Tai chi-muscle power training for children with developmental coordination disorder: a randomized controlled trial.

This study compared the effectiveness of tai chi (TC) muscle power training (MPT), TC alone, MPT alone, and no training for improving the limits of stability (LOS) and motor and leg muscular performance and decreasing falls in children with developmental coordination disorder (DCD). One hundred and twenty-one children with DCD were randomly assigned to the TC-MPT, TC, MPT, or control group. The three intervention groups received TC-MPT, TC, or MPT three times per week for 3 months. Measurements were taken before and after the intervention period. The primary outcomes were the LOS completion time and dynamic LOS scores. The secondary outcomes included the Movement Assessment Battery for Children-Second Edition total test score and percentile rank, knee muscle peak force and time to peak force, and the number of falls. None of the interventions affected the LOS test scores. Improvements in the peak forces of the knee extensors and flexors were demonstrated in the TC (p = 0.006) and MPT groups (p = 0.032), respectively. The number of falls also decreased in these two groups (p < 0.001). Thus, clinicians may prescribe TC or MPT for children with DCD to increase their knee muscle strength and reduce their risk of falls.

Influence of pelvic padding and Kinesiology Taping on pain perception, kinematics, and kinetics of falls in female volleyball athletes.

BACKGROUND: Volleyball digging techniques may cause pelvic injuries among female volleyball athletes. Pelvic padding and Kinesiology Taping (KT) may reduce impact force and pain and improve posture during a fall. This study examined the effects of pelvic padding and KT on pain perception, fall kinematics, and kinetics among female volleyball athletes. METHODS: Twenty-four female volleyball athletes were exposed to two pelvic padding scenarios (with and without padding) and two KT conditions (with and without KT applied on the rectus abdominis muscle) during a fall in the forward direction. The maximum impact force during landing and maximum acceleration of the pelvis were registered using a force platform and an accelerometer, respectively. The maximum lumbar (hyper) extension angle, forward reach distance, and total fall time were measured by video analysis. Pain level was quantified using a visual analog scale. RESULTS: The application of pelvic padding (with and without KT) reduced pain when compared to the no padding condition (p < 0.008). Applying KT alone reduced forward reach distance when compared to the 'pelvic padding and KT' condition (p < 0.010). In fact, when both pelvic padding and KT were applied, participants reached further when compared to the 'no pelvic padding and no KT' condition (p < 0.001). No significant main and interaction effects were found in all other outcomes. CONCLUSIONS: Volleyball shorts with pelvic pads are recommended for female volleyball athletes to reduce pain in the digging maneuver and may help to increase their forward reach distance. However, KT is not recommended as it reduces the forward reach distance and cannot reduce pain or improve fall kinematics and kinetics.

Bone Mineral Density, Balance Performance, Balance Self-Efficacy, and Falls in Breast Cancer Survivors With and Without Qigong Training: An Observational Study.

PURPOSE: A deterioration in bone strength and balance performance after breast cancer treatment can result in injurious falls. Therefore, interventions need to be developed to improve the bone strength and balance ability of breast cancer survivors. This cross-sectional exploratory study aimed to compare the bone mineral density (BMD), balance performance, balance self-efficacy, and number of falls between breast cancer survivors who practiced qigong, breast cancer survivors who did not practice qigong, and healthy individuals. METHODS: The study included 40 breast cancer survivors with more than 3 months of qigong experience, 17 breast cancer survivors with no qigong experience, and 36 healthy controls. All the participants underwent dual-energy X-ray absorptiometry scans to measure their lumbar spine, total hip, femoral neck, and total radius BMDs. The participants also underwent a timed one-leg stand test to measure their single-leg standing balance. The participants' balance self-efficacy was assessed using the activities-specific balance confidence scale, and the number of falls experienced by each participant was assessed in a face-to-face interview. RESULTS: The lumbar spine, total hip, femoral neck, and total radius BMDs were similar between the 3 groups ( P > .05). The breast cancer-qigong group outperformed the breast cancer-control group by 27.3% when they performed the one-leg stand test on a foam surface ( P = .025), and they also had a higher balance self-efficacy score ( P = .006). Nevertheless, the numbers of falls were comparable between the 3 groups ( P > .05). CONCLUSION: Qigong may be a suitable exercise for improving the balance performance and balance self-efficacy of breast cancer survivors.

