Using theory knitting to conceptualize social phenomena in the design and evaluation of dance programs for people living with Parkinson's disease.

Dance programs for people living with Parkinson's disease (PwPD) offer participants an opportunity to exercise, engage in artistic self-expression, and form new relationships. While it is understood that the social dimension of dance programs for PwPD contributes to dancer satisfaction and program sustainability, the social mechanisms instrumental to program success are under-examined. Engaging with theory from wider disciplines, or "theory knitting" can help program designers and evaluators examine the mechanisms and contextual factors that make classes socially meaningful with greater detail and specificity. This study identified and examined three theoretical frameworks that program planners and evaluators could use to conceptualize social engagement in dance for PwPD contexts and inform practice. Each theory was assessed for fit using the T-CaST theory comparison and selection tool developed by Birken et al. (2018). As an example, we used anthropologist Victor Turner's (1970; 1977) theory of liminality and communitas to identify five key areas for fostering a sense of social connection in dance for PwPD contexts: (1) selecting a meaningful dance space (2) creating a joyous atmosphere (3) marking entrance into the liminal time and space with rituals (4) embodying liminality and anti-structure and (5) inverting power relations and embracing fluid roles.

Embodied collaborative writing in graduate dance education.

This paper explores how embodied writing can inform teaching, learning, and research presentation in graduate-level dance education in a kinesiology faculty. The focus is on a graduate dance course "The Dancing Body in Motion", which combines the anatomical analysis of the physical body, social theory, and lived dance experiences to promote more embodied and holistic teaching and learning. The authors, an instructor and a student of the course, share their experiences and reflections on the course through an embodied presentation of a dialogue that combines the instructor's lecture notes, the student's learning journal entries, and their reflections both separately and in conversation with each other. Their reflections offer insights into how the body and mind, material and social body, and practice and theory can all be brought together using embodied writing practices, such as a learning journal and performance ethnography, in a dance performance.

Target analysis of psychoactive drugs in oral fluid by QuEChERS extraction and LC-MS/MS.

This study aimed to validate a modified QuEChERS method, followed by liquid chromatography-tandem mass spectrometry, for the determination of 51 psychoactive substances and screening of 22 ones in oral fluid from electronic dance music party (EDM) attendees. Unstimulated oral fluid was collected in a polypropylene tube and stored in a glass vial at -20 ºC. The sample was extracted with acetonitrile:water and MgSO4/NaOAc, followed by cleanup with primary secondary amine and MgSO4. The effectiveness of the sample storage conditions was shown to be comparable to when the Quantisal™ buffer was used, with no substantial concentration loss (< 15%) for all the substances after up to 72 hours at -20º C. The method was satisfactorily validated, with limits of detection (LOD) and quantification (LOQ) ranging from 0.04 to 0.5 ng/mL and 0.1-1.5 ng/mL, respectively, and was applied to the analysis of 62 real samples. The main substances detected were 3,4-methylenedioxymethamphetamine (MDMA) (<0.5-829 ng/mL) and/or methylenedioxyamphetamine (MDA) (10.1 - 460.6 ng/mL), found in 27 samples, and cocaine (13.0-407.3 ng/mL) and its metabolites (benzoylecgonine 0.17-214.1 ng/mL; ecgonine methyl ester 1.8-150.1 ng/mL) in eight samples. Methamphetamine (11-439 ng/mL) was detected in eight samples, along with MDMA and MDA; eutylone was detected in two cases (4.7 and 24.1 ng/mL) reported as "ecstasy" ingestion. A comparison between self-reported drug use and results of oral fluid analysis indicated that the use of illicit substances is often underreported among EDM attendees, who are often unaware of the substances they consume.

Study on the effect of blood flow restriction training combined with IASTAM on ankle strength and function intervention in athletes with chronic ankle instability in sport dance events.

