Study summary

In recent years, skeletal and nonskeletal effects of vitamin D has been studied. One of the effects of it was balance and fall prevention. However, these studies were performed on older patients who had not vitamin D deficiency. This study aimed to evaluate the effect of vitamin D replacement therapy and exercise on balance in 50-70 years-old postmenopausal women.

What researchers measure

Primary outcomes

  1. Postural Stability Test (Biodex) Assessed at Baseline

    overall stability index: quantifying the ability to maintain dynamic postural stability The patient's score on this test assesses deviations from center, thus lower index means less instability and better balance. Measures were obtained from 20-sec trials during which participants were asked to maintain an upright standing position on their dominant limb on the unstable surface of the Biodex Stability and Balance System. 0 is the minimum score, but there is no defined maximum score

    Time frame: Baseline

  2. Postural Stability Test (Biodex) Assessed After Treatment (8 Weeks)

    overall stability index: quantifying the ability to maintain dynamic postural stability. The patient's score on this test assesses deviations from center, thus a lower score is more desirable than a higher score. Measures were obtained from 20-sec trials during which participants were asked to maintain an upright standing position on their dominant limb on the unstable surface of the Biodex Stability and Balance System 0 is the minimum score, but there is no defined maximum score

    Time frame: After treatment (8 weeks)

  3. Berg Balance Test Assessed at Baseline

    14-item scale designed to measure balance of the older adult in a clinical setting minimum: 0 maximum: 56 A score of 56 indicates functional balance. A score of \< 45 indicates individuals may be at greater risk of falling.

    Time frame: Baseline

  4. Berg Balance Test Assessed After Treatment (8weeks)

    14-item scale designed to measure balance of the older adult in a clinical setting minimum: 0 maximum: 56 A score of 56 indicates functional balance. A score of \< 45 indicates individuals may be at greater risk of falling.

    Time frame: After treatment (8 weeks)

Secondary outcomes

  1. Fall Risk Assesment Performed at Baseline

    Biodex fall risk screening test: Patients were instructed to maintain the vertical projection with their center of gravity in the midpoint of the platform 0 is the best possible value, higher score reflects increased risk of falling. But there is no defined maximum score

    Time frame: Baseline

  2. Fall Risk Assesment Performed After Treatment (8 Weeks)

    Biodex fall risk screening test: Patients were instructed to maintain the vertical projection with their center of gravity in the midpoint of the platform 0° is the best possible value, higher score reflects increased risk of falling. But there is no defined maximum score.

    Time frame: After treatment (8 weeks)

  3. Health Status Assessed at Baseline

    Notthingham Health Profile: general patient reported outcome measure which measures subjective health status. 38 questions in 6 subareas, with each question assigned a weighted value; the sum of all weighted valuesin a given subarea adds up to 100. Overall score is calculated by summing up 6 subdomian scores. Ovearall minimum: 0 maximum: 600 (6X100) Higher scores reflect worse health status

    Time frame: Baseline

  4. Health Status Assessed After Treatment (8 Weeks)

    Notthingham Health Profile: general patient reported outcome measure which measures subjective health status. 38 questions in 6 subareas, with each question assigned a weighted value; the sum of all weighted valuesin a given subarea adds up to 100.
