Objectives: to assess the frequency of late motor development in premature children admitted to a neonatal unit and to identify associated factors. Methods: a descriptive analytical study carried out at the Neonatal Unit of a high-risk maternity hospital in Recife, Brazil. Motor development was assessed using the Test of Infant Motor Performance, in 98 preterm children with a minimal post-conception age of 34 weeks, during admission to hospital, between January and June 2009. Associations were examined between variables relating to the mother, the newborn, the care provided and motor development. Results: the mean post-conception age on evaluation was 37 weeks and 39.8% of the children had some kind of impaired motor development (atypical or suspected to be atypical). Factors significantly associated with changes in motor development were: lower birth weight; higher age on evaluation; greater number of prenatal sessions; occurrence of hypoxia and bronco-pulmonary dysplasia; longer stay in ICU and neonatal unit. There was a significant trend for motor development to worsen with prolonged use of oxygen-therapy and mechanical ventilation. Conclusions: premature children admitted to hospital may show early signs of delayed motor development of a severe or borderline nature. Birth weight, neonatal morbidities and care received at the neonatal unit were the factors that most strongly influenced the outcome. These results justify initiation of preventive strategies and stimulation while the child is still in hospital.

This study analyzed the 'pressing with one finger' technique for wrist pulse-taking and explored the identification of internal organs according to the resonance theory in the circulatory system. A five-section discretized- transmission-line model of the distal upper limb was proposed considering the radial artery, the distal positions chi-guan-cun, and the hand vasculature. The transfer function of the model was parameterized in terms of its resonance frequency and respective amplification factor. Rheological and geometrical parameters of the modeled arterial system were used to simulate a sample of 1000 healthy volunteers subjected to wrist pulse-taking examination. The 'pressing with one finger' technique was simulated individually at each position by varying the vertical (minor) diameter of the elliptical cross-sectional radial artery from 0% to 99%. The pulse waveform harmonics were calculated in the frequency domain and had their internal organs assigned according to the resonance theory. Compressions in range 0-70% resulted in resonance frequencies around 3-6 Hz (related to the spleen) and amplification factors > 1. Compression in range 70-85% shifted up the resonance frequency of the majority of cases up to 6-8 Hz (related to the heart) and a minority of cases was shifted down to 0-2 Hz. A large decrease in the amplification factor occurred with module values <1. Compressions in range 85-99% increased the resonance frequency to 7-10 Hz (related to the gallbladder) with an even decent amplification factor. These effects were more pronounced in the proximal to distal sequence of positions. Therefore, pressing with one finger amplified specific pulse wave harmonics as a function of depth in all three positions, but it did not explore all harmonics described by the resonance theory. © 2012 Elsevier Ltd.

Between-set rest intervals (RIs) may influence accumulated fatigue, work volume, and therefore oxygen uptake (VO2) and energy expenditure (EE) during resistance training. The study investigated the effects of different RIs on VO2 and EE in resistance exercises performed with multiple sets and recruiting large and small-muscle mass. Ten healthy men performed 4 randomized protocols (5 sets of 10 repetitions with 15 repetition maximum workloads in either horizontal leg press [LP] or chest fly [CF] with an RI of 1 and 3 minutes). The VO2 was measured at rest, within sets, and during 90-minute postexercise recovery (excess postexercise oxygen consumption [EPOC]). The EE was estimated from VO2net (total VO2 2 rest VO2). The -V O2 increased in all protocols, being higher within the exercises and during EPOC in the LP than in the CF regardless of the RI. The 1-minute RI induced higher accumulated VO2 during LP (p < 0.05) but not during CF. The EPOC lasted approximately 40 minutes after LP1, LP3, and CF1, being longer than after CF3 (20 minutes, p < 0.05). Total EE was mainly influenced by muscle mass (p < 0.001) (LP3 = 91.1 6 13.5 kcal ; LP1 = 88.7 6 18.4 kcal . CF1 = 50.3 6 14.4 kcal ; CF3 = 54.1 6 12.0 kcal). In conclusion, total VO2 was always higher in LP than in CF. Shortening RI enhanced the accumulated fatigue throughout sets only in LP and increased VO2 in the initial few minutes of EPOC, whereas it did not influence total VO2 and EE in both exercises. Therefore, (a) the role of RI in preventing early fatigue seems to be more important when large-muscle groups are recruited; (b) resistance exercises recruiting large-muscle mass induce higher EE because of a greater EPOC magnitude. © 2011 National Strength and Conditioning Association.

