Reliability, Concurrent Validity, and Minimal Detectable Change of Timed Up and Go Obstacle Test in People With Stroke.

OBJECTIVE: The aims of this study were to investigate the psychometric property of the timed Up and Go Obstacle (TUGO) test in people with stroke. DESIGN: Cross-sectional design. SETTING: University based neurorehabilitation laboratory. PARTICIPANTS: Twenty-eight people with stroke and 30 healthy older adults. INTERVENTION: Not Applicable. OUTCOME MEASURES: The TUGO (obstacle heights: 0, 5, 17 cm) test completion times, Fugl-Meyer Assessment (FMA) score, ankle dorsiflexor and plantarflexor muscle strength, Berg Balance Scale (BBS) score, Narrow Corridor Walking Test (NCWT) completion time, timed Up and Go (TUG) test completion time, and Community Integrated Measure. RESULTS: Excellent inter-rater (intraclass correlation coefficient [ICC]=0.999-1.000) and test-retest reliabilities (ICC=0.917-0.975) were found for TUGO test completion times for all obstacle heights. The TUGO test completion times for all obstacle heights were significantly correlated with NCWT and TUG test completion times (r=0.817-0.912). Only TUGO test completion times for 0 and 5 cm obstacle heights showed significant correlations with BBS scores (r=-0.518 to -0.534), while the TUGO test completion time for the 17 cm obstacle height correlated significantly with FMA scores. The minimal detectable change and optimal cut-off values for TUGO test completion times for the 0, 5, and 17 cm obstacle heights were 2.54, 3.60, and 3.07 s, and 14.69, 14.76, and 16.10 s, respectively. CONCLUSION: The TUGO test is a reliable, valid, and easy-to-administer clinical measure to discriminate between people with stroke and healthy older adults.

Frailty is associated with pain and cognitive function in older people in post-acute care settings.

BACKGROUND: To describe pain, cognitive function, and frailty of older people in post-acute care settings and examine the association between the three elements. METHODS: This cross-sectional study involved 142 participants from a rehabilitation ward and a geriatric day centre. Pain, cognitive function and frailty were assessed using Brief Pain Inventory, Abbreviated Mental Test, and 5-item Frail Scale respectively. RESULTS: Participants were mostly women (51.7%) with a mean age of 76.5 (SD 7.8). Mean scores for pain, cognition, and frailty were 9.0 ±â€¯1.0, 4.0 ±â€¯2.8, and 2.2 ±â€¯1.2, respectively. Cognition had a significant inverse association with frailty (ß = -0.160, p = 0.047), and pain had a significant positive association with frailty (ß = 5.122, p < 0.001). This linear regression model explained a variance of 0.269. CONCLUSIONS: The study demonstrated the association between pain, cognitive function, and frailty. In predicting frailty, however, more studies are required to determine the predictive value and cut-off points for pain and cognitive measures.

Pain situations among working adults and the educational needs identified: an exploratory survey via WeChat.

OBJECTIVES: The aim of this study is to 1) investigate the pain situation among working adults in China; 2) explore the self-initiate pain reliving strategies applied by working adults; and 3) collect people's interests and suggestions to the topics of the online pain education program. METHODS: This is an exploratory survey through WeChat. The study was conducted from May 2018 to December 2018. Participants were recruited following the snowball sampling. In total of 664 people were recruited and 502 satisfied the criteria. SPSS was used for data analysis. Descriptive statistical analysis were used to present the utilization of pain treatments and suggested topics. Chi-square test, independent multiple logistic regression and Spearman's correlation were used to analysis the data. RESULTS: The overall incidence of pain among the participants is 45% and higher among female (63%) than male (37%). Neck (68.72%, 4.10 ± 2.31), shoulder (62.56%, 3.78 ± 2.41) and head (49.34%, 4.23 ± 2.52) are reported as the most common and severe pain sites. Working is affected by pain and the results show that there is a negative correlation between pain intensity and work (rs = - 0.194) among the working population. Non-pharmacological treatments (55.77%) were chosen more by pain suffers. Totally 63.39% of participants show interests in the online pain education program and physical and psychological impact of pain is the most suggested topic (22.51%). CONCLUSION: The pain prevalence is high among working adults in China. Impact of pain on work is a significant problem for the working adults. It is important to identify people at risk and deliver timely intervention to reduce pain. People showed their willingness in joining the online program. Therefore, future online pain education program can be developed.