BACKGROUND: Athletes engaged in sports dance frequently encounter the potential for ankle injuries and instability, factors that may contribute to diminished training efficacy, compromised athletic performance, prolonged recuperation, and heightened susceptibility to recurring injuries. OBJECTIVE: The objective of this study was to investigate the impact of an exercise intervention (comprising blood flow restriction training combined with low-load ankle muscle strength training and balance training) as well as instrument-assisted soft tissue mobilization (IASTM) on the foot and ankle function, strength, and range of motion in sports dance athletes exhibiting ankle instability (CAI). METHODS: Thirty participants exhibiting ankle instability, restriction, or discomfort were recruited and randomly assigned to two groups: the Test group (comprising blood flow restriction training combined with IASTM, n = 15) and the traditional ankle strength training group (n = 15). The intervention spanned 4 weeks, with one session per week. Assessment of the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM), and ankle range of motion occurred at three time points: pre-intervention, immediately following the initial intervention, and after 4 weeks of intervention. Ankle strength testing was conducted solely before and after the intervention for comparative analysis. RESULTS: There were no significant variances in baseline characteristics between the two intervention groups. In terms of CAIT scores, both groups exhibited notably higher scores following the initial intervention and after 4 weeks of intervention compared to pre-intervention (P < 0.05). The Test group displayed higher CAIT scores than the control group, signifying a more pronounced enhancement in ankle stability among patients in the Test group. Concerning FAAM scores, both groups significantly enhanced ankle function in CAI patients (P < 0.05), with the Test group demonstrating notably higher FAAM-SPORT scores than the control group (P < 0.05), indicating superior restoration of athletic capability in the Test group. As for improvements in ankle range of motion, both groups demonstrated significant enhancements compared to pre-intervention (P < 0.05). The Test group exhibited significantly superior improvements in dorsiflexion, eversion, and inversion range of motion compared to the control group (P < 0.05), while the control group did not exhibit significant enhancements in plantarflexion and eversion range of motion (P > 0.05). Both groups displayed enhanced ankle strength in CAI patients following the intervention (P < 0.05), with the Test group manifesting notably higher dorsiflexion and inversion strength than the control group (P < 0.05). CONCLUSION: Both blood flow restriction training combined with IASTM and traditional ankle strength and stability training have shown significant improvements in stability, function, strength, and range of motion in CAI patients. Furthermore, the Test group exhibits superior efficacy in ankle stability, daily functional movement, dorsiflexion, and eversion range of motion compared to the control group. CLINICAL TRIAL REGISTRATION: 9 February 2024, ClinicalTrials.gov, ID; NCT06251414.

A study on the impact of systematic desensitization training on competitive anxiety among Latin dance athletes.

Objective: In the domain of competitive events, Latin dance athletes have always suffered competitive anxiety, which is a prevalent and prevailing psychological facet, in pre-, intra-, and post-competitive engagements. Usually, the implementation of systematic desensitization training is an efficacious approach to reduce competitive anxiety levels in routine sports to fortify psychological resilience of athletes (like swimming, volleyball, and basketball). This study focuses on the effect of systematic desensitization training on competition anxiety in the training of Latin dancers to establish good mental ability and promote the competitive ability of athletes. Methodology: The "Sports Competition Anxiety Test Questionnaire" was used to evaluate and classify the competitive anxiety levels of 150 Latin dance athletes. Then, the top 48 participants were selected (24 in the intervention cohort and 24 in the non-intervention cohort) as the study participants after stratifying anxiety score levels from the highest to the lowest. The intervention group was treated with an 8-week psychological intervention by employing systematic desensitization training techniques (encompassing imagery desensitization and in vivo desensitization). The anxiety levels of the subjects were quantified by employing the "Sport Competition Trait Anxiety Inventory" (CCTAI-C) and the "Competitive State Anxiety Inventory" (CSAI-2) to scrutinize the efficacy of systematic desensitization training in regulating competitive anxiety levels among Latin dance athletes. Results: After applying systematic desensitization training, the intervention group displayed a notable reduction in sport cognitive trait anxiety. Specifically, there was a decrease of 29.37% in social evaluation anxiety, 20.31% in competition preparation anxiety, 16.98% in performance anxiety, 25.16% in failure anxiety, 34.47% in opponent's ability anxiety, and 25.16% in injury anxiety. Moreover, for competitive state anxiety, cognitive state anxiety and somatic state anxiety decreased by 39.19 and 21.43%. The state self-confidence increased by 14.42%. Conclusion: The result indicated that systematic desensitization training not only mitigates anxiety but also positively intervenes in sports-related anxiety. Moreover, systematic desensitization training can significantly diminish competitive anxiety among Latin dance athletes to bolster confidence during competitions. Integrating desensitization training into the regular regimen of Latin dance practice has the potential to fortify dancers' psychological resilience against anxiety.

