Mechanical Diagnosis and Therapy approach to assessment and treatment of derangement of the sacro-iliac joint

Self-Treatment of Chronic Low Back Pain Based on a Rapid and Objective Sacroiliac Asymmetry Test: A Pilot Study

BACKGROUND

Low back pain (LBP) is common, costly, and disabling. This study assesses a novel and simple LBP evaluation method and its merit in guiding the direction of a self-treatment exercise.

METHODS

Randomized open-label intention is used to treat the study. Consecutive patients with LBP ≥ three months and pain ≥ 5/10 were evaluated in a Vancouver clinic with the sacroiliac forward flexion test (SIFFT) by comparing the height of posterior superior iliac spines using a level. Those with asymmetry ≥ 5 mm were offered participation. The assistant, who generated and encrypted the randomization, assigned participants: group 1 learned a two-minute, SIFFT-derived, sacroiliac-leveling exercise (SIFFT-E) as needed for LBP relief; group 2 used a pelvic stabilization belt as needed to prevent LBP, and group 3 continued the usual care. After one month, all participants used SIFFT-E and belt as needed for one month. The identifier number of this article in Clinicaltrials.gov is #NCT03888235. The trial is closed. Our primary outcome measure was the Oswestry disability index (ODI) (decrease) from baseline to one and two months. We also followed SIFFT improvement (decrease).

FINDINGS

Of 72 LBP patients, 62 (86%) had ≥ 5 mm asymmetry. From zero to one month, the 21 (one dropout) SIFFT-E participants outperformed the 20 usual care participants for ODI improvement (12.5 ± 14.8 vs. -3.4 ± 14.9 points; mean difference 15.9 [CI 6.7-25.0]; P = 0.002 with number needed to treat (NNT) of 3.0 for ODI improvement ≥ 11). Belt use results were intermediate. At two months, after all the 62 participants used the exercise and belt as needed, combined ODI improvements were clinically significant (12.0 ± 18.4 points), and SIFFT asymmetry was reduced by 8.6 ± 8.6 mm. Five (8%) exercise and 12 (19%) belt wearers experienced mild side effects.

INTERPRETATION

Sacroiliac asymmetry appears to be frequent. SIFFT may be clinically useful as an evaluation tool for prescribing a simple self-directed corrective exercise as seen by clinically significant improvements in function and asymmetry.

Short-term effect of muscle energy technique and mechanical diagnosis and therapy in sacroiliac joint dysfunction: A pilot randomized clinical trial

INTRODUCTION

Sacroiliac joint dysfunction (SIJD) is a prominent source of pain in low back pain (LBP) patients. Tenderness inferior to the posterior superior iliac spine (PSIS) is an important sign presented in SIJD. Techniques including muscle energy technique (MET) and mechanical diagnosis and therapy (MDT) have shown benefits in SIJD. However, the effects of these treatments on tenderness and pain around the PSIS are yet to be determined.

AIM

Compare and examine the preliminary short-term effect of MET and MDT on tenderness and pain around the PSIS in SIJD.

METHODS

Twenty patients, aged between 20 and 65 years and diagnosed with unilateral, sub-acute, or chronic SIJD, were screened for the inclusion criteria and were randomly allocated to the MET or the MDT group. Both the groups received treatment for four sessions over one week. Pain pressure threshold (PPT) and visual analogue scale (VAS) were determined by a blinded assessor on pre- and post-treatment basis.

RESULTS

Although no significant differences were observed following the treatment between the groups, some statistically significant (p < 0.05) improvements were observed within each of the groups. No drop-outs and no adverse events were reported.

CONCLUSION

The findings of the study suggest that both interventions may be equally effective in reducing symptoms around the PSIS. However, due to the small sample size, the results need to be interpreted cautiously. Future studies on larger sample size and long-term follow up are warranted.