Effects of postexercise ice-water and room-temperature water immersion on the sensory organization of balance control and lower limb proprioception in amateur rugby players: A randomized controlled trial.

BACKGROUND: This single-blinded, three-armed randomized controlled trial aimed to compare the effects of postexercise ice-water immersion (IWI), room-temperature water immersion (RWI), and no water immersion on the balance performance and knee joint proprioception of amateur rugby players. METHODS: Fifty-three eligible amateur rugby players (mean age ±â€Šstandard deviation: 21.6 ±â€Š2.9 years) were randomly assigned to the IWI group (5.3 °C), RWI group (25.0 °C), or the no immersion control group. The participants in each group underwent the same fatigue protocol followed by their allocated recovery intervention, which lasted for 1 minute. Measurements were taken before and after the fatigue-recovery intervention. The primary outcomes were the sensory organization test (SOT) composite equilibrium score (ES) and the condition-specific ES, which were measured using a computerized dynamic posturography machine. The secondary outcome was the knee joint repositioning error. Two-way repeated measures analysis of variance was used to test the effect of water immersion on each outcome variable. RESULTS: There were no significant within- and between-group differences in the SOT composite ESs or the condition-specific ESs. However, there was a group-by-time interaction effect on the knee joint repositioning error. It seems that participants in the RWI group had lower errors over time, but those in the IWI and control groups had increased errors over time. The RWI group had significantly lower error score than the IWI group at postintervention. CONCLUSION: One minute of postexercise IWI or RWI did not impair rugby players' sensory organization of balance control. RWI had a less detrimental effect on knee joint proprioception to IWI at postintervention.

Changes in heart-rate variability of survivors of nasopharyngeal cancer during Tai Chi Qigong practice.

[Purpose] To explore the changes in heart-rate variability (HRV) of survivors of nasopharyngeal cancer (NPC) before, during, and after a Tai Chi (TC) Qigong exercise. [Subjects and Methods] Eleven survivors of NPC participated voluntarily in the study. The heart rate of each participant was measured continuously for 1 minute before the TC Qigong intervention, during the 5-minute TC Qigong intervention, and for 1 minute after the intervention, using a Polar heart-rate monitor. Spectral HRV was expressed in terms of normalised low frequency (LF) power, normalised high frequency (HF) power, and the low frequency/high frequency (LF/HF) power ratio. [Results] Both the LF-power and the HF-power components had significant time effects. However, the time effect of the LF/HF power ratio was not significant. Post hoc contrast analysis revealed a significant decrease in LF power and a concomitant increase in HF power during the 4th minute and 5th minute of the TC Qigong exercise. [Conclusion] Five minutes of TC Qigong exercise was found to improve HRV by increasing HF power and decreasing LF power, but these effects were transient. TC Qigong might be an appropriate exercise for improving the ANS function and psychological and cardiac health of survivors of NPC.

The effects of a 6-month Tai Chi Qigong training program on temporomandibular, cervical, and shoulder joint mobility and sleep problems in nasopharyngeal cancer survivors.

INTRODUCTION: Nasopharyngeal cancer (NPC) survivors often sustain head-neck-shoulder impairments from conventional treatments, which could disturb sleep. This novel study aimed to examine the efficacy of Tai Chi (TC) Qigong in optimizing temporomandibular joint (TMJ), cervical, and shoulder joint mobility and reducing sleep problems in NPC survivors. METHODS: Fifty-two NPC survivors participated in the study. The experimental group (n = 25) received 6 months of TC Qigong training (1.5 h/session; 4 sessions/wk including self-practice) while the control group (n = 27) received no training. Cervical side flexion and rotation, shoulder flexion and horizontal flexion range of motion (ROM), mouth opening capacity (interincisor distance), and sleep problems (Medical Outcomes Study Sleep Scale) were assessed at baseline, mid-intervention (3 months), immediately after TC Qigong training, and at 6-month follow-up. RESULTS: Intention-to-treat analysis revealed improvement in cervical side flexion ROM only (P < .008) and unchanged shoulder and TMJ mobility (P > .008) after the TC Qigong training. Deterioration was observed in shoulder flexion ROM and mouth opening capacity in the no-training controls over time (P < .008). Sleep problems also decreased in the TC Qigong group (P < .008), and this effect was most profound during the follow-up period. In addition, improvement in cervical side flexion ROM was associated with a reduction in sleep problems in the experimental group after TC Qigong training (P < .05). CONCLUSIONS: The 6-month TC Qigong intervention improved neck mobility, maintained TMJ and shoulder joint mobility, and reduced sleep problems for NPC survivors. TC Qigong could be an effective nonpharmacological intervention for managing progressive trismus, chronic neck and shoulder hypomobility, and reducing sleep problems among NPC survivors.

