About this trial

Lumbar spinal stenosis (LSS) is one of the most common degenerative diseases of the spinal column, with symptoms including low back pain which worsens with ambulation, poor balance, decreased activity due to pain, and a marked decrease in quality of life (QoL). Prevalence rises with age, and current treatment options range from varied conservative management strategies, to surgical intervention with decompression of neural structures.

While the effects of surgical decompression on back pain and QoL has been widely researched, the effects of surgery on activity levels is less well understood. Though patients generally have subjective improvements in this parameter after surgery, objective measurements in this patient group have been lacking.

This study aims to investigate the effects of decompressive surgery on activity levels in elderly patients with LSS. Measurements of activity will be taken before and after decompressive surgery, as well as with regular intervals during a two-year follow-up period.

A better understanding of the effect that LSS has on activity may lead to more patients being able to receive surgical treatment, which is hypothesized to lead to an increase in QoL and less perceived disability amongst this patient group.

Trial outcomes

Primary outcomes

1

Activity level

Activity level, measured by total activity counts per day (TAC/d)

Time frame
Before surgery and 3, 6, 12 and 24 months after surgery

Secondary outcomes

1

Physical activity

Physical activity, measured by time spent in MVPA (minutes/day)

Time frame
Before surgery and 3, 6, 12 and 24 months after surgery
2

Physical activity

Physical activity, measured by physical activity energy expenditure (PAEE) (Kilojoules/d)

Time frame
Before surgery and 3, 6, 12 and 24 months after surgery
3

Physical inactivity

Physical inactivity, measured by sedentary time (hours/d)

Time frame
Before surgery and 3, 6, 12 and 24 months after surgery
4

Quality of life

Subjective QoL, measured by European Quality of Life - 5 Dimensions score (EQ-5D) The EQ-5D consists of six questions regarding current perceived health status and quality of life. Questions 1 - 5 have a range of 1 to 3, lower is better. The answer to questions 6 is given on a scale of 0 to 100, where lower is better.

Time frame
Before surgery and 3, 6, 12 and 24 months after surgery
