ABSTRACT
Objective:To explore vibration, position and motion proprioception of the ankle joints after a stroke.Methods:Twenty-eight stroke survivors with impaired ankle proprioception were divided into a right-side stroke group ( n=18) and a left-side stroke group ( n=8). Twenty-two healthy volunteers constituted a control group. Vibration perception thresholds, passive and active joint angle resetting, and motion minimum thresholds were quantified among the stroke survivors on both the healthy and the affected side. With the controls the dominant and non-dominant sides were used. The differences in proprioception between the healthy volunteers and the stroke patients, between the affected side and the healthy side of the stroke patients, and between left- and right-side stroke patients were analyzed and compared. Results:Among the stroke survivors the vibration perception threshold on the affected side averaged (28.91±22.53)μm. The absolute difference in the perception of passive positioning was (5.49±5.39)° for 15° of plantar flexion and (4.48±3.89)° for 5° of dorsal extension. In active positioning plantar flexion was (5.23±4.34)° and for 30° of plantar flexion it was (3.26±1.73)°. The 5° dorsal extension error was (4.97±3.48)°. The motion perception thresholds between 20° of plantar flexion, 10° of plantar flexion and the neutral position were significantly higher, on average, than among the control group. The stroke group also had significantly higher motion perception thresholds than the control group.Conclusion:The vibration, position, and motion sense of the ankle joint on a stroke survivor′s affected side tend to be impaired, with the impairment of vibration and motion sensing tend to be more substantial. After stroke, there is also mild impairment of vibration, position and motion sensing in the healthy ankle joint. The impairment of proprioception caused by right cerebral hemisphere injury may be more serious than that caused by injury on the left.
ABSTRACT
ObjectiveTo explore the features and assessment for far space neglect in left spatial neglect patients after right brain stroke. MethodsFrom January to October, 2021, 30 left unilateral spatial neglect (USN) patients after right stroke (patients, n = 30) from Beijing Bo'ai Hospital and healthy volunteers matching with gender, age and level of education (controls, n = 30) were evaluated with line cancelation (LC), star cancelation (SC) and line bisection (LB) tests, nearly and far away. The 25 controls were evaluated with LB on the second day. ResultsNo line or star was omissed in the controls. Both the deviation and percentage were more in the patients than in the controls (|t| > 4.319, P < 0.001). Both the deviation and percentage were less different for all the test (|Z| < 1.638, t = -1.282, P > 0.05) between nearly and far away, except the deviation of LB (t = -4.994, P < 0.001). The ICC of test-retest was above 0.462 (P < 0.01). ConclusionRight brain stroke patients with USN may present far spatial neglect, which can be assessed with LB.
ABSTRACT
Objective To investigate the effects of aquatic Taiji Quan on balance function of patients with incomplete spinal cord injury. Methods From March to December, 2015, 30 patients with incomplete spinal cord injury received aquatic Taiji Quan exercise based on rou-tine rehabilitation, 30 minutes every day, five times a week for five weeks. They were assessed with Berg Balance Scale (BBS) before and after exercise. Dynamic balance function and static balance function were also assessed with Active Balancer assessment. Results The BBS score significantly improved after exercise (t=-9.652, P3.528, Z>-2.590, P0.05). The dynamic stability limit range enlarged (t=-4.516, P<0.01), and the time to target significantly shortened (t=4.530, P<0.001). Conclusion Aquatic Taiji Quan can improve the balance function of patients with incomplete spinal cord injury.

ABSTRACT
Objective To measure the temperature sensation threshold of trunk skin in healthy adults. Methods The threshold of cold sensation, warm sensation, cold pain sensation and heat pain sensation of trunk skin key points (T3, T7 and T11) were measured with Thermal Sensory Analyzer in 123 healthy adults. Results The thresholds of cold, warm, cold pain and heat pain sensations were obtained. The stan-dard deviation of cold and warm threshold was less than that of heat pain. The range of cold sensation threshold was the largest. The heat pain sensation threshold increased with segmental declining and the sensation threshold increased with age. Conclusion Normal reference value should be established variously with the segment and age. The threshold of cold, warm varies less, while the threshold of cold pain and heat pain varies too much.

ABSTRACT
Objective To study the general rule in the power spectrum percentage of balance when normal people standing and the dif-ferences of the power spectrum percentage between normal people and the stroke patients. Methods 30 normal people and 30 stroke patients was tested with Active Balancer EAB-100 (Sakai Iryo) open-and close-eye. The whole path length, circumference area and the percentages of power spectrum on the X, Y and Z axes were recorded. The correlation and the differences were analyzed. Results The percentages of power spectrum were not statistically correlated (P>0.05) with age, height, weight or gender. There was significant difference between two groups in the percentage of power spectrum (P<0.05). On the frequency spectrum, the ratio rised on the low and middle frequency part, espe-cially within 0.2~2 Hz, but the ratio decreased on the high frequency part (2~10 Hz) (P<0.05). Conclusion The percentage of power spec-trum can be an important reference in assessing the stroke patients' balancing functions.
ABSTRACT
@#Objective To analyze the characteristics of balance impairment in stroke patients over 60 years old. Methods This was a retrospectivecase-control study. Subjects were divided into two groups, normal control group and stroke group. Tetrax Interactive Balance Systemwas used to examine stability index (ST), weight distribution percentages, weight distribution index (WDI), fall index (FI), synchronizationsand spectrum analysis of postural sway under the condition of standing still with eyes open respectively in both groups. Results Frequenciesof spectrum analysis of postural sway in the stroke group were significantly higher than that in normal control group (P<0.05) exceptthe low frequencies. The weight distribution percentages of unaffected foot and WDI of the stroke group were significantly higher thanthe normal control group (P<0.05). ST and synchronizations in the stroke group were worse than the normal control group (P<0.05). In thestroke group, correlations were found between FI and ST, FI and spectrum analysis of postural sway (except the low frequencies), as well asbetween FI and synchronizations (P<0.05). Conclusion Stability index, weight distribution percentages, weight distribution index, synchronizationsand spectrum analysis of postural sway are significantly abnormal in the elderly stroke patients with balance impairment. And theirfall index was found to be correlated to a variety of factors.

ABSTRACT
BACKGROUND: The population of male and female adolescents in China accounts for 1/5. Adolescents have much psychological bewilderment,troublesome and even diseases on sexual issues.OBJECTIVE: To investigate the development status quo and the regulation of adolescents' sexual physiology, sexual psychology, sexual knowledge and sexual education.DESIGN: A cross-sectional survey by employing students of junior high school as subjects.SETTING: A clinic for adolescent of a tertiary hospital.PARTICIPANTS: Totally 960 students aged between 14 and 19 years old of three junior high schools in Dalian city were selected as subjects between November and December of 2001.METHODS: Self-complied questionnaire was used in the survey based on the sexual psychological education situation scale for junior and senior high school students. Classes were randomly selected for anonymous survey based on voluntary principle.Answers to sex-related questions and differences between male and female students.RESULTS: The average age of menarche in female students was 12.96years old and the average age of first emission in male students was 13.89years old, which were consistent with the results of similar national researches. The incidence and frequency of masturbation and sexual impulse was significantly higher in males than females. There were significant differences in sexual concept and the understanding of sexual knowledge between males and females. The desire to affiliate with the opposite sex was far more than the real occurrence.CONCLUSION: The understanding of sexual knowledge in adolescent is not satisfied. Students are also not satisfied with the sexual education provided by their schools. Hence, school sexual education for adolescents should be enhanced with the involvement of community.