Musculoskeletal strength, balance performance, and self-efficacy in elderly ving tsun chinese martial art practitioners: implications for fall prevention.

Objectives. To (1) compare the bone strength, lower limb muscular strength, functional balance performance, and balance self-efficacy between Ving Tsun (VT) martial art practitioners and nonpractitioners and (2) identify the associations between lower limb muscular strength, functional balance performance, and balance self-efficacy among the VT-trained participants. Methods. Thirty-five VT practitioners (mean age ± SD = 62.7 ± 13.3 years) and 49 nonpractitioners (mean age ± SD = 65.9 ± 10.5 years) participated in the study. The bone strength of the distal radius, lower limb muscular strength, functional balance performance, and balance self-efficacy were assessed using an ultrasound bone sonometer, the five times sit-to-stand test (FTSTS), the Berg balance scale (BBS), and the Chinese version of the activities-specific balance confidence scale, respectively. A multivariate analysis of covariance was performed to compare all the outcome variables between the two groups. Results. Elderly VT practitioners had higher radial bone strength on the dominant side (P < 0.05), greater lower limb muscular strength (P = 0.001), better functional balance performance (P = 0.003), and greater balance confidence (P < 0.001) than the nonpractitioners. Additionally, only the FTSTS time revealed a significant association with the BBS score (r = -0.575, P = 0.013). Conclusions. VT may be a suitable health-maintenance exercise for the elderly. Our findings may inspire the development of VT fall-prevention exercises for the community-dwelling healthy elderly.

Effects of qigong training on health-related quality of life, functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer: a pilot study.

This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a weekly 1.5-hour Qigong training program and an identical home program (three times/week) for six months. The control group received no training. Global health status/QOL, functioning, and cancer-related symptoms were assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires before training began, after three months of Qigong training, at the end of the six-month Qigong intervention (i.e., posttest), and six months posttest. Intention-to-treat analysis revealed no statistically (P > 0.05) or clinically significant improvement in global health status/QOL, functioning, or symptoms in either group. The experimental group had 45.8% fewer sense-related (smell and taste) problems (P < 0.05) but 98.6% more speech-related problems (P < 0.05) than the control group after the Qigong intervention. Qigong training resulted in no apparent improvement in health-related QOL, functionality, or cancer-related symptoms in cancer-free survivors of NPC, except for a possible reduction in smell- and taste-related problems.

Effects of a 6-month Tai Chi Qigong program on arterial hemodynamics and functional aerobic capacity in survivors of nasopharyngeal cancer.

