The Relationship Between Ambulation Capacity and Piriformis Muscle in Patients With Chronic Spinal Cord Injury
Study Details
Study Description
Brief Summary
Spinal cord injury (SCI) is a neurological condition causing paralysis, sensory abolishmentS and deficits including circulatory, respiratory, otonomic nervous systems, bowel and bladder functions. For patients with SCI, reducing disability, limitations of the impairment and regaining the walking ability are the main rehabilitation goals. There many prognostic factors effecting the recovery and ambulation capacity of patients.
The piriformis muscle (PM) is placed posterior to the hip joint, originates on the anterior surface of the sacrum and the sacrotuberous ligament and passes out of the pelvis through the greater sciatic foramen and separates the foramen into two spaces. The PM is the solely muscle coursing transversely throughout the greater sciatic notch, and it is the main landmark to all the important neurovasculer structures that pass from the pelvis to the gluteal region. PM serves as a hip abductor when the hip is flexed and as a hip external rotator when the hip is extended. It is innervated by branches of the posterior division of the ventral rami of S1, S2 and is the largest muscle among the deep, short external rotators of the hip and provides postural stability while standing and walking. PM has also a functional importance as it connects the sacroiliac joint and hip joint. For these reasons morphology of PM may have a clinical importance for SCI patients whom can walk.
Ultrasonography is radiation-free, noninvasive, available technique that can be used to measure muscle thickness in the monitoring and management of muscle changes during rehabilitation.
The aim of our study is to evaluate the relationship between the PM and the ambulation pattern of motor incomplete patients with chronic SCI. To the best of our knowledge, this is the first study evaluating PM in patients with SCI.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Motor incomplete paraplegia patients Participants with the age of 18 - 65, were selected for the study based on the following inclusion criteria: diagnosis of motor incomplete paraplegia at C or D level according to the spinal cord injury classification of the American Spinal Injury Association (ASIA) Impairment Scale with a neurological injury level between T2-S1. |
Other: Ultrasonographic evaluation
Ultrasonographic evaluation for the thickness of piriformis muscle

| Non-ambulatory patients with complete spinal cord injury Participants with the age of 18 - 65, were selected for the study based on the following inclusion criteria: non-ambulatory patients with diagnosis of motor complete paraplegia at A level according to the spinal cord injury classification of the American Spinal Injury Association (ASIA) Impairment Scale with a neurological injury level between T2-S1. |
Other: Ultrasonographic evaluation
Ultrasonographic evaluation for the thickness of piriformis muscle

Outcome Measures
Primary Outcome Measures
- piriformis muscle thickness with ultrasonographic evaluation [Through study completion, an average of one and a half months]
The thickness of piriformis muscle was measured by using a curvilinear transducer first placing in the lateral margin of the sacrum. The transducer was moved inferolaterally toward the greater trochanter until the medial end of the transducer remained at the lateral end of the sacrum. Piriformis muscle thickness was measured in the medial part of the tip of the ischium, that was parallel to the longitudinal plane at the sciatic notch with the patient's leg was abducted 45 degrees when the piriformis muscle was seen as a deep hypoechoic appearance beneath the gluteus maximus muscle.
