Lumbar Proprioception in Patients With Lumbar Spinal Stenosis

Completed

• Conditions: Spinal Stenosis Lumbar
• Interventions: Other: Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively.

• Registration Number: NCT05548608
• Lead Sponsor: Pamukkale University

Brief Summary

The primary aim of this study was to compare spinal proprioception in patients with Lumbal Spinal Stenosis (LSS) (with or without surgery) and healthy controls. A secondary aim was to investigate the effect of pain at target positions where repositioning error (RE) was assessed and TLF flexibility on spinal proprioception deficiency.This cross-sectional and healthy controlled study was conducted in patients with LSS. Participants will be grouped as: Healthy control (Group I), chronic low back pain due to LSS (Group II) and undergoing surgery due to LSS (Group III). Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively. Target positions of reposition error were: 30º forward bending and 15º backward bending in sitting and standing.

Detailed Description

This cross-sectional and healthy controlled study was conducted in patients with LSS. Participants will be grouped as: Healthy control (Group I), chronic low back pain due to LSS (Group II) and undergoing surgery due to LSS (Group III). Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively. Target positions of reposition error were: 30º forward bending and 15º backward bending in sitting and standing.

The general study inclusion criteria were as follows: age between 20 and 50 years and not having had lower extremity surgery.

In addition to the general inclusion criteria, the inclusion criteria for the control group were as follows: not having a chronic spinal disorders and not having low back pain in the last week. Group II consisted of patients diagnosed with LSS and confirmed by MRI findings.

In addition to the general inclusion criteria, the inclusion criteria for the LSS group were as follows: having low back pain for more than 3 months and having low back pain intensity of 4 or more assessed with VAS.

There was not any additional inclussion criteria for Group III. The exclusion criteria of current study are; having any previous inner ear inflammation or vestibular disorders, having diabetes and being pregnant.

Arm && Interventions

Group	Intervention	Description
Group II (chronic low back pain due to LSS )	Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively.	Group II consisted of patients diagnosed with LSS and confirmed by MRI findings.
Group III (undergoing surgery due to LSS )	Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively.	Participants who had surgery for LSS at least 3 months ago were included in Group III.
Group I (Healthy control)	Reposition error (RE), pain at target positions of RE and flexibility of the TLF were assesed with iphone tiltmeter app, VAS and goniometric platform, respectively.	Group I consists of patient relatives and patients who applied to the outpatient clinic for another ailment.

Primary Outcome Measures

Name	Time	Method
pain intensity	september 2020-february 2021	. Pain intensity was assessed with the 10 cm horizontal Visual Analogue Scale (VAS) at target positions (during sitting and standing in combination with forward and backward bending)
flexibility of the TLF	september 2020-february 2021	Flexibility of the TLF was evaluated with goniometric platform. The participant was asked to sit on a height-adjustable chair with the hip and knee flexed at 90º and the lumbar region in a neutral position. The goniometric platform was placed on the table in front of the participant. The therapist fixed the posterior superior iliac spines of the participant. And then participants were asked to hold the hands in front of the body (90° shoulder flexion) with a pen clamped between the hands. Participants were warned that the arms should follow the trunk rotation. Participants performed trunk rotation 3 times in the same direction and marked the point on the goniometric platform. The mean of the 3 measurements was calculated. The same protocol was repeated in the opposite direction.
reposition error	september 2020-february 2021	Reposition error was asessed by measuring the difference in angles between the target position and the re-produced position. Target positions were 30º forward bending and 15º backward bending in sitting and standing positions. The target and the reproduced angles were measured with the iPhone tilt-meter application.
