Opening Session/Thranhardt Lectures

The Opening Session of the 33rd Academy Annual Meeting & Scientific Symposium will take place in the Loews Metreon Theater. Highlights of this session include the two Thranhardt lectures Dermatological Problems with Prosthetic Roll-On Liners by Michelle Hall, CPO, FAAOP and Comparison of Measurements of Residual Limb Shape Using CAD versus Conventional Devices by Mark Geil, PhD. New additions to the Opening Session are the Selected Free Papers on Stance Control Knee Orthoses. Presenters leading this session are Gary Bedard, CO, FAAOP, Keith Smith, CO, LO, FAAOP and Kenton Kaufman, PhD.

Dermatological Problems with Prosthetic Roll-on Liners
Michelle Hall, CPO, FAAOP

Össur Kristinsson first developed the Icelandic roll-on silicone socket (ICEROSS) in the mid 1980’s. This type of socket interface was quickly popularized in the prosthetic community and has become the standard of treatment for transtibial amputees. Multiple manufacturers of roll-on liners, of various materials, now exist. These companies claim that liners offer superior comfort, suspension, and relief of dermatological problems compared to previous prosthetic options. A review of relevant literature reveals studies that are limited by the lack of diagnoses made by dermatologists and a failure to identify the frequency of these problems. Review results of a study designed to establish an incidence of dermatological problems in transtibial amputee subjects who utilize a roll-on liner with their prosthesis.

 

The measurement of standard residual limb anthropometrics such as circumference and anterior-posterior distance and understanding of fluctuations in limb volume and shape may become increasingly important with the need for outcome measures in prosthetic rehabilitation. Computer aided design and manufacturing (CAD/CAM) systems have been adapted for prosthetics for the primary function of socket design and fabrication. Review the results of this study that investigated an incremental step in that process: the capture and digitization of 3-D residual limb shape.

9:45 AM - 10:45 AM

Consider results of a study of a stance control knee ankle foot orthosis (SC_KAFO) that was fit to a 40-year old soldier who sustained a non-shrapnel concussive injury resulting in nerve root damage to left L3-5. The patient presented with an absence of proprioception and light touch with grossly 3/5 strength in the left lower extremity. All other extremities demonstrated normal function. Due to the severe proprioceptive loss the incidence of falling from knee buckling necessitated the use of a stabilizing orthosis.

 

Review results of a case study that presents the first reported use of Stance Control KAFOs in combination with an isocentric RGO in a patient with at T10 spinal cord injury. A comparison is made between the scenarios of having the knees locked during the entire gait cycle to that of allowing the knees to flex freely during the swing phase, yet still be locked for stability during stance.

Gait Changes Over Time in Stance Control Orthosis Users
Kenton Kaufman, PhD, PE

Test reports from several experimental stance control orthosis (SCO) systems have demonstrated a range of potential benefits. However, these reports have all studied subjects shortly after receiving their SCO. With one exception there are no reports in the literature that document gait changes over time. The objective of this report is to document the results of a prospective six-month open label clinical field trial of a novel SCO. We hypothesized that there would be improvements in gait over time.
