Motion Analysis in Sacroiliac Joint Dysfunction (MASSIF)
Motion Analysis Before and After Surgical Sacroiliac Joint Fusion in Patients With Sacroiliac Joint Dysfunction
Rationale: The sacroiliac joint (SIJ) is increasingly being recognized as a potential cause of chronic low back and buttock pain. The SIJ is affected in 14-22% in patients presenting with this pain. Conservative treatment options include oral analgesic use, physical therapy, radiofrequency denervation and intraarticular steroid injections. When non-surgical treatment remains ineffective, surgical intervention is a reasonable option in the form of minimally invasive sacroiliac joint fusion (MISJF). Recent literature suggests that imbalance and sagittal sacropelvic morphology can occur in patients with SIJ dysfunction.
Using motion analyses, the investigators want to evaluate full movement patterns in SIJ patients. Potentially, changes in these parameters can be observed before and after MISJF surgery.
Objective: To determine spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity in patients suffering from SIJ dysfunction before and after MISJF surgery. Movement parameters will also be determined in healthy individuals to compare with patients suffering from SIJ dysfunction.
Methods: This prospective cohort study will include patients enlisted for MISJF surgery because of SIJ dysfunction. Spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity will be examined before and 3 months after surgery in a professional Motion Lab. Movement parameter of healthy individuals will also be evaluated at the Motion Lab. All data will be analyzed using MATLAB software.

Detailed Description
1.2 RATIONALE The sacroiliac joint (SIJ) is an anatomic structure that is increasingly being recognized as a potential cause of chronic low back and buttock pain. The SIJ is affected in 14-22% in patients presenting with this pain.1,2 A wide variability exists in the clinical presentation of SIJ dysfunction, from localized pain around the SIJ to radiating pain into the groin or even the entire lower extremity.3 This sometimes makes it challenging to accurately diagnose SIJ dysfunction during physical examination. Most surgeons palpate the SIJ to determine the level and area of tenderness. There are also several provocative tests, but their reliability is limited.4,5 Currently, diagnostic SIJ intraarticular injection is the benchmark for diagnosing SIJ dysfunction.6 Conservative treatment options include oral analgesic use, physical therapy, radiofrequency denervation and intraarticular steroid injections. 7-11 When non-surgical treatment remains ineffective, minimally invasive sacroiliac joint fusion (MISJF) is a reasonable option.12 Current literature suggests that imbalance and sagittal sacropelvic morphology can occur in patients with SIJ dysfunction.13 Sagittal imbalance and sagittal sacropelvic morphology can in turn lead to compensatory motion in the SIJ, leading to more dysfunction and pain.14 The investigators wonder if changes in spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity can be observed in patients suffering from SIJ dysfunction before and after MISJF surgery with the help of motion analysis. Expectedly, these changes correlate to the clinical condition patients are in
1.3 OBJECTIVES.
This study consists of two different parts, each with different objectives:
Process evaluation on measuring movement patterns in the motion lab:
a. What differences can be detected in spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity between healthy individuals and patients suffering from SI dysfunction?
Clinical evaluation of MISJF surgery in patients with SI dysfunction:
- What differences can be detected in spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity in patients suffering from SI dysfunction before and after MISJF surgery?
- What changes occur in patients suffering from SI dysfunction after MISJF surgery?
2. STUDY DESIGN 2.1 STUDY POPULATION In total 10 patients suffering from SIJ dysfunction with an indication for MISJF, 10 healthy individuals under the age of 25 and 10 healthy individuals matching the demographic characteristics of patients suffering from SI dysfunction will be included. This is a total of 30 individuals.
2.2 INCLUSION CRITERIA
Inclusion criteria for participating clients in the healthy study group:
- Healthy individuals under the age of 25, with no history of SI dysfunction or lower back related illnesses
Inclusion criteria for participating clients in the healthy study group with the same demographic characteristics as the SI dysfunction patients:
- Healthy individuals between the age of 25 and 45, female sex and postpartum with no history of SI dysfunction or lower back related illnesses
Inclusion criteria for the MISJF group:
- The patient is suffering from SIJ dysfunction (uni- or bilateral) because of postpartum pelvic instability or because of Ehlers Danlos syndrome and is enlisted for primary MISJF surgery.
