The effects of anxiety and dual-task on upper limb motor control of chronic stroke survivors

This study was designed to investigate the effects of anxiety and dual-task on reach and grasp motor control in chronic stroke survivors compared with age- and sex-matched healthy subjects (HC). Reach and grasp kinematic data of 68 participants (high-anxiety stroke (HA-stroke), n = 17; low-anxiety stroke (LA-stroke), n = 17; low-anxiety HC, n = 17; and high-anxiety HC, n = 17) were recorded under single- and dual-task conditions. Inefficient reach and grasp of stroke participants, especially HA-stroke were found compared with the control groups under single- and dual-task conditions as evidenced by longer movement time (MT), lower and earlier peak velocity (PV) as well as delayed and smaller hand opening. The effects of dual-task on reach and grasp kinematic measures were similar between HCs and stroke participants (i.e., increased MT, decreased PV that occurred earlier, and delayed and decreased hand opening), with greater effect in stroke groups than HCs, and in HA-stroke group than LA-stroke group. The results indicate that performing a well-learned upper limb movement with concurrent cognitive task leads to decreased efficiency of motor control in chronic stroke survivors compared with HCs. HA-stroke participants were more adversely affected by challenging dual-task conditions, underlying importance of assessing anxiety and designing effective interventions for it in chronic stroke survivors. © 2020, The Author(s)

Increasing mothers� confidence and ability by creating opportunities for parent empowerment (COPE): A randomized, controlled trial

Objectives Premature neonates are at great risk for cerebral palsy, developmental delays, hearing problems and visual impairments. Interventions to reduce the morbidities and adverse health outcomes in these neonates and improve parent-infant interaction are highly important. This study was conducted to determine the effect of the Creating Opportunities for Parent Empowerment (COPE) program on the perceived maternal parenting self-efficacy of premature parents. Materials & Methods This was a randomized controlled trial with equal randomization (1:1:1 for 3 groups) and parallel group design. Forty-five preterm neonates were randomly allocated to treatment (n=15), supervision (n=15) and control (n=15) groups. COPE program was provided in the form of a 4-phase educational-behavioral intervention to the treatment and supervision groups. The primary outcome was parental self-efficacy, which was assessed by the Perceived Maternal Parenting Self-Efficacy inventory. All the measurements were performed pre-and post-completion with the valid equipment and by blind assessors. Results COPE mothers reported significantly stronger beliefs regarding their parental role and have more confidence to their ability in caring of neonates compared with control mothers (P-value <0.001). Conclusion An educational-behavioral intervention would strengthen mothers� belief in themselves and knowledge about their neonates and would enhance premature mothers� ability to care for their neonates as well as parent-infant interaction. © 2020, Iranian Child Neurology Society.
