The purpose of this study was to examine the effects of hip abductor fatigue on static balance and gait in the general population. Design: One group pre-test post-test design. Methods: Thirteen university students in their twenties volunteered for the study and had underwent a functional assessment. To induce fatigue, the subjects were instructed to raise their dominant lower extremity up against a load of 50% of 1 repetition maximum... -

a very high fall risk. The duration of the BBS is approximately 15 minutes and evaluates both static and dynamic balance abilities. The therapist who performed the BBS before and after inter- vention had greater than 3 years of experience in the clinic.

All subjects were assessed with the Medical Research Council (MRC), the Berg Balance scale (BBS), Timed Up and Go test (TUG), and 10-meter walk test (10MWT) pre and post intervention. Results: The MRC, BBS, TUG, and 10MWT scores significantly improved post-intervention (p<0.05), and the control group also had significantly improved in all areas post-treatment (p<0.05). In addition, it has been confirmed that the additional... -

pain.’’ Examinees marked the position to assess their own pain levels ranging from “0” in- dicating no pain, to “10” indicating severe pain under each item of the questionnaire. The test-retest have been shown to be high reliability (r=0.95) [15]. Weight distribution This research used a plantar foot pressure analysis (Foot Checker; GHiWell, Korea) to estimate the pressure dis-... controlled trial. Methods: Twenty patients in the early stage of rehabilitation after knee surgery were recruited as subjects and were randomly divided into either experimental group (exercise combined with NMES) (n=10) or control group (n=10). Both groups received strength training of the lower limb for 20 min/day, 5 days/week for 4 weeks. The experimental group used NMES for unilateral quadriceps femoris training with incremental increases in the intensity of isometric contraction over 4... -

Patients in both groups were instructed to walk as fast as they could along a 35 m long track (straight for 20 m and curved for 15 m). Patients walked with their hemiplegic side on the inside of the track while a physical therapist followed along to instruct patients to maintain a straight posture. Balance ability was tested with the Functional Reach Test, the Timed Up and Go... -

the muscles and cardiovascular system due to a lower static component of the exercise. If dynamic ex- ercise is conducted slowly, there is a considerable isometric component to the exercise that causes fuel use to switch to carbohydrates with light exercise and making the exercise inefficient [47,50]. If exercise is conducted, even at the same oxygen uptake, more quickly and with less loading... treadmill, elliptical track and bicycle ergometry. The later 3 forms of exercise were accomplished in four, 5 minute bouts at different intensities of exercise. Subjects were in the age range of 22-24 years old, were free of cardiovascular disease and did not have any neurological injuries. They were not sedentary and exercised at least twice a week. During the exercise, muscle activity was measured by the electromyogram recorded by surface electrodes on 6 muscle groups. A Cosmed metabolic cart... -

The acoustic-mechanical vibration and energy transmission through the middle ear in normal and diseased ears can be visualized and quantified in a 3-dimensional FE model. Four novel model-derived “auditory test curves” named as the middle ear transfer function, energy absorbance, admittance tympanogram, and tympanic membrane holography are generated with clinically relevant applications. -

An impact load of 3.44 kg, corresponding to 23.62 J, was applied to the center of each plate supported at the boundaries. The unidirectional composite plate showed the worst impact resistance and broke completely into two parts; this was followed by the quasi-isotropic lay-up plate that was perforated by the impact. The cross-ply composite plate... -

Dynamic evaporation studies indicated that a droplet deposited on the treated flms evaporated in the constant contact angle Fig. 7. Preparation procedure of FP modi ed MWCNTs and Illustrating the changes of water contact... Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -
