OBJECTIVE: To investigate the factors influencing the quiet standing balance of patients with incomplete cervical spinal cord injuries. Also to find the correlations between posturographic parameters and clinical balance tests as well as to find the correlation between posturographic parameters and functional independence. METHOD: We conducted a tetra-ataxiometric posturography, lower extremity motor score (LEMS), Korean version of the Berg Balance Scale (K-BBS), Timed Up and Go test (TUG), and Korean Version of the Modified Barthel Index (K-MBI) of 10 patients. 10 healthy adults carried out the posturography. We checked stability, weight distribution, Fourier and synchronization indices of eight positions, and the fall index of the posturography. RESULTS: The patient group showed significantly higher stability and weight distribution indices in all eight positions. Stability indices significantly increased with eyes closed or standing on pillows. Weight distribution indices were significantly higher with eyes closed or the head bent backwards. The patient group showed significantly higher Fourier indices of low, low-medium, and high frequency in eight positions. The Fourier indices at high-medium frequency were significantly higher with eyes closed on pillows or in variable head positions. There were no significant differences of synchronization indices between the patient and the control group. The falling index of the patient group significantly correlated with K-BBS, TUG, and K-MBI. LEMS had significant correlation with some synchronization indices, but not with the falling index. CONCLUSION: The quiet standing balance of the patients was influenced by somatosensory limitations or insufficient visual compensation. We should try to improve the postural balance and functional independence of patients through proper proprioceptive and lower extremity strength training for better postural and pedal control, and to make efforts to minimize environmental hazards.

OBJECTIVE: To investigate the feasibility and effects of balance training with a newly developed Balance Control Trainer (BCT) that applied the concept of vertical movement for the improvements of mobility and balance in chronic stroke patients. METHOD: Forty chronic stroke patients were randomly assigned to an experimental or a control group. The experimental group (n=20) underwent training with a BCT for 20 minutes a day, 5 days a week for 4 weeks, in addition to concurrent conventional physical therapy. The control group (n=20) underwent only conventional therapy for 4 weeks. All participants were assessed by: the Functional Ambulation Categories (FAC), 10-meter Walking Test (10mWT), Timed Up and Go test (TUG), Berg Balance Scale (BBS), Korean Modified Barthel Index (MBI), and Manual Muscle Test (MMT) before training, and at 2 and 4 weeks of training. RESULTS: There were statistically significant improvements in all parameters except knee extensor power at 2 weeks of treatment, and in all parameters except MBI which showed further statistically significant progress in the experimental group over the next two weeks (p<0.05). Statistically significant improvements on all measurements were observed in the experimental group after 4 weeks total. Comparing the two groups at 2 and 4 weeks of training respectively, 10mWT, TUG, and BBS showed statistically more significant improvements in the experimental group (p<0.05). CONCLUSION: Balance training with a newly developed BCT is feasible and may be an effective tool to improve balance and gait in ambulatory chronic stroke patients. Furthermore, it may provide additional benefits when used in conjunction with conventional therapies.

OBJECTIVE: To examine the effects of a bedside exercise program on the recovery of swallowing after a stroke. METHOD: Fifty stroke patients with dysphagia (<6 months post-stroke) were enrolled and classified into two groups, the experimental (25 subjects) and control groups (25 subjects). The control group was treated with conventional swallowing therapy. The experimental group received additional bedside exercise training, which consisted of oral, pharyngeal, laryngeal, and respiratory exercises, 1 hour per day for 2 months, and they were instructed regarding this program through the nursing intervention. All patients were assessed for their swallowing function by Videofluoroscopic Swallowing Study (VFSS), using the New VFSS scale, the level of functional oral intake, the frequency of dysphagia complications, the presence (or not) of tube feeding, the mood state and quality of life before the treatment and at 2 months after the treatment. RESULTS: After 2 months of treatment, the experimental group showed a significant improvement in the swallowing function at the oral phase in the New VFSS Scale than that of the control group (p<0.05). Further, they also showed less depressive mood and better quality of life than the control group. However, there was no significant change in the incidence of dysphagia complication and the presence (or not) of tube feeding between the two groups. CONCLUSION: Bedside exercise program showed an improvement of swallowing function and exhibited a positive secondary effect, such as mood state and quality of life, on subacute stroke patients with dysphagia. For improvement of rehabilitation results on subacute stroke patients with dysphagia, this study suggests that additional intensive bedside exercise would be necessary.