Regioselective quinazoline C2 modifications through the azide-tetrazole tautomeric equilibrium.

2-Chloro-4-sulfonylquinazolines undergo functional group swap when treated with an azide nucleophile: 1) the azide replaces the sulfonyl group at the C4 position; 2) the intrinsic azide-tetrazole tautomeric equilibrium directs the nucleofugal sulfinate from the first step to replace chloride at the C2 position. This transformation is effective with quinazolines bearing electron-rich substituents. Therefore, the title transformations are demonstrated on the 6,7-dimethoxyquinazoline core, which is present in pharmaceutically active substances. The methodology application is showcased by transforming the obtained 4-azido-6,7-dimethoxy-2-sulfonylquinazolines into the α1-adrenoceptor blockers terazosin and prazosin by further C2-selective SNAr reaction and azide reduction.

The Use of Dance and Movement for the Embodied Healing of Interpersonal Trauma in Women and Girls: A Systematic Review.

Interpersonal trauma is a pervasive issue with devastating consequences for women and girls of diverse identities. Research has shown that there are many potential physiological consequences for experiencing trauma, and as such, treatment for trauma should incorporate the body. Dance/Movement Therapy (DMT) has been emerging in the current literature as one body-oriented treatment approach effective in helping women and girls heal from interpersonal trauma. This review uses textual narrative evidence synthesis to examine how practitioners are currently using DMT for this population, what treatment outcomes have been observed, and what the racial/ethnic identities and international contexts are for survivors who have benefited from DMT. Inclusion criteria for the present review included peer-reviewed studies published in English between the years 2000 to 2022, reporting data on the use of dance or movement to help women and/or adolescent girls aged 12 and older heal from interpersonal trauma. Studies were identified through electronic databases, and 16 total studies met criteria. This review found that the characteristics and structure of DMT vary greatly between different practitioners, the participants of DMT are very diverse, and there are many commonly observed outcomes such as increased physical ability, increased emotional capacity, mind-body integration, safety, aid with trauma processing, empowerment, social support, and fun. This review also gives recommendations for practitioners who wish to utilize dance and movement in treatment: offer group interventions; use the body to create metaphor, imagery, and symbolism; give survivors choices in how they participate; use music purposefully; and don't forget to cultivate joy.

Dance with the senses. A dance class with visual impaired and sighted children in a conservatory: one-year experience.

BACKGROUND: Children with visual impairment very often have additional motor disorders and developmental delays. They are less active than typical children of a similar age, even though physical activity is essential for their well-being. METHODS: A weekly dance class for 1 year was offered to 4 visually impaired and 5 sighted children in a conservatory. RESULTS: The children's satisfaction was excellent, and they perceived an improvement in their mood, walking, balance and coordination, and felt more physically active. The walking speed, balance and posture were improved. CONCLUSION: This original project, with its full integration in a dance conservatory and by mixing children with and without visual impairment, showed excellent feasibility.

How spotting technique affects dizziness and postural stability after full-body rotations in dancers.

