Yoga Empowers Seniors Study (YESS)

November 14, 2016 updated by: George Salem, University of Southern California

Safe and Effective Yoga Prescription of Seniors: Biomechanical Considerations

This is an Intervention Development Study (IDS) to quantify the physical demands (using biomechanical investigation) of a 2-phase (beginning & intermediate), 32-week yoga program designed for community-dwelling older adults. Additionally, the IDS will explore the adherence and adverse events of participation in the program. Data from the IDS will be used to develop evidenced-based yoga programs, which the investigators postulate will be associated with fewer musculoskeletal side effects compared to non-evidence based yoga programs. The investigators also postulate that evidenced-based tailoring of yoga for seniors will enhance adherence and efficacy. The programs developed during this IDS will be tested in an expanded, Phase II, Randomized Controlled Trial.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Yoga is currently being recommended to restore and preserve strength, flexibility, balance, & physical capacity in older adults; however, our clinical trial experiences suggest that without proper evidenced-based prescription, Yoga participation can be ineffective or even injurious for seniors. To address this lack of evidence-based knowledge, the proposed IDS will: 1) quantify the physical demands of a 32-wk Yoga program designed for independent ambulatory seniors; 2) characterize the relations between these demands and participant physical characteristics; 3) examine the adherence, efficacy, & safety of the program; and 4) characterize the relations among reported adverse events, baseline participant characteristics, and Yoga physical demands.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
