Brief Summary

The study hypothesized that it is feasible and safe to use Hatha yoga in older women with knee osteoarthritis (OA), and practicing Hatha yoga regularly will help reduce pain and stiffness, enhance physical function, and improve quality of sleep and quality of life in older women with knee OA.

Conditions

Osteoarthritis, Knee; Quality of Life; Poor Quality Sleep; Physical Impairment

Keywords

Yoga; Knee osteoarthritis; Symptom management; Older women; Pain; Stiffness; Physical function); Physical function of the lower extremities; Quality of sleep; Quality of life

Outcome Measures

Primary Outcomes (2)

• Absolute Value of OA Symptoms at 8 Weeks

  Primary outcome measures included: OA symptoms (pain, stiffness and function) were assessed using the Western Ontario and McMaster Universities OA Index scale (LK scale 3.1)(WOMAC). The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). A total WOMAC score is created by summing the items for all three subscales resulting in a possible score of 0 - 96. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

  8 weeks

• Absolute Value of OA Pain at 8 Weeks

  A single question that asked about the number of pain medications used per day for knee OA was also used to measure OA pain status.

Study Arms (2)

yoga intervention

EXPERIMENTAL

The yoga intervention received eight 60 minute weekly Hatha yoga intervention classes and asked to practice additional 30 minute yoga per day at home.

Behavioral: Hatha yoga

wait list control

OTHER

The wait list control group received the same 8-week Hatha yoga intervention involving group and home-based exercise sessions after the yoga intervention group completed the intervention at the end of 8 weeks.

Behavioral: Hatha Yoga

Interventions

Hatha Yoga BEHAVIORAL

Hatha yoga poses that were specifically designed by a group of yoga experts for older adults with knee osteoarthritis. Program included physical poses and sequence that focus on strengthening the lower extremities, and relaxation techniques.

Eligibility Criteria

• Age: 65 Years - 86 Years
• Sex: female
