Outcome Measures

Primary Outcomes (1)

  • Proprioception Measurement

    During the measurement, the inclinometer was positioned over the proximal one-third of the fibula, with its axis aligned with the knee joint line, and secured using a strap. Measurements were performed in both the prone and sitting positions. Participants were instructed to actively move their knee from 90° of flexion toward the target position of 30° of flexion. Upon reaching the perceived target position, participants maintained the position for 5 seconds before returning to the starting position.

    Each measurement was repeated three times, with a 1-minute rest interval between trials. A 2-minute rest period was provided between the two testing positions to allow participants to change position and rest.

Study Arms (2)

Knee Osteoarthritis Group

Participants diagnosed with knee osteoarthritis.

2-True Control Group

Participants without a diagnosis of knee osteoarthritis.
