138	Transfemoral Amputee Physiological Requirements: Comparisons Between SACH Foot Walking and Flex-Foot Walking
	Pamela A. Macfarlane, PhD David H. Nielson, PhD, PT Donald G. Shurr, MA, PT, CPO Kenneth G. Meier, CPO Rex Clark, MPT Janelle Kerns, MPT Michele Moreno, MPT Beth Ryan, MPT
	This article compares exercise intensity, oxygen uptake and gait efficiency when five active traumatic unilateral transfemoral amputees used a SACH foot versus a Flex-Foot attached below a hydraulic knee joint.

144	Mechanical Gait Analysis of Transfemoral Amputees: SACH Foot Versus the Flex-Foot
	Pamela A. Macfarlane, PhD David H. Nielson, PhD, PT Donald G. Shurr, MA, PT, CPO
	A companion to the first article in this issue, this article analyzes gaits of five active traumatic unilateral transfemoral amputees to explain the physiological benefits found when the subjects used a Flex-Foot compared to a SACH foot.

152	Metabolic Cost During Submaximal Walking With A Rigid Rotational-Control Ankle-Foot Orthosis: A Preliminary Investigation
	Janet S. Dufek, PHD John A. Mercer, MS Cheryl Sherwood Kosta, PT Deanna J. Fish, MS, CPO
	The authors evaluated the metabolic efficiency of walking with and without a rigid rotational-control ankle-foot orthosis by testing six volunteer patients walking on treadmills in braced and unbraced conditions.

157	Performance of a Continuously Sampling Hand-Held Digitizer for Residual-Limb Shape Measurement
	William M. Vannah, PhD David M. Drvaric, MD Joseph A. Stand III Jeffrey A. Hastings Janet E. Slocum, PhD David M. Harning, CPO George E. Gorton
	This article describes an alternative measurement method in which a hand-held digitizer is operated in a continuously sampling mode.

163	Pathology Forum: Characteristic Gait Patterns in Neuromuscular Pathologies
	Deanna J. Fish, MS, CPO
	The author reviews the characteristic gait patterns of six specific patient populations: muscular dystrophy, polio and flaccid paralysis, cerebrovascular accident and hemiplegia, cerebral palsy and diplegia, spina bifida, and spinal cord injury.

168	Case Study Forum: Gait Comparison of Two Prosthetic Knee Units
	Jeffrey L. Sutherland, CO David H. Sutherland, MD Kenton R. Kaufman, PhD Michael Teel, CPO
	The authors compare the gait characteristics of a single transfemoral amputee using two prosthetic knee units: the Total Knee and the DAW 4Bar pneumatic knee.

174	International Forum: Development of a New Ankle-Foot Orthosis with Dorsiflexion Assist, Part 1: Desirable Characteristics of Ankle-Foot Orthoses for Hemiplegic Patients
	Sumiko Yamamoto, PhD Masahiko Ebina Shinji Miyazaki, PhD Hideo Kawai Toshio Kubota, MD
	The development of an experimental ankle-foot orthosis that allows for easy adjustment of the magnitude of the assist moments and the initial ankle angle is described.
