Muscle Strength Evaluations in Ankylosing Spondylitis

Summary

This study evaluates how the trunk and proximal girdle muscles are affected in male patients with ankylosing spondylitis, compared to healthy controls.

Conditions

• Ankylosing Spondylitis

Interventions

OTHER

Truncal flexion-extension muscle power

Patient performs a maximum truncal flexion laying supine on the bed with cap of muscle tester placed on sternum,

OTHER

Truncal extension muscle power

Patient performs a maximum truncal extension laying prone on the bed while the cap of manual muscle tester placed on vertebrae at the level of midline between superior angles of scapulae.

OTHER

Cervical flexion muscle power

Patient performs a maximum cervical flexion sitting while the cap of manual muscle tester placed on the middle of the forehead.

OTHER

Cervical extension muscle power

Patient performs a maximum cervical extension sitting while the cap of manual muscle tester placed on protuberantia occipitalis.

OTHER

Cervical lateral flexion muscle powers

Patient performs a maximum cervical lateral flexions on right and left sitting while the cap of manual muscle tester placed on relevant pterion.

OTHER

Shoulder flexion muscle power

Patient performs a maximum shoulder flexion of the dominant side on upright while the cap of manual muscle tester placed on midpoint of the line between anterior aspect of acromion and anterior elbow.

OTHER

Shoulder extension muscle power

Patient performs a maximum shoulder flexion of the dominant side on upright while the cap of manual muscle tester placed on midpoint of the line between posterior aspect of acromion and posterior elbow.

OTHER

Shoulder internal rotation muscle power

Patient performs a maximum shoulder internal rotation of the dominant side on upright while the cap of manual muscle tester placed on midpoint of the line between anterior elbow and wrist.

OTHER

Shoulder external rotation muscle power

Patient performs a maximum shoulder external rotation of the dominant side on upright while the cap of manual muscle tester placed on midpoint of the line between posterior elbow and wrist.

OTHER

Shoulder abduction muscle power

Patient performs a maximum shoulder abduction of the dominant side on upright while the cap of manual muscle tester placed on midpoint of the line lateral aspect of acromion and lateral epicondyle.

OTHER

Hip flexion muscle power

Patient performs a maximum hip flexion laying supine on the bed while the cap of manual muscle tester placed on middle of the anterior thigh.

OTHER

Hip extension muscle power

Patient performs a maximum hip extension laying prone on the bed while the cap of manual muscle tester placed on middle of the posterior thigh.

OTHER

Hip abduction muscle power

Patient performs a maximum hip abduction laying supine on the bed while the cap of manual muscle tester placed on middle of the lateral thigh.

OTHER

Hip internal rotation muscle power

Patient performs a maximum hip internal rotation laying supine on the bed while the cap of manual muscle tester placed on the midline between lateral condyle of femur and lateral malleolus.

OTHER

Hip external rotation muscle power

Patient performs a maximum hip external rotation laying supine on the bed while the cap of manual muscle tester placed on the midline between medial condyle of femur and medial malleolus.

OTHER

Bath Ankylosing Spondylitis Functional Index (BASFI)

This questionnaire evaluates the functionality in patients with AS. The ten questions that comprise the BASFI were chosen with input from patients with AS. The first 8 questions evaluate activities related to functional anatomical limitations due to the course of this inflammatory disease. The final 2 questions evaluate the patients' ability to cope with everyday life. A visual analogue scale (with 0 being "easy" and 10 "impossible) is used to answer the questions on the test. The final score varies between 0 and 10.

OTHER

Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

This questionnaire evaluates the disease activity level in patients with AS. The BASDAI consists of a 0 - 10 scale measuring discomfort, pain, and fatigue (0 being no problem and 10 being the worst problem) in response to six questions asked of the patient pertaining to the five major symptoms of AS. The final score varies between 0 and 10.

OTHER

The Health assessment questionnaire (HAQ)

The Health assessment questionnaire (HAQ) is a questionnaire for the assessment of disability in an individual. The patients report the amount of difficulty they have in performing eight daily living activities. Each question asks on a scale ranging from 0 to 3 if the categories can be performed without any difficulty (scale 0) up to cannot be done at all (scale 3). The final score varies between 0 and 3.

OTHER

Bath Ankylosing Spondylitis Metrology Index (BASMI)

Bath Ankylosing Spondylitis Metrology Index, a combined index to assess the spinal mobility. It evaluates the patients regarding cervical rotation, tragus-to-wall distance, lumbar flexion, lumbar lateral flexion and intermalleolar distance. The total score varies between 5 to 15 in patients with ankylosing spondylitis
