Subjective sleep quality and association with depression syndrome, chronic diseases and health-related physical fitness in the middle-aged and elderly.

BACKGROUND: As a complex phenomenon, sleep quality is difficult to objectively define and measure, and multiple factors related to sleep quality, such as age, lifestyle, physical activity, and physical fitness, feature prominently in older adult populations. The aim of the present study was to evaluate subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and to associate sleep quality with health-related physical fitness factors, depressive symptoms, and the number of chronic diseases in the middle-aged and elderly. METHODS: We enrolled a total of 283 middle-aged and elderly participants from a rehabilitation clinic or health examination department. The PSQI was used to evaluate sleep quality. The health-related fitness assessment included anthropometric and physical fitness parameters. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CES-D) short form. Data were analyzed with SPSS 18.0, and descriptive statistics and logistic regression analysis were used for the analyses. RESULTS: Overall, 27.9% of participants in this study demonstrated bad sleepers (with a PSQI score of > 5), 10.2% of study participants frequently used sleep medication to help them fall asleep, and 6.0% reported having significant depressive symptoms (with a CES-D score of ≥10). There are two major findings: (1) depression symptoms, the number of chronic diseases, self-rated health, and arthritis were significantly associated with a poor sleep quality, and (2) the 2-min step test was associated with longer sleep latency. These results confirmed that the 2-min step was associated with a longer sleep latency among the health-related physical fitness items. CONCLUSIONS: Our study found that depressive syndrome, chronic disease numbers, a poor self-rated health status, and arthritis were the main risk factors that influenced subjective sleep quality.

Effects of a dynamic combined training on impulse response for middle-aged and elderly patients with osteoporosis and knee osteoarthritis: a randomized control trial.

Dynamic combined training is a crucial component in treating musculoskeletal conditions to increase muscle strength and improve functional ability. This randomized control trial aimed to examine the effect of dynamic combined training on muscle strength and contractile rate of force development (RFD) in patients with osteoporosis (OP) and knee osteoarthritis (KOA). 58 participants with OP or KOA were randomly assigned to a control group (CG) (CGOP, n = 12; CGKOA, n = 15) or training group (TG) (TGOP, n = 14; TGKOA, n = 17). The training group participated in a 12-week, three-days-per-week supervised program consisting of stretching and warm-up exercises (10 min), hydraulic resistance training (40 min), and cool-down and relaxation exercises (10 min). All participants were evaluated at baseline and post-training. The maximal voluntary contraction (MVC) and contractile RFD at 0-200 ms increased significantly in middle-aged and older patients with OP. As for KOA, the dynamic combined training program was effective in improving the muscle strength. The maximal voluntary contraction (MVC) and contractile RFD at 0-200 ms increased significantly (by 29.22%, P = .000 and 27.25%, P = .019, respectively) in middle-aged and older patients with OP. In the KOA group, MVC and contractile RFD improved but did not reach statistical significance. The dynamic combined training program is effective for health promotion in older adults with OP or KOA.

Reconstruction of Single Image from Multiple Blurry Measured Images.

The problem of blind image recovery using multiple blurry images of the same scene is addressed in this paper. To perform blind deconvolution, which is also called blind image recovery, the blur kernel and image are represented by groups of sparse domains to exploit the local and nonlocal information such that a novel joint deblurring approach is conceived. In the proposed approach, the group sparse regularization on both the blur kernel and image is provided, where the sparse solution is promoted by -norm. In addition, the reweighted data fidelity is developed to further improve the recovery performance, where the weight is determined by the estimation error. Moreover, to reduce the undesirable noise effects in group sparse representation, distance measures are studied in the block matching process to find similar patches. In such a joint deblurring approach, a more sophisticated two-step interactive process is needed in which each step is solved by means of the well-known split Bregman iteration algorithm, which is generally used to efficiently solve the proposed joint deblurring problem. Finally, numerical studies, including synthetic and real images, demonstrate that the performance of this joint estimation algorithm is superior to the previous state-of-the-art algorithms in terms of both objective and subjective evaluation standards. The recovery results of real captured images using unmanned aerial vehicles are also provided to further validate the effectiveness of the proposed method.

Does functional fitness decline in accordance with our expectation? - a pilot study in healthy female.

