Yoga to Prevent Mobility Limitations in Older Adults

Not Applicable

Completed

Conditions: Aging
Mobility Limitation
Sedentary Lifestyle

Interventions: Behavioral: Yoga Intervention
Behavioral: Healthy Aging Education

Registration Number: NCT03544879

Lead Sponsor: University of California, San Diego

Brief Summary: The loss of mobility during aging impacts independence and leads to further disability, morbidity, and reduced life expectancy. The study objective was to examine the feasibility and safety of conducting a randomized controlled trial of yoga for older adults at risk for mobility limitations. The investigators hypothesized that sedentary older adults could be recruited for the study, would attend either yoga or a health education control, would complete assessments, and that the interventions could be safely delivered.

Arm && Interventions

Group	Intervention	Description
Yoga	Yoga Intervention	The yoga intervention consisted of 2x weekly 60-minute sessions for 10 weeks. Yoga consists of postures, breathing exercises, movement, and meditation/concentration..
Health Education	Healthy Aging Education	The health education comparison intervention consisted of once weekly, 90-minute health information workshops conducted in group format. Sessions generally consisted of a 60-minute lecture followed by 30 minutes of questions and discussion.

Primary Outcome Measures

Name	Time	Method
Short Physical Performance Battery (SPPB)	Change in SPPB from baseline to 10 weeks	The Short Physical Performance Battery (SPPB) measures time to walk four meters; time to five chair stands; and balance, with higher scores being associated with decreased disability and mortality. These 3 components are rated on a scale from 0-4 and they are summed to provide a total SPPB score ranging from 0-12.

Secondary Outcome Measures

Name	Time	Method
Brief Anxiety Inventory (BAI)	Change from baseline to 10 weeks	Anxiety was assessed using the Brief Anxiety Inventory (BAI). The self-administered BAI consists of 21 items, and has well-established reliability(29) and validity. Scores can range from 0-63 with higher scores indicating greater levels of anxiety.
Step Up and Over (SUO)	Change from baseline to 10 weeks	The Step Up and Over (SUO) test measures gait quality as it may influence negotiating curbs, climbing or descending stairs, and predicting fall risk. The lift index quantifies the maximum lifting force exerted by the leading leg expressed as a percentage of the individual's weight as measured by the force plate, with scores closer to 100% demonstrating greater force.
Pittsburgh Sleep Quality Index (PSQI)	Change from baseline to 10 weeks	Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). The measure has 21 items and scores can range from 0-21 with higher scores indicating lower sleep quality.
Participant Satisfaction	10 weeks	Participant Satisfaction with participation was rated on a 0-10 scale (10 = most positive) usingquestions about enjoyment with and benefits of participation.
Rhythmic Weight Shift (RWS)	Change from baseline to 10 weeks	Rhythmic Weight Shift (RWS) measures participant ability to rhythmically move between two targets at different speeds. The On-Axis Velocity is the speed of the COG displacement in degrees per second during on-axis movement between the test target(s), with greater velocity indicating faster movement through the region of stability
Sensory Organization Test (SOT) Vestibular	Change from baseline to 10 weeks	The SOT assesses the sensory components of balance by measuring postural sway balance in different conditions as a useful predictor of fall risk. The ratio score indicates ability to maintain balance in the presence of inaccurate visual cues. Scores are represented as a percentage from 0 to 100, with scores closer to 100 indicating greater stability.
Limits of Stability (LOS)	Change from baseline to 10 weeks	The LOS is used to define a participant's "cone of stability" and measures components of balance and stability related to reaction time, directional control, and the ability to make corrective movements. Movement velocity indicates the speed of center of gravity (COG) displacement in degrees per second, with higher values signifying quicker movement through the region of stability.
SF-36	Change from baseline to 10 weeks	The SF-36 has 36 items and takes about 8-10 minutes to complete. The scale measure domains of health-related quality of life and two summary scores corresponding to physical and mental health. Scores for each subscale are standardized and range from 0-100 with higher scores representing better quality of life.
Center for Epidemiologic Studies Short Depression Scale (CES-D 10)	Change from baseline to 10 weeks	Depression was assessed using the 10-item Center for Epidemiologic Studies Short Depression Scale (CES-D 10). Scores can range from 0-30 with higher scores indicating higher levels of depressive symptoms.
Grip Strength	Change from baseline to 10 weeks	Grip Strength was assessed with an adjustable, hydraulic grip strength dynamometer.(26) The measure uses the average of two trials for both the left and right hand.
