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.

Self-Guided DMT: Exploring a Novel Paradigm of Dance Movement Therapy in Mixed Reality for Children with ASD.

Children diagnosed with Autism Spectrum Disorder (ASD) often exhibit motor disorders. Dance Movement Therapy (DMT) has shown great potential for improving the motor control ability of children with ASD. However, traditional DMT methods often lack vividness and are difficult to implement effectively. To address this issue, we propose a Mixed Reality DMT approach, utilizing interactive virtual agents. This approach offers immersive training content and multi-sensory feedback. To improve the training performance of children with ASD, we introduce a novel training paradigm featuring a self-guided mode. This paradigm enables the rapid creation of a virtual twin agent of the child with ASD using a single photo to embody oneself, which can then guide oneself during training. We conducted an experiment with the participation of 24 children diagnosed with ASD (or ASD propensity), recording their training performance under various experimental conditions. Through expert rating, behavior coding of training sessions, and statistical analysis, our findings revealed that the use of the twin agent for self-guidance resulted in noticeable improvements in the training performance of children with ASD. These improvements were particularly evident in terms of enhancing movement quality and refining overall target-related responses. Our study holds clinical potential in the field of medical treatment and rehabilitation for children with ASD.

The effect of dance on mental health and quality of life of people with Parkinson's disease: A systematic review and three-level meta-analysis.

OBJECTIVES: Parkinson's disease (PD) is a neurodegenerative disease that affects millions of individuals worldwide. Dance has emerged as a comprehensive intervention for enhancing well-being in this population. This meta-analysis aimed to assess the effectiveness of dance on mental health and quality of life among individuals with PD. METHODS: Three databases were searched in December 2022. Research papers comparing the effects of dance with a non-dance control on the quality of life or mental health of individuals with PD were included. Two authors independently screened the studies, extracted data, and assessed methodological quality of eligible studies. To address the interdependence of effect sizes within studies, the three-level meta-analysis approach was employed to analyze the data. RESULTS: Thirteen trials involving a total of 496 participants were included, with 11 being subjected to statistical analysis. The results indicated that dance had a positive impact on mental health (g = 0.43, 95 % CI = [0.11, 0.75]) and quality of life (g = 0.46, 95 % CI = [-0.04, 0.95]) when compared to passive control groups. Moderator analyses revealed that non-partnered dance and dance interventions with lower total dosages were particularly beneficial for mental health. CONCLUSION: Dance interventions are an effective lifestyle activity for enhancing mental health and quality of life in individuals with PD. A theoretical framework is proposed to explain the impact of dance on well-being from neurological, social, physical, and psychological perspectives.

A Safe and Feasible Online Dance Intervention for Older Adults With and Without Parkinson's Disease.

Introduction: Dancing is one way of maintaining an active lifestyle, and online dance interventions in group settings can be a solution when in-person classes are impossible. This study investigated the feasibility and potential clinical effects of an online dance program for older adults with and without Parkinson disease (PD). Methods: Participants attended 2 weekly dance classes in the same videoconference room for 2 months. The dance activities were mainly performed while seated (around 75%). Researchers monitored feasibility (ie, adherence, attendance, and technological barriers) and safety. Pre- and post-intervention assessments investigated self-perceptions, effects on emotional domains, quality of life, activity-specific balance confidence, lower-limb functional mobility, and PD non-motor symptoms. Individuals also reported their self-perceptions regarding technology usability, enjoyment, and social interaction. Results: Most of the participants with PD (n = 12) had moderate PD (Hoehn & Yahr score) and presented a greater risk of falls when compared to participants without PD (n = 14). Overall, we found a high rate of adherence (100%), attendance (87.5%-91.7%), and safety (100%) for both groups. No falls or near-falls occurred during the sessions. Only the PD group ameliorated emotional domains (anxiety and depression) and improved lower-limb functional mobility. All participants reported feeling safe and perceived benefits, although over a third of older adults with PD reported moderate difficulties in using technology and in socializing with the group. Conclusion: This online dance protocol is feasible, safe, and a potential strategy to improve clinical parameters in older adults and people with moderate PD.

The meaning and impact on well-being of bespoke dancing sessions for those living with Parkinson's.

