[The relationship between functional recovery one year after a stroke, and related factors].

This study examines the factors affecting functional performance of 40 hemiplegic subjects in their homes following discharge from the hospital. All subjects suffered a cerebral vascular accident at least one year prior to this research period. Barthel Index was used to assess subjects' self-reported functional level in activities of daily living (ADL). A backward elimination of stepwise regression analysis was performed to ascertain the predictive value of the variables in determining functional performance one year after the onset of a stroke. These variables are factors related to the initial onset and those affecting the patient's functional status at home. The results revealed that subjects who had a shorter length of stay in the hospital, scored a higher on the Barthel Index (p less than 0.05). It also demonstrated that subjects who were more satisfied with their current subjective health status, had a higher Barthel Index score.

[The relationship between early motor stage and hand function recovery six months after stroke].

The prognosis of hemiplegic hand function may reflect intrinsic recovery. Applying the variables of initial neurological loss in the hemiplegic upper extremity to predict the prognosis of hand function will enable therapists to establish the ultimate goals of rehabilitation and to select the appropriate treatment programs. Pinch and grip strength tests, Frenchay arm function test and the nine-hole peg test were used to determine the relationship between the initial Brunnstrom motor stage of the hemiplegic upper extremity and the prognosis of hand function after six months. Forty stroke patients were divided into three groups. Group I was subjects with a motor stage below the Brunnstrom motor stage III in both proximal and distal parts of the hemiplegic upper extremity. Group II was subjects with motor stage below Brunnstrom motor stage III in the proximal part and above stage III in the distal part or vice versa. Group III was subjects with a motor stage above Brunnstrom motor stage III both in the proximal and the distal parts. The results of this study indicated that the prognosis of the Brunnstrom motor stage of the hemiplegic upper extremity generally improved about one or two stages. According to the results of the grip and pinch strength tests, the Frenchay arm function test or the nine-hole peg test, group I patients could hardly use their affected hand functionally. The grip strength and the pinch strength deficits of group I were 93.8% and 91.4% respectively. The grip strength and the pinch strength deficits of group II were 72.1% and 68.5% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

[Application and evaluation of the VICON system in gait analysis].

By employing the VICON system, segment angular displacement, velocity and acceleration of the lower limbs were achieved from an Above-Knee (A/K) Amputee using a constant friction prosthesis during the swing phase of the gait cycle. By applying computer for data analysis and inputing anthropometric data of the (A/K) Amputee, kinematic trajectory and a stick diagram of lower limbs were obtained. The data were then compared with those obtained from normal subjects. The results showed that the VICON system can provide quantitative analysis of several important parameters in the gait cycle and that it is very helpful in the evaluation and rehabilitation training of abnormal gait.
