Hydrotherapy tub article review

I am reading this artcile (see attached file) and have come up with a few points where I agree with the author and a few points where I disagree.  When Discussing it with fellow classmates, many of us have come up with similar arguments.  I don't like to be  the same, and am hoping an OTA can help identify three other points that they feel could be addressed in the article.  

I am to crtically review this paper and identify points that are good and points that are bad (some points as presented by the authors might be wrong, inaccurate, inappropriate or not substantiated); e.g., are the concerns valid? Are the recommendations logical/reasonable? Is the background information accurate, etc.?

I am also to use other referenced articles/resources/publications to support my opinion/comments, i.e., my likes and dislikes

I thank you for your help...
