Adjacent segment pathology of the cervical spine: A case report.

Adjacent segment pathology (ASP) refers to degenerative changes at segments immediately contiguous to previous spinal fusion. Its pathophysiology is hypothesized as being possibly due to altered biomechanical stresses on adjacent levels following spinal fusion or due to patient propensity to develop progressive degenerative change. This case report describes a 61-year-old female who presented with neck pain and cervical radiculopathy attributed to an anterior cervical discectomy and spinal fusion performed for degenerative disc disease 30 years earlier. ASP was seen on magnetic resonance imaging (MRI) and radiograph. Treatment consisted of cervical manipulation, soft-tissue mobilization, flexion-distraction decompression, and therapeutic ultrasound to release restriction and restore muscle strength. Following 34 sessions of chiropractic intervention, her symptoms were resolved. Patients with ASP will have ongoing shared care between general practitioners and secondary or tertiary care pain units. This report aims to build a shared understanding from the wider vision of ASP and help primary practitioners to manage ASP effectively.

Cervicogenic dysphagia associated with cervical spondylosis: A case report and brief review.

Dysphagia (swallowing difficulty) is most often related to another health problems, including brain or spinal cord injury, neurological damage, neuromuscular disorders, and anatomical conditions. Dysphagia can have detrimental effects on pulmonary health and also impact nutritional intake. The right treatment depends on the cause established. Cervicogenic dysphagia is a cervical cause of difficulty in swallowing. This report describes a 53-year-old female patient with sore throat, swallowing difficulty for solids, and acid reflux for 2 years. Radiographs revealed anterior osteophytic lipping and kyphosis of the cervical spine and thoracolumbar (right convex) scoliosis. After 6 months of chiropractic treatment, her complaints and spinal deformity were obviously resolved. Our case report is unique in that the patient had an unusual presentation, i.e. cervical osteophytes, cervical kyphosis, and thoracolumbar scoliosis, which are all contributable causes of dysphagia. Correction of spinal deformity could result in positive treatment outcomes in selected patients with symptoms of cervicogenic dysphagia.

Evaluation of the user seal check on gross leakage detection of 3 different designs of N95 filtering facepiece respirators.

BACKGROUND: The use of N95 respirators prevents spread of respiratory infectious agents, but leakage hampers its protection. Manufacturers recommend a user seal check to identify on-site gross leakage. However, no empirical evidence is provided. Therefore, this study aims to examine validity of a user seal check on gross leakage detection in commonly used types of N95 respirators. METHODS: A convenience sample of 638 nursing students was recruited. On the wearing of 3 different designs of N95 respirators, namely 3M-1860s, 3M-1862, and Kimberly-Clark 46827, the standardized user seal check procedure was carried out to identify gross leakage. Repeated testing of leakage was followed by the use of a quantitative fit testing (QNFT) device in performing normal breathing and deep breathing exercises. Sensitivity, specificity, predictive values, and likelihood ratios were calculated accordingly. RESULTS: As indicated by QNFT, prevalence of actual gross leakage was 31.0%-39.2% with the 3M respirators and 65.4%-65.8% with the Kimberly-Clark respirator. Sensitivity and specificity of the user seal check for identifying actual gross leakage were approximately 27.7% and 75.5% for 3M-1860s, 22.1% and 80.5% for 3M-1862, and 26.9% and 80.2% for Kimberly-Clark 46827, respectively. Likelihood ratios were close to 1 (range, 0.89-1.51) for all types of respirators. CONCLUSIONS: The results did not support user seal checks in detecting any actual gross leakage in the donning of N95 respirators. However, such a check might alert health care workers that donning a tight-fitting respirator should be performed carefully.

Feasibility and effectiveness of a Chen-style Tai Chi programme for stress reduction in junior secondary school students.

Stress is common in junior secondary school students (JSSS). This study aimed to determine the feasibility and effectiveness of a Chen-style Tai Chi programme for stress reduction in JSSS. A non-equivalent pre-test/post-test control group design was adopted, and a convenience sample of 69 JSSS was recruited. The experimental group (n = 32) joined a Chen-style Tai Chi programme, which included 10 sessions of 80-minute Tai Chi training (one session per week). The control group (n = 37) proceeded with self-study. Participants' stress levels were assessed using the Perceived Stress Scale. Feasibility was determined as the percentage of participants completing and attending the programme. Effectiveness was measured as the significant difference in changes in stress levels before and after the intervention between the two groups. Results preliminarily supported that the programme was feasible for JSSS. Completion rate was 100%, and attendance rate was 90%. However, no significant difference was noted in changes in stress levels before and after the intervention between the two groups. The potential health benefits of Tai Chi could not be detected owing to the restrictions imposed by the research setting and study limitations. The present study represents initial efforts in this direction and serves as reference for future study.

