“…According to a market survey, the cost is reduced to the achievable US $400 compared to a minimum US $1100 in the United States. Kim et al [8] developed a driving module attached to a manual wheelchair with an easy locking mechanism to assist persons with lower limb disabilities. The driving module was tested to evaluate its performance, and the results showed that the developed system helped increase the mobility of persons with lower limb disabilities.…”

This study introduces a cost-effective portable electric towing system designed by researchers to facilitate mobility for individuals with lower limb disabilities. The system enables users to supplement their standard wheelchairs with an electric towing mechanism, enhancing the ease of movement at an affordable price point. After the design and construction phase, the system was tested to ensure functionality and performance. Testing criteria included a minimum user weight of 80 kg and a driving distance of at least 20 km per charge. The driving tests, conducted five times, occurred at the Seeniare Complex, Bangkokthonburi University (Nursing and Public Health Practice Center). Testing started by navigating a 3.5-m radius curve from a 15-km distance, simulating regular road conditions. Subsequently, the system's ability to ascend a 1:12 gradient (in compliance with Thai accessibility standards) was evaluated. Additionally, the braking system was assessed to ensure that the electrically towed wheelchair could come to a static stop within a 10-m distance continuously along a 1:12 gradient without slipping or tipping. The results demonstrated compliance with specified standards on each occasion. Furthermore, cost comparison analysis with market-available electric wheelchairs revealed the lowest-priced towing system to be $382.16. User satisfaction evaluations indicated an overall satisfactory rating. This research underscores the potential of the developed electric towing system to significantly enhance mobility and independence for individuals with lower limb disabilities, offering a practical and cost-effective solution. Further studies and refinements could reinforce its efficacy and applicability in real-world scenarios, and upon analyzing the production costs, it can be seen that the towing kit developed is priced low, allowing people with low incomes to easily access assistive devices.

One of the causes of paralyses is stroke that occurs because of brain blood vessel disorder. Because of it, the patients suffered from stroke must lay most of their time on a bed. Laying too long can pressure a specific area in contact with the surface of the bed leading to decubitus. To prevent this, the nurse changes the patient's sleep position periodically. Most hospital beds have been designed to adjust the position of the patients. However, changing the bed position manually needs extra energy. The study aims to design a tool for hospital bed control using a DC motor controlled by a microcontroller. Nurses, patients and families of the patients can change the position of the bed by using a button connected to the microcontroller. The bed controller circuit uses the button to control the bed position using a dc motor. By using this device, the patients, nurses or caregivers and the patients' family can simply press the button to control the bed position according to the comfort of the patient's sleeping position so as to minimize the occurrence of decubitus

The wheelchair is essential for people with either spinal injury, limb injury, or trauma patients. The need at present is to customize the wheelchair based on the requirements of the disabled person. The maintenance and customization of a manual wheelchair is both simple and cost-effective when compared to powered wheelchairs, which are expensive and difficult to maintain in the long run. Accordingly, in this article, an attempt has been made to bring the facilities available in a powered wheelchair into the manual wheelchair, making it affordable to common people. Feasibility of a distinct manual wheelchair rear wheel rim is examined for various hub motor weights. The rear wheel of the manual wheelchair was replaced with an in-wheel direct drive hub-motor system. The proposed wheel model was designed using CATIA – V5 and an analysis was done using ANSYS software. A structural analysis was carried out to check the reliability and durability of the proposed wheel for different materials by changing hub-motor weights at various loading conditions. The nature of vibrations with respect to natural mode frequencies are found through modal analysis. Finally, the dynamic behavior of the proposed motorized wheel was examined using harmonic response analysis. Simulation results show the robustness of the proposed design and viability for real-time implementation.