The sitting and rising test for assessing people with chronic stroke.

[Purpose] To investigate the inter-rater and test-retest reliability of the sitting-rising test (SRT), the correlations of sitting-rising test scores with measures of strength, balance, community integration and quality of life, as well as the cut-off score which best discriminates people with chronic stroke from healthy older adults were investigated. [Subjects and Methods] Subjects with chronic stroke (n=30) and healthy older adults (n=30) were recruited. The study had a cross-sectional design, and was carried out in a university rehabilitation laboratory. Sitting-rising test performance was scored on two occasions. Other measurements included ankle dorsiflexor and plantarflexor strength, the Fugl-Meyer assessment, the Berg Balance Scale, the timed up and go test, the five times sit-to-stand test, the limits of stability test, and measures of quality of health and community integration. [Results] Sitting-rising test scores demonstrated good to excellent inter-rater and test-retest reliabilities (ICC=0.679 to 0.967). Sitting-rising test scores correlated significantly with ankle strength, but not with other test results. The sitting-rising test showed good sensitivity and specificity. A cut-off score of 7.8 best distinguished healthy older adults from stroke subjects. [Conclusions] The sitting-rising test is a reliable and sensitive test for assessing the quality of sitting and rising movements. Further studies with a larger sample are required to investigate the test's validity.

Reliability and validity of the sideways step test and its correlation with motor function after stroke.

[Purpose] This study investigated the intra-rater, inter-rater and test-retest reliability of the sideways step test (SST), its correlation with other indicators of stroke-specific impairment, and the cut-off count best discriminating subjects with stroke from their healthy counterparts. [Subjects and Methods] Forty-three subjects with chronic stroke and 41 healthy subjects older than 50 years participated in this study. The SST was administered along with the Fugl-Meyer motor assessment for the lower extremities (FMA-LE), the five-times sit to stand (5TSTS) test, the Berg Balance Scale (BBS), the movement velocity (MVL) by the limits of stability (LOS) test, the ten-metre walk (10mW) test, the timed "Up and Go" (TUG) test and the Activities-specific Balance Confidence (ABC) scale. [Results] The SST showed good to excellent intra-rater, inter-rater and test-retest reliability. The SST counts correlated with 5TSTS times, 10mW times, TUG times, and the FMA-LE and BBS scores. SST counts of 11 for the paretic leg and 14 for the non-paretic leg were found to distinguish the healthy adults from subjects with stroke. [Conclusion] The sideways step test is a reliable clinical test, which correlates with the functional strength, gait speed, and functional balance of people with chronic stroke.

The effectiveness of physical exercise training in pain, mobility, and psychological well-being of older persons living in nursing homes.

