NCT06108713

Brief Summary

The purpose of the study is to verify the effect of juggling exercises on selected cognitive functions (reaction time, attention) and postural stability variabilities (based on center of pressure signal) in two different protocols: \[1\] a randomised crossover study design, \[2\] a randomised repeated measurement design.

Outcome Measures

Primary Outcomes (10)

  • Velocity of center of pressure assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Velocity of center of pressure will be presented in centimeters per seconds.

    Assessment of the velocity of center of pressure will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Area 95 percentile assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Area 95 percentile will be presented in square centimetres.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Medio-lateral range of sway assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Medio-lateral range of sway will be presented in centimeters.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Anterior-posterior range of sway assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Anterior-posterior range of sway will be presented in centimeters.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Effective value of medio-lateral velocity assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Effective value of medio-lateral velocity of sway will be presented in centimeters per seconds.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Effective value of anterior-posterior velocity assessed with AMTI force plate

    Postural stability variable based on center of pressure signal. Effective value of anterior-posterior velocity of sway will be presented in centimeters per seconds.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Absolute error of elbow joint position accuracy assessed with electrogoniometers

    Proprioception ability. Measured in degrees of flexion.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Variable error of elbow joint position accuracy assessed with electrogoniometers

    Proprioception ability. Measured in degrees of flexion.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Constant error of elbow joint position accuracy assessed with electrogoniometers

    Proprioception ability. Measured in degrees of flexion.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Root mean square error of elbow joint position accuracy assessed with electrogoniometers

    Proprioception ability. Measured in degrees of flexion.

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

Secondary Outcomes (9)

  • Simple reaction time assessed with reaction time test in Vienna Test System

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Complex reaction time assessed with reaction time test in Vienna Test System

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Decision time assessed with reaction time test in Vienna Test System

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Motor time assessed with reaction time test in Vienna Test System

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.

  • Time of correct rejections assessed with cognitrone test in Vienna Test System

    Assessment will be carried out up to three days before juggling/no juggling periods, and also up to three days after juggling/no juggling periods. Measurements will be taken at a total of four time points.
