Lower limb muscles recover faster than upper limb muscles following administration of nondepolarizing neuromuscular relaxants until the train-of-four ratio (TOFR) reached 0.7. However, no study has been conducted to evaluate the recovery time of the flexor hallucis brevis muscle (FHBM), up to a TOFR of 0.9, which indicates satisfactory recovery of neuromuscular blockade. The aim of this study was to determine electromyographically the relationship between the TOFRs of the FHBM and the first dorsal interosseous muscle (FDIM), following 0.1 mg/kg of vecuronium. Eighteen patients were enrolled in this study. Electromyography of the FDIM and the FHBM was monitored. Onset times and recovery times to TOFRs of 0.7 and 0.9 of both muscles after administration of vecuronium were measured. The onset time in the FDIM was not different from that in the FHBM ( = 0.10). Recovery time to TOFR 0.7 was significantly faster in the FHBM than in the FDIM ( < 0.013). There was no significant difference in the meantime to reach TOFR 0.9 between the FDIM and the FHBM ( = 0.11). There is no clinical importance in the difference of neuromuscular recovery between the FHBM and the FDIM after TOFR reached 0.9 following administration of vecuronium.

Purpose: Recovery of the train-of-four ratio (TOFR) to > 0.9 in the upper limb is commonly used to determine that neuromuscular function has returned to the preoperative level. It is not known whether recovery of neuromuscular function can be determined in the same way using lower limb acceleromyography. We compared measurements of recovery from neuromuscular blockade using upper limb electromyography and lower limb acceleromyography. Methods: Twenty-nine patients who were scheduled for elective surgery were enrolled in this study. Patients were excluded if they had neuromuscular disease or contraindications to neuromuscular blockade. General anesthesia was induced and maintained with propofol and fentanyl. Patients were monitored using electromyography at the first dorsal interosseous muscle of the upper limb and acceleromyography at the flexor hallucis brevis muscle of the lower limb. Vecuronium 0.1 mg/kg was administered for neuromuscular blockade, and the profile of the blockade was recorded, including onset time and recovery times to TOFR 0.7 and 0.9. Results were compared between the upper and lower limbs. Results: The first dorsal interosseous muscle of the upper limb was slower to recover to TOFR 0.7 and 0.9 than the flexor hallucis brevis muscle. When the TOFR at the flexor hallucis brevis muscle had recovered to 0.9, the TOFR at the first dorsal interosseous muscle was 0.44 ± 0.23. Conclusion: Monitoring the flexor hallucis brevis muscle using acceleromyography underestimates the residual neuromuscular blockade.

Rehabilitation Exercises

Objectives. Prone bridge, unilateral bridge, supine bridge, and bird-dog are classic rehabilitation exercises, which have been advocated as effective ways to improve core stability among healthy individuals and patients with low back pain. The aim of this study was to investigate the activity of seven selected muscles during rehabilitation exercises through the signal of surface electromyographic. Approaches. We measured the surface electromyographic signals of four lower limb muscles, two abdominal muscles, and one back muscle during rehabilitation exercises of 30 healthy students and then analyzed its activity level using the median frequency method. Results. Different levels of muscle activity during the four rehabilitation exercises were observed. The prone bridge and unilateral bridge caused the greatest muscle fatigue; however, the supine bridge generated the lowest muscle activity. There was no significant difference (P>0.05) between left and right body side muscles in the median frequency slope during the four rehabilitation exercises of seven muscles. Conclusions. The prone bridge can affect the low back and lower limb muscles of most people. The unilateral bridge was found to stimulate muscles much more active than the supine bridge. The bird-dog does not cause much fatigue to muscles but can make most selected muscles active.