The impact of progressive pelvic floor muscle exercise and manual therapy in a patient postpartum who met the criteria for sacroiliac joint pain based on Laslett's cluster of provocation signs

Sacroiliac joint (SIJ) pain has been identified as a primary or contributing source of pain in patients with low back pain. The Laslett cluster of SIJ pain provocation tests has the strongest evidence for noninvasive clinical testing. The purpose of this report was to describe the impact of physical therapy treatments for a patient postpartum with SIJ pain who satisfied the Laslett cluster. Specifically, the goal was to assess the impact of progressive pelvic floor muscle exercise and manual therapy. The Modified Oswestry Low Back Pain Disability Questionnaire (MODI) was the primary outcome measure used in this case. In addition, the Numeric Pain Rating Scale (NRPS) and Global Rating of Change (GROC) were used as secondary outcome measures. In this case report, the patient responded to the combined interventions with decreases in MODI, NRPS and GROC. Further research is warranted to develop stronger evidence to identify specific interventions for the treatment of SIJ pain.

Treatment of shoulder pain utilizing mechanical diagnosis and therapy principles

This case report describes the effectiveness of mechanical diagnosis and therapy (MDT) in the management of a patient referred with a diagnosis of shoulder tendonitis. The patient was a 56-year-old male with a 3-month history of left anterior shoulder pain. Upon initial assessment, he presented with a positive open-can test, lift-off test, and Hawkins-Kennedy impingement test. A MDT assessment quickly ruled out cervical involvement and identified a loss of end-range shoulder mobility and pain during active shoulder movement. After the patient underwent a repeated movement examination and treatment based on responses to end-range movements over three visits, his shoulder pain was abolished and motion was fully restored. Despite having positive rotator cuff and impingement signs, this patient was effectively treated with repeated end-range movements over a short period of 2 weeks. This case demonstrates that treatment based on MDT sub-classification principles may be an effective way to manage shoulder pain as it is in the spine.

Serum tumour markers as a diagnostic and prognostic tool in Libyan breast cancer

Results from studies on efficacy of carcinoembryonic antigen (CEA), carbohydrate antigen 15.3 (CA 15.3) and thymidine kinase (TK1) as diagnostic and prognostic tools for primary breast cancer (BC) have presented conflicting results, and usefulness of these markers for clinical use in BC remains unclear. The aim of this study is to evaluate potential of concentration of the sera CEA, CA15.3 and TK1 peptides' use as markers in the diagnosis and prognosis of breast lesions of Libyan patients. Serum tumour markers were studied in 20 healthy subjects, 30 patient with benign lesion diseases and 50 patients with histologically confirmed BC diagnosed at the National Cancer Institute (NCI), Misurata, Libya during the period 2005-2009. The concentrations of the BC patients' cutoff points used for diagnostic and prognostic sensitivity were 8.82 ng/ml, 35.57 U/ml and 32.57 U/mg/protein for CEA, CA15.3 and TK1, respectively. Increased CEA (>8.82 ng/ml), CA 15.3 (>35.57 U/ml) and TK1 (>32.57 U/mg/protein) concentrations were found in 62 %, 70 % and 78 % of the BC patients, respectively. For all three tumour markers, increased concentrations correlated increased tumour size and nodal involvement. Significantly higher serum TK1 levels were found in patients with advanced disease (p < 0.0001) and TK1 levels also correlated with disease-specific survival (DSS, p < 0.07). The combined data set of the three markers' data from three markers increased the diagnostic sensitivity to 90 %. The serum marker analysis for CEA, CA 15.3, and S-TK1 concentrations is shown to be a useful tool for identification of malignant cases in our BC population and for the prognostic evaluation of patients with primary BC. Increased concentrations of the markers were also observed to be higher in patients with advanced tumours and indicative of the development of distant metastasis.

Chiropractic management of chronic idiopathic meralgia paresthetica: a case study

OBJECTIVES

This report describes the case of a patient with chronic idiopathic meralgia paresthetica associated with bilateral sacroiliac joint dysfunction who was managed with chiropractic care.