PURPOSE: This paper presents qualitative research findings from the evaluation of a Parkinson's Dance well-being venture in the UK. METHODS: Qualitative data was gathered to see how bespoke dancing sessions helped people with Parkinson's (PwP) to manage their conditions and improve their lives and prospects. Principles of a participatory approach were incorporated and methods included semi-structured interviewing, researchers participant observation and an elicitation-based activity. Nineteen PwP, six carers, four dance artists and seven helpers participated in the study. RESULTS: Participating in Parkinson's Dance sessions meant that PwP could experience the possibilities to dance, develop a "can do" attitude, experience fun, enjoyment, social connection, exercise, movement to music, improvement and/or maintenance of their balance, suppleness, coordination and confidence with movement, symptoms being pushed back and ability to learn new things. CONCLUSIONS: Our findings add to the evidence-base about the benefits of dance for people experiencing Parkinson's and through novel application of the Life-world based well-being framework of K. T. Galvin and Todres (2011) we propose a theoretical basis for Parkinson's Dance as a resource for well-being. There is scope to consider application of the well-being framework to other arts activities and as the basis of an arts and well-being evaluation tool.

Utilization, Delivery, and Outcomes of Dance/Movement Therapy for Pediatric Oncology Patients and their Caregivers: A Retrospective Chart Review.

Children with cancer and their caregivers face physical and psychosocial challenges during and after treatment. Dance/movement therapy (DMT) has been used to improve well-being, promote healthy coping, and mitigate the impact of illness, but limited knowledge exists regarding DMT utilization, delivery, and outcomes in pediatric oncology. This retrospective study aimed to identify reasons for referral to DMT, DMT visit characteristics, key DMT techniques and processes, and clinician-reported outcomes. We examined the electronic medical records of 100 randomly selected pediatric patients (resulting in 1160 visits) who received DMT services between 2011 and 2021. Sociodemographic, clinical, and visit characteristics, referral reasons, and clinician-reported outcomes were reported as frequency and proportions. Qualitative thematic analysis was used to identify key DMT techniques and processes. Among 100 patients (63% female, aged 0-27 years), 77.9% were referred for psychological distress and 19.6% for pain. Two distinct DMT approaches were used during visits: a traditional DMT approach (77%) and a multisensory DMT approach (23%). The most common visit length was 15-25 min (41.6%), followed by sessions of 30-45 min (22.5%) and ≤10 min (18.1%). A total of 61.9% of DMT visits were inpatient and 38.1% outpatient. Of all visits, 8.8% were new and 91.2% were follow-ups. Caregivers were engaged in treatment in 43.7% of visits, and 5.5% of visits focused entirely on the work with the caregiver. DMT intervention focused on self-expression, emotional self-regulation, coping strategies, socialization, and caregiver-child interaction. Clinician-reported outcomes included enhanced coping with hospital experience (58%), improved pain management (27%), improved self-regulation (21%), and increased physical activation (13.2%). The results suggest DMT as a supportive intervention for psychological distress and pain management in pediatric oncology patients and provide insights into DMT practices and outcomes to guide intervention development and future research.

Impact of dance therapy on adults with psychological trauma: a systematic review.

BACKGROUND: Dance therapy is thought to improve mental and physical health by activating psychological and physiological processes such as motor coordination, and expression of emotions. Some currently used mind-body interventions for posttraumatic symptoms address both mental and physical health. Although some studies have evaluated the efficacy of dance therapy for posttraumatic symptoms, a systematic review of extant research has not been conducted. OBJECTIVES: To identify the effects of dance therapy in adults with psychological trauma as well as the barriers and facilitators associated with its therapeutic use. METHOD: Articles published between 2000 and March 2023 have been selected with the help of six relevant keyword combinations applied on seven databases. Two reviewers independently screened 119 titles and abstracts against inclusion and exclusion criteria. Bias evaluation has been conducted with the help of the NIH study quality assessment tools and JBI's critical appraisal tools. A report of the results has been organized with the help of a thematic analysis. RESULTS: Of the 15 articles included, only one case study directly reports a diminution of pathognomonic symptoms of trauma. Other studies present improvements in the key aspects of trauma therapy: bodily sensations and perceptions, psychological processes, and interpersonal skills. These improvements depend on the stability of the intervention, the applied method (dance as therapy or dance/movement therapy), and likely, the skill set of the therapists. However, the reviewed studies lacked uniformity in assessments of adherence and its effect on therapeutic outcomes. CONCLUSION: Dance therapy may be a useful technique for improving both psychological and physiological symptoms associated with trauma exposure, such as avoidance and dissociative phenomena. To complement the results of this qualitative systematic review, further quantitative and qualitative research on the impact of dance therapy interventions as a trauma treatment should be conducted.

