In the study conducted by Yeung, Leung, and Chow, the primary research question revolved around evaluating the effectiveness of electro-acupuncture combined with exercise therapy in alleviating chronic low-back pain (CLBP). The researchers aimed to determine whether this combined treatment approach produced statistically significant improvements in pain levels and functional ability compared to control groups receiving either alone or standard care. To answer this question, the researchers needed to analyze quantitative data collected from clinical assessments, pain scores, and functional tests pre- and post-intervention.

The choice of the t-test as the primary statistical tool in this research was appropriate due to its capacity for comparing the means between two groups or conditions. Specifically, the t-test is used to determine whether there is a statistically significant difference between the means of two independent groups, such as a treatment group receiving electro-acupuncture plus exercise and a control group receiving only exercise or placebo. This method is suitable when the data are continuous, normally distributed, and the sample sizes are relatively small, which is often the case in clinical studies of this nature. The t-test's sensitivity to detect differences in means makes it an ideal choice for assessing the efficacy of interventions in experimental and clinical research contexts where the goal is to establish causality or the effectiveness of a treatment protocol.

Moreover, the paired t-test could have been used if the study design involved comparing pre- and post-treatment measures within the same group of participants. This would help determine whether individuals experienced significant improvements following the intervention. The t-test offers a straightforward statistical approach that provides clear insights into whether the interventions had statistically meaningful effects, which is essential for evidence-based clinical decision-making.

In contrast, one of the other tools studied—such as analysis of variance (ANOVA)—would be less relevant in this context if the comparison is primarily between two groups or two related measures. Although ANOVA can handle multiple groups or conditions simultaneously, it is more complex and more appropriate when comparing three or more groups or factors. For the specific question of whether electro-acupuncture combined with exercise significantly improves outcomes compared to a control, the t-test is more direct and sufficiently robust, reducing computational complexity and interpretation difficulties associated with more complex analyses.

In conclusion, the t-test was chosen because it is ideal for comparing the means of two independent or related groups to ascertain the statistical significance of treatment effects in this clinical context. Its appropriateness hinges on the nature of the data, the study's design, and the research focus on evaluating the difference between two treatment modalities. Other tools like ANOVA would not provide relevant findings unless the study involved multiple groups or factors, making the t-test the most straightforward and effective statistical method for this research question.