CLINICAL FEATURES

A 35-year-old white woman presented to a private chiropractic clinic with a complaint of numbness in the right anterolateral thigh region. Neurological assessment revealed a diminution of sensibility and discrimination on the right lateral femoral cutaneous nerve territory. Pain was rated as 8.5 on a numeric pain scale of 0 to 10. Musculoskeletal examination of the pelvic region disclosed bilateral sacroiliac joint dysfunction.

INTERVENTION AND OUTCOMES

Chiropractic management included pelvic mobilizations, myofascial therapy, transverse friction massage, and stretching exercises. After 3 visits (2 weeks later), result of neurological evaluation was normal, with no residual numbness over the lateral thigh.

CONCLUSION

In the present case, chiropractic management with standard and applied kinesiology techniques resulted in recovery of meralgia paresthetica symptoms for this patient.

Evidence-based diagnosis and treatment of the painful sacroiliac joint

Sacroiliac joint (SIJ) pain refers to the pain arising from the SIJ joint structures. SIJ dysfunction generally refers to aberrant position or movement of SIJ structures that may or may not result in pain. This paper aims to clarify the difference between these clinical concepts and present current available evidence regarding diagnosis and treatment of SIJ disorders. Tests for SIJ dysfunction generally have poor inter-examiner reliability. A reference standard for SIJ dysfunction is not readily available, so validity of the tests for this disorder is unknown. Tests that stress the SIJ in order to provoke familiar pain have acceptable inter-examiner reliability and have clinically useful validity against an acceptable reference standard. It is unknown if provocation tests can reliably identify extra-articular SIJ sources of pain. Three or more positive pain provocation SIJ tests have sensitivity and specificity of 91% and 78%, respectively. Specificity of three or more positive tests increases to 87% in patients whose symptoms cannot be made to move towards the spinal midline, i.e., centralize. In chronic back pain populations, patients who have three or more positive provocation SIJ tests and whose symptoms cannot be made to centralize have a probability of having SIJ pain of 77%, and in pregnant populations with back pain, a probability of 89%. This combination of test findings could be used in research to evaluate the efficacy of specific treatments for SIJ pain. Treatments most likely to be effective are specific lumbopelvic stabilization training and injections of corticosteroid into the intra-articular space.

Conservative management of a young adult with hip arthrosis

STUDY DESIGN

Case report.

BACKGROUND

Clinical practice guidelines regarding the conservative management of degenerative hip conditions in older adults routinely incorporate therapeutic exercise and manual therapy. However, the application of these recommendations to young, active adults is less clear. The purpose of this case report is to describe the management of a young adult with advanced hip arthrosis using a multifaceted rehabilitation program.

CASE DESCRIPTION

A 28-year-old female with severe left hip degeneration, as identified with diagnostic imaging, was referred to physical therapy. Reduced hip range of motion and strength, sacroiliac joint asymmetries, and a modified Harris Hip Score of 76 were observed. She was seen for 12 visits over a 3-month period and treated with an individualized program including manual therapy, therapeutic exercise, and neuromuscular re-education.

OUTCOME

Substantial improvements were noted in pain, hip range of motion, and strength and function (modified Harris Hip Score of 97). In addition, she discontinued the use of anti-inflammatory medications and returned to her prior level of activity. Improvements were maintained at a 3-month follow-up, with symptom recurrence managed using a self-mobilization technique to the left hip and massage to the left iliopsoas.

DISCUSSION

Degenerative hip conditions are common among older adults but are relatively rare in the younger population. Although it is likely that this patient will experience a return of her symptoms and functional limitations as her hip disease progresses, the immediate improvements may delay the need for eventual surgical management. These outcomes suggest that physical therapy management should be considered in those with an early onset of degenerative hip disease and are consistent with results previously reported in the older population.

LEVEL OF EVIDENCE

Therapy, level 4.
