Brief Summary

Aims: Examine the effects of a community Tai Chi program on measures of balance and sensorimotor function. Methods: In a pre-test and post-test design, balance was measured in older adults (N=344; 73.4±7.4 years) with 30-second chair stand, timed-up and go, and 4-stage balance test following a 12-week community-based tai chi intervention. Balance measures and additional sensorimotor measures, including hip abductor electromechanical delay and hip proprioception, were measured in a smaller sample of older adults (n=11; 67.3±3.7 years).

Outcome Measures

Primary Outcomes (7)

  • 30-second chair number

    The number of times a person can stand up and sit down from a chair in 30 seconds

    12 weeks

  • Timed Up and Go

    The time (in seconds) for a person to stand from a chair, walk 10 feet, turn 180 degrees and return to sit in the chair

    12 weeks

  • 4 stage balance test

    How long (in seconds) can a person stand with feet together, stand with one foot forward and to the side, stand in tandem (one foot immediately in front of the other, and stand on one foot

    12 weeks

  • Hip abductor muscle contraction time

    Hip abductor muscle contraction speed as measured as the time (in milliseconds) between the onset of electromyography signal and torque onset from hip muscle abduction

    12 weeks

  • Brief-Balance Evaluation System Test

    The bBESTest is an 8-item, clinically-based assessment measuring anticipatory postural adjustments, compensatory postural responses, sensory orientation, stability in gait, and the timed up-and-go test.

    12 weeks

  • Activities-Specific Balance Confidence Scale (ABC) scale

    the ABC scale assesses self-reported confidence during 16 activities related to mobility.

    12 weeks

  • Hip joint proprioception error

    The magnitude of proprioception error was measured on the participant's dominant lower extremity with a custom-built device25,51 that allows for rotation around the axis of a semi-goniometer to measure proprioception in the transverse plane at the hip joint. Proprioception was assessed by measuring the accuracy of actively pointing a marked line on the second toe to target angles along the semi-goniometer during two conditions, a vision condition and an occluded vision condition.