Pain is common in the aging population, particularly among older residents of nursing homes. It has been found that 50% of older people living in the community have been experiencing chronic pain, and the number increased to 80% for older residents of nursing homes. Exercise is an effective non-pharmacological intervention that can reduce pain and improve physical and psychological functions. A quasi-experimental study with a pretest-posttest control group designed was conducted to evaluate the effects of a physical exercise program (PEP) on older residents of nursing homes who have chronic pain. Three-hundred-ninety-six older residents with chronic pain were recruited from 10 nursing homes run by non-governmental organizations in Hong Kong. The average age of the older residents was 85.44 ± 6.29. Five nursing homes were randomized to the experimental group with PEP (n = 225, age = 85.45 ± 6.25); the other five nursing homes were randomized to the control group without the PEP (n = 171, age = 85.44 ± 6.35). PEP was an eight-week training program given by a physiotherapist and nurses once a week. It consisted of warm-up exercises, muscle strengthening, stretching, balancing, and self-administered massage to acupressure points. At the end of each PEP session, pamphlets with pictures illustrating the "exercise of the day" were given to the older residents of nursing homes as a tool to enhance their self-management skills. The control group received no training during the eight weeks. Upon completion of the PEP, the experimental group experienced a significantly greater reduction in pain intensity from 4.19 ± 2.25 (on an 11 point scale) to 2.67 ± 2.08, as compared to the control group (p < .05). In addition, the psychological well-being (happiness, loneliness, life satisfaction, and depression) of the experimental group was significantly improved (p < .05).

Pain management for older persons living in nursing homes: a pilot study.

Because the prevalence of chronic pain among the elderly in nursing homes is high and decreases their quality of life, effective nonpharmacologic pain management should be promoted. The purpose of this quasiexperimental pretest and posttest control design was to enhance pain management in nursing homes via an integrated pain management program (IPMP) for staff and residents. Nursing staff and residents from the experimental nursing home were invited to join the 8-week IPMP, whereas staff and residents from the control nursing home did not receive the IPMP. Baseline data were collected from nursing staff and residents in both groups before and after the IPMP. The IPMP consisted of eight lectures on pain assessment, drug knowledge,and nondrug strategies for the nursing staff, and 8 weeks of activities, including gardening therapy and physiotherapy exercise, for the residents. There were 48 and 42 older people in the experimental and control groups, respectively. No significant differences were found in their educational level, sleep quality, bowel habits, past and present health conditions, pain conditions and psychologic well-being parameters (p > .05) at baseline. After the IPMP, the experimental nursing staff showed a significant improvement in their knowledge of and attitudes to pain management (p < .05), and the experimental residents reported significantly lower pain scores and used more nondrug strategies for pain relief compared with the control group (p < .05). Moreover, the psychologic well-being parameters, including happiness, loneliness, life satisfaction, and geriatric depression, had significantly improved among the experimental residents (p < .05). The IPMP was effective in enhancing the knowledge and attitudes of nursing staff, as well as reducing pain conditions and enhancing psychologic well-being for older persons in nursing homes.

Health-related profile and quality of life among nursing home residents: does pain matter?

The purpose of this exploratory cross-sectional study was to explore the health-related profile and quality of life among older persons living with and without pain in nursing homes. Ten nursing homes were approached, and 535 older persons were invited to join the study from 2009 to 2011. The nursing home residents' demographic information and information regarding their pain situation and the use of oral analgesic drug and nondrug therapy among the older residents with chronic pain were also collected. Residents' physical health (using the Barthel Activities of Daily Living (ADL) and Elderly Mobility Scores); psychologic health, including happiness, life satisfaction, depression, and loneliness (using the Happiness Scale, the Life Satisfaction Scale, the Geriatric Depression Scale, and the UCLA Loneliness Scale); and quality of life were investigated. Among the 535 nursing home residents, 396 (74%) of them suffered from pain, with mean pain scores of 4.09 ± 2.19, indicating medium pain intensity a remaining 139 (26%) reported no pain. The location of pain was mainly in the knees, back and shoulders. Our results demonstrated that, with the exception of the no-pain group (p < .05), nursing home residents' pain affected both their psychologic health, including happiness, life satisfaction, and depression, and their physical quality of life. Nevertheless, only one-half of the older persons with pain used oral analgesic drug or nondrug therapy to relieve their pain. Pain had a significant impact on their mobility and ADL, was positively correlated with happiness and life satisfaction, and was negatively correlated with loneliness and depression. Pain management is a high priority in elderly care; as such, innovative and interdisciplinary strategies are necessary to enhance quality of life particularly for older persons living in nursing homes.

