Review on design and control aspects of ankle rehabilitation robots

Abstract: Ankle rehabilitation robots can play an important role in improving outcomes of the rehabilitation treatment by assisting therapists and patients in number of ways. Consequently, few robot designs have been proposed by researchers which fall under either of the two categories, namely, wearable robots or platform-based robots. This paper presents a review of both kinds of ankle robots along with a brief analysis of their design, actuation and control approaches. While reviewing these designs it was observed that most of them are undesirably inspired by industrial robot designs. Taking note of the design concerns of current ankle robots, few improvements in the ankle robot designs have also been suggested. Conventional position control or force control approaches, being used in the existing ankle robots, have been reviewed. Apparently, opportunities of improvement also exist in the actuation as well as control of ankle robots. Subsequently, a discussion on most recent research in the development of novel actuators and advanced controllers based on appropriate physical and cognitive human-robot interaction has also been included in this review. Implications for Rehabilitation Ankle joint functions are restricted/impaired as a consequence of stroke or injury during sports or otherwise. Robots can help in reinstating functions faster and can also work as tool for recording rehabilitation data useful for further analysis. Evolution of ankle robots with respect to their design and control aspects has been discussed in the present paper and a novel design with futuristic control approach has been proposed.

On modal analysis of axially functionally graded material beam under hygrothermal effect

Abstract: This investigation focuses on the modal analysis of an axially functionally graded material beam under hygrothermal effect. The material constants of the beam are supposed to be graded smoothly alo...

Risk factors for musculoskeletal disorders in manual harvesting farmers of Rajasthan.

Abstract: Manual harvesting is a physically demanding occupation with several work-related issues in which musculoskeletal disorders (MSDs) happen most commonly The risk factors for MSDs among manual harvesting farmers are not investigated properly in low and low-middle-income nations Therefore, a study among 140 farmers of Rajasthan, India was carried out through the usage of Nordic Musculoskeletal Questionnaire and the Rapid Upper Limb Assessment (RULA) technique to identify ergonomic risks χ2 analysis was used to find the relationship between the MSDs and various factors Also, logistic regression methodology was applied to get the most influencing factor for MSDs in different body regions The lower-back, fingers, shoulders and wrists/hands were the body parts in which more than 50% workers reported MSDs MSDs in one or more body regions were found to be associated with age, daily working in farms, farming experience, gender, hand dominance and perceived work fatigue The age was majorly associated with MSDs in all body regions except the shoulder and neck as per the outcome of logistic regression The outcome of RULA grand score had been found higher than or equal to 5 in 92% of the farmers which give directions for further research and changes
