The Use of Embedded IMU Insoles to Assess Gait Parameters: A Validation and Test-Retest Reliability Study.

ABSTRACT: Wireless wearable insoles are interesting tools to collect gait parameters during daily life activities. However, studies have to be performed specifically for each type of insoles on a big data set to validate the measurement in ecological situations. This study aims to assess the criterion validity and test-retest reliability of gait parameters from wearable insoles compared to motion capture system. Gait of 30 healthy participants was recorded using DSPro^® insoles and a motion capture system during overground and treadmill walking at three different speeds. Criterion validity and test-retest reliability of spatio-temporal parameters were estimated with an intraclass correlation coefficient (ICC). For both systems, reliability was found higher than 0.70 for all variables (p < 0.001) except for minimum toe clearance (ICC < 0.50) with motion capture system during overground walking. Regardless of speed and condition of walking, Speed, Cadence, Stride Length, Stride Time and Stance Time variables were validated (ICC > 0.90; p < 0.001). During walking on treadmill, loading time was not validated during slow speed (ICC < 0.70). This study highlights good criterion validity and test-retest reliability of spatiotemporal gait parameters measurement using wearable insoles and opens a new possibility to improve care management of patients using clinical gait analysis in daily life activities.

Project description:BackgroundMobility and cognitive impairments in Parkinson's disease (PD) often coexist and are prognostic of adverse health events. Consequently, assessment and training that simultaneously address both gait function and cognition are important to consider in rehabilitation and promotion of healthy aging. For this purpose, a computer game-based rehabilitation treadmill platform (GRP) was developed for dual-task (DT) assessment and training.ObjectiveThe first objective was to establish the test-retest reliability of the GRP assessment protocol for DT gait, visuomotor and executive cognitive function in PD patients. The second objective was to examine the effect of task condition [single task (ST) vs. DT] and disease severity (stage 2 vs. stage 3) on gait, visuomotor and cognitive function.MethodsThirty individuals aged 55 to 70 years, diagnosed with PD; 15 each at Hoehn and Yahr scale stage 2 (PD-2) and 3 (PD-3) performed a series of computerized visuomotor and cognitive game tasks while sitting (ST) and during treadmill walking (DT). A treadmill instrumented with a pressure mat was used to record center of foot pressure and compute the average and coefficient of variation (COV) of step time, step length, and drift during 1-min, speed-controlled intervals. Visuomotor and cognitive game performance measures were quantified using custom software. Testing was conducted on two occasions, 1 week apart.ResultsWith few exceptions, the assessment protocol showed moderate to high intraclass correlation coefficient (ICC) values under both ST and DT conditions for the spatio-temporal gait measures (average and COV), as well as the visuomotor tracking and cognitive game performance measures. A significant decline in gait, visuomotor, and cognitive game performance measures was observed during DT compared to ST conditions, and in the PD-3 compared to PD-2 groups.ConclusionThe high to moderate ICC values along with the lack of systematic errors in the measures indicate that this tool has the ability to repeatedly record reliable DT interference (DTI) effects over time. The use of interactive digital media provides a flexible method to produce and evaluate DTI for a wide range of executive cognitive activities. This also proves to be a sensitive tool for tracking disease progression.Clinical trial registrationwww.ClinicalTrials.gov, identifier NCT03232996.

Project description:BackgroundNeurocognitive testing is an important concussion evaluation tool, but for neurocognitive tests to be useful, their psychometric properties must be well established. Test-retest reliability of computerized neurocognitive tests can influence their clinical utility. The reliability for a commonly used computerized neurocognitive test, CNS Vital Signs, is not well established. The purpose of this study was to examine test-retest reliability and reliable change indices for CNS Vital Signs in a healthy, physically active college population.HypothesisCNS Vital Signs yields acceptable test-retest reliability, with greater reliability between the second and third test administration compared with between the first and second administration.Study designCohort study.Level of evidenceLevel 3.MethodsForty healthy, active volunteers (16 men, 24 women; mean age, 21.05 ± 2.17 years) reported to a clinical laboratory for 3 sessions, 1 week apart. At each session, participants were administered CNS Vital Signs. Outcomes included standard scores for the following CNS Vital Signs domains: verbal memory, visual memory, psychomotor speed, cognitive flexibility, complex attention, processing speed, reaction time, executive functioning, and reasoning.ResultsParticipants performed significantly better on the second session and/or third session than they did on the first testing session on 6 of 9 neurocognitive domains. Pearson r test-retest correlations between sessions ranged from 0.11 to 0.87. Intraclass correlation coefficients ranged from 0.10 to 0.86.ConclusionClinicians should consider using reliable change indices to account for practice effects, identify meaningful score changes due to pathology, and inform clinical decisions.Clinical relevanceThis study highlights the importance of clinicians understanding the psychometric properties of computerized neurocognitive tests when using them in the management of sport-related concussion. If CNS Vital Signs is administered twice within a small time frame (such as 1 week), athletes should be expected to improve between the first and second administration.
