Item type:Publication, Finger and wrist rehabilitation system based on soft robotics(Springer Science+Business Media, 2025-10-01)Soft robotics have been shown to offer benefits in physical hand rehabilitation therapies. However, most existing proposals focus solely on adults, neglecting the distinct biomechanical characteristics of children. Moreover, these proposals focus on systems designed for either finger or wrist rehabilitation, overlooking that effective hand rehabilitation therapies requires coordinated movements of fingers and the wrist. Accordingly, this study presents the design, simulation, and validation of a pediatric rehabilitation system that enables finger pulp pinch and wrist flexion–extension movements. The actuator design process considers the biomechanical characteristics of children. The actuators are constructed using a material rarely mentioned in the literature: RTV type 6 — Silika Moldes e Insumos. The mechanical tests are performed in accordance with the ASTM D412 standard to simulate it using finite element analysis in ANSYS software. The ANSYS fitting source is used to extract material coefficients from the fitted Yeoh model. Subsequently, the manufacturing of both actuators is described in detail, followed by testing using a proposed pneumatically controlled system. Our comprehensive experimental validation tests evaluate the actuators’ force output, kinematic hysteresis, fatigue, maximum breaking point, and safety factors, ensuring confidence in the system’s performance. Finally, a prototype of the finger and wrist rehabilitation system is presented.3 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evaluation of wrist and finger function in healthy children through music-based video game therapy(BioMed Central Ltd, 2025-12-01)BACKGROUND: The loss of hand and wrist function significantly impairs an individual's ability to perform everyday tasks, resulting in reduced independence and a lower quality of life. Neurological disorders, such as cerebral palsy, are among the leading causes of such impairments. These conditions often lead to difficulties with muscle strength, coordination, and motor control, impacting an individual's ability to manipulate objects. Cerebral palsy is a prevalent neurological disorder in children that often causes severe impairments in hand and wrist function. Traditional rehabilitation methods, such as physiotherapy, are effective but often suffer from poor adherence, especially in pediatric populations. Therefore, the use of engaging interventions, such as music-based and game-based therapies, holds significant promise for improving therapy adherence and effectiveness in children with cerebral palsy. METHODS: The proposed rehabilitation system integrates a wearable data glove with a music-based serious game to promote hand and wrist function in children with neurological impairments. The data glove, equipped with two inertial measurement unit sensors, detects hand and wrist movements, serving as the primary input device for the game. The game design incorporates music therapy elements, including metronome-based rhythms and volume feedback to motivate movement and enhance neuroplasticity. Three distinct games are designed to target wrist flexion and extension, ulnar and radial deviation, and gross motor grip. RESULTS: Ten healthy pediatric participants completed all sessions under both music and no-music conditions. As the data were non-normal, the Wilcoxon signed-rank test was used. Statistically significant differences were found in all games, although effect sizes were small. These results suggest that music may subtly modulate motor performance. For example, in the Rocket game, music reduced variability and range of motion, suggesting more controlled wrist flexion/extension. In the Squirrel and Bubble games, music contributed to smoother movements and greater consistency in pinch grip, respectively. Usability survey data revealed high levels of user satisfaction and enjoyment, with items related to clarity, comfort, engagement, and particularly relaxation showing significant differences above neutral ([Formula: see text]). CONCLUSIONS: This study provides exploratory evidence supporting the feasibility of music-based, game-driven rehabilitation tools in pediatric populations. Although the observed effects were modest, the system demonstrated high usability and acceptability. Future studies should include clinical populations, assess longer-term retention effects, and further investigate how music-induced relaxation may support engagement and treatment adherence in rehabilitation contexts.7
