Physical functional performance and clinical relevance outcome measures
| Outcome | Assessment tool | Procedures |
| Physical functional performance | ||
| Hop distance (single Leg) | Single Leg Hop for Distance Test29 | Patients are instructed to stand on the leg being tested, hop and then land on the same limb, jumping as far as possible. The distance hopped is measured at the level of the great toe and recorded to the nearest centimetre using a standard measuring tape fixed to the floor. Both lower limbs are evaluated for comparison. |
| Stairs (ascent/descent) | Stair Climbing Test30 | Patients will be timed as they ascend and descend a flight of 12 stairs as quickly as possible. The number of steps they perform in 30-second intervals will also be counted. |
| Clinical relevance | ||
| Symptom state | Patient Acceptable Symptomatic State21 | Patients provide their perspectives on the final Patient Reported Outcome Measures (PROM) scores, which indicate their satisfaction with symptoms. For each PROM score, patients are asked a question with the answer option ‘yes’ or ‘no’. |
| Clinical benefit | Substantial Clinical Benefit21 | Patients are surveyed to gather their perspective on the change in PROM scores that indicates a significant or optimal improvement. For each change in score, patients are asked a question with answer options displayed on a 7-point Likert scale, ranging from ‘significant and marked improvement’ to ‘no improvement at all’. |
| Clinical difference | Minimal Clinically Important Difference (MCID)21 | The patients will be asked about their opinion on the minimum change in PROM scores that would significantly improve their condition. We will use an anchor-based technique to determine the MCID. |
