Outcomes

Primary Outcomes

Static Balance Performance-ALFA Stabilometric Platform

Time Frame: Baseline

Static balance performance will be assessed using the ALFA Stabilometric Platform. A static balance performance score generated by the device software will be recorded separately for each side during the assessment. Higher scores indicate better static balance performance.

Secondary Outcomes

  • Dynamic Balance Performance-ALFA Stabilometric Platform(Baseline)
  • Isokinetic Muscle Strength(Baseline)
  • Isokinetic Muscle Endurance(Baseline)
  • Pain Intensity(Baseline)
  • Kinesiophobia(Baseline)