Chinese medicine is among other traditional medical systems practiced either as a coadjutant intervention to Greek medicine or as the unique therapeutic intervention for illness prevention, treatment or rehabilitation. The complete spectrum from that traditional system includes acupuncture and moxibustion, herbal and food therapy, massage therapy (tuina), physical exercises (taijiquan), and breathing exercises (qigong). In this article, it is presented several randomized controlled trials and systematic reviews on the application of all therapeutic modalities from Chinese medicine in the physical rehabilitation scenario. The discussed studies encompasses both "positive" and "negative" results of Chinese medicine intervention for disabilities due to illnesses of the nervous, musculoskeletal or cardiovascular systems. Additionally, the importance of the personalized approach for Chinese medicine and rehabilitation is emphasized together with the need for reproducible methods for pattern differentiation and intervention selection. Chinese medicine resources are recognized as promising methods for therapeutic rehabilitation and can be incorporated into the rehabilitation science. The wide variety of therapeutic resources explains why Chinese medicine is currently a multidisciplinary practice for health protection and promotion, early diagnosis and treatment as well as rehabilitation with roles in the public health care system. © 2013 Chinese Association of the Integration of Traditional and Western Medicine and Springer-Verlag Berlin Heidelberg.

Farinatti, PTV, da Silva, NSL, and Monteiro, WD. Influence of exercise order on the number of repetitions, oxygen uptake, and rate of perceived exertion during strength training in younger and older women. J Strength Cond Res 27(3): 776-785, 2013-The study investigated the effect of resistance exercise order on the number of repetitions, oxygen uptake (V̇O 2max) and rate perceived exertion (RPE) in younger (YG: N = 10; 22 6 2 years; V̇O2peak 42.2 6 2.9 ml·kg -1·min-1) and older (EG: N = 8; 69 6 7 years; V̇O2peak 22.7 6 2.5 ml·kg-1·min -1) women. The subjects performed 3 sets of each exercise until fatigue using 10 repetition maximum in 2 sequences of opposite order: (a) sequence A (SEQA): bench press (BP), machine shoulder press (SP), pulley triceps extension (TE); (b) sequence B (SEQB): TE-SP-BP. The V̇O2 was assessed during the exercises, rest intervals, and 20 minutes after sequences (postexercise oxygen consumption [EPOC]). The number of repetitions decreased in both groups (p < 0.05) throughout sets. No difference (p > 0.22) was found between sequences for total V̇O2 (exercise sequences + EPOC) in YG (SEQA = 25.41 6 6.51 L vs. SEQB = 24.81 6 4.08 L) and EG (SEQA = 26.45 6 5.24 L vs. SEQB = 26.91 6 4.62 L). In both groups, the V̇O 2 within the sequences was higher during BP when it was placed at the end of SEQB, the same occurring with TE in SEQA (p , 0.05). The V̇O 2 within sequences and RPE were higher in SEQB compared with SEQA (p , 0.05) in EG but not in YG. In conclusion, the exercise order did not affect total V̇O2. The V̇O2 within a given sequence was always lower when an exercise was performed first as compared with last regardless of the exercise order. Accumulated fatigue reflected by the V̇O2 within sequences and RPE was influenced by the exercise order only in EG, suggesting that to prevent early fatigue, resistance training sessions in this group should preferably progress from large toward small-muscle group exercises. © 2013 National Strength and Conditioning Association.

Exercise intensity is an important aspect of enhancing health-related fitness. Relationships between the percentages of heart rate reserve (%HRR), maximal oxygen uptake (%VO2max) and oxygen uptake reserve (%VO2R) have been proposed as being effective for exercise intensity prescription. The present paper reviewed experimental studies published between 1966 and 2010, which investigated the relationships between the %HRR, %VO2max and %VO2R. The following aspects were focused upon: (a) comparisons of the relationships between %HRR, %VO2max and %VO2R at different exercise intensities; (b) methodological differences in determining resting VO2 and VO2max and associated effects on the above relationships; (c) applicability of the %HRR-%VO2max and %HRR-%VO2R relationships for exercise prescription. Fifteen studies published between 1997 and 2010 met inclusion criteria. Five studies observed the %HRR-%VO2R relationship, while the others also investigated the %HRR-%VO2max relationship. Six studies found that the %HRR was closer to the %VO2R than the %VO2max. Most studies did not satisfy the recommended methodological criteria for assessing the resting VO2, or used incremental test protocols which may have underestimated VO2max. None investigated the stability of the %HRR-%VO2R relationship in training conditions, such as during prolonged submaximal exercise. In conclusion, many of the reviewed studies presented methodological limitations that compromised their results in relation to the application of the %HRR-%VO2R relationship for prescribing aerobic training. © 2010 Sports Medicine Australia.

