To the Editor: We read with interest the article from Murphy et al. entitled “Intraoperative Acceleromyography Monitoring Reduces Symptoms of Muscle Weakness and Improves Quality of Recovery in the Early Postoperative Period.”1 Indeed, the authors confirmed previous findings that objective acceleromyographic neuromuscular monitoring may improve perioperative neuromuscular management.2 In the current study this improved perioperative management led to a better spontaneous recovery at the time of neostigmine administration: 61 of 76 patients in the acceleromyographic group compared with 41 of 74 patients in the control group had a train-of-four (TOF) count of 4 when neostigmine was given: P = 0.014.

Neuromuscular monitoring by intensive care nurses: comparison of acceleromyography and tactile assessment. DOUBLE BURST STIMULATION (DBS): A NEW PATTERN OF NERVE STIMULATION TO IDENTIFY RESIDUAL NEUROMUSCULAR BLOCK. + Author Affiliations Accepted July 5, 1988.
We present a new pattern of nerve stimulation—double burst stimulation (DBS)—to detect residual neuromuscular block manually. The DBS consists of two short lasting, 50-Hz tetanic stimuli or bursts separated by a 750-ms interval. The response to this pattern of stimulation is two single separated muscle contractions of which the second is less than the first during non-depolarizing neuromuscular blockade. Journal of Anesthesia, Volume 3, Number 1. Automatic monitoring of patient relaxation status. The Strain Gage. When external forces are applied to a stationary object, stress and strain are the result.
Stress is defined as the object's internal resisting forces, and strain is defined as the displacement and deformation that occur. For a uniform distribution of internal resisting forces, stress can be calculated (Figure 2-1) by dividing the force (F) applied by the unit area (A): Strain is defined as the amount of deformation per unit length of an object when a load is applied. Strain is calculated by dividing the total deformation of the original length by the original length (L): Typical values for strain are less than 0.005 inch/inch and are often expressed in micro-strain units: Strain may be compressive or tensile and is typically measured by strain gages. Fundamentally, all strain gages are designed to convert mechanical motion into an electronic signal.
The ideal strain gage would change resistance only due to the deformations of the surface to which the sensor is attached. Wireless Sensors Overview. Phase IV is the only wireless sensor company that offers products, custom design services, and expert help with every wireless technology.

Pattern of Pulses That Maximize Force Output From Single Human Thenar Motor Units. Abstract We assessed the sequence of nerve impulses that maximize force output from individual human thenar motor units.
When these motor units were stimulated intraneurally by a variable sequence of seven pulses, the pattern of pulses that elicited maximum force always started with a short (5–15 ms) interpulse interval termed a “doublet.” The twitch force summation caused by this “doublet” elicited, on average, 48 ± 13% (SD) of the maximum tetanic force. The peak amplitude of “doublet” forces was 3.5 times that of the initial twitches, and twitch potentiation appeared to have little influence on twitch force summation elicited by the “doublets.” For some units, the second optimal interpulse interval was also short. Subjects and experimental setup Four men and three women with no history of any neurological disorder were chosen as research subjects.
