Objective: To determine the comprehensive hand repetitive inten- sive strengthening training (CHRIST)-induced morphologic changes in the commonly affected extensor carpi radialis (ECR) and triceps brachii muscle and associated muscle strength and motor performance in a child with spastic quadriplegic cerebral palsy (CP) using stan- dardized clinical tests and ultrasound imaging. Design: A single-case study with pre- and posttest. Setting: Pediatric physical therapy de- partment at a city hospital. Participant: The patient was a 10-year-old girl who was diagnosed with spastic quadriplegic CP. Interventions: The child was trained with CHRIST for 60 minutes a day, 5 times a week, for 5 weeks. The CHRIST was designed to improve motor function and strength of the upper-extremity muscles. Main Outcome Measures: Clinical tests, including the modified Wolf Motor Function Test, Jebsen-Taylor Hand Function Test, and Pediatric Motor Activity Log questionnaire, were used to compare the intervention-related changes in motor performance. Results: Ultrasound imaging data showed that the cross-sectional areas of both the ECR and triceps brachii muscles at relaxation and contraction states were enhanced and the therapy-induced muscle structural changes were associated with enhanced muscle strength and motor performance. Our results suggest that the CHRIST was effective in treating muscle weakness and associated motor dysfunction in a child with spastic quadriplegic CP. Conclusions: As a first step in developing an innovative and effective neurorehabilitation technique, our findings demonstrated the efficacy of CHRIST for improving muscle structure and strength as well as motor performance and skills in a child with quadriplegic CP.

Poster 60 The Validity and Reliability of the Motor Point Detection System: A Preliminary Investigation of Motor Points of the Triceps Surae Muscles. Nam Lee (Yonsei University, Wonju City, Korea), Joshua You, Ho Park, Hyoun Myoung. Disclosure: None declared. Objective: To investigate the validity and reliability of the motor point detection (MPD) system in cadavers and healthy young adults. Design: Correlation statistics. Setting: University research laboratory. Participants: 62 lower limbs of the 31 healthy young adults (mean age, 22.31.8y) and 10 size-matched lower limbs from cadavers were used. Interventions: Not applicable. Main Outcome Measures: The validity of the MPD system’s motor point measure was determined by comparing the motor point locations of the lower-leg muscles obtained from the MPD system with the established anatomic motor point locations from our previous cadaveric dissection study. The anatomic motor points were determined by tracing the terminal motor nerve branches on the soleus and the medial and lateral gastrocnemius muscles through dissection of adult cadavers. The test-retest reliability was determined by repeatedly measuring the locations of the motor point in healthy young adults on 2 separate occasions, approximately 24 hours apart. The intraclass correlation coefficient (ICC) was com- puted to determine correlation and the independent t test was used to determine the difference between the demographic and clinical vari- ables at significance level (P.05). Results: Correlation analysis revealed relatively high validity between the MPD system and cadaver- dissected motor point location measurements (ICC 2,1 range, .71-.92; P.05). The test-retest reliability showed excellent correlation be- tween the repeated measures, with an ICC 2,1 ranging from .90 to .95 (P.05). Conclusions: Our results demonstrated that the MPD system is accurate and consistent in measurement of motor point locations of the lower-leg muscles. This system can be considered as an alternative device to localize motor points in clinical settings. Our MPD system warrants further investigation in pathologic population.

James Krause (Medical University of South Carolina, Charleston, SC), John McArdle, Jennifer Coker. Disclosure: None declared. Objective: To identify changes in depressive symptoms using the Patient Health Questionnaire-9 (PHQ-9) in persons with spinal cord injury between inpatient rehabilitation and 1-year postdischarge. De- sign: Interview and survey. Setting: A large rehabilitation hospital in the southeastern United States. Participants: 568 adults completed materials while hospitalized an average of 50.2 days after onset. A subset of these participants was contacted at 1 year postdischarge, with 219 completing a follow-up measure. Interventions: Not applicable. Main Outcome Measures: PHQ-9, a screening measure of major depressive disorders. SPSS was used to calculate the change in portion of participants at extreme ends of the depressive symptom continuum, and Mplus was used to perform cross-lag regression between the 2 times of measurement for somatic and nonsomatic factors (identified using confirmatory factor analysis at baseline). Results: A signifi- cantly greater portion of subjects were at extremes at 1-year follow-up (27%) compared with inpatient rehabilitation (17%). The nonsomatic factor (ie, all except fatigue, appetite, sleep) from inpatient stay was significantly predictive of the nonsomatic (r=.35, P.001) and so- matic factor at follow-up (r=.40, P.001). In contrast, the somatic factor did not significantly predict the somatic (r=.13, P=not signif- icant [NS]) or nonsomatic factor at follow-up (r=.07, P=NS). The 2 factors were significantly correlated at follow-up (r=.32, P.001). Conclusions: Our results question the meaning of somatic items during inpatient rehabilitation because they are not predictive of either somatic or nonsomatic symptoms at follow-up. If the goal of inpatient assessment is to predict future outcomes, then nonsomatic items should be used in the prediction. Clinicians should also be aware that depressive symptoms during inpatient rehabilitation are unlikely to fall at either extreme, adding to the complexity of predicting depressive symptoms after discharge.

Disclosure: None declared. Objective: To determine whether persons with Parkinson disease (PD) who completed an 8-week, supervised Italian version of a pole- striding exercise program, had significant improvement in cognitive skills, activities of daily living, motor function, and quality of life (QOL). Design: Not provided. Setting: Not provided. Participants: 18 male volunteers (age, 72.73.7y). Interventions: Volunteers per- formed the Italian version of the pole-striding exercise program 3 times a week for 373min. Main Outcome Measures: The Unified Parkinson Disease Rating Scale (UPDRS) and Parkinson’s Disease Questionnaire (PDQ-39) were used to measure functional indepen- dence. Differences in pre- and posttraining scores on the UPDRS and PDQ-39 were analyzed using the Wilcoxon signed-rank test. Results: A statistically significant improvement occurred in the UPDRS (P.026) and PDQ-39 (P.028) scores after the moderate intensity exercise intervention. Conclusions: The results of this nonrandomized clinical trial indicate that an 8-week, individualized Italian pole-strid- ing exercise program increases perceived functional independence and QOL in persons with PD.
