Lumbar Proprioception in Patients With Lumbar Spinal Stenosis
Condition: Spinal Stenosis Lumbar
MeSH terms: Spinal Stenosis; Constriction, Pathologic
Study type: Observational [Patient Registry]

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.
    

Intervention name(s): 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.
Intervention type(s): Other
Intervention description(s): Target positions of reposition error were: 30º forward bending and 15º backward bending in sitting and standing.
Observational model: Case-Control
Time perspective: Cross-Sectional

Study population: 
        Group I consists of patient relatives and patients who applied to the outpatient clinic for
        another ailment.

        Group II consisted of patients diagnosed with LSS and confirmed by MRI findings.

        Participants who have undergone surgery due to LSS were included in Group III.
