AI Article Synopsis
- The study focuses on how augmented feedback training can help reduce vertical ground reaction forces (vGRF) in female athletes landing from a height, ultimately aiming to prevent ACL tears.
- A total of 147 participants were tested under different conditions, leading to the identification of four response groups, with most athletes showing improvement from training.
- Findings highlight that both initial vGRF levels and the athletes' responses to training are crucial in predicting how well they can benefit from augmented feedback.
Article Abstract
Background And Purpose: Anterior cruciate ligament (ACL) tears often occur due to non-contact mechanisms in landing within females. Impact loading and aberrant landings may be addressed with augmented feedback training. The purpose of this study was to identify which female athletes most readily respond to a single session of augmented feedback to attenuate vGRF, by considering baseline peak vGFR and change in vGRF during training.
Design: Repeated Measures.
Methods: One hundred, forty-seven female athletes landed from 50 cm onto two force platforms with and without augmented feedback of vertical ground reaction force (vGRF), vGRF symmetry, and lower extremity position. Each performed six baseline trials and two sets of six training trials with cues. Following training, athletes completed six post-feedback trials (with no feedback) and six dual-task (transfer) trials where they randomly caught a basketball during landing. Peak vGRF was measured. Mean responses were reported for the sets of six trials. Participants were grouped based on their responses to training. Linear regression was used to indicate how well initial performance and response predicted the final response.
Results: Four groups were identified, with 107 participants showing high baseline ground reaction forces and response to training. Only 23 participants (16.4%) did not respond to training. Baseline vGRF predicted post-feedback vGRF and transfer task vGRF (R2=0.508 and R2=0.400) across all participants. When change in vGRF was assessed following two blocks of augmented feedback training, prediction of responders improved with post-feedback vGRF and transfer vGRF (R2=0.911 and R2=0.761).
Conclusions: The combination of both baseline ground reaction force and response to initial training is more accurate than baseline measures alone in identifying those who respond to training. Assessing initial response to training may be necessary to more accurately identify individuals most likely to benefit from augmented feedback training and who may require further evaluation and training.

Background: Reminiscence therapy through music is a psychosocial intervention with benefits for older patients with neurocognitive disorders. Therapies using virtual or augmented reality are efficient in ecologically assessing, and eventually training, episodic memory in older populations. We designed a semi-immersive musical game called "A Life in Songs," which invites patients to immerse themselves in a past era through visuals and songs from that time period.

Article Synopsis
- Researchers explored how visual feedback on interaction forces enhances the performance of haptic-assisted teleoperation for robotic arms in industrial tasks.
- They developed a new method for providing visual cues in a virtual environment and evaluated it alongside a head-mounted display during experiments focused on dross removal.
- Results demonstrated that both methods improved task performance, with visual cues enhancing safety and the head-mounted display significantly boosting overall performance, leading to higher user acceptance of both approaches.

The traditional apprenticeship model of "see one, do one, teach one" is no longer considered the most effective approach for training surgical trainees. Key factors such as patient safety, increasing trainee numbers, and clinician workload pose significant challenges to surgical training. These pressures have led to the adoption of simulation-based education as an effective adjunct to clinical experience when training future surgeons.
