Effect of Computerized Neuropsychologic Test in Subacute Post-Stroke Patient With Cognitive Impairment / 고신대학교의과대학학술지

OBJECTIVES: To investigate the effects of Computerized Neuropsychologic Test (CNT) on cognitive function and daily life performance in subacute post-stroke patients with cognitive impairment. METHODS: Korean Mini-Mentals State Examination (K-MMSE), Korean version of Modified Barthel Index (K-MBI) were investigated in 125 subacute post-stroke patients with cognitive impairment. We analyzed K-MMSE and K-MBI which were conducted 63 patients who had received CNT and 62 patient who had not received CNT from baseline to 8 weeks follow-up. In the experimental group, initial K-MMSE and K-MBI were conducted 13.3 ± 6.8 weeks after the onset of stroke and their age was 63.4 ± 13.3. In the control group, initial K-MMSE and K-MBI were conducted 13.2 ± 7.7 weeks after the onset of stroke and their age was 65.1 ± 11.6. RESULTS: The 8 weeks follow-up total K-MMSE score and total K-MBI score of experimental group were significantly higher than control group (P 0.05). In K-MMSE subsection, change of orientation, registration, language and visual reconstruction were correlated with total K-MBI s core after CNT. Especially, the experimental group, total K-MBI score of the left hemisphere damage group was significantly higher than the right hemisphere damage group (P < 0.05). CONCLUSIONS: This study shows that CNT is effective on subacute post-stroke patients with cognitive impairment. Improvement of cognitive function can expect a positive outcome on daily life performance, in particular, it can be expected to improve the prognosis of patients with stroke, the left hemisphere lesions.

Tracheo-Innominate Artery Fistula after Stroke

Tracheo-innominate artery fistula (TIAF) is rare, yet the most fatal complication after tracheostomy. In the absence of immediate diagnosis and surgical management, the mortality rate is very high, because the complication can lead to sudden massive tracheal hemorrhage. Tracheal obstruction and hypovolemic shock are the major life threatening conditions. The 46-year-old woman received tracheostomy tube insertion after stroke. Three months later, there was occurrence of active bleeding at the site of tracheostomy in the patient, who participated in comprehensive rehabilitation program. Immediately, the patient received an endotracheal tube insertion into the tracheostomy site and thus massive bleeding was controlled. The patient was transferred to the intensive care unit, where her breathing was maintained by mechanical ventilation. Based on computed tomography and laryngoscopy, no remarkable findings about TIAF were detected. Nevertheless, transfemoral angiography findings revealed that innominate artery made small luminal outpouching to trachea at the carotid artery and at the subclavian artery bifurcation level, based on which a diagnosis of TIAF was made. She had an operation for TIAF, tracheoplasty with bypass graft. Subsequently, she was discharged after 15 weeks. In the present report, we describe a case of TIAF, which can occur in the patients with tracheostomy tube during rehabilitation.

Leisure Time Physical Activity of People with Spinal Cord Injury: Mainly with Clubs of Spinal Cord Injury Patients in Busan-Kyeongnam, Korea

OBJECTIVE: To estimate hours of leisure time physical activity (LTPA) performed by people with chronic spinal cord injury (SCI) and to identify the demographic and injury-related characteristics associated with LTPA of people with chronic SCI. METHOD: Seventy nine persons with SCI living in Busan and Gyongsangnam-do were recruited. They completed a self-administered questionnaire, which consisted of items about personal characteristics, type of LTPA, hours of LTPA, LTPA intensity, and LTPA satisfaction. RESULTS: Most participants (92.4%) did not work. The respondents reported a daily mean of 3.13 hours (+/-1.47) of LTPA; however, 3.8% reported no LTPA whatsoever. Years post-injury, income sources, and type of medical payment emerged as a predictors of LTPA. Years post-injury were positively correlated with amount of leisure activity. In the case of self income, LTPA was longer than for groups with different income sources (e.g.partner, parents). For patients receiving workers' compensation insurance, LTPA was longer than for patients receiving non-WC insurance. Most LTPA was done at a moderate intensity. The three most frequently reported types of LTPA were wheeling (26%), sports (19%), and stretching exercise (15%). There was overall dissatisfaction with LTPA. CONCLUSION: Daily LTPA hours were longer than previously reported, but wheeling accounted for a large part of the activity. Intensity of activity was generally moderate. The employment rate was very low. Clearly, participating in regular LTPA for health purposes is very important to people with chronic SCI, but it is also important for them to have jobs.

