RESUMO
Dry needling is a procedure commonly performed for the relief of myofascial pain disorders. The procedure is generally well tolerated. Adverse events often are mild, but severe complications have been reported. This case report describes an acute spinal epidural hematoma as a complication of dry needling. It is a reminder to the performing physician or therapist to take specific precautions when placing a needle near the spine. Sudden onset of neuropathic pain after needling therapy in and around the spine should prompt emergency assessment with possibly advanced spine imaging to evaluate the integrity of the spinal cord. LEVEL OF EVIDENCE: V.

OBJECTIVE: To assess the efficacy of transcranial direct current stimulation (tDCS) on decreasing upper-limb (UL) muscle tone after stroke. DESIGN: A prospective, sham-controlled, randomized controlled trial with 4-weeks follow-up. Randomization into the tDCS group or the control group. SETTING: Rehabilitation education and research hospital. PARTICIPANTS: Inpatients (N=90, 45 per group; age range, 15-70y; 69 men, 21 women; duration of stroke, 2-12mo) with poststroke UL spasticity. No participant withdrew because of adverse effects. INTERVENTION: The tDCS group received tDCS to the primary sensorimotor cortex of the affected side with cathodal stimulation, 20 minutes per day, 5 days per week, for 4 weeks and conventional physical therapy. The control group received sham stimulation (same area as the tDCS group) and conventional physical therapy. MAIN OUTCOME MEASURES: Modified Ashworth scale (MAS), Fugl-Meyer Assessment of motor recovery, and Barthel Index. All outcomes were measured at admission, after treatment, and after follow-up. A clinically important difference (CID) was defined as a reduction of ≥1 in the MAS score. RESULTS: Compared with the sham tDCS group, the active tDCS group had significantly more patients with a clinically important difference after treatment (80% and 78% vs 6% and 9%) and at 4-week follow-up (84% and 82% vs 7% and 4%), and UL motor function and activities of daily living (ADL) assessment improved more significantly in the active tDCS group (Fugl-Meyer Assessment of motor recovery from 12 [range, 4-26] to 22 [range, 7-50] to 32 [range, 28-41], Barthel Index from 55 [range, 0-85] to 85 [range, 5-100] to 90 [range, 10-100 vs Fugl-Meyer Assessment of motor recovery from 8 [range, 3-34] to 10 [range, 8-25] to 15 [range, 6-40], Barthel Index from 55 [range, 25-95] to 65 [range, 30-100] to 75 [range, 40-100], respectively, P<.01). CONCLUSIONS: UL muscle tone after stroke can be decreased using cathodal tDCS. Combined with conventional physical therapy, tDCS appears to improve motor function and ADL. Cathodal tDCS over ipsilesional primary sensorimotor cortex may inhibit primary sensorimotor cortex hyperactivation, resulting in significant reductions in muscle tone.

OBJECTIVES: The aim of the study is to investigate the cortical response to painful and auditory stimuli for subjects in persistent vegetative state (PVS) and minimal conscious state (MCS), and measure the interconnection of the residual cortical functional islands with electroencephalographic (EEG) nonlinear dynamic analysis (NDA). METHODS: Thirty PVS subjects, 20 MCS subjects and 30 subjects in normal conscious state (NCS) were involved in the study. EEG was recorded under three conditions: eyes closed, auditory stimuli and painful stimuli. EEG nonlinear index of cross-approximate entropy (C-ApEn) was calculated for all subjects. RESULTS: Interconnection of local and distant cortical networks of patients in PVS was generally suppressed, and painful or auditory stimulation could hardly cause any activation of associative cortices. Instead, interconnection of local cortical networks of patients in MCS improved significantly. The only significant difference with the NCS existed in the unaffected distant cortical networks. CONCLUSIONS: Interconnection of local and distant cortical networks in MCS is superior to that of PVS. NDA could measure interconnection of the residual cortical functional islands with associative cortices in the unconscious patients. SIGNIFICANCE: NDA can characterise the interconnection of cortical networks for the unconscious state and provide some information of unconsciousness at the awareness level.

