To investigate trends of the research designs and statistical methods in the
The authors reviewed all articles published in ARM and APMR for the years 2005 and 2015 in order to determine their research designs as well as their statistical methods used in each article.
In ARM, randomized controlled trials increased from 4.5% in 2005 to 6.5% in 2015. In APMR, randomized controlled trials increased from 8.1% in 2005 to 14.0% in 2015, meta-analyses increased to 5.3%, and systematic reviews increased to 6%. The number of studies using statistical methods increased in ARM from 1.9 to 2.6 per article and in APMR, from 2.7 to 3.1. Use of advanced methods in ARM also showed an increase from 2005 to 2015.
This study concludes that there is a trend of increased awareness and attempts to use varied research approaches in ARM articles. There should also be more in-depth discussions and opportunities for researchers to share their experiences regarding statistical methods in the clinical field.

Objective: The purposes of this study are to find out the characteristics of patients with pain in outpatient practice of rehabilitation medicine and to provide basic data for outpatient management.
Method: We surveyed a hundred one outpatient practices with questionnaire including the distribution of diagnosis, pain site, disease related with pain, pain treatment method, etc.
Results: 1) Distribution of diagnosis was traumatic brain injury (TBI) 10.5%, stroke 14.8%, spinal cord injury (SCI) 10.8%, musculoskeletal disorder (MSD) 55.8% and others 8.1% in training hospital, and TBI 6.7%, stroke 10.6%, SCI 14.0%, MSD 58.7% and others 10.0% in non-training general hospital, and TBI 2.6%, stroke 4.9%, SCI 2.9%, MSD 78.3% and others 11.3% in private clinic. 2) The most common site of pain was low back area. 3) The most common disease related with pain was myofascial pain syndrome. 4) Trigger point injection and physical therapy were performed for pain treatment in most of outpatient practice, whereas local injection and nerve block were less used.
Conclusion: We believe that this study's results will provide helpful basic-data for management of outpatient with pain.
Statistical methods are widely used for the analysis of data obtained from experimental or observational studies. We examined the statistical methods used for papers published in the Journal of Korean Academy of Rehabilitation Medicine in 1996. The issues included the mean, coefficient of variation, t-test, chi-square test, ANOVA and type IV error. The mean and the standard deviation in descriptive statistics and the t-test in inferential statistics were most frequently used. Statistical methods should incorporate statistical modelling and the needed assumptions. Trials of new statistical models and methods are recommended.
