UNLABELLED BACKGROUND The purpose of this study was to assess the concurrent validity of alternative measures of frontal plane knee alignment, namely the radiographic anatomic axis and two clinical measures in patients complaining of knee malalignment as compared with the mechanical axis on full-length radiograph of lower limbs. METHODS The knee-alignment angle was measured in 100 knees of...
OBJECTIVE To introduce the "virtual goniometer", a method of measuring angles on digital images using Microsoft PowerPoint, a readily available and inexpensive software programme. METHODS Twenty-six X-rays of scoliosis curves were photographed with a digital camera. Six examiners measured the angles of curvature on their computers using the goniometer (Set 1). Under a blinded protocol, repeat...
OBJECTIVE To determine whether there are differences in results when evaluating cervical range of motion (ROM) with radiographic analysis, a bubble goniometer, and a dual inclinometer and whether particular physical parameters are related to cervical ROM. METHODS We evaluated the cervical ROM of 115 volunteers with each of the 3 clinical methods. Tape measurements of neck girth, distance from...
BACKGROUND Adequate sagittal plane motion of the first metatarsalphalangeal joint (1st MTPJ) is important during normal gait and goniometric measurement is commonly used as a diagnostic and outcome assessment tool. We aimed to determine the intra and inter-rater reliability together with the concurrent validity of a universal plastic goniometer (UG) and a smartphone applicationlication (Dr G) f...
A light-scattering goniometer for evanescent-wave dynamic light scattering (EWDLS) measurements at a liquid-fluid interface is introduced, and used for measurements on two charge-stabilized polystyrene colloid systems adsorbed to alkane-water interfaces. The goniometer allows an independent variation of the penetration depth and the scattering vector components parallel and perpendicular to a l...
The purpose of this study was to compare knee extension range of motion (ROM) as measured by a newly constructed linear instrument and by a gravity goniometer among children ages 8-14 years and to establish normative values for these children. The linear instrument recorded the distance in millimeters from the border of an uplifted heel to the measurement table. Coefficients of variation for kn...
The Parallel Robotics Inspired Goniometer (PRIGo) is a novel compact and high-precision goniometer providing an alternative to (mini-)kappa, traditional three-circle goniometers and Eulerian cradles used for sample reorientation in macromolecular crystallography. Based on a combination of serial and parallel kinematics, PRIGo emulates an arc. It is mounted on an air-bearing stage for rotation a...
