Effectiveness of focused extracorporeal shock wave versus manual therapy in postpartum patients with sacroiliac joint dysfunction: a prospective clinical trial.

OBJECTIVE: To investigate the effectiveness of focused extracorporeal shock wave therapy (FESWT) in treating postpartum sacroiliac joint (SIJ) dysfunction. METHODS: A total of 90 patients with SIJ dysfunction were included and randomly assigned to FESWT, manual therapy (MT), or combination therapy (CT) groups. Pain intensity and Oswestry Disability Index (ODI) score were measured upon admission, after 1 and 2 weeks of treatments. The treatment efficacy and adverse events of each group were also assessed. RESULTS: There were no significant differences among three groups regarding clinical data, pain intensity, and ODI score on admission (all P > 0.05). After 1 week of treatment, FESWT exhibited similar pain intensity and lower ODI score (P < 0.001) compared to MT. After 2 weeks of treatment, the pain and ODI in FESWT were similar with MT. The pain in CT was lower than MT after 1 week, but lower than FESWT after 2 weeks. Furthermore, we identified interaction effects between treatment method and duration in relation to pain intensity (Fgroup*time = 5.352, P = 0.001) and ODI score (Fgroup*time = 5.902, P < 0.001). FESWT group exhibited the highest improvement rate of 66.7%, while CT group achieved the highest cure rate of 73.3%. No adverse events were observed in any of the patients during 2 months follow-up period. CONCLUSIONS: Compared to MT, FESWT mainly reduced the ODI score rather than pain after 1 week of treatment. After 2 weeks, the effect of FESWT in relieving the pain was inferior to the MT.

Effect of medical choice and health behavior on the health status for patients with subluxation of the sacroiliac joint.

The sacroiliac joint is an important part of human life behavior and daily activities. With the increase in people's lives and work pressure and the change of travel mode, the incidence rate of sacroiliac joint subluxation is getting higher and higher. The purpose of this study is to explore the relationship between medical choice, health behavior, and health status of patients with sacroiliac joint subluxation and put forward feasible suggestions for promoting the treatment and rehabilitation of patients. The EuroQoL 5 Dimensions 5 Levels health index survey scale was selected to investigate the health status of patients with sacroiliac joint subluxation. T test and analysis of variance were used for univariate analysis of medical choice and health behavior of patients with sacroiliac subluxation, and ordinary least squares was used for multivariate analysis. The elderly patients with subluxation of sacroiliac joint are in poor health. The health status of patients who chose to seek medical treatment for disease diagnosis and prescription was significantly worse. Patients with subluxation of sacroiliac joint with regular defecation have better health status. Patients who travel by bike or bus have worse health. The health status of those who sit still for more than 1 hour a day is significantly better. The health status of patients with sacroiliac subluxation is closely related to their choice of medical treatment and health behavior. It is suggested that rehabilitation therapy such as acupuncture and manipulation should be selected for intervention. Good health behaviors such as abstinence and regular defecation should be shaped. More attention should be paid to the health status of women at risk.

[Effect on ankylosing spondylitis at early-middle stage and bone marrow edema of sacroiliac joint treated with acupuncture and governor vessel moxibustion].

OBJECTIVE: To observe the efficacy of the combined treatment with acupuncture and governor vessel moxibustion on ankylosing spondylitis (AS) at early-middle stage and investigate the effect on bone marrow edema of sacroiliac joint. METHODS: Seventy patients of AS at early-middle stage were randomized into an observation group (35 cases) and a control group (35 cases, 1 case dropped off ). In the control group, the recombinant human tumor necrosis factor receptor-antibody of type Ⅱ fusion protein for injection was injected subcutaneously, 25 mg each time, once on every Monday and Friday, consecutively for 3 weeks. In the observation group, on the base of the intervention as the control group, acupuncture combined with governor vessel moxibustion were provided. Acupuncture was applied to Dazhui (GV 14), Changqiang (GV 1), Zhibian (BL 54), Baihui (GV 20), etc.; the thermal needling technique was adopted at Dazhui (GV 4) and Changqiang (GV 1) for promoting the circulation of the governor vessel, and the ginger-isolated moxibustion on the governor vessel was combined. Such intervention measure was provided once daily. One treatment session contained 7 treatments and 3 sessions were required. Before and after treatment, the scores of Spondyloarthritis Research Consortium of Canada (SPARCC), Bath ankylosing spondylitis disease activity index (BASDAI) and Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis patient global score (BAS-G) were observed in the two groups separately. The efficacy and adverse effects were assessed in the two groups after treatment. RESULTS: The scores of SPARCC, BASDAI, BASFI and BAS-G were all reduced after treatment compared with those before treatment in the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 82.4% (28/34) in the control group (P<0.05). There were 4 cases of gastrointestinal reactions and 1 case of skin rashes in the control group; and 3 cases of local skin redness and pruritus after governor vessel moxibustion, no any drug adverse effect was found in the observation group. CONCLUSION: Based on the western medicine treatment, the combined therapy of acupuncture and governor vessel moxibustion may relieve bone marrow edema of sacroiliac joint in patients with AS at early-middle stage, control the progression of disease and improve the daily life activity. This therapy is relatively safe and effective.