Consecutive longitudinal axis rotations are very common in dance, ranging from head spins in break dance to pirouettes in ballet. They pose a rather formidable perceptuomotor challenge - and hence form an interesting window into human motor behaviour - yet they have been scarcely studied. In the present study, we investigated dancers' dizziness and postural stability after consecutive rotations. Rotations were performed actively or undergone passively, either with or without the use of a spotting technique in such an order that all 24 ordering options were offered at least once and not more than twice. Thirty-four dancers trained in ballet and/or contemporary dance (aged 27.2 ± 5.1 years) with a mean dance experience of 14.2 ± 7.1 years actively performed 14 revolutions in passé or coupé positions with a short gesture leg "foot down" after each revolution. In addition, they were passively turned through 14 revolutions on a motor-driven rotating chair. Participants' centre-of-pressure (COP) displacement was measured on a force-plate before and after the rotations. Moreover, the dancers indicated their subjective feeling of dizziness on a scale from 0 to 20 directly after the rotations. Both the active and passive conditions were completed with and without the dancers spotting. As expected, dizziness was worse after rotations without the adoption of the spotting technique, both in active and passive rotations. However, the pre-post difference in COP area after active rotations was unaffected by spotting, whereas in the passive condition, spotting diminished this difference. Our results thus suggest that adopting the spotting technique is a useful tool for dizziness reduction in dancers who have to perform multiple rotations. Moreover, spotting appears most beneficial for postural stability when it involves less postural control challenges, such as when seated on a chair and occurs in situations with limited somatosensory feedback (e.g., from the cutaneous receptors in the feet). However, the unexpected finding that spotting did not help postural stability after active rotations needs to be investigated further in future studies, for example with a detailed analysis of whole-body kinematics and eye-tracking.

Can Dance Improve Turning in People With Parkinson's Disease?

Objective: To investigate the effects of a dance intervention on selected functional parameters during the 180° turning phase of the Timed Up & Go (TUG) test in people with Parkinson's Disease (PwPD). Methods: Fifteen adults clinically diagnosed with idiopathic PD were allocated into dance intervention (DIG; n = 7 ; age 73 ± 2 years) and control (CG; n = 8; age 64 ± 5 years) groups. The dance intervention lasted for 3 months (1 hour, twice a week). At baseline, all participants completed the Unified PD Rating Scale-part III, the International Physical Activity Questionnaire-short form, and the Hoehn & Yahr scale. Pre- and post-intervention, the primary outcomes were measured (number of steps and time to complete the 180° turning phase of the TUG test) at 2 speeds (comfortable walking and as quickly and safely speed) while using the Xsens® 3D motion suit. The secondary outcome (girdle dissociation) was assessed by calculating the difference between pelvis and affected shoulder orientation in the transverse plane (dissociation angles) at each data point during the TUG test's 180° turning phase. Results: At participant's comfortable walking speed, the functionality during the 180° turning remained unaffected following the dance intervention. However, at participant's fast speed, the dance intervention group significantly reduced the number of steps with a large effect size, and the total time taken to complete the 180° turning with a medium effect size. Post-intervention, most participants in the dance intervention group reduced the affected shoulder and pelvic girdle dissociation and turned more "en bloc." Conclusion: Dance can improve selected functional parameters during the 180° turning at fast speed in PwPD. The current results should be considered in rehabilitation programs.

Feeling safe together vs. longing for touch. Affective, multisensorial contact in inclusive intra-active virtual/physical dance during the COVID-19 pandemic.

This article explores how feelings of safety were experienced through inclusive virtual/physical dance in relation to experiences of touch during the COVID-19 pandemic in Finland. The following are the measures I took to achieve the aim of this study. First, I introduce the context through previous studies and an example from the ethnographic material I gained from the inclusive X-Dance festival organized in June 2021 in Finland. Second, I explore how inclusive virtual/physical dance might help us experience feelings of safety through multisensorial experiences of touch related to communality when responding to wellbeing challenges caused by isolation. Using Laura U. Mark's theory about haptic looking and Karen Barad's term intra-action, I discuss different possibilities to approach touch as a feeling sense, as affective multisensorial contact, and through relations between different materialities. Third, I contrast these ideas with sensations of longing for the physical touch that virtual/physical dancing evokes. These experiences of longing invite me to reflect on the ambivalence about feelings of safety related to intentions to restore experiences of touch and communality through digitality. I introduce two examples from my interviews with dancers during the pandemic to discuss these ambivalences. I reflect on these interviews through Magdalena Górska's theory about corpo-materiality and corpo-affectivity. I contribute to discussions on feelings of safety by showing that multi-sensorial experiences and anti-normative understandings of body and touch enabled by the non-verbal language of dance may help us to contribute toward more inclusiveness in society, allowing us to generate holistic experiences of safety, which is another critical aim for post-pandemic times.

