Feasibility of Telephone Counseling to Increase Physical Fitness in SCI

2017年5月2日 更新者：Charles Bombardier、University of Washington

Feasibility of Telephone Counseling to Increase Physical Fitness in SCI (Co-Motion Study)

People with spinal cord injuries (SCI) are among the least physically active groups in our society. Approximately 1 in 4 healthy young persons with spinal cord injury (SCI) does not have sufficient fitness to perform many essential activities of daily living. About 50% of people with SCI engage in no leisure time physical activity. That is, they do not wheel or walk for pleasure, don't play a sport, don't exercise at home or go to a gym. As a result of this, cardiovascular, endocrine and metabolic conditions adversely affect the health of a large segment of the SCI population. Fortunately, clinic and/or laboratory-based aerobic conditioning and circuit training studies provide compelling evidence that people with SCI can improve their cardiorespiratory fitness and by doing so can partially reverse cardiovascular disease (CVD) risk factors, enhance Quality of Life (QOL) and improve elements of subjective well-being. While intensive, clinic-based, supervised exercise programs can improve the fitness and health of persons with SCI, the value of these findings for the SCI population is limited because the vast majority of people do not have access to these specialized programs and facilities. The gap that the present study addresses is: How can we extend the benefits of increased exercise and physical activity to more people with SCI?

The goal of this study is to evaluate the feasibility of an individually tailored, home- or community-based, telephone delivered intervention that uses evidence-based behavioral and motivational counseling to increase daily physical activity and exercise.

詳細な説明

The study is a randomized controlled trial comparing a 16 session telephone intervention aiming to increase physical activity to usual care.

Participants who agree to join the study and meet all eligibility criteria will be asked to do for following things in the course of 6 months.

BASELINE ASSESSMENT (Part 1 and 2):

For all participants who meet all screening eligibility criteria, a two-part baseline assessment will be scheduled at the University of Washington Medical Center Clinical Research Center.

During Part 1 of this visit, participants will complete an interview, medical tests and receive a DXA scan. After completing Part 1 of the baseline, participants will be given an activity monitor to wear at home for up to one week.

Approximately seven days after completing Part 1 of the baseline, participants will complete Part 2. Part 2 consists of a cardiorespiratory fitness test. A healthcare monitor will be available throughout testing to help ensure safety.

POST BASELINE FOLLOW-UP:

There are 3 possible outcomes following the baseline assessment.

  1. Individuals may not be eligible for the study because of a medical condition that needs treatment (for example, diabetes or hypertension).

    Individuals who qualify for the study will be randomized (like flipping a coin) to either a usual care group or the physical activity intervention group. Participants have an equal chance of ending up in either group.

  2. Participants may be randomized into the usual care group and receive no physical activity coaching by telephone.
  3. Participants may be randomized into the physical activity coaching intervention group. The physical activity coach will contact participants within one week to begin the 6 month intervention.

2 AND 4 MONTH ASSESSMENT (10 minutes):

All participants, regardless of group assignment, will be asked to complete telephone interviews with the research team two and four months after completing the baseline. Interviews will consist of questions regarding physical activity levels and barriers related to exercise.

6-MONTH OUTCOME ASSESSMENT (Part 1 and 2):

After six months, all participants will be asked to return to the University of Washington Medical Center Clinical Research Center to complete the 6-month outcome assessment. The 6-month outcome assessment will be identical to the baseline assessment.

During Part 1 of this visit, participants will complete an interview, medical tests and a DXA scan. After completing Part 1 of the 6-month outcome assessment, participants will be given an activity monitor to wear at home for up to one week.

Approximately seven days after completing Part 1 of the 6-month outcome assessment, participants will complete Part 2. During Part 2 of the visit, participants will undergo a cardiorespiratory fitness test. A healthcare monitor will be available throughout testing to help ensure safety.

  • Electrocardiographic abnormalities detected during any exercise test: 2o or 3o AV block, pre-excitation arrhythmia, hemi-blocks, S-T segment depression (horizontal, down sloping, or up sloping) diagnostic of myocardial ischemia, or other restrictions (ACSM Guidelines 7th Edition).
  • Current use of the following medications: Lipid lowering agents (e.g., statins, fibric acid derivatives, niacins, bile-acid sequestrates, or cholesterol uptake blockers), antihyperglycemics (biguanides, sulfonyureas, incretins, TZDs), herbal medicines and hyper-vitamins having antilipemic or antihyperglycemic properties, antihypertensives (Carbonic Anhydrase Inhibitors, thiazides, or loop diuretics), and estrogen replacement therapy.
  • Anticipated reasons subjects may be discharged from the trial and/or referred for medical therapy (if indicated): At the 6 month assessment subject laboratory values indicate they require medical treatment for diabetes, hyperlipidemia or hypertension; pregnancy; pressure ulcer that affects the safety of performing physical activity. NCEP ATP Guidelines will serve as the criterion for need for lipid intervention, ADA guidelines for diabetes, and JNC VII Guidelines for Hypertension

介入・治療
アクティブコンパレータ：Physical Activity Counseling
Participants who are randomized to the physical activity counseling intervention group will work with a physical activity coach over the course of 6 months to come up with a physical activity program that works for each individual. Participants will have 16 phone calls and discuss goals and values, track physical activity, troubleshoot barriers, and work on keeping exercise interesting and motivating. Participants will also learn strategies for managing stress and battling unhelpful thoughts that may get in the way of activity. By the end of the intervention, the goal is to be regularly doing 150 minutes of physical activity each week. The physical activity coach will work with participants to ensure that they are increasing activity safely in order to prevent injuries.
行動：Physical Activity Counseling
Participants in the physical activity counseling group will be mailed a home exercise toolkit that may include an activity monitor, exercise resistance bands, and exercise DVDs made for people with paraplegia or tetraplegia.
介入なし：Usual Care
Participants randomized to the usual care control group will receive a packet of exercise related-information at the end of the baseline assessment as well as a letter from study staff informing them of their randomization status and their test results. The letter will provide information on biological markers that are in the at-risk range, advice to seek medical advice regarding lifestyle changes such as diet and exercise and information on how to contact study staff regarding test results. We will offer to forward test results to their health care provider provided they furnish written release of information We will emphasize our interest in providing them with a follow-up assessment in 6 months.

Fat and lean body mass by dual energy x-ray absorotiometry (DXA)
時間枠：Baseline and 6 months post randomization
The procedure consists of the subject lying down on the machine for about 6-12 minutes with a low dose x-ray. The procedure is totally painless. The subject breathes normally but should remain still. The radiation is lower than a cross-country flight. Subjects should wear clothing with no metal, zippers, or buttons. All jewelry should be removed. DXA scans use a very low level of x-ray consisting of two different beams. One is a higher energy beam, while the other is a lower intensity. The lower intensity beam is only absorbed by soft tissue (muscle and fat), where as the higher intensity beam gets absorbed both by bones and by soft tissue. These differences in absorption are used to determine bone mineral density (BMD) and body composition values.
