Battery Placement for a Long Residual Limb Consideration of battery placement is particularly important in longer sockets. The shape of the inner socket must also be considered.
  • Page 9 2.3 Charge Port Placement Assembly It is important to provide sufficient space for the charge port between the inner and outer sockets. The charge port should be positioned so that it is unaffected by forces running through the socket to prevent damage. Create a drill hole of 8.0mm through the inner surface of the prosthetic frame.
  • Page 10 2.4 Battery Options Two battery options are available for the i-limb ultra revolution, both of which have been specifically designed to meet the power requirements of the hand. Battery selection should be based on available space within the socket fabrication, shape of the residual limb and the expected level of use.

  • Page 39 Additional Features Toward the bottom right of the screen the additional Global Options box can be used to give access to Vari-grip / pulsing, Natural Hand, Auto-grasp modes, and rotate thumb on exit. Vari-grip/pulsing: this mode provides additional grip force when the closed signal is sustained for the amount of time selected (default 0.5 seconds).
  • Page 40 Natural Hand: this feature returns each digit to a position which can be preset by the user. The default setting for activation is 30 seconds, this can be customized between 2 and 60 seconds. Auto-grasp: this feature enables the user to counter a false open signal during grasping.
  • Page 41 Co-contraction is the creation of quick simultaneous open and closed signals. Co-contraction may be customized if a patient has difficulty with activation within the default time. The default detect time is set at 80ms and can be customized between 10 and 250ms. Require Stall Open: You have the option to require a hold open before a co-contraction can be detected.
  • Page 42 Step 2: Perform co-contraction to get 4 successful attempts. Step 3: After 4 successful attempts, biosim tells you the value and will automatically update i-limb ultra revolution. Double impulse (two quick uninterrupted open signals) the impulse duration is the period of time that the impulse is above the threshold.
  • Page 43 Step 2: Perform impulses to get 4 successful attempts. Step 3: After 4 successful attempts, biosim tells you the value and will automatically update i-limb ultra revolution. The graph shows a failed double impulse attempt. The double open signals are strong and within the preset impulse period, however the presence of the blue, closed impulse disrupts the signal.
  • Page 44 The graph shows a failed double impulse attempt. The double open signals are sufficiently strong, however the impulses are too far apart to be identified as one signal. Both impulses are recog- nised as individual open signals. Encourage the patient to activate their muscle signals closer together, with less relaxation time between each impulse.
  • Page 45 6.3.4 Training The training suite contains a variety of short training exercises aimed at developing control of the i-limb ultra revolution. The opening screen highlights the series of exercises which can be selected individually and in any order. Both open and closed signals can be practiced.

Speed Only focuses on generating quick, strong muscle signals. Do not be concerned about the opposing muscle in this exercise. Strength and Separation focuses on generating a smooth, strong muscle signal while isolating the opposing muscle.
