Abstract— A Real-Time, Inexpensive Gait Analysis System that cost less than RM3,000 (= USD982) is proposed in this paper. The proposed system consists of subsystems such as wireless wearable accelerometer system, Custom-made force platform, data acquisition system with real-time computer data logging capability. Kinematics and kinetics parameters of human locomotion were collected and analysed by the system. The results collected were compared against published normative human gait data. Data collection was performed on 20 healthy test subjects without any reported gait-deflciency. 

There are numerous researches attributed to the development of insole-based system that collects various gait parameters seen in the literatures [7], [9] - [13], [22]. Most of the system proposed did not emphasis on the factor of costs in commercialization. Hence, the need of developing cost-effective instrumentation is necessary to cater the lower-income nations. In view of the latter, this paper proposes a cost-effective and affordable gait analysis system that costs less than RM3,000 ( USD892) [14],... 

The purpose of this stody is to measure and evaluate spatio-temporal parameters and the pressure data associated with the walk in normal cats using a new gait analysis system adapted for cat.

The developed system was an accurate, cost-effective and user friendly motion analysis system for basic human motion analysis. In addition, the proposed system could be used as start-up gait laboratory where fundamental kinematics and kinetics parameters of human gait are essential. Furthermore, the scope of application of such instrumentation is wide from clinical application of studying pathological gait, rehabilitation, sport science, and eventually to telemedicine and development of humanoid robot.

Data were collected at a gait analysis lab equipped with six infra-red Motion Analysis cameras (Vicon 460, Vicon Motion System Ltd., Oxford. UK) and two force plates (Kistler Instrument AG, Switzerland). Data were collected at a rate of 200 Hz. Markers were placed on anatomical landmarks according to the modified Helen Hayes marker set including Toe, Heel, Ankle, Tibia, knee, Thigh and Hip... 

Some strain gauges were attached on the lateral bar of the orthosis in order to measure the absolute values of the loads applied on the orthosis. The gait parameters and the loads applied on the hip joint and crutches were measure by motion analysis system.

The pressure walkway system also ealled pressure sensors system, most were designed to measure spatio-temporal gait analysis and built around pressure sensors included in a walkway. Data collection and analysis was performed by specific software. Pressure walkway was used recently in some research for humans [3], but still very little in animals such as dogs [4, 5], cats [1, 2], rat [6] and sheep [7]. 

Recently, a human gait analysis tools have introduced GAITRite system, a pressure mat, which measure spatio-temporal parameter, peak vertical pressure and velocity of walk. Combined with specialized qnadraped-adapted software, this system can calculate these parameters for each limb at the same time and in the same conditions at one walk. 

Studies recently assessed the concurrent validity of the GAITRite system in humans with video-based analysis system [9] paper-and-pencil and video-based methods [10] a footswitch system [1 Ij a three-dimensional motion analysis system Vicon-512 [12] and stopwatch-footfall count method [14], all of these reports demonstrated that the results of validity and reliability of this system for gait analysis were excellent. The same procedures had been done in dogs [20].
