Effects of Yoga on Psychological Health, Quality of Life, and Physical Health of Patients with Cancer: A Meta-Analysis

Yoga is one of the most widely used complementary and alternative medicine therapies to manage illness. This meta-analysis aimed to determine the effects of yoga on psychological health, quality of life, and physical health of patients with cancer. Studies were identified through a systematic search of seven electronic databases and were selected if they used a randomized controlled trial design to examine the effects of yoga in patients with cancer. The quality of each article was rated by two of the authors using the PEDro Scale. Ten articles were selected; their PEDro scores ranged from 4 to 7. The yoga groups compared to waitlist control groups or supportive therapy groups showed significantly greater improvements in psychological health: anxiety (P = .009), depression (P = .002), distress (P = .003), and stress (P = .006). However, due to the mixed and low to fair quality and small number of studies conducted, the findings are preliminary and limited and should be confirmed through higher-quality, randomized controlled trials.

Effects of exercise programmes on quality of life in osteoporotic and osteopenic postmenopausal women: a systematic review and meta-analysis:

Objective: To examine the effect of exercise therapy on quality of life in postmenopausal women with osteoporosis or osteopenia. Methods: We searched MEDLINE, CINAHL, PEDro, EMBASE and the Cochrane library from January 1966 to March 2007. Two reviewers independently selected all studies that met predetermined inclusion criteria. Randomized controlled trials that used the Short Form 36 of the Medical Outcome Study (SF-36) questionnaire or the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) as outcome measures were selected. The PEDro Scale was applied to rate the quality of each article. All studies had a quality score above 5/10. Meta-analysis was facilitated by RevMan 4.1. Results: Four randomized controlled trials met the inclusion criteria, involving a total of 256 participants. Results revealed that the exercise groups showed significant improvements in the domains of physical function, pain, role physical and vitality (P<0.05). Furthermore, intervention with combined exercise programmes had better effects on physical function, pain and vitality domains than controls. Group exercise programmes also produced better results in these three domains. A short-duration exercise programme produced more improvement in physical function, role physical and vitality, whereas a long-duration exercise programme resulted in more improvement in physical function and pain domains. Conclusions: This meta-analysis revealed better improvement in physical function, pain, role physical and vitality in the exercise groups. Combined exercise and group exercise programmes showed better outcomes in the physical function, pain and vitality domains, but different durations of exercise programme showed improvement in different domains.

Reliability study of measurements for lymphedema in breast cancer patients.

Chen Y-W, Tsai H-J, Hung H-C, Tsauo J-Y: Reliability study of measurements for lymphedema in breast cancer patients. Am J Phys Med Rehabil 2008;87:33–38. Objective:Water displacement, circumference measurement, and tissue tonometry are important methods to evaluate the status of lymphedemous limbs in breast cancer patients. The purpose of this study was to investigate the reliabilities, and define the limits for clinical change indicative of clinical improvement with respect to these three measures. Design:Fourteen patients were recruited for water displacement and circumference measurement, and 17 for tissue resistance by tonometry. All had been treated for breast cancer and subsequently developed lymphedema. Two physical therapists conducted the measurements to determine intra- and interrater reliability. Results:All measures had fair to excellent reliability (water displacement and circumference measurement, intraclass correlation coefficient [ICC] >0.99, P < 0.05; tissue tonometry, 0.66 < ICC < 0.88, P < 0.05). There was no systematic change in the mean for any of the measures. The variation, as determined by standard error of measurement (SEM), SEM%, smallest real difference (SRD), and SRD% was greatest for tissue tonometry. Conclusions:Water displacement and circumference measurement (but not tonometry) are reliable techniques for assessing lymphedema in clinical practice. The effect of modifying the tonometry protocol and increasing the amount of rater training should be studied to determine whether the reliability of this method can be improved.

