Quantitative Data Results: The study collected quantitative data on the mobility scores of post-stroke patients before and after treatment:

Group A (TherapEase):

Mean Mobility Score before treatment: 42 Mean Mobility Score after 6 weeks of TherapEase: 56 Paired t-test for mobility score improvement: t = 4.87, p < 0.001

Group B (Traditional Therapy):

Mean Mobility Score before treatment: 45 Mean Mobility Score after 6 weeks of traditional therapy: 50 Paired t-test for mobility score improvement: t = 2.31, p = 0.03

Remember:

t-value (t-statistic):

• The t-value represents the magnitude of the difference between the means of the two sets of paired data (e.g., before and after treatment).
• A higher absolute t-value indicates a larger difference between the means.
• The sign of the t-value (positive or negative) indicates the direction of the difference. A positive t-value suggests that the mean of the second measurement is greater than the mean of the first (an increase), while a negative t-value suggests the opposite (a decrease).
• The t-value is used to determine whether the observed difference between the means is statistically significant.

p-value:

• The p-value, often denoted as "p," indicates the probability of obtaining the observed difference (or a more extreme difference) between the means by random chance alone, assuming that there is no true difference.
• A lower p-value suggests stronger evidence against the null hypothesis (the hypothesis that there is no significant difference).
• The conventional significance level (alpha), often set at 0.05 (5%), is used to determine statistical significance. If the p-value is less than alpha (p < 0.05), the results are typically considered statistically significant.

Questions:

1. Interpreting the Data: What do the mean mobility scores for each group before and after treatment suggest about the effects of TherapEase and traditional therapy on mobility in post-stroke patients?

2. Statistical Significance: Is there a statistically significant difference in mean mobility score improvement between the TherapEase and traditional therapy groups? If so, what does this indicate?

3. Clinical Significance: How would you interpret the clinical significance of the observed mobility score changes in both groups? Is the observed improvement in mobility clinically meaningful for post-stroke patients?

4. Implications for Practice: Based on the study results, how might these findings influence the choice of rehabilitation methods for post-stroke patients in your practice setting?