Dance therapy may be a promising approach for the therapeutic management of psychological trauma as it can address both psychological and physical symptoms.Therapist skills and training may be important factors to consider in evaluating the impact of dance therapy on posttraumatic symptoms.Dance/movement therapy, a specific type of dance therapy, appears to be associated with improvements in sensory-motor perceptions and motor skills.To date, examination of dance therapy as a trauma treatment in an adult population has been limited primarily to women and people facing migration.

Evidence of the Effects of Dance Interventions on Adults Mental Health: A Systematic Review.

BACKGROUND: Recent research has shown that dancing takes effect directly in improving mental health, by reducing rates of depression, anxiety, and enhancing the mood aspects in people of any age. AIM: This systematic review aimed to search for evidence of the effects of dance interventions on adults' mental health. METHODS: The eligibility criteria of the studies were defined by following the PICOS strategy, considering the population, intervention, comparison, result, and the study design. Only randomized clinical trials, conducted in adults of both sexes, with results related to mental health, including depression and/or anxiety and/or stress and/or mood disorder were considered eligible for this review. The search was conducted using 5 databases: PubMed, Cochrane Library, Web of Science, Scopus, and ScienceDirect from 2005 to 2020. The Cochrane Collaboration tool was used to assess the risk of bias in randomized clinical trials. The synthesis and presentation of results followed the guidelines of the PRISMA model. RESULTS: Of 425 selected studies, 10 randomized clinical trials were included in the review with a total of 933 participants between 18 and 62 years old. Studies included Dance Movement Therapy, Latin dance, tango, rumba, waltz, Nogma, quadrille, and Biodanza. The results indicate that regardless of style, adults who participated in dance interventions showed a reduction in symptoms of depression, anxiety, and stress compared to groups that did not participate in any type of intervention. DISCUSSION: In general, studies showed an unclear risk of bias in most items assessed. Based on these studies, it is possible to assume that the practice of dance contributes positively to the maintenance or improvement of mental health in adults.

The effectiveness of dance movement therapy for individuals with Down syndrome: a pilot randomised controlled trial.

BACKGROUND: Individuals with Down syndrome (DS) exhibit deficits in static and dynamic balance abilities and maladaptive functions. This study aimed to determine the effectiveness of dance movement therapy (DMT) group intervention in individuals with DS. METHODS: The 31 participating individuals with DS, aged 5-29 years, were randomly divided into intervention (n = 16) and control (n = 15) groups. Posturography was used for static balance measurement, timed up and go test for dynamic balance measurement and the Achenbach System of Empirically Based Assessment (ASEBA) questionnaire for adaptive function and behavioural problem measurement in participants before and after the DMT interventions. The intervention group underwent 60-min DMT intervention once a week for 10 times, while the control group had usual daily activities. RESULTS: The results revealed a statistically significant difference and large effect sizes in dynamic balance [(f(1, 29) = 4.52, P = 0.04, ηp 2 = 0.14)] in the intervention group compared with the control group. There were no statistically significant differences in static balance and ASEBA scores between the groups. CONCLUSIONS: This study found that the DMT interventions helped to improve the dynamic balance in individuals with DS.

Physical activity based on dance movements as complementary therapy for Parkinson's disease: Effects on movement, executive functions, depressive symptoms, and quality of life.

BACKGROUND: Parkinson's disease (PD) is a progressive, neurodegenerative disease with motor symptoms that are well understood, but non-motor symptoms may be present and appear at different temporal stages of the disease. Physical activity based on dance movements is emerging as a complementary therapeutic approach to a range of PD symptoms as a multidimensional activity that requires rhythmic synchronization and more neuromuscular functions. OBJECTIVE: To evaluate the effects of physical activity based on dance movements on the movement, executive functions, depressive symptoms, quality of life, and severity of PD in individuals diagnosed with PD. METHODS: 13 individuals with PD (Hoehn & Yahr I-III, MDS-UPDRS 67.62 ± 20.83), underwent physical activity based on dance movements (2x week for 6 months). Participants were assessed at baseline and after 6 months on movement (POMA, TUG and MDS-UPDRS Part III), executive function (FAB), depressive symptoms (MADRS), quality of life (PDQ-39), and severity of PD (MDS-UPDRS TOTAL). Student's t-test was used to compare pre and post-intervention results. RESULTS: We observed a significant improvement in the movement (balance and gait) by the POMA test, p = 0.0207, executive function by the FAB test, p = 0.0074, abstract reasoning and inhibitory control by the FAB, Conceptualization test, p = 0.0062, and Inhibitory Control, p = 0.0064, depressive symptoms assessed by the MADRS test significantly reduced, p = 0.0214, and the quality of life by the PDQ-39 had a significant increase after the intervention, p = 0.0006, showed significant improvements between the pre-and post-intervention periods of physical activity based on dance movements. CONCLUSION: Physical activity based on dance movements contributed to significant improvements in movement (balance and gait), executive functions, especially in cognitive flexibility and inhibitory control, and the quality of life too. Sensorimotor integration, most cognitive processing and social skills may have contributed to the results. TRIAL REGISTRATION: The study was registered in the Brazilian registry of clinical trials: RBR-3bhbrb5.

