The purpose of this study was to evaluate the effect of joint mobilization and manual stretching exercises in patients with hallux valgus. Twenty-three participants were divided into two groups; joint mobilization (n=11) and manual stretching exercises (n=12). The subjects participated in the experiment for 15minutes, three times a week, four weeks. The joint mobilization (Grade III, Maitland) was performed to experimental group for a minute and then rested for 10 seconds for each set. The manual stretching was performed to control group with three exercise session (preparatory and finishing exercises, agonist contraction exercises, agonist contraction and hold-relax exercises). In the results of the study, intragroup comparison of the deformity angles (DA) was shown to decrease from $15.18^{\circ}$ to $13.09^{\circ}$ in the joint mobilization group (p<.05) and from $19.00^{\circ}$ to $16.83^{\circ}$ in the stretching exercises group (p<.05). However, left static foot pressure (LSFP), right static foot pressure (RSFP), left dynamic foot pressure (LDFP) and right dynamic foot pressure (RDFP) did not significantly increase or decrease after the experiment. Intergroup differences also were not statistically significant in all variables (p>.05). The current study suggests that JM and MSE are effective in decreasing the DA in patients with hallux valgus.
Purpose : The purpose of this study was to find out The effect of Low back pain on the total pattens of Proprioceptive neuromuscular facilitation(PNF). Methods : The subjects of the study were 62 low back pain patients. They were divided into two groups: 31 in the experimental group and 31 in the control group. the experimental group performed modalities and PNF total patterns three times for a week. the control group performed only modalities and ROM exercise three times for a week. Back muscle strength was measured by a back muscle strength measuring machine, the intensity of pain was measured by the Visual Analogue Scale (VAS), and the level of disability was measured by Oswestry low back pain disability index. Study measurements were compared before and after 6 weeks exercise program. The two groups of subjects were assessed by utilizing two different balance measurement: Static standing balance was measured by balance performance monitor (BPM) and Dynamic standing balance was measured by one leg standing(OLS). The scale for static standing balance was measured by using, sway area, sway path, max velocity. Results : The results of this study were as follow: 1) The score on visual analogue scale shows statistically significant increase on PNF group of post test(p<.05). 2) The score on Oswestry low back pain disability index. shows statistically significant decrease on PNF group of post test(p<.05). 3) The change sway area was statistically significant on pre-test and post-test(p<.05). 4) The change sway path was statistically significant on pre-test and post-test(p<.05). 5) The change max velocity was statistically significant on pre-test and post-test(p<.05). 6) The score on one leg standing shows statistically significant increase on PNF group of post test(p<.05). Conclusion : These results of this study indicated that Proprioceptive Neuromuscular Facilitation Total patterns which performed for six weeks had a statistically significant influence on low back pain. If the exercise for muscle strength is performed along with therapeutic stabilizing exercise, a better effect can be expected on low back pain. We hope that this study will provide a basic data for further research with a bigger group and on a long-term effect.

PURPOSE: The purpose of this study were to determine an intervention that involves proprioceptive exercises combined with cognitive task completion for adults with chronic ankle instability and to investigate the effects of the exercises on the static balance, dynamic balance, and ankle function of such individuals. METHODS: A total of 30 adults suffering from the aforementioned condition were randomly divided into experimental (n=15) and control (n=15) groups. The experimental group performed proprioceptive exercises in combination with cognitive tasks for 15 minutes in each session that was held three times a week for four 4 weeks, whereas the control group carried out only proprioceptive exercises. A Wii Balance Board, which enables examining the fluctuation area distance, and speed, was used to determine static balance; a Y-balance test kit was employed to measure dynamic balance; and the side hop, figure-of-8 hop, and square hop tests were conducted to ascertain ankle function. RESULTS: The results showed that the static balance, dynamic balance, and ankle function of both the experimental and control groups significantly improved. The participants were instructed to perform one-leg postural exercises with and without vision blocking for the affected leg. The experimental group showed more significant improvement than did the controls in terms of the fluctuation distance, speed, and area of static balance. CONCLUSION: In conclusion, although combined proprioceptive exercises and cognitive tasks were insufficient to enhance all types of balance among the subjects, it effectively reinforced their static balance.

PURPOSE: Stroke patients have limited ankle range of motion and balance problems. The purpose of this study was to determine the effects of Kaltenborn orthopedic manual therapy, Evjenth-hamberg stretching, and combination of both on ankle dorsiflexion range of motion and dynamic balance ability in stroke patients. METHODS: Thirty patients were placed in three groups, each of which received different treatments: Kaltenborn orthopedic manual therapy (15 mins), Evjenth-hamberg stretching (15 mins), or Kaltenborn orthopedic manual therapy with Evjenth-hamberg stretching (30 mins). Each group received three exercise sessions per week during four weeks. To determine its effectiveness of interventions an evaluation was carried out. ankle dorsiflexion range of motion was gauged using a tiltmeter application, and dynamic balance ability was measured using the Berg balance scale. RESULTS: All groups revealed significant improvements in ankle dorsiflexion range of motion, Berg Balance Scale (BBS) score before and after the intervention, and Kaltenborn orthopedic manual therapy with Evjenth-hamberg stretching group showed a significant improvement in ankle dorsiflexion range of motion and BBS score in comparison to other groups. CONCLUSION: We found out that each individual method was effective in ankle dorsiflexion range of motion, dynamic balance ability in stroke patients, and the combined method was more effective.
