Load Evaluation

During this case study, the risks of posture, strength and repetition associated with the activity of manual coffee harvesting were evaluated. The sample studied was 26 volunteers who participated in the completion of a Nordic questionnaire, 10 of these were evaluated using observational,and postural tools and 8 people participated in the biomechanical evaluation of postural and muscular load using electromyography and inertial. Seven muscles and two body segments of the upper limbs were evaluated. The goal was to assessthe working conditions of coffee manual harvesting considering ergonomics.The results of the discomfortsweremanifested in the Nordic questionnaire where it was evident that throughout a workday harvesting coffee, the discomfort focuses on the back, lower back, hands,and feet. In the muscle load evaluation was identified that the muscles with the highest activity were the Extensor, Flexor Carpi Ulnar and the trapezius.On average,their muscular activity was20% of their maximum volunteer contraction when performing the statistical analysis. -Tics showed a greater correlation in muscle activationbetween the Carpi Radial Extender and the trapezius. In the postural evaluation of the body segments from the coffee harvesters evaluated, it was identified that they only maintain between 10% and 20% in neutral ranges, so they are always in risky conditions. In conclusion, it is necessary to carry out interventions in the Colombian coffee sector not only because of these evaluated conditions but also for theconditions in theirwork environment.

Objective: The goal of this case study was to analyze and evaluate the posture, force and repetitive movement risks associated with manual coffee harvesting activities. Materials and Methods: A self-discomfort report was administered to 28 participants, of whom 4 volunteered for an evaluation of postural load on muscular activity using electromyography and electrogoniometry. Eight upper limb muscles and the kinematics of the wrist and upper arm of the dominant arm were assessed. Results: The results of the self-discomfort report showed a greater demand, from the harvester’s perception, in areas such as the back, lower back, knees and feet during a period of one week of work. The outcomes of the muscular activity assessment showed that the extensor carpi ulnaris (ECR) was the muscle with the highest demand during the assessment. The dynamic activity of the muscle exceeded 20% of the maximum voluntary contraction (MVC), which classifies coffee harvesting as a threatening activity. The postural load on the body segments revealed that wrist deviation was critical due to an abnormal range of the wrists during the activity. Conclusions: It is necessary to improve the working conditions of the coffee harvesters.

Muscular Effort

This work addresses the problem of planning a robot configuration and grasp to position a shared object during forceful human-robot collaboration, such as a puncturing or a cutting task. Particularly, our goal is to find a robot configuration that positions the jointly manipulated object such that the muscular effort of the human, operating on the same object, is minimized while also ensuring the stability of the interaction for the robot. This raises three challenges. First, we predict the human muscular effort given a human-robot combined kinematic configuration and the interaction forces of a task. To do this, we perform task-space to muscle-space mapping for two different musculoskeletal models of the human arm. Second, we predict the human body kinematic configuration given a robot configuration and the resulting object pose in the workspace. To do this, we assume that the human prefers the body configuration that minimizes the muscular effort. And third, we ensure that, under the forces applied by the human, the robot grasp on the object is stable and the robot joint torques are within limits. Addressing these three challenges, we build a planner that, given a forceful task description, can output the robot grasp on an object and the robot configuration to position the shared object in space. We quantitatively analyze the performance of the planner and the validity of our assumptions. We conduct experiments with human subjects to measure their kinematic configurations, muscular activity, and force output during collaborative puncturing and cutting tasks. The results illustrate the effectiveness of our planner in reducing the human muscular load. For instance, for the puncturing task, our planner is able to reduce muscular load by 69.5\% compared to a user-based selection of object poses.

AbstractWarts are caused by human papilloma viruses (HPV) that can affect any part of the body including hands and feet. Verruca palmaris (VP) is a common manifestation due to HPV infection in keratinocytes of the palms. In the conventional system of medicine, VP is commonly managed through cauterisation, cryosurgery, surgical removal or topical ointments, which have many limitations. Scientific documentation for the treatment of VP by homoeopathic medicines is very scanty. In this context, the present case report is of a 40-year-old male patient, who had multiple warts on his right palm for more than 2 years. The patient was treated previously with allopathic medications and external applications, without any significant improvement. Homoeopathic remedy (i.e. Natrum mur) was initially administered in 30C potency for 30 days, but no improvement was observed in the patient. Interestingly, when the potency was increased to 200C, a speedy recovery was observed and the patient was fully cured within 3 months. Therefore, it can be concluded from the case study that VP, when treated on the basis of the totality of symptoms, with an accurately selected remedy in suitable potency results in cure. In this particular case, Natrum mur worked well for warts on the palm. Most importantly, it was observed in this case that the selection of right potency is very essential and it should match correctly with the susceptibility of the patient to result in rapid cure.

Rock climbers believe chalk dries the hands of sweat and improves the static coefficient of friction between the hands and the surface of the rock. The purpose of this study was to assess whether chalk affects geometric entropy or muscular activity during rock climbing. Nineteen experienced recreational rock climbers (13 males, 6 females; 173.5 ± 7.0 cm; 67.5 ± 3.4 kg) completed 2 climbing trails with and without chalk. The body position of the climber and muscular activity of the finger flexors was recorded throughout the trial. Following the movement sequence participants hung from a standard climbing hold until they slipped from the climbing structure, while the coefficient of friction and the ratio of the vertical forces on the hands and feet were determined. Although there were no differences in the coefficient of friction (P = .748), geometric entropy (P = .359), the ratio of the vertical forces between the hands and feet (P = .570), or muscular activity (P = .968), participants were able to hang longer after the use of chalk 62.9 ± 36.7 s and 49.3 ± 25.2 s (P = .046). This is advantageous because it may allow for prolonged rests, and more time to plan the next series of climbing moves.

