  • Purpose: This study investigated whether the strength imbalance between two muscles can affect the score of EMG based biofeedback game, and whether the EMG based biofeedback game score can be used as predictable indicator of the degree of muscle balance alternating the conventional strength measuring equipment. Methods: 40 participated in this study. Biodex was used to measure the peak torque/weight in order to calculate the muscle strength balance index between plantar flexor and dorsiflexor of ankle joint. And muscle balance index (MBI) was calculated. The EMG biofeedback game scores of dorsiflexor and plantar flexor were acquired, so that the EMG electrodes were attached at tibialis anterior and gastrocnemius. The relationship between the game score and the muscle balance index were analyzed. Results: There was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the peak torque/weight of plantar flexor (r=-0.70). And there was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the game score of plantar flexor (r=-0.83). Conclusion: The EMG biofeedback game score had significant relationship with muscle imbalance at ankle joint, so it seems that the game score can be used for predicting the degree of muscle imbalance as a parameter.

  • PURPOSE: The purpose of this study was to establish the reliability and validity of the Wheelchair User's Shoulder Pain Index (WUSPI), which was translated into Korean for long-term wheelchair users. This index measured 15 functional activities, including transfer, self-care, wheelchair mobility and general activities. METHODS: To assess test-retest reliability, 23 long-term wheelchair users completed this self-administered index twice within the same day. Reliability was determined by the intraclass correlation coefficient (ICC), and Cronbach's alpha was used to measure internal consistency. To examine concurrent validity, 21 long-term wheelchair users completed the questionnaire, and we examined the correlation between the index score and the shoulder range of motion measurements. RESULT: The results showed that the intraclass correlation for test-retest reliability of the total index score ranging from .88 to .99 was good to excellent. Additionally, Cronbach's alpha was .96. The internal consistency indicated excellent. Concurrent validity showed negative correlations of total index score to range of motion measurements of shoulder flexion (rho=-.58), extension (rho=-.09), abduction (rho=-.59), external rotation (rho=-.07) and internal rotation (rho=-.3), suggesting a relationship of total index score to loss of shoulder range of motion. CONCLUSION: The Korean WUSPI shows not only high reliability and internal consistency, but also concurrent validity with loss of shoulder flexion and abduction.

  • Purpose: The purpose of this study was to evaluate resilience of children with cancer and their mothers. This study aims to identify the main factors behind the resilience of these patients and their mothers. Method: To measure the resilience of cancer patients, Kim's (2002) resilience scale was utilized. The Korean Family Functioning Scale revised by Chae (2004) was used to calculate the resilience of mothers. Respondents for this study consist of 60 pediatric cancer patients and their mothers. Data was collected a Medical Center in Seoul, Korea. Descriptive statistics, t-test, ANOVA, and the Pearson's correlation coefficients were used for data analysis. Results: The resilience mean of pediatric cancer patients is 98.32 ($3.09{\pm}0.03$) and of mothers is 64.95 ($3.08{\pm}0.25$). There appears to be a high resilience in pediatric cancer patients who hold religious beliefs. Similarly, there is a high resilience for mothers who are employed. And there is a significant positive correlation between the resilience of pediatric cancer patients and their mothers. Conclusions: As the study indicates that there is a definite relationship between the resilience of pediatric cancer patients and their mothers, it is vital to improve the condition of both the patient and his mother to augment the healing process.

  • Purpose: This study is a descriptive research study to identify the relationship between the experience of verbal abuse, compassion fatigue, and work engagement among nurses in the emergency unit. Methods: Study subjects were 107 nurses working in a university hospital in Gyeonggi-Do. The instruments used were a verbal abuse checklist, a subscale of the Professional Quality of Life Scale used to measure compassion fatigue, and the Utrecht Work Engagement Scale. The data were analyzed using the IBM SPSS version 22.0 program for independent t-test, one-way ANOVA, and Pearson's correlation coefficients. Results: Emergency nurses experienced more verbal abuse and compassion fatigue than nurses in other departments, and the level of work engagement was low. There was a positive correlation between experience of verbal abuse and compassion fatigue and a negative correlation between both of these variables and work engagement. Particularly, verbal abuse appeared in the order of nurses, patients & caregivers, and doctors. This means there were serious problems with communication with nurses. Conclusion: In order to reduce verbal abuse, it is necessary to establish a communication culture of mutual respect between nurses, medical staff, patients & caregivers. Moreover, a compassion fatigue management program is needed to reduce emotional fatigue.
