Study summary

ABSTRACT Objective: This randomized controlled double-blinded experimental study was carried out to determine the effects of daily exercise program on bone mineral density and cortisol level in preterm infants with very low birth weight matched for birth weight, gestation week, and gender.

Study design: The study was performed with preterm infants hospitalized in the neonatal intensive care unit of a tertiary hospital. Ethical committee approval, institutional permission, parental written consent were obtained. Daily exercise program was implemented in preterm infants in the exercise group for 30 days, once a day, and continuing for 7-10 minutes. Before and after the study the following were evaluated in preterm infants in the exercise and control group: anthropometric measurements, tibia speed of sound (SOS) for bone mineral density, serum biochemical parameters and cortisol levels.

Study arms

  • Experimental
    Exercise Group

    Daily exercise program involved "Range of Motion (ROM) exercises against extremity resistances" and "extension and flexion in upper and lower extremities." Exercises were implemented on wrists, elbows, shoulders, ankles, knees, and hip joints of the infants by the same researcher (YSE). The daily exercise program was repeated 5-8 times, 1 session/day (a similar time of the day), for 30 days. Each session continued for 7-10 minutes.

    Procedure: Daily Exercise

  • No intervention
    Control Group

    The preterm infants in the control group did not receive the daily exercise program, only the standard clinical routine.

What researchers measure

Primary outcomes

  1. Bone speed of sound values

    To measure SOS values, the preterm infant was placed on his/her back and his/her right leg was placed to obtain an angle of 900. The middle of the medial malleolus and distal patella apex was found and then gel was poured between the skin and the probe. The probe was put parallel to the bone to contact the point determined to be in the middle of the tibia and was moved from inside the leg. Afterward, the probe was placed from outside the leg toward the inside. In this study, The SOS from tibia was measured.

    Time frame: Change from bone speed of sound values at 30 days

Secondary outcomes

  1. Serum Cortisol levels

    serum biochemical parameters

    Time frame: Change from serum cortisol levels at 30 days

Ran from Apr 2016 to primary completion in Apr 2016, 0 months.

Of 114 non-industry interventional studies with no phase under Bone Diseases, Metabolic, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 35. This study's 0 months is below that.

Counting every sponsor, half of 129 studies reached it within 21 months; a quarter within 10 and three quarters within 35.

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 Dec 12, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