Autosomal Recessive Pattern

Spinal Muscular Atrophy (SMA) is the second leading genetic disorder inherited in autosomal recessive pattern due to absence of SMN1 gene characterized by loss of motor neurons and progressive muscle wasting, often leading to dependent life and decreased life span. In Ayurveda, SMA can be considered as a type of janma jaata Vata vikara as it has been mentioned that: “Tatra va gati gandhanayoriti vata” that means all the movements of the body are controlled by vata. In Vata vyadhi Lakshanas, few symptoms like Anganam sosha (Atrophy or emaciation of limbs), Sankocha (Contraction), Kanja, Pangulya, Kubjatva (Lameness of hands and feet, hunch-back and shortness), are considered, few of which are also observed in the Spinal Muscular Atrophy. A 2yrs female patient was admitted in our I.P.D who was a known case of SMA II presented with complaints of inability in sitting for longer time without support, unable to stand and walk even with support. Through Ayurvedic principles we have treated adopting various vata hara treatment modalities & also with few palliative treatments as per the need in view of enhancing the quality living.

Background: From the evidence of failed injection-based growth factor therapies, it has been proposed that a naturally triggered uninterrupted blood circulation of the growth factors would be superior. Objective: We seek to stimulate discussions and more research about the possibility of using the already available growth factors found in the prostate gland and endometrium by starting a novel educable physiology, known as biological transformations controlled by the mind. Methods: We summarized the stretch-gated ion channel mechanism of the cell membrane, and offer several practical methods that can be applied by anyone, in order to stimulate and enhance the blood circulation of the growth factors from the seminal fluid to sites throughout the body. This details the practical application of our earlier published studies about biological transformations. Results: A previously reported single-patient case study has been extended, adding more from his personal experiences continually improving this novel physiological training and extending the ideas from our earlier findings in detail. Conclusion: The biological transformation findings demonstrate the need additional research to establish the benefits of these natural therapies to repair and rejuvenate tissues affected by various chronic diseases or aging processes.

Lower Back

Gridhrasi (Sciatica) is a disorder in which low back pain is found, that spreads through the hip, to the back of the thigh and down the inside of the leg. Mechanical low back pain (LBP) remains the second most common symptom related reason for seeing a physician. 85% of total population will experience an episode of mechanical LBP at some point during their lifetime. Fortunately, the LBP resolves for the vast majority within 2-4 weeks. There are many causes for low back pain, however true sciatica is a symptom of inflammation or compression of the sciatica nerve. The sciatica nerve carries impulses between nerve roots in the lower back and the muscles and nerve of the buttocks, thighs and lower legs. Compression of a nerve root often occurs as a result of damage to one of the discs between the vertebrae. In some cases, sciatic pain radiate from other nerves in the body. This is called referred pain. Pain associated with sciatica often is severe, sharp and shooting. It may be accompanied by other symptom, such as numbness, tingling, weakness and sensitivity to touch. There is only conservative treatment giving short term relief in pain or surgical intervention with side effect. But these are not successful and therefore those who are suffering from this are always in search of result oriented remedy. Walking distance and SLR test were taken for assessment parameter, VAS score was adopted for pain. Before treatment patient was not able to walk even 4 to 5 steps due to severe pain, was brought on stretcher and his SLR was 30° of right side. After 22 days of treatment he was able to walk up to 500 meters without any difficulty, SLR was changed to 60° and patient had got 80 % relief in pain. This case report showed that Ayurvedic protocol is potent and safe in the treatment of Gridhrasi.

Offender Reintegration

Successful social reintegration is critical if we are to reduce recidivism and crime in general. This voice of people article presents a background case for why effective offender reintegration services are key in South Africa, and the Eastern Cape in particular, through an example of the Offender Reintegration programme rendered by the National Institute of Crime Prevention and Reintegration of Offenders (NICRO). Apart from the paucity of literature on offender reintegration, very few voices from people working directly with these former offenders are ever heard. Therefore, this article seeks to address this gap by contributing to the body of knowledge on offender social reintegration.

Metabolism is the term employed to embrace the various physical and chemical processes occurring within the tissues upon which the growth and heat production of the body depend and from which the energy for muscular activity, for the maintenance of vital activity and for the maintenance of vital functions is derived (Best & Taylor 1950). The destructive processes by which complex substances are converted by living cells into more simple compounds are called catabolism. Anabolism denotes the constructive processes by which simple substances are converted by living cells into more complex compounds, especially into living matter. Catabolism and anabolism are part of all metabolic processes, the carbohydrate, fat and protein metabolism. The term anabolic refers only to substances that exert an anabolic effect on protein metabolism and are unlikely to cause adverse androgenic effects. They shift the equilibrium between protein synthesis and degradation in the body as a whole in the direction of synthesis, either by promoting protein synthesis or reducing its breakdown. The protein anabolic effect of anabolic steroids is not restricted to single organs but is the result of stimulated biosynthesis of cellular protein in the whole organism.
