Quality of Life, Psychosocial Burden, and Structural-functional Status in Adults With Spinal Deformity. (ASD-QoL)

4 augustus 2026 bijgewerkt door: Universitaire Ziekenhuizen KU Leuven

This study examines which factors influence quality of life in adults with a spinal deformity. It looks at imaging findings together with pain, daily functioning, psychosocial factors, and frailty to support more person-centred care.

A total of 320 adults will participate in three groups: conservative treatment, first corrective surgery, or reoperation. All care follows standard practice; no experimental treatments are added. Participants complete questionnaires, and routine FASD tests and existing EOS/X-ray images may be used.

Follow-up lasts up to 2 years, with scheduled assessments depending on whether treatment is surgical or conservative.

Gedetailleerde beschrijving

This study investigates which factors are associated with quality of life in adults with a spinal deformity. Among patients with a comparable spinal alignment, pain, daily functioning, and quality of life can vary greatly. Therefore, the study examines not only the structural abnormality on medical imaging, but also pain, limitations in daily functioning, anxiety and low mood, fear of movement, concern about falling, participation in daily life, and overall frailty. The results may contribute to a more person-centred assessment and treatment of adults with a spinal deformity.

A total of 320 adults with a spinal deformity will be included. The study compares three groups: patients treated conservatively, patients undergoing a first corrective surgery, and patients undergoing a reoperation. Treatment is entirely determined by the regular care team; the study does not add any experimental intervention. Participants complete questionnaires on quality of life, back symptoms, functioning, and psychosocial well-being. Where applicable, the Function Assessment Scale for Spinal Deformity (FASD) is administered, a functional movement test that is part of standard care. Available EOS or X-ray images from routine care are used; no additional images are taken solely for the study.

Follow-up lasts up to 2 years. For surgically treated participants, assessments may take place at surgery and around 6 weeks, 4 months, 1 year, and 2 years post-operatively. Conservatively treated participants are assessed at baseline and, where appropriate within routine care, around 1 and 2 years.

Beschrijving

Inclusion Criteria:

  1. Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures
  2. Age at inclusion 18 years or older.
  3. Diagnosed with Adult spinal deformity

  4. Planned routine management through one of the following pathways:

    1. Conservative/non-operative management;
    2. Primary ASD surgery;
    3. Revision ASD surgery.
  5. Ability to complete the Dutch-language questionnaire package.

Exclusion Criteria:

  1. No valid informed consent.
  2. Missing baseline structural imaging required for endpoint determination. We allow images to be older than 2 years if no new radiographs are obtained, in accordance with the ALARA principle.
  3. Inability to complete the Dutch-language questionnaire package.
  4. Known cognitive impairment, severe psychiatric condition, or other condition that, in the Investigator's judgement, precludes valid informed consent or reliable completion of study assessments.
  5. Primary spinal condition other than adult spinal deformity that is expected to invalidate endpoint assessment, including acute traumatic, infectious, tumour-related, or inflammatory spinal pathology as the main reason for presentation.

Tijdsspanne
Cross-sectional associations in QoL between conservative, primary surgery, and revision surgery study groups.
Tijdsspanne: within a period of 2 year
QoL is measured using the SRS-22r questionnaire during screening visit, at 6-weeks, 4 months, 1 year and 2 year.For Scoliosis Research Society 22 Revised (SRS-22r) questionaire a patient reported measure of health related quality of life in individuals with scoliosis. PROM assessing five domains: Function/Activity, Pain, Self image/Appearance, Mental Health, Satisfaction with Management. The mean score is located between 5 (Best) and 1 (Worst).

Cross sectional associations in QoL between conservative, primary surgery, and revision surgery study groups.

QoL is measured using EQ-5D-5L questionnaire questionnaire during screening visit, at 6-weeks, 4 months, 1 year and 2 year The EuroQol 5 Dimension 5 Level(EQ-5D-5L) include 5-digit health profile: Mobility, Self Care, Usual Activities, Pain/Discomfort, Anxiety/Depression converting it to an index value using the country-specific value set (range -0.59 to 1.0). EQ-5D-5L score expresses health status as a utility value ranging from <0 (worse than death) to 1 (full health). Higher values indicate better overall health.

QoL is measured using VAS questionnaire during screening visit, at 6-weeks, 4 months, 1 year and 2 year The Visual Anlog Score (VAS) - ranges from 0 to 100, where 0 means "worst imaginable health" and 100 means "best imaginable health." A higher VAS score reflects better self perceived health.

Cross sectional associations in QoL between conservative, primary surgery, and revision surgery study groups.
Tijdsspanne: Withing 2 years
QoL in non-revision ASD patients, adjusted for structural deformity severity, demographic characteristics, treatment pathway, and frailty-related health status. Structural covariates include Sagittal Vertical Axis(SVA), Pelvic tilt(PT), Pelvic incidence-lumbar lordosis mismatch (PI-LL) mismatch, and coronal Cobb angle. Frailty-related health status will be measured using the mFI-5. The modified 5-item frailty index (mFI-5) which assesses five clinical deficits: diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functional dependence. Each deficit is scored as 0 (absent) or 1 (present). The unit of measure is the total frailty score ranging from 0 to 5, where higher scores indicate greater frailty.

Measures include HADS during screening visit, at 6-weeks, 4 months, 1 year and 2 year. Hospital Anxiety and Depression Scale (HADS) a validated 14 item self report questionnaire assessing symptoms of anxiety and depression. Each item is scored on a 0-3 Likert scale, and the unit of measure is the subscale total score for Anxiety (HADS A, range 0-21) and Depression (HADS D, range 0-21). Higher scores indicate more severe symptoms.
