A parametric 3D printed assistive device for people with cerebral palsy - assessment of outcomes and comparison with a commercial counterpart.

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.

From patient to maker - a workflow including people with cerebral palsy in co-creating assistive devices using 3D printing technologies.

Purpose: Digital fabrication, like 3D printing, is a new opportunity for rehabilitation professionals to produce customized assistive devices. It allows for empowerment and collaboration in device procurement, but practical implementations are scarcely described. We describe the workflow, discuss feasibility and propose directions for future work.

Photon efficient orientation estimation using polarization modulation in single-molecule localization microscopy.

Combining orientation estimation with localization microscopy opens up the possibility to analyze the underlying orientation of biomolecules on the nanometer scale. Inspired by the recent improvement of the localization precision by shifting excitation patterns (MINFLUX, SIMFLUX), we have adapted the idea towards the modulation of excitation polarization to enhance the orientation precision. For this modality two modes are analyzed: i) normally incident excitation with three polarization steps to retrieve the in-plane angle of emitters and ii) obliquely incident excitation with p-polarization with five different azimuthal angles of incidence to retrieve the full orientation.

The Impact of Post-Thyroidectomy Neck Stretching Exercises on Neck Discomfort, Pressure Symptoms, Voice and Quality of Life: A Randomized Controlled Trial.

Background: Following surgery for benign nodular goiter, patients may experience neck and shoulder pain, neck pressure and tightness, choking sensation, altered voice function, and dysphagia leading to decreased short-term quality of life (QoL). This single-blinded randomized controlled trial investigated the effect of post-thyroidectomy rehabilitative neck stretching and movement exercises on these variables including QoL.

Methods: Patients undergoing thyroid lobectomy or total thyroidectomy were randomized to perform neck stretching and movement exercises three times daily in four weeks following surgery (intervention group) or conventional follow-up without exercises (control group).
