Question: Question: Is three-dimensional speckle strain echocardiography more accurate and efficient than 2D strain in the evaluation of left ventricular function?

Answer: yes


Question: Question: Do armband activity monitor data correlate with reported pain scores in patients receiving vertebroplasty?
Answer: Activity monitors can be used to objectively record changes in activity following vertebroplasty procedures. Patient-reported pain or disability scores do not correlate with activity monitor-measured activity or sleep metrics.

Answer: no


Question: Question: Does mini-midvastus total knee arthroplasty result in superior gait pattern?
Answer: From our findings, it was concluded that MIS TKA does not result in a superior walking pattern 8 weeks post-operative. Because we previously also observed mini-midvastus MIS TKA to have equal or slightly inferior results with regard to knee scores, knee torque, radiographic outcome and tourniquet/operating time, we discontinued the procedure.

Answer:
no
