Effects of Stimulation Conditions and Waveforms on Muscle Contractile Characteristics

Song Tongjin,Khang Gon The Korean Society of Medical and Biological Engin 2005 의공학회지 Vol.26 No.2

This study was designed to apply the stimulation system developed in our laboratory to investigate how the stimulation conditions affect the muscle contractile characteristics in the isometric condition as well as during the FES standing/walking. Four paraplegic and ten healthy subjects participated in this study, and their knee extensors were voluntary contracted or electrically stimulated to measure the muscle force and the fatigue index for different waveforms of the pulse train. We also investigated different combinations of the electrode positions during standing/walking. It was confirmed that continuous and high-frequency stimulation causes faster fatigue than intermittent and low-frequency stimulation. Fatigue resistance was higher around the optimal muscle length than at a stretched position in healthy subjects, whereas the opposite was observed in paralyzed subjects. The paired t-test results with the level of significance at 0.01 indicated that the sinusoidal waveform generated the largest torque among the four typical waveforms. Although statistically not very significant, the sinusoidal waveform also generated, in general, the highest fatigue resistance at an intensity level below the supramaximal stimulation. One of the paraplegic subject who participated in the standing/walking program can now stand up for 1 minute and 50 seconds with the knee extensors, and walk for about 5 minutes at the speed of 12m/sec.

The purpose of this paper is to analyze the effect of color of cigarette cases on the consumers` purchasing attitude. First of all, in an attempt to assess the consumers` attitude on the colors, we explored the preferred colors by the consumers and developed an attitude scale measured with a questionnaire of 14 questions, we also built a research model to analyze the influence which the colors of cigarette cases exert on the consumers, attitude and conducted the analysis on the basis of the actual data. In addition, we made a Conjoint-analysis to measure the usefulness of the case colors. Followings are the results of the analysis ; First of all, the review of T-test proved that the case color causes changes in the consumers` purchase attitude. For example, it has been reveled that red is not preferred as a case color. Secondly, the result of analysis of variance showed that consumers` smoking habits moderate between the choice of case colors and consumer`s buying attitude. For instance, heavy smokers in comparison with nonsmokers or lightsmokers much preferred blue over red. Thirdly, the outcome of conjoint analysis revealed that regular smokers prioritize the taste of cigarettes when purchasing a pack of cigarettes and the color of the case is also considered as a leading contributor. An ideal combination of cigarette attributes turned out to be long, mild taste with a blue or white case. This research may contribute to the related tobacco industry when developing a new product even though it bears a couple of limitation such as consideration of only limited colors in the attitude research and exclusion of a variety of case design due to the complexity of analysis.