Pedometer-determined physical activity and body composition in Chinese working adults.

PURPOSE: Overweight and obesity are prevalent public health problems in many developed and developing regions. Despite extensive documentation on the health benefits of physical activities, little is known about the level of physical activity in the Hong Kong Chinese population. Working adults, in particular, deserve primary attention because they account for the largest proportion of Hong Kong society. The purposes of this study were to investigate pedometer-determined physical activity and examine the associations between physical activity and body composition variables among Chinese working adults in Hong Kong. DESIGN: This study adopted a descriptive cross-sectional design. METHODS: A quota sample of 913 working adults from nine major occupational categories was recruited. Demographic characteristics and body composition parameters (weight, height, and waist and hip circumferences) were assessed. Body mass index and waist-to-hip ratio were then calculated. Physical activity was measured in terms of daily walking steps using a pedometer over 1 week. Participants were then categorized as "inactive,""somewhat active," or "regularly active." Descriptive and inferential statistics (analysis of variance, t test, and χ(2) test) were used appropriately. FINDINGS: Of the 913 participants, 893 returned complete step count records. The completion rate was 97.8%. Participants on average walked 8,661 steps per day, suggesting a "somewhat active" populace. Significant differences were found between the group "regularly active" and "inactive" in most of the body composition parameters. However, a significant weak correlation was found between physical activity and body mass index (r= 0.12, p= .001). Such findings deserve further investigation. CONCLUSIONS: The Chinese working adults in Hong Kong were found to be somewhat active in physical activity. CLINICAL RELEVANCE: Findings pose implications for healthcare professionals who are responsible for health promotion in the Asian community setting. Leisure-type physical activity, such as walking, can be incorporated into daily routines.

The psychosocial effect of Tai Chi on nursing home residents.

AIM: To determine the psychosocial effect of Tai Chi on nursing home residents. BACKGROUND: Moving into a nursing home usually imposes a certain degree of psychosocial challenge to older people. However, there is limited evidence suggesting a promising intervention that can promote the psychosocial health for this group. Although previous studies suggest that Tai Chi has the potential to enhance psychosocial well-being, existing evidence is deemed scarce and thus imposes a limitation on drawing out conclusions on this matter. DESIGN: Non-equivalent pretest-posttest control group design. METHODS: A convenience sample of 139 residents from six nursing homes in Hong Kong was recruited for this study. The experimental group (n = 66) participated in a 26-week Tai Chi programme, while the control group (n = 73) continued its normal daily activities. The outcome measures included state self-esteem, the physical and mental component of health-related quality of life, social support network and social support satisfaction. Resident satisfaction was identified as a covariate because it demonstrated significant correlation with the outcome variables and, likewise, showed significant difference between the two study groups at baseline. Doubly multivariate analysis of covariance was performed to examine the effect of the intervention. RESULTS: Results indicate significant Group x Time interactions, with the experimental group experiencing significant improvement in the composite outcome of state self-esteem, the physical component of health-related quality of life and the mental component of health-related quality of life across the 26-week study period [F(6, 131) = 2.61, p = 0.02)]. No significant changes were detected regarding the effect of the Tai Chi programme on social support. CONCLUSION: Tai Chi practice is beneficial for nursing home residents. RELEVANCE TO CLINICAL PRACTICE: Tai Chi has unique characteristics that are particularly suitable in the practice of health exercise for nursing home residents. The inclusion of Tai Chi in residential care practice for older people is recommended.

Evaluating the effect of childbirth education class: a mixed-method study.

AIM: To examine Chinese women's satisfaction with and the perceived effect of childbirth education class on their labour experience. BACKGROUND: Attending childbirth education classes is a common activity for pregnant women. Nonetheless, evidence reveals that evaluation of the effects of childbirth education classes is inconsistent. Moreover, women's perceived effect of these classes has not been systematically examined. METHODS: This two-phase study adopted a mixed-method design with Donadedian's model as the theoretical framework. In Phase One, a random sample of 40 Chinese women was invited to complete a questionnaire after attending a childbirth education class. The questionnaire was focused on their satisfaction with specific aspects of the class. Descriptive statistics were performed to summarize participants' response. In Phase Two, six of the original 40 women were purposely selected for a semi-structured interview pertaining to the perceived effect of the childbirth education class on their labour experience. Thematic analysis was conducted on the interview data. FINDINGS: The participants expressed overall satisfaction with the class. The area that satisfied them the most was the performance of the midwife. The areas that satisfied them the least were the date, length, size and time of the class. Three themes emerged from the interview data, namely, 'learning about labour', 'contributing to a smooth labour process' and 'coping with uncertainty and handling anxiety. CONCLUSION: This study supports using a mixed-method approach to evaluate client education activity, and highlights the importance of cultivating positive coping measures among the Chinese women after attending childbirth education class when facing childbirth-related anxiety.

