Trial summary

Studies have demonstrated that brief (5-10 min a day) passive range-of-motion exercise is beneficial for bone development in very low birth weight (VLBW) preterm infants. However, the optimal duration and frequency of exercise for bone development in preterm infants is yet unknown. Read more about this study

About this study

Official title: The Effect of Physical Activity on Bone Strength and Immune System in Very Low Birth Weight Infants: is More Really Better??

Studies have demonstrated that brief (5-10 min a day) passive range-of-motion exercise is beneficial for bone development in very low birth weight (VLBW) preterm infants. However, the optimal duration and frequency of exercise for bone development in preterm infants is yet unknown.

The effect of exercise on the immune system was widely studied in adult and children. Exercise induces increase in IL-6, IL-10, and IL1ra. In adult even 10 minutes of flexion and extension of the wrist cause systemic increase in IL-6. The effect of physical activity on pro and anti inflammatory cytokines in preterm infant was not studied.

Objectives:

  1. To assess weather twice daily exercise intervention will enhance bone strength compared to once a day intervention
  2. To evaluate the effect of a single exercise intervention on inflammatory mediators.

Methods:

Single center (Meir Medical Center), double blind, randomized control study.

Read the detailed description

Infants will be randomly assigned to one of 3 study groups. Group 1 - physical activity once a day. Group 2 - physical activity twice a day and group 3 - control.

The physical activity program is based on the Moyer-Mileur et al protocol (1). Briefly, this protocol involves extension and flexion range-of-motion exercise against passive resistance of both the upper and lower extremities. Both extension and flexion were performed five times at the wrist, elbow, shoulder, ankle, knee, and hip joints (about 10 minutes for each session). Infant in group 1 have the physical activity intervention once a day, 5 days a week. Infant in group 2 will have the same physical activity intervention twice a day, five times a week. Infant in group 3, the control group will have a similar time (10 minutes) of daily interactive periods of holding and stroking without range-of-motion activity.

The physical activity will be done by the same person (the NICU physiotherapist) Growth parameters, and bone strength, will be measured at enrollment and every 2 weeks till discharge.

Bone strength assessment will be determined by quantitative ultrasound measurement of bone speed of sound (SOS) at the middle left tibial shaft (Sunlight Omnisense Premier). All measurements will be performed by the same person, who will be blinded to the group assignment.

Cytokines study In a sub-group of patients who will have arterial line at enrollment blood sample ( 0.6 CC) will be drawn before and immediately following activity for assessment of proinflammatory (IL-6) and anti-inflammatory ( IL1-ra) cytokines. Samples will be kept at -20º C and will be analyzed after completion of the study.

Questions about this trial

What is this clinical trial studying?

A study testing passive physical activity in people with Osteopenia of Prematurity, run by Meir Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ita Litmanovitz, MD (+972-9-7471554, litmani@clalit.org.il), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bone Speed of sound (time frame: during hospitalization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01042639, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2012.
