ABSTRACT
OBJECTIVES: To evaluate the use of continuous interscalene brachial plexus block with bupivacaine to treat complex regional pain syndrome (CRPS) type 1 of the shoulder in adult patients who were refractory to standard therapies. PATIENTS AND METHODS: We performed a prospective, cross-sectional study of 59 cases of treatment-refractory CRPS type 1 of the shoulder. The patients were treated with one week of continuous interscalene brachial plexus block with bupivacaine and concomitant rehabilitation in a specialist centre. After withdrawal of the catheter, rehabilitation was continued for a further 3 weeks. The outcomes at 1, 6 and 12 months were evaluated in terms of the Constant score, the verbal numeric rating scale (VNRS) for pain, joint range of motion and medication use. Patients were later interviewed by telephone and asked to state their professional situation, the current VNRS score for pain and the status of their CRPS. RESULTS: In the first month of treatment, the mean VNRS pain score fell from 7.4 to 3.6, the Constant score rose from 21.7 to 56.6% and the joint range of motion increased from 5.4 to 29.9° for external rotation (ER) position 1 and from 38.6 to 74.2° for abduction. These improvements persisted over time, despite a very slight reduction at 6 months. 86% of the interviewed patients reported that the treatment protocol had improved or greatly improvement their condition. 46% of the respondees had been able to return to work. CONCLUSION: Treatment with a combination of a 1-week continuous interscalene brachial plexus block and rehabilitation may be a good option for patients with CRPS type 1 of the shoulder and who are refractory to standard therapies.

OBJECTIVES: The aim of the study was to evaluate strength of the dorsal and plantar flexors in patients with obliterating arteriopathy of the lower limbs (stage 2) and to evaluate fatigue. POPULATION AND METHODS: The comparison was based on two groups of ten patients: one with obliterating arteriopathy, and the second with healthy limbs as a control group. Each group of patients underwent bilateral plantar flexion and dorsiflexion of the ankle on an isokinetic machine, with the following movements: three series of five movements at 120 degrees/s, then three series of three movements at 30 degrees/s in a concentric mode to evaluate strength. The exercise was repeated 20 times at 180 degrees/s to evaluate fatigue. The isokinetic parameters selected were the couple peak and ratio of workload to total weight of the patient. Tests controlled for cardiac frequency, as measured by electrocardiography, and blood pressure. RESULTS: Patients with obliterating arteriopathy of the lower limbs were generally weaker in global strength of plantar and dorsal flexors and had greater muscular fatigue than the control group (P < 0.05). CONCLUSION: Decreased performance in the leg muscles in patients with obliterating arteriopathy of the lower limbs is likely due to arterial deficit. Muscular metabolism anomalies such dysfunction of the terminal stages of the oxidative phosphorylation could also affect strength. Use of isokinetics represents an interesting possibility for treatment of patients with multiple cardiovascular abnormalities.
