        Background: After stroke, in order to improve gait function, it is necessary to increase the muscle strength and to enhance the propriocetive function of the lower extremity. Objects: This study aimed to compare the effects of open kinetic chain (OKC) versus closed kinetic chain (CKC) isokinetic exercise of the hemiparetic knee using the isokinetic equipment on lower extremity sensorimotor function and gait ability in patients with chronic stroke. Methods: Thirty participants with chronic hemiplegia (> 6 months post-stroke) were randomly divided into 2 equal groups: CKC group and OKC group. Patients from both groups attended conventional physiotherapy sessions 3 times a week for 6 weeks. Additionally, subjects from the CKC group performed isokinetic exercise using the CKC attachment, while those from the OKC group performed isokinetic exercise using the OKC attachment. The isokinetic knee and ankle muscles strength, position sense of the knee joint, and spatiotemporal gait parameters were measured before and after interventions. Results: The knee muscles peak torque/body weight (PT/BW) and hamstring/quadriceps (H/Q) ratio significantly increased in both groups (p<.01). In particular, ankle plantarflexors PT/BW, position sense of the knee, gait velocity, and spatial gait symmetry significantly improved in the CKC group (p<.01, p<.05, p<.01, and p<.01, respectively). Conclusion: CKC isokinetic exercise can be an effective therapeutic intervention for the improvement of sensorimotor function of the lower extremity and gait functions, such as gait velocity and symmetry. CKC position in isokinetic strength training is effective to improve functional ability in patients with chronic stroke.

        Background: Improvement of the lumbo-pelvic stability can reduce the compensatory action of the erector spinae (ES) during prone hip extension (PHE). Furthermore, the application of abdominal drawing-in (ADI) maneuver increases the action of gluteus maximus (GM) and decreases the action of ES during PHE by improving the lumbo-pelvic stability. However, the post-ADI exercise effects on PHE, not the real-time application of ADI maneuver, has not been studied. Objects: This study is aimed at investigating the post-ADI exercise effects on the muscle activities of GM and ES during PHE. Methods: A total of 24 female adults participated in the study, and they were divided into two groups: Those with normal abdominal muscles (n1=12) and those with weak abdominal muscles (WA) (n2=12). Before the intervention, the subjects’ GM and ES muscle activities during PHE were measured. Subsequently, the two groups were asked to perform the ADI exercise for 10 minutes. After the ADI exercise, the GM and ES activities were equally measured during PHE. Results: The comparison result of the ES muscle activities before intervention shows a significant difference between the two groups (p<.05); the WA group showed higher muscle activities than the normal group. For the within-group comparison, the muscle activities of the ES in the WA group significantly decreased after the ADI exercise (p<.05). For the GM muscle activity, no significant difference was observed in all comparisons (p>.05). For the changes in muscle activities before and after the ADI exercise, a significant difference exists between the two groups only for the changes in ES activities (p<.05); WA group exhibits higher changes than the normal group. By contrast, no significant difference exists between the two groups for the changes in GM activities (p>.05). Conclusion: After the ADI exercise, the compensatory action of ES in the female adults with WC is implied to decrease during PHE.

        Background: In previous studies, changes in postural alignment were found when the slope was changed during walking. Downhill walking straightens the trunk by shifting the line of gravity backward. Objects: This study investigated the effect of the downhill treadmill walking exercise (DTWE) on thoracic angle and thoracic erector spinae (TES) activation in subjects with thoracic kyphosis. Methods: A total of 20 subjects with thoracic kyphosis were recruited for this study. All the subjects performed the DTWE for 30 minutes. A surface EMG and 3D motion capture system were used to measure TES activation and thoracic angle before and after the DTWE. Paired t-tests were used to confirm the effect of the DTWE (p<.05). Results: Both the thoracic angle and TES activation had significantly increased after the DTWE compared to the baseline (p<.05). An increase in the thoracic angle indicates a decrease in kyphosis. Conclusion: The DTWE is effective for thoracic kyphosis patients as it decreases their kyphotic posture and increases the TES activation. Future longitudinal studies are required to investigate the long-term effects of the DTWE.

