremity Action Research Arm Test as outcome...

Patients without voluntary finger extension early post-stroke are suggested to have a poor prognosis for regaining upper limb capacity at 6 months. Despite this prognosis, number of patients do regain capacity. We aimed determine the time window return during motor recovery and identify clinical characteristics who, despite an initially show months post-stroke.Survival analysis was used assess (Fugl-Meyer Assessment hand sub item extension≥1). A cut-off ≥10 points on Action Research Arm Test...

Spontaneous motor recovery after stroke appears to be associated with structural and functional changes in the network. The aim of current study was explore time-dependent resting-state (rs) connectivity motor-impaired patients, using rs-functional MRI at 5 weeks 26 post-stroke onset. For this aim, 13 patients from EXPLICIT-stroke Trial age gender-matched healthy control subjects were included. Patients' synergistic paretic upper-limb assessed upper extremity section Fugl-Meyer Assessment...

The slow component of O2 uptake (V˙O2sc) represents a progressive decline in work efficiency during strenuous, constant rate cycling. Although most this "excess" can be explained by factors intrinsic to the exercising muscles, it has been proposed that respiratory muscle may also contribute V˙O2sc response. To date, however, no study provided comprehensive analysis mechanical power breathing (Pb) relation while performing strenuous exercise.The Pb was measured 12 recreational cyclists (24 ±...
