Outcome Measures

Primary Outcomes (1)

  • Change in Short Physical Performance Battery (SPPB) Score

    SPPB measures lower extremity strength using 3 simple office-based tests to assess standing balance, gait speed, and chair stands. The composite SPPB score ranges from 0 (worst performance) to 12 (best performance). The minimal clinically important difference is not fully agreed upon, although a difference of 1.0 point has been used in many studies.

    Baseline and 6 weeks

Secondary Outcomes (1)

  • Change in Blood Level of Vitamin D (25-hydroxyvitamin D)

    Baseline and 6 weeks