Motivational interviewing and exercise programme for community-dwelling older persons with chronic pain: a randomised controlled study.

AIMS AND OBJECTIVES: To examine the effectiveness of an integrated motivational interviewing and physical exercise programme on pain, physical and psychological function, quality of life, self-efficacy, and compliance with exercise for community-dwelling older persons with chronic pain. BACKGROUND: Chronic pain is common among older persons. Indeed, motivation for managing pain is poor, and may cause negative consequences. Motivational interviewing maybe effective in treating chronic pain. DESIGN: Single-blinded randomised control study. METHODS: Older persons with chronic pain (n = 56) were recruited from two elderly community centres. They were blinded from the group allocation. The programme was conducted by an motivational interviewing-trained physiotherapist and registered nurses. Participants in the experimental group received an 8-week integrated motivational interviewing and physical exercise programme, while the control group received regular activities in the centre. Motivational interviewing used open-ended questions to encourage participants to express and recognise their pain and behaviours and professional feedback was given accordingly. Pain intensity, pain self-efficacy, anxiety, happiness, depression, mobility and quality of life were measured before and after the motivational interviewing and physical exercise programme. Attendance and compliance rate of the programme was calculated in the experimental group. RESULTS: Significant improvements in pain intensity, pain self-efficacy, anxiety, happiness and mobility after the motivational interviewing and physical exercise programme (all p < 0.05) for experimental group, while no significant improvement in control group except on the happiness scale. Regarding group differences in the outcome measures, the change scores on pain intensity, state anxiety and depression were significantly better in the experimental group. CONCLUSION: Motivational interviewing and physical exercise programme is effective in improving pain, physical mobility, psychological well-being and self-efficacy for community-dwelling older persons with chronic pain. RELEVANCE TO CLINICAL PRACTICE: Motivational interviewing is a feasible counselling technique whose content can be modified based on target group to change maladaptive behaviours, elicit ambivalences and enhance self-efficacy for making changes. Thus, promoting motivational interviewing and physical exercise programme to older persons with pain is effective and important.

A music-with-movement exercise programme for community-dwelling older adults suffering from chronic pain: A pilot randomized controlled trial.

AIM: This study developed, implemented and tested the effectiveness of a music-with-movement exercise programme in improving the pain situations of older adults with chronic pain. DESIGN: A pilot randomized controlled trial. METHODS: This was a pilot randomized controlled trial. The intervention was an 8-week music-with-movement exercise (MMEP) programme for older adults with chronic pain recruited in elders' community centres. The control group received the usual care and a pain management pamphlet. Outcome variables were pain intensity, pain self-efficacy and pain interference, depression and loneliness. RESULTS: Seventy-one participants joined this study. Pain intensity was significantly reduced between the experimental group compared to the control group. The experimental group participants reported significant improvements in pain self-efficiency, pain interference and reduced loneliness and depressive symptoms. However, no significant difference was observed between groups.

Assessing the Turning Ability during Walking in People with Stroke Using L Test.

BACKGROUND: The L Test of Functional Mobility (L Test) was developed to assess the advanced mobility, which includes both turning and walking ability. This study aimed to evaluate (1) the intra-rater reliability of the L Test in four turning conditions, (2) the correlation with other stroke-specific impairment for community-dwelling older adults with stroke, and (3) the optimal cut-off completion time of the L Test to distinguish the difference of performance between healthy older adults and people with stroke. METHODS: This is a cross-sectional design. Thirty older adults with stroke and healthy older adults were included. The subjects were assessed by L Test along with other stroke-specific outcomes. RESULTS: The L Test showed excellent intra-rater reliability (ICC = 0.945-0.978) for the four turning conditions. There were significant correlations between L Test completion times and Fugl-Meyer Assessment-Lower Extremity (FMA-LE) scores, Fugl-Meyer Assessment-Upper Extremity (FMA-UE) scores, Berg Balance Scale (BBS) score, and Timed Up and Go (TUG) Test scores. The cut-off of the L Test was established as 23.41-24.13 s. CONCLUSION: The L Test is an easy-to-administer clinical test for assessing the turning ability of people with stroke.