PURPOSE: Survivors of nasopharyngeal cancer (NPC) often sustain cardiovascular complications after conventional cancer treatments. Tai Chi (TC) Qigong training may be a viable way to improve peripheral circulatory status and aerobic capacity in this population. The objective of this study was to evaluate the effects of a 6-month TC Qigong training program on blood flow velocities and resistance, palmar skin temperature, and functional aerobic capacity in survivors of NPC. METHODS: Twenty-five and 27 survivors of NPC volunteered to join the intervention group (mean age, 55.4 ± 7.5 years) and control group (mean age, 58.7 ± 9.5 years), respectively. The intervention group underwent a TC Qigong training program-the modified 18 Forms TC Internal Qigong-for 6 months, while the control group received no training. Peripheral arterial blood flow velocities and resistance, palmar skin temperature, and functional aerobic capacity were measured by a Doppler ultrasound machine, an infrared thermometer, and six-minute walk test, respectively. All outcomes were assessed at baseline, mid-intervention (3-month), post-intervention (6-month), and follow-up (12-month) periods. RESULTS: The TC Qigong group had higher diastolic blood flow velocity (p = 0.010), lower arterial blood flow resistance (p = 0.009), and higher palmar skin temperature (p = 0.004) than the control group after TC Qigong training. However, only the diastolic blood flow velocity was higher in the TC Qigong group than in the control group during the no-training follow-up period (p = 0.032). Additionally, an improvement in functional aerobic capacity was found in the intervention group after TC Qigong training (p < 0.008) but not in the control group over time (p > 0.008). CONCLUSIONS: TC Qigong training may improve peripheral circulatory status and functional aerobic capacity among people treated for NPC. However, this is only a pilot study and future definitive trials are needed to confirm the results. IMPLICATIONS FOR CANCER SURVIVORS: TC Qigong may have enormous potential as a rehabilitation intervention for survivors of NPC to improve arterial hemodynamics and functional aerobic capacity.

Effect of acupuncture on heart rate variability: a systematic review.

AIM: To summarize all relevant trials and critically evaluate the effect of acupuncture on heart rate variability (HRV). METHOD: This was a systematic review with meta-analysis. Keyword search was conducted in 7 databases for randomized controlled trials (RCTs). Data extraction and risk of bias were done. RESULTS: Fourteen included studies showed a decreasing effect of acupuncture on low frequency (LF) and low frequency to high frequency ratio (LF/HF ratio) of HRV for nonhealthy subjects and on normalized low frequency (LF norm) for healthy subjects. The overall effect was in favour of the sham/control group for high frequency (HF) in nonhealthy subjects and for normalized high frequency (HF norm) in healthy subjects. Significant decreasing effect on HF and LF/HF ratio of HRV when acupuncture was performed on ST36 among healthy subjects and PC6 among both healthy and nonhealthy subjects, respectively. DISCUSSION: This study partially supports the possible effect of acupuncture in modulating the LF of HRV in both healthy and nonhealthy subjects, while previous review reported that acupuncture did not have any convincing effect on HRV in healthy subjects. More published work is needed in this area to determine if HRV can be an indicator of the therapeutic effect of acupuncture.

Differential postural control and sensory organization in young tennis players and taekwondo practitioners.

This study compared the sensory organization and standing balance of adolescent tennis players, taekwondo (TKD) practitioners, and healthy control participants. Sixty participants including 12 tennis players, 21 TKD practitioners, and 27 healthy control participants were tested. All of the participants underwent the Sensory Organization Test (SOT) and the Unilateral Stance Test (UST) on a Smart Equitest system. Results revealed that tennis players had higher SOT visual ratios than the control participants (p = .005), and TKD practitioners swayed more slowly in the UST than the control participants (p = .039). No differences (p > .05) were found in the composite score, somatosensory ratio, or vestibular ratio between the groups. Tennis players swayed less when they relied more on visual input to maintain balance, whereas TKD practitioners were more stable when standing on one leg. Parents may consider these sports as recreational activities for their children to develop specific balance abilities.

Effects of qigong exercise on upper limb lymphedema and blood flow in survivors of breast cancer: a pilot study.

