The Effect of Microprocessor Controlled Prostheses on Walking Pattern and Energy Consumption

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to investigate MIC and non-MIC prostheses in terms of gait pattern and energy consumption in above-the-knee amputee patients.

Detailed Description
-----------------
Background: The use of microprocessor controlled (MIC) prostheses has increased in recent years, but the number of studies on gait pattern and energy consumption in above-the-knee amputee patients is very low. Objective: The aim of this study was to investigate MIC and non-MIC prostheses in terms of gait pattern and energy consumption in above-the-knee amputee patients. Methods: This observational clinical study included 34 unilateral above-the-knee amputees, separated into two groups as Group 1 (n:17) using MIC prosthesis, and Group 2 (n:17) using non-MIC prosthesis. The patients were compared in terms of gait pattern, gait capacity, energy consumption, mobility, quality of life, and prosthesis satisfaction levels according to the type of prosthesis. 3D gait analysis, exercise tolerance test, Short Form 36 (SF-36) Health Survey Questionnaire, Locomotor Capabilities Index-5 (LCI-5), Satisfaction with Prosthesis Questionnaire (SAT-PRO) and six-minute walk test (6MWT) were used as evaluation criteria.
