For elderly people, an advanced training machine that uses actuator and can adjust load according to muscle activity is proposed. The proposed machine allows users to have a safe and effective training through exercise close to ordinal motion appears in daily life such as stretching or stooping motion. A muscle activity sensor real-timely monitors the activation level of user's muscle during the exercise and the training load is adjusted based on the measured data. The training load is exerted and continuously controlled by electric/pneumatic actuator.

Objective: The aim of this study was to investigate the effect of balance training with plantar flexor stretching on ankle dorsi flexion range of motion (ROM), balance, and gait ability in stroke patients. Design: A randomized controlled pilot trial. Methods: Thirty stroke patients volunteered to participate in this study. The subjects were randomly allocated to two groups: the experimental group (n=15) received the neurodevelopment therapy plus balance training with plantar flexor stretching for 20 minutes in one session. The control group (n=15) received the same neurodevelopment therapy plus plantar flexor static stretching for 20 minutes in one session. Both groups underwent sessions four times a week, for a total of 4 weeks. Measurements included passive range of motion (PROM), active range of motion (AROM) of ankle dorsiflexion using a goniometer, timed up and go (TUG), the functional reaching test (FRT), and the 10 m walk test (10 MWT). Results: There were significant improvements in AROM and PROM of ankle dorsiflexion, TUG, and FRT scores after the intervention in the experimental group (p<0.05). However, the control group showed no statistically significant differences except for PROM of ankle dorsiflexion. The experimental group showed a significant improvement in PROM, TUG, and FRT scores compared to the control group (p<0.05). Conclusions: Balance training with plantar flexor stretching improves ankle dorsiflexion ROM and balance ability in patients with stroke. Therefore, this therapeutic intervention will be effective for rehabilitation of stroke patients in the clinical setting.

Delayed onset muscle soreness is a sensation of discomfort that occurs 24h after exercise, and it is associated with the performance of unfamiliar and high force muscle wor, such as eccentric contractions. The injury to the muscle has been well described but the mechanism underlying the injury is not fully understood. Although the pathophysiological processes underlying delayed onset muscle soreness are not completely understood, many researchers have investigated various treatments in a attempt to reduce the soreness. These treatments have focused on reducing the inflammation, or edema, consequent to tissue damage, and breaking up the cycle which is thought provoke tonic muscle spasm or pain. Physical therapy is the most importance thechniques to reduce delayed onset muscle soreness. Physical therapy on delayed onset muscle soreness includes massage, exercise, therapeutic ultrasound, TENS, stretching and cryotherapy, this investigation should encourage physical therapists to experiment further with various techniques to reduce delayed onset muscle soreness.

Piriformis muscle syndrome is a condition that causes direct muscle pain around piriformis muscle or sciatica from irritated sciatic nerve and the diagnosis remains debatable. The main treatment is symptomatic relief from conservative therapy such as medication and piriformis stretching exercise, and various therapeutic injections including local anesthetic, corticosteroid, botulinum toxin can be considered for diagnostic and therapeutic purposes. In this case, a 54-year-old male who had sciatica and gait disturbance showed piriformis muscle hypertrophy in the pelvis MRI. From imaging studies, electrodiagnostic study and physical examination, he was diagnosed with piriformis muscle syndrome. He underwent trigger point injection and botulinum toxin injection into the piriformis muscle, and pain and gait disturbance significantly improved. This case reports a case of piriformis muscle syndrome with clinical symptom of gait disturbance, which was improved by botulinum toxin injection.

This study was intended to implement ankle joint dorsi flexion training against ankle muscule strength weakening that erodes stroke patients' gait performance to examine the effect of the training on stroke patients' plantar pressure and gait ability. In this study, 36 stroke patients diagnosed with stroke due to cerebral infarction or cerebral hemorrhage were divided to measure 10MWS which are stroke patients' gait variables maximum plantar pressure by area of the sole by collecting data using an F-scan system during gait. Given these results of the study, compared to other training groups, the ankle muscule strength reinforcing training group showed statistically significant increases of maximum plantar pressure in the great toe, the toe and the first metatasal areas too and thus it can be said that this training increases forward thrust during stroke patients' foot end taking off and positively affects stroke patients' ability to perform gait.

Background: The purpose of this study is to investigate the effect of muscle energy technique and stretching on pain and pressure pain fear-avoidance beliefs questionnaire in patients with chronic back pain aged 30~40 years. Design: Pretest-Posttest design: single blind. Methods: The subjects of this study were 30, 22 males and 8 females between the ages of 30 and 40 with chronic back pain. Each group consists of three groups of 10 people. Changes in back pain were observed using Korean version of Oswestry Disability Index (K-ODI), visual analogue scale (VAS), and fear-avoidance beliefs questionnaire (FABQ). And the change in tenderness was observed using digital pressure statistics. Changes between groups after 3 weeks were compared with those before the experiment using one way ANOVA to determine the changes after 3 weeks. And the change within the group was investigated using the paired t-test. Results: As a result of the experiment, there were significant differences in the group changes in K-ODI, VAS, FABQ, and pressure pain (p<0.05). And there was a significant difference in all items after 3 weeks compared to before the experiment (p<0.05). Conclusion: In patients with chronic back pain, the muscle energy technique and stretching gave a significant difference in pain and pressure pain, fear-avoidance beliefs questionnaire changes. And this result suggests the possibility of providing basic data for future research and clinical physiotherapy intervention.
