A RCT has been designed to assess the effectiveness of a balance program on fall risk prevention for an adult population from 75-95 year old. Three groups are compared: a control group that receives a fall risk prevention pamphlet, a group with an exercise protocol of ankle and stepping strategies, and an exercise group of Tai Chi. All patients completed a baseline questionnaire to collect comorbidities as well as fall history and a set of objective tests consisting of the Time Up and Go test (TUG) and the Functional Reach Test (FRT). The TUG was used to screen for risk of falling while the FRT was used to assess changes/improvement in balance. After 4 weeks of the intervention, patients were tested again to measure progression If the assumption of normality is not met, what statistical analysis would you rather choose to compare treatment effectiveness using the FRT?  

The study depicted in the table below wanted to investigate if there were any significant differences in baseline characteristics among all subjects that participated in the study (“participants”), the subset of subjects that completed the six month follow up (“completed) and those who were lost to follow-up (“lost to follow up).   Please carefully review and complete the table below for the variables of “Duration of LBP” and “Radiating pain”: The type of data Based on the type of data the descriptive statistics methods used in the table Assuming all data was found normally distributed. Hypothesize the “inferential” statistic method (statistical analysis) used to assess homogeneity among the three groups Considering

A single blind study indicates that the subjects are unaware of the research hypothesis and the group to which they were assigned.

When reading and appraising the included articles (evidence), what statistical information given in the results/tables would you consider to make your own conclusion regarding the effectiveness of the intervention? (Answer using concepts related to type of expected type statistical analysis and/or magnitude and significance of results)? –Please list and explain TWO specific examples.

A qualitative study of parents and therapists’ perceptions of a high intensity high frequency model of physical therapy for children with cerebral palsy used interviews from five parents, five therapists, and observations of five children with cerebral palsy. Which of the following is true about this method?

A two-tailed test is a test of statistical significance in which deviations from the null hypothesis in either direction is considered.

A group of 100 pre-adolescents without any impairment ages 10 to 12 was recruited into a study to assess risk factors associated to the incidence of neck pain during the high school years. General Health measured by the SF-36 was measured at baseline and every six months for a period of six years. What was the type of study design used?

A. You found a series of 10 of those study designs (from previous answer) and now you need to critically review the articles and create a comparison table. What will be the independent and the dependent variables that you might want to identify in all studies to facilitate comparison?