        Background: Chronic low back pain (CLBP) causes morphological changes in muscles, reduces muscle strength, endurance and flexibility, negatively affects lumbar stability, and limits functional activity. Plank exercise strengthens core muscles, activates abdominal muscles, and improves intra-abdominal pressure to stabilize the trunk in patients with CLBP. Objects: We investigated the effect of plank exercise on abdominal muscle thickness and disability in patients with CLBP. Methods: We classified 33 subjects into 2 groups: An experimental (n1=17) and a control group (n2=16). Patients in the experimental group participated in plank exercise and those in the control group participated in stretching exercise. Patients in both groups attended 20-minute exercise sessions thrice a week for 4 weeks. Abdominal muscle thickness in each subject was evaluated ultrasonographically, and disabilities were assessed using the Oswestry disability index (ODI). Results: Four weeks later, abdominal muscle thickness showed a significant increase over baseline values in both groups (p<.05). Patients in the experimental group reported a more significant increase in the thickness of the external oblique muscle than that in the control group (p<.05). ODI scores in the experimental group were significantly lower after intervention than before intervention (p<.05). Conclusion: Plank exercise increases the thickness of the external oblique muscle and reduces disability secondary to mild CLBP. Therefore, plank exercise is needed to improve lumbar stability and functional activity in patients with mild CLBP.

        Background: Stroke is one of the most common diseases responsible for physical disabilities. In addition to their physical and occupational therapy, the self-exercise programs were developed for patients with hemiplegia to increase the intensity of their therapeutic exercise. Objects: The purpose of this study was to assess the effect of a customized self-exercise program (CSP) to walking function on improving stroke survivors’ muscle strength and ambulation function. Method: To test the effect of the self-exercise program, the following tests were conducted: The functional ambulation category (FAC), Tinetti performance-oriented mobility assessment gait part (POMA-G), timed up and go (TUG), 10-meter walk, and 2-minute walk. The study included 161 consenting stroke patients (FAC score>1) from a randomized, screened sample of 217. The CSP group participated in a 30-minute CSP each day for 10 weeks in addition to completing a routine rehabilitation program. The control group received only a routine rehabilitation program. All the subjects were monitored by a therapist once a week and had to submit an exercise checklist at the end of each session. Result: The strength of the participants’ upper and lower extremity muscles showed no significant differences between the CSP group and the control group. The FAC score and POMA-G also showed no significant differences. However, there were significant differences in the TUG, 10-meter walk test, and 2-minute walk test (p<.05). Conclusion: The findings of this study suggest that a CSP may improve gait-related function in stroke survivors.

        Background: Compared to healthy people, patients with chronic lower back pain have reduced balance abilities which may cause proprioception problems, patients with chronic lower back pain avoid physical activities due to pain, and reduced activity levels lead to muscle weakening, which can further exacerbate pain. Recently, there have been many studies on the use of sensory stimulation; and among these studies, interventions that use vibrational stimulation have shown functional improvements in the patients. Objects: This study examined the effects of a stabilization exercise with vibration stimulation on the balance ability and disability in patients with chronic back pain. Methods: The subjects of the study were 30 persons who were randomly assigned to the experimental group and the control group, with 15 subjects in each. The subjects were evaluated before and after intervention via a balance ability test, the Korean Oswestry disability index (KODI) test, a pain test, and a proprioceptive sensory test. Both groups received general physical therapy. The experimental group performed the stabilization exercise with vibration stimulation, and the control group performed a general stabilization exercise, three times a week for six weeks. Results: After the intervention, both groups showed significant improvements in the balance ability test, the KODI test, the pain test, and the proprioceptive sensory test. The experimental group showed statistically significant, higher improvements than the control group in the balance ability test, the KODI test, and the proprioceptive sensory test. Conclusions: The stabilization exercise with vibration stimulation for patients with chronic back pain has been reported to provide greater functional improvements than the conventional intervention method. Therefore, the stabilization exercise in a vibration stimulation environment could be a useful intervention for patients with chronic back pain.

