IntroductionThis the clinical practice as a potential treatment.

IntroductionThis article is titled “Physical
Activity for Osteoarthritis Management: A Randomized Controlled
Clinical Trial Evaluating Hydrotherapy or Tai Chi Classes”
and is published in the journal of the American College of Rheumatology
Vol. 57, No. 3, pp 407– 414 on April 15 2007. The head of the
research(author) Marlene Fransen,
is an Associate Professor at the Faculty of Health Sciences in the
University of Sydney and her research interest focuses on “It pursues a
body of clinical research developing cost-effective non-pharmacological
interventions to reduce the burden of pain and disability associated
with osteoarthritis”.The aim and rationaleThe rationale
of the research is to create a better research, looking for the
benefits of physical activity as the researcher(author) claims that
there is no good quality research to prove their benefits. The author
chose to investigate hydrotherapy and Tai Chi. According to the
first(hydrotherapy) the weight-relieving properties of water allow for
easier joint movement, which has not been proven due to poor quality
research.(h gnwmh mou edw einai oti tha mporouse na kanei mia ereyna mono gia thn ydrotherapeia prwta).
According to the second(Tai Chi) the author supports his choice to
study the Tai Chi as a treatment due to slow, continuous movements for
strengthening, balance, postural alignment, relaxation, and
concentration that consisted as well as the fact that there are not so
many researches that outnumber its benefits. Furthermore, according to
the author’s sources(hypothesis)
has been proven that the regular and moderate physical activity has
multifaceted health benefits and that people with knee and hip
osteoarthritis are usually sitting. The graded exercise programs is
asking for strength at both endurance training and aerobic exercise,
demonstrating a significant improvement in pain, physical functioning
and general health. (Arnhtiko gegonos se ayto apotelei h xamhlh

the above into consideration the author aims of the research
paper(experimental research) to determine whether Tai Chi or
hydrotherapy classes for individuals(59–85 yo) with chronic symptomatic
hip or knee osteoarthritis (OA) result in measurable clinical
benefits(pain and physical function as primary outcomes) in order to be
applicable to the clinical practice as a potential treatment.