Structured, Creative Dance Classes for Children with Developmental Disabilities: A Pilot Study of Feasibility and Preliminary Effect on Motor Function.

INTRODUCTION: Promoting physical wellness for preschool-aged children with developmental disorders (DD) is a known challenge. Interventions are more likely to succeed when physical activity opportunities are available to children within the context of their typical environments. We evaluated the feasibility and preliminary effect of 1 potential solution: structured creative dance classes delivered within a preschool environment. METHODS: Using a non-randomized feasibility study design, we offered physical activity in the form of creative dance classes for children with and without DD within an inclusive preschool. Classes lasted 30 minutes and were held once a week or 7 weeks. We measured attendance (primary), observed active participation (% of class duration), and balance (Pediatric Balance Scale). Non-parametric descriptive statistics are expressed as median (interquartile range). Balance was evaluated regarding (a) difference between groups at baseline (Mann-Whitney statistic) and (b) intervention effect for children with DD (1-tailed, paired t-test). RESULTS: Twelve preschoolers (age range = 3-5 years) participated: 4 with DD and 8 with neurotypical development. Attendance was 93% (79%-100%) for children with and 100% for children without DD. Per class, rate of active participation in dance activity was 33% (28%-45%) for children with and 80% (71%-82%) for children without DD. Starting balance scores were lower (P = .014) for children with DD (42 (39-45)) compared to those without (51 (50-52)). Post-intervention, balance scores improved for the children with DD to 50 (50-51) (df = 3, p = .014, t-statistic = 2.35); each child with DD surpassed minimal detectable change for balance. CONCLUSION: Creative dance classes, delivered within an inclusive preschool environment, are feasible for some preschool-aged children with DD to participate in and efficacious as a physical training challenge at low activity doses. More study is warranted of this potential solution to meet the need for physical wellness promotion among young children with DD.

Findings from a pragmatic cluster randomised controlled feasibility trial of a music and dance programme for community dwelling older adults.

INTRODUCTION: Functional decline, chronic illness, reduced quality of life and increased healthcare utilisation are common in older adults. Evidence suggests music and dance can support healthy ageing in older adults. This study explored the feasibility, potential for effect and cost effectiveness of the Music and Movement for Health (MMH) programme among community-dwelling older adults using a pragmatic cluster-randomised, controlled feasibility trial design. METHODS: Community-dwelling adults aged 65 years or older were recruited to seven clusters in the Mid-West region of Ireland. Clusters were block randomised to either the MMH intervention or control. Primary feasibility outcomes included recruitment, retention, adherence, fidelity, and safety. Secondary outcomes measured physical activity, physical and cognitive performance, and psychosocial well-being, along with healthcare utilisation were assessed at baseline and after 12 weeks. RESULTS: The study successfully met feasibility targets, with recruitment (n = 100), retention (91 %), adherence (71 %), data completeness (92 %) and intervention fidelity (21 out of 24) all meeting predetermined criteria. Both groups exhibited an increase in self-reported physical activity and improved physical function. Participants in the intervention group scored consistently better in psychosocial measures compared to the control group at follow-up. The health economic analysis confirmed the feasibility of the methodology employed and points to the potential cost-effectiveness of the MMH relative to the control or no organised programme. DISCUSSION AND IMPLICATIONS: The MMH intervention and study design were found to be feasible and acceptable with important findings to inform future evaluation of the clinical and cost-effectiveness of a definitive randomised controlled trial.

An Exploration of Low Back Beliefs of Male Pre-Professional and Professional Dancers.

