Comparison of Two Exercise Interventions to Improve Gait in Older Persons: The PRIME (Program to Improve Mobility in The Elderly) Study

The purpose of this research study is to compare two different exercise treatments for walking problems in older adults. The investigators want to determine if participation in the exercise programs for 3 months will improve walking abilities by improving balance and strength.

Detailed Description

The purpose of this research study is to compare two different exercise treatments for walking problems in older adults. We want to determine if participation in the exercise programs for 3 months will improve walking abilities by improving balance and strength.

Adults aged 65 years or older, who are able to walk without the help of another person, are being asked to participate. If you are able to walk independently and you have medical clearance from your physician to participate in activities requiring low to moderate physical activity, you are invited to participate. We plan to enroll 40 older adults, all who have small problems with walking due to balance or strength, in this research study.

Description

Inclusion Criteria:

  1. 65 years of age and older
  2. Ambulatory without an assistive device or the assistance of another person
  3. Usual 4 meter gait speed ≥1.0 m/s
  4. Completes a figure-of-eight walk in > 8.0 seconds

Exclusion Criteria:

  1. Inability to participate in testing:

    1. persistent lower extremity pain that is present on most days of the week and crepitus, tenderness or enlargement of joints of the lower extremity (arthritis).84
    2. back pain that is present on most days of the weeks and interferes with walking and activities of daily living or back pain that increases with walking (lumbar stenosis)
    3. calf pain or cramping which worsens with walking and is relieved by rest (PAD)
    4. refusal to walk on a treadmill

  2. Safety concerns:

    1. dyspnea at rest or during activities of daily living or use supplemental oxygen (CHF, COPD)
    2. any acute illness or medical condition that is not stable according to the approving physician
    3. resting systolic blood pressure ≥ 200 mm Hg or diastolic blood pressure ≥ 100 mm Hg or resting heart rate > 100 or < 40 beats per minute85
    4. diagnosed dementia or cognitive impairment defined as a MMSE score < 24
    5. hospitalized in the past 6 months for acute illness or surgery, other than minor surgical procedures
    6. severe visual impairment with visual acuity < 20/70 with best correction
    7. history of stroke
    8. fixed or fused lower extremity joints such as hip, knee or ankle
    9. lower extremity strength <4/5 on manual muscle testing
    10. lower extremity amputation
    11. progressive movement disorder such as MS, ALS or Parkinson's disease
