  • Objective: This study aimed to determine the effect of proprioceptive neuromuscular facilitation (PNF) balance exercise on the ability to balance and walk in patients with hemiplegia caused by stroke. Design: A randomized controlled trial Methods: Following baseline measurements, patients (n=24) with hemiplegia caused by stroke were randomized into two groups: the PNF balance group (n=12) that received PNF balance exercise and the balance group (n=12) that received general balance exercise. Each group joined the intervention for 30 minutes, 5 times per week for 6 weeks. Both groups performed the Timed Up and Go test (TUG) and Berg Balance Scale (BBS) for balance, as well as the 10-meter walking test (10MWT) and 6-minute walk test (6MWT) for walking. The data were collected both before and after the intervention. The paired t-test was used to compare the post-intervention changes compared with pre-intervention data. An independent t-test was used to analyze the differences in the dependent variables between the two groups. Results: After the 6-week intervention, both groups showed significant improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) parameters (p<0.05). The patients in the PNF balance group showed greater improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) than those in the balance group (p<0.05). Conclusions: PNF balance exercise shows improvements in balance and walking parameters in patients with hemiplegia caused by stroke.

  • Objective: We aimed to identify the effects of proprioceptive neuromuscular facilitation (PNF) stretching on pain, hip range of motion, and functional disability in patients with chronic low back pain. Design: Randomized controlled trial Methods: In total, 45 patients with chronic low back pain were randomly divided into a conventional stretching group (n=22) and a PNF stretching group (n=23). Both interventions were performed three times per week for 6 weeks. Assessments were made using the visual analog scale, Flexion-Abduction-External Rotation test, modified Thomas test, prone hip extension test, and Oswestry disability index before and after the 6-week intervention period. We conducted a paired t-test to compare the within-group findings before and after the intervention. An independent t-test was used to compare the between-group differences. The statistical significance level was set at α=0.05, for all variables. Results: Both groups showed significant improvements in pain, hip range of motion, and functional disability after the intervention (p<0.05). A significant difference was observed in pain, hip range of motion, and functional disability in patients belonging to the PNF stretching group (p<0.05). Conclusions: This study provides evidence that the application of PNF stretching can effectively reduce pain and improve hip range of motion and functional disability in patients with chronic low back pain.

  • Purpose - This study focused on the attitude differences towards harmony-focused Ad and uniqueness-focused Ad, also those towards brand advertised in each of the two type Ads between self-construals. Research design, data, and methodology - Main survey was conducted online with the people in China, and collected 107 data through harmony Ad questionnaire and 109 data through uniqueness Ad questionnaire. Anova and t-test were used to verify hypotheses. Results - First, More positive attitude towards harmony-focused Ad and the brand in it there was at interdependent Chinese consumers than at independent Chinese consumers. Second, the independent Chinese consumers and the interdependent Chinese consumers did not form significant attitude difference towards uniqueness-focused Ad. However the independent Chinese consumers showed more positive attitude towards the brand in the uniqueness-focused Ad than the interdependent Chinese consumers. Conclusions - By highlighting the attributes of Chinese consumers' self-construal, to appeal to interdependent Chinese consumers, marketers should develop harmony-focused advertisement, and they should appeal to independent Chinese consumers by using uniqueness-focused advertisement. However the harmony might be pursued as the main content in the overall environment by Chinese people. Therefore it is necessary for the marketers to consider the harmony even when appealing them by emphasizing the uniqueness.

  • Sample size determination is critical, but not easy to do. Sample size defined as the number of observations in a sample to be studied should be big enough to have a high likelihood of detecting a true difference between groups. Practical procedure for determining sample size, using $G^*$power and previous dental articles, was shown in this study. Examples involving independent t-test, paired t-test, one-way analysis of variance(ANOVA), and one-way repeated-measures(RM) ANOVA were used. The purpose of this study is to enable researchers with non-statistical backgrounds to use in practice freely available statistical software G*power to determine sample size and power.
