Did they show a significant difference between the control and intervention group?
What is yes.

Was a placebo aquatic therapy group used in this experiment?
What is no.

300
Participants were age what or over (45, 50, 60, or 75)?
What is 50.
300
The study had 71 participants. Did the authors believe the power from having this number of participants would be too small, just adequate, or more than adequate? “adequate”
What is adequate
300
What 2 muscle group strengths were assessed?
What is hip abductors and quadriceps femoris
400
Was this a single blind or double blind study?
What is single?
400
What type of randomization did they do (systematic, stratified, simple, cluster, convenience sampling, or blocked)?
What is blocked
400
What are some proposed benefits of hydrotherapy (name 2)?
What is reduction of edema, ease of movement, pain relief, patient confidence, decreased joint loading.
500
What did they do with the data of the 7 participants who dropped out of the study?
What is: They kept the data in, assigning them "no change" from their last visit forward.
500
What was the minimum pain score required to meet inclusion criteria (minimum score on the Visual Analog Scale)?
What is Greater than 3cm on a 10cm VAS.
500
After completing the 6-week program, how were the intervention group participants supposed to continue their therapy?
What is doing aquatic PT exercises (HEP) twice a week on their own.
500
Why did the authors think that a recent study that showed that aquatic therapy was no more beneficial than gym-based therapy or no intervention (in the same population of patients) was not a good study (Name 2)?
What is small # participants, no intention-to-treat analysis, water therapy not utilizing the principles of the water to maximize patient benefits from water.
500
For muscle strength tests, the MMT we learned qualify as “ordinal” data. These authors used a Nicholas Manual Muscle Tester. 1. What type of data did they get – nominal, ordinal, or continuous? 2. Would that (likely) make the data parametric or non-parametric? ***Double Daily bonus!
1. What is continuous data 2. What is parametric if the data is not skewed (OR non-parametric if the data is skewed).
