Study Protocol 
 
Thirty subjects will be recruited using convenient sampling from the university 
community through word of mouth including email communications. The inclusion 
criteria are male or female, age 18 to 65, with all 4 extremities intact, and ability to stand 
still for 20 seconds. The exclusion criteria are unable to stand with their feet together or 
one foot apart for at least 20 seconds, unable to wrap their arms around their torso or 
keep their hands on their hips for 20 seconds, unable to perform sit to stand transfer 
and ambulation independently, and cognitive impairments that interfere with the 
experimental procedures.  
The willingness of the subjects’ participation and subjects’ right to refuse participation 
will be fully explained and documented in the informed consent form. Demographical 
information (age and gender) will be collected.  
The research design is a randomized controlled trial. Subjects will be randomly 
assigned to the experimental group or the control group. In the experimental group, 
subjects will stand with hands on their hips, elbows pointing out and feet approximately 
one foot apart (high-power) for 20 seconds. In the control group, subjects will stand with 
hands and arms wrapping around the torso and feet together (low-power) for 20 
seconds.  
Outcome measurement includes TUG test. The outcome measurements will be prior to 
the postural intervention to establish a baseline and immediately after the postural 
intervention to detect any changes.  
Data Analysis 
Changes in TUG test scores will be reported as mean and standard deviation (SD). 
Student t-test will be used to determine whether there were statistically significant 
differences between the changes in the outcome measurements in the HP and LP 
groups. An alpha value of 0.05 will be used to determine statistical significance.
