Hand function assessments are critical for upper limb rehabilitation, but are unable to accurately reflect performance in the individual’s home environment. Video from wearable cameras (egocentric video), paired with deep learning, can assess hand function during activities of daily living (ADLs) at home. Previous studies have focused on analyzing quantitative aspects of hand usage, but there has yet to be a study that uses deep neural networks to assess the quality of hand usage from egocentric video. To train a deep neural network to predict hand function assessment scores from egocentric video. The dataset used contained egocentric videos of ADLs performed by 17 participants with AIS grades from A-D in a home simulation laboratory. Tasks were annotated with scores adapted from the Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP). The annotated video was then used to train and validate a SlowFast neural network to predict GRASSP scores, using leave-one-subject-out cross validation. Model performance was evaluated by mean absolute error, accuracy, and F1 score. The model was optimized with a hyperparameter sweep. The top performing model demonstrated a mean absolute error of 0.52±0.19, an accuracy of 0.55±0.14, and F1 score of 0.55±0.16, on an ordinal scale from 1 to 5. These results demonstrate that automated assessment of hand function is possible by applying deep learning to egocentric video. Future work should expand the model to larger datasets with more variability.","PeriodicalId":46769,"journal":{"name":"Topics in Spinal Cord Injury Rehabilitation","volume":"15 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139344244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mainstream technology options, such as virtual reality (VR), have the potential to facilitate needed exercise participation. However, further research on VR exercise modalities is needed to determine feasibility, effectiveness and to ultimately guide practice recommendations. The goal of this pilot feasibility study was to determine whether VR exergaming is non-inferior to the current standard of care (SoC) upper extremity aerobic exercise for individuals with SCI/D. 25 participants with SCI/D completed 10-minute exercise sessions with either VR or the SoC, and after a rest break, then completed 10 minutes of exercise with the other modality. Primary outcomes of heart rate (HR) and rate of perceived exertion (RPE) were collected at baseline, 5 minutes into exercise, and at 10 min (end of the exercise session) for each modality. Secondary exploratory measures included a Numeric Pain Rating Scale measured pre- and post- each exercise session, and a post-study likeability survey. There were no significant differences in HR or RPE between virtual reality exergaming and the standard of care, and 100% of participants preferred the VR over SoC for the exercise. VR exergaming was non-inferior to the SoC for short duration upper extremity exercise in those with SCI/D. Implementing VR for patients with SCI/D should be studied further to observe the longer term effect on cardiovascular health and to determine feasibility and compliance for home use.","PeriodicalId":46769,"journal":{"name":"Topics in Spinal Cord Injury Rehabilitation","volume":"98 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139346193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Qualitative study based on Van Manen’s phenomenology using purposive sampling at the Spinal Injury Rehabilitation Center, the only dedicated SCI center in Nepal. We interviewed participants (n=24) who were referred from nine different acute hospitals using a semi-structured interview guide co-developed with SCI experts and PWSCI. Using thematic analysis, we extracted the findings with Manen’s approach. We identified three preliminary themes: (1) Families, but not PWSCI, are often included in the decision-making process; (2) For education on secondary complications, only pressure injury prevention was recalled; (3) Timeliness of spinal surgery was a concern. There are opportunities to improve the acute care experience for PWSCI in Nepal. PWSCI desired to be more engaged in the decision-making process and more involved in their own care.

Articles included in the review were evaluated for methodological quality and presented descriptively because of the heterogeneity in study design, populations and outcomes. Of the 6,031 unique citations originally identified, 14 articles were included after full-text screening. Two-third of the studies were for stroke and half of the studies originated from the US. Robot-assisted therapies represented half of the studies and about a quarter were locomotor training programs. In the stroke and spinal cord injured population, robot-assisted therapies and body supported treadmill therapy appear to be cost-effective respectively. There is some evidence to support the cost-effectiveness of robot-assisted therapies and body supported treadmill therapy.

The objectives of this study were to investigate: (1) TSS above and below a spinal cord injury (SCI) lesion results in different recruitment pattern of upper limb (UL) motor pools compared to neurologically intact subjects (NIS), and (2) the relationship between recruitment pattern of UL motor pools and neurological and functional status in individuals with SCI. Methods: Eleven NIS and six participants with cervical SCI were recruited in this study. We compared spinally evoked motor potentials in UL muscles during TSS delivered to the cervical spinal cord between the spinous process of C3-C4 and C7-T1 vertebrae. As expected, TSS delivered over the cervical spinal cord in NIS can preferentially activate proximal and distal muscles along the rostrocaudal axis, as well as ipsilateral UL muscles along the mediolateral axis. However, in participants with SCI, the responses registered in UL muscles innervated by motor pools above and below the lesion demonstrated different recruitment compared to NIS, and were dependent on the level, extent, and side of SCI. The spatial map obtained from assessing evoked potentials above and below the lesion contributes to the comprehensive understanding of the viability and function of specific UL motor pools, and can be utilized to monitor changes in recruitment patterns of the UL motor pools during neurorehabilitation interventions after SCI.","PeriodicalId":46769,"journal":{"name":"Topics in Spinal Cord Injury Rehabilitation","volume":"53 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139347084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Where applicable, study results will be presented using summary statistics. Work is currently underway to identify the citations. Two reviewers will then screen the titles and abstracts. It is anticipated that a large majority of the citations will be screened out with a small number of studies remaining.

Our objective was to investigate the moderating effect of in-person and online social supports on the association between relationship quality, caregiver competence, caregiver distress and caregiver burden. 115 caregivers who resided in Canada or the United States, understood and spoke English, and self-identified as primary family caregivers of an individual with SCI were sampled. Participants completed measures assessing relationship quality, competence, distress, burden, and in-person and online social support. Three separate moderation analyses for each outcome variable (i.e. relationship quality, competence, and distress), were conducted. In analyses, burden was the predictor, and online and in-person support were moderators. Moderation analyses showed that online support moderates the link between caregiver burden and distress. Slope analyses revealed that the positive relationship between burden and distress was weaker when caregivers reported lower levels of online support (p=0.005); this relationship was more robust when caregivers reported higher levels of online support (p <.001). Other moderation analyses were not statistically significant. Online support increases distress in family caregivers.