Effect of osteopathic manipulation of the sacroiliac joint vs electrotherapy on pain and functional disability in patients with low back pain: A pilot study.

BACKGROUND: One of the main problems faced by physiotherapists in primary care is low back pain with or without radiation to lower limbs. There are many different treatment approaches for the management of low back pain. Despite the large amount of published studies, the evidence remains contradictory. OBJECTIVE: To evaluate the influence of the osteopathic manipulation of the sacroiliac joint on low back pain with or without radiation to lower limbs. METHOD: Single-blind randomized clinical controlled trial. Participants with low back pain with or without lower limb radiation were randomized to osteopathic manipulation of the sacroiliac joint group (intervention, 6 sessions) or to an electrotherapy group (control, 15 sessions) for 3 weeks. Measures were taken at baseline (week 0) and post-intervention (week 4). The primary outcome measures were pain (Visual Analogue Scale), functional disability (Oswestry disability index and Roland Morris questionnaire). The secondary outcome measure was pain threshold at muscular tender points in the quadratus lumborum, pyramidal, mayor gluteus, and hamstrings. RESULTS: In all, 37 participants completed the study. The results of the intragroup comparisons showed statistically significant improvements in both groups in the visual analogue scale (Osteopathic manipulation group, P= 0.000; Electrotherapy group, P= 0.005) and Oswestry disability index (Osteopathic manipulation group, P= 0.000; Electrotherapy group- P= 0.026) but not in the Roland Morris questionnaire (P= 0.121), which only improved in the intervention group (P= 0.01). The osteopathic manipulation was much more effective than electrotherapy improving to pain and functional disability. CONCLUSION: Osteopathic manipulation of the sacroiliac joint improves pain and disability in patients with sacroiliac dysfunction after three weeks of treatment.

Osteopathic approach to sacroiliac joint pain in pregnant patients.

This paper aims to provide a comprehensive review of the management of sacroiliac (SI) joint pain in pregnant patients. Although SI joint pain is highly prevalent among pregnant patients, the unique anatomy of the joint is rarely discussed in a clinical setting. This paper provides comprehensive review of the epidemiology, anatomy, alarm findings, standard treatment, osteopathic assessment, and osteopathic manipulative treatment (OMT) of the SI joint, and it provides a general and in-depth understanding of the SI joint pain in pregnant patients and its management.

Comparison of Efficacy between Acupuncture Therapies in Improving Sacroiliac Joint Malposition: A Systematic Review and Meta-Analysis.

AIM: To provide available quantitative evidence of efficacy and safety of acupuncture treatments for improving sacroiliac joint malposition. METHODS: Databases such as the China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (CQVIP), Wanfang Database (Wanfang), China Biology Medicine disc (CBMdisc), PubMed, Web of Science, EMBASE, and Cochrane Library were searched by computer to collect the reports on acupuncture treatment of sacroiliac joint malposition from the database creation to July 20, 2021. The selection of included studies, data extraction and coding, and bias risk assessment were conducted independently by two reviewers. RevMan5.4 software was used for meta-analysis, and the results were expressed as mean difference (MD) or standardized mean difference (SMD), with a confidence interval (CI) of 95%. RESULTS: A total of 10 randomized controlled clinical trials (RCTs) with 1019 participants were included. Their overall quality of methodology was not high, and there may be publication bias. Meta-analysis showed that the total effective rate of the treatment group was higher than that of the control group (OR = 2.74, 95% CI 2.00 to 3.74, P < 0.00001). The treatment group was better than the control group in improving VAS score (WMD = -1.56, 95% CI -2.18 to -0.94, P < 0.00001). The ODI score of the treatment group was lower than that of the control group (WMD = -6.04, 95% CI -7.05 to -5.02, P < 0.00001). With the improvement of the JOA score, the difference of iliac transverse diameter of sacroiliac joint dislocation and the index of sacroiliac joint malposition in the treatment group were better than those in the control group (P < 0.05). There was no significant heterogeneity among the studies. CONCLUSION: Acupuncture may have therapeutic advantages in improving sacroiliac joint malposition. Acupuncture and acupotomy provide a safe way to improve the related clinical symptoms and functional disorders in activity of sacroiliac joint dislocation. However, due to the low quality of the included literature, this conclusion still needs to be further verified by more high-quality and large-sample RCTs.

