OBJECTIVES
Social isolation and loneliness pose significant public health risks, especially among older adults experiencing age-related cognitive decline (ACD). This mixed methods feasibility study explored the potential of an online mindfulness-based dance/movement therapy (M-DMT) program to alleviate loneliness, enhance psychological well-being, and promote physical activity among older adults experiencing ACD during the COVID-19 pandemic.
METHOD
Sixteen participants engaged in a 12-week online group M-DMT program. Feasibility was assessed enrollment and retention rates, attendance, adverse events, credibility/expectancy, participant perceptions, and satisfaction. Qualitative data were collected to capture participants' perspectives on the intervention's usefulness and perceived benefits. The intervention's preliminary impact on loneliness, depression, positive affect, psychological well-being, and physical activity was also examined.
RESULTS
The study met all feasibility criteria, with 65% reporting post-intervention improvement. Significant reductions in loneliness and depression, along with enhanced positive affect and psychological well-being, were observed. Though physical activity increased, statistical significance was not achieved. Qualitative feedback highlighted improved social connectedness, overall quality of life, body awareness, kinematic strategy, and satisfaction with the program.
CONCLUSION
Online M-DMT holds promise in addressing well-being and loneliness challenges in older adults experiencing ACD. Further research is necessary to validate and expand upon these promising findings.

de Lemos Muller, CH, Farinha, JB, Leal-Menezes, R, and Ramis, TR. Aerobic training with blood flow restriction on muscle hypertrophy and strength: systematic review and meta-analysis. J Strength Cond Res 38(7): 1341-1349, 2024-Integrating strength and endurance training in a single exercise session, even on separate days, can be physically demanding and time-consuming. Therefore, there is a growing interest in identifying efficient training methods that can concurrently enhance cardiovascular and neuromuscular performance through a singular training modality. This study conducted a systematic review and meta-analysis to explore the effects of aerobic training with blood flow restriction (AT + BFR) on muscle hypertrophy and strength gains in healthy individuals. Our study was registered at PROSPERO and used multiple databases (PubMed, Embase, Scopus, and Web of Science), seeking clinical trials that examined AT + BFR influence on muscle hypertrophy and strength gains in individuals aged 18-60 years and comparing with aerobic training without BFR. The risk of bias and method quality were assessed using the ROB2.0 tool and PEDro scale, respectively, and the quality of evidence was evaluated with the GRADE method. A random-effects model was used for meta-analysis, and standardized mean difference (SMD) was calculated for each outcome. Of 4,462 records, 29 full texts were assessed for eligibility, with 7 articles meeting the inclusion criteria. The results indicated that AT + BFR was more beneficial for inducing muscle hypertrophy than aerobic training without BFR (SMD [95% CI] = 0.86 [0.37-1.35]; I2 = 42%). Furthermore, AT + BFR was associated with greater improvements in muscle strength (SMD [95% CI] = 0.41 [0.10-0.72]; I2 = 0%). Despite the generally high risk of bias for both outcomes, these encouraging findings underscore the clinical significance of AT + BFR as a compelling tool for enhancing neuromuscular parameters.

This study aimed to investigate posterior chain muscle function and the influence of shoes in ballet dancers with and without low back pain (LBP) in the . Twenty-nine young professional ballet dancers (17 with LBP and 12 healthy controls) were recruited. Muscle strength and mechanical properties of the erector spinae and hamstrings were assessed. The displacement of centre of mass (COM) during under different shoe conditions (R-class, Chacott, and own shoes) was measured with a motion capture system. The LBP group exhibited greater dynamic stiffness and decreased mechanical stress relaxation time in the lateral hamstring compared to the control group. During , the LBP group demonstrated significantly greater anterior-posterior displacement of the COM and a larger percentage of time to achieve maximal trunk extension angle. The COM displacement in vertical and medial-lateral directions was smaller in the R-class than in their own shoes. LBP impacts muscle mechanical properties, particularly in the lateral hamstring. The compromised muscle function resulted in a longer time to spinal extension during , signifying that reduced trunk control contributed to greater COM displacement. Hence, it is essential to emphasise that evaluating muscle properties and dynamic postural control is imperative for dancers experiencing LBP.

