Lower limb motion handicap is one of the most common extremity diseases, which would lead to usage barrier for the patient physically and environmentally. The physical barrier includes imbalance, insufficient rigidity, poor loading capacity and walking abnormality. The environment one includes the height drop and usage of the lavatory. For the patient, the daily toilet usage equipment is the most troublesome in the lavatory in which the accidents occur most. Thus, this research aims at the medium mechanism of the human being, equipment, rehabilitation and environment, which develops the lower limb rehabilitation training equipment and barrier-free medium module.
This research is divided into 2 parts. Part 1 concerns with the『Development of Active and Passive Lower Limb Motor Control Rehabilitation Modality with Partial Weight Bearing and Barrier-free Environmental Adapted Modules』. The major WPA items are as below.
Give a clear definition of this research subject. Target the lower limb motion barrier patient to investigate his usage requirements and clinical assessment mode. Search and collect the specifications of the stand lift, walker and gait training device in market, proceeding with the patent material investigation. With the human body measuring database, we would carry on the measurement investigation of sitting posture and standing. Continuously, use QFD to formulate the custom-made requirement and system function specification. Sketch the concept design from the gained information, controlling the velocity adjustment of driving apparatus of this learning machine by the regulator voltage circuit.
Use Solid Works to carry on the detailed design of the active/passive mechanism of the driving apparatus of motor, and the detailed design of the partial supporting mechanism and rotation mechanism of the electric cylinder, and the detailed design of the orientation positioning mechanism of manual knob. Use COSMOS/works to proceed with the preliminary element analysis of the main frame, finding the most easily broken component. Proceed with the related Finite Element Analysis on this component, making the prototype and assemble it according to the sketch.
Carry on the loading capacity test of the supporting equipment with the counterweight of 20kg, 40kg, 60kg, 80kg and 100kg, recording the current in time. This lab would conduct the verification of standing and partial weight bearing, and the verification of moving back and forth/spinning/ striding left and right/active and passive walking. The Chung Shan medical university rehabilitation hospital and the Ren-Ai hospital are commissioned to use the foot pressure measuring system to carry on the clinical verification.
Part 2 concerns with the development『The barrier-free environmental adapted modules』to provide the lower limb motion patient with a household barrier-free lavatory environment, which includes the usage improvement of toilet, bathtub and hand washing bar, and the development of the Barrier-free Environmental Adapted Modules for barrier detecting. The major items are as below. Give a clear definition of this research subject. Carry on the specification investigation of the toilet apparatuses, proceeding with the concept design for each module. Use Solid Works to carry on the itemized module design of the major object as the lifting equipment of this rehabilitation learning machine, which includes the usage of toilet and hand washing bar, and includes the rotation of bathtub. Use COSMOS/works to analyze the bathtub rotation module, checking if there is any mechanism damage resulted from the lateral force of the rotation movement. With the photoelectric switch, it could make this module possessed of the mechanism for distance detecting and anti-collision. Integrate all the modules, assembling them. Carry on the function test and the clinical verification.
Having targeting on the lower limb motion patient, this research would not only develop the rehabilitation training equipment, but also further probe into the training mechanism of the left/right striding and active/passive walking originally. With the module design, it overcomes the inconvenience problems as the most troublesome usage of the toilet, bathtub and hand washing bar in the lavatory in which the accidents occur most. Thus, we provide the patient with a household barrier-free environment.
