장종성,이혜영,이미영 대한물리치료학회 2012 대한물리치료학회지 Vol.24 No.3

Purpose: The purpose of this study was to investigate the lumbar erector spinea and rectus abdominis activations, according to the different gait velocities in young healthy adults. Methods: We recruited 6 young male and 10 young female (mean age=21.43 years; range 19~23) in this study. We used a wireless surface electromyogram (Telemyo 2400T G2, Noraxon, USA) and a treadmill unit for the experiment. EMG activity from the lumbar erector spinea, and rectus abdominis of the dominant side was record with surface electrodes. On different day, all subjects gaited on 2.7 km/h, 4.5 km/h, and 6.3 km/h of speed in random order. They gaited at the same velocity, three times, on the treadmill unit. To reduce fatigue, sufficient rests were given between the measurements. Results: As the gait speed increased, lumbar erector spinea and rectus abdominis activations were significantly increased (p<0.05). Conclusion: In the current study, we found lumbar erector spinea and rectus abdominis activations were changed, according to the gait velocity. We suggested that rehabilitation intervention should be focused on the exercise velocity for the patients with problem of the trunk control.

장종성,이전형 대한물리치료학회 2015 대한물리치료학회지 Vol.27 No.1

Purpose: The purpose of this study is to investigate differences of cervical flexor muscle thickness (i.e., sternocleidomastoid muscle anddeep cervical flexor muscles) depending on levels of pressure bio-feedback unit and eye directions during cranial-cervical flexor exercisein healthy subjects. Methods: A total of 30 subjects (12 males and 18 females) who had no medical history related to musculoskeletal and neurological disorderswere enrolled in this study. They were instructed to perform cranial-cervical flexion exercise with adjustment of five different pressures(i.e., 22 mmHg, 24 mmHg, 26 mmHg, 28 mmHg, and 30 mmHg) using a pressure biofeedback unit, according to three different eyedirections (i.e., 0°, 20°, and 40°). Muscle thickness of sternocleidomastoid muscle and deep cervical flexor muscles was measured accordingto pressure levels and eye directions using ultrasonography. Results: In results of muscle thickness in sternocleidomastoid muscle and deep cervical flexor muscles, the thickness of those muscles wasgradually increased compared to the baseline pressure level (22 mmHg), as levels in the pressure biofeedback unit during cranial-cervical flexionexercise were increasing. In addition, at the same pressure levels, muscle thickness was increased depending on ascending eye direction. Conclusion: Our findings showed that muscle thickness of sternocleidomastoid muscle and deep cervical flexor muscles was generally increasedduring cranial-cervical flexion exercise, according to increase of eye directions and pressure levels. Therefore, we suggested thatlower eye direction could induce more effective muscle activity than the upper eye direction in the same environment during cranial-cervicalflexion exercise.

Purpose: The purpose of this study was to compare plantar foot pressure distribution in adults and elderly according to obstacle height. Methods: Nine healthy adults and nine older adults were recruited and the subjects provided written informed consent consent prior to participation. Both groups walked and crossed obstacles with heights of 0%, 10%, 20%, and 30% of their height. Foot pressure was measured by peak pressure using the Pedar System (Novel Gmbh, Germany) during obstacle walking with barefeet in shoes. Three trails were calculated on eight areas and then averaged for data analysis. Results: A significant difference in great toe, little toes, and lateral metatarsal area was observed between adults and elderly groups, but other areas did not show significant differences. Foot pressure was increased in groups according to obstacle height. Conclusion: These findings showed that change in foot pressure distribution is more lateral in elderly in order to maintain postural control during obstacle crossing.

Purpose: To examine the correlation between the gait speed and muscle activation or foot pressure in stroke patients. Methods: Twenty five functionally ambulant stroke patients (male/female: 15/10, mean age: $57.65\pm2.30$) were enrolled in this study. The patients were asked to walk on a plate at a self-selected and comfortable speed. Three walking trials were obtained and then averaged for data analysis. The gait speed and foot pressure were measured from a RS-Scan system. Activation of the quadriceps femoris muscle and biceps hamstring muscle (%RVC) were recorded using ProComp $Infiniti^{TM}$. Results: There was a significant positive correlation between Hamstring muscle activation (%RVC) and gait speed. The gait speed correlated with the foot pressure of the lateral metatarsal zone (M3-5) in the affected side. There was a correlation between the gait speed and the foot pressure of the lateral metatarsal (M3-5) and heel (medial, lateral) zone in the less-affected side. Conclusion: The gait speed is related to hamstring muscle activation and the characteristics of foot pressure. This information was observed in both the affected and less-affected sides, suggesting that rehabilitation programs should be implemented on both sides.

PURPOSE: The Unilateral neglect is characterized bydifficulty shifting attention to the side of space opposite thebrain lesion and frequently reducing use of contralesionalextremities. This study was to identify whether the visualdeprivation was responsible for head position on unilateralneglect patient after stroke.METHODS: A patient with left middle cerebral arteryinfarction participated in the study. We assessed neglect usingline bisection and star cancellation test. Patient was instructedto maintain correct alignment of trunk and head in a sitposition. We evaluated degree of head lateral tilting androtation. Then, patient was blocked visual input. Also, weevaluated head position in the same way.RESULTS: He scored 3 points in the line bisection test and9 points star cancellation test. In postural evaluation, he haddeviated posture such as lateral head tilting and rotation. Aftervisual cue deprivation, patient showed different head positionwhich was decreased degree of head tilting and rotation.CONCLUSION: For vertical body orientation, it wasused multiple sensory references including the vestibular,somatosensory, and visual system. This finding suggestedthat abnormal posture of neglect patient could be related to thevisual input. It has important clinical implications in terms ofunderstanding the neglect.
