A scoping review of the effectiveness of underwater treadmill exercise in clinical trials of chronic pain
Bibliographic record
Abstract
OBJECTIVE: The objective of this scoping review was to investigate the available literature on physical and quality of life (QoL) outcomes of underwater treadmill exercise trials in clinical chronic pain samples. METHODS: A scoping search of studies of the effectiveness of underwater treadmill exercise trials from 1947 to 2024 was conducted using the following databases: EMBASE, MEDLINE, SPORTDiscus, CINAHL, and Cochrane Reviews. To be included, studies were required to have included adult participants living with chronic pain (defined as pain lasting for 3 months or longer) who participated in an active underwater treadmill exercise intervention. No restrictions on pain diagnosis were applied. All clinical trials, including but not limited to randomized controlled trials (RCTs), feasibility trials, and pilot studies, were included in the search. Two independent reviewers determined whether studies met inclusion criteria, and a third reviewer resolved any disagreement on study inclusion. RESULTS: The initial search identified 2,209 studies: 314 articles were removed for duplications, 1,781 were removed because they did not meet inclusion criteria, and 113 were retained for full-text review. The full-text review yielded nine studies, all of which included samples consisting of participants with osteoarthritis. The following variables were investigated in the included studies to varying degrees: pain, QoL, mobility, balance, strength, and changes in gait kinematics. Multiple studies identified significant differences between control groups or pre-intervention groups and underwater treadmill groups or post-intervention groups in chronic pain, balance, mobility, strength, and QoL. CONCLUSION: Findings suggest that underwater treadmill exercise leads to positive changes in chronic pain, balance, mobility, strength, and QoL. However, more studies, particularly RCTs with larger samples that include individuals with chronic pain conditions other than osteoarthritis, are warranted.

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.
