Single‐Operator Stress Ultrasound Evaluation of Ulnohumeral Joint Instability Related to Medial Ulnar Collateral Ligament Injury

Journal of Ultrasound in Medicine, EarlyView.
This article introduces a novel, single‐operator stress ultrasound technique for evaluating medial ulnar collateral ligament (MUCL) integrity by assessing medial ulnohumeral joint (MUHJ) widening under valgus stress. Unlike prior methods requiring dual operators, specialized equipment, or the use of hand/wrist weights, this approach was designed for ...

Low-Cost Dynamometer for Measuring and Regulating Wrist Extension and Flexion Motor Tasks in Electroencephalography Experiments

Sensors
A brain–computer interface could control a bionic hand by interpreting electroencephalographic (EEG) signals associated with wrist extension (WE) and wrist flexion (WF) movements. Misinterpretations of the EEG may stem from variations in the force, speed

Age, sex and graft choice are associated with the achievement of a patient acceptable symptom state five years after primary ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine the proportion of patients and the factors associated with the achievement of a patient‐acceptable symptom state (PASS) 5 years after primary anterior cruciate ligament reconstruction (ACLR). Methods Patients who underwent primary ACLR between 2005 and 2018 at Capio Artro Clinic, Stockholm, Sweden, were eligible for ...

Similar dynamic tibiofemoral movements during jump‐landing and walking but distinct hamstrings strength across ACL reconstruction autograft types at mid‐term follow‐up

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Dynamic tibiofemoral movements following anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autografts have not yet been compared to other autografts. We aimed to compare dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing and walking among patients with QT, bone ...
