“…45 In our study, the researcher educated the participants’ caregivers on the anatomical reference point using high-resolution images shared via the “screen sharing” function in the telePTsys software, providing real-time guidance while placing the coloured adhesive markers on the anatomical reference points, and employed the photogrammetry method for posture assessment. 46 With these measures, our current study shows high concurrent validity in TR-based neck posture assessment, even with the low-resolution (320 × 240) images.…”

Introduction The aim of this study was to determine the concurrent validity and reliability of telerehabilitation (TR)-based evaluation of the cervical spine among adults with non-specific neck pain (NS-NP). Methods A total of 11 participants with NS-NP were recruited. Pain intensity, active range of motion (AROM), posture, deep neck flexor (DNF) endurance, combined neck movements and disability were measured using face-to-face and TR methods, with a one-hour break in between. TelePTsys, an image-based TR system, was used for TR assessment. Results A high degree of concurrent validity for pain (bias = 0.90), posture (bias = 0.96°), endurance (bias = –2.3 seconds), disability (bias = 0.10), AROM (extension bias = –0.60 cm, flexion bias = 1.2 cm, side flexion bias = –1.00, rotation bias = –0.30 cm) was found. Standard error of measurement and coefficient of variation (CV) values were within the acceptable level for concurrent validity, except the CV for cervical flexion and endurance. There was a high degree of reliability demonstrated for pain, posture, AROM, endurance and disability measurements. The average-measure interclass correlation coefficient (ICC(3,1)) ranged from 0.96 to 0.99 for inter-rater, and 0.93 to 0.99 for intra-rater reliabilities. There was moderate agreement for combination movement for validity (78.5%, p < 0.05), inter- (78.5%, p < 0.05) and intra-rater (76.4%, p < 0.05) reliabilities. Discussion TR-based physiotherapy assessment of cervical spine is a valid and reliable tool for measuring pain intensity, AROM, DNF muscle endurance, sagittal neck posture and disability among adults with NS-NP via telePTsys.

“…As raw data is rarely provided in published works, we developed a protocol for extracting data accurately and precisely. WebPlotDigitizer is a freely available graphical analysis program that allowed for quick and reliable extraction of data from plots and figures (Drevon et al, 2017; Mani et al, 2018; Rohatgi, 2017). For variables where data were not graphically represented, data points were generated in MATLAB using the mean and standard deviation reported in the original source paper (Karantanis et al, 2017a, 2017b, 2017c; Granatosky, Schmitt, et al, 2019).…”

Gait mechanics of a blind echolocating rodent: Implications for the locomotion of small arboreal mammals and proto‐bats

et al. 2021

Arboreal mammals have evolved a range of biomechanical adaptations that allow them to navigate trees effectively. One such feature that has received considerable attention is the importance of vision that helps arboreal animals assess gap distances, assure proper foot placement, and inspect potential risks. While there is considerable debate about the relative importance of the visual system specifics, there is little doubt that the ability to at least see the environment must confer some level of safety when navigating arboreal substrates. In this study, we explore spatiotemporal and kinematic patterns of arboreal locomotion in the Vietnamese pygmy dormouse (Typhlomys chapensis), a blind rodent that uses ultrasonic echolocation to navigate in tree canopies. We compare these data with five other species of arboreal rodents and primates. Spatiotemporal gait characteristics are largely similar between the Vietnamese pygmy dormouse and other small‐bodied arboreal species analyzed. Most notable is the tendency for relatively high‐speed asymmetrical gaits on large‐diameter substrates and slower symmetrical lateral‐sequence gaits on small‐diameter substrates. Furthermore, for all species speed is primarily regulated by increasing stride frequency rather than length. Kinematics of the Vietnamese pygmy dormouse changed little in response substrate size and were primarily driven by speed. These findings suggest that the information gathered during ultrasonic scanning is sufficient to allow effective quadrupedal locomotion while moving on arboreal supports. The Vietnamese pygmy dormouse may serve as a model for the quadrupedal nocturnal ancestor of bats, which had started developing ultrasonic echolocation and reducing vision while likely occupying an arboreal niche.

“…We independently extracted the data from Figures 1 and 2 (pgs. 351-352; 15 participants total) of the source study using WebPlotDigitizer (Mani, Sharma, & Singh, 2018). WebPlot-Digitizer has been shown to result in high levels of reliability and validity for extracting single case design data (Drevon, Fursa, & Malcolm, 2017).…”

Behavior analysis and statistical inference have shared a conflicted relationship for over fifty years. However, a significant portion of this conflict is directed toward statistical tests (e.g., t‐tests, ANOVA) that aggregate group and/or temporal variability into means and standard deviations and as a result remove much of the data important to behavior analysts. Mixed‐effects modeling, a more recently developed statistical test, addresses many of the limitations of more basic tests by incorporating random effects. Random effects quantify individual subject variability without eliminating it from the model, hence producing a model that can predict both group and individual behavior. We present the results of a generalized linear mixed‐effects model applied to single‐subject data taken from Ackerlund Brandt, Dozier, Juanico, Laudont, & Mick, 2015, in which children chose from one of three reinforcers for completing a task. Results of the mixed‐effects modeling are consistent with visual analyses and importantly provide a statistical framework to predict individual behavior without requiring aggregation. We conclude by discussing the implications of these results and provide recommendations for further integration of mixed‐effects models in the analyses of single‐subject designs.
