Ankle sprain Injury is one of the most common ankle injuries due to domestic or sporting accidents. There is a need for greater demand for quick and effective ankle rehabilitation system (ARS). Nowadays, research on ARS has gained a great attention than manual clinical method in medical areas such as orthopedic injuries, pediatrics sport medicine and industrial services. It can improve the treatment conditions by reducing the dependency of doctors’ supervision, help patient with less movable to have home-based rehab exercise and help to speeds up recovery. There are currently available ARS that can provide effective ankle rehabilitation treatment such as Visual, Non-Visual and Robot-aided. In this paper, the critical review of ARS is conducted to evaluate the effectiveness of ARS in terms of provided setting criteria. The strengths, weaknesses, opportunities and threats of each ARS is discussed and compared to identify the most suitable home application of ARS for ankle sprain patient. From the comparison, the most suitable home application ARS is the visual marker-less based ARS system which give user-friendly, efficiency, validity in performance and cheaper cost.

Design of electroadhesion pad for improving grasping friction of soft robotic glove

2024-02-08 , Muhammad Hisyam Rosle , Amirul Syafiq Siraj Jaafar , Muhammad Nazrin Shah Shahrol Aman , Abdul Nasir Abd. Ghafar

A soft wearable robotic glove was developed to provide grasping assistance to patients with neuromuscular impairment. Sufficient friction forces is required in grasping objects as lack of friction between the glove and the surface of the object will result in slippage. In this paper, the application of electroadhesion in order to increase the frictional force for wearable robotic gloves is presented. The characteristics of the proposed electroadhesion pad is lightweight, thin, and easy to be operated by the patients. The work involves designing and fabricating soft electroadhesive pad and embedding them to the robotic glove. The electroadhesion pad was supplied with voltage lower than 400V for safety purposes. Experimental results verified that the proposed design of electroadhesion pad can increase the friction force when grasping various objects. Experimental results shows that the higher the contact area of electroadhesion applied, the higher the resulted frictional forces. Moreover, it can be noted that higher contact area of electroadhesion requires a higher voltage input to produce electroadhesive force.

Fabrication of Parallel Ankle Rehabilitation Robot

2021-01-01 , Ismail M.K.A.B. , Muhammad Nazrin Shah Shahrol Aman , Wan Azani Wan Mustafa

In this modernization era, we have been showered with multiple of technologies which have leaded a much more comforting lifestyle especially to humankind. This report presents a survey of development of parallel based ankle rehabilitation robot. As a result, robot therapy systems have been developed worldwide for training lower extremities. This work reviews all current robotic systems to date for ankle injury, with the aim of showing a clear starting point in the field. It also discusses numerous challenges faced by engineers in designing this robot, including framework stability, universal evaluation criteria to assess end-user comfort, safety and training performance and the scientific basis on the optimal rehabilitation strategies to improve ankle condition. Nowadays, there is so many treatment machine and it can be use at hospital or physiotherapy unit, clinic, and health centre with expensive cost This development is to reduce a cost for the treatment and also make the model easy to carry anywhere Based on the previously defined constraints, the goal of robotic robot development for ankle recovery is to create a treatment for ankle recovery by integrating software and hardware process, also analyses performance of ankle rehabilitation robot model. This project will consist of two main parts, which are the design and development parts. For the software design, Solidworks are selected to make the dimension and design. For the development part, the material for the framework is an aluminum will be select and use. The result will be including a degree of freedom for the rotation of the platform using load and no load. This project mainly aids the users who is affected by stroke, illness or injuries due to accident and encouraging them to exercise regularly in house without consulting the physiotherapist in the hospital.

Parametric design optimization of an ankle rehabilitation robot using SolidWorks

2020-12-18 , Muhammad Nazrin Shah Shahrol Aman , Shafriza Nisha Basah , Khairul Salleh Basaruddin , Wan Khairunizam Wan Ahmad , Bin Ahmad S.A. , Wan Azani Wan Mustafa

This paper presents the approach to determine most suitable dimensions and volume of the proposed ankle rehabilitation robot design. This design aim is the robot needs to be portable without compromising the workspace of the proposed robot and it must fulfill all required basic ankle motions. To do this, optimisation was used to generate possible initial dimensions in order to achieve suitable length for the outer frame through minimization of the dimensions. Based on the selected variables and constraints, the result of the optimization shows minimization of the proposed design has been achieved through reduction of the dimension of the outer frame of the robot in which translate the reduction of the weight of the robot.

2020-12-18 , Mohd Al-Hafiz Mohd Nawi , Wan Azani Wan Mustafa , Muhammad Nazrin Shah Shahrol Aman , Syahrul Affandi Saidi , Ilham Shafini Ahmad Mahyudin , Mohd Aminudin Jamlos

The following literature review provides an overview of research and a summary of the most condition that relevant to the present study. The overview focuses on such parameter such as the effect of ambient condition (density and temperature), the effect of fuel injection, the effect of injection pressure, the effect of mass fuel and effect of nozzle diameter that probably effects into the droplets distribution, sprays evaporation and mixture formation of diesel spray. The preferred format has been choosing to allow an easier scanning and classification which intend to summarize the relevant topic and study regarding the diesel spray fields.

Correlation between Postural Stability and Lower Extremity Joint Reaction Forces in Young Adults during Incline and Decline Walking

Postural stability may be affected during slope walking, as there are different body kinetics and kinematic responses compared with level walking. Understanding body adaptations toward different inclinations is essential to prevent the risk of injury from falls or slips. This study was conducted to determine the correlations between stability parameters and loading response in terms of joint reaction force at the lower-extremity joints during inclined and declined walking. Twenty male subjects walked in the level, incline, and decline directions on a custom-built platform at three different slope angles (i.e., 5°, 7.5°, and 10°). To determine the ground reaction force (GRF), joint reaction force (JRF), center of pressure (COP), and center of mass (COM), a motion capture system was used to read the data of the ten reflective markers and transfer them to visual three-dimensional (3D) software. Pearson’s correlation test was performed with statistical significance set at p < 0.05 to evaluate the correlation of the required coefficient of friction (RCOF), postural stability index (PSI), and COP-COM distance with the JRF. This study has identified that the JRF changes in opposition to the changes in the RCOF during the initial strike during incline and decline walking, as JRF increases, the RCOF decreases with different strengths of correlation. There is also a strong positive correlation between the PSI and JRF in the proximal–distal direction, where the JRFs change in accordance with the change in the PSI, and the JRF increases with the increment of PSI. In addition, the JRF of the lower extremity also changed in a manner similar to the COP-COM distance in the medial–lateral direction. Overall, each stability parameter was correlated with the JRF of the lower-extremity joints in different directions and strengths. This study demonstrated that slope walking is particularly affected by surface inclination in terms of stability and loading. Therefore, this research can serve as a basis for future studies on slopes, as there is no specific basis for a maximum degree of inclination that is safe and suitable for all applications.
