Principles of brain plasticity in improving sensorimotor function of the knee and leg in healthy subjects: A double-blind randomized exploratory trial

Background: Principles of brain plasticity is used in the treatment of patients with functional limitations to improve sensorimotor function. Training is included in the treatment of knee injury to improve both patient-reported function and sensorimotor function. However, impairment in sensorimotor function often persists despite training. Therefore, it was suggested that training programs need to be more effective to improve sensorimotor function after knee injury. The aim of the current study was to investigate if principles of brain plasticity that have been successfully used on the hand and foot to improve sensorimotor function can be applied on the knee. We hypothesized that temporary anesthesia of the skin area above and below the knee would improve sensorimotor function of the ipsilateral knee and leg. Methods: In this first double-blind exploratory study, 28 uninjured subjects (mean age 26 years, range 19-34, 50% women) were randomized to temporary local cutaneous application of anesthetic (EMLA (R)) (n=14) or placebo cream (n=14). Fifty grams of EMLA, or placebo, was applied on the leg 10 cm above and 10 cm below the center of patella, leaving the area around the knee without cream. Measures of sensory function (perception of touch, vibration sense, knee kinesthesia) and motor function (knee muscle strength, hop test) were assessed before and after 90 minutes of treatment with EMLA or placebo. The paired t-test was used for comparisons within groups and the independent t-test for comparisons between groups. The number of subjects needed was determined by an a priori sample size calculation. Results: No statistically significant or clinically relevant differences were seen over time (before vs. after) in the measures of sensory or motor functions in the EMLA group or in the placebo group. There were no differences between the groups due to treatment effect (EMLA vs. placebo). Conclusion: We found no effect of temporary cutaneous anesthesia on sensorimotor function of the ipsilateral knee and leg in uninjured subjects. The principles used in this study remain to be tested in subjects with knee injury

Impact of Integrated Watershed Management on Complex Interlinked Factors Influencing Health: Perceptions of Professional Stakeholders in a Hilly Tribal Area of India

Lack of access to water has a significant impact on the health of people in tribal areas, where water in households as well as for productive purposes is essential for life. In resource-limited settings such as hilly tribal areas, implementation of an integrated watershed management programme (IWMP) can have a significant impact on public health by providing a solution to water scarcity and related problems. The professional stakeholders in rural healthcare and development administration are important pillars of the system that implements various programmes and policies of government and non-government organizations, and act as facilitators for the improvement of public health in tribal areas. Information about the perceptions of these stakeholders on public health implications of the integrated watershed management programme is important in this context. A qualitative study was conducted using face to face semi-structured interviews and focus group discussions (FGDs) with stakeholders involved in healthcare provision, education and development administration. The transcripts of interviews and FGDs were analyzed using manifest and latent content analysis. The perceptions and experiences shared by healthcare and development administration stakeholders suggest that implementation of IWMP in tribal areas helps efficient water and agriculture management, which results in improved socio-economic conditions that lead to positive health outcomes

doctors' knowledge, attitudes and prescriptions

The aim of the study was to examine the relationship between guideline recommendations on asthma management, and the performance of doctors in five different European health care contexts. Knowledge, attitudes and prescribing behaviour of doctors recruited to an educational project was investigated. A total of 698 general practitioners from Germany, The Netherlands, Norway and Sweden, and 94 specialists from the Slovak Republic participated. A questionnaire was used to assess their knowledge and attitudes. Antiasthmatic drugs dispensed to their patients reflected their prescribing behaviour. In response to questions on how to treat chronic asthma, most doctors were in agreement with guideline recommendations. In practice, however, the proportion of asthma patients receiving inhaled steroids varied almost twofold, ranging 31% in Germany to 58% in The Netherlands. On questions related to exacerbation of asthma, German and Slovakian doctors often preferred treatment with antibiotics to steroids. They also more often associated yellow-green sputum with bacterial infection. In conclusion, although many doctors in different health care contexts have accepted the recommendations given in guidelines, the proportion of their patients treated accordingly differed. German and Slovakian doctors seem to attach less importance to the inflammatory features of asthma than the doctors from the other three European countries
