JOURNAL FREE ACCESSThe purpose of this study was to investigate the effect of short duration stretching for prevention of disuse muscle atrophy under anesthesia in mature rats. Fourteen male Wistar rats (weight: 522±62g) were divided into experimental and control groups. Disuse muscle atrophy in experimental group was induced by hindlimb suspension (HS) for two weeks. Non-elastic tape was used to maximally stretch the right soleus muscle (SOL) by dorsiflexing the ankle joint under anesthesia for 20 min a day, 5 times a week, during the period of HS. The left SOL was left unstretched. Control rats were only anesthetized without HS. Muscle adenosine triphosphatase (ATPase) histochemical staining, followed by morphometric analysis, demonstrated that mean cross-sectional area of muscle fiber in stretched SOL was significantly greater than that in unstretched SOL (both type I and II). No differences in muscle weight and the percentage distribution of muscle fiber type were observed between stretched and unstretched SOL. The results suggest that progression of disuse muscle atrophy in mature rats can be attenuated, but not completely prevented, by maintaining stretched position for 20 min a day.View full abstractDownload PDF (831K)

JOURNAL FREE ACCESSThe purpose of this study was to examine the relationship between neonatal behavioral assessment and mental-motor development at 12 months. The subjects were 77 low birth-weight infants. We examined them by Brazelton Neonatal Behavioral Assessment Scales (NBAS) at 44 weeks gestational age, and by Bayley Scales of Infant Development (BSID) at 12 months corrected age. The multiple regression analysis was performed with Bayley Scales, Mental score (MDI) and Motor scores (PDI) as objective and NBAS 8 cluster scores as explanatory variables. As a result, NBAS 8 cluster scores proved to have a strong influence on the Bayley Scales (MDI: R^2=0.58 p<0.001, PDI: R^2=0.61 p<0.001). Bayley Scales at 12 months corrected age could be explained 60% from 8 NBAS cluster scores. Calculation of standard partial regression coefficient revealed 'Motor cluster score (MDI: β=0.377 p<0.001, PDI: β=0.285 p<0.01 )', 'State Range cluster score (MDI: β=0.279 p<0.01, PDI: β=0.254 p<0.01)' and 'Reflexes cluster score (MDI: β=-0.271 P<0.01, PDI: β=O.478 p<0.001)' to have significant influences on Bayley Scales as objective variables. These results indicate that NBAS is very useful for the early assessment of neonatal risk status and early intervention planning.View full abstractDownload PDF (434K) -

JOURNAL FREE ACCESSTo restore gait performance in two complete paraplegics, the closed-loop control system was introduced to multi-channel functional electrical stimulation by use of percutaneous electrodes, combined with ankle-foot orthosis and an L-walker. In both patients, the functional status of closed-loop control was observed. The patients could stand up and sit down stably. They were able to walk continuously with reciprocating gait for 20 and 25 meters at gait velocities of 0.02 m/sec and 0.03m/sec, respectively. In reconstructive standing-up and locomotion therapy using functional electrical stimulation, muscle fatigue caused by electrical stimulation is one of the major problems. Reducing the amount of electrical stimulation needed to stimulate muscles can be achieved using closed-loop control. Our results suggest that complete paraplegics can stand-up and walk reciprocally by way of functional electrical stimulation with the closed-loop control system.View full abstractDownload PDF (777K) -

JOURNAL FREE ACCESSHip abductor torques of 27 hemiplegic patients and 31 healthy controls were measured by a portable weight modulator (Load cell) in order to examine the relationship with the maximum walking velocity. A high positive correlation was observed between body weight and hip abductor torques in both sides. The patients of Brunnstrom stage V or VI showed higher hip abductor torques, compared with those of III or IV. The walking velocities of the patients of Brunnstrom stage III or IV and V or VI were one-third and one half of those of healthy controls, respectively. In the patients of Brunnstrom stage V or VI, a high positive correlation was observed between walking velocity and hip abductor torque. These results suggest that a high hip abductor torque may result in pelvic stability during standing phase of affected limbs, which allowed unaffected limbs to step smoothly, consequently inducing higher walking velocity.View full abstractDownload PDF (571K)

JOURNAL FREE ACCESSCongenital fiber type dysproportion (CFTD) is a rare disease causing hypotonia and muscle weakness in patients in early infancy following the onset of clinical symptoms. The symptoms have either improved or remain the same after the age of two. In this study therapeutic exercise to improve anti-gravity posture was undertaken by a young girl with CFTD for 44 months, starting at the age of 29 months. At the age of two, symptoms showed signs of improvement. Crawling on all fours became possible at 47 months, and walking alone at 63 months. Slow development of motor function was noted.View full abstractDownload PDF (1107K)

JOURNAL FREE ACCESSIn August 1995, four physical therapists and one occupational therapist worked as volunteer with two doctors in Bentre Province in the Mekong Delta, Vietnam. A per capita national income in Vietnam is 200 dollars, while that in Bentre Province is 96 dollars. Although there are 2,507 handicapped children in the province, whose population is 1.31 million, almost 70% of those children do not receive medical treatment because of poverty and a lack of doctors and physical therapists. There are three training schools for physical therapists in Hanoi, Danang and Ho Chi Minh City, respectively. However, since there is no national examination system to become a physical therapist, the number of physical therapists in the country is unknown. About 150 physical therapists around Ho Chi Minh City organize the Ho Chi Minh City Physical Therapy Association, whose activity is focused on postgraduate clinical education.View full abstractDownload PDF (1213K)
