Postural Control, Dual Task Performance and Executive Function Following an Ultramarathon

As research into the postural and cognitive effects of ultramarathon running is sparse and still needed, we investigated the effect of ultramarathon running on runners’ postural control, dual task postural control and a measure of executive function—the flanker test, expecting fatigue-related deterioration on each measure. We used a pre- and post-test research design with 14 runners who completed (a) postural assessment with eyes open and closed, on a flat surface and on foam during (b) a two-choice reaction time dual task postural assessment, and (c) an executive function modified flanker task. With regard to postural stability, we observed, after running, increased anterior-posterior (AP) path length and AP root mean square (RMS) and reductions in both mediolateral (ML) RMS and ML median frequency. Dual task analysis showed reduced ML RMS prior to the race, whereas the effect was absent afterwards. Reaction times were not significantly altered between pre-post or surface conditions assessments. There were no statistically significant differences in mean modified flanker scores before and after the race. These data demonstrated that, following an endurance run, there were plane specific movement adaptations in postural sway that may have resulted from neuroprotective changes under extreme fatigue.

Development and evaluation of an Agricultural Cumulative Risk Evaluation System (ACRES): An ergonomic tool usability study across various lifting and postural assessment systems for novice users

This paper aims to compare agreeance of four of most commonly used ergonomics assessment tools as well as introduce the Agriculture Cumulative Risk Evaluation Systems (ACRES), a tool that assesses both lifting and posture. ACRES discretizes factors to evaluate ergonomic risk. Participants lacked substantial experience with ergonomic tools, but were given instruction guides for each tool and tasked with evaluating various lifting and repetitive tasks to help evaluate initial perceptions. Results showed that REBA, QEC, and ACRES all had significant correlations with a more linear relationship between REBA and ACRES than REBA and QEC. The NIOSH lifting equation and the Snook and Cirello tables were too different to have significant correlation whereas ACRES was able to correlate with RNLE. In all cases REBA and the RNLE were found to be more difficult to use to novices and ACRES was perceived to be more appropriate for the lifting tasks.

Instrumental assessment of physiotherapy and onabolulinumtoxin-A on cervical and headache parameters in chronic migraine

Introduction The purpose of the present study is to compare the effect of the physiotherapy to onabolulinumtoxin-A, and their combination, in relation to cervical and headache parameters in patients with chronic migraine. Methods This is an observational cohort study conducted by a headache center and a physiotherapy degree course on 30 patients with chronic migraine. The patients were distributed in three groups of treatments for three months: onabolulinumtoxin-A only, physiotherapy only, and onabolulinumtoxin-A plus physiotherapy. The patients were evaluated, before and after each treatment, using the following: the postural assessment software SAPO for the forward head posture; the CROM goniometer for the cervical range of motion; the Migraine Disability Assessment Score for headache parameters. Results After 3 months of each treatment, the scores obtained for the headache-related disability and the frequency of migraine decreased significantly for all groups, but the pain intensity scores changed significantly only in the onabolulinumtoxin-A (p = 0.01) and in the onabolulinumtoxin-A plus physiotherapy groups (p = 0.007). On the other hand, the forward head posture was reduced significantly in the physiotherapy (p = 0.002) and in the onabolulinumtoxin-A plus physiotherapy groups (p = 0.003). The cervical range of motion increased significantly in certain directions in the physiotherapy group and in the onabolulinumtoxin-A plus physiotherapy groups. Conclusions The physiotherapy improved the cervical parameters. The onabolulinumtoxin-A decreased pain intensity. As a consequence, it can be said that the combined treatment was more useful than a mono-therapy alone. From our results, it can be concluded that onabolulinumtoxin-A plus physiotherapy could be a good option in the management of chronic migraine.

