Study summary

This randomized controlled trial aims to compare the effectiveness of two different timings of physical therapy for individuals undergoing hemodialysis: intradialytic (during dialysis) and pre-dialysis (before dialysis). The study seeks to determine which approach provides better improvements in physical function, quality of life, and biochemical outcomes such as hemoglobin and electrolyte levels.

A total of 72 adult participants with end-stage renal disease (ESRD) receiving hemodialysis will be randomly assigned to one of two groups. Both groups will receive standardized educational sessions on the benefits and safety of exercise before beginning the intervention. Participants in the intradialytic group will perform supervised exercises during their dialysis sessions, while those in the pre-dialysis group will complete similar exercises before their dialysis sessions. Each participant will undergo the intervention twice per week for 12 weeks.

Primary outcomes include physical function, assessed using the Six-Minute Walk Test and the Five Times Sit-to-Stand Test. Secondary outcomes include hemoglobin levels, electrolyte balance, and health-related quality of life measured by the KDQOL questionnaire. The study will be conducted at Mubarak Al-Abdullah Al-Jaber Al-Sabah Dialysis Center, Kuwait, following ethical approval from the Ministry of Health Research Ethics Committee.

The results are expected to inform best practices for integrating physical therapy into dialysis care to enhance the health, safety, and well-being of individuals undergoing hemodialysis.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Intradialytic Physical Therapy (During Dialysis)

    Participants in this group will perform supervised physical therapy exercises during dialysis sessions twice weekly for 12 weeks (approximately 30 minutes each session, including warm-up, resistance training, and cool-down).

    Behavioral: Physical Therapy Exercise Program

  • Active comparator
    Pre-Dialysis Physical Therapy (Before Dialysis)

    Participants in this group will perform supervised physical therapy exercises before dialysis sessions twice weekly for 12 weeks, following the same exercise protocol and duration as the intradialytic group.

    Behavioral: Physical Therapy Exercise Program

Interventions

  • BehavioralPhysical Therapy Exercise Program

    A structured physical therapy program including warm-up, strengthening, balance, and stretching exercises delivered either during or before hemodialysis sessions (twice weekly for 12 weeks).

What researchers measure

Primary outcomes

  1. Six-Minute Walk Test (6MWT)

    Assessment of functional exercise capacity by measuring the total distance walked in six minutes.

    Time frame: Baseline, every 4 weeks during the 3-month intervention period, and at 6-month follow-up

  2. Quality of Life (Kidney Disease Quality of Life - KDQOL)

    Quality of life assessed using the Kidney Disease Quality of Life (KDQOL) questionnaire.

    Time frame: Baseline, every 4 weeks during the 3-month intervention period, and at 6-month follow-up

  3. Five Times Sit-to-Stand Test (FTSST)

    Assessment of lower limb strength and functional mobility by measuring the time required to complete five sit-to-stand repetitions.

    Time frame: Baseline, every 4 weeks during the 3-month intervention period, and at 6-month follow-up

Secondary outcomes

  1. Hemoglobin Level

    Measurement of hemoglobin concentration from blood samples.

    Time frame: Baseline, 4 weeks, 8 weeks, and 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2025 (actual). Primary completion is estimated for Mar 2027, 24 months after the start.

Of 347 non-industry interventional studies with no phase under Kidney Failure, Chronic, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 47. This study's planned 24 months is close to that.

Counting every sponsor, half of 425 studies reached it within 23 months; a quarter within 8 and three quarters within 46.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
