Brock String – Near-Far Rock

May 17, 2013
by
DrB

The Brock String is the basis for some wonderful activities, helpful in developing visual skills. Brock Strings are used to:

  1. Create awareness of space and depth.
  2. Increase the range of motion of the eyes.
  3. Increase accuracy and range of targeting.
  4. Improve scanning ability.

Brock String — Near-Far Rock is very sim­i­lar to Basic Brock: Jumps Near Range with some impor­tant differences:

  • You are work­ing with both near and dis­tant tar­gets, that is, beads aligned in the near and far end of the string (between a few centimeters from the nose, i.e., the ‘break point’, and targets beyond about 40 cm). (See Bug On String for details on the Break Point.)
  • The client will still ‘jump’ from bead to bead in a reg­u­lar sequence (see Basic Brock: Jumps Near Range), but again, the tar­gets will be much more spread out: The near target will be at the break point, and the remaining beads will be spread more or less evenly across the remaining distance up to the 6-10 foot range, depending on the client’s restrictions.
  • The dou­bling of vision may not be as easy to per­ceive at some distances, so don’t worry if the child can­not ‘see’ the string dou­bling beyond a cer­tain dis­tance. The string and beads near the nose should still appear dou­bled out to the first bead if the bead is near enough. See Phys­i­o­log­i­cal Diplopia: When see­ing dou­ble is cor­rect.
  • Do not use a patch for this activ­ity unless directed to do so by your optometrist. For exam­ple, fix­at­ing a dis­tant object might be eas­ier for some stra­bis­mic child when one eye is occluded. Gen­er­ally, the patch should be avoided for most clients.

You should study all notes relating to Brock String activities prior to attempting them. Always follow the guidance of your vision care provider. Do not exceed what clients can comfortably tolerate.
