Effect of Stroke on Joint Control during Reach-to-Grasp: A Preliminary Study.
Effect of Stroke on Joint Control during Reach-to-Grasp: A Preliminary Study. J Mot Behav. 2019 May 20;:1-17 Authors: Raj S, Dounskaia N, Clark WW, Sethi A Abstract We investigated changes in control of inter-segmental dynamics underlying upper extremity dyscoordination caused by stroke. Individuals with stroke and healthy individuals performed a natural reach-to-grasp movement. Kinetic analysis revealed that both groups rotated the shoulder by muscle torque and used interaction torque to rotate the elbow. However, individuals with stroke used interaction torque less than healthy individuals, actively suppressing a substantial portion of it. This resulted in inefficient use of active control and dyscoordination of the upper extremity. The degree of interaction torque suppression and inefficiency of active control at the elbow positively correlated with stroke severity. The increased interaction torque suppression can be a strategy used by individuals with stroke to compensate for deficient feedforward control of this torque.

His brand is crisis, so it can be hard to keep abreast of the various calamities President Trump stumbles into or deliberately courts. Now that tensions with Iran seem to have momentarily cooled, another recent episode of Trumpian brinksmanship, closer to home, deserves some attention before we lurch forward into new dangers. As you ’ve surely heard, but may have already forgotten amid the fog of near-war, three weeks ago, President Trump threatened to declare yet another national emergency at the southern border. If Mexico didn’t sufficiently crack down on cross-border migration,Trump warned, he ’d...
DR M ASHRAF MANSOUR (Grand Rapids, MI): Dr Mayor and colleagues queried the National Inpatient Sample (NIS) for carotid interventions between 2005 and 2015. They stopped collecting data after October 2015 because we switched to ICD-10 and they were afraid of contaminating their data. They found more than 1,242,000 patients in this database. These patients received either carotid endarterectomy or stent. Roughly 41.5% were women. Interestingly, only 11.3% were symptomatic. Their studies showed the highest rate of stroke in their patients was in symptomatic women having a carotid stent, followed by symptomatic women having an endarterectomy.

Conclusions: We found no association between weekend admission and 30-day readmissions, providing indirect evidence of homogeneity in the quality of care delivered during week day and weekend admissions.Cerebrovasc Dis Extra 2019;9:66 –71

CONCLUSIONS: It appears that cycling has a positive effect on walking speed, walking ability and balance. Functional electrical stimulation combined with cycling has positive effects on balance beyond cycling alone. PMID: 31227660 [PubMed - in process]
CONCLUSIONS: Neurological patients showed a misperception of the verticality, estimated using the SVV. The neurological pathology that most alters the SVV is stroke. PMID: 31227659 [PubMed - in process]
CONCLUSIONS: Multiple sessions of STT practice can improve paretic arm function and decrease TCI bilaterally, with no additional benefit of prior cTBS. Our results suggest that improvement in STT practice following M1c cTBS scaled with change in paretic arm function in some individuals. Our results highlight the need for a better understanding of the mechanisms of cTBS to effectively identify who may benefit from this form of brain stimulation. PMID: 31227676 [PubMed - in process]
This study aimed to assess the time course of hemodynamic patterns of cortical sensorimotor areas using functional near infrared spectroscopy (fNIRS) and motor recovery within three months after a stroke. METHOD: Eight right-handed first ischemic/hemorrhagic stroke patients (60±8 years, 3 women) with mild to severe hemiparesis were examined with repetitive fNIRS measurements and motor recovery tests (Fugl-Meyer score) during two months. Hemodynamic changes over the ipsilesional and contralesional sensorimotor areas were collected from a multi-channel fNIRS system during intermittent isometric muscle contractions...
CONCLUSIONS: In this pilot study, repeated sessions of bi-hemispheric tDCS coupled with resistance training were found safe and tolerable for individuals at the chronic phase post-stroke. However, the use of tDCS did not result in additional sensorimotor improvements when compared to sham-tDCS. Further research is needed to better assess the clinical benefits of combining non-invasive transcranial stimulation with rehabilitation after a stroke.