HYPOTHESIS: Qigong exercise is a popular method for relieving the side effects of conventional cancer treatments in survivors of breast cancer, yet its effects are not empirically assessed. This study aimed to investigate the effects of qigong exercise on upper limb lymphedema, arterial resistance, and blood flow velocity in survivors with breast cancer and mastectomy. STUDY DESIGN: This study was conducted as a prospective clinical trial. METHODS: Eleven survivors of breast cancer with qigong experience (mean age = 58.3 ± 10.1 years) were assigned to the experimental group and 12 survivors of breast cancer without qigong experience (mean age = 53.8 ± 4.2 years) were assigned to the control group. They all had breast cancer-related lymphedema. All procedures were completed within one session. After baseline measurements were taken, the experimental group performed 18 Forms Tai Chi Internal Qigong for approximately 6 minutes while the control group rested for similar duration in a sitting position. Both groups were then reassessed. All participants were measured on their affected upper limb circumference (by using tape measures), peripheral arterial resistance, and blood flow velocities (using a Doppler ultrasound machine). RESULTS: The between-group differences were not significant for all outcome measures at baseline (P > .05). The circumferences of the affected upper arm, elbow, forearm and wrist decreased after qigong exercise (P < .05). However, no significant difference was found in the circumference measures between the 2 groups posttest (P > .0125). In terms of vascular outcomes, the resistance index decreased and the maximum systolic arterial blood flow velocity (SV) and minimum diastolic arterial blood flow velocity (DV) increased significantly after qigong exercise (P < .05). The between-group difference was close to significant for SV (P = .018) and was significant for DV (P < .001) posttest. CONCLUSION: Qigong exercise could reduce conventional cancer therapy side effects such as upper limb lymphedema and poor circulatory status in survivors of breast cancer. However, such effects may be temporary, and further studies must be conducted to explore longer term effects.

Shoulder Mobility, Muscular Strength, and Quality of Life in Breast Cancer Survivors with and without Tai Chi Qigong Training.

Objectives. To compare the shoulder mobility, muscular strength, and quality of life (QOL) among breast cancer survivors with and without Tai Chi (TC) Qigong training to those of healthy individuals and to explore the associations between shoulder impairments and QOL in breast cancer survivors with regular TC Qigong training. Methods. Eleven breast cancer survivors with regular TC Qigong training, 12 sedentary breast cancer survivors, and 16 healthy participants completed the study. Shoulder mobility and rotator muscle strength were assessed by goniometry and isokinetic dynamometer, respectively. QOL was assessed using the Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. Results. Goniometric measurements of the active range of motion in the flexion, abduction, and hand-behind-the-back directions were similar among the three groups. The TC Qigong-trained breast cancer survivors had significantly higher isokinetic peak torques of the shoulder rotator muscles (at 180°/s) than untrained survivors, and their isokinetic shoulder muscular strength reached the level of healthy individuals. Greater shoulder muscular strength was significantly associated with better functional wellbeing in breast cancer survivors with TC Qigong training. However, no significant between-group difference was found in FACT-B total scores. Conclusions. TC Qigong training might improve shoulder muscular strength and functional wellbeing in breast cancer survivors.

Differential effect of Taekwondo training on knee muscle strength and reactive and static balance control in children with developmental coordination disorder: a randomized controlled trial.

This randomized controlled trial aimed to investigate the effect of short-term intensive TKD training on the isokinetic knee muscle strength and reactive and static balance control of children with developmental coordination disorder (DCD). Among the 44 children with DCD (mean age: 7.6 ± 1.3 years) recruited, 21 were randomly assigned to undergo daily TKD training for 1h over three consecutive months, with the remaining 23 children being assigned to the DCD control group. Eighteen typically developing children (mean age: 7.2 ± 1.0 years) received no training as normal controls. Knee extensor and flexor muscle strength and reactive and static balance control were assessed using an isokinetic machine (with low, moderate and high movement velocities), a motor control test (MCT) and a unilateral stance test (UST), respectively. A repeated measures MANCOVA revealed a significant group through time interaction effect in isokinetic outcomes at 180°/s and in the UST outcome. Post hoc analysis demonstrated that DCD-TKD children's isokinetic knee muscle strength, specifically at 180°/s, was as high as that of the normal control children (p>0.0083) after TKD training. Moreover, UST body sway velocity was slower in the DCD-TKD group than in the DCD control group (p<0.001), and was comparable to that of the normal control group (p>0.05) after TKD training. However, no such improvement in balance was observed in the MCT (p>0.025). The results show that children with DCD who undergo a 3-month program of intensive TKD training experience improvements in isokinetic knee muscle strength at 180°/s and static single-leg standing balance control, but do not benefit from improved reactive balance control.

Digitalizing traditional chinese medicine pulse diagnosis with artificial neural network.

