Purpose: We investigated to identify the effect of robo-horseback riding exercise (RHRE) on trunk muscle activity ratios for patients with low back pain. Methods: Twelve patients with low back pain and twelve healthy adults were recruited for this study. Subjects performed the RHRE with the neutral spine position. The amplitude of electromyography activity was recorded from the selected trunk muscles (internal oblique [IO], rectus abdominis [RA], multifidus [MF], the thoracic part of the iliocostalis lumborum [ICLT]). The ratios of the relative local muscle activity to the global muscle activity in abdominal and lumbar parts were calculated. Results: There were significant differences in the change values of the IO/RA and the MF/ICLT between low back pain (LBP) patients and healthy adults. The IO/RA ratio and the MF/ICLT ratio showed significant increase in LBP patients after training. Conclusion: The RHRE improved the trunk muscle activity ratio in patients with low back pain. The information presented here is important for investigators who use lumbar stabilization exercises as a rehabilitation exercise.

A case of a 38 year-old woman with histrionic personality who had chronic epigastric pain, dyspepsia and alternating bowel habit for more than 10 years was presented in detail on its course of two times of admission and follow-up. The diagnosis was thought as psychophy-siological disorder or gastrointestinal motility disorder of undefined etiology rather than hypo-chondriasis or Briquet's syndrome. She was characterized by sustained illness behavior and combined several physical illnesses. i.e. tuberculosis. anemia and hepatic stone. These physical diseases led to a blurring of psychological and physical boundaries regarding symptom formation. The points on consultation from medical part to psychiatric department were discussed and the supposed causal mechanisms in non-organic functional gastrointestinal disturbances were also reviewed. Physical and psychological modalities for the treatment and the abnormal illness behavior were mainly emphasized in this case.

We have studied to apply of a quantity of SBR contained high and domestic tire cord on manufacture tire. The Physical test of compounds and products, the travelling test of manufactured tires last year had revealed a good results. 1. The physical properties indicated better values than those found in the requirments of military specification. 2. Adhesion of carcass ply cord showed a good results. 3. The physical properties between 1260 d/2 nylon cord and 840d/2 nylon cord of domestic products be showed similar values and its have a results by 2-3 times than standards.

Although many current low back pain exercise incorporate proprioceptive training, very little research has been performed on proprioception of the low back. To determine wether reposition error is different in male than female. Eighteen young individuals took part in the research, seven male and eleven female. The 3-dimensional position of the lumbar was measured with a CMS70P. Reposition error was calculated as the absolute difference between the neutral position and return position. No significant differences in reposition error were found between male and female. No significant correlations were identified between reposition error and movement direction.

The following are suggested joint distraction and gliding techniques for use by entry level therapists and those attempting to gain a foundation in joint mobilization. A variety of adaptations can be made from these techniques. The distraction and glide techniques should be applied with respect to the dosage, frequency, progression, precautions, and procedures as described in this section. Basic concepts of joint mobilization were presented, including definitions of terminology and the two grading systems. Joint mobilization techniques are one part of a total treatment for decreased function. Therapy should also include appropriate range of motion, strengthening, and functional techniques.

Hydrotherapy is aimed at evoking short-term and long-term adaptation-mechanisms of patients. This means that a patient should be able to adapt to the changed environment. both mentally and physically. Hydrotherapy is widely used to treat patients with generalised rheumatic discases. Hydrotherapy may be applied as a single therapy. in combination with other therapeutic interventions or as one pan of a complex series of stimuli as e.g. during spa therapy. A treatment regimen in water is constructed according to the same rules as dry land exercise. However, methods specifically designed or adjusted for hydrotherapy can be used. The Halliwick is suitale in particular to facilitate arthrokinetic reactions as a part of training postural stability. The Bad Ragaz Ring is a hydortherapy modification of proprioceptive neuromuscular facilitation. Patterns of arms. logs and trunk are used to increase muscle function and flexibility. Other techniques are applicable in water too: mobilization and manipulation techniques of the joints can be integrated in hydrotherapeutic methods. The continuous research is needed for many interesting issues of hydrotherapy in new future.

The technology of gait analysis is moving rapidly. Human gait is very complex, and a through understanding of it demands with the basic principles of biomechanics and the technology used to measure gait. Some professionals reluctance to use gait analysis may be due to the amount of time and effort necessary to accomplish this and the necessity for teamwork among the disciplines involved. Any form of observational gait analysis has limited precision and is more descriptive than quantative. The techniques of 3-D kinetic and kinematic analysis can provide a detailed biomechanical description of normal and pathological gait. This article review gait characteristics and procedures that are available for gait analysis. We are certain that, given the steady advance of technology and our continued efforts to document the benefits of that technology. gait analysis will soon be a routine part of the evaluation of both the elite athlete and the physically impaired adult or child.

As a series of the studies of EPDM-Polymer blends, the experiments are concentracted to the investigation of the physical properties of the EPDM-NBR blends. The results are shown as follows; 1. As EPDM addition ratio is increased, the physical properties such as resistance to ozone and aging have also improved, on the other hand, elongation and abrasion resistance decreased. 2. Tear strength is less influenced by blending and character after aging exhibited the same result. 3. Tensile strength decreased with increase in EPDM contents, especially the ratio of EPDM/NBR are 50/50 and 75/25.

Until the up to day, we have known that a tight iliotibial tract has an influence on the patella, pulling it laterally and causing pain in patients with patellofemoral syndrome, so should be stretched as a part of physical therapy. But the iliotibial tract's function on the patella in subjects with PFS has not yet been proved and further questions need to be answered regarding the evaluation or treatment of a tight tract in patients with PFS.

As a series of the studies of EPDM-Polymer blonds, the experiments are concentrated to the investigation of the physical properties of the EPDM-CR blends. The results are shown as follows: 1. In blending, tensile strength decreased with increase in EPDM contents and decreasing value was good results than various EPDM blending. 2. As EPDM Addition ratio is increased physical properties such as elongation have also improved, on the other hand, hardness and abrasion resistance decreased. 3. Aging resistance is less influenced by blending. 4. Tear strength is less influenced by blending and character after aging exhibited the same result. 5. Ozone resistance was much improved after blending. It was effective more than the ratio of EPDM/CR is 25/75.
