Purpose: The aims of this study were to investigate if/how the presence of lymphedema affects the sensation of the upper limb and to assess whether complex decongestive physiotherapy (CDP) has a favorable impact on sensory testing.
Methods: A total of 27 patients with unilateral stage 2 breast cancer-related lymphedema (BCRL) were included in the study. Bilateral circumferential measurements were taken with a tape measure at different levels. Based on these measurements, limb volumes were determined by summing segment volumes derived from the truncated cone formula. Circumferential measurements and ultrasonographic evaluations (epidermis, dermis, and subcutaneous fat thicknesses) were performed at 10 cm distal to the elbow crease. The Semmes-Weinstein monofilament (SWM), static and moving two-point discrimination, pressure pain threshold (PPT), and tactile localization tests were also applied at the same site. After an initial evaluation, all patients underwent CDP phase 1 program. All the evaluations were repeated at the end of the treatment period.
Results: Before CDP, affected sides had significantly higher values than the unaffected sides in terms of SWM (p < 0.001), static (p = 0.002) and moving (p = 0.011) two-point discrimination, PPT (p = 0.001), and tactile localization (p < 0.001) values. After CDP, SWM (p = 0.002), static (p = 0.009) and moving (p = 0.024) two-point discrimination, PPT (p = 0.014), and tactile localization (p < 0.001) values decreased significantly on the affected sides.
Conclusion: BCRL seems to reduce light touch, static and moving two-point discrimination, PPT, and tactile localization sensations, whereas CDP seems to improve these sensory perceptions in women with BCRL. Ultrasonographic measurements also appear to be promising for prompt and convenient follow-up in the management of BCRL.

Aim: The introduction and increasing popularity of indoor trampoline facilities has seen increases in the incidence of trampoline park injuries (TPIs), particularly amongst the paediatric population. A challenge to the development of effective injury prevention interventions is the limited study pool of detailed activity and outcome data to provide better understanding of the characteristics of injurious events.
Methods: A cross-sectional study of individuals under 16 years of age hospitalised after TPI from November 2018 to December 2021 was conducted.

In weightlifting, quantitative kinematic analysis is essential for evaluating snatch performance. While marker-based (MB) approaches are commonly used, they are impractical for training or competitions. Markerless video-based (VB) systems utilizing deep learning-based pose estimation algorithms could address this issue.

Adopting a postural configuration may be regarded as preparation for the performance of an upcoming movement. However, it is unclear how different postural configurations affect motor performance. The aim of the current study was to examine how body posture - sitting versus standing - influences fast and accurate planar point-to-point hand movements.
