“…One of the features of the treadmill, which can eventually be utilized in conjunction with the Optogait OCS, is the adjustment of its surface in different slopes. In this context, the Optogait OCS has been used in a few studies, mainly during uphill walking and running by healthy individuals [ 13 , 14 , 15 ], though the validity of the system in these conditions remains uncertain. So far, the validity of the Optogait OCS has been established for both over-ground [ 16 , 17 , 18 ] and treadmill walking [ 19 ] and running [ 20 ], but only on level surfaces (0% slope).…”

Modern technology has enabled researchers to analyze gait with great accuracy and in various conditions based on the needs of the trainees. The purpose of the study was to investigate the agreement between systems equipped with optical and capacitive sensors in the analysis of treadmill-based level and sloping gait. The spatiotemporal parameters of gait were measured in 30 healthy college-level students during barefoot walking on 0% (level), −10% and −20% (downhill) and +10% and +20% (uphill) slopes at hiking-related speeds using an optoelectric cell system and an instrumented treadmill. Inter-system agreement was assessed using the Intraclass Correlation Coefficients (ICCs) and the 95% limits of agreement. Our findings revealed excellent ICCs for the temporal and between moderate to excellent ICCs for the spatial parameters of gait. Walking downhill and on a 10% slope demonstrated better inter-system agreement compared to walking uphill and on a 20% slope. Inter-system agreement regarding the duration of gait phases was increased by increasing the number of LEDs used by the optoelectric cell system to detect the contact event. The present study suggests that systems equipped with optical and capacitive sensors can be used interchangeably in the treadmill-based spatiotemporal analysis of level and sloping gait.

Background : Psychophysiological changes are part of post-traumatic stress disorder (PTSD) symptomatology and can signal emotional engagement during psychological treatment. Objectives : The aim of this study was to explore psychophysiological responses during multi‐modular motion‐assisted memory desensitization and reconsolidation (3MDR) therapy. Increased self-reported distress, substantially increased heart rate (HR) and breathing rate (BR) were expected at the start of therapy and predicted to improve over time. Since physical exercise demands during therapy were low, any large HR or BR responses were considered part of the psychophysiological response. Methods : This study used pooled data collected during a randomized controlled trial of 3MDR, which demonstrated significant improvement as measured by the Clinician Administered PTSD Scale. Whilst attending therapy, HR and BR data, subjective units of distress (SUD) score and phrases to describe feelings whilst exposed to trauma-related images were collected continuously from 37 UK male military veterans with PTSD. Results : HR and BR were significantly increased throughout all sessions ( p < .01 for both). Whilst HR was raised slightly remaining on average below 100 beats/minute, BR was increased substantially with average values between 40 and 50 breaths/minute. SUD scores were very high during therapy which concurred with the many negative feelings experienced during therapy sessions. Across the course of the treatment, SUD scores ( p < .01) and negative feelings were reduced ( p < .001), and positive feelings have increased ( p < .01) significantly, reflecting improvements in clinicians assessed PTSD symptoms. Across therapy sessions, HR ( p = .888) and BR ( p = .466) responses did not change. Conclusions : The strong psychophysiological response alongside high levels of self-reported distress and negative feelings is interpreted as high emotional engagement during therapy. A novel finding was the very significant BR increase throughout recorded sessions. Future PTSD research should include BR response to therapy and explore breathing control as a treatment target.
