What researchers measure

Primary outcomes

  1. Numeric pain rating scale

    Numeric Pain rating scale is used to evaluate pain. It consists of 11 points, having score ranging from 0 to 10, where 0 represents no pain, 1-3 represents mild pain, 4-6 represents moderate pain and 7-10 represents severe pain.

    Time frame: From enrolment to end of treatment at 6 weeks.

  2. Berg Balance scale

    The Berg Balance Scale is a scale used to assess functional balance. It evaluates both dynamic and static balance through 14 tasks regarding mobility

    Time frame: From enrolment to the end of treatment at 6 weeks.

  3. Foot Function Index

    Foot Function Index questionnaire is used to measure the impact of foot pathology on pain, disability and activity restriction

    Time frame: From enrolment to end of treatment at 6 weeks.
