Ultrasonographic Measurements of the Achilles Tendon and Talar Condylar Cartilage Thickness in Paraplegia Patients.

Investigators aim to measure the ankle talar cartilage and achilles tendon thicknesses ultrasonographically in paraplegic patients and compare them with the normal population.

Study Overview

• Status: Active, not recruiting
• Conditions: Paraplegia
• Intervention / Treatment: Device: Ultrasonographic evaluations

Detailed Description

Paraplegia is a clinical condition that expresses the loss of motor and sensory function in the lower extremities after spinal cord injury. A specialized and intensive rehabilitation program is needed in these patient groups who develop immobilization. In healthy individuals, there is a certain biomechanics of the lower extremity. In paraplegic patients, this biomechanics changes due to weakness in the lower extremities. These biomechanical changes can cause different loads and effects on the lower extremity joints, muscles, tendons, and articular cartilages of paraplegic patients. Among the rehabilitation goals of paraplegic patients, it is to stand up and walk the patient with or without support, with or without a device. During this rehabilitation, the position and function of the ankle is important. In this process, the talar condylar cartilage and achilles tendon forming the ankle joint can be exposed to different loads.

Ultrasonography is frequently used in physical therapy practice because it does not contain any radiation, has no side effects to the patient, facilitates dynamic and real-time evaluation of joint and muscle conditions and functions, and provides guidance during interventional procedure planning. In this study, investigators aim to ultrasonographically measure ankle talar cartilage and Achilles tendon thicknesses in paraplegic patients with long-term immobilization and compare them with the normal population.

Our study will be organized as a observational study. It is planned to include 20 paraplegia patients and 20 healthy volunteers in the study.

Demographic data of the patients and healthy volunteers will be recorded. Paraplegia patients will be evaluated in terms of Barthel Index, Modified Ashworth Scale, American Spinal Injury Association (ASIA) scale, Walking Index for Spinal Cord Injury Scale (WISCII-2).

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Control	Device: Ultrasonographic evaluations; Ultrasonographic evaluations of the talar cartilage will be performed with an 8 MHz linear probe (B-K Medical Ultrasound Scanner Class I Type B) by the same physiatrist according to the European Musculoskeletal Ultrasound Study Group (EURO-MUSCULUS). Ultrasonographic evaluations of the Achilles tendon will be performed by the same physiatrist with an 8 MHz linear probe (B-K Medical Ultrasound Scanner Class I Type B) according to the European Musculoskeletal Ultrasound Study Group (EURO-MUSCULUS).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ankle talar cartilage thicknesses	Patients will lie on the examination table supine with their knees flexed to 90 degrees and ankles in a flat-footed position. The probe was placed mid-longitudinally over the ankle joint to assess the cartilage of the talar dome. The articular cartilage will be displayed as an anechoic line between bony cortex and adipose tissue. Cartilage thickness will be measured by drawing a straight line from the bone-cartilage interface to the cartilage-fatty tissue interface at the midpoint of the talar dome. The thickness of the hyaline cartilage will be measured in centimeters (cm).	1 day
Achilles tendon thicknesses	Ultrasound (US) evaluation will be performed with patients in the prone position on examination table with their feet in 90 degrees of flexion. Achilles tendon of the each patient and healthy volunteer will be scanned. Antero-posterior achilles thickness will be measured on the same mid-longitudinally scan at two different levels: at the insertion of the achilles tendon deeper edge into the calcaneal bone and 3 cm more proximal. The thickness of the achilles tendon will be measured in centimeters (cm).	1 day