Improving Postural Stability in Active Older Adults: Argentine Tango Dance as an Alternative Fall-prevention Strategy.

Context: Falls and the consequent injuries are a major global public-health issue, and fall prevention is urgently required for an aging population. Postural instability is a critical risk factor for fall prediction. Objective: The study intended to determine the impact of dancing the Argentine tango on postural stability in active older adults. Design: The research team designed a randomized controlled trial. Setting: The study took place in Ljubljana in Slovenia. The work was performed at two institutions, the Studio BA tango and the Institute of Sports Medicine. Participants: Participants were 36 active, healthy individuals aged between 65 and 70 years. Intervention: Eighteen dancing couples were randomly divided into two groups, the intervention and the control group. Both groups continued with their regular activities, but the intervention group also attended a 12-week program for 90 minutes twice a week dancing the Argentine tango. The class started with TangoFloorTec, a program that has been adapted for older adults, and continued with BA Tango Biomechanics. Each class ended with improvisational dancing and breathing exercises. Outcome Measures: The research team measured sway path on a force plate during the feet-together stance for 30 seconds and the one-legged stance for 20 seconds. Results: At baseline, no differences existed between the dancers and non-dancers in age, body mass index, or center of pressure. No falls were reported during the study. Twenty-eight participants, 7 couples in the intervention group and 7 couples in the control group, successfully completed the research protocol. Postintervention after 3 months of dancing, the intervention group had significantly better postural stability compared that of the control group (P ≤ 0.015). The effect of the intervention was large (ηp2: from 0.22 to 0.44). Conclusions: Dancing the Argentine tango can improve postural stability among already active older adults. Improved postural stability diminishes the risk of falling. The practical implication of the present study is that dancing can be more than just a hobby; it can serve as an alternative fall prevention strategy.

Dance interventions for individuals post-stroke - a scoping review.

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.

Impact of social media-based dance therapy in treating depression symptoms among victims of Russia-Ukraine war.

The objective of this study was to ascertain the impact of social media-based dance therapy in reducing symptoms of depression among evacuees of the Russia-Ukraine war. The participants were randomly assigned to no dance therapy (n = 162) and social media-based dance therapy groups (n = 162). The dance therapy group took part in 12 sessions of dance therapy while the no dance therapy group did not receive any intervention. The result showed that before the dance therapy intervention, participants in both groups reported severe depression symptoms. After the intervention, participants in the dance therapy group dropped from severe depression to normal depression while those in the no dance therapy group dropped to major depression. During the follow-up assessment after 3 months, participants in the no dance therapy group reported moderate depression while those in the dance therapy group still maintained their normal depression classification with a drop in their depression score from 46 to 26. Overall, the result showed that there was a significant main effect of time and the depression score of the participants, F(1,304) 203.143, p = 0.001, eta = 0.401. No interactive effect of gender and the impact of the treatment on reduction in depression symptoms was detected, F(1,304) 3.232, p = 0.073. However, there was a significant main effect of treatment condition on depression symptoms, F(1,304) 495.023, p = 0.001. We highlighted the implication of these results on health promotion.

Benefits of dance for Parkinson's: The music, the moves, and the company.

