Human passive neck stiffness and range of motion (20-79 years) Resource Materials: moment-angle data

<p dir="ltr">This dataset contains anthropometry and moment-angle data collected for 80 participants, in a study of passive neck stiffness and range of motion. Participants were aged 20 to 79 years.</p><p dir="ltr">Files are grouped into .zip folders, named by [sex][decade-age-group]. </p><p dir="ltr">Files are in .xlsx format; there is one file per participant.</p><p dir="ltr">File names follow the format [sex][decade-age-group]_[participant number], where:</p><p dir="ltr"><b>Sex:</b></p><p dir="ltr">o M: male</p><p dir="ltr">o F: female</p><p dir="ltr"><b>Decade-age-group:</b></p><p dir="ltr">o 2: 20 to 29 years</p><p dir="ltr">o 3: 30 to 39 years</p><p dir="ltr">o 4: 40 to 49 years</p><p dir="ltr">o 5: 50 to 59 years</p><p dir="ltr">o 6: 60 to 69 years</p><p dir="ltr">o 7: 70 to 79 years</p><p dir="ltr"><b>Participant number</b> is numeric, 1-10, with up to 10 participants in each sex and decade-age-group combination.</p><p dir="ltr">“Sheet1” in each file contains anthropometric information for the participant, including age, sex, body height and mass, head girth (passing through glabella and opisthocranion), neck girth (passing through C4) and dominant hand.</p><p dir="ltr">Subsequent sheets contain moment-angle data for individual trials. The first column (angle) represents the head-torso rotational angle in the tested direction, measured in degrees. The second column (moment) contains the applied moment on the participant’s neck, in units of Nm/degree. Sheets are named by the trial name, following the format: ‘[motion]passive[trial number], where:</p><p dir="ltr"><b>Motion:</b></p><p dir="ltr">o Flexion: flexion</p><p dir="ltr">o Extension: extension</p><p dir="ltr">o Left: left lateral bending</p><p dir="ltr">o Right: right lateral bending</p><p dir="ltr">o Rot_left: left axial rotation</p><p dir="ltr">o Rot_right: right axial rotation</p><p dir="ltr"><b>Trial number</b>: 1-3, corresponding to trials 1 through 3.</p><p dir="ltr">Comprehensive details on the testing protocol, data collection procedures, post-processing methods and trial exclusion criteria (excluded trials are not provided in this Figshare dataset) can be found in the manuscript: </p><p dir="ltr">Liu M, Quarrington RD, Robertson WSP, Sandoz B, Jones CF.
