Diagnosing sacroiliac joint (SIJ) dysfunction can be tricky. Therapists need to rule out lumbar spine and the hip, and sometimes there is more than one area causing pain and limiting functional mobility. Typically, ruling in SIJ dysfunction is done by pain provocation tests and load transfer tests. Once the SIJ has been ruled in, then therapists can use a variety of treatments. Often those treatments include therapeutic exercise, joint manipulation, and Kinesio tape. But which intervention is the most effective?
A recent study looked at three physical therapy interventions for treatment for SIJ (sacroiliac joint) dysfunction and assessed which was the most effective (Al-Subahi, M 2017). The authors did a systematic review of the literature. The articles were from 2004-2014, written in English, with male and female participants. This review included a variety of experiment types from randomized control trials to case studies. Of the 1114 studies, only 9 met the inclusion and exclusion criteria. Four of the nine studies used manipulation, three used Kinesio Tape, and the three used exercise. One study did both exercise and manipulation, and was looked at in both interventions. All categories had at least one randomized control trial.
For the manipulation intervention, all studies showed a decrease in pain and disability at follow up. The follow ranged from 3 to 4 days to 8 weeks. Disability was measured using the Oswestry Disability Index. One study did manual high velocity and low amplitude thrust manipulation to lumbar and SIJ manipulation and showed improvement with manipulation to SIJ or SIJ and lumbar. The review did not disclose the type of lumbar manipulation, but did state the SIJ manipulation was a side bend and rotation position with an inferior and lateral force to ASIS (anterior superior iliac spine). Another study did either a SIJ manual high velocity and low amplitude thrust manipulation or a mechanical force with manual assistance. One studied did manipulation and home exercises but did not record exercise interventions. The last study did the same SIJ manual high velocity and low amplitude thrust manipulation as in previous study combined with exercise. The exercises are mentioned below.
For the exercise intervention, the studies did primarily stabilization exercises that were either isometric or isotonic eccentric or concentric. Quick PT school review, in isometric exercises the muscle does not change length, while in isotonic eccentric exercises the muscle is being lengthened under load, and isotonic concentric is the muscle shortening under load. All three studies showed decrease in pain. The first study had 7 participants and combined manipulation and exercise. The exercises consisted of 12% max voluntary contraction and eccentric loading quads in supine with hips at 90 degrees, and concentrically loading hamstrings in prone. The second study was a case study and performed 8 lumbo-pelvic-femoral stabilization exercises for 8 weeks. Fun fact: this case study was written by my Therapeutic Exercise teacher in PT school who did a lot of Postural Restoration based exercises. The last study, had 22 participants and educated and provided exercises on deep abdominal and multifidus muscles and do complete these exercises during functional movements throughout the day. These participants were follow up a year later and had decreased pain compared to laser group.
For the Kinesio tape (Kinesio tape) intervention, the studies did not find that Kinesio tape was not an effective intervention, however the follow up ranged from immediately after applying tape to 4 weeks afterwards. In the first study, a randomized controlled trial with 60 participants, the Kinesio tape was applied in sitting with 25% tension of 4 strips making a star pattern over the point of maximal pain. The Kinesio tape was compared to placebo tape and showed equal improvement in pain and disability. The other two studies applied a different taping technique where the Kinesio tape was applied. One applied the tape over erector spinae and internal oblique muscles bilaterally and in the other study the Kinesio tape was applied with 25% tension over external obliques, a second strip was placed from ASIS to PSIS in side-lying, and then a third strip was placed along rectus abdominis muscle. In this same study the tape was applied for weeks (6x/week for 9 hours/day).
In summary, the authors note that all three interventions help decrease pain and disability in women and men with SIJ dysfunction. The authors suggest that manipulation may be the most effective. Kinesio tape showed no significant difference between placebo tape. Exercise was effective, but less so than manipulation.
This review has a lot of limitations. The variety of experiment types with varying degrees of evidence, small number of participants, and lack of blinding. Most studies had a limited follow up ranging from 3-4 days to 12 months. The outcome measures varied greatly. Most studies had pain scores as the outcome measure, though one study only used inclination meter of anterior pelvic tilt. Use of a consistent objective measure in addition to perceived pain and disability would have helped. Only 1 study did pain provocation tests and that study was a case study whose intervention focused on Kinesio-taping.
As physical therapists we want to provide effective evidence-based practice, and we want to provide individualized compassionate care. It is hard to make a direct line between this study’s recommendations and clinical application based on the numerous limitations. I agree with the authors that manipulation and exercise are bread and butter to physical therapists. I disagree about Kinesio tape not being an effective treatment. Is Kinesio tape going to create boney alignment changes? Likely not. Is Kinesio tape (or any other tape) going to give proprioceptive feedback and possibly help calm sensory pathways? Yes. If a patient likes being taped, and thinks it will help, then I will tape them. Even if taping is just placebo effect; it’s still an effect.
