Comparing the Effectiveness of Various Interventions on Improving Lumbar Proprioception
Condition: Proprioception
Study type: Interventional

Summary: 
      University students ages 18-45, with no recent history of back injury and no history of back
      surgery, were recruited. Participants completed proprioception testing consisting of a
      standing side bending and seated spinal flexion test. Participants performed each test once,
      then were blindfolded and asked to replicate the tests 10 times. After the initial
      proprioceptive testing, the participants were randomly split into four groups and performed a
      10-minute intervention exercise, before repeating the proprioceptive tests for final
      measurements. The four groups included: graded motor imagery, mirror visual feedback,
      augmented biofeedback, and diaphragmatic breathing. Participants also completed a Physical
      Activity Enjoyment Scale to rate their enjoyment of their intervention task

      -For the seated forward flexion test, the participants' C7 and S2 vertebrae were identified
      and used as markers. The participants were asked to bend forward until the tape measure
      increased 5 cm from the original distance between the C7 and S2 vertebrae. Similar to the
      seated flexion test, during the side-bending task, the participants were asked to side bend
      until the tip of their middle finger was 10 cm closer to the floor. The participants were
      asked to memorize that point in their mind; they were then blindfolded and asked to repeat
      the movement 10 times, trying to recreate the original position to the best of their ability.

      Between initial and final measurements of proprioception, the participants were randomly
      assigned to one of the following four groups for interventions for a 10-minute training
      session:

        -  Graded Motor Imagery Group: Participants were shown several flashcards with pictures of
           individuals' back oriented to either the flexed or side bent position. The participants
           stated which direction the image depicted and visualized themselves making the movement
           identified in the picture.

        -  Mirror Visual Feedback Group:

      Participants viewed themselves in a mirror while performing flexion and side bending
      movements.

      -Augmented Biofeedback Group: Participants used an augmented musculoskeletal feedback system
      smartphone application app and small sensors with Bluetooth technology to translate the
      movement of the participant into an avatar on the game.

      -Diaphragmatic Breathing Group: Participants were told to sit on a chair with their back
      straight and feet flat on the floor with one hand on their chest and one hand on their
      stomach. They performed diaphragmatic breathing in a slow 4 second box method: breathing in
      for 4 seconds, holding for 4 seconds, breathing out for 4 seconds, and then hold for 4
      seconds
