Activity Levels in Bone Marrow Transplant Patients
What this study is about
Participants in this study will be receiving a bone marrow transplant. This study is designed to evaluate correlations between activity levels and length of stay, quality of life, and hand grip strength.
View original scientific description
Participants in this study will be receiving a bone marrow transplant. This study is designed to evaluate correlations between activity levels and length of stay, quality of life, and hand grip strength.
Interventions
DEVICE
Actigraph
Actigraphs are non-invasive, wearable devices that measure activity levels using an accelerometer
OTHER
Grip strength test
The purpose of this test is to measure the maximum isometric strength of the hand and forearm muscles
Primary outcome measures
To determine the correlation between activity levels and length of stay in hospital
Time frame: From study intitiation for up to 5 years
Participants will be given actigraphs to wear around their waists starting 3 weeks prior to bone marrow transplants until they are discharged from the hospital. Activity prior to and during hospitalization will be correlated with length of stay.
To determine the correlation between activity levels and quality of life
Time frame: From study intitiation for up to 5 years
Participants will be given actigraphs to wear around their waists starting 3 weeks prior to bone marrow transplants until they are discharged from the hospital. They will be provided with quality of life questionnaires at three time points during hospitalization. Activity prior to and during hospitalization will be correlated with quality of life
To determine the correlation between activity levels and hand grip strength
Time frame: From study intitiation for up to 5 years
Participants will be given actigraphs to wear around their waists starting 3 weeks prior to bone marrow transplants until they are discharged from the hospital. Hand grip strength will be measured at three time points during hospitalization. Activity prior to and during hospitalization will be correlated with hand grip strength.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