OBJECTIVES: The increasing popularities of traditional Chinese medicine (TCM) and telehealth indicate a need for digitalizing major clinical assessment methods used during TCM consultations. In this study, an electronic TCM pulse diagnostic system was developed, and its validity was explored. MATERIALS AND METHODS: The system was developed with an artificial neural network (ANN). The output neurons were TCM pulse qualities operationalized as the intensity of eight elements (depth, rate, regularity, width, length, smoothness, stiffness, and strength) at six locations (left and right cun, guan, and chi). The input neurons were physical parameters of arterial pressure waveform acquired from the six locations by a pulse acquisition device. TCM pulse quality was rated by a TCM doctor on a 0-10 visual analog scale. Physical parameters were extracted from the arterial pressure waveform with a pulse extraction program developed in-house. The model structure, including number of hidden neurons and hidden layers, and training algorithms were manipulated to optimize model performance. The value of r² was the outcome measure indicating model performance. RESULTS: Two hundred twenty-nine subjects were recruited. Four-layer ANN models trained with 45 hidden neurons and the Levenberg-Marquardt algorithm performed the best. The r² ranged from 0.60 to 0.86. CONCLUSIONS: The validity of the proposed system generated by ANN is established and can assist TCM doctors in collecting relevant health data during telehealth consultation.

Effect of acupressure in treating urodynamic stress incontinence: a randomized controlled trial.

The efficacy of acupressure therapy in managing urodynamic stress incontinence has not been fully investigated. This study evaluates the effects of a validated acupressure protocol for treating women with urodynamic stress incontinence. A randomized, single-blinded, placebo-controlled trial with a before-and-after study design was conducted. Eighty-one women aged between 18 and 60 were recruited at a urogynecology clinic in an acute hospital in Hong Kong. Participants were randomly assigned to an intervention (acupressure) group, a sham group, or a usual care (control) group. A validated acupressure protocol was employed in the intervention group. The intervention comprised three weekly sessions of 30 minutes each for a total of thirty sessions. Outcome measures included pelvic floor muscle strength, number of episodes of urine leakage over four days, self-reported severity of urine leakage, and responses on the Chinese version of the King's Health Questionnaire. No adverse effects were reported. Five percent of the participants dropped out of the study. Intention-to-treat analysis was conducted, the results indicated significant differences in pelvic floor muscle strength across the three groups (H =7.05, p =0.03) and in self-reported severity of urine leakage between the intervention and control groups (Z = -2.48, p = 0.01). Significant improvement in all domains of the Chinese version of the King's Health Questionnaire was evident in the intervention group. Acupressure is a simple and non-invasive intervention that appears to have positive physiological and psychological effects on women with urodynamic stress incontinence. The findings support acupressure as an intervention option for managing urodynamic stress incontinence in women.

Garment needs of pregnant women based on content analysis of in-depth interviews.

AIMS: This study aims to identify the needs, concerns and problems of pregnant women when using maternity support garments. BACKGROUND: Maternity support belt is regarded as helpful in reducing low back pain during pregnancy. However, several garment-related problems exist which might lead to poor adherence behaviour undermining the benefit of garment therapy. DESIGN: A qualitative exploratory study. METHODS. Semi-structured interviews were conducted with 10 pregnant Chinese women who experienced low back pain during pregnancy. All the interviews followed an interview guide and different maternity support garments were shown to the participants as a method of tangible objects to stimulate responses. Content analysis was used to analyse the data. RESULTS: The results showed that 60% of pregnant women discontinued using maternity support garments due to excessive heat, perceived ineffectiveness, itchiness, excessive pressure around the abdomen and inconvenience of adjustment. The content analysis generated five main themes of needs including effective function, safety, skin comfort, ease to put on and take off and aesthetics of maternity support garments. DISCUSSION: The findings of the five main themes of needs were largely consistent with previous studies examining medical garments for overall satisfaction and compliance. The results revealed that women's physiological and psychological changes during pregnancy influenced their clothing preferences on both functional and aesthetical values. CONCLUSIONS: Maternity support garments are convenient and easily-accessible therapy to manage LBP during pregnancy and are frequently recommended and worn by pregnant women. However, inappropriate choice of garment therapy not only led to ineffectiveness but also undesirable effects. The key findings of the five main themes of garment needs in pregnant women will facilitate healthcare professionals in providing evidence-based advice to assist patients in the selection of an appropriate and optimal maternity support garment. RELEVANCE TO CLINICAL PRACTICE: These recommendations in the clinical practice will assist patients in making well informed treatment decisions and ultimately improve the quality of care.

