RESUMO
Functional neurological disorder (FND) is a heterogeneous condition of neurological symptoms that cannot be linked to a specific neurological cause. Yoga combines movement, breathing, and meditation and has established mind-body effects for people who are managing both psychological and neurological conditions. This case series describes key components of a yoga program for people with FND, evaluating feasibility, acceptability, and efficacy via self-report surveys, clinical assessments, and postintervention interview. Four individuals with FND participated in 45-minute, one-to-one virtual yoga sessions, two times a week for 8 weeks. We measured outcomes in four domains (healthcare utilization, FND symptoms, quality of life and self-efficacy, and function and mobility) at baseline, week 4, and week 8. Assessments included the Psychogenic Movement Disorders Rating Scale, timed up-and-go test, Patient Health Questionnaire-15, Brief Illness Perceptions Questionnaire, 36-Item Short Form Health Survey, and University of Washington Self-Efficacy Scale. Four participants completed at least 8 sessions, and two completed the full intervention (16 sessions). There were no adverse events. Two participants reported positive changes after yoga and improved on all clinical assessments (timed up-and-go test and Psychogenic Movement Disorders Rating Scale). Postintervention interview analysis revealed three themes: negative diagnosis experience, perceived health effects of yoga, and session format preferences. This was an exploratory case series describing a yoga intervention that was associated with some benefits for people with FND (decreased FND symptom severity and increased function, perceived health, quality of life, and self-efficacy). A larger case series is warranted to understand how to best select individuals who would benefit from the program.

Aim: To evaluate the feasibility of using activity monitors in a physical activity (PA) intervention in people with Parkinson's (PD) and Huntington's disease (HD). Materials & methods: People with early-stage PD (n = 13) and HD (n = 14) enrolled in a 4-month coaching program, wore a Fitbit, and were guided through a behavioral intervention to facilitate PA uptake. Wear time, wear habits and activity metrics (e.g., steps) were analyzed. Results: Retention rate was 85% and participants had an average 92.3% (±9.2) valid wear days. Daily wear time was 18.4 (±4.5) h. Day & night Fitbit wearers showed improvements in steps (d = 1.02) and MET×min/week (d = 0.69) compared with day-only wearers. Conclusion: Implementing wearables in a coaching intervention was feasible and provided insights into PA behavior.

We established wastewater surveillance of SARS-CoV-2 in a small, residential, urban college as part of an integrated public health response during the COVID-19 pandemic. Students returned to campus in spring 2021. During the semester, students were required to perform nasal PCR tests twice weekly. At the same time, wastewater monitoring was established in 3 campus dormitory buildings. Two were dedicated dormitories with populations of 188 and 138 students; 1 was an isolation building where students were moved within 2 h of receiving positive test results. Analysis of wastewater from isolation indicated that the amount of viral shedding was highly variable and that viral concentration could not be used to estimate the number of cases at the building level. However, rapid movement of students to isolation enabled determination of predictive power, specificity, and sensitivity from instances in which generally one positive case at a time occurred in a building. Our assay yields effective results with an ~60% positive predictive power, ~90% negative predictive power, and ~90% specificity. Sensitivity, however, is low at ~40%. Detection is improved in the few instances of 2 simultaneous positive cases, with sensitivity of 1 case versus 2 cases increasing from ~20% to 100%. We also measured the appearance of a variant of concern on campus and noted a similarity in timeline with increased prevalence in surrounding New York City. Monitoring SARS-CoV-2 in the sewage outflow of individual buildings can be used with a realistic goal of containing outbreak clusters but not necessarily single cases. IMPORTANCE Diagnostic testing of sewage can detect levels of circulating viruses to help inform public health. Wastewater-based epidemiology has been particularly active during the COVID-19 pandemic to measure the prevalence of SARS-CoV-2. Understanding the technical limitations of diagnostic testing for individual buildings would help inform future surveillance programs. We report our diagnostic and clinical data monitoring of buildings on a college campus in New York City during the spring 2021 semester. Frequent nasal testing, mitigation measures, and public health protocols provided a context in which to study the effectiveness of wastewater-based epidemiology. Our efforts could not consistently detect individual positive COVID-19 cases, but sensitivity is significantly improved in detecting two simultaneous cases. We therefore contend that wastewater surveillance may be more practically suited for the mitigation of outbreak clusters.
RESUMO
BACKGROUND: There is a growing body of literature assessing the potential benefits of dance for individuals post-stroke. OBJECTIVES: We conducted a scoping review mapping the state of the literature on feasibility, intervention procedures, and efficacy of dance to improve health-related outcomes for individuals post-stroke. ELIGIBILITY CRITERIA: Included studies were original research that described the use of a dance intervention for individuals post-stroke, included any health-related outcome, and were written in English. SOURCES OF EVIDENCE: Databases selected were Pubmed, Scopus, Google Scholar, Proquest, MedRxiv, and CINHAL. CHARTING METHODS: Two reviewers extracted relevant data and results were organized into themes and categories determined by all authors through discussion. RESULTS: We searched electronic databases were in February 2021. We included 18 publications from 14 studies. Ten were quantitative, five were qualitative, one was mixed-methods, and two were community project descriptions. Twelve publications evaluated in-person dance classes and six evaluated dance exergaming. Based on the limited studies included, evidence suggests dance is a feasible and potentially effective intervention for individuals post-stroke. Studies demonstrate dance may facilitate changes in balance and fall risk, encourage confidence, promote comfort with the changed body, increase rehabilitation motivation, and facilitate community reintegration. Evidence is limited by number of studies, design (lack of control groups and blinded assessments), intervention descriptions, and outcomes reporting. CONCLUSIONS: There is growing interest in dance for stroke interventions. Further research should focus on rigorous study design, optimal intervention timing, consistency of reporting outcomes, key elements of dance classes, and the impact of cultural dance styles.