Effects of mobilization treatment on sacroiliac joint dysfunction syndrome.

OBJECTIVE: This study aims to reveal the short-term effects of exercise therapy and manual therapy plus exercise therapy on pain, quality of life, and physical examination results in the treatment of sacroiliac joint dysfunction syndrome (SIJDS). METHODS: In this study, 64 patients who were participated were divided into two groups. The first group (exercise group) was assigned with the sacroiliac joint (SIJ) home exercise program and the second group (mobilization group) with the combined SIJ manual therapy and home exercise program. Physical examination tests, visual analog scale, and SF-36 evaluation were performed at the beginning of the study, at 24 h, at 1 week, and 1 month after the treatment. RESULTS: Both groups showed that the rate of pain in the posttreatment, after the first week, and the first month; the presence of pain in the sacroiliac region; and VAS values of the patients with SIJDS compared to pretreatment values were clearly decreased (p<0.05). All tests performed in the SIJ physical examination showed significant improvement within both groups (p<0.05). However, there was no statistical difference between the two groups in 1-month period (p>0.05). CONCLUSIONS: We found that the home exercise program and the manual therapy plus exercise program significantly improved pain intensity, quality of life, and the findings of specific tests in patients with SIJDS. In addition, superiority between the two groups in terms of pain intensity, quality of life, and specific tests was not determined.

The Influence of Sacroiliac Joint Manipulation on Changes in the Values of the Center of Pressure in the Process of Maintaining Static Body Balance.

OBJECTIVE: The aim of the study was to determine the influence of manipulative treatment of sacroiliac joint (SIJ) hypomobility on the ability to maintain static balance of the body. METHODS: We compared displacements of the center of pressure (COP) in 2 groups of students of the University of Physical Education: the experimental group (30 people exhibiting SIJ hypomobility) and the control group (29 people without SIJ hypomobility). A manipulation was performed in the experimental group and a placebo procedure in the control group. Sacroiliac joint hypomobility was diagnosed by the following SIJ mobility tests: forward flexion test, Gillet test, long sitting test, lower limb adduction test. These and podometric tests were performed on all participants twice-before and after the procedure. The influence of experimental manipulation was examined by applying repeated-measures analysis of variance, and comparisons were made with Student's t test for dependent and independent samples and nonparametric tests. RESULTS: A statistically significant difference between before and after treatment was found in the experimental group (P < .05) in terms of COP pathway, COP pathway area, and average COP speed. Furthermore, the groups differed in before-treatment values of these parameters in favor of the control group, but after-treatment measurement revealed normalization of the levels of these characteristics in the experimental group to the level of the control group. CONCLUSION: As a result of SIJ manipulation, parameters related to the ability to maintain balance improved in the experimental group.

Diagnostic Accuracy of Clusters of Pain Provocation Tests for Detecting Sacroiliac Joint Pain: Systematic Review With Meta-analysis.