        The purpose of this study was to identify the effect of proprioceptive neuromuscular facilitation (PNF) stretching exercise and joint mobilization on ankle joint range of motion (ROM), plantar pressure, and balance in subjects with stroke. Thirty patients (n=30) were organized into three groups, each of which received different treatments: PNF stretching (n=10), joint mobilization (n=10), and joint mobilization and PNF stretching combined (n=10). Each group received three exercise sessions per week for four weeks. The ankle ROM was measured using a goniometer, and plantar pressure and balance ability were measured using BioResque static posturography. In comparison within each group, the joint mobilization group and the joint mobilization with PNF stretching group showed significant improvements in ankle ROM, plantar pressure, and balance ability (p<.05). In comparison between the groups, a statistically significant difference was found in SECS change between the PNF stretching group, joint mobilization group and the joint mobilization with PNF stretching group. This study found demonstrates that the joint mobilization and joint mobilization with the PNF stretching methods were effective in improving ankle ROM, plantar pressure, and balance ability in stroke patients.

        The purpose of this study was to investigate the effects of sling exercise on muscle activity and balance on football players with chronic ankle instability. Eight subjects performed Biodex and sling exercises for four weeks and compared the muscle activity and balance ability of the uninjured and injured feet. Stable and unstable foot % MVIC did not change significantly after treatment in all muscles. The total balance ability was not significantly different between the two groups, however, increased only in the unstable side. The anterior/posterior balance ability also represented no significant difference between the groups and was significantly improved only in the unstable side. The medial/lateral balance ability was not significantly different between the groups and was significantly improved only in the unstable side. This study suggests that sling exercise contributes to improving % MVIC, total balance ability, anterior/ posterior balance ability, and medial/lateral balance ability of the unstable side.

        Background: We developed a novel integrative lumbar stabilization technique that combines lumbar extension (LE) exercise with abdominal drawing-in maneuver (ADIM) to ameliorate low back pain (LBP) associated with neuromuscular imbalance and instability, based on the collective evidence of contemporary spinal rehabilitation. Objects: The specific aim of the present study was to investigate the effects of LE exercise with and without ADIM on core muscle strength, lumbar spinal instability, and pain, as well as functional characteristics in individuals with LBP using advanced radiographic imaging techniques. Methods: patients with mechanical LBP (N = 40, 6 males; 35.1±7.6 years) were recruited and randomly assigned either to the combined LE and ADIM (experimental group) or the LE alone (control group). Outcome measures included the visual analog scale, the modified Oswestry Disability Index, muscle strength imbalance (MSI), and radiographic imaging. The lumbar intervertebral displacement (LID), intervertebral (IV) and total lumbar extension (TLE) angles were calculated to evaluate the lumbar segmental instability. Results: The experimental group showed significant differences in the L3-L4, L5-S1 LIDs, L4-L5 and L5-S1 IV angles, and TLE angle as compared to the controls (p<.05). Immediate pain reduction and muscle strength imbalance ratio were significantly different between the groups (p<.05). Conclusion: These results suggest that the addition of ADIM significantly increased lumbar spinal stabilization in individuals with LBP, thereby reducing pain associated with functional lumbar flexion during daily activities.

