Intratest reliability in determining the subtalar joint axis using the palpation technique described by K. Kirby Universiteit Gent
A pressure algometer is a useful tool to objectively monitor the effect of diagnostic palpation by a physiotherapist in Warmblood horses Universiteit Gent
Spinal Palpation Error and Its Impact on Skin Marker-Based Spinal Alignment Measurement in Adult Spinal Deformity KU Leuven
Spinal alignment measurement in spinal deformity research has recently shifted from using mainly two-dimensional static radiography toward skin marker-based motion capture approaches, allowing three-dimensional (3D) assessments during dynamic conditions. The validity and accuracy of such skin marker-based methods is highly depending on correct marker placement. In this study we quantified, for the first time, the 3D spinal palpation error in ...
Towards Palpation in Virtual Reality by an Encountered-Type Haptic Screen KU Leuven
Virtual Reality technology takes in an increasingly prominent role in modern medical training programs. The fidelity of the Virtual Reality environment is of crucial importance and directly relates to the quality of skill transfer. To train interventions that rely on physical interaction with the patient, high-quality haptic feedback should be provided. Palpation is a prototypical example of an important medical skill relying heavily on physical ...
Haptic Feedback for Soft-Tissue Robotic Surgery: from Training Palpation to Haptic Augmentation KU Leuven
Robotic minimally invasive surgery (RMIS) is a field in full development. Since evidence of the benefits of robotic approaches are surfacing the field, RMIS is receiving an increased interest by both academia and industry. There are nevertheless some major hurdles to this technology. Apart from the cost, a major impediment to its adoption is the long learning curve. As in RMIS the surgeon is decoupled from the patient and only interacts through ...
Development and validation of a palpation device for arbitrary muscle stiffness measurements within subjects Universiteit Antwerpen
Objective: Neuromuscular disorders can often be quantified by the amount of muscle activity and is generally measured through electromyography. However, this method cannot provide arbitrary data as it only detects fluctuations in electrical potential. There is a need for arbitrary and standardised assessments of muscle tone to enable physiotherapists to make correct diagnoses. In this work, we present the rationale and results of a newly ...
The haptic desk – towards a more natural interface to train surgical palpation tasks KU Leuven
During surgical palpation, fingers move freely over large surfaces as they are exposed to variations in texture, friction, slip, stiffness, surface deformation and so on. The vast majority of nowadays’ virtual reality trainers are operated through stylus-based haptic display systems. The fidelity of these systems, especially with respect to the rendering of palpation tasks, is limited as these devices literally force the operator to explore the ...
The Subtalar Joint Axis Palpation Technique Part 2: Reliability and Validity Results Using Cadaver Feet KU Leuven Universiteit Antwerpen
BACKGROUND: Clinically locating the point of no rotation to determine the subtalar joint axis location by applying pressure on the plantar surface of the foot was described by Kirby in 1987 but was never validated. We sought to extend a previously validated mechanical model to cadaver feet and to examine the intratester and intertester reliability. METHODS: Four testers with different levels of experience determined the subtalar joint axis ...
The Subtalar Joint Axis Palpation Technique-Part 1 Validating a Clinical Mechanical Model KU Leuven Universiteit Antwerpen Universiteit Gent
BACKGROUND: Locating the position of the subtalar joint axis can be a predictive clinical variable in biomechanical analysis and a valuable tool in the design of functional foot orthoses. Before testing Kirby's palpation technique to locate the subtalar joint axis in cadavers, it was important to develop and test the experimental methods in a mechanical model in which the exact location of the hinge joint can be controlled. METHODS: Four testers ...