BACKGROUND: Globally, male dancers are affected by low back pain (LBP) up to 2.5 times more than female dancers. While female dancers' beliefs around LBP and dance-specific low back movements exist, no research has explored male dancers' beliefs. This study aimed to (1) examine the low back beliefs of Australian male professional and pre-professional dancers, and (2) determine if beliefs toward common low back movements and lifting differed when current LBP or history of disabling LBP (DLBP) were considered. METHODS: 40 male dancers (mean age [SD] 26.9 years [7.9]) from a range of dance backgrounds (all participating in ballet) were recruited to complete a cross-sectional survey comprising a beliefs questionnaire considering dance-specific movement and lifting tasks, the Back Pain Attitudes Questionnaire (Back-PAQ) and the Athletic Fear Avoidance Questionnaire (AFAQ). Primary analysis included initial descriptives, a repeated measures ANOVA for movement-specific beliefs and visual thematic analysis for written responses within the belief's questionnaire. Secondary subgroup analysis included independent T-tests for those with/without current LBP and those with/without a history of DLBP. RESULTS: Fourteen dancers reported current LBP and 30 reported a history of DLBP. Dancers held generally negative beliefs toward the low back (Back-PAQ mean 123.1 ± 9.7) with neither subgroup demonstrating significant between-group difference (P < .05). Dance-specific flexion movements were seen as safer than extension movements (P < .05), and more extended-spine lifting was seen as safer than more flexed-spine lifting (P < .05). Dancers experiencing current LBP held less positive beliefs surrounding some dance-specific movements. CONCLUSIONS: Dancers hold negative general beliefs toward the low back irrespective of current or historical DLBP, however their beliefs surrounding dance-specific movements were relatively positive. Dancers' beliefs surrounding some movements were affected by the presence of current LBP, in particular an arabesque and a fish dive.

Brazilian dance self-perceived impacts on quality of life of people with Parkinson's.

Background: Parkinson's disease (PD) causes several motor and non-motor symptoms, resulting in negative impacts on physical, mental, emotional, and social aspects of people with PD quality of life. Dance has been considered as a potential non-pharmacological intervention to improve people with PD motor and non-motor symptoms, thereby enhancing quality of life. Purpose: To analyze the self-perceive impacts of Brazilian Dance on the quality of life (physical, mental, emotional, and social) of PwPD, both before and during the COVID-19 pandemic. Methods: Fourteen participants from the "Dança & Parkinson" project were included in this qualitative study. Data collection instruments consisted of a profile and personal data sheet; assessment of accessibility to the online dance classes; Telephone Montreal Cognitive Assessment by phone call; and semi-structured interview conducted through ZOOM video call. The participants characterization data were calculated using mean, standard deviation, and percentages with the Excel Program version 2013. Qualitative data was analyzed using the Thematic Analysis technique in the Nvivo, version 8.0, qualitative analysis of text, sound, and video program. Results: The participants reported facing various challenges in dealing with PD, which negatively impact their quality of life. However, their resilience, acceptance, and dedication to treatment play an important role in coping with the issues related to the disease. Brazilian dance, both in-person before the COVID-19 pandemic and online during the pandemic, led the participants to perceive improvements in physical, mental, emotional, and social aspects of quality of life. Conclusion: The Brazilian dance appears to have a positive impact on the physical, mental, emotional, and social aspects of the participants' quality of life, both before and during the COVID-19 pandemic.

Dynamic antennal positioning allows honeybee followers to decode the dance.

The honeybee waggle dance has been widely studied as a communication system, yet we know little about how nestmates assimilate the information needed to navigate toward the signaled resource. They are required to detect the dancer's orientation relative to gravity and duration of the waggle phase and translate this into a flight vector with a direction relative to the sun1 and distance from the hive.2,3 Moreover, they appear capable of doing so from varied, dynamically changing positions around the dancer. Using high-speed, high-resolution video, we have uncovered a previously unremarked correlation between antennal position and the relative body axes of dancer and follower bees. Combined with new information about antennal inputs4,5 and spatial encoding in the insect central complex,6,7 we show how a neural circuit first proposed to underlie path integration could be adapted to decoding the dance and acquiring the signaled information as a flight vector that can be followed to the resource. This provides the first plausible account of how the bee brain could support the interpretation of its dance language.

