Research Literacy and Evidence-Based Practice Flashcards

Evidence-based practice (EBP) in massage therapy is best defined as the integration of:

Answer: Best available research evidence, the therapist's clinical expertise, and the client's values and preferences

Evidence-based practice has three pillars: (1) best available research evidence, (2) the practitioner's clinical expertise and judgment, and (3) the client's values, preferences, and goals. All three must be integrated for truly evidence-based clinical decision-making.

In a randomized controlled trial (RCT) on massage for neck pain, participants are randomly assigned to massage or a control group. The PRIMARY purpose of randomization is to:

Answer: Minimize selection bias and balance known and unknown confounding variables between groups

Randomization distributes both known and unknown confounding variables evenly between groups, so that differences in outcome can be attributed to the intervention rather than pre-existing group differences (selection bias). This is why RCTs are considered a high standard for establishing causation.

A study reports that massage reduces anxiety with a p-value of 0.04. What does this p-value indicate?

Answer: There is a 4% probability that the observed result occurred by chance if there were truly no effect

A p-value represents the probability of obtaining the observed results (or more extreme) by chance alone, assuming the null hypothesis is true. A p-value of 0.04 means there is a 4% chance the result is due to random variation — below the conventional 0.05 threshold, making it statistically significant.

A systematic review differs from a single research study primarily because it:

Answer: Synthesizes and critically evaluates all available studies on a focused research question using explicit, reproducible methods

A systematic review uses a pre-defined, transparent methodology to identify, critically appraise, and synthesize all relevant studies on a specific question. This provides broader and more reliable evidence than any single study. When combined with meta-analysis, it sits at the top of most evidence hierarchies.

Which of the following represents the LOWEST level of evidence when evaluating whether a massage technique is effective for a specific condition?

Answer: An expert opinion or anecdotal case report

Evidence hierarchies rank study designs by their ability to control for bias. Expert opinion and case reports sit at the bottom because they lack controls, randomization, and systematic methodology, making it difficult to attribute outcomes to the intervention. Systematic reviews with meta-analysis provide the highest level of evidence.

A client states they read online that a specific massage technique 'cures' fibromyalgia. The evidence-based response from the massage therapist is to:

Answer: Evaluate the quality of the evidence for that claim and refer the client to their physician for diagnosis and medical advice

Evidence-based practice requires evaluating the source and quality of any clinical claim before acting on it. 'Curing' fibromyalgia is a medical claim beyond the massage therapist's scope of practice. The therapist should assess the evidence critically and refer the client to their physician for medical guidance, while supporting the client's values.
