Faculty of Physical Therapy; Mahidol University. Faculty of Medicine Siriraj Hospital; Mahidol University. College of Sports Science and TechnologyTo determine the effects of a home-based walking program on lower extremity muscle strength of hemodialysis patients. [M ethods] Twenty-six hemo dialysis patients were divided into a training and a control group. Lower extremity muscle strength was meas ured using a back and leg dynamometer pr ior to and at the 4th, 8th, and 12th weeks of the study period in both groups. The trai ning group performed the home- based walking program, an individually prescribed walking progra m which progressively increased in duration by incrementing the number of steps by 10% every two weeks. Subjects in the control group were asked to keep to their routine activities, as much as possible, during the study period. [Results ] Lower extremity muscle strength in th e training group remarkably increased from 52 kg at baseline to 68 kg at the 12th week (4th week = 58 kg, 8th week = 63 kg), whereas no change in the control group was found (baseline = 51 kg, 4th week = 52 kg, 8th week = 51 kg, 12th week = 48 kg). [Conclusion] A home- based walking exercise program improved lower extremity muscle strength of hemo dialysis patients. Patients who have stable medical conditions should be enc ouraged to participate in this home-ba sed walking exercise program to improve their abilities to perform activities of daily livingPublication Metadata only Influence of Levodopa therapy on static balance in Parkinson’s disease(2014) Sirinthip Kamolsawat; Vimonwan Hiengkaew; Chanut Akamanon; Niphon Poungvarin; Mon S Bryant; Mahidol University. Faculty of Physical Therapy; Mahidol University. Faculty of Science. Department of Physiology; Mahidol University. Faculty of Medicine Siriraj HospitalObjective: To study the effect Levodopa on static standing balance in persons with Parkinson’s disease (PD). Methods: Twenty-seven persons with PD participated in the study. Persons with PD were tested for balance in a standing position using Sensory Organization Test (SOT) before (‘off’) and after taking the levodopa (‘on’) on the same day. SOT variables were average sway velocity, percentage of maximum stability and percentage of ankle strategy. Results: Levodopa significantly increased sway velocity under visual absence and visual distorted conditions (somatosensory, p < 0.05). Percentage of ankle strategy decreased after the medication when testing under eye open and eye close conditions (P < 0.05). No significant differences were found when compared the maximum stability the standing balance between ‘off’ and ‘on’ medications. Conclusion: Levodopa therapy improved the ability to maintain static balance under inappropriate somatosensory information and dependence on visual information with using hip strategy instead of ankle strategy but failed to influence the ability to maintain COG stability over the base of support in static standing. This study demonstrated that the different postural stability in PD. It could be fundamental data in helping clinicians to assess and plan an effective training regimen for PD.Publication Metadata only Metabolic equivalent of exercise stress test explained by six-minute walk test in post coronary artery bypass graft and post percutaneous coronary intervention patients(2014) Watesinee Khuangsirikul; Wattana Jalayondeja; Rungchai Chuanchaiyakul; Rungroj Krittayaphong; Chunhakasem Chotinaiwattarakul; Pansak Laksanabunsong; Mahidol University. Faculty of Physical Therapy; Mahidol University. College of Sports Science and Technology; Mahidol University. Faculty of Medicine Siriraj HospitalObjective: To investigate the relationship among metabolic equivalents of an exercise stress test (METs of EST), demographic parameters (age, body weight, height, BMI), peak oxygen consumption (VO2 peak), and six-minute walk distances (6MWD) determined from a six-minute walk test (6MWT). Material and Method: Exercise capacity was estimated by a 6MWT and EST at the sixth week post operation in post coronary artery bypass graft (post CABG, n = 17) and post percutaneous coronary intervention (post PCI, n = 13) patients. Results: METs of EST showed: high correlation (p < 0.01) with VO2 peak of 6MWT (r = 0.94), 6MWD (r = 0.92); muscle strength (r = 0.78), moderate correlation (p < 0.01) with height (r = 0.53); negative correlation with age (r = -0.50). Low correlation was found (p < 0.05) with step length (r = 0.43), and weight (r = 0.38). No correlation was found among METs of EST and rating perceived exertion (RPE) of EST and 6MWT. The multiple linear regression equation for explaining METs of EST is as follows: METs of EST = -2.94+0.02 (6MWD), (r = 0.923, R2 = 0.85, p < 0.001). Conclusion: The 6MWT may possibly be used as an alternative choice for estimating energy expenditure to design exercise programs for these post operation groups.Item Metadata only On the Development of Using the Non-Invasive Blood Oxygen Level Sensor for Quantifying Hemoglobin Concentration(2013) Khunawat Luangrat; Yunyong Punsawad; Prapat Suriyaphol; Yodchanan Wongsawat; Mahidol University. Faculty of Engineering. Department of Biomedical Engineering; Mahidol University. Faculty of Medicine Siriraj Hospital; Mahidol University. Center for Emerging and Neglected Infectious DiseasesIn this paper, we propose the non-invasive method for detecting hemoglobin concentration. Our hypothesis is that, for the patients who have high hemoglobin concentration, the average pulse amplitudes should be different from their normal condition. To verify our assumption, we diluted the blood of normal subjects by letting them drink the water. According to our experiment, 80% of the subjects had higher pulse amplitude.Publication Metadata only Respiratory muscle strength explained by age and weight in female and male(2014) Wattana Jalayondeja; Orawan Verner; Suwannee Jarungjitaree; Jamsak Tscheikuna; Mahidol University. Faculty of Physical Therapy; Mahidol University. Faculty of Graduate Studies; Mahidol University. Faculty of Medicine