The spinal stenosis pedometer and nutrition lifestyle intervention (SSPANLI): development and pilot.

BACKGROUND CONTEXT

Owing to mobility limitations, people with lumbar spinal stenosis (LSS) are at risk for diseases of inactivity, including obesity. Therefore, weight management in LSS is critical. Body mass index is the strongest predictor of function in LSS, suggesting that weight loss may promote physical activity and provide a unique treatment option. We propose a lifestyle modification approach of physical activity and nutrition education, delivered through an e-health platform.

PURPOSE

The purpose of this study was to develop and pilot an e-health intervention aimed at increasing physical activity and decreasing fat mass in people with LSS.

STUDY DESIGN

The study design was based on intervention development and pilot.

PATIENT SAMPLE

Ten overweight or obese individuals with LSS were confirmed clinically and on imaging.

OUTCOME MEASURES

Self-reported measures were food record, Short-Form 36 (SF-36), pain scales, Swiss Spinal Stenosis Symptom and Physical Function Scales, Oswestry Disability Index (ODI), Pain Catastrophizing Questionnaire, Tampa Scale for Kinesiophobia, Center for Epidemiologic Studies(Depression) Scale, Behavioral Regular in Exercise Questionnaire, and Regulation for Eating Behavior Scale and physiologic measures were dual-energy X-ray absorptiometry (DXA), blood draw, 7-day accelerometry, self-paced walking test, and balance test.

METHODS

The e-health platform was developed.

INTERVENTION

during Week 1, participants received a pedometer and a personalized consultation with a dietitian and an exercise physiologist. For 12 weeks, participants logged on to the e-health Web site to access personal step goals, nutrition education videos, and a discussion board. Follow-up occurred at Week 13.

RESULTS

Nine participants had a mean age of 67.5±6.7 years (60% women). Significant improvements were observed for fat mass (DXA), trunk fat mass, symptom severity (Swiss Symptom Scale), energy intake, maximum continuous activity (accelerometry), and mental health (SF-36) (p<.05). Nonsignificant improvements were observed for waist circumference, pain, ODI, and obesity biomarkers. Seventy percent lost weight, 50% increased walking capacity, and 60% increased quality of life. The mean increase in steps was 15%.

CONCLUSIONS

The spinal stenosis pedometer and nutrition lifestyle intervention was shown to be feasible, attractive to participants, and effective in this small sample. This intervention provides people with LSS the opportunity to participate in their own health management, potentially improving access to care. Efficacy is currently being assessed in a randomized trial.