BACKGROUND: Aging may cause various functional abilities gradually deteriorate. With changes in social forms, the trend of functional fitness decline will change accordingly. Therefore, this study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups. METHODS: Thirty six healthy females were divided into 3 age groups: young healthy females (20 to 30 y); middle-age (45 to 55 y); and older (65 to 75 y). Functional fitness test battery included flexibility, muscle strength/endurance, aerobic endurance, balance and agility. RESULTS: The performance in the elderly group was significantly worse (P < .05) in all the tests, whereas the muscle strength and endurance, as well as aerobic endurance for the middle-age group showed significantly lower than young groups (P < .05). CONCLUSIONS: The reduction in lower extremity muscle strength occurs in the middle-age group. We recommend that middle-age women be conscious of the reduction in their lower extremity muscle strength and conduct advanced preparations for future aging.

The therapeutic effect of collateral meridian therapy is comparable to acupoint pressure therapy in treating myofascial pain syndrome.

PURPOSE: This study compared the therapeutic effects of collateral meridian therapy (CMT) with traditional acupoint pressure therapy (APT) in patients with unilateral upper back pain. MATERIAL AND METHODS: Forty-nine patients with active myofascial trigger points in upper trapezius muscle were randomly allocated to the control (CTL), APT, or CMT group. Each subject in the CMT and APT groups received 2 sessions of treatment per week over 1 month. RESULTS: Patients in the APT and CMT groups showed significant improvements 1 month after treatment in visual analogue scale, range of motion, pain pressure threshold, regional superficial blood flow, and physical health, as compared to the CTL group. No significant differences in outcome measures were found between APT and CMT groups 1 month after treatment. CONCLUSION: Both APT and CMT have comparable therapeutic efficacy in the treatment of unilateral upper back pain with active myofascial trigger points in the upper trapezius muscle.

The discrimination of using the short physical performance battery to screen frailty for community-dwelling elderly people.

PURPOSE: This study explored the risk factors, cut-off points, sensitivity, specificity, positive predictive values, and negative predictive values of physical performance testing among community-dwelling frail elderly people in Taiwan. ORGANIZING CONSTRUCT: The empirical measurement of frailty is based on the following five indicators: weight loss, weakness, exhaustion, slow responses, and minimal physical activity. The frail phenotype is considered present if three or more of the indicators are observed. Meanwhile, a short battery of physical performance tests was conducted to assess the balance, mobility, and flexibility among elderly people. METHODS: A cross-sectional research design was executed. Participants were evaluated using a short battery of physical performance tests to assess their physical performance. Multivariate logistic regression and receiver operating characteristic (ROC) analyses were performed. FINDINGS: The logistic regression results showed that the factors significantly correlated to frailty included falls in the previous year, smoking, hypertension, and bone and joint disease. Physical performance test scores were analyzed using the ROC curves to discriminate frailty statuses. The analysis results showed that the areas under the ROC curves for the diagnostic accuracy of right-hand grip, left-hand grip, and the 8-foot up-and-go test reached 0.70, and the optimal cut-off points determined using Youden's index were 17.25 kg, 20.75 kg, and 8.13 s, respectively. CONCLUSIONS: The research findings suggest that physical performance variables can be used to effectively screen elderly people at risk for frailty in the community. CLINICAL RELEVANCE: The findings offer reference values for physical performance tests specific to community-dwelling frail elderly people. The information can enable health practitioners to achieve early identification of frailty among elderly people with anthropometric characteristics similar to those associated with people in Asian countries.

Minimally invasive knee arthroplasty with the subvastus approach allows rapid rehabilitation: a prospective, biomechanical and observational study.

[Purpose] To study the recovery of patients treated with minimally invasive total knee arthroplasty (TKA) performed via the subvastus approach, and to develop an optimal rehabilitation program for these patients. [Methods] Twenty-two patients (17 females and 5 males; mean age 69.2 years), who received unilateral minimally invasive TKA for osteoarthritis, underwent isometric and isokinetic muscle testing and completed a quality of life questionnaire, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), before and after surgery. Muscle strength and ultrasound tests were repeated 1, 2, 6, and 12 months after surgery. [Results] Strength and range of motion were initially lower in the operated knees but demonstrated no significant difference from the healthy knees after 12 months. Sonographically, joint effusion was greater in the osteoarthritic knees than in the healthy knees at baseline, but no significant difference was observed after 12 months. The mean WOMAC pain, stiffness and function scores all decreased from baseline to 6 months, and then slightly increased at 12 months, but only the function score showed a significant difference compared to baseline. [Conclusions] One year after minimally invasive TKA using a subvastus approach, patients had a good overall prognosis, with prompt functional recovery.

