What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tested whether adding mental tasks (like counting backwards or naming words) to water-based exercises helps healthy older adults improve both thinking and balance. Eighty-four adults aged 65+ did either water exercises alone or water exercises combined with cognitive challenges for 12 weeks. The group that did both showed better gains in memory, attention, and balance compared to those who only exercised.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Aquatic dual-task training (water exercises combined with cognitive tasks)
What this could lead to
If this approach works, it could offer a simple, enjoyable way for older adults to maintain both physical and mental sharpness, potentially reducing fall risk.
What could go wrong
This was a small, completed trial in healthy older adults, so results may not apply to those with existing cognitive decline. The improvements were modest and need confirmation in larger, longer studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 65 years or older. * Cognitively preserved, defined as a Mini-Mental State Examination (MMSE) score equal to or above reference values adjusted for education: illiterate ≥16; 1-11 years of schooling ≥23; more than 11 years ≥28. * Prior experience of 3-6 months with regular aquatic physical therapy (2 sessions per week) to ensure familiarity and adaptation to the aquatic environment. * Medically cleared to perform moderate-intensity aquatic exercise, confirmed by: * Orthopedic Assessment: No severe musculoskeletal conditions preventing safe participation. * Clinical Risk Classification: Low to moderate risk according to the American College of Sports Medicine (ACSM) Risk Stratification. * Functional Capacity: Duke Activity Status Index score ≥7. Exclusion Criteria: * Requirement for walking aids, as this interferes with safety and exercise execution. * Previous diagnosis of progressive and severe neurological diseases, such as Parkinson's disease, Amyotrophic Lateral Sclerosis, or dementias, that could compromise response to intervention. * Clinical conditions preventing safe aquatic exercise, including unstable cardiovascular disease, urinary or fecal incontinence, transmissible infectious or dermatological diseases, severe psychiatric disorders, severe respiratory conditions, or acute musculoskeletal limitations. * Participation in other physical or cognitive training programs during the intervention period. * Inability to understand or sign the informed consent form.
