Ataxia-ball bouncing (D8)

AIM:

To improve the temporal accuracy of open tasks which require predictive timing (bouncing a ball)

Rationale:

Modified task practice (rolling a ball along a table and bouncing off the wall) is performed to promote appropriate timing and accuracy. Progress to whole task practice.

Equipment:

  • Table
  • 2 chairs
  • Wall
  • Ball
  • Tape to use as a target
  • Barriers to prevent ball from rolling off the table

Key Points:

  • Ensure patient is sitting upright with the feet supported on the floor
  • Ensure timing is promoted by practicing sequential ball tapping, ie, no pause between taps

Common Errors:

  • Patient supports the arm/s on the table
  • The magnitude and/or direction of force used when tapping the ball is inappropriate

Progression and Variety:

  • Tap the ball closer to the wall
  • Use a smaller ball
  • Decrease the size of the target
  • Vary direction
  • Remove the table and tap the ball back and forth between both hands and/or repetitively tapping the ball into the air with the fingertips
  • Progress to bouncing the ball on the floor
