The Spinal Stenosis Pedometer and Nutrition e-Health Lifestyle Intervention (SSPANLI) Trial
Study Details
Study Description
Brief Summary
Obesity is one of the most important determinants of quality of life and function. People with lumbar spinal stenosis may be at increased risk of obesity given walking limitations. Spinal stenosis is a very common degenerative condition in people over 45. People with this condition have pain and numbness in the legs during walking, and therefore avoid physical activity. Lack of physical activity is related to weight gain and increased risk of chronic disease. Objective: The objective of this project is test a new e-health (online) pedometer and nutrition intervention aimed at promoting weight loss and increasing physical activity in overweight and obese individuals with spinal stenosis. Methods: The investigators will recruit 88 people with lumbar spinal stenosis who are overweight or obese. Half of these people will receive the 12-week intervention, and the other half will receive usual care (no intervention). In Weeks 1 and 6, people in the intervention group will meet with a Registered Dietitian and an Exercise Physiologist for personalized sessions. They will receive a pedometer and instructions on how to log in to the e-health site (https://sspanli.mtroyal.ca). They will wear the pedometer daily and log in to the website each week for a nutrition education session, a weekly step goal, and tips. The investigators will look to see whether people in the intervention group show greater change in physical activity, body composition and quality of life compared to the individuals who received usual care. Relevance: The increasing number of people with spinal stenosis represents a huge health care burden in Canada. This intervention could provide a new treatment option that would increase mobility, quality of life, and potentially alleviate the need for expensive treatments like surgery. E-health interventions provide an opportunity for patients to take an active role in their own health, and promote behaviour changes that will result in healthier Canadians less likely to access care in the future.

Outcome Measures
Primary Outcome Measures
- Change from Baseline in Percent Fat Mass at 6 months [6 months]
Fat mass will be assessed at both Baseline and 6 month follow-up using dual energy x-ray absorptiometry and presented as a percentage of total body mass.
- Change from Baseline in Mean Number of Steps Per Day at 6 months [6 months]
Steps per day will be assessed at both Baseline and 6-month follow-up using a pedometer worn for 7 consecutive days
- Change from Baseline in Waist Circumference (Centimeters) at 6 months [6 months]
Waist circumference will be assessed at both Baseline and 6-month follow-up using a tape measure and recorded in centimetres
Eligibility Criteria
Criteria
Inclusion Criteria:
- All subjects will be at least 45 years of age and will have received a diagnosis of lumbar spinal stenosis (LSS) by a spine surgeon who has both examined the patient and reviewed imaging results (MRI or CT). All subjects will be required to have a BMI of 25 kg/m2 or greater (overweight) and to have maintained a stable body weight for the previous 3 months.
Exclusion Criteria:
-
any co-morbid conditions that would make participation in a walking program medically inadvisable.
-
subjects currently participating in a diet or lifestyle intervention for weight loss or who are on medications known to influence bodyweight or glucoregulation (including antidepressants, sibutramine orlistate, insulin and metformin), will be excluded.
If participants are scheduled for any type of surgery that could impact mobility during the intervention period, they will be removed from the study.