Purpose: The aims of this study were to determine if game-based training with constraint-induced movement therapy (CIMT) is effective in improving the balance ability in female patients with a total knee replacement, and to provide clinical knowledge of CIMT game-based training that allows the application of total knee replacement. Methods: Thirty-six patients who had undergone a total knee replacement were assigned randomly to CIMT game training (n=12), general game training (n=12), and self-exercise (n=12) groups. All interventions were conducted 3 times a week for 4 weeks. All patients used a continuous passive motion machine 5 times a week and 2 times a day for 4 weeks. The visual analog scale (VAS), muscle strength of knee flexion and extension, and range of motion (ROM) of knee flexion and extension were assessed, and the functional reach test (FRT), and timed up and go (TUG) test were performed to evaluate the balance ability. Results: All 3 groups showed significant improvement in the VAS, knee flexion and extension muscle strength, FRT, and TUG test after the intervention (p<0.05). Post hoc analysis revealed significant differences in FRT, and TUG of the CIMT game training group compared to the other group (p<0.05). Conclusion: Although the general game training and CIMT game training improved both the knee extension muscle strength and dynamic balance ability, CIMT game training had a larger effect on dynamic balance control.
Background: Many studies have reported positive results of the various mirror training and virtual reality games in improving dynamic standing balance and posture adjustment in chronic stroke patients. However, no systematic study has been conducted to compare the effects of virtual reality games and the mirror balance training. Objects: The purpose of this study was to compare the effectiveness of Wii balance games and Mirror Self-Balancing Exercises in improving proprioception of knee joint and standing balance of people with chronic stroke. Methods: Twenty patients with chronic stroke volunteered for this study. The subjects were randomly divided into a Wii balance games group and a Mirror Self-Balancing Exercises group with 10 patients in each group. Each training was performed for 30 mins a day for 4 days. In addition to the balance training, 30 mins neuro-developmental-treatment based routine physical therapy was given to both groups. Proprioception was measured using two continuous passive motion devices, and static balance was measured using a Wii balance board. Dynamic balance assessment tools included the Berg Balance Scale, Dynamic Gait Index, and Timed Up-and-Go test. Results: All measured variables before and after the experimental results showed a significant improvement in both groups (p<.05). Only the improvement of the affected knee proprioception appeared to be significantly greater in the Wii balance game group (p<.05). However, other variables did not differ between the groups (p>.05). Conclusion: The findings suggest that both Wii balance games and Mirror Self-Balancing Exercises may be helpful for improving the proprioception of knee joint and the balance of patients with chronic stroke.
To meet the increasing demand from various fishing fields for training of fishing equipment operators, a fishing winch simulator was designed to train maritime students in the correct and safe operation of hydraulic winches under various load conditions related to fishing operations. The aim of this study is to describe the basic dynamic characteristics of the newly developed hydraulic fishing winch simulator and particularly to analyze the mechanical responses produced on the winch operation controls. The winch simulator consists of two winch units, a computer control and data acquisition system, a control consol and other associated mechanisms. When one winch is in hauling mode, the other one will always be in loading mode. The revolution speed of the hauling winch was controlled by a proportional directional control valve, and the braking torque of the loading winch was controlled by a proportional pressure control valve. The simulation experiments indicated that the dynamic characteristics of the hauling winch followed the braking response characteristics of the loading winch. The tests also showed that the warp speed and tension linearly depend on the pressure differential across the motor of the loading winch controlled by operating the proportional pressure control valve during the hauling operation. The experience gained from various training courses showed that the fishing winch simulator was very realistic and it was valuable for training novice winch operators. The results of the winch simulation exercise were recorded and used to evaluate the training on the operation and handling of the winch system. From these test results, we concluded that the tension acting on the warp during hauling operations can successfully be simulated by controlling the pressure differential across the motor with step changes of the control input signal to the proportional pressure control valve of the loading winch.
Objective: The aim of this study was to determine the peak torques of the knee and ankle joint and local stability of the lower extremity's joints, and muscle activation patterns of the lower extremity's muscles between fallers and non-fallers in the elderly women during walking. Method: Four elderly women (age: $74.5{\pm}5.2yrs.$; height: $152.1{\pm}5.6cm$; mass: $55.3{\pm}5.4kg$; preference walking speed: $1.19{\pm}0.06m/s$) who experienced falls within six months since experiment had been conducted (falls group) and thirty-six subjects ($74.2{\pm}3.09yrs.$; height: $153.6{\pm}4.9cm$; mass: $56.7{\pm}6.4kg$; preference walking speed: $1.24{\pm}0.10m/s$) who had no experience in falls (non-falls group) within this periods participated in this study. They were measured torque peaks of the knee and ankle joint using a Human Norm and while they were walking on a treadmill at their natural pace, kinematic variables and EMG signals were collected with using a 3-D motion capture system and a wireless EMG system, respectively. Lyapunov Exponent (LyE) was determined to observe the dynamic local stability of the lower extremity's joints, and muscles activation and their co-contraction index were also analysed from EMG signals. Hypotheses between falls and non-falls group were tested using paired t-test and Mann-Whitey. Level of significance was set at p<.05. Results: Local dynamic stability in the adduction-abduction movement of the knee joint was significantly lower in falling group than non-falling group (p<.05). Conclusion: In conclusion, muscles which act on the abduction-adduction movement of the knee joint need to be strengthened to prevent from potential falls during walking. However, a small number of samples for fallers make it difficult to generalize the results of this study.