A healthcare edition of sporting equipment for middle-aged and elderly.

The aging phenomenon results in body organ system debilitating, which causes the balance weakening and makes a fall, fracture rate, and further medical cost to increase. The lack of exercise has been linked to increasing the incidence of hypertension, coronary artery disease, osteoporosis, degenerative arthritis, and diabetes. Chronic disease affects patients both in psychological and physiological functions which limit their daily activity. In the past, many researches pointed out that these patients can improve their balance sensation by exercise. Because of the above reasons, this research implementation forms a wireless platform of information connection system and medical data analysis. First of all, the target population in the society focuses on those elderly with the common chronic diseases, such as skeletal muscle diseases and degenerative arthritis. Using the hydraulic resist practicing equipment as the mainstay intervention can help examinee collecting the practice value and further analysis. The platform of information accords not only the data prior and after the exercise but also graphic data presentation and analysis from the medical staff members providing services in the society. It can also provide the medical unit to create data mold and a body health counselor when services in the society.

Novel approaches to the parametric cubic-spline interpolation.

The cubic-spline interpolation (CSI) scheme can be utilized to obtain a better quality reconstructed image. It is based on the least-squares method with cubic convolution interpolation (CCI) function. Within the parametric CSI scheme, it is difficult to determine the optimal parameter for various target images. In this paper, a novel method involving the concept of opportunity costs is proposed to identify the most suitable parameter for the CCI function needed in the CSI scheme. It is shown that such an optimal four-point CCI function in conjunction with the least-squares method can achieve a better performance with the same arithmetic operations in comparison with the existing CSI algorithm. In addition, experimental results show that the optimal six-point CSI scheme together with cross-zonal filter is superior in performance to the optimal four-point CSI scheme without increasing the computational complexity.

Achilles tendon tear following shock wave therapy for calcific tendinopathy of the Achilles tendon: a case report.

INTRODUCTION: Extracorporeal shock wave therapy (ESWT) is becoming a popular method for the treatment of musculoskeletal disorders. We herein report a case of Achilles tendon rupture possibly related to ESWT. CASE REPORT: A 49-year-old female was treated with a calcaneal osteotomy due to Haglund's disease on the right. However, she developed chronic calcific Achilles tendinopathy postoperatively, and during the following 2 year period after surgery she received various non-steroidal anti-inflammatory drugs and one injection of corticosteroids. She was subsequently treated with extracorporeal shock wave therapy (ESWT), but persistent pain, local swelling and redness over posterior right ankle were noted. Two months after ESWT she experienced an Achilles tendon tear and received Achilles tendon reconstruction. CONCLUSION: While ESWT is generally considered safe, physicians should be aware of potential major complications.

Effects of needle electrical intramuscular stimulation on shoulder and cervical myofascial pain syndrome and microcirculation.

BACKGROUND: To evaluate the effects of needle electrical intramuscular stimulation (NEIMS) on myofascial trigger points (MTrPs) and their epidermal blood flow. METHODS: Forty adult patients with active MTrPs in the upper trapezius or levator scapulae underwent 4 weekly NEIMS sessions. Visual analog scale (VAS) and pain pressure threshold (PPT), along with cervical and shoulder range of motion (ROM) were used as outcome measures. Microcirculatory changes were also evaluated by laser Doppler flowmetry of the epidermal area above these MTrPs. Data were collected before and after each treatment. Paired t tests were used to compare pre- and post-treatment data. Outcomes were presented as box plots displaying medians and 25th to 75th percentile values. RESULTS: VAS and PPT pain significantly improved immediately after each treatment; effects persisted till the end of the experiment. NEIMS treatment also had immediate and mid-term positive effects on cervical and shoulder ROM. There was an overall negative correlation between epidermal blood flow and VAS score before the first treatment. Regional blood flow significantly increased immediately but temporarily after each treatment. CONCLUSION: NEIMS did have positive effects on myofascial pain syndrome, but the data did not indicate that increased regional microcirculation was the possible therapeutic mechanism.
