Initial Standing of the Osteogenesis Imperfecta Patient
Steve Baum, C.O.
Patricia Hazard, C.O.
Discussed is a design approach to a specific osteogenesis imperfecta case which was presented to Children's Hospital at Stanford Rehabilitation Engineering Center.
 
107
A Comparison of Current Biomechanical Terms
Susan Sienko Thomas, B.Sc.
Terry J. Supan, C.P.O.
The authors contrast the biomechanical terms used currently by prosthetists and orthotists and those used in the field of motion analysis. An understanding of biomechanics among prosthetists and orthotists can better provide patients with optimum tre...

CAD-CAM Applications for Spinal Orthotics -- Preliminary Investigation
Silvia U. Raschke, C.O.(c)
Margaret A. Bannon, B.Sc., M.Sc.
Carl G. Saunders, B.A.Sc., M. A. Sc.
William J. MeGuiness, C.P.O., (A,C), M.A.
The results of a study to determine the feasibility of applying existing CAD-CAM techniques to the design and manufacture of spinal orthoses are described.

A Foot Rotary Mechanism for the Modular Below-Knee Prosthesis
Al-Turaiki, M.H.S., B.Sc. (Hons). Ph.D.
The body's center of gravity is displaced anteriorly in the sitting position in many below-knee amputees fitted with PTB modular prostheses. The author incorporates a reliable foot rotator in this prosthesis to alleviate this and other problems exper...

Technical Note: Adding More Adjustability to the Hosmer VFJ-100 Vertical Fabricating Jig
Judd Lundt, B.S., A.E.
The authors modify prostheses using simple techniques and parts and equipment found in most prosthetic fabrication facilities.

Measurement of Plantar Pressure Using Fuji Prescale Film -- Preliminary Study
Gwen Ralphs
Thomas R. Lunsford, C.O.
Jack Greenfield, C.O.
The feasibility of using Fuji Prescale Film as a means of clinically assessing plantar pressure in a controlled group of subjects is described in this study.
 
139
A New Device for the Treatment of Metarsus Adductus
Andrew Chong, M.S., F.M.C.S.(c), F.A.C.S.
While the usual treatment of moderate to severe metatarsus adductus has been serial castings, a new device has been developed which may be used as an alternative to castings.

Myoelectric Hand Orthosis
Nisim Benjuya, Ph.D.
Steven B. Kenney, B.S.M.E.
A new myoelectric hand orthosis, primarily for the spinal cord injury patient at the C5-6 level, is developed. The device offers compatibility with the daily activities of the user without interference.
 
155
Hybrid Arm Orthosis
Nisim Benjuya, Ph.D.
Steven B. Kenney, B.S.M.E.
The researchers approach the problem of disabled arm motion and design a hybrid arm orthosis which offers body powered shoulder abduction and elbow flexion, motor-powered wrist supination, and a three-joint jaw chuck pinch.

Thermoplastic Elastomer (TPE) -- The TPE Ankle-Foot Orthosis and The TPE Biomechanical-Foot Orthosis
Ron Sutton, B.S.E., C.O.,
The author's research shows how the three components of walking are improved by the use of the TPE AFO.

Technical Note: Two in One KAFO
Robert A. Bangham, C.O.
The two in one KAFO design, which can be converted from a KAFO to an AFO and back again, solves a variety of problems faced by today's orthotists.