Tai Chi and health-related quality of life in nursing home residents.

PURPOSE: Health-related quality of life (HRQOL) that is good is regarded as the goal of elderly residential care. However, limited evidence exists indicating a promising intervention that can achieve this goal. The aim of this study is to examine the effect of Tai Chi on HRQOL in nursing home residents. DESIGN: A nonequivalent pretest-posttest control-group design. METHODS: A convenience sample of 139 residents from six nursing homes in Hong Kong was used. The experimental group (n=66) joined a 26-week Tai Chi program, while the control group (n=73) continued with usual daily activities. The physical and mental components of HRQOL were designated as the dependent variables. Resident satisfaction was considered as a covariate. Doubly multivariate repeated measures analysis of covariance was done to examine the intervention effect. FINDINGS: After adjusting for the confounding effect of resident satisfaction, a statistically significant difference (p<0.05) in the physical and mental components of HRQOL between the experimental and control groups was found. Findings showed significant improvement in HRQOL after residents practiced Tai Chi. CONCLUSIONS: These investigators contribute additional knowledge about the health benefits of Tai Chi among nursing home residents and indicates support for its use in this population to improve HRQOL. CLINICAL RELEVANCE: Tai Chi has unique characteristics as a health exercise that is particularly suitable for nursing home residents. The inclusion of Tai Chi exercise in elderly residential care practice is recommended.

Validation of the Chinese version of the satisfaction with the nursing home instrument.

AIM: To assess the psychometric properties of the Chinese version of the Satisfaction with the Nursing Home Instrument. BACKGROUND: Resident's satisfaction has been regarded by the literature as a gold standard for quality of nursing home care. Accurate assessment of resident's satisfaction can provide valuable information for implementation of quality nursing home care. However, there is not a validated Chinese tool to serve the purpose. DESIGN: A cross-sectional descriptive survey design. METHODS: Content validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by the use of expert panel. Construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was determined by assessing the correlation between satisfaction with other theoretically related constructs. Internal consistency and stability of the Chinese version of the Satisfaction with the Nursing Home Instrument were determined by Cronbach's method and two-week test-retest reliability. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by confirmatory factor analysis. Testing was performed on a cluster sample of 330 residents from 16 nursing homes in Hong Kong. RESULTS: The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated good content validity by having content validity index of 0.93. High construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was supported by its significant correlation with depression (r = -0.42, P = 0.000), health-related quality of life (physical component) (r = 0.16, P = 0.042), health-related quality of life (mental component) (r = 0.41, P = 0.000) and global quality of care (r = 0.49, P = 0.000). The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated satisfactory internal consistency and good stability by having Cronbach's alpha of 0.79 and intra-class correlation coefficient of 0.94, respectively. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was not fully supported by confirmatory factor analysis. CONCLUSIONS: The Chinese version of the Satisfaction with the Nursing Home Instrument is a useful instrument for assessing satisfaction of cognitively intact Chinese nursing home residents. Findings provided initial evidence on its validity and reliability. Further empirical testing is recommended to explore its factor structure. RELEVANCE TO CLINICAL PRACTICE: The Chinese version of the Satisfaction with the Nursing Home Instrument can provide guidance to enhance delivery of high-quality nursing home care for the Chinese population.

Predictors of satisfaction among cognitively intact nursing home residents in Hong Kong.

Resident satisfaction is widely recognized as a critical dimension in assessing quality of nursing home care. Although many factors are associated with satisfaction, little is known about the relative importance of these factors in predicting satisfaction. The purpose of this study was to identify the demographic, physiological, psychological, and social predictors of satisfaction in a convenience sample of 175 nursing home residents in Hong Kong. Seventeen resident variables were investigated. Variables that showed significant bivariate associations with satisfaction were entered into the stepwise regression model. Health-related quality of life (mental component), state self-esteem, and social support satisfaction, significantly accounted for 31% of the variance of satisfaction. These findings suggest approaches to tailor care plans to increase resident satisfaction.