        Background: Round shoulder posture, results from excessive flexed posture of the thorax, is defined as a position of scapular protraction, anterior tipping, and downward rotation. However, previous studies have focused on only passive position of the thorax during scapular posterior tilting (SPT) and have not reported on SPT combined with correction of flexed posture. Objects: The aim of this study was to compare effects of SPT and SPT with prone trunk extension (SPT + PTE) on activities of the lower trapezius, serratus anterior, and thoracic erector spinae and degree of posture in subjects with round shoulder and flexed posture. Methods: Fifteen subjects with round shoulder and flexed posture were recruited. The caliper was used to measure the degree of round shoulder and flexed posture. Electromyography was performed to collect data of muscle activities. Paired t-test was used to compare two exercise (α=.05). Results: When SPT + PTE was applied, the degree of round shoulder posture (p=.001) and flexed posture (p=.039) significantly decreased compared with that when SPT was applied. The lower trapezius activity significantly increased in the SPT + PTE condition compared with that in the SPT condition (p=.026). There were no significant differences in serratus anterior activity between SPT + PTE and SPT. The thoracic erector spinae activity significantly increased in the SPT + PTE condition compared with that in the SPT condition (p=.014). Conclusion: SPT + PTE might be one of the effective methods to enhance activities of lower trapezius and thoracic erector spinae, and to reduce round shoulder posture and flexed posture in subjects with round shoulder and flexed posture.

        고강도 운동 시 산성화의 과정은 수소이온의 방출과 젖산 나트륨염을 형성하는 젖산의 생산 증가에 따른 것이라 설명되어져 왔다. 이 설명에 의하면, 젖산의 생산 비율이 세포내의 수소이온 완충능력을 초과하였을 때 세포의 수소이온 농도는 증가한다고 한다. 이러한 생화학적 과정을 젖산의 산성화라 한다. 이 이론에 따라 고강도 운동 시 젖산의 생산이 대사적 산성화와 피로의 원인이 되는 것으로 해석되어져 왔다. 그러나, 본 고찰에서는 젖산의 생산이 산성화와 피로의 원인이라는 어떠한 생화학적 근거가 없음을 명확히 제시하고 있다. 오히려 젖산의 생산은 해당과정에서 필요한 NAD+의 지속적인 공급을 위해 필수적이며 수소이온을 소비하는 대사과정이다. 젖산의 축적은 세포와 혈중의 수소이온 농도의 증가를 알려주는 좋은 지표가 될 수는 있지만 그것이 산성화의 직접적인 원인은 아니다.

        목적 : 본 연구는 저항운동으로 6주간 적용된 혀-유지 메뉴버 프로그램이 Shaker 운동 프로그램과 비교하여 정상성인의 삼킴 근육 활성도에 미치는 영향을 알아보고자 하였다. 연구방법 : 2015년 10월부터 12월까지 10대에서 50대의 건강한 성인 26명을 대상으로 혀-유지 메뉴버 그룹과 Shaker 운동 그룹으로 무작위 할당하여 주 5일, 하루 1회, 30분씩 6주간 적용하였다. 표면근전도를 사용하여 설골상근 (suprahyoid muscle)과 설골하근(infrahyoid muscle)에 대한 근활성도를 수집하였다. 시각적 비율척도(Visual Analog Scale), 자각인지 척도(Borg-Rating of Perceived Exertion Scale) 척도를 사용하여 삼킴 시 노력과 피로를 측정하였다. 결과 : 혀-유지 메뉴버 그룹과 Shaker 그룹 모두 설골상근과 설골하근의 근활성도가 유의한 향상을 보였지만, 두 그룹 간의 유의한 차이는 없었다. 또한 두 그룹 모두 삼킴 시 노력 및 피로가 통계학적으로 유의한 차이를 보였으나, 두 그룹 간의 유의한 차이는 없었다. 결론 : 건강한 성인을 대상으로 6주간 혀-유지 메뉴버를 통해 삼킴 근육 근활성도에 대한 긍정적인 효과를 확인하였다. 향후에는 삼킴장애 환자를 대상으로 혀-유지 메뉴버에 대한 임상적 효용성을 검증하여 유용한 치료기법으로 사용되기를 기대한다.
