Brief Summary:
The purpose of the study is to examine the short and long term effects of Hatha yoga compared to the current recommended exercise program in promoting physical function, alleviating osteoarthritis (OA)-related symptoms, fear of falling, and improving mood, spiritual health, physical activity level, and quality of life in older adults with knee OA, and to determine the effect sizes for use in power calculations to design a larger efficacy clinical trial.

Knee Osteoarthritis Other: Hatha yoga Other: Aerobic and strengthening exercises Other: General education Not Applicable

Detailed Description:

The specific aims of this pilot project are to:

Aim 1: Examine the short and long term effect of participation in an 8-week intervention of Hatha yoga (HY) on pain, stiffness, physical function of the lower extremities, physical activity, mood, fear of falling, spiritual health, and quality of life in older women with knee OA, compared with the effect in those older adults who participated in aerobic/strengthening exercise (AE) or received general OA education (GE).

Aim 2: Describe the adherence rate (class and home practices) and exercise acceptability of the HY and AE programs.

A randomized controlled trial design with three groups were used: 1) A Hatha yoga (HY) intervention group, 2) an aerobic and local muscle strengthening exercise (AE) control group, and 3) a general OA education (GE) true control group. Both yoga and exercise groups involved group and home practice sessions. Participants in the GE group received education on OA management after randomization. A weekly phone call were placed to them during the intervention period to reinforce OA knowledge. Data were collected from all participants at baseline, 4 weeks, and 8 weeks during the intervention, and quarterly for one year during the follow up period.

Study Endpoints

  1. Primary endpoint: OA status (pain, stiffness and function) at 8 weeks.
  2. Secondary endpoint: physical function of lower extremities, mood, and quality of life at 8 weeks.
  3. Tertiary endpoint: Long term exercise adherence and effects on outcome measures, program acceptability, and safety.

Sample Size and Recruitment Eight-three community dwelling older adults ages 60 years - 100 years old with a diagnosis of symptomatic knee OA were recruited. Recruitment were done through conducting presentations at various senior centers; distributing press release to various community newsletters, local and senior newspapers, and through working with my co-investigators, and accessing the data base and mailing invitation letters out to patients meeting demographic and diagnostic criteria from the University of Minnesota Physician Practice.

Each weekly group based session is 45 minute in length for all groups. Participants in the yoga group were recommended to practice for additional 30 minutes four times a week at home. Participants in the A/E class were recommended to practice 3 times on non-consecutive days at home as recommended by the current physical activity guidelines for older adults. To assist participants with maintaining exercise adherence and practicing yoga and aerobic/strengthening exercises at home correctly, handouts illustrating yoga/exercise activity were distributed at the end of each class. Participants also were asked to videotape and keep a log of their exercise practice during the intervention period. Video camera were provided. Long term exercise adherence was assessing using an exercise diary. Participants were asked to keep an exercise diary during the follow up period. A focus group will be conducted at the end of the follow-up period to examine the experience of using HY or AE for managing knee OA, and factors that affect participants' HY/AE adherence.

Descriptive statistics will be used to analyze and report demographic data and feasibility/acceptability data. Inferential statistics (t-test or non-parametric equivalent such as Mann-Whitney, and chi-square test) will be used to analyze the OA symptoms, physical and psychological outcomes. The α level will be set at ≤ .05.

Arm Intervention/treatment
Experimental: Yoga Group
Participants in the yoga group received a total of eight weekly 45 minute yoga classes. A sequence of 8 - 10 core yoga poses, breathing and relaxation techniques were practiced in each yoga class, and 2 - 3 new poses were introduced progressively in each of the yoga session. Props such as blocks, blankets, belts, mats, and chairs were used during the session. Handouts were provided for participants to practice the yoga program for additional 30 minutes a day, 4 days a week at home.
Other: Hatha yoga
A sequence of 8 - 10 core yoga poses, breathing and relaxation techniques were practiced in each yoga class, and 2 - 3 new poses were introduced progressively in each of the yoga session. Props such as blocks, blankets, belts, mats, and chairs were used during the session.
Other Name: Yoga

Active Comparator: Aerobic and Strengthening Exercise Group
Participants in the exercise group received a total of eight weekly 45 minute exercise classes. A 15 minute of gentle aerobic exercise and a 30 minute of strengthening program that includes both isometric (without moving the joints) and isotonic (moving the joints) exercises of the lower extremities were taught to the participants. Handouts were provided for participants to practice the program at home for 30 minutes a day, 3 days a week (on non-consecutive days).
Other: Aerobic and strengthening exercises
A 15 minute of gentle aerobic exercise and a 30 minute of strengthening program that includes both isometric (without moving the joints) and isotonic (moving the joints) exercises of the lower extremities were taught to the participants.

Active Comparator: General education
Participants in this group received a one-time OA educational brochures from the Arthritis Foundation including topics focusing on the disease process, diet and exercise and OA management education. Participants were instructed not to begin any new exercise programs during the study period.
Other: General education
One-time Arthritis Foundation educational brochures focusing on the disease process, diet and exercise and OA management education were given.




Primary Outcome Measures :
  1. Osteoarthritis (OA) symptoms change [ Time Frame: Change from baseline OA symtptoms at 8 weeks ]
    OA pain, stiffness and function (total score) is evaluated using the Western Ontario and McMaster Universities OA (WOMAC) index scale.

  2. Knee OA pain change [ Time Frame: Change from baseline pain score at 8 weeks ]
    Visual Analog Scale

  3. Knee OA pain change [ Time Frame: Change from baseline number of medication used per day for OA pain at 8 weeks ]
    Number of pain medication used per day for OA pain


Secondary Outcome Measures :
  1. Physical function [ Time Frame: 4 and 8 weeks ]
