Walking aids are extensively used by elderly individuals to improve their stability and ambulatory ability. Despite their common usage and prolonged existence, the basic walker design still remained unchanged. To date, knowledge of biomechanical and functional requirements for the effective use of walker is still limited. Only few studies were conducted to address the changes in upper extremity kinetics while using a standard walker. In the present work, an instrumented walker is discussed theoretically and a new system is developed using the measurement of subject’s resultant arm upper extremity loads. The bilateral upper extremity kinematics and kinetics data were acquired through Visual3D motion analysis system. The internal joint force and moment for the wrist, elbow and shoulder were determined using inverse dynamics models. These data were collected from seven healthy subjects, right handed young adults and elderly. By utilizing these experimental data, a walker support system was developed based and verified the design using the same subjects through repeated experimentation.  Significant changes of resultant forces were observed for walker support system implementation.  Elbow joint moment was observed to be reduced with the implementation of support system.
