ObjectiveTo investigate the additive effect of sono-guided subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders.MethodThis prospective randomized controlled trial involved 26 patients who had shoulder pain. Group A, consisting of 13 patients, was treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml), followed by injection with sodium hyaluronate (2 ml) once a week for 3 weeks. The other 13 patients (Group B) were treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml) once a week for 3 weeks. The effects were assessed using a visual analogue scale (VAS) of shoulder pain, active range of motion (AROM), shoulder function assessment scale (SFA), shoulder disability questionnaire (SDQ) at study entry and every week from first injection until 4 weeks after the 1st injection (= 2 weeks after 3rd injection).Results(1) Demographic features and all parameters measured before injection did not show a significant difference between the 2 groups. (2) Statistically significant improvements were shown in VAS, SFA, SDQ during the 1st, 2nd, and 4th week after the first injection in both groups (p<0.05). (3) SFA showed significant improvement at 1 week after injection only in group A (p<0.05). (4) AROM of internal rotation showed significant improvement at week 4 after the 1st injection only in group A (p<0.05).ConclusionSubacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders has additive effects on functional improvement of the affected shoulder, including the AROM of internal rotation.
ObjectiveTo evaluate effects of subacromial bursa injection with steroid according to dosage and to investigate whether hyaluronidase can reduce steroid dosage.MethodsThirty patients with periarticular shoulder disorder were assigned to receive subacromial bursa injection once a week for two consecutive weeks. Ten patients (group A) underwent subacromial bursa injection with triamcinolone 20 mg; another group of ten patients (group B) with hyaluronidase 1,500 IU and triamcinolone 20 mg; and the other ten patients (group C) with triamcinolone 40 mg. We examined the active range of motion (AROM) of the shoulder joint, visual analogue scale (VAS), and shoulder disability questionnaire (SDQ) at study entry and every week until 1 week after the 2nd injection.ResultsAll groups showed statistically significant improvements in VAS after 1st and 2nd injections. When comparing the degree of improvement in VAS, there were statistically significant differences between groups C and A or B, but not between groups A and B. SDQ was statistically significantly improved only in groups B and C, as compared to pre-injection. There were statistically significant differences in improvement of SDQ after the 2nd injection between groups C and A or B. Statistically significant improvements in AROM were shown in abduction (groups B and C) and in flexion (group C only).ConclusionRepeated high-dose (40 mg) steroid injection was more effective in terms of pain relief and functional improvements of shoulder joint than medium-dose (20 mg) steroid injection in periarticular disorder. Hyaluronidase seems to have little additive effect on subacromial bursa injection for reducing the dosage of steroid.
ObjectiveTo investigate the effect of botulinum toxin type A (BTXA) on drooling and the morphologic change of the salivary gland in patients with cerebral palsy.MethodEight cerebral palsy patients suffering from severe drooling participated in this study. BTXA was injected into both submandibular and parotid glands under intravenous sedation and with ultrasound guidance (1 unit/gland/kg: maximum 100 units) in an outpatient or inpatient procedure. The severity of drooling was measured before injection and 3 weeks after injection using the Teacher Drooling Scale, the Drooling Score-severity, frequency and the Visual Analog Scale. To investigate the morphologic change of the salivary glands, the size of salivary glands were measured before injection and 3 weeks after injection using computed tomography of the neck. The measurement values were analyzed by Wilcoxon signed rank test.ResultsStatistically significant improvements were shown in all three parameters for assessing the severity of drooling after BTXA injections (p<0.05). Size of the salivary glands were significantly decreased at 3 weeks after BTXA injection (p<0.05).ConclusionSalivary gland injection with BTXA could be a useful treatment method to reduce drooling in patients with cerebral palsy and decreased size of salivary glands may partially explain the mechanism.
Objective:To investigate the training effects on balance and gait ability using balance control trainer combined with partial weight-bearing system in chronic hemiplegic stroke patients. Method: A prospective crossover clinical trial was designed. The subjects consisted of 16 chronic hemiplegic stroke patients. All patients had a stroke more than six months. In addition to conventional physical therapy (PT), 8 patients in group A were trained with the balance control trainer for 30 min/day, 5 day/week, for first 2 weeks and then received only conventional physical therapy for 2 weeks. The other 8 patients in group B received only conventional PT for first 2 weeks and then were trained with the balance control trainer for 30 min/day, 5 day/week, for next 2 weeks, with additional conventional PT. We evaluated with clinical tests including functional ambulation categories (FAC), Berg balance scale (BBS), 6 min walking distance (6mWT), timed up and go (TUG), Korean-modified barthel Index (K-MBI) and muscle strengthening of knee extensor (MMTknee) before training, 2 weeks and 4 weeks after training in those patients. Results: After training, subjects in experimental period (2weeks period of conventional PT+Balance control trainer in group A&B) showed more improvement than those in control period (2 weeks period of only conventional PT in group A&B) in FAC, BBS, 6mWT, TUG, K-MBI (p<0.05). Conclusion:We think the balance control trainer combined with the partial weight-bearing system can be a useful tool for improving balance and gait ability in chronic hemiplegic stroke patients.
