Introduction
For optimum patient care, it is important to rely on well-researched work so as to obtain
reliable evidence to assist in making an optimal decision on the anticipated method to be used by
the patient. Evidence-based practice incorporates studies that have been extensively and
adequately carried out by skilled researchers on patient's circumstances, values, and outcomes
regarding a technique under consideration. However, the studies differ considerably on their
credibility and quality because of the difference in researchers' knowledge and skills. Tasso's
case study will be used in the essay to summarize the important evidence-based practice phase of
critical review, to ensure that the best evidence available is used to answer the Tasso's question:
what experiences do men with post-traumatic disorder get when taking yoga as a treatment
option to improve their current status? The essay will critically examine quantitative and
qualitative research to establish their reliability and rigor, through identification of the main
study aims, design, evaluation of authorship and findings. The essay will then scrutinize the
barriers to implantation of evidence and come up with a conclusion regarding the article that
responds best to Tasso's question (Johnston, Minami, Greenwald, Reinhard & Khalsa, 2015).
PART A
Strengths and Limitations of the study
According to the study the researcher's strengths and limitations outlined as follows. The
strength include; authors use of randomly selected sample to represent the population which
increased the accuracy of the study, the participants in the study were not homogeneous but
represented the diversity of the population, the use of primary information obtained directly from
participant improves the accuracy and reliability of the data when it comes to making conclusion

of the study, use of randomized control trial to improve the efficacy of yoga among the
participants and data collection methods used by the researcher provided a consistent and precise
data for the study (West, Liang & Spinazzola, 2017). There is no identifiable conflict of interest
in the case study. The research was approved and funded by the university’s office of research
and ethics. Author's limitations include; the yoga intervention did not consider a long period of
follow-up to access whether it has a long-term effect on the participants, the result of the study
was greatly influenced by yoga group attrition, the size of the sample was small which impaired
the extent of generalization for the study, the control group was inactive hence test of yoga to the
participant was almost a mere speculation and lastly, there was no consideration of
physiological, ethnic and gender variables of the population which are major aspects of the study
(Jindani & Khalsa, 2015).
Research questions
Research questions assist the researcher to outline the objectives, aims, and goals of the
research. The research questions are significant because they help the researcher to be major on
the important events as they undertake the research hence giving the general view of the study.
Due to the unique challenges related to post-traumatic stress disorder the researcher carried out a
study to find out whether yoga class could be used to address these challenges effectively. The
relevant research questions for this essay include; does undertaking of yoga improve the
wellbeing of people who have post-traumatic stress disorder? What are the alternative methods
available for the patients to use? How efficient is the use of yoga compared to other methods of
improving the wellbeing of post-traumatic stress disorder? Are there any side effects of
undertaking or joining yoga classes? And how long should the patient attend the yoga class to
improve the current condition?. The post-traumatic disorder is a threat to the people who have