INTRODUCTION
There is growing research evidence on bodily discourses and body image issues of women with disabilities. Within the art-based intervention repertoire for persons with disabilities, dance and movement-based therapies and interventions are gaining prominence. The aim of this study was to examine the impact of dance sessions (delivered online) on body image, body satisfaction/dissatisfaction, and wellbeing of women with disabilities.
METHOD
A quasi-experimental waitlist control design study was conducted with data collected at two time points: baseline or pre-test and five-months later or post-test. Outcomes were measured using the Body Image Scale and the WHO-5-Wellbeing Index.
RESULTS
The dance sessions were effective (Hedges' g = -0.56 -0.88; p < 0.01) and post-test body dissatisfaction scores were lower and wellbeing scores were higher for participants with a college degree or postgraduate degree, self-employed or students, and whose intervention compliance was above threshold (>50% dance sessions attended and corresponding homework sessions completed). Tobit regression models indicated that it was possible to estimate post-test outcomes due to dance sessions alone, controlling for significant socio-demographics.
DISCUSSION
The domain knowledge of non-pharmacological art-based interventions for persons with disabilities, particularly women, is supported.
CONCLUSIONS
Findings commend dance sessions as effective psychotherapeutic mechanisms to mitigate body dissatisfaction, improve body image and wellbeing of women with disabilities. Future research may focus on large-scale cross-sectional trials, variations in the repertoire for women with different disability types and histories, and qualitative narratives.

Medicine Jun 2024To explore the effect of dance art on the treatment of hospitalized patients with chronic schizophrenia. (Randomized Controlled Trial)
Randomized Controlled Trial
BACKGROUND
To explore the effect of dance art on the treatment of hospitalized patients with chronic schizophrenia.
METHODS
In a prospective randomized controlled study conducted from June 2019 to June 2020, 120 patients from Shanghai Pudong New Area Mental Health Center were divided into intervention (n = 60) and control (n = 60) groups using a random number table. Control patients received standard drug treatment and nursing care, while the intervention group underwent dance art therapy sessions for 90 minutes twice weekly, in addition to standard care. Treatment outcomes after 6 and 12 weeks were measured using the positive and negative symptom scale (PANSS), Wisconsin Card Sorting Test (WCST), Montreal Cognitive Assessment Scale (MoCA), and body mass index (BMI).
RESULTS
This study involved 120 male patients with chronic schizophrenia, aged 30 to 60 years. After 6 and 12 weeks, the intervention group showed a greater reduction in PANSS scores (intervention group: from 49.02 ± 2.53 to 37.02 ± 1.83, control group: from 49.08 ± 2.59 to 44.91 ± 2.35, P < .05). In the WCST, the intervention group exhibited a higher increase in classification completion and correct answers, and a greater decrease in errors (P < .05). MoCA scores improved significantly in the intervention group compared to the control group (P < .05). BMI decreased in both groups, with a more pronounced reduction in the intervention group (intervention group: from 26.47 ± 1.05 kg/m² to 22.87 ± 0.73 kg/m², control group: from 26.50 ± 1.03 kg/m² to 26.22 ± 0.80 kg/m², P < .05).
CONCLUSION
Based on routine drug treatment and routine nursing care, dance art has a better clinical effect in treating hospitalized patients with chronic schizophrenia, which can improve cognitive function, alleviate clinical symptoms, and reduce BMI.