A pilot randomized controlled trial to improve geriatric frailty

BackgroundFew randomized controlled trials (RCTs) report interventions targeting improvement of frailty status as an outcome.MethodsThis RCT enrolled 117 older adults (65-79 years of age) in Toufen, Taiwan who scored 3-6 on The Chinese Canadian Study of Health and Aging Clinical Frailty Scale Telephone Version and then score ≥1 on the Cardiovascular Health Study Phenotypic Classification of Frailty (CHS_PCF). With a two by two factorial design, subjects were randomly assigned to interventions (Exercise and nutrition, EN, n = 55 or problem solving therapy, PST, n = 57) or controls (non-EN, n = 62 or non-PST, n = 60). Educational booklets were provided to all. EN group subjects received nutrition consultation and a thrice-weekly exercise-training program while PST group subjects received 6 sessions in 3 month. Subjects were followed at 3, 6, and 12 months. Primary outcome was improvement of the CHS_PCF by at least one category (from pre-frail to robust, or from frail to pre-frail or robust) from baseline assessments. One hundred and one completed final assessments. Intention-to-treat analysis with the generalized estimating equation model was applied with adjustment for time and treatment-by-time interactions.ResultsMean age was 71.4 ± 3.7 years, with 59% females. Baseline characteristic were generally comparable between groups. EN group subjects had a higher improvement rate on the primary outcome than non-EN group subjects (45% vs 27%, adjusted p = 0.008) at 3 months, but not 6 or 12 months. They also had more increase of serum 25(OH) vitamin D level (4.9 ± 7.7 vs 1.2 ± 5.4, p = 0.006) and lower percentage of osteopenia (74% vs 89% p = 0.042) at 12 months. PST group subjects had better improvement (2.7 ± 6.1 vs 0.2 ± 6.7, p = 0.035, 6-month) and less deterioration (−3.5 ± 9.7 vs −7.1 ± 8.7, p = 0.036, 12-month) of dominant leg extension power than non-PST subjects. Some secondary outcomes were also improved in control groups (non-EN or non-PST). No adverse effects were reported.ConclusionsThe three-month EN intervention resulted in short-term (3-month) frailty status improvement and long-term effect on bone mineral density and serum vitamin D (12-month) among Taiwanese community-dwelling elders. The effect of PST was less pronounce.Trial registrationClinicalTrials.gov: EC0970301

Estimation of expected quality adjusted survival by cross-sectional survey.

To compare both mortality and quality of life (QOL) across different illnesses, we propose an estimator to calculate the expected quality adjusted survival (QAS) by multiplying the QOL into the survival function. While the survival function can be determined by the usual life table method, the QOL data can be collected by a cross-sectional survey among patients who are currently surviving. The area under the QAS curve is thus the expected utility of health of the specific illness, which may take a common unit of quality adjusted life year ready for outcome evaluation and policy decision. A simulation is performed to demonstrate that the proposed estimator and its standard error are relatively accurate. The limitations and guidelines for using this estimator are also discussed.

An alternative intervention for urinary incontinence: Retraining diaphragmatic, deep abdominal and pelvic floor muscle coordinated function

This study was a randomized controlled trial to investigate the effect of treating women with stress or mixed urinary incontinence (SUI or MUI) by diaphragmatic, deep abdominal and pelvic floor muscle (PFM) retraining. Seventy women were randomly allocated to the training (n = 35) or control group (n = 35). Women in the training group received 8 individual clinical visits and followed a specific exercise program. Women in the control group performed self-monitored PFM exercises at home. The primary outcome measure was self-reported improvement. Secondary outcome measures were 20-min pad test, 3-day voiding diary, maximal vaginal squeeze pressure, holding time and quality of life. After a 4-month intervention period, more participants in the training group reported that they were cured or improved (p < 0.01). The cure/improved rate was above 90%. Both amount of leakage and number of leaks were significantly lower in the training group (p < 0.05) but not in the control group. More aspects of quality of life improved significantly in the training group than in the control group. Maximal vaginal squeeze pressure, however, decreased slightly in both groups. Coordinated retraining diaphragmatic, deep abdominal and PFM function could improve symptoms and quality of life. It may be an alternative management for women with SUI or MUI.

Home-based trunk-strengthening exercise for osteoporotic and osteopenic postmenopausal women without fracture –a pilot study

Objectives: To investigate whether a 12-week home-based programme of trunk-strengthening exercise could benefit spinal mobility, function and quality of life for osteoporotic and osteopenic postmenopausal women without fracture. Designs: Randomized controlled clinical trial. Setting: Department of Physical Therapy in National Taiwan University Hospital. Subjects: Twenty-eight postmenopausal women (mean age 60.39=9.3 years) diagnosed with osteoporosis or osteopenia without fracture history were recruited for this study. Subjects were randomly assigned into exercise or control groups, each consisting of 14 subjects. Interventions: The 12-week exercise programme included strengthening routines for the trunk extensor and flexor muscles. The subjects performed three sets of 10 repetitions for each of the exercises, with programmes carried out three times per day at home. Main outcome measurements: Muscular strength, spinal range of motion (ROM) and motion velocity, Oswestry Disability Questionnaire (ODQ) and quality of life (QOL) were measured before the start and after completion of the exercise programme. Results: Statistically significant improvements were demonstrated in spinal ROM and motion velocity in the sagittal and frontal planes for the exercise group (pB=0.05). Further, the strength of the trunk flexors and extensors increased after exercise training (pB=0.05). ODQ measure was significantly reduced in the exercise group (pB=0.05), while the controls showed no significant change. Subjects in the exercise group showed better satisfaction in some domains of the Short-Form-36 Health Survey quality of life questionnaire (pB=0.05). Conclusions: This 12-week home-based trunk-strengthening exercise programme could improve trunk mobility and strength, and enhance QOL in osteoporotic and osteopenic postmenopausal women without vertebral fracture. Future study should recruit more cases or more severe subjects to verify the results.