Psychometric properties of Upper-body Dressing Scale in people with stroke.

OBJECTIVES: To investigate the psychometric properties of the Upper-Body Dressing Scale (UBDS), a tool for evaluating upper-body dressing performance in stroke patients. DESIGN: Cross-sectional study. SUBJECTS: Seventy-six chronic stroke patients and 49 healthy older adults. METHODS: UBDS, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Berg Balance Scale (BBS), Timed Up-and-Go Test (TUGT), Limit of Stability (LOS) test, Motor Activity Log (MAL-30), Arm Activity Measure (AAM), 12-item Short Form Health Survey, and Community Integration Measure - Cantonese version were assessed Results: UBDS time and UBDS score demonstrated good to excellent inter-rater and test-retest reliabilities for chronic stroke patients (intraclass correlation coefficient 0.759-1.000). UBDS time correlated significantly with FMA Upper and Lower Extremity, WMFT, and BBS scores, TUGT time, LOS Movement Velocity (affected side), LOS Maximal Excursion (composite), MAL-30 Amount of Use and Quality of Movement (affected side), and AAM (section B) scores (r = -0.61 to 0.63). The minimal detectable changes in UBDS time and UBDS score were 28.67 s and 0, respectively. The cut-off UBDS time and UBDS score were 37.67 s and 7.50, respectively. CONCLUSION: UBDS time is a reliable, sensitive, and specific measurement for assessing upper-body dressing performance in chronic stroke patients.

Reliability and validity of the supine-to-stand test in people with stroke.

OBJECTIVE: To investigate the psychometric properties of the supine-to-stand test in people with stroke. DESIGN: Cross-sectional design. SUBJECTS: Fifty-two people with stroke (mean (standard deviation) age 63.13 (6.09) years; time post-stroke 93.13 (61.36) months) and 49 healthy older adults (61.90 (7.29) months). METHODS: Subjects with stroke were recruited from the community dwelling in Hong Kong and  assessed with the supineto- stand test, Fugl-Meyer Motor Assessment, ankle muscle strength test, Berg Balance Scale, limit of stability test, Timed Up-and-Go Test, Six-Minute Walk Test, Chinese version of Activities-specific Balance Confidence scale, Community Integration Measure (CIM-C), and 12-item Short-Form Health Survey (SF-12) in a university-based rehabilitation laboratory. RESULTS: The supine-to-stand test completion time demonstrated excellent intra-rater, inter-rater and test-retest reliability (intraclass correlation coefficient 0.946-1.000) for the people with stroke. The completion time was significantly negatively correlated with Berg Balance Scale, Six-Minute Walk Test, limit of stability - maximal excursion, and limit of stability - endpoint excursion results (r = -0.391 to -0.507), whereas it was positively correlated with the Timed Up-and-Go test results (r = 0.461). The optimal cut-off supine-to-stand test completion time of 5.25 s is feasible for a clinical measure to distinguish the performance of people with stroke from healthy older adults (area under the curve = 0.852, sensitivity = 81.1%, specificity = 84.0%). CONCLUSION: The supine-to-stand test is a reliable, sensitive, specific and easy-to-administer clinical test for assessing the supine-to-stand ability of people with stroke.

Postoperative pain experience and barriers to pain management in Chinese adult patients undergoing thoracic surgery.