Review
INTRODUCTION
Contemporary concussion literature has yet to establish appropriate clinical management guidelines to address the unique needs of performing arts populations, especially at the collegiate level. Therefore, the purpose of this investigation was to collate current evidence regarding post-concussion return to performance management among university-aged performing artists to generate broad clinical implications.
METHODS
The research team was comprised of two faculty members in the performing arts, one concussion researcher, and athletic trainer, two university librarians, and one physical therapy graduate student with expertise in post-concussion management among performing arts patients. Two librarians searched the literature using PubMed, Cochrane, SPORTdiscus, and Education Research Complete. Studies were eligible for preliminary inclusion if they were written in English, conducted in the United States, as well as published in a peer-reviewed journal. There were no restrictions on publication date due to the limited literature on this topic. The most recent search was conducted in July 2023.
RESULTS
Of the 18 studies identified during the search process, only 2 met the inclusion criteria. Broadly, this investigation identified common mechanisms of injury among stage crew/technicians and dancers who are of university-age. Furthermore, both studies identified several patients who opted to return to performing arts on their own volition. However, there were no studies that solely focused on the collegiate performing arts population and their return to performance procedures.
CONCLUSIONS
Overall, these findings highlight a momentous gap in concussion literature regarding how to guide clinicians and academic teams when returning collegiate performing artists back to their performance environment(s). Thus, additional research is strongly warranted to understand the lived experiences of performing artists with concussion, as well as how to address specific coursework-related demands to support their recovery.

INTRODUCTION
Dance Medicine is a growing discipline, and healthcare for dancers requires appreciating particularities of their artistic craft. Manual therapists (MTs) are often dancers' first choice when seeking care. Whilst dancers' experiences of injury and healthcare have been extensively researched, little is known of MTs' perspectives of caring for them.
AIM
This study aimed to gain an understanding of MTs' perspectives of caring for dancers. Communication, treatment strategies and obstacles to a successful therapeutic alliance were examined to broaden knowledge and improve care.
METHODS
This was a qualitative study using Grounded Theory as a framework for data collection and analysis. A purposive sample of 8 participants was recruited-physiotherapists, chiropractors, and osteopaths with 2+ years' experience of treating dancers. Data collection was conducted via semi-structured interviews, which were transcribed verbatim, anonymized, member checked, and later analyzed.
RESULTS
Data analysis constructed 3 categories which described the range of participants' experiences. Two categories were identified-(i) and (ii) and found to culminate in a core category: (iii) , which exemplified MTs' attempts to address clinical challenges.
CONCLUSIONS
MTs experience several challenges when providing healthcare to dancers. These encompass psychosocial aspects relating to dancers' internal world and the dance industry environment. It suggests that caring for dancers demands comprehensive, collaborative, and psychologically informed approaches. Emphasis should also be given to developing and implementing dance-specific pain science for all stakeholders.

