This qualitative research study was designed to explore and describe the process of planning and performing bimanual activities in young persons with hemiplegic cerebral palsy. Interviews with 10 persons individually and four persons in a focus group provided rich information about their reasoning when confronting problems as well as insight into how they view their situations. The data were analyzed using a comparative method. The findings show that the participants had to make conscious choices about what would be the most effective strategies to use for carrying out activities. The choices involved weighing different options to find the least negative alternative. Even when able to find alternative strategies for performing the activity, the participants were often dissatisfied with negative consequences related to the strategy. Examples of such negative consequences could be, for example, that they would have to accept a need for extra time, planning, or concentration, to perform desired activities. When selecting a strategy it was thus favorable to have a repertoire of strategies from which to choose. In conclusion, the planning and performing of bimanual activities turned out to be a complex process influenced by a range of factors both internal and external to the person.

Importance: To efficiently perform bimanual daily tasks, bimanual coordination is needed. Bimanual coordination is the interaction between an individual's hands, which may be impaired post-stroke, however clinical and functional assessments are lacking and research is limited.
Objectives: To develop a valid and reliable observation tool to assess bimanual coordination of individuals post-stroke.

Background: Correct identification of the epidural space requires extensive training for technical proficiency. This study explores a novel bimanual haptic simulator designed for the precise insertion of an epidural needle based on loss-of-resistance (LOR) detection, providing realistic dual-hand force feedback.
Methods: The simulator, equipped with two haptic devices connected to a Tuohy needle and an LOR syringe, was designed to simulate the tissues' resistive forces felt by the user during the procedure, offer anatomical variability and record detailed performance metrics for personalized feedback.

Hand-arm bimanual intensive therapy (HABIT) enhances upper extremity (UE) function and bimanual coordination in children with unilateral cerebral palsy (UCP). Previous studies assessed immediate improvements in UE function using clinical and self-reported measures, which may not accurately reflect real-world UE performance and their long-term retention effects. Therefore, this study aims to investigate the retention of real-world bimanual performance gains over time following HABIT in children with UCP.

In the rubber hand illusion (RHI), individuals perceive a fake hand as their own if an unseen hand and a visible fake hand are stroked simultaneously. We examined how the RHI on either hand influenced the temporal order judgment (TOJ) of bimanual stimulation. In Experiment 1, participants performed TOJ during RHI or non-RHI conditions.

Action-imagery-practice refers to the repetitive use of action imagery to improve subsequent performance leading to partially different representation types than action-execution-practice (AEP). This study explored the representation types in kinesthetic action-imagery-practice (K-AIP) and visual action-imagery-practice (V-AIP) in a serial reaction time task using the crossed hand transfer paradigm. 169 participants (age M ± SD = 25.
