Objective
The intrarectal pressure can make error during urodynamic study and can decrease the accuracy of detrusor pressures. The purpose of this study was to investigate the incidence and cause of the error in measurement of recral pressure. Method: Forty-eight patients with spinal cord injury were enrolled. With the patients in the lithotomy position, catheter was placed into the bladder and the rectum, then urodynamic testing began by infusion of normal saline (20∼30^oC) via urethral catheter. The errors by measurement of rectal pressure during urodynamic study were recorded. According to the position of patients and spasticity of hipflexors, difference of rectal pressure was investigated. Results: The error rate of intrarectal pressure during urodynamic study was 41%. Intrarectal pressure was higher in lithotomy position than in lateral lying position. According to modified Ashworth scale of hip flexors, intrarectal pressure in grade 0 was significantly lower than grade 1, 1.5 and 2 (p＜0.05). Conclusion: There was significant errors in measuring of the intravesical pressure during urodynamic study. These factors might be posture, spasticity of hip flexors, and expelling of the catheter in urodynamic study. (J Korean Acad Rehab Med 2006; 30: 571-574)

Objective: To evaluate the usefulness of a newly devised portable cystometer to measure the pressure of bladder in a low cost and easier accessability.

Method: This study was performed in 47 patients with a conventional instrumental cystometer (Jupiter 8000, Wiest) and the newly devised portable cystometer. In the supine position, we measured the maximal intravesical pressure, abdominal pressure and bladder volume with the portable cystometer just after the measurement of the maximal detrusor pressure and bladder volume with the conventional instrumental cystometer. Paired t-test was utilized to analyze and compare the result.

Results: 1) There was no significant difference in the average maximal detrusor pressures measured by maximal intravesical pressures minus abdominal pressures, which were 38.32⁑20.97 cmH₂O by the conventional instrumental cystometer and 40.02⁑20.70 cmH₂O by the portable cystometer (p＞0.05). 2) There was no significant difference in the average bladder volumes at maximal detrusor pressure, which were 302.13⁑83.92 cc by the conventional instrumental cystometer and 314.04⁑94.17 cc by the portable cystometer (p＞0.05).

Conclusion: We conclude that there is no significant difference between the conventional instrumental cystometer and the portable cystometer in the measurement of detrusor pressure and bladder volume. We believe this portable cystometer would be a useful tool to evaluate the function of bladder in a low cost and easier accessability.

Objective: The purpose of this study is to evaluate the effects of regular sports activity on psychosocial adaptation, natural killer cell activity (NKCA) as an immunologic measure and HDL-cholesterol level as an indirect index of heart disease in chronic spinal cord injured persons.

Method: We compared two groups. One is sports group (n=13) who has been doing regular sports activity more than three hours a week for at least one year. Another group who leads sedentary life matched age and body mass index served as a control group (n=13). For the evaluation of psychosocial adaptation, we assessed Rosenberg Self Esteem Scale as subjective measure, Craig Handicap Assessment and Reporting Technique (CHART) as objective measure and Symptom Checklist 90 Revision (SCL-90-R) as a psychologic evaluation. NKCA and serum HDL-cholesterol level were assessed.

Results: There was no significant difference in subjective measure and psychologic evaluation between two groups. CHART score and NKCA are significantly higher in the sports group than in the control group (p＜0.05). HDL cholesterol level was increased in the sports group compared with the control group.

Conclusion: Participating in regular sports activity improved the psychosocial adaptation and immune system in chronic spinal cord injured persons.