The Effect of Strapping on Hemiplegic Shoulder Subluxation: A Pilot Study

OBJECTIVE: To investigate the effect of taping therapy on hemiplegic shoulder subluxation. METHOD: Sixty patients were randomly assigned to three groups. In study group, two parts of the first tape was shaped as letter Y and were attached from humeral insertion of deltoid muscle to extension line of the clavicle midline, following anterior and middle deltoid line, respectively, with 125% elasticity. And two parts of the second tape as same as the first tape were attached horizontally from head of greater tubercle to medial border of scapular, following supraspinatus and infraspinatus muscles, respectively, with 125% elasticity. The placebo group was applied by the tape with 100% and 150% elasticity and control group was not applied. The effects of strapping were evaluated by using visual analogue scale (VAS), passive range of movement (ROM), vertical distance (VD) and horizontal distance (HD) on radiologic findings of plain anteroposterior (AP) view and lateral distance (LD) on shoulder ultrasonography at entry (day 0), 1 and 2 days later. RESULTS: Repeated measured analysis of variances indicated that the study group showed corrective effect in the VAS (p<0.05). The control and placebo groups showed no significant change in any parameters of distance measurements and clinical findings. In every group, spasticity, MMT and Brunnstrom stage were not changed during study. CONCLUSION: The taping therapy with 125% elasticity may be helpful for patients with hemiplegic shoulder to reduce pain.

Electrophysiological Characteristics of Autonomic Nervous System Function in Post-Stroke Patients

OBJECTIVE: To evaluate the autonomic nervous function in post-stroke patients. METHOD: A total of 58 subjects, 34 post-stroke patients (mean age of 61.35 years) and 24 healthy subjects (mean age of 34.42 years) were included. The sympathetic skin response (SSR), the R-R interval variation (RRIV) and orthostatic hypotension (OH) were evaluated. Bilateral sympathetic skin responses were recorded on the palm and sole with stimulation of both median and tibial nerves. The obtained SSRs were divided into normal response and abnormal response including no response. The R-R interval variations were estimated during rest, deep breathing and Valsalva maneuver respectively. RESULTS: In all healthy subjects, obtained SSRs were of normal response. Although the rate of abnormal SSR was 75.4% (205 of 272 waves) in stroke patients, the rate of abnormal SSR on affected side (81.6%, 111 of 136 waves) was significantly higher than unaffected side (69.1%, 94 of 136 waves) (p0.05). The RRIV of stroke patients with OH (1.09+/-0.06) was significantly lower than in control (1.14+/-0.05) during rest (p<0.01), and in stroke patients without OH, the RRIV (1.13+/-0.06) was also significantly lower than in control (1.27+/-0.22) during Valsalva maneuver (p<0.01). CONCLUSION: Evaluation of SSR and RRIV could be helpful in detecting dysfunction of autonomic nervous system in post-stroke patients.