Evaluation of services of the integrative health clinic in Hong Kong.

AIMS: (i) To provide a profile of the clients who have used the Integrative Health Clinic's services, (ii) to determine the clients' extent of satisfaction with the services received and (iii) to assess whether integrative therapies can/should be recommended to other clinics. BACKGROUND: Based on the integration of various health paradigms and the use of health promotion strategies, our Integrative Health Clinic in Hong Kong provides a range of different therapies for integrated symptom management. The integrative therapies are derived from conventional, complementary and alternative medicine. Design. Postal survey, followed by routine data analysis. METHOD: Hong Kong Chinese clients attending a residential community health clinic were surveyed about health status and satisfaction towards the services received. RESULTS: A total of 489 clients (30.8% were male and 69.2% female) were registered with the clinic during the study period. The mean age (SD) was 47.8 (15.4) years. The customer satisfaction survey found that traditional Chinese medicine consultation was the most frequently used modality of the Integrative Health Clinic, followed by pain management. Out of the 489 clients, those who attended the Integrative Health Clinic only once in the study period for an annual health assessment and those who died during the period were excluded from the survey, giving a total of 276 eligible clients. Out of the 276 clients, 52.5% (128) responded to the survey that asked them to evaluate their satisfaction with the services received at the clinic and the performance of the clinic's practitioners who interacted with them. For practitioner performance, the percentage of respondents who gave a rating of satisfaction was found to range between 86.3-64.3%, while the percentage of respondents who gave a rating of dissatisfaction ranged from 13.7-35.7%. Overall, the survey found that most aspects of the Integrative Health Clinic's services were rated as satisfactory. CONCLUSION: The overwhelming satisfaction of clients with the services they received at the Integrative Health Clinic suggests that this integrative health services model could be considered for adoption in other clinics in Hong Kong and perhaps the region. RELEVANCE TO CLINICAL PRACTICE: It is necessary to review the use of integrative therapies so as to provide more data for the evaluation of this increasingly popular modality of health services.

Prevalence of pain in a community population.

AIMS: To measure the prevalence of pain in a community-dwelling population, to gauge the impact of pain on their daily activities, and to describe the measures they used for pain management. METHODS: This was a cross-sectional survey using a standardized structured questionnaire. Subjects were recruited by random digit dialing sampling with the computer-assisted telephone interviewing system (CATI). Subjects were all residents of Hong Kong at the time of their telephone interviews. Questions were asked about the respondent's sex, age, educational level, occupation, pain location and duration, pain relief methods, and the impact of pain on daily life activities. The responses were automatically recorded by the system. RESULTS: A total of 2,126 respondents were successfully recruited and completed the questionnaire. The response rate was 37.1%. The prevalence of pain was 45.9%. The most common site of pain was the back. Impacts on daily lives were mainly those of mood, mobility, and work performance. Seeking medical advice was the most common relief measure taken to alleviate pain. Both Traditional Chinese medicine and alternative methods were popular. CONCLUSION: This study provides an estimate of the prevalence of pain in the Chinese community in Hong Kong. Western medicine as well as Chinese and alternative methods is popular.

Auriculotherapy on low back pain in the elderly.

The objective of the study was to examine the effectiveness of auriculotherapy using magnetic pellets for the elderly suffering from low back pain (LBP). Sixty participants who were 60-years old or above and had been suffering from LBP were recruited. Participants were randomly allocated to receive auriculotherapy on a 3-week basis using either Semen Vaccariae (control group=30) or magnetic pellets (experimental group=30). Seven auricular acupoints that are believed to have an effect on LBP were selected. Treatment effects were evaluated using the Chinese Pain Intensity Verbal Rating scale (VRS). The experimental group had indeed experienced a significant improvement in pain relief when compared with the control group; and the therapeutic effects were sustained at 2 and 4-week follow-up periods after the therapy. Findings of this study demonstrated that auriculotherapy using magnetic pellets significantly reduce the pain intensity level of the elderly suffering from non-specific LBP.
