The aim of this study was to compare the electromyographic (EMG) activity levels of the scapular upward rotators [upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA)] and other scapular muscles [posterior deltoid (PD), levator scapulae (LS), and infraspinatus (IS)] during isometric lower trapezius exercises. Twenty males with no medical history of shoulder pain or upper extremity disorders were recruited for this study. EMG activity was recorded from the UT, LT, SA, PD, LS, and IS while subjects performed three different exercises: Prone arm lift (PAL), Backward rocking diagonal arm lift (BRDAL), Modified Prone Cobra (MPC). One-way analysis of variance (ANOVA) was used to determine any significant differences among the three exercises. A lower relative activation of UT, LT, and SA was seen with the MPC than with the other exercises (p<.05). The relatively lower activation of the UT identified, the MPC exercise as the preferred choice for preferential strengthening the LT (p<.05). However, a higher activation in the PD, LS, and IS occurred with the MPC than with the other exercises (p>.05). The recruitment pattern of synergist varied depending on the exercise posture. These findings suggest that exercise posture is an important factor in the selection of strengthening exercise for weak muscle.

Purpose: The current study seeks to identify the effect of neck muscle strengthening exercise using proprioceptive neuromuscular facilitation (PNF) on the swallowing ability of patients diagnosed with dysphagia due to stroke. Methods: As a single case study, the current research conducted neck muscle strengthening exercise using PNF on the patient with dysphagia for 40 minutes, four times per week for a six-week period. At the same time, typical rehabilitation therapy for dysphagia was provided. This type of therapy included food-swallowing and the relation of the muscles surrounding the neck. The functional dysphagia scale and the penetration-aspiration scale were used to assess swallowing ability. Results: After the therapy, the functional dysphagia scale and the penetration-aspiration scale decreased by 18 points and 3 points, respectively, which proves the effectiveness of this type of therapy for dysphagia. Conclusion: The results of the current study indicate that neck muscle strengthening exercise using PNF reduces penetration-aspiration in patients with dysphagia, and that PNF can be clinically utilized to improve the swallowing ability of dysphagic patients.

Background: Plantar fasciitis is one of the most common conditions of the lower limbs. The present study aimed to compare the effect of hip muscle strengthening exercise and stretching of lower extremity in plantar fasciitis, with regard to pain, navicular drop and foot and ankle functional ability. Methods: A total of 42 patients diagnosed with plantar fasciitis were randomly assigned to the experimental group (n=21) that applied the hip muscle strengthening exercise and the control group(n=21) that applied the general lower limb stretching. The intervention period was 6 weeks. Results: The results of the experiment showed that the exercises for strengthening the hip muscle had significant effects on pain, navicular drop and foot and ankle functional ability In addition, lower extremity stretching showed improvement effects in pain, navicular drop and foot and ankle functional ability, however, the difference between the groups except navicular drop did not reach statistical significance Conclusion: Both interventions tested in this study were confirmed to be effective treatment options for patients with plantar fasciitis.

This research was designed to investigate how the exercise program affects paraplegic standing and walking employing functional electrical stimulation(FES). Emphasis was also given to fatigue of major lower extremity muscles induced by different types of electrical stimulation. We applied continuous and intermittent rectangular pulse trains to quadriceps of 10 normal subjects and 4 complete paraplegic patients. The frequencies were 20Hz and 80Hz, and the knee angle was fixed at 90$^{\circ}$and 150$^{\circ}$to investigate how muscle fatigue is related to muscle length. The knee extensor torque was measured and monitored. We have been training quadriceps and gastrocnemius of a male paraplegic patient by means of electrical stimulation for the past two year. FES standing was initiated when the knee extensors became strong enough to support the body weight, and then the patient started FES walking utilizing parallel bars and a walker. We used an 8-channel constant-voltage stimulator and surface electrodes. The experimental results indicated that paralyzed muscles fatigued rapidly around the optimal length contrary to normal muscles and confirmed that low frequency and intermittent stimulation delayed fatigue. Our exercise program increased muscle force by approximately 10 folds and decreased the fatigue index to half of the initial value. In addition, the exercise enabled the patient to voluntarily lift each leg up to 10cm, which was of great help to the swing phase of FES walking. Both muscle force and resistance to fatigue were significantly enhanced right after the exercise was applied every day instead of 6 days a week. Up to date, the patient can walk for more than two and half minutes at 10m/min while controlling the on/off time of the stimulator by pushing the toggle switch attached to the walker handle.

The aim of this study was to determine the effect of a non-elastic fixation belt on the balance ability and fall prevention in elderly women. Elderly women experience reduced balance ability and an increased risk of falls due to a weakening of the surrounding sacroiliac joint and pelvic muscles during childbirth and menopause. On the other hand, specific studies are still needed. The subjects were allocated randomly to two groups: control (n=20) and experimental (n=20). The experimental group used a non-elastic fixation belt, whereas the control group had no fixation belt. The balance ability and the fall index were measured in all subjects using a balance measurement device, and the low abdominal muscle thickness was determined in the experimental group using ultrasound imaging for the exact application of the non-elastic fixation belt. The following statistical analysis was performed: an independent t-test for the general characteristics of the subjects, $2{\times}2$ analysis of variance with repeated measures for the balance and fall index score, and a paired t-test for the abdominal muscle thickness. The group ${\times}$ time interaction effect showed significant improvement in the General Stability Index (F1,38=47.24, p=0.001), Fourier Harmony Index (F1,38=88.83, p=0.001), Weight Distribution Index (F1,38=50.21, p=0.001), and Fall Index (F1,38=21.59, p=0.001). The thicknesses of the transverse abdominal (p=0.001) and internal oblique (p=0.001) muscles were increased significantly in the experimental group after using the non-elastic fixation belt. Overall, the application of a non-elastic fixation belt could be effective in improving the balance ability and fall prevention in elderly women.