Magnetic Resonance Arthrographic Findings of the Painful Hemiplegic Shoulder

OBJECTIVE: To identify the etiology of hemiplegic shoulder pain by magnetic resonance (MR) arthrography. METHOD: The study included seventy-four hemiplegic patients with shoulder pain. After several physical examinations, all patients had fluoroscopically guided injection by a physiatrist with a maximum of 12~15 ml of contrast agent. Then T1-weighted, T2-weighted and fat-suppressed T1-weighted images were taken at the oblique coronal plane. In addition, fat-suppressed T1-weighted images were obtained at the oblique sagittal and oblique coronal plane. RESULTS: Except for the 9 patients who did not finish the study, the mean age of the participants was 61.5+/-8.9 years and mean duration of the cerebrovascular accident (CVA) was 15.7+/-9.7 weeks. The findings were as follows: 40% supraspinatus tendinitis, 30.8% superior labrum anterior to posterior (SLAP) lesion, 29.2% adhesive capsulitis, 24.6% supraspinatus partial tear, 23.1% biceps tendinitis, 13.8% supraspinatus full thickness tear, 7.7% infraspinatus partial tear. The SLAP lesion had significant statistic relationship with biceps tendinitis (p<0.05) but not with rotator cuff lesion. CONCLUSION: We found that causes of hemiplegic shoulder pain were various. The prevalence of the SLAP lesion was high (30.8%). We recommend the MR arthrography when the hemiplegic shoulder pain does not improve by conventional therapy or the cause of the pain is uncertain.

Comparison of Activity Patterns between Rehabilitation Stroke Unit and Mixed Rehabilitation Ward for Stroke Patients

OBJECTIVE: To determine if the physical design and organizational structure of rehabilitation stroke unit (RSU) is related to the amount of patients' activity pattern. METHOD: An observational study was conducted using behavioral mapping method. Time samples of the motor activity of patients following stroke were taken at 10-minute interval, between 7 AM and 7 PM both on weekdays and weekends. At each observation, physical activity patterns, location in which the patients spent their time, and other person present were recorded. RESULTS: RSU patient spent less time in non-therapeutic activity and more time in therapeutic activity (p<0.05). There were significant differences in the locations of patient's position between the two types of ward (p<0.05). RSU patients had significantly more interaction with formal carerand less time disengaged (p<0.05). The proportion of time in therapeutic activity was low in all location, with patients spending many hours in bed and doing nothing. There was no significant differences in total Functional Independence Measure (FIM) scores at admission and on discharge, FIM gain, and FIM efficiency between RSU and mixed rehabilitation ward (p<0.05). CONCLUSION: In spite of quantitative difference, the two wards had similar patterns of treatment activity and deployment of staff. These maybe resulted in similar treatment experiences for patient and no functional differences between two wards. It appears that strategies are required so that patients can be practicing at an more appropriate level.

Long-term Follow-up of Idiopathic Facial Palsy

OBJECTIVE: The purpose of this study was to observe clinical characteristics and electrodiagnostic findings of idiopathic facial palsy and to follow up beyond 1 year after onset. METHOD: From February 2002 to July 2003 the authors analyzed 103 cases that could be followed up after 1 year since diagnosed as idiopathic facial palsy by electrodiagnostic study which was performed at approximately 2 weeks after the onset time. The patients were classified by House- Brackmann (H-B) facial nerve grading system on their first visits and followed up by telephone interview using H-B system. Treatment method, age, sex, medical history and symptoms were noted. In addition, the blink reflex, nerve conduction study and needle electromyography (EMG) were done. RESULTS: When degree of degeneration (% degeneration) was greater than 90% at approximately 2 weeks after the onset or motor unit action potentials were not detected in at least one among the four tested muscles, patients did not gain satisfactory facial function after 1 year. CONCLUSION: Methods related to prognosis of idiopathic facial palsy were compared with side to side evoked potential amplitude and needle EMG. This methods would be helpful to explain its prognosis.

Chronic Progressive Radiation Myelopathy Associated with Radiation Therapy: A case report

Chronic progressive radiation myelopathy(CPRM) is a rare but serious complication of radiation therapy. It's exact cause is unknown and the diagnosis is usually made based on the exclusion of other causes of myelopathy. Magnetic resonance imaging(MRI) with gadolinium- diethylenetriamine pentaacetic acid(DTPA) enhancement seems to be useful for the diagnosis of CPRM. There is no known effective treatment and the complication is irreversible. We report a case of CPRM after radiation therapy for subglottic cancer which was not respond to high-dose steroid therapy with review of literature.
