A case of spinal cord injury that occurred in utero.

Spinal cord injury is a rare occurrence that is often difficult to diagnose. This report describes a 2-year-old male with cervicothoracic spinal cord injury. The injury is thought to have occurred in the fetal period because the patient's thorax was markedly hypoplastic at birth and his mother had noticed a decrease in fetal movements for several weeks before the birth. The deep tendon reflex of the upper and lower extremities was absent at birth, as observed in other cases of spinal cord injury. It was noteworthy that deep tendon reflex of the upper and lower extremities remained decreased at 2 years of age despite the injury being located at C(7)-T(1). Based on this case, we propose that spinal cord injuries occurring in utero display different reflex responses from those occurring at birth.

[Adaptive behavior scale for persons with profound intellectual disability].

An adaptive behavior scale for persons with profound intellectual disability was proposed. This scale consisted of 64 items from five areas: interpersonal relationship, perception, expression, interest and play, and daily life. Each item was scored on a 0-2 scale. Forty-eight institutionalized persons (23 males, 25 females) with profound intellectual disability, aged 13-69 (mean 40) years, were examined with this scale. The rating for each item was 0.02-1.81 (mean 0.88). On 69% of the items, estimates were consistent between two care-staffs. The Cronbach's alpha value was calculated to be 0.97, indicating good internal consistency. On the whole, this scale is useful in assessing adaptive behaviors of the subjects.

Clinical profiles of children with cerebral palsy having lesions of the thalamus, putamen and/or peri-Rolandic area.

Neurological findings, motor symptoms, mental abnormality and dysarthria were examined in 28 children with lesions in the thalamus, putamen, and/or peri-Rolandic area. The thalamus and putamen were involved in eight, and only the thalamus in ten of the children. Most of these 18 children had mild disabilities; they did not have severe mental retardation and could walk alone, speak words, and grasp an object. Dominant flexion of the hips was observed in many of the children who could walk. Two-thirds of these children had athetotic involuntary movement and the remaining had gross or fine motor abnormalities although they had no involuntary movement. In most of these children, reaching patterns were abnormal and were affected by shoulder retraction. Their abnormal movements were thought to be inappropriate muscle activity brought about by voluntary movements. In the remaining ten children, the thalamus, putamen, and peri-Rolandic area were all involved. Many had severe disabilities such as severe mental retardation and the inability to sit, speak words, or grasp an object. All had athetotic involuntary movements. Three children had spasticity of the lower extremities. Five children with severe disabilities and no spasticity were thought to have apparent weakness with athetosis.

[Adaptive behavior scale for persons with severe physical and mental disability].

An adaptive behavior scale for persons with severe physical and mental disability was proposed. This scale consisted of 43 items from five areas; interpersonal relationship, perception, expression, interest and play, and daily life. Each item was scored on a 0-2 scale. Eighty-two persons (52 males, 30 females) with severe physical and mental disability, aged 1-49 (mean 20.2) years, were examined with this scale. They were institutionalized or attended a day care center. The rating for each item was 1.60-0.09 (mean 0.75). The Cronbach's alpha value was calculated to be 0.95, indicating good internal consistency. For 39 persons attending a center, estimates were consistent between the mother and care staff on only 61% of the items, showing insufficient inter-rater reliability. On the whole, this scale is useful in assessing adaptive behaviors of the subjects.
