Physical Activity, Disability and Quality of Life Before and After Lumbar Spine Surgery

An observational study in Lumbar Spine Degeneration, Physical Activity and Quality of Life, sponsored by University Hospital, Basel, Switzerland. Completed at 2 sites in Switzerland. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2019-09-18.

Why
  1. Motor Activity is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Pain.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

To date it is unknown how physical activity levels in adults is limited before and after lumbar spine surgery and if physical activity level is associated with disability and limitations of quality of life. The main objective is to compare physical activity preoperatively and 6 and 12 weeks postoperatively in patients undergoing lumbar spine surgery with norm data. In addition, the investigators will study the association of changes in physical activity, disability and quality of live.

Read the detailed description

Patients scheduled for planned lumbar spine surgery will be contacted to participate in this study. All outcomes will be assessed within 1 week preoperatively and at 6 and 12 weeks postoperatively. Changes in outcome scores will be detected using analysis of variance. Association of changes in physical activity and changes in secondary outcomes will be detected using stepwise linear regression models.

What researchers measure

Primary outcomes

  1. Physical activity

    measured using ActiGraph (accelerometer based activity monitor) as step counts, physical activity intensity during 7-day data capture period

    Time frame: up to 12 weeks

Secondary outcomes

  1. Disability

    measured using Oswestry Disability Index (questionnaire) (best score: 0 - no disability, worst score: 100)

    Time frame: up to 12 weeks

  2. Quality of life assessed by questionnaire

    measured using Short Form (SF)-36 (questionnaire) (worst score: 0; best score: 100 - highest quality of life)

    Time frame: up to 12 weeks

  3. Pain assessed by questionnaire

    measured using 10 cm visual analogue scale (VAS) lower back, legs (best score: 0 - no pain; worst score: 100)

    Time frame: up to 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2017 to primary completion in May 2018, 11 months.

Of 504 non-industry observational studies under Pain, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 42. This study's 11 months is below that.

Counting every sponsor, half of 519 studies reached it within 18 months; a quarter within 8 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 18, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