- The patient is mobile enough to perform several tests at the motion lab, needed to obtain spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity.
2.3 EXCLUSION CRITERIA
Exclusion criteria for all participating clients are:
- The individual is not mobile and/or unable to perform tests at the motion lab, needed to obtain spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity.
- Inadequate command of the Dutch language.
Age under 18 years.
3. METHODS This prospective study will examine spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity in healthy individuals and patients suffering from SI dysfunction before and after MISJF surgery.
3.1 STUDY PARAMETERS Spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity are the main study parameters and will be determined in the motion lab when walking (gait analysis) and during single leg stance (both sides). Further tests may include straight leg raise while seated and step-ups (both sides).
3.2 STUDY PROCEDURE First, spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity will be determined in 10 healthy individuals under the age of 25. The same parameters will be determined in 10 healthy individuals matching the demographic characteristics of patients suffering from SI dysfunction (female, aged 25 to 45 years and postpartum). Between these two groups potential differences will be evaluated.
In the second part of the study spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity will be determined in patients suffering from SI dysfunction before MISJF surgery. These patients are elected for primary MISJF surgery for SI dysfunction (uni- or bilateral) because of postpartum pelvic instability or because of Ehlers Danlos syndrome. These data will be compared to that of the healthy study group. Spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity will again be measured in the same patients around 3 months after surgery. The pre- and postoperative outcomes will be analyzed and compared. The data from the healthy individuals will be used as reference data in these analyses.
To limit potential biases, the investigators gather extra information from all subjects of the study. Demographic characteristics will be collected, and questionnaires will be conducted on clinical outcomes using visual analog scale (VAS) for pain, Oswestry Disability Index (ODI) for back function and EQ-5D-3L for health-related quality of life.
With regard to the patients suffering from SI dysfunction some additional data on daily activity will be collected. All these patients will carry an activity monitor/accelerometer for the duration of 1 week before and after surgery to determine activity in these patients. Differences before and after surgery will be analyzed in accordance with the spatiotemporal parameters. Finally, the subjects will be asked to give information about the rehabilitation process and physiotherapy (which program, duration, frequency etc.).
4. SAFETY REPORTING During motion analyses all subjects are "visitors" at the motion lab, a liability insurance is in effect during tests. Instructors/researchers are also covered by this insurance. There is no need for additional insurance.
5. STATISTICAL ANALYSIS Demographic baseline characteristics (e.g. age, ASA classification, gender, affected side) of the study participants will be described as descriptives.
5.1 STUDY PARAMETERS The main study parameters are spatiotemporal parameters, pelvic obliquity, center of gravity and load capacity during motion analysis before and after MISJF surgery for the patients suffering from SI dysfunction. These measurements will be collected at the motion lab and analyzed into data to compare different parameters between group differences (healthy versus SI dysfunction e.g.).
Other outcome parameters are change in questionnaires outcome in pain measured in Visual Analogue Scale (VAS) pain score, disability measured using the Oswestry Disability Index (ODI) and change in quality-adjusted life years (QALY) measured with EQ-5D-3L. Analysis of these PROMs will be achieved by linear mixed models to determine the overall effect over time and difference in change of scores at fixed time points and difference in change from baseline/preoperative. Between group differences of baseline scores will also be determined, including data on the rehabilitation process and physiotherapy.
Activity measured by the activity monitors/accelerometers will be a different outcome parameter. Analysis of the activity data will be achieved to determine overall difference in change of scores 3 months after MISJF surgery from baseline/preoperative.
6. ADMINISTRATIVE ASPECTS Demographic baseline characteristics data collection will be carried out using study management software. To protect the privacy of all participants, all collected data will be encoded. The codes that are related to each individual patient are saved in an excel file, which is locked with a password. Only the principal investigator of the specific site will have access to the encoding keys. The outcome parameters from the motion lab will be saved on the software used at HSZ. Data will be exchanged between HSZ and Zuyderland Medical Center using secured emails.
