Purpose: The purpose of this study was to examine the electromyographic (EMG) activity of the abdominal muscles and to compare the activity ratios of the bilateral rectus abdominis (RA) to oblique abdominal muscles during shoulder abduction in opposite directions with single leg raising (SLR) performed in the supine position on a foam roller. Methods: Fifteen healthy subjects were recruited to the study. Each subject lay on the foam roller and performed left single leg raising with right or left shoulder $90^{\circ}$ abduction (Abd); performed in a random order. Surface EMG recordings of selected abdominal muscles (i.e., the RA, external oblique abdominis [EO], internal oblique abdominis [IO], and transverse abdominis [TrA]) were normalized to maximum voluntary isometric contraction. EO/RA and IO and TrA/RA ratios were determined with surface EMG. Data were analyzed by Independent t-test. The statistical significance level was p<0.05. Results: The results were as follows: (1) the right RA, left EO, and right IO and TrA muscle activities increased significantly at the left SLR with left Abd compared to the left SLR with right Abd (p<0.05); and (2) the ratio of right EO/RA activity increased significantly at the left SLR with right Abd compared to left Abd (p<0.05). Conclusion: These findings suggest that left SLR with left Abd on a foam roller is an appropriate exercise for activation of specific oblique abdominal muscles.

Purpose: The purpose of this study was to investigate the effect that trunk stability exercises with stabilizing reversal and rhythmic stabilization of PNF have on trunk strength and balance ability in stroke patients. Methods: This study included 20 stroke patients who performed trunk stability exercises combined with stabilizing reversal and rhythmic stabilization of PNF. The exercise program consisted of 30-minute sessions per week for six weeks. Trunk strength (BTE, Primus RS) and balance ability (Berg Balance Scale) were evaluated before and after training. All data were analyzed using SPSS 18.0 software. Results: Significant differences were observed the both groups for truck strength and balance ability. The results of the study were as follows: trunk strength was significantly increased in both groups (p<.05) and it was also found to be significant between groups after the intervention (p<.05). Balance ability was significantly increased in both groups (p<.05) and it was also found to be significant between the groups after intervention (p<.05). Conclusion: Trunk stability exercises with stabilizing reversal and rhythmic stabilization of PNF are effective for improving trunk strength and balance ability in stroke patients. For stroke patients, trunk stability exercises with PNF are very useful and effective and they areeffectiveinclinicalpractice.

Purpose: This study aimed to investigate spatial and temporal features of motor control in an individual with hemiparesis during the curvilinear gait (CG) and proposed an exercise guideline. Research design, data and methodology: An individual aged 63 with hemiparesis by stroke disease was participated in the study. Autoencoder (AE) was used to extract four motor modules from eight muscle activities of the paretic leg during CG. After extraction, each module of four modules was operationally defined by numbering from M1 to M4 according to spatial and temporal features and compared with results reported in a previous study. Results: As a result, an individual with hemiparesis had motor module problems related to difficulty of weight acceptance (module 1), compensation for the weakness of ankle plantar flexor (module 2), a spastic synergistic pattern (module 3) and difficulty with transition from the swing to stance phase (module 4) in terms of spatial features. Also, a delayed activation timing of temporal motor module (module 2) related to the forward propulsion during CG was observed. Conclusions: Gait rehabilitation for the stroke will need to consider clinical significances in respect of the deterioration of motor module and provide the tailored approaches for each gait phase.

When any damage or disease occurs, muscular strength and muscular endurance are lowered, and thus, if one is able to be restored from the damage or the disease, appropriate stimulus is required, since the muscles have to restore their proper functions. For such stimulus, the way of exercising and the way using electric stimulus are used in physical therapy. In order to examine the change in muscular strength, muscular endurance and girth of limbs for Biceps brachii, according to the lands of stimulus, in this article a total of 42 healthy male and female adults in their twenties were randomly sampled, and a series of tests were conducted for 6 weeks, for 15 minutes per once, 3 times per week, respectively, dividing them into the group for RUS(Russian Current Stimulation), PRE(Progressive Resistive Exercise) and P+R(RUS + PRE). The findings showed that the change in muscular strength was most significant as for the group for P+R, since it increased from $62.12{\pm}25.30$ before experiment to $95.78{\pm}34.07$ after 6 weeks: the change in muscular endurance was most significant as for the group for P+R, since it increased from $17.57{\pm}6.63$ to $42.86{\pm}10.24$; and the change in the girth of limbs was slightly significant only in the group for P+R, and the remaining two groups showed no significance.

The purpose of the present study was to the investigate the effect of aging in men and women on muscle strength of knee extensor and flexors by using the cybex 6000 isokinetic dynamometer. A total of 100 volunteers participated in this study and were divided into five groups according to their chronological age as follows: 20s, 30s, 40s, 50s, 60s, 10 men and 10 women in each decade respectively. Isokinetic ($60^{\circ}{\cdot}s-l$) knee extensor and flexor peak torque, peak torque to body weight ratio, opposing muscles(flexor/extensor) peak torque ratio, deficit of peak torque between dominant and non-dominant were measured. The results obtained were as follows: 1) In men, While the aged increased. the peak torque of the knee flexor and extensor statistically sig nificant decreased in the dominant and non-dominant side. 2) In women, Statistically significant difference of knee extensor peak torque was found as the aged increased in the dominant and non-dominant side, but significant difference of knee flexor peak torque did not that. 3) In men, No significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the non-dominant side, but statistically significant difference in the peak torque of knee flexor to body weight weight ratio was found as the aged increased in the dominant side. 4) In women. No significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the dominant side, but statistically significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the non-dominant side. 5) In men and women, While the aged increased, statistically significant difference was found the dominant and non-dominant side in the peak torque of knee extensor to body weight ratio. 6) Peak torque of hamstring to quadriceps ratio of dominant and non-dominant side in men and women were not significantly different as the age increases. 7) Mean deficit of peak torque between dominant and non-dominant side in men and women were not significantly different as the age increases. From these results we conclude a proper exercise program is need before 50s decade to preserve in muscle strength of knee flexors and extensors.

슬관절의 퇴행성 관절염에서 슬관절 전치환술은 널리 시행되고 있고 그 빈도도 점점 증가되고 있다. 수술 후 일상생활로의 복귀, 근력 및 운동범위의 회복 등 기능 회복을 위한 노력이 이루어져야 하고 이는 환자 요인, 수술 술기 및 재활 등 다양한 관점에서 접근해야 한다. 환자의 연령이나 비만의 정도, 성별, 대퇴사두근의 근력 등이 수술 후 기능 회복에 영향을 줄 수 있고 환자의 기대치나 만족도 같은 정신적인 상태도 영향을 준다. 기능 회복을 위하여 수술 전부터 환자교육 및 통증 조절, 대퇴사두근 근력의 강화 같은 치료를 시행할 수 있다. 수술 후 냉찜질 및 압박, 경피적 전기 신경 자극 치료, 신경근육 전기 자극 치료, 저주파 저강도 자기장 치료, 대퇴사두근의 근력운동, 관절범위 운동과 같은 물리치료도 적용할 수 있다. 최근에는 수중에서 근력과 균형감각을 회복시키는 수 치료도 점점 시행되는 추세이다. 이런 기능 회복을 위한 치료들은 수술 후 단기적으로만 시행될게 아니라 장기적으로 꾸준히 시행되는 것이 중요하며 술자는 환자의 상태나, 순응도, 사회적, 심리적 상황 등을 고려하여 적절히 적용하여야 한다.
