HActivityNet: A Deep Convolutional Neural Network for Human Activity Recognition

Human Activity Recognition (HAR), a vast area of a computer vision research, has gained standings in recent years due to its applications in various fields. As human activity has diversification in action, interaction, and it embraces a large amount of data and powerful computational resources, it is very difficult to recognize human activities from an image. In order to solve the computational cost and vanishing gradient problem, in this work, we have proposed a revised simple convolutional neural network (CNN) model named Human Activity Recognition Network (HActivityNet) that is automatically extract and learn features and recognize activities in a rapid, precise and consistent manner. To solve the problem of imbalanced positive and negative data, we have created two datasets, one is HARDataset1 dataset which is created by extracted image frames from KTH dataset, and another one is HARDataset2 dataset prepared from activity video frames performed by us. The comprehensive experiment shows that our model performs better with respect to the present state of the art models. The proposed model attains an accuracy of 99.5% on HARDatase1 and almost 100% on HARDataset2 dataset. The proposed model also performed well on real data

Musculoskeletal pain and physical health status among confirmed COVID-19 patients of Bangladesh

COVID-19 pandemic is now a great headache for the world population. Respiratory symptoms are the main presentation of COVID-19. However, musculoskeletal pain, headache, loss of taste and smell sense, and neurological manifestations may occur. Identification of patterns of musculoskeletal pain, fatigue and physical health status in COVID-19 is crucial. In this cross sectional study, a total 380 individuals with COVID-19 were recruited from the population following selection criteria. Pain varied widely in hip, neck, leg and calf muscles, back and spine, shoulder, arms and hand, and other parts of the body among the respondents. Inconstant, among respondents of younger age group (aged ≤50 year), 37.59% had moderate pain, 6.77% had severe pain, 13.91% had mild pain, and 41.17% had no pain. On the other hand, among older respondents (aged >50 year) 47.37% had moderate pain, 25.44% had severe pain, 13.15% had mild pain, and 14.03% had no pain. The differences between two groups was statistically significant (p<0.05). However, there was no difference in frequency of pain between males and females. Those respondents who had pain was reported having physical health worse than the average compared to that of those who had no pain. BSMMU J 2021; 14 (COVID -19 Supplement): 1-

Asymmetrical Achilles tendon ossification and rare rear heel pain

Achilles tendon ossification is not a frequent association of posterior heel pain in pain physicians’ daily practice. The condition has been reportedly common following rear heel trauma (repetitive heel stress injury), surgery (club foot surgery); however, some endocrino-metabolic, haematological disorders can also contribute to Achilles tendon ossification. Shape of ossified tendon mass varies from discrete (single/multiple) to extensive variety; and as per literature review, in bilateral cases they are alike. To be intriguing, here in this write-up, we demonstrate asymmetrical (in terms of clinical features and radio-imaging findings), bilateral Achilles tendon ossification in a 70-year-old retired farmer, first time in literature

Case Report Piriformis Syndrome in Fibromyalgia: Clinical Diagnosis and Successful Treatment

Piriformis syndrome is an underdiagnosed extraspinal association of sciatica. Patients usually complain of deep seated gluteal pain. In severe cases the clinical features of piriformis syndrome are primarily due to spasm of the piriformis muscle and irritation of the underlying sciatic nerve but this mysterious clinical scenario is also described in lumbar spinal canal stenosis, leg length discrepancy, piriformis myofascial pain syndrome, following vaginal delivery, and anomalous piriformis muscle or sciatic nerve. In this paper, we describe piriformis and fibromyalgia syndrome in a 30-year-old young lady, an often missed diagnosis. We also focus on management of the piriformis syndrome
