Thirty-four articles about the biomechanical characters of ankle joint dated between January 1989 and October 2007 weresearched in Medline and Elsevier SDOS databases to analyze and review the influential factors for dynamic characters of the anklejoint. The kinetics characters of the ankle joint include: The absolute value of the kinetics character of female is smaller than that ofthe male. However, there are few differences or even no differences between them for the relative value of the kinetics character. Thekinetics characters of the ankle joint become weak as the aging of adults. Foot length and instep height have great impact on thekinetics character of the ankle joint. The kinetics characters of the anklebone will change with its angular velocity. Thesuper-isometric concentric-eccentric contraction shows the best effect in strength training on the ankle joint. There are many factorsthat influence the dynamic characters of the ankle joint, and partial conclusions are still uncertain.

BACKGROUND:At present, the study to balance ability of functional ankle instability patients is less. The
balance ability deficiency may also be one of the important reasons for ankle repeated injury, so the research can effectively reduce the damage probability.
OBJECTIVE:To explore the static balance ability characteristics of functional ankle instability patients.
METHODS:Ten male subjects with unilateral functional ankle instability were enrol ed as the experimental group in the study, and other 10 healthy match-paired subjects were served as the control group. Their static balance ability was measured under double feet standing and single foot standing using win-pod system, the double feet testing lasted for 30 seconds and the single foot testing lasted for 10 seconds. Evaluation parameters of balance ability were obtained.
RESULTS AND CONCLUSION:During double feet testing, there were no significant differences in balance
ability parameters between the experimental group and the control group whether eyes be opened or closed (P>0.05), but the index values of double feet testing were obviously less than those of single foot testing. So we
concluded that in the double feet standing, there was no significant difference in the static balance ability between functional ankle instability patients and normal persons. Moreover, the static balance ability of double feet was
better than that of single feet. In the single foot standing of the affected foot, the static balance ability of functional ankle instability patients was slightly worse than that of the normal persons, especial y with eyes closed.
Comparison of the average swing between the X-axis and Y-axis found that in the process of maintaining balance posture, the swing direction of the body center of gravity was mainly in the anteroposterior direction.

BACKGROUND:One-legged standing with eyes closed is a method to test the muscle strength and the ability of body balance, it is considered to be an important quality indicator for evaluation of adults and elderly balancing
capability in our country. A lot of works have been done in many provinces and cities, but there is a lack of in-depth studies.
OBJECTIVE:To review the research progress of one-legged standing with eyes closed, to analyze its problem used in the physical fitness test and to prospect the future direction of the related researches.
METHODS:A computer-based search on CNKI database and Elsevier database was undertaken to identify the article of balance capacity. The key words were“eyes closed and single legged standing, balance ability,
physical fitness test”. Total y articles were searched and checked primarily, and those meeting the criteria were looked up.
RESULTS AND CONCLUSION:The standard of one-legged standing with eyes closed for the male is higher
than that for the female. Some elderly just stand for a short time in the test, and thus it is difficult to distinguish the balance ability. Elderly balance is significantly lower than that in young people. The same test method for adults and elderly people is employed, but whether it is scientific or not should be further studied. Various indicators in the test of one-legged standing with eyes closed have low correlation. For the above reasons, further studies
should be made before the test of one-legged standing with eyes closed becomes a valuable measurement of the balance ability in the national physique.

BACKGROUND: There was no uniform criterion for muscle force sense test of the sagittal plane of the ankle joint.OBJECTIVE: To explore the test-retest reliability of the ankle muscle force sense (MFS) under different target force.METHODS: The target force of the muscle was 25%, 50% and 75% maximal voluntary isometric contraction to measure MFS.Consistency degree of the repeated measures was evaluated by intra-class correlation (ICC) and standard error of measurement(SEM).RESULTS AND CONCLUSION: Interclass correlation coefficients of variable errors and absolute errors in MFS were more than0.75, and SEM of them were lower. ICCs of constant error of them were less than 0.75, and SEMs of them were greater. Thetest-retest reliability for variable errors and absolute errors of MFS was better when the target force was smaller.

Vitamin B1 self-assembled monolayer modified electrode (VB1-Au/SAMs/CME) was prepared and its electrochemical behavior was studied by cyclic voltammetry. The results showed that a self-assembled monolayer (SAM) was formed on the surface of gold electrode. \3-/4-redox couple was used as the electrochemical probe to study the electrochemical characteristics of SAM modified gold electrode and the results indicated that the existence of Vitamin B1 membrane on gold surface hindered the electron transfer. The electrochemical behaviors of dopamine(DA) and uric acid (UA) were investigated at VB1-Au/SAMs/CME. The results showed that the electrochemical oxidation of DA and UA could be electrocatalyzed. There were linear relationships between the anodic peak current and the concentration of DA(8.0×10-6-4.0×10-4 mol/L) and UA (6.0×10-5-2.2×10-4mol/L) respectively in differential pulse voltammograms. This modified electrode was effective to detect DA and UA in simultaneous determination of these species in a mixture.
