This paper presents the use of a parametric design platform and 3D printing to create personalized assistive devices (ADs) for individuals with cerebral palsy, specifically a fork/spoon holder. Five subjects participated in the study, each receiving a customized device to fit their dominant hand, and they tested both the 3D printed device and a commercially available one. The devices were evaluated based on functionality and satisfaction using two standard clinical questionnaires (IPPA and QUEST 2.0). The results showed that neither the 3D printed nor the commercial device provided substantial benefits, but the questionnaires provided valuable feedback on areas for improvement. The study highlights the need for highly personalized solutions in ADs, which could be addressed by 3D printing. A configurator for generating production files from a parametric model could facilitate personalization, but a large number of model versions should be available to meet individual needs. Future research could explore clinical evaluations and guide the development of efficient and effective frameworks for digital fabrication in terms of clinically feasible AD model sourcing.

Impact of Virtual Reality Task-Oriented Training on Upper Extremity Motor Function in Children With Cerebral Palsy: A Randomised Controlled Trial.
Pediatr Neurol
December 2024
Orthopedics Research Center, Mashhad University of Medical Science, Mashhad, Iran.
Background: This study aims to investigate the effect of a newly developed virtual reality task-oriented training (VR-TOT) video game on upper extremity fine motor function compared with conventional occupational therapy through leap motion in children with spastic hemiplegic cerebral palsy (CP).
Methods: In this double-blind randomized clinical trial, 30 children with spastic hemiplegic CP aged six to 10 years were included and randomly allocated into two groups. During six weeks, 15 patients in the intervention group received VR_TOT-based video game in addition to conventional occupational therapy, whereas 15 patients in the control group received only conventional occupational therapy.

Prediction of cerebral palsy and cognitive delay among high-risk children in a developing nation: A successful early detection programme.

Aim: To determine the feasibility of combining the Hammersmith Infant Neurological Examination (HINE) and General Movements Assessment (GMA) within a standard follow-up schedule to predict developmental outcomes in infants at risk in low- and middle-income countries (LMICs).
Method: A total of 201 Sri Lankan infants (128 male, 73 female) were prospectively assessed with the GMA before 44 weeks (writhing movements) and at 3 to 4 months (fidgeting movements), followed by the HINE at 5 to 6 months. Developmental outcomes were assessed using the Bayley Scales of Infant and Toddler Development, Fourth Edition and clinical assessment after 24 months.
Tranexamic acid in hip and spine surgery for children with cerebral palsy - a PRISMA-compliant scoping review.
Syst Rev
December 2024
Department of Paediatrics, The Royal Children's Hospital, University of Melbourne, 50 Flemington Road, Parkville, VIC, 3052, Australia.
Many children with cerebral palsy (CP) are frail and require major hip and/or spine surgeries associated with substantial blood loss. Tranexamic acid (TXA) is commonly used to reduce blood loss, but there is uncertainty around the optimal dose and timing of administration. There have been reviews in sub-populations and specific dosing regimens, but a broad overview of the available literature is lacking.

Research Institute on Health Sciences (IUNICS-IdISBa), University of the Balearic Islands, Palma de Mallorca, Spain.
Background: Pain in people with cerebral palsy (CP) has been classically underestimated and poorly treated, particularly in individuals with impaired communication skills.
Objective: To analyze changes in different salivary metabolites and pain behavior scales after a painful procedure in adults with CP and adults with typical development.
Methods: Salivary levels of sTNF-α, sIgA, Cortisol, FRAP, ADA and Alpha Amylase, as well as 3 observational pain scales (Wong-Baker, Non-Communicating Adults Pain Checklist and Facial Action Coding System) were assessed before and after an intramuscular injection in 30 Individuals with CP and 30 healthy controls.
