1	Editor's Comments
	David A. Boone, CP, MPH, PhD
	The goal of this paper is to offer information on rehabilitation of amputees with traumatic brain injury in order to inform prosthetists primarily, and other healthcare practitioners secondarily, about techniques to be applied to this patient populat...

2	Infusing Cutting Edge Technology Into Everyday Orthotic and Prosthetic Clinical Care
	Ed Ayyappa, MS, CPO, FAAOP Dana Craig, BS, Eric Christensen, BS Heather Worden, BSME
	Advancements in temporal, kinematic, kinetic, metabolic, electromyography, and pressure data collection and an understanding of their impact have evolved from a perception of them as tentative tools of ambiguous value into a reality of tangible benef...

11	Functional Outcome of Transfemoral Amputees Fitted With an Osseointegrated Fixation: Temporal Gait Characteristics
	Laurent Frossard, PhD Kerstin Hagberg, PhD Eva Häggström, CPO David Lee Gow, MSc (Rehabilitation) Rickard Brånemark, PhD Mark Pearcy, PhD
	The purpose of this study was to characterize the functional outcome of 12 transfemoral amputees fitted with osseointegrated fixation using temporal gait characteristics. The objectives were a) to present the cadence, duration of gait cycle, support,...

21	Temporal and Spatial Parameters of Crawling in Children With Limb Loss: Implications on Prosthetic Knee Prescription
	Mark D. Geil, PhD Colleen Coulter-O'Berry, PhD, DPT, MS, PCS
	A prosthesis for children with limb loss at or above the knee must accomplish disparate goals when transitioning from crawling to walking: the mobility necessary for crawling and the stability necessary for standing and walking. This investigation te...

26	Differences in the Spatiotemporal Parameters of Transtibial and Transfemoral Amputee Gait
	M. Jason Highsmith, DPT, CP, FAAOP Brian W. Schulz, PhD, Stephanie Hart-Hughes, PT, MSMS, NCS Gail A. Latlief, DO, FAAPMR Sam L. Phillips, PhD, CP, FAAOP
	Transfemoral amputees are believed to have greater gait asymmetries than transtibial amputees, but this has not been clearly established. The purpose of this study was to determine the effects of amputation level on step length, width, and time for p...

31	The Lower Extremity Ambulation Feedback System for Analysis of Gait Asymmetries: Preliminary Design and Validation Results
	Stacy J. Morris Bamberg, ScD Randy J. Carson, DPT Gregory Stoddard, MPH Philip S. Dyer, MS Joseph B. Webster, MD
	Asymmetric gait impacts the metabolic cost of ambulation and the development of osteoarthritis and also affects the cosmetic appearance of gait. The Lower Extremity Ambulation Feedback System (LEAFS) is a shoe-insert device that uses force sensors to...

37	An External Shoe Modification for Reducing Metatarsal Head Pressure in People With Metatarsalgia
	James M. Hackney, PT, PhD Gary C. Hunt, PT, DPT, OCS, CPed Fred F. Lerche, PT, CPed Philip Voi, PT, CPed Judith W. Smith, MD, MBA
	One of the likely causes of metatarsalgia is repetitive high-pressure loading onto vulnerable metatarsal heads. This study investigated a shoe modification, the Hunt Metatarsal External Shoe Cut-out (HMESC), and its effectiveness in reducing pain and...

43	The Effect of a Talux® Prosthetic Foot on Gait Parameters and Limb Loading of Nonvascular Transtibial Amputees
	Terry Supan, CPO, FAAOP, FISPO Maria Lebiedowska, PhD Robert Dodson, CPO, BS, Steven Verhulst, PhD Michelle Dufour, BA
	The Talux® prosthetic foot is designed to combine the benefit provided by a dynamic response foot with the advantage of added dorsiflexion, plantarflexion, inversion, and eversion, thus closely simulating the normal human foot. This study aimed to: 1...

53	CASE REPORT: Multidimensional Motion of the Talux® Foot System in a Bilateral Transtibial Amputee
	Kirsten Tulchin, MS Don Cummings, CP, LP
	The State-of-the-Science Conference on Prosthetic Feet and Ankle Mechanisms in 2005 identified the application of multidimensional kinematic models as a future research priority in evaluating function in amputees. This case study provides an example ...

56	The Potential for Error With Use of Inverse Dynamic Calculations in Gait Analysis of Individuals With Lower Limb Loss: A Review of Model Selection and Assumptions
	Andrew B. Sawers, MSPO, CPO Michael E. Hahn, PhD
	Lower limb joint kinetics are among the most commonly reported values after instrumented gait analysis and are typically estimated via inverse dynamic calculations. In applying inverse dynamics calculations to a standard link-segment model, several a...

62	Clinimetric Properties of Timed Walking Events Among Patient Populations Commonly Encountered in Orthotic and Prosthetic Rehabilitation
	Phillip M. Stevens, MEd, CPO, FAAOP
	Many outcomes assessment measures involve timed ambulatory events and have been validated among those patient populations most commonly encountered in orthotic and prosthetic rehabilitation. These assessments are described, and the ranges of probable...
