Yoga decreases kyphosis in senior women and men with adult-onset hyperkyphosis: results of a randomized controlled trial.

ABSTRACT: To assess whether a specifically designed yoga intervention can reduce hyperkyphosis.A 6-month, two-group, randomized, controlled, single-masked trial.Community research unit.One hundred eighteen women and men aged 60 and older with a kyphosis angle of 40 degrees or greater. Major exclusions were serious medical comorbidity, use of assistive device, inability to hear or see adequately for participation, and inability to pass a physical safety screen.The active treatment group attended hour-long yoga classes 3 days per week for 24 weeks. The control group attended a monthly luncheon and seminar and received mailings.Primary outcomes were change (baseline to 6 months) in Debrunner kyphometer-assessed kyphosis angle, standing height, timed chair stands, functional reach, and walking speed. Secondary outcomes were change in kyphosis index, flexicurve kyphosis angle, Rancho Bernardo Blocks posture assessment, and health-related quality of life (HRQOL).Compared with control participants, participants randomized to yoga experienced a 4.4% improvement in flexicurve kyphosis angle (P=.006) and a 5% improvement in kyphosis index (P=.004). The intervention did not result in statistically significant improvement in Debrunner kyphometer angle, measured physical performance, or self-assessed HRQOL (each P>.1).The decrease in flexicurve kyphosis angle in the yoga treatment group shows that hyperkyphosis is remediable, a critical first step in the pathway to treating or preventing this condition. Larger, more-definitive studies of yoga or other interventions for hyperkyphosis should be considered. Targeting individuals with more-malleable spines and using longitudinally precise measures of kyphosis could strengthen the treatment effect.

Project description:IntroductionHyperkyphosis commonly affects older people but is not widely acknowledged as a clinically actionable problem, especially in men. There are several techniques to quantify kyphosis including the blocks and Cobb angle measurements. This study includes both kyphosis measures to investigate whether older men with accentuated kyphosis may be at increased mortality risk.MethodsMen aged ≥65 years (N = 5994) were recruited to participate in the MrOS prospective cohort study from 2000 to 2002 (baseline). Our primary cohort included 2931 enrollees (mean age 79.3 years; SD 5.2) who underwent blocks-measured kyphosis from 2006 to 2009. Our secondary cohort included 2351 participants who underwent radiographic Cobb angle measurements at baseline. Cox proportional hazards analyses were used to determine association between kyphosis and all-cause mortality while adjusting for prevalent radiographic vertebral fractures, bone mineral density, incident fractures, gait speed, timed chair stands, self-reported health, alcohol use, medical co-morbidities, and physical activity.ResultsDuring a mean follow-up of 8.3 (SD 3.2) years, 1393 participants died in the primary cohort. In this group, compared to men with 0-1 block kyphosis, increasing blocks-measured kyphosis was associated with increased mortality (HR: 1.26-1.53, p trend <0.001). With addition of prevalent vertebral fracture to adjusted models, the association remained significant in participants with severe kyphosis (3+ blocks-measured). Similarly, with addition of chair stand performance the association remained significant for 4+ blocks kyphosis. Walking speed did not attenuate the association of kyphosis and mortality. In the secondary cohort, there were no significant associations between radiographic Cobb angle kyphosis and mortality.ConclusionsIncreasing blocks-measured kyphosis was associated with a greater risk of mortality in older men, indicating that hyperkyphosis identified on physical exam should be considered a clinically significant finding that may warrant further evaluation and treatment.