OBJECTIVE: To assess the diagnostic test accuracy of pain provocation tests for the sacroiliac joint. DESIGN: Systematic review of diagnostic test accuracy. LITERATURE SEARCH: Seven electronic databases and reference lists of included studies and previous reviews were searched. STUDY SELECTION CRITERIA: Studies investigating the diagnostic accuracy of clusters of clinical tests for sacroiliac joint pain were included. DATA SYNTHESIS: Bivariate random-effects meta-analysis was employed. Risk of bias and applicability concerns were assessed using the revised Quality Assessment of Diagnostic Accuracy Studies tool, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool was used to judge credibility of evidence. RESULTS: From 2195 records identified in the search, 5 studies were included that assessed clusters of pain provocation tests for the sacroiliac joint. The estimated positive likelihood ratio was 2.13 (95% confidence interval [CI]: 1.2, 3.9), the negative likelihood ratio was 0.33 (95% CI: 0.11, 0.72), and the diagnostic odds ratio was 9.01 (95% CI: 1.72, 28.4). The GRADE ratings for the outcomes were of very low certainty. Assuming a point prevalence of sacroiliac joint pain of 20%, we calculated a positive posterior probability of 35% (95% CI: 32%, 37%) and negative posterior probability of 8% (95% CI: 6%, 10%). CONCLUSION: A positive result on a sacroiliac joint pain provocation test cluster gives the clinician 35% certainty of having correctly identified sacroiliac joint pain. Clusters of pain provocation tests for the sacroiliac joint do not provide sufficient diagnostic accuracy for ruling in the sacroiliac joint as the source of pain. Clinicians can rule out the sacroiliac joint as the source of pain with more confidence: the negative posttest probability indicates that the clinician can conclude with 92% certainty that a negative test result is correct.

The Efficiency of Manual Therapy and Sacroiliac and Lumbar Exercises in Patients with Sacroiliac Joint Dysfunction Syndrome.

BACKGROUND: Manual therapy, exercise therapy, and the combination of these 2 are common treatments for sacroiliac joint dysfunction syndrome. The effects of these treatments have been discussed in several studies; the superiority of one over the other for patients with sacroiliac joint dysfunction syndrome is still the subject of discussion. OBJECTIVE: This study aims to assess the effects of manual therapy for sacroiliac joints, sacroiliac joints home-based exercises, and home-based lumbar exercises. STUDY DESIGN: A comparative, prospective, single-blind, randomized, controlled trial. SETTING: This trial was conducted at a single center at the Istanbul University, Istanbul Medical Faculty, Department of Physical Medicine and Rehabilitation. METHODS: Within the scope of this study, 69 women diagnosed with sacroiliac joint dysfunction syndrome through specific sacroiliac joints clinical diagnostic tests were randomized into 3 groups. The first group was assigned manual therapy and a sacroiliac joints home-based exercise program (n = 23), the second group was assigned sacroiliac joints manual therapy and a home-based lumbar exercise program (n = 23), and the third group was assigned a home-based lumbar exercise program (n = 23). All patients who participated in the study were evaluated at the beginning of the study and on the twenty-eighth and ninetieth day. RESULTS: All 3 groups showed a significant decrease in the sacroiliac joints -related pain parameter, which is checked with the visual analogue scale (P < 0.05) after the treatment. The Gillet test, Vorlauf test, Posterior Shear test, Compression test, and irritation Point tests after the treatment yielded a significant (P < 0.05) negative trend in all groups. Short Form-36 health survey for screening form, Modified Oswestry Pain Questionnaire, and Douleur Neuropathique 4 questions patient interview questionnaire for the assessment of neuropathic pain forms revealed a significant (P < 0.05) improvement in patients' complaints after the treatment in all 3 groups. Significant improvement in patients with sacroiliac joint dysfunction syndrome in all 3 groups was identified after the treatment. LIMITATION: The absence of a healthy control group is one of the important limitations of the study. CONCLUSIONS: Manual therapy is effective in the long term in sacroiliac joint dysfunction syndrome. Adding specific exercises for sacroiliac joints to the sacroiliac joints manipulation treatment further increases this effectiveness.

Validity and Reliability of Palpatory Clinical Tests of Sacroiliac Joint Mobility: A Systematic Review and Meta-analysis.

OBJECTIVE: The primary objective of this review was to investigate the reliability and validity of palpatory clinical tests of sacroiliac mobility. The secondary objective was to investigate which palpatory clinical tests of sacroiliac mobility exist in the literature. METHODS: PubMed, Embase, Scopus, Medline, and the Physiotherapy Evidence Database were searched. There was no restriction on the study design or participants. The data extracted from each study were sample size, study deign, and clinical test used. If there was information on reliability values, number of examiners, concurrent validity values, gold standard used, or inferential statistical test used, that was also extracted. For intraexaminer reliability, the data were expressed as κ values that were meta-analyzed using random effects. RESULTS: Fifteen palpatory clinical tests of sacroiliac mobility were identified from 28 studies; 14 studies performed inferential statistical analysis, all including analysis of interexaminer reliability, with κ values ranging from -0.05 to 0.77. Analysis of intraexaminer reliability was performed in 8 studies, with κ values ranging from 0.08 to 0.73. No study included in this systematic review verified the concurrent validity of the tests. Our meta-analysis of intraexaminer reliability showed moderate to good agreement results for the Gillet test (κ = 0.46), the standing flexion test (κ = 0.61), and the sitting flexion test (κ = 0.68). CONCLUSION: We found 15 palpatory clinical tests of sacroiliac mobility in this systematic review. According to our meta-analysis, only the sitting flexion test obtained a good and statistically significant intraexaminer agreement. Further studies are necessary to evaluate the reliability and validity of these tests.

