The purpose of this case study is to describe the experience of two children who have sensory defensiveness and to guide further study of sensory defensiveness treatment. The subjects were two children with sensory defensiveness and aged 8 and 3. It was used Sensorimotor History Interview for the evaluation of sensory defensiveness and interviewed with parents. The Wilbarger protocol in this case study was included jump-ing and crushing on the bed as routine activity in every morning and bedtime, a Wilb-arger brush with very firm pressure and joint compression per 2 hours when subjects had waked up and occupational therapy 1 to 3 times per week. According to this case study, the subjects had decreased defensive behaviors for sen- sation of touch, vision, sound and taste, and social emotional problems. During the treatment, the sleep cycle was changed and more stabled to sleep. And the optimal arousal level was more maintained for wake up period.

Occupational therapists often employ multidimensional tasks. These tasks, referred with necessary exercise, yet direct the focus of attention toward another objective or outcome. The assumption is that the additional purpose will result in improved task per- formance, provided it is sufficiently distracting or meaningful to the person. The pres- ent study examined the effects of an added purpose task on performance compared with a single-purpose task, namely rote exercise, as measured by the number of repetitions, task duration, and exercise heart rate. Stoppage during the activity was also recorded. Thirty-nine elderly subjects performed both added purpose activity and rote exercise in randomly assigned order. Results indicated that the added-purpose, occupationally em- bedded exercise condition elicited significantly more exercise repetitions(p=.001), and longer task duration than did the rote exercise condition (p=.000). This study provides additional support for the traditional occupational therapy concept of embedding exer- cise within occupation.