Siriraj HospitalObjective: To determine the relationship between respiratory muscle strength and age, sex, height and weight. Material and Method: Maximal inspiratory mouth pressure (MIP) and maximal expiratory mouth pressure (MEP) were assessed in 249 subjects aged 30-70 years using a mouth pressure meter. MIP was performed 10 times at residual volume, whereas MEP was performed 12 times at total lung capacity. Pearson’s correlation was used to assess the association between respiratory muscle strength and characteristics data. Multiple linear regressions were used to establish the prediction equation of respiratory muscle strength. Results: MIP decreased at ages beyond 60 years (p < 0.05) but age had no effect on MEP in both sexes. MIP was correlated with age, weight and height in males, and with age and weight only in females; whereas, MEP was not correlated with age, height and weight in either sex. Predicted MIP regression equations are MIPfemale = 77.57-0.59 age+0.62 weight (r2 = 0.164, p = 0.004), MIPmale = 124.39-0.91 age+0.63 weight (r2 = 0.175, p = 0.08). Conclusion: Sex, age and weight factors should be considered for MIP measurement.Publication Metadata only Responsiveness of pain, active range of motion, and disability in patients with acute nonspecific low back pain(2011) Prasert Sakulsriprasert; Roongtiwa Vachalathiti; Mantana Vongsirinavarat; Witchate Pichaisak; Mahidol University. Faculty of Physical Therapy; Mahidol University. Faculty of Medicine Siriraj HospitalAbstract Many parameters are now used for investigations in clinical settings, such as pain, active range of motion (AROM), and disability, but it is not yet known which parameters are responsive in patients with acute nonspecific low back pain (LBP). This study aimed to inves¬tigate the responsiveness of pain, AROM, and disability in patients with acute nonspecific LBP. Fifty subjects were assessed for pain, AROM, and disability at baseline and after 6 weeks. The effect size (ES) was calculated for each parameter. Also, patient's perception of change was collected after 6 weeks for correlating it with change scores for each parameter. The most responsive parameter for detecting the change in patients with acute nonspecific LBP was pain (ES, 1.57) and disability (ES, 0.93). However, AROM was proved to be less responsive. This study indicated that pain and disability were responsive in detecting the changes in patients with acute nonspecific LBP over time.Item Metadata only Ribonuclease zymogen designParit Plainkum; Mahidol University.

Faculty of Physical Therapy; Mahidol University. Faculty of Medicine Siriraj Hospital; Mahidol University. Institute of Nutrition; Mahidol University. Faculty of Science. Department of PhysiologyObjective: To compare lipid and carbohydrate use during and after a high-intensity endurance exercise bout between lean and obese subjects. Material and Method: Lean and obese healthy male subjects with energetic physical activity and stable body weight were recruited to participate in the present study. The respiratory exchange ratio (RER), lipid and carbohydrate oxidation, and lipid and carbohydrate energy expenditure during resting condition, high-intensity exercise and 180 min after exercise were determined by indirect calorimetry. Results: Ten lean and ten obese healthy male subjects, aged 26+4 years, completed a 300-kcal high-intensity exercise session. Resting energy expenditure and lipid energy expenditure in the obese group were significantly higher than those of the lean group. The RER, lipid oxidation, and carbohydrate oxidation were not significantly different between groups throughout the exercise period. The total energy expenditure and total lipid and carbohydrate energy expenditure were also not significantly different between lean and obese groups. During the 180-minute post exercise period, both lean and obese subjects showed a declination in RER and carbohydrate oxidation and an increase in lipid oxidation. Conclusion: Substrate use during and after high-intensity exercise between healthy lean and obese subjects was not significantly different. Both groups used carbohydrates and lipids as the main substrate sources during and after high-intensity exercise, respectively.Publication Open Access Three phase bone scintigraphy in evaluating revascularization and bone formation of natural biomaterial bone graft by using Tc99m MDP in rabbits(2015) Somkiat Huaijantug; Paranee Yatmark; Somsak Wattananit; Phingphol Charoonrut; Thonnapong Thongpraparn; Rujaporn Chanachai; Mahidol University. Faculty of Veterinary Science; Mahidol University. Faculty of Medicine Siriraj HospitalThree phase bone scintigraphy (TPBS) examined the viability of bone graft, revascularization, and bone formation using single photon emission computed tomography (SPECT) and the intravenous injection of 99M Technetium methylenediphosphonate (99MTc-MDP). Seven New Zealand White rabbits, aged 8 months had osteotomy of ulna performed, the left ulna substituted for natural biomaterial bone graft, containing gelatin sponge and hyaluronic acid, and the right ulna was replaced by vascularized autogenous bone graft. A post-operative scanning of bone using TPBS was done at 7 days and weekly, at week 1, 2, 4, 6, 8, 12 to evaluate revascularization and bone formation of natural biomaterial bone graft comparing with autogenous bone graft. The results demonstrated that the perfusion index and RCP of natural biomaterial bone graft and the autogenous bone graft in phases 1, 2, and 3 had no statistically significant difference when compared in between each week. The study also showed that, the ratio of the mean counts/pixel of the natural biomaterial bone graft in phase 3 had slightly lower than autogenous bone graft. This study provided model through which TPBS could evaluate revascularization and bone formation in this model. Natural biomaterial bone graft may be the same and as good a revascularization as autogenous bone graft although the bone formation of autogenous bone graft still has more efficiency than natural biomaterial bone.
