chronic ankle instability, Sacroiliac joint dysfunction
Brief summary
chronic ankle instability previously approved in many studies that it may lead to more proximal adaptations and negative long term consequences. one of those studies reported, ankle instability patients has hamstring muscle shortening in comparison with non sprained subjects. another one concluded that gluteus maximums muscle has delayed activation and weakness in CAI patients. Both muscles (hamstring and gluteus Maximus ) contribute to sacroiliac joint stability. therefore, this study asked a novel research question, was sacroiliac joint dysfunction (SIJD) associated with CAI?
Detailed description
The sample size of this study had been calculated based on the primary outcome that was the association between CAI and SIJD after a pilot study done in order to detect odd's ratio. , calculation made by a program developed by the Centers for Disease Control and Prevention with the following inputting data : Two-sided confidence interval 95%, power 80%, ratio of controls to cases 1, percent of control exposed 4.5% , odds ratio 32%. The sample size calculations required for this study was 28 participants (14 in each group). Data distributions was checked for normality using Shapiro-Wilk test and for equality of variance using Box's test. Box and whiskers plots were used for detecting the outliers. Descriptive statistics calculated for demographic data. Intraclass correlation coefficients (ICC) and standard errors of measurement (SEM) were calculated to estimate the intratester reliability and precision of measurement for the static pelvic rotation The outcomes of these study were: 1. Association between CAI and SIJD represents through odd's ratio (primary outcome) 2. Pelvic torsion difference between CAI and control Calculated by Mann- Whitney test (secondary outcome) 3. Correlations between pelvic torsion with perceived ankle instability and number of giving way episodes calculated Pearson correlation coefficient(secondary outcome) Effect size analysis was calculated to determine the clinical significant difference. Statistical analysis was conducted using the statistical package for social studies (SPSS) for windows, version 24 (SPSS, Inc., Chicago, IL). The normative data presented as Mean ± standard deviation (SD) while non-normative data presented as median. Significance was set at p \< 0.05 and total study power was set 80%

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| odd's ratio of sacroiliac joint dysfunction | throughout the study about 1 year | association between CAI and sacroiliac joint dysfunction |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| difference of pelvic torsion between CAI and control | throughout the study about 1 year | pelvic torsion is pelvic asymmetry in sagittal plane |
| correlation between pelvic torsion and giving way episodes | throughout the study about one year | giving way episodes throughout the previous year and pelvic torsion by inclinometer |
| corelation between pelvic torsion and perceived sensation of instability | throughout the study about 1 year | pelvic torsion by inclinometer and perceived instability sensation through visual analogue scale, ranged from 0-10 with high score means worse result |
