Observation of human joint motion plays an important role in many fields. The results of the human links can provide information about musculoskeletal parameters. Some devices can track real-time joint movement in the human body during essential daily activities, sports, and rehabilitation with memory for storing the information concerning the body. Based on the algorithm for signal features, the collected data can reveal the conditions of multiple physical and mental health issues. This study proposes a novel method for monitoring human joint motion at a low cost. We propose a mathematical model to analyze and simulate the joint motion of a human body. The model can be applied to an Inertial Measurement Unit (IMU) device for tracking dynamic joint motion of a human. Finally, the combination of image-processing technology was used to verify the results of model estimation. Moreover, the verification showed that the proposed method can estimate joint motions properly with reduced-number IMUs.

Baseline characteristics and 2-year functional outcome data of patients undergoing an arthroscopic rotator cuff repair in Switzerland, results of the ARCR_Pred study.
PLoS One
January 2025
Orthopaedic Surgery and Traumatology, University Hospital Basel, Basel, Switzerland.
The ARCR_Pred study was initiated to document and predict the safety and effectiveness of arthroscopic rotator cuff repair (ARCR) in a representative Swiss patient cohort. In the present manuscript, we aimed to describe the overall and baseline characteristics of the study, report on functional outcome data and explore case-mix adjustment and differences between public and private hospitals. Between June 2020 and November 2021, primary ARCR patients were prospectively enrolled in a multicenter cohort across 18 Swiss and one German orthopedic center.

Key Laboratory of Sports Engineering of General Administration of Sport of China, Wuhan Sports University, Wuhan, Hubei Province, China.
Purpose: Previous studies have demonstrated significant biomechanical differences between individuals with chronic ankle instability (CAI) and healthy controls during the Y-balance test. This study aimed to examine the effects of kinesio taping (KT) on lower limb biomechanical characteristics during the Y-balance anterior reach task in individuals with CAI.
Methods: A total of 30 participants were recruited, comprising 15 individuals with CAI and 15 healthy controls.
Rocking Motion Therapy for Delirious Patients in the ICU: A Multicenter Randomized Clinical Trial.
Crit Care Med
November 2024
Department of Intensive Care, Copenhagen University Hospital, Copenhagen, Denmark.
Objectives: Rocking motion therapy has been shown to calm people with dementia but has never been investigated in delirious patients in the ICU. The aim of this clinical trial was to investigate the efficacy and safety of a rocking motion vs. nonrocking motion chair on the duration of delirium and intensity of agitation in ICU patients with delirium.

Background: Sleep disturbances are common and distressing among patients with atopic dermatitis (AD), often resulting in a cycle of worsening skin conditions. Among various factors affecting sleep in AD, cervical spine movement has been suggested to influence sleep quality; however, these studies mostly relied on subjective measures. Owing to the lack of objective and quantitative analyses of cervical spine movement, its association with sleep disturbances remains poorly understood.