AIMS: The purpose of this study was (1) to explore postoperative pain experience among Chinese thoracotomy patients during hospitalisation; (2) to identify patient-related barriers to pain management; and (3) to explore how these barriers were related to patients' pain experience. BACKGROUND: Major thoracotomy causes severe pain and extreme stress for patients. Unrelieved postoperative pain leads to high risks of postoperative complications and chronic post-thoracotomy pain syndrome, compromising the quality of life for those patients. DESIGN: Cross-sectional design. METHODS: A tertiary general hospital in mainland China was selected for this study. A total of 94 patients undergoing scheduled major thoracotomy operations participated in the study. All patients completed Brief Pain Inventory-Chinese version, the Barrier Questionnaire-Taiwan Form Surgical version and a demographic questionnaire. RESULTS: Patients suffered moderate to severe pain and experienced extremely high interferences with daily activities after major thoracotomy operation. Patients reported the four highest barrier scores in the subscale of Barrier Questionnaire-Taiwan Form Surgical version were fear of tolerance, inhibition of wound healing, time intervals and distracting the physician from treating the disease. Patient's demographic data had no significant impact on their concerns about communicating pain and using of analgesics with exception of the subscale 'fatalism' of the Barrier Questionnaire-Taiwan Form Surgical version in patients with higher education levels or patients with 'non-farmer' occupation. However, there were no significant correlations indicated either between Barrier Questionnaire-Taiwan Form Surgical version score and pain severity or pain interference. CONCLUSIONS: Patients were underexposure of pain treatment after thoracotomy operation in the study, while patients' concerns about reporting pain and using analgesics had minimal impacts on their pain experience. RELEVANCE TO CLINICAL PRACTICE: Education approach for patients is inadequate to improve the status of unrelieved postoperative pain. Appropriate pain management regime together with attentive nursing care should be provided to achieve better pain relief for Chinese patients.

Translation and Initial Validation of the Chinese (Cantonese) Brief 2-Way Social Support Scale for Use in People with Chronic Stroke.

Background: Social support is important for stroke rehabilitation. Conventionally, social support is evaluated from the level of support received. However, the bidirectional support hypothesis postulated that self-perceived social support is optimized if individuals provide and receive social support in a balanced manner. The Brief 2-Way Social Support Scale (Brief 2-Way SSS) is a social support instrument measuring the reciprocity of receiving and giving emotional and instrumental social support. Objective: (1) To translate and culturally adapt the English version of the Brief 2-Way SSS into Chinese (Cantonese) (Brief 2-Way SSS-C), (2) to report the results of validation of the Brief 2-Way SSS-C, and (3) to investigate the level of social support in people with stroke in Hong Kong. Methods: The Brief 2-Way SSS-C was produced following the standard forward-backward translation model. People with stroke (n = 109) and age-matched controls (n = 53) were recruited through a university-affiliated neurorehabilitation laboratory. Results: The Brief 2-Way SSS-C demonstrated excellent content validity, acceptable to good internal consistency (Cronbach's alpha of 0.74-0.88), and good test-retest reliability (intraclass correlation coefficient of 0.76-0.81). There were no ceiling or floor effects, and the MDC95 across all subscales was 4. The Brief 2-Way SSS-C subscales had significant correlations with various health-related outcome measures. People with stroke had a lower level of social support than the age-matched healthy controls. Conclusions: The Brief 2-Way SSS-C is a culturally relevant, reliable, and valid outcome measure for the level of social support in community-dwelling people with stroke.

The Predictive Role of Hand Section of Fugl-Meyer Assessment and Motor Activity Log in Action Research Arm Test in People With Stroke.