Background: Whether pattern similarity causes misdiagnosis and undiagnosis in Chinese medicine is unknown. This study aims to test the effect of pattern similarity and examination methods on diagnostic outcomes of pattern differentiation algorithm (PDA).Methods: A dataset with 73 Zangfu single patterns was used with manifestations according to the Four Examinations, namely inspection (Ip), auscultation and olfaction (AO), inquiry (Iq) and palpation (P). PDA was applied to 100 true positive and 100 true negative manifestation profiles per pattern in simulation. Four runs of simulations were used according to the Four Examinations: Ip, Ip+AO, Ip+AO+Iq and Ip+AO+Iq+P. Three pattern differentiation outcomes were separated, namely correct diagnosis, misdiagnosis and undiagnosis. Outcomes frequencies, dual pattern similarity and pattern-dataset similarity were calculated.Results: Dual pattern similarity was associated with Four Examinations (gamma = -0.646, P < 0.01). Combination of Four Examinations was associated (gamma = -0.618, P < 0.01) with decreasing frequencies of pattern differentiation errors, being less influenced by pattern-dataset similarity (Ip: gamma = 0.684; Ip+AO: gamma = 0.660; Ip+AO+Iq: gamma = 0.398; Ip+AO+Iq+P: gamma = 0.286, P < 0.01 for all combinations).Conclusion: Applied in an incremental manner, Four Examinations progressively reduce the association between pattern similarity and pattern differentiation outcome and are recommended to avoid misdiagnosis and undiagnosis due to similarity. © 2011 Sá Ferreira; licensee BioMed Central Ltd.

BACKGROUND: Stroke is a morbid entity in Chinese medicine recognized for over 2 000 years with sensory-motor impairments reported by several classical authors. However, the majority of controlled clinical trials of acupuncture in the treatment of poststroke recovery failed to obtain significant long-term results on functional recovery. Moreover, contradictory results have been obtained regarding the immediate effects of acupuncture stimulation on the electrical activity of human skeletal muscles as observed using surface electromyography. These results raise the question of whether acupuncture has any effect on the neuromuscular level. This study aims to evaluate the immediate effects of manual acupoint stimulation on the electrical activity and strength of the biceps brachii of healthy individuals and patients with chronic hypertonic hemiparesis. METHODS AND DESIGN: The study proposes a single-blinded randomized clinical trial with four parallel groups. Healthy subjects and poststroke patients with chronic spastic hemiparesis will be submitted to a single acupuncture intervention puncturing either Quchi (Llll) or Tianquan (PC2). The immediate effects on muscle function will be assessed by surface electromyography and isometric force of the biceps brachii muscle as the primary outcome. Secondary outcomes comprise the frequency of patterns in each group, as well as the frequency distribution of manifestations. DISCUSSION: The proposed study design includes some improvements on common methodological issues on clinical trials with an integrative design. This study design is expected to provide new insights on the neuromuscular effects of acupuncture stimulation in healthy subjects and poststroke patients.

Frailty is a physiological vulnerability status of the patient which is associated with the increased number of hospitalization and death. To evaluate the prevalence of frailty and its associated factors in patients with chronic kidney disease (CKD) on conservative treatment (CT), hemodialysis (HD) and peritoneal dialysis (PD). Frailty was assessed in 146 patients (86 CT, 37 HD and 23 PD) and characterized as muscle weakness and exhaustion--by the physical aspect and vitality domains, respectively, evaluated in the SF-36 quality of life instrument; physical inactivity--if he or she answered "never" or "hardly ever" when asked about physical activity; and as unintentional weight loss (> 4.5 kg per year). Patients were divided into three groups: non-fragile (NF), pre-fragile (PF) and fragile (F). The demographic, clinical and laboratory data were extracted from patient charts. Frailty was diagnosed in 36% of patients on CT, 37.8% in HD and 47.8% in PD. It was characterized in 36.8% of patients aged between 20 and 40 years and 40.3% of those between 41 and 60 years. Frailty was significantly associated with the use of vitamin D (r = 0.16; p = 0.03), hemoglobin (r = -0.14; p = - 0.02) and intact parathyroid hormone (r = 0.16; p = 0.03). Frailty is common among patients with CKD on conservative treatment and dialysis, even in those who are not elderly. In the patients studied, the phenotype of frailty was associated with no usage of vitamin D, lower serum levels of hemoglobin and higher levels of parathyroid hormone.

Between-set rest intervals (RI) may be determined using exercise-recovery-ratio (ERR) or fixed periods. The study investigated the influence of different ERR and fixed RI on the training volume in sessions aiming for hypertrophy with upper-body exercises recruiting different muscle mass (bench press-BP and triceps extension-TE). Sixteen men (25±2 years, 78±6 kg, 178±5 cm) with previous experience in resistance training performed 5 sets of maximum repetitions in each exercise with five RI protocols (RR1:3 [I3]; ERR1:5 [I5]; ERR1:7 [I7]; increasing ERR [IP] (1:3-1:5-1:7-1:9); 2-min fixed [2F]) in a counterbalanced design. The number of repetitions and work volume (load x repetitions) in each set and along the sessions (load x repetitions x sets) were compared across the RI protocols. The maximum repetitions decreased along with the sets in both exercises, but TE had lower percent decrease compared to BP, due to a longer time to perform the sets and therefore longer absolute rest time (P<0.05). The I3 exhibited the lowest repetitions sustainability (P<0.05). The training volume in I7, IP and 2F was always higher than I3 and I5 (P>0.05). However the absolute RI in 2F (~2 min) was shorter than in I7 and IP (~3 min), which reduced the total duration of the training session. Determining between-set RI based on ERR instead of using fixed intervals does not enable more work to be done in multiple-set/high intensity resistance training sessions.
