RESUMO
Objective To explore the impact of intrapartum mild asphyxia on motor development in infants. Methods 30 infants with any of the following were as asphyxia group:heart rate more than 160 beats/min in the process of childbirth, and then down to 70-80 beats/min, no cyanose;Apgar score 1 min more than 8. Other 30 normal infants were as control group. They were assessed with Neuropsychologi-cal Development Scale for 0-6 Years Old 3, 6 and 9 months after birth. Results Opisthotonos was more frequent in the asphyxia group than in the control group (P0.05). Sitting forward was more frequent in the asphyxia group 6 months after birth, and the score of motor was less in the asphyxia group than in the control group (P<0.05). More of the asphyxia group couldn't stand with help, and with poor motor score 9 months after birth (P<0.05). Conclusion Intrapar-tum mild asphyxia may infulence the motor development of infant in long-term.

Results Opisthotonos was more frequent in the asphyxia group than in the control group (P<0.01) 3 months after birth, but there was no significant difference in total score (P>0.05). Sitting forward was more frequent in the asphyxia group 6 months after birth, and the score of motor was less in the asphyxia group than in the control group (P< 0.05). More of the asphyxia group couldn't stand with help, and with poor motor score 9 months after birth (P<0.05).

RESUMO
STUDY DESIGN: Cross sectional study. PURPOSE: To evaluate characteristics of back muscle strength in patients scheduled for lumbar fusion surgery. OVERVIEW OF LITERATURE: Little is known regarding muscle strength in patients with symptomatic lumbar degenerative diseases who require fusion surgery. METHODS: Consecutive 354 patients scheduled for posterior lumbar interbody fusion due to symptomatic degenerative diseases were approached for participation. 316 patients were enrolled. Before surgery, muscle strength was assessed by measuring maximal isometric extension strength at seven angular positions (0degrees, 12degrees, 24degrees, 36degrees, 48degrees, 60degrees, and 72degrees) and mean isometric strength was calculated. The Oswestry Disability Index (0-100) and visual analogue scale (0-100) for back pain were recorded. Muscle strength was compared according to gender, age ( or =70 years) and scheduled fusion level (short, or =3). RESULTS: Isometric strength was significantly decreased compared with previously reported results of healthy individuals, particularly at extension positions (0degrees-48degrees, p0.05). Isometric strengths showed significant, but weak, inverse correlations with age and Oswestry Disability Index (r<0.4, p<0.05). CONCLUSIONS: In patients with symptomatic lumbar degenerative diseases, back muscle strength significantly decreased, particularly at lumbar extension positions, and in females and older patients.
