Research on the most effective and cost-effective methods of physiotherapy training for improving chronic lower back pain outcomes can use a multitude of different designs. During the course of my search for evidence, I expect to find several meta-analyses of the literature as well as a variety of qualitative and quantitative designs. Because I am exploring treatment/intervention efficacy as well as cost-effectiveness, designs will range from experimental and quasi-experimental to cohort and case study designs. A meta-analysis of the literature on interventions would help to illuminate specific issues like the cost effectiveness of target interventions, as well as measurable patient outcomes. The meta-analyses will be systematic, taking into account published studies using a range of different variables. However, ultimately a cohort design would be optimal for gathering initial data. Cohort designs are likely to be ubiquitous in the literature on the treatment efficacy of specific physiological interventions for lower back pain. As Song & Chung (2011) point out, cohort designs are frequently used in medical research because “a well-designed cohort study can provide powerful results,” (p. 2235). The methods used generally entail studying a disease-free population sample (in this case, a sample without back pain) over time, to determine the effectiveness of the intervention...
This way, the same population can be evaluated to determine treatment efficacy. Unfortunately, the cohort design will be less effective at addressing the financial outcomes of the target interventions.References

Topic: 1 My research is being designed to investigate the efficacy of a culturally appropriate and targeted diabetes education program on the reduction of A1C levels after six months. The population I am focusing on is Asian Americans with Type II diabetes, within a specific age range. My hypothesis is that after three months of the program, the A1C levels of the experimental group will be lower than they were prior
Experimental Research Methods in Business Experimental Research Methods The author provides a survey of the literature illustrating applied experimental research methods in cross-sections of business and organization types. The advantages and disadvantages of the experimental research methods are discussed for each of the examples provided which run the gamut from depression-era agricultural economics to research conducted for the National Science Institute. While the article focuses on business research methods, the range of
The strengths of this design are related to the ease of application and usage. The design of the survey was easy to administer and self explanatory. While the weakness was related to the willingness of the participant to Chapter Three 5 participate complete the survey and provide truthful responses. An additional weakness is relative to the age group that was present for the survey and their relationship to the use of
Experimental design employs comparison as its strategy for the given research. It uses two groups, which the researcher uses for comparison purposes. These include the experimental group and a control group. The two groups used in a study have similarities, but the experimental group uses the independent variable, whereas the researcher the control group is not assignment of subjects to either control or experimental group because it is central to

This reduces response bias for better reliability of the information gathered and a higher anticipated response rate for an adequate sample size. A one month time frame gives better assurance of an appropriate response rate adequate analysis of results.
