“…This study found a high proportion of patients (278 of 828, 33.6%) with paraspinal pain in the past month. However, in a clinical setting patients frequently present with gluteal pain[63, 64]. Thus, the small proportions with point or 1-month period prevalence of gluteal pain were unexpected.…”

BackgroundLow Back Pain (LBP) is a common and costly problem, with variation in prevalence. Epidemiological reports of rating of pain intensity and location within the low back area are rare. The objective is to describe LBP in a large, multi-center, occupational cohort detailing both point and 1-month period prevalence of LBP by location and intensity measures at baseline.MethodsIn this cross-sectional report from a prospective cohort study, 828 participants were workers enrolled from 30 facilities performing a variety of manual material handling tasks. All participants underwent a structured interview detailing pain rating and location. Symptoms in the lower extremities, demographic and other data were collected. Body mass indices were measured. Outcomes are pain rating (0–10) in five defined lumbar back areas (i) LBP in the past month and (ii) LBP on the day of enrollment. Pain ratings were reported on a 0–10 scale and subsequently collapsed with ratings of 1–3, 4–6 and 7–10 classified as low, medium and high respectively.Results172 (20.8%) and 364 (44.0%) of the 828 participants reported pain on the day of enrollment or within the past month, respectively. The most common area of LBP was in the immediate paraspinal area with 130 (75.6%) participants with point prevalence LBP and 278 (77.4%) with 1-month period prevalence reported having LBP in the immediate paraspinal area. Among those 364 reporting 1-month period prevalence pain, ratings varied widely with 116 (31.9%) reporting ratings classified as low, 170 (46.7%) medium and 78 (21.4%) providing high pain ratings in any location. Among the 278 reporting 1-month period prevalence pain in the immediate paraspinal area, 89 (32.0%) reported ratings classified as low, 129 (46.4%), medium and 60 (21.6%) high pain ratings.ConclusionsPain ratings varied widely, however less variability was seen in pain location, with immediate paraspinal region being the most common. Variations may suggest different etiological factors related to LBP. Aggregation of different locations of pain or different intensities of pain into one binary classification of LBP may result in loss of information which may potentially be useful in prevention or treatment of LBP.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2474-15-283) contains supplementary material, which is available to authorized users.

“…3,5 Previous studies have shown that female suffer more from piriformis syndrome than male, although with varying proportions, Danilo et al found a ratio of female compared to male 6: 1, Chen et al reported a ratio of 3:2. 3,6 Predisposing female in piriformis syndrome may be caused by anatomical angle of the quadriceps femoris muscle in the women pelvis is wider than men. 7 Other studies reported that hormonal changes in women especially during pregnancy can also affect the occurrence of piriformis syndrome.…”

“…6 Park et al examined the relationship between BMI and piriformis muscular abnormalities in inactive populations through Computed Tomography (CT) imaging and concluded that an increase in BMI resulted increase in the distance between the piriformis muscle and the surrounding subcutaneous tissue. 6,9 These abnormalities might trigger the occurrence of piriformis syndrome. However, the correlation between the incidence of piriformis syndrome and the increase in BMI still requires further study.…”

Background: Piriformis syndrome is a neuromuscular condition characterized by hip and gluteal pain caused by abnormality of piriformis muscle. In clinical practice, this syndrome is usually misdiagnosed with other spinal disorders. There is no specific test in diagnosing piriformis syndrome, therefore by understanding the characteristics and predisposing factors, clinicians may be more aware in diagnosing this syndrome. Objective: To investigate the characteristics and predisposing factors of piriformis syndrome. Methods: A descriptive study was conducted on patients with gluteal pain in a referral hospital. Diagnosis was established by block injection on piriformis muscle and showed clinical improvement afterwards. Demographic characteristics, predisposing factors, and physical examination were analyzed. The data is collected and processed by SPSS 20.0. Results: The total of 65 patients were evaluated, with a male to female ratio 1:3. As much as 47.7% of patients were > 60 years old. Average weight was 60 kg and BMI (Body Mass Index) was within normal range (58.9%). Most subjects were housewives (55.4%) and the majority of subjects had history of microtrauma such as sitting on rigid surfaces (36.9%), walking or running long distances (18.5%), and cross-legged sitting (10.8%). Average sitting per day was approximately 5 hours. In 56.9% of subjects, exercises were conducted. There was no history of back pain in 81.5% of subjects. Conclusion: Our study showed age and housewives characteristics differ with other studies. The most predisposing factors were history of microtrauma, female, age, and normal BMI.

“…FBSS is characterized by recurrent or residual back pain after spinal surgery, and it has a reported incidence of 20-40% [56], which increases the likelihood of the patient suffering from PMS as part of the constellation of the painful symptoms. PMS is prevalent in 13.7% of the general population, in 17% of low LBP patients [57], and reaching 40.4% of chronic LBP post discectomy patients [13].…”

Piriformis Muscle Syndrome, Post Discectomy: a Comprehensive Review of its Diagnostic Process and Management, Illustrated with the Aid of a Case Report

This review, with the help of a case study, provides a detailed account of the possible biopsychosocial risk factors underlying piriformis muscle syndrome, post discectomy. The diagnostic process including imaging, nerve conduction studies, musculoskeletal examination coupled with provocation maneuvers, palpation, and the musculoskeletal differential diagnosis of buttock pain is illustrated. Reference is made to the aberrant sciatic nerve anatomy and to the myofascial component which is frequently reported to underlie piriformis muscle syndrome. Additionally, the use of validated neuropathic pain assessment tools in grading the possibility of neuropathic pain due to piriformis muscle syndrome is discussed. The prevalence and mechanisms of piriformis muscle syndrome, especially post sipnal surgery, are reviewed. Evidence-based multidisciplinary management underlying this condition is discussed. In refractory cases, treatment escalation, using intramuscular botulinum neurotoxin injection, usually yields very positive results and long-term pain resolution, as evidenced by the case study.

Prevalence of Piriformis Syndrome in Chronic Low Back Pain Patients. A Clinical Diagnosis with Modified FAIR Test

Abstract: Piriformis syndrome is a painful condition that is often overlooked in the differential diagnosis of chronic buttock or low back pain. The modified FAIR test together with piriformis muscle injection is potentially a reliable method for the clinical diagnosis of piriformis syndrome.
