REAL-TIME MEASUREMENT USING EMG AND MOTION CAPTURE SYSTEMS

Real-time feedback to participants of a particular parameter has been a viable tool for learning, training and rehabilitation for many years. The type of feedback that was usually given was in the form of kinematics (e.g. accelerometry) or kinetics (e.g. force). The manner in which the feedback has been given has been altered greatly in recent years by the development of equipment and software that enables the researcher to accomplish the feedback tasks much more easily than previously. In this paper, real-time electromyography (EMG) and real-time kinematics will be presented. The most recent equipment for both real-time EMG and kinematics will be presented along with examples from recent research papers that used such techniques

From Discrimination: A Journey to Justice and Understanding

There have been milestones toward understanding in the Civil Rights journey . Do these milestones reflect an advance in understanding and respect, or have fears, ignorances, and outright bigotry forged a wall against acceptance of the Afro-American into mainstream America? An area in the Northeast County of St. Louis, Missouri was selected for this study as it encompassed 1036 residential homes . The area integrated starting about 1978. From surveys conducted by the Chairman of the Board of Trustees of this subdivision, in 1991 and 1992, it was determined that 63\u27l. of the families now are Afro-American, 37% are Caucasian or other. A questionnaire listing twenty questions pertaining to understanding, acceptance, feelings toward others of opposite race, was submitted to some residents and former residents. The variable to be measured was labeled Afro-American Caucasian Understanding (ACU). It was determined beforehand that the sample group of thirty-two be equally apportioned to Afro-American and to Caucasian. The survey was conducted with the assistance of the Chairman of the Board of Trustees who was an Afro-American male, and a Caucasian female member of the church within the area working with a Ladies Guild . This paper touches many facets of everyday existence including groups of school age individuals, entertainers, ball players, business persons, political persons, church people . Results of the survey indicated that there has been an increased understanding among the two cultures as measured against what might be expected from a Likert mean. Given a normal distribution, using the Likert scale with scorings at random one to five, on a twenty question survey, one would expect a mean score of 60 . The minimum score would be twenty, maximum score would be one hundred . The tables submitted gave information supporting a positive measurement toward understanding

Implementation of Bright Futures Health Screening Tools At a School-Based Health Center

A practice improvement project was conducted to implement the use of Bright Futures health screening tools at a rural school-based health center. Some healthcare issues may be difficult for an adolescent to disclose or the adolescent may not understand that the concern should be addressed. A good screening tool should assist a nurse practitioner to help students to disclose difficult information and to provide preventative health care services. It was determined that the Bright Futures Adolescent Supplemental Questionnaires were an effective and efficient tool in increasing relevant knowledge for the pediatric nurse practitioner in this setting. Students were willing and able to complete the forms and take part in screening for potential health concerns. Use of these screening tools led to the discovery of risk factors and problems that might not otherwise have come to light

ARCH-TYPE AND SHOE INTERACTIONS DURING RUNNING

The purpose of this study was to examine the interaction of foot arch-type and running shoe midsole hardness on lower extremity mechanics. Ground reaction forces {GRF) and kinematic timing variables were examined during the support phase of overground running. Eighteen healthy, male, recreational runners served as subjects. They completed 15 running trials in two different shoes; 1) a soft midsole shoe and 2) a hard midsole shoe. Foot type was quantified using a Tekscan pressure mat. From the pressure data, a ratio of forces on the midfoot to the forces an the entire foot was generated to categorize runners as high arched, normal arched and flat arched. Three dimensional kinematic data were collected using three 200 Hz high speed video cameras. Ground reaction force data were collected at 1 000 Hz using an AMTI force platform. Significant differences were found between shoe conditions for 5 GRF parameters (p < 0.05). No significant differences were found between arch types for any of the GRF parameters ( p < 0.05). In addition, no significant differences were found between shoe conditions or between arch types for any of the kinematic timing parameters @ < 0.05). However a significant interaction was observed between shoe conditions and arch groups for total support time and for the percent time to maximum femoral rotation. Results of the study indicated that force ratio footprints was an ineffective method of predicting either kinematic or kinetic changes in running mechanics

Mortality from head injury over four decades in Scotland

Although the causes of head injury, the population at risk and approaches to prevention and treatment are continually evolving, there is little information about how these are reflected in patterns of mortality over time. We used population based comprehensive data uniquely available in Scotland to investigate changes in the total numbers of deaths from 1974 to 2012, as well as the rates of head injury death, from different causes, overall and in relation to age and gender. Total mortality fell from an annual average of 503 to 339 with a corresponding annual decrease in rate from 9.6 to 6.4 per 100,000 population, the decline substantially occurring between 1974 and 1990. Deaths in children fell strikingly but rose in older people. Deaths in males fell to a greater extent than females but remained at a higher rate overall. Initially, a transport accident accounted for most deaths but these fell by 80%, from 325 per year to 65 per year over the 39 year period. Deaths from falling and all other causes did not decline, coming to outnumber transport accident deaths by 1998, which accounts for the overall absence of change in total mortality in recent years. In order to reduce mortality in the future, more effective measures to prevent falls are needed and these strategies will vary in younger adults (where alcohol is often a factor), and in older adults where infirmity can be a cause. In addition, measures to sustain reductions in transport accidents need to be maintained and further developed
