[Assessment for pain control efficiency of ultrasound guided adductor canal block in total knee arthroplasty: a report of 28 continuous cases].
Objective: To assess the pain control efficiency of continuous adductor canal block in total knee arthroplasty. Methods: From October to December 2015, patients with severe knee osteoarthritis undergoing primary unilateral TKA were observed clinically. All of the patients received ultrasound-guided continuous adductor canal block after surgery. ⋯ Conclusion: Ultrasound-guided continuous adductor canal block can reduce resting pain after TKA, but has a limited effect in activity pain control. Quadriceps strength had been spared after ACB, which might performearly benefits in rehabilitation. ACB-related complications need further observation to be defined.

[Needle electromyography features and values of paraspinal muscle parameters in assessment of respiratory function of patients with amyotrophic lateral sclerosis].
Objective: To analyze the features of needle electromyography (EMG) in patients with amyotrophic lateral sclerosis (ALS), and explore the correlation between EMG parameters of the tenth thoracic paraspinal muscle and disease duration, rate of disease progression, forced vital capacity (FVC) and revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R). Methods: Standard EMG was recorded from unilateral sternocleidomastoid muscle and/or tongue muscles, upper and lower limbs muscles and the tenth thoracic paraspinal muscle in 112 patients with definite ALS between March 2012 and June 2013 in the Department of Neurology at Chinese PLA General Hospital. Parameters studies included spontaneous potentials, duration and amplitude of motor unit potentials (MUP), pattern of recruitment. ⋯ Conclusions: The abnormal spontaneous activity with high frequency are fibrillation potentials and/or positive sharp waves. However, FPs is observed in a small number of patients and CRDs is rarely seen in ALS. The ALSFRS-R and peak amplitude of thetenth thoracic paraspinal muscle may be of certain clinical value in estimating the severity of disease especially the respiratory dysfunction in ALS patients.