BACKGROUND: Parkinson disease (PD) is a neurodegenerative disease that has a wide range of motor symptoms, such as tremor. Tremors are involuntary movements that occur in rhythmic oscillations and are typically categorized into rest tremor or action tremor. Action tremor occurs during voluntary movements and is a debilitating symptom of PD. As noninvasive interventions are limited, there is an ever-increasing need for an effective intervention for individuals experiencing action tremors. The Microsoft Emma Watch, a wristband with 5 vibrating motors, is a noninvasive, nonpharmaceutical intervention for tremor attenuation. OBJECTIVE: This pilot study investigated the use of the Emma Watch device to attenuate action tremor in people with PD. METHODS: The sample included 9 people with PD who were assessed on handwriting and hand function tasks performed on a digitized tablet. Tasks included drawing horizontal or vertical lines, tracing a star, spiral, writing "elelelel" in cursive, and printing a standardized sentence. Each task was completed 3 times with the Emma Watch programmed at different vibration intensities, which were counterbalanced: high intensity, low intensity (sham), and no vibration. Digital analysis from the tablet captured kinematic, dynamic, and spatial attributes of drawing and writing samples to calculate mathematical indices that quantify upper limb motor function. APDM Opal sensors (APDM Wearable Technologies) placed on both wrists were used to calculate metrics of acceleration and jerk. A questionnaire was provided to each participant after using the Emma Watch to gain a better understanding of their perspectives of using the device. In addition, drawings were compared to determine whether there were any visual differences between intensities. RESULTS: In total, 9 people with PD were tested: 4 males and 5 females with a mean age of 67 (SD 9.4) years. There were no differences between conditions in the outcomes of interest measured with the tablet (duration, mean velocity, number of peaks, pause time, and number of pauses). Visual differences were observed within a small subset of participants, some of whom reported perceived improvement. The majority of participants (8/9) reported the Emma Watch was comfortable, and no problems with the device were reported. CONCLUSIONS: There were visually depicted and subjectively reported improvements in handwriting for a small subset of individuals. This pilot study was limited by a small sample size, and this should be taken into consideration with the interpretation of the quantitative results. Combining vibratory devices, such as the Emma Watch, with task specific training, or personalizing the frequency to one's individual tremor may be important steps to consider when evaluating the effect of vibratory devices on hand function or writing ability in future studies. While the Emma Watch may help attenuate action tremor, its efficacy in improving fine motor or handwriting skills as a stand-alone tool remains to be demonstrated.
