Purpose: The purpose of this study was to evaluate the effect of computerized neurocognitive function program on cognitive function about memory and attention with stroke. Methods: 24subjects with stroke were recruited. Twelve of subjects received conventional therapy including physical therapy, occupational therapy and language therapy. Another subjects received additional computer assisted cognitive training using Computer-aided Cognitive rehabilitation training system(COMCOG, MaxMedica Inc., 2004). All patients were assessed their cognitive function of memory and attention using Computerized Neurocognitive Function Test(CNT, MaxMedica Inc., 2004) before treatment and 6 weeks after treatment. Results: Before the treatment, two groups showed no difference in cognitive function(p>0.05). After 6 weeks, two groups showed significantly difference in digit span (forward, backward), verbal learning(A5, $A1{\sim}A5$), auditory CPT(n), visual CPT(n)(p<0.05). After treatment, the experimental group showed a significant improvement of digit span(forward, backward), verbal learning(A5, $A1{\sim}A5$), visual span (forward, backward), auditory CPT(n, sec), visual CPT(n, sec), and trail-making (A, B)(p<0.05). Conclusion: Computerized neurocognitive function program would be improved cognitive function of memory and attention in patients with stoke.

The cause of poor visual acuity was connected to the damage by the ocular trauma related. Especially the most cause of visual disorder was identified as irregular pupil by ocular damage. Therefore most patients stopped the wearing of the contact lens immediately by the visual decrease effects from irregular pupil disorder. But we had suggested that the contact lens wear was a very intensive visual therapy. We had identified the visual recover from several tests using the contact lens treatment.

PURPOSE: The purpose of our study was to compare a 975-nm, 500-mW GaAlAs low-level laser therapy versus placebo low-level laser therapy with regard to the immediate changes on the myofascial trigger point of the dominant upper trapezius muscle in subjects with rounded shoulder posture. METHODS: Thirty-two male college students with rounded shoulder posture and shoulder pain consented to participate in the experiment. The subjects were randomly assigned to a 2-minute procedure with either an active GaAlAs low-level laser or a placebo GaAlAs low-level laser. The pressure-pain threshold and visual analog scale on tenderness at 3 kg were measured with an algometer before and after the laser treatments. RESULTS: The active GaAlAs low-level laser group showed significant changes in pressure-pain threshold and visual analog scale on tenderness at 3 kg (p<0.05). The placebo GaAlAs low-level laser group showed no significant changes in either pressure-pain threshold or visual analog scale on tenderness at 3 kg (p>0.05). CONCLUSION: An immediate effect was observed in pressure-pain threshold and visual analog scale on tenderness at 3 kg following a 2-minute application ($857.14J/cm^2$) of a 975-nm, 500-mW GaAlAs low-level laser to the myofascial trigger point of the dominant upper trapezius muscle in patients with rounded shoulder posture.

Objective: The purpose of this study was to investigate the effects of providing visual feedback and auditory stimulation using a robotic device on balance and gait abilities in stroke patients. Design: Randomized controlled pilot trial. Methods: Fifteen subjects were randomly divided into three groups where five subjects were in the visual feedback robotic device assist gait training (VRGT) group, five subjects in the auditory stimulation robotic device assist gait training (ARGT) group, and five subjects in the control group. Subjects received visual feedback and auditory stimulation while undergoing robotic gait training for 45 minutes, three times a week for 2 weeks, and all subjects had undergone general physical therapy for 30 minutes, five times a week for 2 weeks. All subjects were assessed with the Berg balance scale (BBS), timed up and go (TUG) test, and 10-meter walking test (10MWT) pre- and post-intervention. Results: All subjects showed that BBS, TUG test, and 10MWT scores significantly improved post-intervention (p<0.05), and the control group also had significantly improved post-treatment (p<0.05). The VRGT and the ARGT showed significant improvements in BBS, TUG, and 10MWT scores compared with the control group (p<0.05). The VRGT group showed a significant improvement in BBS, TUG, and 10MWT scores compared with the control group (p<0.05). In addition, it has been confirmed that VRGT had significantly improved in BBS, TUG test, and 10MWT scores compared with the auditory stimulation and control group (p<0.05). Conclusions: The results of this study showed improved balance and gait abilities after VRGT and ARGT groups compared with general physical therapy and was found to be effective in enhancing the functional activity of persons affected with stroke.

Physical therapists have been using biofeedback training to induce improvements in various circumstances. The purpose of this study was to compare the effects of visual and tactile feedback using electrical stimulation on quadriceps strength. Nineteen women without known impairment of the neuromusculoskeletal system volunteered for this study. Subjects were randomly allocated into three groups: visual feedback, tactile feedback, and control group. The torque of isometric knee extension force was measured. Subjects were asked to exert the maximal isometric contraction force of quadriceps over a 30 second period. The resting period of 10 minutes was given after the maximal isometric contraction to avoid the muscle fatigue. In between groups comparison, significant differences of the peak torque and the torque area were found on the performance of the maximal isometric contraction of quadriceps (p<.05). The values peak of torque and torque area were significantly higher during visual feedback than tactile feedback. The results of this study suggest that visual feedback is more powerful than tactile feedback (p<.01).