Background: Recent findings of clinical studies have demonstrated a significant positive relationship between Fugl-Meyer Assessment of upper extremity score and the action research arm test (ARAT) score in people with stroke. Although the motor activity log (MAL) can assess the self-perception of motor performance, which can affect the performance of the upper limb, the relationship between MAL score and ARAT score still remains unclear. The objective of this study is to quantify the independent contribution of MAL score and FMA-hand score on the ARAT score in people with stroke. Methods: This is a cross-sectional study. There were a total of 87 subjects (50 males, 37 females; mean age = 61.12 ± 6.88 years, post-stroke duration=6.31 ± 2.84 years) included in this study. Self-perceived performance in using the paretic limb was measured by MAL, including subscale of the amount of usage (MAL-AOU) and quality of movement (MAL-QOM). Functional performance of the upper limb was measured by action research arm test (ARAT). Upper limb motor control of the hand was measured by hand section of Fugl-Meyer assessment (FMA-hand). Results: The result showed that MAL-QOM (r = 0.648, p < 0.001), MAL-AOU (r = 0.606, p < 0.001), FMA-hand scores (r = 0.663, p < 0.001), and the use of a walking aid (r = -0.422, p < 0.001) were significantly correlated with the ARAT scores. A total 66.9% of the variance in the ARAT scores was predicted by the final regression model including MAL-QOM, MAL-AOU, FMA-hand scores, and walking aid. The FMA-hand score was the best predictor of ARAT scores, which can predict a 36.4% variance of ARAT scores in people with stroke, which controlled the effect of using a walking aid. After controlling for use of a walking aid and FMA-hand scores, the multiple linear regression modeling showed that MAL-QOM and MAL-AOU scores could also independently predict an additional 10.4% of the variance in ARAT scores. Conclusion: In addition to the FMA-hand score, the MAL score was significantly correlated with the ARAT score. Improving self-perceived performance should be one goal of rehabilitation in people with stroke. Further work developing and testing techniques to do so is clearly warranted.

A Dyadic Pain Management Program for Community-Dwelling Older Adults with Chronic Pain: Study Protocol for a Cluster Randomized Controlled Trial.

Community-dwelling older adults suffer from chronic pain. Pain negatively affects their physical and psychosocial wellbeing. The majority of pain management education and programs focus only on older adults. Their informal caregivers should be involved in pain management. A dyadic pain management program for reducing pain and psychological health symptoms, and improving pain self-efficacy, quality of life, and physical function in older adults is proposed for evaluation of its effectiveness. This will be a cluster randomized controlled trial. Community-dwelling older adults aged 60 or above and their informal caregivers will be recruited. The dyadic pain management program will be an eight-week group-based program. The participants in the experimental group will receive four weeks of center-based, face-to-face activities and four weeks of digital-based activities via a WhatsApp group. The control group will receive the usual care and a pain management pamphlet. Data will be collected at baseline, and at the eighth-week and sixteenth-week follow-up session. The outcome measurements will include pain intensity, pain self-efficacy, perceived quality of life, depression, anxiety, and stress levels. Data on the caregiver burden will be collected from the informal caregivers. Because of the COVID-19 pandemic, all social activities have been suspended. In the near future, as the pandemic subsides, the dyadic pain management program will be launched to benefit community-dwelling older adults and informal caregivers and to reduce their pain and the care burden, respectively.

Psychometric Properties of the Trail Walking Test for People With Stroke.

Objective: To investigate (i) the inter-rater and test-retest reliability of the trail walking test (TWT) and the minimum detectable change in the TWT completion time; (ii) the correlations between the TWT completion time and stroke-specific impairments; and (iii) the cutoff TWT completion time to distinguish between people with stroke and healthy older adults according to dual-tasking ambulation ability. Design: Cross-sectional study. Setting: University-based rehabilitation center. Participants: In total, 104 people with stroke and 53 healthy older adults. Main Outcome Measures: The TWT, the Fugl-Meyer Assessment of Lower Extremity (FMA-LE), the ankle muscle strength test, the limit of stability (LOS) test, the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), and the Community Integration Measure (CIM). Results: The mean TWT completion time in subjects with stroke was 124.906 s. The TWT demonstrated excellent inter-rater reliability [intraclass correlation (ICC) = 0.999] and good test-retest reliability (ICC = 0.876) in people with stroke. The TWT performance demonstrated significant negative correlations with the FMA-LE scores (r = -0.409), LOS movement velocity (affected and unaffected sides; r = -0.320 and -0.388, respectively), and LOS endpoint excursion (affected and unaffected sides; r = -0.357 and -0.394, respectively); a significant positive correlation with the LOS reaction time (affected side; r = 0.256); a moderate negative correlation with the BBS scores (r = -0.72); and an excellent positive correlation with the TUG completion time (r = 0.944). The receiver operating characteristic curve analysis revealed that an optimal cutoff of 69.61 s for the TWT completion time had an outstanding diagnostic power to distinguish between people with stroke and healthy older adults (area under the curve = 0.919) with high sensitivity (88.5%) and specificity (83.0%). Conclusion: Results of our preliminary study demonstrated that the TWT is a reliable, valid, sensitive, and specific clinical test for evaluating dual-tasking ambulation ability in people with stroke aged 45 years or above and without cognitive impairments. It can differentiate the dual-tasking ambulation ability between people with stroke and healthy older adults.