Effect of muscle length on maximum evoked torque, discomfort, contraction fatigue, and strength adaptations during electrical stimulation in adult populations: A systematic review.
Neuromuscular electrical stimulation (NMES) can improve physical function in different populations. NMES-related outcomes may be influenced by muscle length (i.e., joint angle), a modulator of the force generation capacity of muscle fibers. Nevertheless, to date, there is no comprehensive synthesis of the available scientific evidence regarding the optimal joint angle for maximizing the effectiveness of NMES. We performed a systematic review to investigate the effect of muscle length on NMES-induced torque, discomfort, contraction fatigue, and strength training adaptations in healthy and clinical adult populations (PROSPERO: CRD42022332965). We conducted searches across seven electronic databases: PUBMED, Web of Science, EMBASE, PEDro, BIREME, SCIELO, and Cochrane, over the period from June 2022 to October 2023, without restricting the publication year. We included cross-sectional and longitudinal studies that used NMES as an intervention or assessment tool for comparing muscle lengths in adult populations. We excluded studies on vocalization, respiratory, or pelvic floor muscles. Data extraction was performed via a standardized form to gather information on participants, interventions, and outcomes. Risk of bias was assessed using the Revised Cochrane risk-of-bias tool for cross-over trials and the Physiotherapy Evidence Database scale. Out of the 1185 articles retrieved through our search strategy, we included 36 studies in our analysis, that included 448 healthy young participants (age: 19-40 years) in order to investigate maximum evoked torque (n = 268), contraction fatigability (n = 87), discomfort (n = 82), and muscle strengthening (n = 22), as well as six participants with spinal cord injuries, and 15 healthy older participants. Meta-analyses were possible for comparing maximal evoked torque according to quadriceps muscle length through knee joint angle. At optimal muscle length 50° - 70° of knee flexion, where 0° is full extension), there was greater evoked torque during nerve stimulation compared to very short (0 - 30°) (p<0.001, CI 95%: -2.03, -1.15 for muscle belly stimulation, and -3.54, -1.16 for femoral nerve stimulation), short (31° - 49°) (p = 0.007, CI 95%: -1.58, -0.25), and long (71° - 90°) (p<0.001, CI 95%: 0.29, 1.02) muscle lengths. At long muscle lengths, NMES evoked greater torque than very short (p<0.001, CI 95%: -2.50, -0.67) and short (p = 0.04, CI 95%: -2.22, -0.06) lengths. The shortest quadriceps length generated the highest perceived discomfort for a given current amplitude. The amount of contraction fatigability was greater when muscle length allowed greater torque generation in the pre-fatigue condition. Strength gains were greater for a protocol at the optimal muscle length than for short muscle length. The quality of evidence was very high for most comparisons for evoked torque. However, further studies are necessary to achieve certainty for the other outcomes. Optimal muscle length should be considered the primary choice during NMES interventions, as it promotes higher levels of force production and may facilitate the preservation/gain in muscle force and mass, with reduced discomfort. However, a longer than optimal muscle length may also be used, due to possible muscle lengthening at high evoked tension. Thorough understanding of these physiological principles is imperative for the appropriate prescription of NMES for healthy and clinical populations.

Patient Attitudes Toward Self- or Partner-, Friend-, or Family-Administered Long-acting Injectable Antiretroviral Therapy: A Mixed-Methods Study Across 3 Urban Human Immunodeficiency Virus Clinics.
BACKGROUND
Long-acting injectable (LAI) cabotegravir/rilpivirine (CAB/RPV) offers a novel drug delivery option for persons with human immunodeficiency virus (PWH) but requires administration every 4 or 8 weeks by a medical professional.
METHODS
To facilitate LAI antiretroviral therapy (ART) scale-up, we evaluated patient interest in alternative administration approaches via a mixed-methods, serial cross-sectional study across 3 US HIV clinics. We surveyed PWH (December 2021 to May 2022) on appeal of self- or partner/friend/family-administered LAI-CAB/RPV; multivariable ordinal logistic regression explored associated characteristics. To contextualize survey results, we thematically analyzed semi-structured interview data collected from PWH (August 2020 to July 2021) on attitudes toward out-of-clinic LAI-ART administration.
RESULTS
Among 370 surveyed PWH (median age, 46 years; 26% cisgender female, 59% Black, 56% sexual minority, 34% housing instability), self-administering LAI-CAB/RPV appealed to 67%. PWH who were White (adjusted odds ratio [aOR], 3.30 [95% confidence interval {CI}, 1.42-7.64]), stably housed (aOR, 2.16 [95% CI, 1.30-3.59]), or gay/bisexual (aOR, 1.81 [1.14-2.89]) were more likely to endorse self-administration. Fewer PWH (60%) reported partner/friend/family administration as appealing; adjusted models revealed similar sociodemographic preferences for this outcome. In 72 interviews, PWH noted that acceptability of out-of-clinic LAI-ART administration was qualified by convenience, prior injection experience, and potential fear of self-inflicted pain, dependence on others, and/or HIV disclosure.
CONCLUSIONS
In a multisite sample of PWH, self- and, to a lesser extent, partner/friend/family-administration of LAI-CAB/RPV appealed to most; however, was less appealing among populations more impacted by health disparities. Innovative LAI-ART delivery options could free up in-clinic resources to focus scale-up among marginalized populations.