Complications following equine sacroiliac region analgesia are uncommon: A study in 118 horses.

BACKGROUND: Diagnosis of sacroiliac region pain is supported by a positive response to sacroiliac region analgesia (SIRA). Varying techniques have been described for SIRA; with clinician preference often dictating method. Potential complications following SIRA include ataxia and recumbency. No study has specifically evaluated the prevalence of complications. OBJECTIVES: To describe the complication prevalence following SIRA in a referral clinic. STUDY DESIGN: Retrospective cohort study. METHODS: Review of records from horses presented to two of the authors at Rossdales, Newmarket, between January 2014 and December 2018, that underwent SIRA. Injection was performed using a blind midline approach with 20 mL mepivacaine (Intra-Epicaine 20mg/ml; Dechra) infiltrated through a straight 18 gauge 8.9cm spinal needle subdivided into four sub-locations per block. RESULTS: 118 horses were included, with 167 individual blocks. One horse showed a mild hindlimb gait abnormality following SIRA, which resolved uneventfully over 3 hours; complication rate 1/118 horses (0.85%; 95% CI: 0,2.5%), 1/167 joints (0.60%; 95% CI: 0,1.8%). SIRA subjectively improved lameness/performance in 132/167 (79%) joints. 49/118 (42%) received bilateral SIRA with 53/118 (45%) evaluated ridden following SIRA. MAIN LIMITATIONS: Small population numbers with low complication prevalence rate. CONCLUSIONS: SIRA, using the described technique, has a low (0.85%) prevalence of complications.

Sacroiliac Joint Dysfunction Treated Using Neural Therapy to the Temporomandibular Joint: A Case Report.

Temporomandibular joint disorders (TMJD) include temporomandibular joint dysfunction and bruxism. Sacroiliac joint dysfunction (SJD) is a frequent cause of non-discogenic low back pain. Studies suggest a relationship between TMJD and SJD; however, the link remains unclear. Neural therapy (NT) utilises local anaesthetic injections to treat pain by normalising a dysfunctional autonomic nervous system held responsible for initiating or propagating chronic pain. A 31-year-old female presented with a 1-year history of mechanical left-sided low back pain and sleep bruxism. Examination revealed crepitation of the left TMJ and a trigger point in the masseter muscle. Range of motion of the spine and hip joints were normal, Patrick and Geanslen tests were positive on the left side. Spine and standing flexion tests were also positive. Magnetic resonance imaging of the lumbar spine and sacroiliac joints were normal. A diagnosis of SJD was made, and the patient was treated using NT. Injections of lidocaine 0.5% to the left TMJ, the masseter muscle and intradermal segmental injections at the level of C4 were administered. The patient's back pain and TMJ tenderness reduced and continued so throughout the 3-month follow-up period. SJD may be related to TMJD, and NT may be used in its treatment.

Multidisciplinary management of patients with pubic osteomyelitis, a rare but serious complication after surgery and radiation therapy for advanced gynaecological cancer.

Pubic osteomyelitis is a rare and often late-onset complication of radiation therapy and surgery for vulvar and vaginal carcinoma. It typically presents with vulvar pain, fever, vaginal discharge and/or gait disorders. Pubic osteomyelitis is often accompanied by fistulas or wound dehiscence in the pelvic area. Its accurate diagnosis and treatment are challenging and require a multidisciplinary team effort. In our patients, multiple combined surgical procedures, long-term antibiotic treatment and days to weeks of hospital admission were necessary to treat pubic osteomyelitis. We emphasise the importance of timely and adequate diagnosis and multidisciplinary approach resulting in a course of treatment that is as effective as possible, limiting the impact on quality of life, which is generally high in this group of patients.

Treatment outcomes of peri-articular steroid injection for patients with work-related sacroiliac joint pain and lumbar para-spinal muscle strain.

