Physical Activity, Disability and Quality of Life Before and After Lumbar Spine Surgery (PA-LSS)

September 17, 2019 updated by: University Hospital, Basel, Switzerland

Accelerometry-based Physical Activity, Disability and Quality of Life Before and After Lumbar Spine Surgery: a Prospective Study

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Physical activity
Time Frame: up to 12 weeks
measured using ActiGraph (accelerometer based activity monitor) as step counts, physical activity intensity during 7-day data capture period
up to 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disability
Time Frame: up to 12 weeks
measured using Oswestry Disability Index (questionnaire) (best score: 0 - no disability, worst score: 100)
up to 12 weeks
Quality of life assessed by questionnaire
Time Frame: up to 12 weeks
measured using Short Form (SF)-36 (questionnaire) (worst score: 0; best score: 100 - highest quality of life)
up to 12 weeks
Pain assessed by questionnaire
Time Frame: up to 12 weeks
measured using 10 cm visual analogue scale (VAS) lower back, legs (best score: 0 - no pain; worst score: 100)
up to 12 weeks

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
