Food for thought on a new study (and infographic) about better hop hop reporting “Cite: Better reporting standards are needed to enhance the quality of hop testing in the setting of ACL return to sport decisions: a narrative reviewhttps: // bjsm .bmj.com / content / early / 2020/06/10 / bjsports-2019-101245 with subsequent infographics.
1️⃣ The first point the authors mention is that many studies do not report the test order, and whether this can affect the test results due to fatigue. But in my practice, it may be more important to test jump tests before strength tests so that the patient is not tired. Now, for example, I use MyJump2 App and I can see a decrease in jump height after each attempt. At Aspetar we have a 6 week test battery where the patient undergoes jump testing on a force platform and subsequent isokinetic testing. I would imagine that the jump tests would be affected if we did it the other way around. What do you guys think of the order of tests?
2️⃣The next point is reporting which leg will be tested first. Most people do not test the leg operated first and compare LSI.
3️⃣The third point is the break between tests where between 30 sec and 3min have been reported in included studies. Testing can be of lasting size, and if you have many tests, it can take a long time. For logistical reasons at a clinic, you would probably see shorter breaks. Maybe you should include test days in the rehabilitation plan where the patient needs to book a double session? What do you do at the clinics, find in testing time-consuming?
4️⃣The fourth point is which test result to take. Someone takes the best attempt based on 3 attempts. Others take the average of 3 attempts. What do you do? I personally would take the best result, but I have no specific considerations about it.
5️⃣Fifth point is about standard landing landing. The study mentions “Only six studies mentioned any landing requirements with descriptions ranging from ‘stable’, ‘controlled’, ‘without losing balance’ and either ‘hold for 2s’, or ‘hold for 2-3s’.” Personally, I use controlled landing. But it is a slightly vague wording. Maybe holding for 2s would be better? what do you think?
6th Sixth point is familyization and practice trials.
In relation to hop tests, I think there must have been a lot to gain from familyization. But could send the tests to patients 2 weeks before and ask them to practice. If you have practical tests in the same session, you may risk retiring the patient. What do you think about that?
7️⃣The seventh point is the standardization of heating. The study recommends general cardio activity (eg, stationary cycling or jogging performed at approximately 60% of maximum perceived effort) and 5 min task-specific activities such as squats, lunges, practice jumps / hops, etc.
Other considerations they make are the patient’s mental readiness on the test day, how to measure (for example, measure from toe to heel LSI in a hop test). In addition, studies may also consider reporting minimal detectable change (MDC) to exclude noise in the test.