OBJECTIVE: To examine whether the pattern of brain activation induced by a motor task and the motor responses to transcranial magnetic stimulation (TMS) have prognostic implications for motor recovery after stroke. METHOD: Ten patients with first-ever subcortical stroke (55.7+/-17.3 years, 5 ischemic and 5 hemorrhagic) underwent 2 FDG PET studies under different conditions (1: rest, 2: activation with a specific motor task) at 37.7+/-25.2 days after stroke. The regions showing more than a 10% increase in glucose metabolism on subtraction images during activation and rest were considered to be significantly activated. Cortical excitability of intracortical inhibition (ICI) and intracortical facilitation (ICF) were assessed using the TMS from both abductor pollicis brevis muscles within 7 days of PET scans. Recovery of motor function was assessed at the point of the neurological plateau. RESULTS: The presence of a motor response at the plegic site to TMS and normal intracortical inhibition, and facilitation patterns in the unaffected hemisphere were found to be related to good recovery. An association between an ipsilesional activation on PET and good motor recovery was also observed, but this was significantly weaker than that between TMS measured cortical excitability and motor recovery. CONCLUSION: Integrity of the ipsilesional corticospinal pathway, normalized contralesional intracortical excitability, and task-related activation in the ipsilesional hemisphere were found to predict post-stroke motor recovery significantly.

OBJECTIVE: To describe an ultrasonography-guided technique for cubital tunnel injection. METHOD: The ulnar nerves from 12 elbows of 6 adult cadavers were scanned, and the cross-sectional areas of the ulnar nerves, cubital tunnel inlets and outlets were measured by using ultrasonography. All elbows were dissected after an ultrasonography-guided dye injection at the inlet of the cubital tunnel. The dissectors evaluated the spread of dye and the coloration of the nerve and remeasured the cross-sectional areas of the cubital tunnel inlets and outlets. RESULTS: After a real-time visualization of an ultrasonography-guided injection, the ulnar nerves were seperated from the medial groove for the ulnar nerve. All the ulnar nerves of the cadavers were successfully colored with the dye, from the inlet to oulet of the cubital tunnel. The post-injection cross-sectional areas were significantly larger than the pre-injection cross-sectional areas. No significant differences were detected in the post-injection cross-sectional areas of the cubital tunnel outlet and the ulnar nerve as compared with the pre-injection areas. CONCLUSION: Clinicians should consider real-time visualization of ultrasonography for guided injection around the ulnar nerve at the inlet of the cubital tunnel.

OBJECTIVE: To assess the intrarater and interrater reliability of the supraspinatus thickness measured by ultrasonography (US) in normal subjects and to identify the relationship between the supraspinatus thickness measured by US and cross sectional area (CSA) of the supraspinatus muscle by magnetic resonance imaging (MRI) in hemiplegic patients. METHOD: We examined 20 shoulders of normal subjects and 10 shoulders of hemiplegic patients. In normal subjects, one examiner measured the supraspinatus thickness twice by US at the scapular notch and another examiner measured the supraspinatus thickness several days later. The intrarater and interrater reliability of supraspinatus thickness measurements were then evaluated. In hemiplegic patients, the supraspinatus thickness at the scapular notch was measured by US in affected side and compared with CSA of the supraspinatus muscle at the scapular notch and the Y-view of MRI. RESULTS: One examiner's supraspinatus thickness measurement average was 1.72+/-0.21 cm and 1.74+/-0.24 cm, and the other examiner's supraspinatus thickness measurement average was 1.74+/-0.22 cm in normal subjects. Intraclass correlation coefficients of intrarater and interrater examination were 0.91 and 0.88, respectively. For hemiplegic patients, the supraspinatus thickness measured by US was 1.66+/-0.13 cm and CSA by MRI was 4.83+/-0.88 cm2 at the Y-view and 5.61+/-1.19 cm2 at the scapular notch. The Pearson Correlation Coefficient between the supraspinatus thickness at the scapular notch and the CSA at the Y-view was 0.72 and that between the supraspinatus thickness and CSA at the scapular notch was 0.76. CONCLUSION: The supraspinatus thickness measurement by US is a reliable method and is positively correlated with the CSA of the supraspinatus muscle in MRI in hemiplegic patients. Therefore, supraspinatus thickness measurement by US can be used in the evaluation of muscle atrophy and to determine therapeutic effects in hemiplegic patients.

