CASE STUDY 3
Kim,Chung, Park and Kang conducted a research where they proved thataquarobicexercises are beneficial to patients with osteoarthritisespecially with reducing pain, improving self-efficacy, improvingbody weight, depression levels and blood lipid levels. However, ifthey made a type I error the possible outcome for the osteoarthritisgroup would be that the aquatic exercise would not have the sameeffect on everyone therefore increasing the risk factors and makingpatients strain and experience more pain. Type I error indicatesthat a certain treatment works while the truth is it does not(Stommel, 2014).
Atype II error usually means that a said treatment does not existwhile in fact it does (Burns, 2015). Therefore in this case, statingthat the aquarobicexercises do not help patients with osteoarthritiswould mean that, researchers would have to go back to the drawingboard to look for more effective ways that the patients can behelped. Secondlypatients would go for a longer duration feeling painand opting to take medicinesas opposed to healthy aquarobicsexercisesthat would reduce their suffering greatly. A type II error could bereduced by conducting more research and making practical experimentswhere osteoarthritis patients can be taken throughaquarobic exercisesand the positive outcome shared widely.
Whencomparing the statistical significance of the findings with theclinical importance of the results one can see that there is not muchdifference as the statistics mirrors what the researchers gave intheir results (Kim et al 2012). Both the experimental group and thecontrolled group equally benefitted from the aqaurobic exercises. Oneof the weakness of the study was that it was somewhat biased sincethe patients were picked from one health center and thus this did notrepresent the entire Korean population. The strength of the researchwas that they took their time to conduct a thorough research. 12weeks of aquarobic exercises is enough to tell whether a patient isimproving or not.
