Synchronized EMG and motion capture data set for five normally developed subjects performing hand-to-nape with right upper extremity.

Robert Quinton, Elizabeth Rapp van Roden, James Richards, Kristen Nicholson & Tyler Richardson
This study is the first of its kind to utilize synchronized EMG and motion capture data to evaluate the timing and amplitude of all twenty muscle segments influencing scapulothoracic (ST) and glenohumeral (GH) motion in a group of five typically developed individuals performing five everyday shoulder motions. Certain muscles were divided into segments due to their varying lines of action (i.e. deltoid) or varying innervations (i.e. trapezius). The data set was evaluated for conserved muscle...

The package contains the raw data, which are the reviews performed by the KneeHub team members, and the corresponding statistical analysis.

Jason Halloran, Neda Abdollahi Nohouji, Mhd Ammar Hafez, Thor Besier, Snehal Chokhandre, Shady Elmasry, Donald Hume, Carl Imhauser, Nynke Rooks, Marco Schneider, Ariel Schwartz, Kevin Shelburne, William Zaylor & Ahmet Erdemir
Reproducible research serves as a pillar of the scientific method and is a foundation for scientific advancement. However, estimates for irreproducibility of preclinical science range from 75% to 90%. The importance of reproducible science has not been assessed in the context of mechanics-based modeling of human joints such as the knee, despite this being an area that has seen dramatic growth. Framed in the context of five experienced teams currently documenting knee modeling procedures, the...

Data and code repository for the manuscript: JC Selinger, JL Hicks, RW Jackson, CM Wall-Scheffler, D Chang, and SL Delp. Running in the Wild: Using large-scale wearable data to understand ecological running speed preferences. Current Biology (2022).

Jessica Selinger, Jennifer Hicks, Rachel Jackson, Cara Wall-Scheffler, Derek Chang & Scott Delp
Human runners have long been thought to have the ability to consume a near constant amount of energy per distance traveled regardless of speed, allowing speed to be adapted to particular task demands with minimal energetic consequence. However, recent and more precise laboratory measures indicate that humans may in fact have an energy-optimal running speed. Here we characterize runners’ speeds in a free-living environment and determine if preferred speed is consistent with task or energy...

OKS models

Snehal Chokhandre & Ahmet Erdemir
There is a growing interest in the use of virtual representations of the knee for musculoskeletal research and clinical decision making, and to generate digital evidence for design and regulation of implants. Accessibility to previously developed models and related digital assets can dramatically reduce barriers to entry to conduct simulation-based studies of the knee joint and therefore help accelerate scientific discovery and clinical innovations. Development of models for finite element analysis is a demanding process...

Trajectories of body landmarks in videos of cerebral palsy patients and corresponding clinical labels

Łukasz Kidziński, Bryan Yang, Jennifer Hicks, Apoorva Rajagopal, Scott Delp & Michael Schwartz
Cerebral Palsy (CP) is a neurological disorder that is usually caused by mechanical damage to the brain at or around birth. One of the main symptoms of CP is impaired motor control and development of walking skills. In clinical practice in the US child’s gait is often recorded with a camera and the recording can be used by a doctor for assessment. In this dataset we provide body landmarks (such as positions of knees, elbow,...