OBJECTIVES: Evaluating treatment outcomes of local corticosteroid injections for work-related lower back pain (LBP) as the current evidence for the American College of Occupational and Environmental Medicine guidelines is considered insufficient to recommend this practice. MATERIAL AND METHODS: The authors conducted a retrospective study involving the patients who were treated with peri-articular and lower lumbar corticosteroid injections for work-related LBP at their occupational medicine clinic. RESULTS: Sixty-four patients met the inclusion criteria. The average pain level was reduced from M±SD 5.1±2.0 to M±SD 3.1±2.3 after the corticosteroid injection (p < 0.0001). Thirty-five patients (55%) were discharged to regular duty; 23 (36%) were transferred to orthopedics due to persistent pain; and 6 (9%) were lost to follow-up. CONCLUSIONS: Corticosteroid injections for work-related LBP are effective in reducing pain and enhancing discharge to regular duty. Nonetheless, larger prospective trials are needed to validate these findings. Int J Occup Med Environ Health. 2021;34(1):111-20.

Short-Term Effects of Global Pelvic Manipulation on Knee Joint Position Sense in Asymptomatic Participants: A Double-Blind Randomized Controlled Trial.

OBJECTIVE: The purpose of this study was to evaluate short-term effects of the global pelvic manipulation (GPM) on knee joint position sense (JPS). METHODS: This randomized, controlled double-blind trial included 26 asymptomatic participants (X¯± 25.3; standard deviation ± 4.4 years) who were randomly allocated into 2 groups. Sixteen participants were allocated into the experimental group, in which GPM was performed, and the rest of the participants (n = 10) were included in the control group, which received sham ultrasound therapy. Each participant attended 1 session only, and the evaluations were assessed pretreatment and 5 minutes posttreatment through an isokinetic dynamometer (Biodex Medical Systems), in which the data regarding knee JPS ipsilateral to the manipulated sacroiliac joint were collected. Mann-Whitney and Wilcoxon tests were used, with a 95% significance level. RESULTS: There were no statistically significant differences between the groups concerning active and passive JPS at 30° and 60° (P > .05). The results showed a lack of significant differences between the moments in both groups (P > .05). CONCLUSION: This investigation demonstrated that GPM, with high-velocity low-amplitude thrust, has no effect on knee JPS, suggesting that this manipulative technique does not have a relative effect on muscle spindles and Golgi tendon organ activation in asymptomatic participants.

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.

Effectiveness of the Muscle Energy Technique versus Osteopathic Manipulation in the Treatment of Sacroiliac Joint Dysfunction in Athletes.

BACKGROUND: The study of injuries stemming from sacroiliac dysfunction in athletes has been discussed in many papers. However, the treatment of this issue through thrust and muscle-energy techniques has hardly been researched. The objective of our research is to compare the effectiveness of thrust technique to that of energy muscle techniques in the resolution of sacroiliac joint blockage or dysfunction in middle-distance running athletes. METHODS: A quasi-experimental design with three measures in time (pre-intervention, intervention 1, final intervention after one month from the first intervention) was made. The sample consisted of 60 adult athletes from an Athletic club, who were dealing with sacroiliac joint dysfunction. The sample was randomly divided into three groups of 20 participants (43 men and 17 women). One intervention group was treated with the thrust technique, another intervention group was treated with the muscle-energy technique, and the control group received treatment by means of a simulated technique. A prior assessment of the range of motion was performed by means of a seated forward flexion test, a standing forward flexion test, and the Gillet test. After observing the dysfunction, the corresponding technique was performed on each intervention group. The control group underwent a simulated technique. A second intervention took place a month later, in order to ascertain possible increased effectiveness. RESULTS: Statistically significant differences were found between the muscle energy technique (MET) and muscle energy groups compared with the placebo group in both interventions (p = 0.000), with a significant reduction in positive dysfunction (initially 20 in all groups, eight in MET group, and two in thrust group in the final intervention). Comparing the changes in time, only the thrust group obtained statistically significant differences (p = 0.000, with a reduction of positive dysfunction, starting at 20 positives, five positive in the initial intervention and two positive in the final intervention) and when comparing both techniques, it was observed that between the first intervention and the final intervention, the thrust technique was significantly higher than the MET technique (p = 0.032). CONCLUSIONS: The thrust manipulation technique is more effective in the treatment of sacroiliac dysfunction than the energy muscle technique, in both cases obtaining satisfactory results with far middle-distance running athletes. Finally, the thrust technique showed positive results in the first intervention and also in the long term, in contrast to the MET technique that only obtained changes after the first intervention.