Physical exercise: does it help in relieving pain and increasing mobility among older adults with chronic pain?

AIM: To provide a physical exercise programme for older adults living in nursing homes. BACKGROUND: Pain is common among older persons and for those already in long-term care and having difficulty in coping with pain will be at risk of further reducing their optimal independent function. DESIGN: A quasi-experimental single group pretest-posttest design. METHOD: Older persons from a nursing home were invited to join an eight-week physical exercise programme. Each session lasted an hour and sessions were conducted once a week by physiotherapist and nurses. Physical exercise programme consisted of stretching, strengthening, balancing, towel dancing and self-administered massage to various acupressure points. On completion of each session, older persons were given a pamphlet with pictures to illustrate the exercise of the day and they were encouraged to practise these exercises by themselves. Outcome measures including pain intensity, range of movement, activities of daily living and mobility were collected before and after the physical exercise programme. RESULTS: There were 75 older adult participants (57 female and 18 male, mean age 85.14 SD 5.30). Seventy-three percent (n = 55) of them had pain in the previous three months and were referred as pain group, while 25% (n = 20) were no pain group. Pain scores of 4.89 (on a 10-point scale) indicated medium pain intensity before the intervention for the pain group; the location of pain was mainly in the knee, back and shoulder. On completion of the physical exercise programme, there was a significant decrease in pain intensity to 2.89 (SD 2.14) (p < 0.01). There was a significant increase in range of movement in the neck, shoulder, back, hip and knee rotation, flex and abduction (p < 0.01). Mobility level was significantly increased post intervention, yet activities of daily living remained unchanged. CONCLUSIONS: The present study demonstrated the effectiveness of a physical exercise programme in relieving pain and enhancing functional mobility for older persons. Relevance to clinical practice. It is important to educate older persons, especially those living in nursing homes, on the importance of engaging in regular physical exercise and maintaining mobility.

Assessing the fidelity of a peer-led chronic pain management program (PAP).

BACKGROUND: Intervention fidelity is the core component of a well-designed clinical trial and processes that are used to ensure that the study intervention is delivered as planned. It affects the design and implementation of a study as well as the analysis of the results and interpretation of the findings. The objectives of this study are (a) to describe the methods of assessing the intervention fidelity used in the peer-led chronic pain management program (PAP) and (b) to report the findings on the PAP's intervention fidelity. METHODS: To optimize fidelity to the intervention, we used various strategies and measured them in a continuous process using several different approaches: (a) peer volunteer (PV) training workshop, (b) biweekly meetings with the research team, (c) a detailed teaching manual, (d) a fidelity checklist, (e) on-site visits and direct observations, and (f) semi-structured interview. RESULTS: The PVs' attendance was high, and most of them achieved a high level of implementation in following the fidelity checklist. As part of a large clustered RCT, the fidelity assessment was carried out to help determine the effectiveness of the intervention. CONCLUSIONS: Overall, the PVs successfully delivered the intervention, and the results of the study indicate the effectiveness of the PAP. TRIAL REGISTRATION: ClinicalTrials.gov NCT03823495 .
