Active group-based performing arts interventions in Parkinson’s disease: an updated systematic review and meta-analysis
Bibliographic record
Abstract
OBJECTIVES: To assess the evidence for active group-based performing arts interventions for people with Parkinson's disease (PD). SETTING: Scholarly literature (published in English) from any country or countries (last search February 2025). This systematic review was not registered and received no funding. DATA SOURCES: Five bibliographic databases: AMED (Ebsco), APA PsycINFO (Ovid), CINAHL (Ebsco), EMBASE (Ovid) and MEDLINE (Ovid), plus supplementary searches. PRIMARY AND SECONDARY OUTCOME MEASURES: Eligible studies used a quantitative design to assess the benefit of active group-based performing arts interventions on quality of life, functional communication, speech, motor function and cognitive status in PD. The risk of bias was assessed using the SURE, University of York Centre for Reviews and Dissemination and Newcastle-Ottawa Scale checklists. Data were synthesised using narrative synthesis and random-effects meta-analysis. RESULTS: A total of 94 studies were included: 2453 people with PD (mean age 68 years, 55% male) from 18 countries. Narrative synthesis supported nine combinations of performing arts modalities and outcome domains, including a benefit for dance on motor function (supported by 50 out of 54 studies), dance on quality of life (supported by 24 out of 37 studies) and singing on speech (supported by 17 out of 20 studies). Meta-analysis supported five combinations of performing art modalities, comparators and outcomes, including a clinically significant benefit for PD-specific dance versus usual care PDQ-39, MD -7.81, 95% CI -11.87 to -3.75 and tango-based dance versus usual care on UPDRS-III, MD -9.89, 95% CI -16.65 to -3.13. CONCLUSIONS: Evidence from both the narrative synthesis and the meta-analysis supports a benefit for some combinations of performing arts modalities and outcomes. Limitations of the evidence base included differences in comparators and outcomes, heterogeneity, lack of control arms and male underrepresentation. Future studies should compare the effectiveness of different performing arts modalities, assess functional communication and consider clinical significance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
