Prevalence of piriformis syndrome in chronic low back pain patients. A clinical diagnosis with modified FAIR test

Kean Chen C, Nizar AJ

Pain Pract, 2013 Apr;13(4):276-81.
PMID: 22863240 DOI: 10.1111/j.1533-2500.2012.00585.x

Piriformis syndrome is a collection of symptoms and signs of pain from piriformis muscle and is characterized by pain in buttock with variable involvement of sciatic nerve. This syndrome is often overlooked in clinical practice because its presentation has similarities with other spine pathologies. A major problem with the clinical diagnosis of piriformis syndrome is the lack of consistent objective findings and an absence of single test that is specific for piriformis syndrome. Therefore, a precise and reliable clinical method of diagnosing piriformis syndrome should be developed by clinicians.

BACKGROUND: Malaysian office workers often experience Musculoskeletal Discomfort (MSD) which is typically related to the low back, shoulders, and neck.
OBJECTIVES: The objective of this study was to examine the occurrence of lower back, shoulder, and neck pain among Malaysian office workers.
METHODS: 752 subjects (478 women and 274 men) were randomly selected from the Malaysian office workers population of 10,000 individuals. The participants were aged between 20-50 years and had at least one year of work experience. All participants completed the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). Instructions to complete the questinnaire were given to the participants under the researchers supervision in the morning before they started a day of work. The participants were then classified into four categories based on body mas index (BMI) (BMI:≤18.4, 18.5-24.99, 25-29.99, ≥30) and age (Age: 20-29, 30-39, 40-49, ≥50).
RESULTS: There was a significant association between pain severity in gender and right (p = 0.046) and left (p = 0.041) sides of the shoulders. There was also a significant association between BMI and severity of pain in the lower back area (p = 0.047). It was revealed that total pain score in the shoulders was significantly associated with age (p = 0.041).
CONCLUSIONS: The results of this study demonstrated that a significant correlation existed between pain servity for gender in both right and left shoulder. These findings require further scientific investigation as do the identification of effective preventative stratgies.

Incidence of urolithiasis is on the rise due to climatic changes especially global warming.The pain due to presence of ureteric stone is a well known identity but many times it may be asymptomatic or even masked by concurrent presence of backache. In the present article, we describe the case of a 43-year-old male who came to the clinic for treatment of backache persisting for more than two years. The patient complained of backache two years back for which he was treated with analgesics and physiotherapy which relieved his pain. No X-ray was taken earlier because the attending clinician thought the backache to be musculo-skeletal in origin. Recently, one day a sudden episode of backache in the midst of night compelled him to seek medical treatment. However, this time a X-ray was performed and it showed the presence of calculi in the right upper pelvis of ureter which measured 1.9 cm vertically. An ultrasound confirmed the diagnosis. The patient was treated with two episodes of shock wave therapy which failed to crush the stone. A Double-J stent was inserted under general anaesthesia. The stone was crushed using a ureteroscope guided laser. The present case report describes how backache in professionals cannot be lightly attended. Even the characteristic groin to loin pain may be absent. All cases of backache should be properly investigated with an X-ray to rule out renal or ureteric calculi.