BACKGROUND: A randomized clinical has shown the effectiveness of intramuscular electrical stimulation for the treatment of poststroke shoulder pain. OBJECTIVE: Identify predictors of treatment success and assess the impact of the strongest predictor on outcomes. METHOD: This is a secondary analysis of a multisite randomized clinical trial of intramuscular electrical stimulation for poststroke shoulder pain. The study included 61 chronic stroke survivors with shoulder pain randomized to a 6-week course of intramuscular electrical stimulation (n = 32) versus a hemisling (n = 29). The primary outcome measure was Brief Pain Inventory Question 12. Treatment success was defined as > or = 2-point reduction in this measure at end of treatment and at 3, 6, and 12 months posttreatment. Forward stepwise regression was used to identify factors predictive of treatment success among participants assigned to the electrical stimulation group. The factor most predictive of treatment success was used as an explanatory variable, and the clinical trials data were reanalyzed. RESULTS: Time from stroke onset was most predictive of treatment success. Subjects were divided according to the median value of stroke onset: early (<77 weeks) versus late (> 77 weeks). Electrical stimulation was effective in reducing poststroke shoulder pain for the early group (94% vs 7%, P < .001) but not for the late group (31% vs 33%). Repeated-measure analysis of variance revealed significant treatment (P < .001), time from stroke onset (P = .032), and treatment by time from stroke onset interaction (P < .001) effects. CONCLUSIONS: Stroke survivors who are treated early after stroke onset may experience greater benefit from intramuscular electrical stimulation for poststroke shoulder pain. However, the relative importance of time from stroke onset versus duration of pain is not known.

OBJECTIVE: Assess the effectiveness of intramuscular electrical stimulation in reducing hemiplegic shoulder pain at 12 mos posttreatment. DESIGN: A total of 61 chronic stroke survivors with shoulder pain and subluxation participated in this multiple-center, single-blinded, randomized clinical trial. Treatment subjects received intramuscular electrical stimulation to the supraspinatus, posterior deltoid, middle deltoid, and upper trapezius for 6 hrs/day for 6 wks. Control subjects were treated with a cuff-type sling for 6 wks. Brief Pain Inventory question 12, an 11-point numeric rating scale was administered in a blinded manner at baseline, end of treatment, and at 3, 6, and 12 mos posttreatment. Treatment success was defined as a minimum 2-point reduction in Brief Pain Inventory question 12 at all posttreatment assessments. Secondary measures included pain-related quality of life (Brief Pain Inventory question 23), subluxation, motor impairment, range of motion, spasticity, and activity limitation. RESULTS: The electrical stimulation group exhibited a significantly higher success rate than controls (63% vs. 21%, P = 0.001). Repeated-measure analysis of variance revealed significant treatment effects on posttreatment Brief Pain Inventory question 12 (F = 21.2, P < 0.001) and Brief Pain Inventory question 23 (F = 8.3, P < 0.001). Treatment effects on other secondary measures were not significant. CONCLUSIONS: Intramuscular electrical stimulation reduces hemiplegic shoulder pain, and the effect is maintained for > or =12 mos posttreatment.

OBJECTIVE: To assess the effectiveness of intramuscular neuromuscular electric stimulation (NMES) in reducing poststroke shoulder pain. DESIGN: Multicenter, single-blinded, randomized clinical trial. SETTING: Ambulatory centers of 7 academic rehabilitation centers in the United States. PARTICIPANTS: Volunteer sample of 61 chronic stroke survivors with shoulder pain and subluxation. INTERVENTION: Treatment subjects received intramuscular NMES to the supraspinatus, posterior deltoid, middle deltoid, and trapezius for 6 hours a day for 6 weeks. Control subjects were treated with a cuff-type sling for 6 weeks. Main outcome measure Brief Pain Inventory question 12 (BPI 12), an 11-point numeric rating scale administered in a blinded manner at the end of treatment, and at 3 and 6 months posttreatment. RESULTS: The NMES group exhibited significantly higher proportions of success based on the 3-point or more reduction in BPI 12 success criterion at the end of treatment (65.6% vs 24.1%, P<.01), at 3 months (59.4% vs 20.7%, P<.01), and at 6 months (59.4% vs 27.6%, P<.05). By using the most stringent "no pain" criterion, the NMES group also exhibited significantly higher proportions of success at the end of treatment (34.4% vs 3.4%, P<.01), at 3 months (34.4% vs 0.0%, P<.001), and at 6 months (34.4% vs 10.3%, P<.05). CONCLUSIONS: Intramuscular NMES reduces poststroke shoulder pain among those with shoulder subluxation and the effect is maintained for at least 6 months posttreatment.
