STUDY DESIGN A randomized controlled trial. OBJECTIVES To assess the effectiveness of decompressive surgery as compared with nonoperative measures in the treatment of patients with lumbar spinal stenosis. SUMMARY OF BACKGROUND DATA No previous randomized trial has assessed the effectiveness of surgery in comparison with conservative treatment for spinal(More)
BACKGROUND Reliable normative data for force platform measurements of postural balance have not been available. METHODS Data on postural balance were collected from a representative nationwide sample of a Finnish population aged >or=30 years (n = 7,979). As part of a comprehensive health survey (Health 2000), postural balance was measured with the help of(More)
OBJECTIVES To examine long-term changes in handgrip strength and the factors predicting handgrip strength decline. DESIGN Longitudinal cohort study with 22 years of follow-up. SETTING Population-based Mini-Finland Health Examination Survey in Finland. PARTICIPANTS Nine hundred sixty-three men and women aged 30 to 73 at baseline. MEASUREMENTS(More)
AIMS The object of the present study was to acquire a comprehensive and accurate picture of mobility limitations in the Finnish adult population. METHODS A nationally representative sample of 8,028 persons aged 30+ with high participation was interviewed and examined in the Health 2000 Survey conducted in 2000-01. Mobility limitations were measured by(More)
BACKGROUND Age-related decline in muscle strength is among of the most important factors in the aging process leading to disability. This study examines age-related changes in handgrip strength through a 22-year follow-up in men and women. Because handgrip strength is associated with mortality, this study also accounts for the selection effect of right(More)
Transabdominal posterior rectopexy with resection of the redundant left colon (Frykman-Goldberg operation) was performed on 48 selected patients with complete rectal prolapse. Uterine suspension was also performed on most of the women. The 30-day mortality rate was 2.1%. Prolapse recurred in 4 (9%) of the 45 patients followed up for 1-10 (mean 4.3) years.(More)
In 31 adults consecutively undergoing surgery for anal fistula (opening of fistulous tract), anorectal manometry was performed before and 7 months after the operation. The resting pressure was significantly reduced in the distal 3 cm of the anal canal postoperatively. Voluntary sphincter contraction was less markedly affected. Maximal squeeze pressure and(More)
BACKGROUND AND AIMS Obesity among older persons is rapidly increasing, thus affecting their mobility negatively. The aim of this study was to examine the association of high body mass index (BMI) with walking limitation, and the effect of obesity-related diseases on this association. METHODS In a representative sample of the Finnish population of 55 years(More)
BACKGROUND In earlier studies, determinants of socioeconomic gradient in mobility have not been measured comprehensively. AIM To assess the contribution of chronic morbidity, obesity, smoking and physical workload to inequalities in mobility. METHODS This was a cross-sectional study on 2572 persons (76% of a nationally representative sample of the(More)
OBJECTIVES To determine optimal hand-grip strength cut points for likelihood of mobility limitation in older people and to study whether these cut points differ according to body mass index (BMI). DESIGN Cross-sectional analysis of data. SETTING Data collected in the Finnish population-based Health 2000 Survey. PARTICIPANTS One thousand eighty-four(More)
