Efficacy of Transforaminal Epidural Steroid Injections According to Nerve Root Enhancement

OBJECTIVE: To determine the efficacy of transforaminal epidural steroid injections according to nerve root enhancement in lumbar disc herniations. METHOD: Twenty seven patients who had extruded or seques tered lumbar disc herniations on enhanced MR imaging were investigated: fifteen patients with corresponding nerve root enhancement (enhanced group), and twelve patients without enhancement (non-enhanced group). All patients received transforaminal epidural steroid injection. Clinical outcomes were measured by visual analogue scale (VAS) for back and radicular pain, Oswestry disability index (ODI) before treatment and one month after injection. RESULTS: The averages of VAS for lower extremity and back pain in both groups one month after injection significantly reduced compared to that of pretreatment, respectively (p<0.001). The amount of decrease in pain in enhanced group was larger than that of non-enhanced group (p<0.05). The averages of ODI in both group one month after injection significantly reduced compared to that of pretreatment (p<0.0001), however, there was no difference between the two groups. CONCLUSION: The nerve root enhancement on contrast-enhanced MR imaging indicates the presence of severe inflammatory reaction of nerve root, which means well-responsiveness to anti-inflammatory treatment such as transforaminal epidural steroid injection, even if patients' symptom is very severe.

The Measurement of Force and Endurance during Wheelchair Propulsion in Paraplegics Using BTE Work Simulator

OBJECTIVE: To evaluate the force, endurance and influencing factors for wheelchair propulsion in paraplegics using BTE work simulator, and to find out a better method improving fitness levels for the paraplegics. METHOD: Seventeen paraplegic men were enrolled for the study. Isometirc and isotonic strength and dynamic endurance levels for wheelchair propulsion were measured using BTE work simulator. Neurological and demographical characteristics of patients were collected by personal interviews and direct examinations. RESULT: The spinal cord injured level showed a significant correlation with dynamic endurance (r=0.503, p<0.05) but not with the isometric and isotonic strength. The total duration of wheelchair use showed a significant correlation with the isotonic strength (r=0.497, p<0.05), but not with the isometric strength and dynamic endurance. The age and outdoor activities or exercise time during one week showed no significant correlation. CONCLUSION: Spinal cord injured level positively correlated with dynamic endurance. Both cardiorespiratory effect and trunk balance may influence this correlation. The total duration of wheelchair use wasn't correlate with dynamic endurnace. It seems to be more advisable trunk balance training goes with dynamic endurance training in rehabilitation program.

Quality of Life and Life Satisfaction of the Registered Disabled Persons in Uiwang City

OBJECTIVE: The purposes of this study were to investigate the factors influencing life satisfaction and quality of life (QOL) of the disabled persons and to help the planning and evaluation of Community Based Rehabilitation (CBR). METHOD: Data were collected through personal interviews of 503 registrated disabled persons in Uiwang City. Demographic variables and scores of modified Barthel index (MBI), modified Lambeth disability screening questionnaire (MLDSQ), Craig handicap assessment and reporting technique (CHART) and life domain satisfaction measure (LDSM) were obtained. RESULTS: The score of LDSM was 4.0+/-1.0. Life satisfaction was related to the age, sex, employment status, severity of disability, educational level, housing and residence, level of instrumental activities of daily living and social integration. MLDSQ score was the most strong predictor of life satisfaction (p=0.00) followed by social integration (p=0.001) and total CHART scores (p=0.017). And the factors influencing the handicap were monthly income, severity of disability, employment, level of education and age. CONCLUSION: Based on our study, we suggest that the CBR program of Uiwang City need to focus on improving functional ability and social skill of disabled individual and housing, and also promoting their vocational and educational status.

Suprascapular Nerve Injury Restricted to the Infraspinatus Muscle by a Ganglion Cyst: A case report

Suprascapular nerve injury restricted to the infraspinatus muscle is an uncommon condition. We present a 29 year-old man who complained of right shoulder pain and weakness for 8 months. Physical examination revealed atrophy of right infraspinatus muscle and T2 weighted MRI of the right shoulder revealed a mass with homogeneous high intensity at the spinoglenoid notch and atrophy of right infraspinatus muscle. EMG study revealed abnormal spontaneous activities and reduced recruitment pattern of motor units in right infraspinatus muscle. Symptoms improved after the excision of a mass which was a ganglion cyst by pathologic examination. We were reporting a case of suprascapular nerve injury restricted to the infraspinatus muscle.
