Implications of Arm Restraint on Lower Extremity Kinetics During Gait

Background Literature indicates the importance of the upper extremities in providing stability and propulsion for the body during ambulation. However, the kinetic implications of upper extremity restraint during gait are not as well documented. Aim The objective of this study was to examine the effect of arm restraint (unilateral and bilateral) on lower extremity joint kinetics during walking. Methods Twenty-three healthy young participants were instrumented for three dimensional motion analysis, and tested in four randomly ordered upper extremity restraint conditions (unrestrained, bilateral restraint, right side restraint, and left side restraint). Temporal spatial parameters and gait/phase-specific lower extremity kinetics and kinematics were measured. For each restraint condition, pointwise differences from the unrestrained condition were compared using a two-way ANOVA model of restraint condition (“Condition”) and gait cycle phase (“Timing”). Results Decreases in walking speed and stride length were observed for all restraint conditions. Differences in kinetic demands were also noted, primarily at the hip and knee. Conclusion Upper extremity restraint in healthy young adults leads to significant changes in temporal-spatial parameters and proximal joint kinetics, most prominently during periods of load accommodation and balance

AN IMMEDIATE FIT AND ADJUSTABLE TRANSTIBIAL PROSTHETIC SYSTEM; A PROSPECTIVE FEASIBILITY AND EFFICACY STUDY

INTRODUCTION Limb loss rates globally are rising and there is a large unmet need for an affordable and accessible prosthetic system for this growing US and International population.  The purpose of this prospective cohort study was to assess the feasibility and utility of a novel immediate fit modular prosthetic system (IFIT Prosthetics, LLC™ prosthesis) for transtibial amputees.