OBJECTIVE: To identify the volumes of contrast material needed to reach the specific landmarks and contrast pattern during Kambin's triangle approach (KB-A) in lumbar spinal stenosis. METHOD: Sixty patients undergoing KB-A were investigated. Fifty-six patients were included in this study. KB-A were performed with the use of contrast-enhanced fluoroscopic visualization. After confirming the appropriate spinal needle position, a slow injection of up to 5.0 ml of nonionic contrast material was carried out. Under intermittent fluoroscopic guidance, contrast volumes were recorded as flow reached specific anatomic landmarks: ipsilateral inferior or superior neural foramen. RESULTS: After 2.0 ml of contrast was injected, 93.2% of KB-A cases spread to the medial aspect of the inferior pedicle of the corresponding level of injection and 86.3% of KB-A spread to the medial aspect of the superior pedicle of the corresponding level of injection. After 3 ml of contrast was injected, 95.3% of KB-A spread to cover both the medial aspect of the inferior pedicle and the superior pedicle of the corresponding level of injection. A volume of 2 ml of injectate reaches the anterior epidural space 100% of the time. CONCLUSION: This study demonstrates injectate volumes needed to reach the specific anatomic landmarks in KB-A. A volume of 3.0 ml of injectate reaches both the medial aspect of theinferior pedicle and the superior pedicle 94.6% of the time. Therefore, Interventionalists may consider a 1-level instead of a 2-level injection for patients with a bleeding risk or for 2 level central pathology.

OBJECTIVE: To observe the contrast spreading patterns in the retrodiscal (RD) approach for transforaminal epidural steroid injections and their effect on pain reduction. METHOD: Patients with L5 radiculopathy who were scheduled to receive lumbar TF-EPB were consecutively included. We randomly divided them into the L4-5 RD and L5-S1 RD groups and administered 1 cc of contrast dye into epidural space. We observed the shape and the location of contrast dye on the anterior-posterior and lateral views. We injected 1 cc of 0.5% lidocaine mixed with 20 mg of triamcinolone, and checked the pain intensity before and two weeks after the procedure by using visual analogue scale (VAS). RESULTS: In the L4-5 RD group (n=30), contrast spread over the L4 nerve root in 27 cases and the L4 and L5 nerve roots in 3 cases. In the L5-S1 RD group (n=33), contrast spread over the L5 nerve root in 20 cases, the S1 nerve root in 3 cases, and the L5 and the S1 nerve roots in 10 cases. The contrast spreading patterns could be divided into 4 patterns: the proximal root in 40 cases, the distal root in 19 cases, the anterior epidural space in 3 cases and an undefined pattern in 1 case. CONCLUSION: In RD lumbar TF-EPB, the contrast dye mostly went into the cephalic root and about 60% spread over the proximal nerve root. There was less pain reduction when the contrast dye spread over the distal nerve root.

OBJECTIVE: To evaluate the effect of hyaluronidase in patients with failed back surgery syndrome (FBSS) treated with interlaminar lumbar epidural injection (ILEI). METHOD: Sixty patients suffering from severe low back pain and sciatica were randomly allocated into three groups. Group T received ILEI with 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. Group H received ILEI with 1500 IU hyaluronidase and 5 ml bupivacaine 0.25%. Group TH received interlaminar lumbar epidural injection (ILEI) with 1500 IU hyaluronidase, 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. The effect was evaluated using Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) at pre-injection, 2 weeks, 6 weeks and 12 weeks after ILEI. RESULTS: After 2 weeks and after 6 weeks, patients in both Group T and Group TH had significant effectiveness more than Group H in decrease of VAS and ODI. After 12 weeks, only patients in Group TH had significant effectiveness in decrease of VAS and ODI (p<0.05). In every period, Group TH had the most effectivess in decrease of VAS and ODI after ILEI. CONCLUSION: ILEI for FBSS with triamcinolone and hyaluronidase is considered to have more long term effectiveness to reduce pain and improve function after ILEI than injection with triamcinolone alone or hyaluronidase alone.

OBJECTIVE: To investigate whether the cartilage regenerative effects of intra-aricular platelet-rich plasma (PRP) are different, according to the severity of osteoarthritis (OA), in a collagenase-induced knee OA rabbit model. METHOD: New Zealand white rabbits (N=21) were randomly divided into three groups. Three different doses (0.25 mg, group 1; 0.5 mg, group 2; and 1.0 mg, group 3) of collagenase were injected twice into both knees of each group under an ultrasound guidance. The mean platelet concentration of the PRP fraction was 2,664+/-970x10(3)/microl and was enriched 8.2-times, compared with the whole blood. PRP (0.3 ml) was injected into the left knee and saline (0.3 ml) into the right knee at 4 weeks, and macroscopic and histological scores of both injected knees were evaluated at 9 weeks after the first collagenase injection. RESULTS: Macroscopic and histological scores of group 3 were significantly higher than those of group 1 and 2 (p<0.05). Macroscopic and histological scores of the PRP-injected knees were significantly lower than those of the saline-injected knees, in all groups (p<0.05). Differences of gross morphologic and histologic scores between saline- and PRP-injected knees in group 3 were significantly higher than those in group 1 and 2 (p<0.05). CONCLUSION: Intra-articular PRP injection influences cartilage regeneration in all severities of rabbit knee OA, and the cartilage regenerative power of PRP injection in moderate knee OA was greater than that in mild or very mild OA. A large preclinical trial is needed to establish the validity of our study.