Effectiveness of dance movement therapy and dance movement interventions on cancer patients' health-related outcomes: a systematic review and meta-analysis.

OBJECTIVES: This review examined the effectiveness of using dance movement therapy (DMT) and dance movement interventions (DMIs) with cancer and palliative care patients. METHODS: A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Six databases were searched from inception to July 9, 2022, without limits on year or age. Searching was updated on July 10, 2023. The risk of bias was assessed by the Cochrane (RoB 2) and ROBINS-I tools. Meta-analyses were conducted to pool estimates of the effects of DMT and DMI on patients' health-related outcomes. A narrative synthesis of outcomes was performed where meta-analysis was not appropriate. RESULTS: Among a total of 16 studies included in this review, nine were randomized controlled trials and seven were non-randomized trials, with a total of 893 participants. Only six of these studies were fully or partially described as true DMTs (some with less clarity than others), whereas the majority (n = 10) were DMIs with unclear therapeutic alignment. Most studies focused on female patients with breast cancer. Cancer patients undergoing palliative care received little attention. The overall risk of bias from the evaluated studies was high. Meta-analysis of two trials revealed that DMTs had no effect on QOL in cancer patients (SMD - 0.09, 95% CI - 0.21-0.40, P = 0.54), while narrative analysis and non-randomized trials showed no overall effect of DMTs on anxiety, depression, body image, self-esteem, or sleep disturbance but significant positive effects on perceived stress, pain severity, and pain interference. DMIs had significant positive effects on cancer patients' depression (SMD - 0.53, 95% CI - 0.93 to - 0.14, P = 0.008) and fatigue (SMD - 0.42, 95% CI - 0.70 to - 0.14, P = 0.003). DMI trials synthesized narratively showed an effect on patients' body image, self-esteem, physical function, right and left handgrip strength, life satisfaction, and the mental component of QOL. CONCLUSION: Both DMT and DMIs had promising effects on several health outcomes, but results were inconsistent, and the evidence was weak. The reviewed studies' low evidence quality and small sample sizes affected the findings' robustness and reliability. Large-scale, high-quality randomized controlled trials with sufficient sample sizes, and clear and veracious DMT and DMI protocols and data are required to provide more credible research evidence and influence practice.

Experiences of people living with Parkinson's disease and key stakeholders in dance-based programs: a systematic review and meta-ethnography.

PURPOSE: To identify and synthesize qualitative literature on the experiences of participants and key stakeholders in dance programs for people living with Parkinson's disease. Synthesizing the available literature can generate new insights into participant experience to inform current and future programs. MATERIALS AND METHODS: Qualitative and mixed methods studies were identified via a systematic search of six databases: CINAHL, Web of Science, Scopus, SPORTDiscus, PsycInfo, and MEDLINE. Articles were synthesized using the meta-ethnographic method developed by Noblit and Hare (1988). Key concepts across studies were related via reciprocal translation, ultimately forming a line-of-argument synthesis. RESULTS: 26 articles met the inclusion criteria. Four interrelated, overarching themes were developed: (1) dance communities provide peer support and insight into living with Parkinson's, (2) feeling safe, accepted, and included in the dance experience, (3) overcoming dance-based challenges contributes to sense of achievement, confidence, and connectedness, and (4) dance participation is an opportunity to re-imagine oneself. CONCLUSION: Participant experience is shaped by the instructor-participant relationship, the social environment of classes, and class difficulty level. In order to support participant experience, classes should be safe, supportive, and have an appropriate challenge-skill balance. These qualities facilitate creative immersion and the potential for personal and collective change.

Physical activity can improve functional ability and quality of life in people living with Parkinson's disease (PD).Dance is a safe, enjoyable form of physical activity for people with PD that creates opportunities for meaningful social engagement and artistic expression.The quality of the instructor-dancer relationship, the wider social environment, and the challenge-skill balance contribute to dancer experience.For a dance class for people with PD to be successful, it must be safe, socially accepting, and provide opportunities for dancers to experience positive growth and a sense of achievement.
