  • Ages 18 to 100 years
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Diagnosed with histologically confirmed prostate cancer (confirmed by self-report on Health History Questionnaire. In the case a participant isn't able to confirm this criterion, a letter will be sent to his physician.)
  • Currently on ADT for >= 6 months OR not currently receiving ADT, but received >= 6-month course within the last 10 years (confirmed by self-report on Health History Questionnaire. In the case a participant isn't able to confirm this criterion, a letter will be sent to his physician.)

About this study

Official title: Group Exercise Training for Fall Prevention and Functional Improvements During and After Treatment for Prostate Cancer

The GET FIT Prostate trial (Group Exercise Training for Fall prevention and functional Improvements during and after Treatment for Prostate cancer) is a single-blind, parallel group, randomized controlled trial comparing - 1) tai ji quan (functional balance) and 2) strength training (functional strength) against each other and vs. 3) a stretching control (functional mobility) - over a 6-mos. supervised intervention and 6-mos. follow-up. Two million prostate cancer survivors are alive in the U.S. and nearly half (45%) will receive androgen deprivation therapy (ADT) to reduce tumor androgen exposure and slow down cancer progression. While beneficial for cancer survival, significant treatment-induced side effects from ADT may lead to serious health consequences including falls, frailty, and dysfunction that contribute to morbidity and mortality

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine and compare the efficacy of tai ji quan training and strength training in reducing the incidence of falls in prostate cancer survivors on antiandrogen therapy (ADT).

SECONDARY OBJECTIVE:

  1. To determine and compare the efficacy of tai ji quan training and strength training to reduce frailty and dysfunction in prostate cancer survivors on ADT.

TERTIARY OBJECTIVE:

  1. To determine how well the benefits of tai ji quan and strength interventions persist over a 6-month period.

EXPLORATORY OBJECTIVE:

  1. To explore the patterns and predictors of types of men (including host and treatment factors) who benefit most from tai ji quan and strength training.

OUTLINE:

The study is a 3-group, single-blind, parallel design randomized controlled trial in prostate cancer survivors treated with ADT. Participants in each study group will attend supervised 1-hr classes, 3 days a week for 6 months.

ARM 1: Tai ji quan, an integrated exercise routine consisting of 8 purposeful movement forms and a set of therapeutic movements, specifically designed to challenge limits of stability and train gait patterns, as reflected in movements such as upright trunk positioning, displacement of body's center of mass over the weight-bearing leg, and step initiation, locomotion, and termination.

ARM 2: Strength training. Participants wear a weighted vest while performing exercises using functional movement patterns that challenge balance by using muscle groups and movement involved in everyday activities (chair rises, 90°squats, side-to-side squats, toe raises, lunges (forward, lateral, backward, walking), multi-directional step ups).

ARM 3: Stretching control. Participants in the control group will attend a supervised flexibility program of the same total weekly duration as the experimental arms (e.g., 3, 60-min sessions per week). Control participants will perform a series of whole body stretching exercises, according to the ACSM guidelines for flexibility training, with a focus on developing and maintaining a healthy back.

Six Month Follow-Up: Participants will be followed for an additional 6 months after the 6-month supervised intervention stops to track falls (using same monthly report used during intervention phase). Exercise questionnaires to track participation in home or community exercise programs and will be collected at the 9- and 12-month time periods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Falls

    Prospective assessment of falls will be done by collecting monthly reports returned by postal and/or electronic mail. A fall is defined as unintentionally coming to rest on the ground or at some other lower level, not as a result of a major intrinsic event (e.g., stroke or syncope) or overwhelming hazard.

    Measured: Baseline up to 6 months

Secondary outcomes (11)
  1. Change in Total Frailty Score

    Frailty will be measured using the components of the Frailty Phenotype, which consist of measures of lean body mass, fatigue, physical activity, walk speed, and muscle strength, listed as additional outcomes below. Each component of frailty is assessed using measures that will capture frailty criteria in the prostate cancer survivor population using appropriate cutoff scores indicating that a component meets a particular criterion. A total frailty score was calculated for each patient at each timepoint defined as a count of the number of frailty components met.

    Measured: Baseline up to 12 months

  2. Lean Body Mass

    Lean body mass will be measured by bioelectric impedance analysis (in kg). Higher values indicate higher lean body mass.

    Measured: Baseline up to 12 months

  3. Fatigue-general

    Fatigue will be measured using the Short Form (SF)-36 Vitality scale. The scale ranges from 0-100 with lower scores indicating higher fatigue (i.e., less vitality).

    Measured: Baseline up to 12 months

  4. Fatigue-cancer

    Fatigue will also be measured using the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F). The questionnaire includes 13 items rated from "not at all" to "very much" over the past 7 days, and possible scores from 0 to 52. Lower scores indicate more fatigue, while higher scores indicate less severe fatigue.

    Measured: Baseline up to 12 months

  5. Physical Activity

    Physical activity will be measured by physical activity-related energy expenditure (kcals/week) calculated from self-report moderate-to-vigorous physical activity (MVPA). Lower scores indicate less MVPA and higher scores indicate more MVPA.

    Measured: Baseline up to 12 months

  6. Walk Speed

    Walk speed will be measured by the 3-meter Timed Up and Go, a widely used clinical measure of functional mobility that evaluates the time it takes to rise from a chair, walk 3m, turn around, and return and sit in the chair.

    Measured: Baseline up to 12 months

  7. Muscle Strength

    Muscle strength will be measured by timed chair stand test (seconds required to rise from chair 5 times). The larger the time, the longer it took them to complete 5 chair stands.

    Measured: Baseline up to 12 months

  8. Change in Functional Mobility

    Functional mobility will be measured by the Timed Up and Go (TUG) test which measures the time that it takes a person to rise from a chair, walk 7 meters (m), turn around a cone and return and sit in the chair. Larger times means they were slower, and shorter times mean they were faster.

    Measured: Baseline up to 12 months

  9. Change in Functional Balance

    Functional balance will be measured by postural sway which evaluates how well a person can maintain their equilibrium during quiet standing. Participants will perform a standard 30-second postural sway test to measure the velocity (meters per second [m/s]) of sway during quiet standing with feet together and eyes closed using lightweight, inertial wireless sensors worn on the trunk. Lower sway velocity (m/s) indicates better postural stability.

    Measured: Baseline up to 12 months

  10. Change in Perceived Physical Function

    Perceived physical function will be measured by self-report using the physical function subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30; version 3, App. I). Scores on the subscale range from 0-100 where higher scores indicate better physical functioning.

    Measured: Baseline up to 12 months

  11. Flexibility

    Flexibility will be measured using the chair sit and reach. While seated on the edge of a chair, participants bend from the hip and reach toward or past the toes. The toes represent 0, so a reach short of the toes is recorded in negative inches, and a reach past the toes is recorded in positive inches. Higher negative values indicate greater flexibility.

    Measured: Baseline up to 12 months
