Yoga Empowers Seniors Study (YESS)

14 novembre 2016 mis à jour par: 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.

Description détaillée

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.

La description

Inclusion Criteria:

  • Community dwelling men and women volunteers, aged 65 years or older.

Exclusion Criteria:

  • Safety exclusions:

    --the following safety exclusions are adopted in order to decrease potential *cardiovascular

    • musculoskeletal
    • neurological risks to the participants:
  • active angina
  • uncontrolled hypertension (SBP greater than 160 or DBP greater than 90)
  • high resting pulse or respiratory rate (HR >90 or RR>24 after 5 minutes seated)
  • unstable asthma or exacerbated COPD
  • cervical spine instability or other significant neck injury
  • rheumatoid arthritis
  • unstable ankle, knee, hip, shoulder, elbow, or wrist joints
  • hemiparesis or paraparesis
  • movement disorders (e.g. Parkinson's disease), peripheral neuropathies, stroke with residual deficits, severe vision or hearing problems
  • walker or wheelchair use
  • insufficient hearing to permit safety in a yoga group setting
  • not able to attend in-person classes
  • has not had check-up by regular provider within 12 months (if not taking any prescription medications) or in the past 6 months (if any regular medicines taken); cannot pass specific movement safety tests (tests described in section on screening visits, below)

  • Feasibility/adherence exclusions:

    1. unable to understand their commitment to the project, (laboratory visits & regular program participation)
    2. cognitive limitations significant enough to preclude informed consent or to raise concerns about participation safety

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
time to stand and sit from a chair 5 times
Délai: baseline, 16 and 32 weeks
In the 5-Repetition Chair Stand Test, we record the time it takes for a participant to repeatedly stand and sit on a chair 5 times.
baseline, 16 and 32 weeks
number of heel-rise repetitions
Délai: baseline, 16 and 32 weeks
The Heel-Rise Test is a measure of plantar-flexion endurance. Here, we record the number of full range-of-motion, heel-rise repetitions the participants can complete before fatigue.
baseline, 16 and 32 weeks
Time to complete Up & Go test
Délai: baseline, 16 and 32 weeks
In the Up & Go Test, a measure of mobility, we record the number of seconds it takes to rise from a chair, walk 8 feet, return and sit in the chair.
baseline, 16 and 32 weeks
Number of marching steps completed within 2 minutes
Délai: baseline, 16 and 32 weeks
In the 2-Minute Step Test, a measure stepping endurance, we record the number of complete marching steps the participant can perform within a 2-minute period
baseline, 16 and 32 weeks
Distance participant can reach forward from a sitting position
Délai: baseline, 16 and 32 weeks