Prevalence of Scapular Dyskinesis in Breastfeeding Postnatal Women in Satara District - An Observational Study

BACKGROUND Poor posture like hunching forward is one of the most commonly practiced postures by women during breastfeeding. The maintenance of such postures for prolonged period can result in progressive weakness of the scapular muscles and subsequent increase in the kyphotic curve. Both lordosis and kyphosis increase during pregnancy and are observed to be maintained for up to 2 months postnatally. The thoracic spine position and slouched position significantly affects the scapular dynamics during scapular abduction resulting in decreased muscle forces. Thus, scapular dyskinesis, defined as an alteration of normal position or motion of the scapula during coupled scapulohumeral movements can occur as a result of decreased muscle forces. Thus, this gives rise to the need for evaluating scapular dyskinesis and its prevalence in postnatal women. The purpose of the study was to find the prevalence of scapular dyskinesis in breastfeeding postnatal women. METHODS An observational analytical study was undertaken at Krishna Institute of Medical Sciences, including a total of 40 subjects within the age group of (15 - 40) yrs. who had been breastfeeding for 6 months or more. These subjects were assessed for scapular dyskinesis using Yes / No test and the lateral scapular slide test (LSST). Kyphosis was assessed on observational basis through postural assessment in these individuals. Statistical analysis was done using the InStat app. RESULTS 67 % and 75 % of the subjects were found to be positive for scapular dyskinesis through Yes / No Test and LSST test respectively. Observational assessment showed that 55 % of the subjects were positive for kyphosis. Subjects demonstrated significant prevalence of scapular dyskinesis and subsequent kyphosis in postnatal females due to wrong ergonomic practice of breastfeeding. CONCLUSIONS The study shows that women lack proper knowledge about the breastfeeding ergonomics leading to weakness of scapular muscles. Thus, a significant prevalence of scapular dyskinesis was seen in breastfeeding postnatal women. KEY WORDS Breastfeeding, Scapular Muscle Weakness, Kyphosis, Ergonomics, Scapular Dyskinesis

Validation of an Ergonomic Assessment Tool for Dental Hygienists

Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations. Although multiple robust ergonomics tools are available to assess postural risk, these tools are often too general and do not consider nuances of specific jobs. This study examined the concurrent validity of a postural assessment tool tailored to dental professionals. Findings provide support for use of this tool to assess risk and identify areas for intervention by OT practitioners.

Impacts of Stroke on Muscle Perceptions and Relationships with the Motor and Functional Performance of the Lower Extremities

Stroke results in paretic limb disabilities, but few studies have investigated the impacts of stroke on muscle perception deficits in multiaxis movements and related functional changes. Therefore, this study aimed to investigate stroke-related changes in muscle perceptions using a multiaxis ankle haptic interface and analyze their relationships with various functions. Sixteen stroke patients and 22 healthy participants performed active reproduction tests in multiaxis movements involving the tibialis anterior (TA), extensor digitorum longus (EDL), peroneus longus, and flexor digitorum longus (FDL) of the ankle joint. The direction error (DE), absolute error (AE), and variable error (VE) were calculated. The lower extremity of Fugl-Meyer Assessment (FMA-LE), Barthel Index (BI), Postural Assessment Scale for Stroke Patients, Tinetti Performance-Oriented Mobility Assessment (POMA), and 10-m walk test (10MWT) were evaluated. VE of EDL for the paretic ankle was significantly lower than that for the nonparetic ankle (p = 0.009). AE of TA, EDL, and FDL and VE of EDL and FDL of muscle perceptions were significantly lower in healthy participants than in stroke patients (p < 0.05 for both). DE of TA for the paretic ankle was moderately correlated with FMA-LE (r = −0.509) and POMA (r = −0.619) scores. AE and VE of EDL for the paretic ankle were moderately correlated with the 10MWT score (r = 0.515 vs. 0.557). AE of FDL for the paretic ankle was also moderately correlated with BI (r = −0.562). This study indicated poorer accuracy and consistency in muscle perception for paretic ankles, which correlated with lower limb functions of stroke patients.

Spatio-Temporal Pyramid Graph Convolutions for Human Action Recognition and Postural Assessment

Recognition of human actions and associated interactions with objects and the environment is animportant problem in computer vision due to its potential applications in a variety of domains. Themost versatile methods can generalize to various environments and deal with cluttered backgrounds,occlusions, and viewpoint variations. Among them, methods based on graph convolutionalnetworks that extract features from the skeleton have demonstrated promising performance. In thispaper, we propose a novel Spatio-Temporal Pyramid Graph Convolutional Network (ST-PGN) foronline action recognition for ergonomic risk assessment that enables the use of features from alllevels of the skeleton feature hierarchy.
