Movement Rehabilitation in Physiotherapy after Stroke: The Role of Constraint-Induced Movement Therapy

Stroke is increasingly becoming a global health problem. This is because it may lead to death, Long-term disability such as in motor function, and significant burden to the patients and their families. The disability can be prevented or rehabilitated using a physiotherapy technique known as constraint-induced movement therapy (CIMT). The CIMT comprises of task practice with the affected limb, constraint of the unaffected limb, and transfer package to foster compliance and increase the amount of task repetition. It helps to reestablish normal motor control through facilitating changes in physiological functions of the brain, improvement in real-world arm use, and movement precision and quality. However, its protocols vary. Some protocols use number of hours and others use number of repetitions to determine the intensity or the amount of task practice. This chapter argued that CIMT is effective, but the protocols that use a number of hours of task practice are not clear and are resource intensive; and as such they could interfere with the process of clinical decision making. Consequently, it proposed the use of a number of repetitions of task practice to determine the intensity or the amount of task practice and extending the application of CIMT to those with severe impairments after stroke

Determining house price for mass appraisal using multiple regression analysis modeling in Kaduna North, Nigeria

The research applied Multiple Regression Analysis (MRA) in estimating house price for mass appraisal in Kaduna north, Nigeria. Two basic micro determinants of house price were considered, namely; structural attributes and location of property. Using a sample of 106 house sale transactions data which were recorded between 2011 to 2015, MRA was used to determine the structural variables and locational attributes that have statistically significant influence on the house price. It was found that among the variables included in the MRA, year of transaction, type of house, availability of swimming pool, availability of security post, type of door and location of the property were significant in determining house price in Kaduna. However, number of bedroom, number of living room, type of ceiling, condition of the house were not significant in influencing house price. Using the significant variables, a mass appraisal model was developed for the study area. The performance of the model was evaluated using the ratio study method and the model was found to be satisfactory. It was recommended that, this model be used in mass appraisal of residential properties in Kaduna north in the future, with a view to improve accuracy, objectivity, efficiency, and fairness of the property taxation system, which will lead to generating more revenue for the government and, encourage physical infrastructural development in Kaduna North.Keywords: Mass Appraisal, Multiple Regression Analysis (MRA), House Price, Valuatio

Views and experiences of discharged COVID-19 patients in Kano, Nigeria : a qualitative study

Introduction: COVID-19 has spread globally, thereby contributing to substantial hospitalisation rates and morbidity. However, little or no information is available on the experiences of patients with COVID-19 in an African-setting. The study aimed to explore the experiences of patients with COVID-19. Methods: semi-structured interviews were conducted via telephone with eleven individuals who were managed and discharged due to COVID-19. A descriptive phenomenological approach to qualitative research was employed and participants were mainly asked about their experiences before, during and after hospitalisation for COVID-19. Data were analysed using thematic analysis. Results: patients' viewpoints were suggestive of community and secondary transmission of COIVD-19 in the study area. A few participants experienced severe symptoms. Most participants tend to resign their condition to fate; while some displayed unfounded conspiracy theories. Nevertheless, precautionary measures to prevent infection were largely observed. COVID-19 also negatively affected activities of daily living of the participants. Furthermore, the participants were generally satisfied with quality of care provided. However, areas of patients' education, isolation centre set-up and caregiver-patient interaction needed further improvements. Lastly, experience of fear and stigma during post-hospitalisation were common. Conclusion: COVID-19 impacted negatively on the lives of the studied population. However, their experience during hospitalisation was generally positive

Dynamic relationship of exchange rates and crude oil prices in South Africa: are there asymmetries?

We estimated the relationship between the exchange rates and crude oil prices for the period of 1960 to 2013. Based on Engle-Granger we found that the variables are cointegrated means there exist long-run relationship. However, when we move on to TAR and MTAR models the findings are opposite as there is no element of cointegration and the speed of adjustment is symmetric. This shows that based on TAR and MTAR models the effects of exchange rates on crude oil prices is insignificant. The policy relevance is that South African authority need to monitor its exchange rates persistently related to other currencies more especially American dollar because it determined the crude oil prices that might have greater influences on other macroeconomic variables

Impact of communication delay on distributed load frequency control (dis-LFC) in multi-area power system (MAPS)

In this paper, impact of communication delay on distributed load frequency control (dis-LFC) of multi-area interconnected power system (MAIPS) is investigated. Load frequency control (LFC), as one of ancillary services, is aimed at maintaining system frequency and inter-area tie-line power close to the scheduled values, by load reference set-point manipulation and consideration of the system constraints. Centralized LFC (cen-LFC) requires inherent communication bandwidth limitations, stability and computational complexity, as such, it is not a good technique for the control of large-scale and geographically wide power systems. To decrease the system dimensionality and increase performance efficiency, distributed and decentralized control techniques are adopted. In distributed LFC (dis-LFC) of MAIPS, each control area (CA) is equipped with a local controller and are made to exchange their control actions by communication with controllers in the neighboring areas. The delay in this communication can affect the performance of the LFC scheme and in a worst case deteriorates power system stability. To investigate the impact of this delay, model predictive controller (MPC) is employed in the presence of constraints and external disturbances to serve as LFC tracking control. The scheme discretizes the system and solves an on-line optimization at each time sample. The system is subjected to communication delay between the CAs, and the response to the step load perturbation with and without the delay. Time-based simulations were used on a three-area MAIPS in MATLAB/SIMULINK environment to verify the investigations. The overshoot and settling time in the results reveals deterioration of the control performance with delay. Also, the dis-LFC led to zero steady states errors for frequency deviations and enhanced the MAIPS’ performance. With this achievement, MPC proved its constraints handling capability, online rolling optimization and ability to predict future behavior of systems

