The purpose of this study was to examine the effect of the angle of a wedged insole on knee varus torque during walking. Fifteen healthy subjects were recruited. Knee varus torque was measured using three-dimensional motion analysis (Elite). Knee varus torque was normalized to gait cycle (0%: initial contact; 100%: ipsilateral initial contact) and stance phase (0%: initial contact; 100%: ipsilateral toe off). The average peaks of knee varus torque during the stance phase of the gait cycle according to the different insole angles (10 or 15 degrees) were compared using one-way ANOVA with repeated measures. The results showed that in the early stance phase, the average peak knee varus torque increased significantly for both the medial 10 and 15 degree wedged insole conditions and decreased significantly for both the lateral 10 and 15 degree wedged insole conditions as compared with no insole (p<.05). However, there were no significant differences between the 10 and 15 degree wedged insole conditions with either the medial or lateral wedged insole (p>.05). In the late stance phase, the average peak knee varus torque increased significantly for the medial 10 and 15 degree wedged insole conditions (p<.05), but not for the lateral 10 and 15 degree wedged insole conditions as compared with no insole (p>.05). We suggest that these results may be beneficial for manufacturing foot orthotic devices, such as wedged insoles, to control medial and lateral compartment forces in the knee varus-valgus deformity. Further studies of the effects of wedged insole angle on knee varus torque in patients with medial-lateral knee osteoarthritis are needed.

The kinematics involved in different landing strategies may be related to the occurrence of trauma. Several sources suggest that the angle of knee extension on touchdown and impact with the ground determines the magnitude of the impact force and, indirectly, knee loading. This study compared the initial knee angle and maximum knee flexion angle at the instant of impact on drop-landings between healthy men and women. In this study, 60 participants (30 males, 30 females) dropped from a height of 43 cm. A digital camera and video motion analysis software were used to analyze the kinematic data. When landing, there was significant difference between the two groups ( in male, in female) in the mean knee flexion angle. The range of knee flexion on landing ( in male, in female) also differed significantly (p<.05). The greater knee flexion that was observed in the male subjects would be expected to decrease their risk of injury. Women land with smaller range of knee flexion than men and this might increase the likelihood of a knee injury.

Objective : To compare the value of basic activities of daily living between occupational therapists and patients with stroke. Methods : A questionnaire survey was conducted to investigate the relative importance of basic ADL (Activities of Daily Living) with a total of thirty-four item cards. The survey was completed by 36 occupational therapists that have clinical experience of more than three years in a hospital or rehabilitation settings and by 38 inpatients/outpatients with stroke. The relative importance of each activity of daily living was measured by the Q sorting technique. A Mann-Whitney U test was used to test the statistical significance of the mean difference in the Q score between the occupational therapists and the patients with stroke. Results : Among the 34 items, 11 items (‘obtaining and using supplies’, ‘selecting clothing’ etc.) selected by inpatients, showed that the Q score was significantly higher in its importance than that of occupational therapists. The survey showed that ‘caring for nails’ was more im-portant to outpatients than it was to occupational therapists. Several items (18 items for in-patients, 3 items for outpatients) of the total 34 items were statistically significantly different on the value of the basic ADL between occupational therapists and patients with stroke. Conclusion : The relative value of each activity of daily living could serve as a guide for sequencing learning steps during the ADL training in a hostpital or rehabilitation setting.

Many children with physical disability have feeding difficulties. In cases of children with cerebral palsy, feeding difficulties can be seen in abnormal oral motor activity and defective swallowing coo rdination. These problems originate from neurological lesions. The purpose of this study was to i nvestigate the effect of trunk and neck position on the following aspects of swallowing: stages of oral preparation, pharyngeal swallowing reflex, pharyngeal clearing and aspiration. Sixteen subjects with quadriplegic cerebral palsy were examined to assess their swal-lowing abil ity using videofluoroscopy(VFS). Subjects were evaluated in four different positions 1) trunk erect with the neck flexed 30°2) trunk reclined 30°posteriorly with the eck positioned neutrally 3) trunk re clined 30°posteriorly with the neck flexed 30° 4) trunk in supine with the neck flexed 30°. Friedman's test was used to analyze the effect of posi tion of the neck and trunk on swallowing. The results were as follows: 1. Ability of oral preparation was significantly better with the subject's trunk recli-ned 30°poste riorly and the neck flexed 30°than with the trunk erect and the neck flexed 30°(p < 0.05). 2. Ability of pharyngeal clearing was significantly better with the subject's trunk er-ect and the neck flexed 30° than in supine with the neck flexed 30°(p < 0.05). 3. Incidence of swallowing reflex was not significantly different among the four posi- tions (p > 0.05). 4. Prevention of aspiration was significantly better with the subject's trunk reclined 30°posteriorl y and the neck flexed 30° than with the trunk reclined 30°posteriorly and the neck neutrally positi oned or in supine with the neck flexed 30°(p < 0.05). These results suggest that positions of both the neck and the trunk have an effect on swallowi ng in children with cerebral palsy. The position with the trunk reclined 30°posteriorly and the n eck flexed 30°was found to be optimal for oral preparation and prevention of aspiration. Further r esearch to study swallowing ability in conjunc- tion with respiratory function is indicated.