Effects of a Multifactorial Fall Prevention Program on Fall Incidence and Physical Function in Community-Dwelling Older Adults With Risk of Falls

OBJECTIVE To evaluate effects of a multifactorial fall prevention program on fall incidence and physical function in community-dwelling older adults. DESIGN Multicenter randomized controlled trial. SETTING Three medical centers and adjacent community health centers. PARTICIPANTS Community-dwelling older adults (N=616) who have fallen in the previous year or are at risk of falling. INTERVENTIONS After baseline assessment, eligible subjects were randomly allocated into the intervention group (IG) or the control group (CG), stratified by the Physiological Profile Assessment (PPA) fall risk level. The IG received a 3-month multifactorial intervention program including 8 weeks of exercise training, health education, home hazards evaluation/modification, along with medication review and ophthalmology/other specialty consults. The CG received health education brochures, referrals, and recommendations without direct exercise intervention. MAIN OUTCOME MEASURES Primary outcome was fall incidence within 1 year. Secondary outcomes were PPA battery (overall fall risk index, vision, muscular strength, reaction time, balance, and proprioception), Timed Up & Go (TUG) test, Taiwan version of the International Physical Activity Questionnaire, EuroQol-5D, Geriatric Depression Scale (GDS), and the Falls Efficacy Scale-International at 3 months after randomization. RESULTS Participants were 76±7 years old and included low risk 25.6%, moderate risk 25.6%, and marked risk 48.7%. The cumulative 1-year fall incidence was 25.2% in the IG and 27.6% in the CG (hazard ratio=.90; 95% confidence interval, .66-1.23). The IG improved more favorably than the CG on overall PPA fall risk index, reaction time, postural sway with eyes open, TUG test, and GDS, especially for those with marked fall risk. CONCLUSIONS The multifactorial fall prevention program with exercise intervention improved functional performance at 3 months for community-dwelling older adults with risk of falls, but did not reduce falls at 1-year follow-up. Fall incidence might have been decreased simultaneously in both groups by heightened awareness engendered during assessments, education, referrals, and recommendations.

Comparison of the Effects of a Supervised Exercise Program and Usual Care in Patients With Colorectal Cancer Undergoing Chemotherapy

Background: Although exercise has been addressed as a promising therapy for cancer adverse effects, few studies have evaluated the beneficial effects of exercise for colorectal cancer (CRC) patients during chemotherapy. Objective: The purpose of this study was to compare the effects of supervised-exercise intervention with those of usual care on cardiorespiratory fitness, muscle strength, fatigue, emotional distress, sleep quality, and quality of life (QoL) in patients with CRC undergoing chemotherapy. Methods: Patients with stage II or III CRC admitted for adjuvant chemotherapy were allocated to either a supervised-exercise group that received a combined aerobic and resistance exercise program or a “usual care” control group for 12 weeks. The outcomes, QoL, muscle strength, cardiorespiratory fitness, emotional distress, physical activity, fatigue, and sleep quality, were assessed at baseline and after intervention. Results: Significant interactions between intervention and time were observed for the role functioning and pain subscales of QoL and physical activity level. The time main effects were significant for the secondary outcomes: hand-grip strength, cardiorespiratory fitness, physical activity level, and physical functioning, role functioning, social functioning, fatigue, and pain subscales of QoL. Conclusion: Compared with usual care, the supervised exercise demonstrated larger effects than usual care on physical activity level and role functioning and pain subscales of QoL. Implications for Practice: Supervised-exercise program is suggested to be incorporated as part of supportive care to promote the cardiorespiratory fitness, muscle strength, physical activity level, and QoL of patients with CRC undergoing chemotherapy.

Spinal Performance and Functional Impairment in Postmenopausal Women with Osteoporosis and Osteopenia without Vertebral Fracture

Abstract:Previous studies have paid much attention to the impact on functional impairment or quality of life from vertebral fractures secondary to osteoporosis, but little research has addressed the function of osteoporotic women without fractures. The purposes of this study were: (1) to describe spinal performance and functional impairment in postmenopausal women with osteoporosis and osteopenia without vertebral fracture, and (2) to investigate the relationship between them. Thirty postmenopausal women diagnosed as having osteoporosis or osteopenia were recruited who fulfilled the following criteria: (1) menopause for at least 6 months; (2) no vertebral fracture; (3) no medication that would interfere with calcium intake. Measurements included assessment of functional impairment and spinal performance including trunk extension/flexion isokinetic strength, spinal range of motion (ROM) and movement velocity in three planes (sagittal, frontal and transverse). The results showed that spinal ROM and velocity were significantly reduced in the osteoporosis group compared with the osteopenia group (p<0.05), but no significant difference in trunk strength was shown. Functional impairment level showed a slight difference between the two groups (p= 0.042). There was a significant correlation between spinal ROM and motion velocity with bone mineral density; however, functional impairment correlated with motion velocity only in the transverse plane (trunk rotation) (p<0.05). Spinal strength did not show any correlation with other parameters. It was concluded that spinal motion performance declined and functional impairment increased in relation to the severity of bone mineral loss in postmenopausal women without vertebral fracture, but their physical performance was not correlated with functional impairments.