Dance classes designed for people with Parkinson's are very popular and associated not only with increasing individuals' motor control abilities but also their mood; not least by providing a social network and the enjoyment of the music. However, quantitative evidence of the benefits is inconsistent and often lacks in power. For a better understanding of the contradictory findings between participants' felt experiences and existing quantitative findings in response to dance classes, we employed a mixed method approach that focussed on the effects of music. Participant experience of the dance class was explored by means of semi-structured interviews and gait changes were measured in a within-subjects design through the Timed Up and Go (TUG) test before and after class, with and without music. We chose the TUG test for its ecological validity, as it is a simple test that resembles movements done in class. We hypothesised that the music and the dance class would have a facilitating effect on the TUG performance. In line with existing research, we found that before class, the gait of 26 participants was significantly improved when accompanied by a soundtrack. However, after class, music did not have a significantly facilitating effect, yet gait without music significantly improved after class compared to before. We suggest that whilst the music acts as an external stimulator for movement before the dance class, after the dance class, participants have an internalised music or rhythm that supports their motor control. Thus, externally played music is of less relevance. The importance of music was further emphasised in the qualitative data alongside social themes. A better understanding of how music and dance affects Parkinson's symptoms and what aspects make individuals 'feel better' will help in the design of future interventions.

Effects of Cha-Cha Dance Training on the Balance Ability of the Healthy Elderly.

Neuro-musculo-skeletal degradations with advancing age are generally accompanied with mobility problems and poor health status, contributing to impaired physical function and increased risk of falls. In an effort to diminish a fall-related risk such as unstable balance, a variety of interventions have been studied and implemented. Yet, there have been few studies to evaluate the effect of Cha-cha dance training on postural balance or balance performance of the elderly. The Cha-cha dance is composed of moderate rhythm and symmetrical movements and is easy to master and even easier for the elderly to begin. The purpose of this study was to intervene the fitness exercise through 12-week Cha-cha dance training, evaluate its impact on the balance ability of the elderly, and provide a scientific experimental basis for the elderly to participate in the Cha-cha dance exercise. Forty healthy elderly people with no difference in balance ability were randomly divided into two groups. The Cha-cha training group (CTG, n = 20) regularly participated in Cha-cha dance class, 3 times a week, 90 min each time, for a total of 12 weeks, and the control group (CONG, n = 20) did not participate in the class and engaged to their regular daily life. Dynamic and static balance were measured at pre and post intervention. Overall, the results showed that dynamic balance and static balance in CTG were significantly improved after the intervention. In addition, the results showed that the improvement was more significant in trials in left foot than right foot, and trials in closed eyes than open eyes, respectively. In conclusion, a 12-week Cha-cha dance class or program alone can be an effective intervention to improve balance of the elderly.

The Effects of a Dance and Music-Based Intervention on Parkinson's Patients' Well-Being: An Interview Study.

Previous research has shown the positive effects of music and dance-based interventions on the physical and psychosocial symptoms of Parkinson's disease (PD). The aims of this study were: (1) to investigate how PD patients subjectively perceive the emotional, cognitive, and social benefits of a music- and dance-based intervention; (2) to apply an innovative methodology for an interview analysis combining findings from a linguistic text with an analytic approach and conducted with the software LIWC and from the content analysis performed by human coders. Extensive, open-ended interviews were conducted with 13 patients with PD who had participated in a dance and music program. The interviews were analyzed using both human coders and the computer-based approach. The results show that emotional and social aspects are considered the most frequent perceived benefits of the dance program. The data confirm the positive impact of dance- and music-based programs on promoting participants' emotional and social well-being. A combined approach to text analysis appears to be a promising way to achieve more in-depth insights into patients' subjective perceptions.

Effects of dance therapy in women with breast cancer: A systematic review protocol.

BACKGROUND: Cancer is an important public health problem with an increasing global incidence in the recent decades. Breast cancer has become the leading cause of death in women worldwide. Women suffering from breast cancer, as well as survivors, may experience some adverse effects of treatment-including cancer-related fatigue, sleep disorders, and pain-which may manifest alone or in combination with other symptoms. Non-pharmacological interventions, such as physical activity, have been associated with improvements in these adverse effects. This study aims to evaluate the effects of dance therapy in women with breast cancer. METHODS: We will perform a systematic review according to the Cochrane methodology. An overall search strategy will be developed and adapted for PubMed, Virtual Health Library, PEDro, SciELO, SciVerse Scopus, Cochrane Library, and Web of Science using the descriptors "Dance therapy" or "Dancing" and "Breast neoplasms" or "Breast cancer." The size of the intervention effect (Z) will be calculated for each outcome included in this review. Outcomes will be pain, cancer-related fatigue, sleep disturbance, body image and depression in women with breast cancer. Quality assessment will be performed using the Cochrane instrument. Metanalysis, if plausible, will be performed using Review Manager 5.3. DISCUSSION: Studies have reported positive results of dance therapy as a non-pharmacological intervention in women with breast cancer. Thus, it is expected that robust and conclusive evidence of the effects of dance therapy during or after treatment (radiotherapy, chemotherapy, hormone therapy, and/or surgery) can be obtained. TRIAL REGISTRATION: Systematic review registration: CRD42020152876. (S1 File).