Factors influencing consumer’s retail formats choice for fresh fruits purchase in Klang Valley Malaysia

This study attempts to identify attributes or factors influencing consumers’ retail formats choice in fresh fruits (FF) purchase. The study covered consumers in Klang Valley area, Malaysia and period of the study is between June to December 2014. Seven hundred (700) respondents were randomly selected using multi- stage cluster sampling technique. The demographic characteristics result of the respondents includes their educational level, income level and their marital status. The product attributes considered most important by the fresh fruits consumers are level of ripening (72%), size and shape of the fruit (65%) and color of the fruits (63%). Freshness, safety of the product and product quality are the three factors yielded from the factor analysis. Likewise, convenience, entertainment and services offered are the retail formats attributes considered by the fresh fruits consumers. From the regression results it was observed that all the estimated factors have significant effect on frequency of visit to the traditional formats. However, only quality and entertainment were the significant factors affecting patronage of modern retail formats. The finding of this research will help the retail formats managers and policy makers identify the salient issues to be considered in fresh fruits marketing strategies

Adherence to Protective Measures against Hearing‑Related Hazards of Mobile Phone Users among University Students

Background: Mobile phone is an integral part of the society used by almost all. Youth in Nigerians are recognized as the most active users of mobile phones. There are about 1.1 billion youth people globally at risk of noise‑induced hearing loss from unsafe listening. The awareness and adherence to hearing conservation measures against the hearing‑related hazards of mobile phones have not been evaluated in our environment. Aims: To determine the knowledge and adherence to protective measures against the hearing‑related hazards of mobile phones among university students. Materials and Methods: The study was a cross‑sectional descriptive type, conducted among university students. Ethical clearance was obtained from the institutional review committee, a multistage random sampling technique was used to recruit the participants, and a specially designed and validated questionnaire was used to collect the data. The data were analyzed using Statistical Product and Service Solutions (SPSS) version 20.0. Results: The age of the respondents ranged from 16 to 40 years with a mean age of 23.6 ± 5.3 years. Very few of the participants (19.1%) adhere to protective measures to mitigate hearing‑related hazards of mobile phones, although about half (52.1%) had good knowledge of hearing  conservation measures. There was a statistically significant association between knowledge of hearing‑related hazard of mobile phone (P = 0.038) and knowledge of protective measures (P = 0.000) with the adherence to protective measures, respectively. Conclusions: The knowledge and  adherence to protective measures against the hearing‑related hazards of mobile phones were poor among the respondents. Keywords: Hearing loss, mobile phone, protective measures, university student

Analysis of Cowpea (Vigna unguiculata) Marketing and Price Trends in Selected Markets of Argungu Local Government Area, Kebbi State, Nigeria

The study analyzed cowpea marketing and price trends in selected rural and urban markets of Argungu Local Government Area, Kebbi State, Nigeria. A single-stage sampling technique was used for sample selection. The samples were collected from purposively selected Kara markets in Argungu (reference market), Felande, Gulma, Lailaba and Sauwa (supplying markets) from the selected Districts. Primary data were obtained from a sample of 100 marketers with the aid of the structured questionnaire. Descriptive statistics and spatial price model were employed in analyzing the data. Results of the analysis shows an average age of marketers to be 34 years, 69% were married and 62% have formal education with an average household size of 8 persons. However, 73% were discovered not join any cooperative association while 79% of them do not have access to credit to finance their business. Analysis of spatial aspects of pricing efficiency showed that the positive price spread is slightly high, even after considering plausible levels of unmeasured transaction costs. The trend in price revealed higher price per bag during the off-season (N27, 000/bag) in July and August and low (N15, 000) during harvest (October,November, December and January). Temporal aspects showed considerable risk was involved in storage operations to achieve high profits. The marketing channels identified in the study area were; Farmers, Village merchants, Wholesalers, Retailers, Processors and finally the Consumers. The constraints identified in the study area were lack of access to credit (25.69%), inadequate market information (24.59%), inadequate market infrastructure (22.65%), provision of quality product (16.02%) and poor storage facilities (11.05%). It is recommended that sellers should form cooperatives that can support them in provision of physical facilities and better dissemination of market intelligence and facts. Accordingly, to alleviate the problem of access to credit in the study area, awareness campaign and provision of such credit facilities at affordable level by the relevant stakeholders (State and Local Government authorities) could be an excellent  performance in enhancing the marketing activities in the study area
