Current models for targeted-tracking are discussed and shown to be inadequate as a means of understanding the combined task of tracking, as in the Drury's paradigm, and having a final target to be aimed at, as in the Fitts' paradigm. It is shown that the task has to be split into components that are, in general, performed sequentially and have a movement time component dependent on the difficulty of the individual component of the task. In some cases, the task time may be controlled by the Fitts' task difficulty, and in others, it may be dominated by the Drury's task difficulty. Based on an experiment carried out that captured movement time in combinations of visually controlled and ballistic movements, a model for movement time in targeted-tracking was developed.

Pain perception, opioid consumption and mobility following lateral compression pelvic ring injuries: a two-year prospective cohort study.
Eur J Orthop Surg Traumatol
January 2025
Department of Trauma Surgery, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.
Purpose: A prospective longitudinal cohort study was performed to gain insight into the course of recovery in terms of pain, opioid consumption, and mobility in patients with a lateral compression (LC) pelvic injury.
Methods: Adult patients with an LC injury, without any cognitive disorders or limited mobility and who could communicate in Dutch were asked to participate. Pain in terms of NRS (numeric rating scale, range 0-10), opioid use and mobility were recorded at eight time points: at hospital admission, and three days, one week, six weeks, three months, six months, one year and two years after the injury.
Accelerative Effects of Transcutaneous Electrical Acustimulation on Postoperative Recovery After Thoracolumbar Vertebral Fracture Associated With Suppressed Sympathetic Activity and Interleukin-6.
Neuromodulation
January 2025
Division of Gastroenterology and Hepatology, University of Michigan School of Medicine, Ann Arbor, MI, USA. Electronic address:
Objectives: Gastrointestinal (GI) disturbance is a frequent complication in patients with thoracolumbar vertebral fracture (TVF). Transcutaneous electrical acustimulation (TEA) has been reported to effectively accelerate postoperative GI function recovery after abdominal surgery. This study aimed to investigate the effects of TEA on postoperative recovery and the associated mechanisms.

J Foot Ankle Res
March 2025
The University of South Australia, Allied Health & Human Performance Unit, Adelaide, SA, Australia.
Background: This study investigated the effect of various offloading devices commonly used for the management of diabetic foot ulcerations on peak plantar pressure and pressure-time integral of the contralateral limb.
Methods: A quantitative, randomised and within-subject repeated measures study was conducted in an outpatient gait laboratory. Outpatients with unilateral diabetic foot ulcers and adequate perfusion to the lower limb without an intrinsic limb-length discrepancy who were able to walk were recruited for the study.
Longitudinal analysis of anthropometric measures over 5 years in patients with Friedreich ataxia in the EFACTS natural history study.
Eur J Neurol
January 2025
Department of Neurology, RWTH Aachen University, Aachen, Germany.
Background: Friedreich ataxia is a rare neurodegenerative disorder caused by frataxin deficiency. Both underweight and overweight occur in mitochondrial disorders, each with adverse health outcomes. We investigated the longitudinal evolution of anthropometric abnormalities in Friedreich ataxia and the hypothesis that both weight loss and weight gain are associated with faster disease progression.

Mov Disord
January 2025
Department of Neurology, LMU University Hospital, Ludwig-Maximilians-Universität (LMU) München, Munich, Germany.
Background: The recent Movement Disorders Society (MDS)-progressive supranuclear palsy (PSP) diagnostic criteria conceptualized three clinical diagnostic certainty levels: "suggestive of PSP" for sensitive early diagnosis based on subtle clinical signs, "possible PSP" balancing sensitivity and specificity, and "probable PSP" highly specific for PSP pathology.
Objective: The aim of this study was to prospectively validate the criteria against long-term clinical follow-up and characterize the diagnostic certainty increase over time.
Methods: Patients with "possible PSP" or "suggestive of PSP" diagnosis and clinical follow-up were recruited in two German multicenter longitudinal observational studies (ProPSP and DescribePSP).