Analysis of Movement Entropy during Community Dance Programs for People with Parkinson's Disease and Older Adults: A Cohort Study.

Dance therapy can improve motor skills, balance, posture, and gait in people diagnosed with Parkinson's disease (PD) and healthy older adults (OA). It is not clear how specific movement patterns during dance promote these benefits. The purpose of this cohort study was to identify differences and complexity in dance movement patterns among different dance styles for PD and OA participants in community dance programs using approximate entropy (ApEn) analysis. The hypothesis was that PD participants will show greater ApEn during dance than OA participants and that the unique dance style of tango with more pronounced foot technique and sharp direction changes will show greater ApEn than smoother dance types such as foxtrot and waltz characterized by gradual changes in direction and gliding movement with rise and fall. Individuals participated in one-hour community dance classes. Movement data were captured using porTable 3D motion capture sensors attached to the arms, torso and legs. Classes were also video recorded to assist in analyzing the dance steps. Movement patterns were captured and ApEn was calculated to quantify the complexity of movements. Participants with PD had greater ApEn in right knee flexion during dance movements than left knee flexion (p = 0.02), greater ApEn of right than left hip flexion (p = 0.05), and greater left hip rotation than right (p = 0.03). There was no significant difference in ApEn of body movements (p > 0.4) or mean body movements (p > 0.3) at any body-segment in OA. ApEn analysis is valuable for quantifying the degree of control and predictability of dance movements and could be used as another tool to assess the movement control of dancers and aid in the development of dance therapies.

Dance Rhythms Improve Motor Symptoms in Individuals with Parkinson's Disease: A Randomized Clinical Trial.

BACKGROUND: Evidence-based practices involving dance modalities found in binary (two-beat rhythm) or quaternary (four-beat rhythm) show that dance positively influences the motor aspects of disease.
Aim: This randomized clinical trial aimed to analyze the effect of two dance rhythm (binary and quaternary) on the balance, gait, and mobility in individuals with Parkinson's disease (PD).
Methods: Thirty-one individuals with PD were randomized into the binary group (n = 18) and the quaternary group (n = 13). Both groups participated in different dance rhythms lasting 12 weeks, twice a week, for 45 minutes.
Results: The binary group showed a significant difference in balance (p = 0.003), freezing of gait (p = 0.007), as well as in the motor aspects of MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), with emphasis on the total values with a score change of 3.23. In the quaternary group, significant differences were found in balance (p = 0.021) with a score change of -2.54 and in the motor aspects of the MDS-UPDRS Part III where the total values stood out with a change of 3.54.
Discussion: When comparing the possible effects of binary and quaternary rhythms on the motor symptoms of individuals with PD, it was demonstrated that binary rhythm improved balance, freezing gait, and UPDRSIII. As for the quaternary rhythm, the benefits were in balance and the UPDRSIII.
Conclusion: The binary and the quaternary rhythm dance protocols positively influenced the motor symptoms of individuals with PD after 12 weeks of intervention.

The role of dance/movement therapy in the treatment of negative symptoms in schizophrenia: a mixed methods pilot study.

BACKGROUND: Optimizing psychosocial functioning by reducing the severity of negative symptoms are important outcomes for individuals with schizophrenia. Movement-based interventions could be uniquely capable of addressing the non-verbal nature of negative symptoms. AIMS: To examine the treatment effects of a 10-week group dance/movement therapy program on negative symptoms and psychosocial functioning of individuals diagnosed with schizophrenia. METHODS: A mixed methods intervention design (with explanatory intent) was used in which a randomized controlled trial was followed by semi-structured exit interviews. Participants diagnosed with schizophrenia (N = 31) were randomized to two conditions: treatment as usual (TAU) and dance/movement therapy (DMT). Before and after the program participants reported on negative symptoms and psychosocial functioning outcomes. Fifteen participants completed interviews. RESULTS: Quantitative data showed no improvement nor worsening of clinical status in the DMT group. Qualitative data suggested that participation in DMT had a physical impact, resulted in enhanced interpersonal connectivity, sense of integration, emotional support, and symptom management. CONCLUSIONS: Qualitative but not quantitative findings suggest that DMT has potential to enhance psychosocial functioning and to reduce severity of negative symptoms for schizophrenia.
