Validity and Test-Retest Reliability of Spatiotemporal Running Parameter Measurement Using Embedded Inertial Measurement Unit Insoles.

Running is the basis of many sports and has highly beneficial effects on health. To increase the understanding of running, DSPro® insoles were developed to collect running parameters during tasks. However, no validation has been carried out for running gait analysis. The aims of this study were to assess the test-retest reliability and criterion validity of running gait parameters from DSPro® insoles compared to a motion-capture system. Equipped with DSPro® insoles, a running gait analysis was performed on 30 healthy participants during overground and treadmill running using a motion-capture system. Using an intraclass correlation coefficient (ICC), the criterion validity and test-retest reliability of spatiotemporal parameters were calculated. The test-retest reliability shows moderate to excellent ICC values (ICC > 0.50) except for propulsion time during overground running at a fast speed with the motion-capture system. The criterion validity highlights a validation of running parameters regardless of speeds (ICC > 0.70). This present study validates the good criterion validity and test-retest reliability of DSPro® insoles for measuring spatiotemporal running gait parameters. Without the constraints of a 3D motion-capture system, such insoles seem to be helpful and relevant for improving the care management of active patients or following running performance in sports contexts.

3D motion analysis dataset of healthy young adult volunteers walking and running on overground and treadmill.

Used on clinical and sportive context, three-dimensional motion analysis is considered as the gold standard in the biomechanics field. The proposed dataset has been established on 30 asymptomatic young participants. Volunteers were asked to walk at slow, comfortable and fast speeds, and to run at comfortable and fast speeds on overground and treadmill using shoes. Three dimensional trajectories of 63 reflective markers, 3D ground reaction forces and moments were simultaneously recorded. A total of 4840 and 18159 gait cycles were measured for overground and treadmill walking, respectively. Additionally, 2931 and 18945 cycles were measured for overground and treadmill running, respectively. The dataset is presented in C3D and CSV files either in raw or pre-processed format. The aim of this dataset is to provide a complete set of data that will help for the gait characterization during clinical gait analysis and in a sportive context. This data could be used for the creation of a baseline database for clinical purposes to research activities exploring the gait and the run.

IMPROVE study protocol, investigating post-stroke local muscle vibrations to promote cerebral plasticity and functional recovery: a single-blind randomised controlled trial.

INTRODUCTION: Spasticity is a frequent disabling consequence following a stroke. Local muscle vibrations (LMVs) have been proposed as a treatment to address this problem. However, little is known about their clinical and neurophysiological impacts when used repeatedly during the subacute phase post-stroke. This project aims to evaluate the effects of a 6-week LMV protocol on the paretic limb on spasticity development in a post-stroke subacute population. METHODS AND ANALYSIS: This is an interventional, controlled, randomised, single-blind (patient) trial. 100 participants over 18 years old will be recruited, within 6 weeks following a first stroke with hemiparesis or hemiplegia. All participants will receive a conventional rehabilitation programme, plus 18 sessions of LMV (ie, continuously for 30 min) on relaxed wrist and elbow flexors: either (1) at 80 Hz for the interventional group or (2) at 40 Hz plus a foam band between the skin and the device for the control group.Participants will be evaluated at baseline, at 3 weeks and 6 weeks, and at 6 months after the end of the intervention. Spasticity will be measured by the modified Ashworth scale and with an isokinetic dynamometer. Sensorimotor function will be assessed with the Fugl-Meyer assessment of the upper extremity. Corticospinal and spinal excitabilities will be measured each time. ETHICS AND DISSEMINATION: This study was recorded in a clinical trial and obtained approval from the institutional review board (Comité de protection des personnes Ile de France IV, 2021-A03219-32). All participants will be required to provide informed consent. The results of this trial will be published in peer-reviewed journals to disseminate information to clinicians and impact their practice for an improved patient's care.
