Yeung analysis and Correlation between two samples

Details: Assignment 1

1) Refer to "The Use of Electro-Acupuncture in Conjunction with Exercise for the Treatment of Chronic Low-Back Pain" by Yeung, Leung, and Chow.

2) Complete "Yeung Analysis Worksheet."

3) Examine the question the researchers were trying to answer and write an essay (500-750 words) that explains why you feel the t-test was chosen. Choose one of the other tools studied so far in this course and explain why it would not provide relevant findings.

4) Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

5) This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.

What was the research question?

To determine the effect of a series of electro-acupuncture (EA) treatment in conjunction with exercise on the pain, disability, and functional improvement scores of patients with chronic low-back pain (LBP).

What were the independent variables?

What was the dependent variable?

IndependentàLBP

DependentàEA treatment

What was the sample size and how was it chosen?

Fifty-two (52) patients were entered to the study over a period of 12 months. None of them had undergone any back surgery before, and all subjects completed the treatment sessions

What was the experimental design and use of control group?

An additional concern regards the lack of placebo or sham acupuncture control group in this clinical trial, in that there was no control for the additional time and attention in the EA group plus exercise group

Were the instruments of measurement shown to be reliable and valid?

Yes

What data types were included?

Numeric

Describe the statistics used, what they were used for, and the results.

R-ANOVA, Independent t test,chi square test, and Separate

ANCOVA was performed to detect the difference between groups at any given time.

What were the researchers’ conclusions?How did they answer the research question(s)?

It is concluded that EA has an additional value to standard back exercise, and may be an effective option in the treatment of pain and disability associated with chronic LBP.

This study provides additional data on the potential role of EA in the treatment of chronic LBP

How was error controlled?

interaction between patient and acupuncturist was minimized to exclude potential

Did you see any concerns with the research study?If so, what?

Concerns about subjects’ long-term follow-up rate, meant that the follow-up period of the current study was 3 months after termination of the treatment series.

Therefore, onlythe immediate and medium-term effects were demonstrated, but the long-term benefits of EA were not examined in this study.
