  • transfer of Brachioradialis motor branch to the anterior interosseous nerve in c8 t1 brachial plexus palsy an anatomic study
    Microsurgery, 2013
    Co-Authors: M Antonio D Garcialopez, Eduardo Fernández, Francisco Martinez
    Abstract:

    We present an anatomical and histomorphometric study of the transfer of the motor branch to the Brachioradialis muscle to the anterior interosseous nerve in recent brachial plexus lesions, involving C8 and T1 roots. The aim of this study was to demonstrate the anatomic constancy of the nerves involved in the transfer, feasibility, and reproducibility of the transfer. We performed a study of 14 elbows in fresh cadavers. Transfer of the motor branch of the Brachioradialis muscle to the anterior interosseous nerve was possible in all specimens; there was constancy in the origin and entry into the muscle of the donor nerve, and it was always possible to dissect the recipient nerve at the level of the donor nerve, thereby allowing for direct coaptation of the nerves. The mean diameter of the anterior interosseous nerve was 2.9 ± 0.5 mm and the mean diameter of the Brachioradialis muscle branch was 2 ± 0.4 mm. The branch to the Brachioradialis muscle contains an average of 550 ± 64 myelinated axons and the anterior interosseous nerve has an average of 2266 ± 274 myelinated axons. The anatomic study in cadavers showed that the technique is justified and anatomically reproducible. © 2012 Wiley Periodicals, Inc. Microsurgery, 2013.

  • transfer of the nerve to the Brachioradialis muscle to the anterior interosseous nerve for treatment for lower brachial plexus lesions case report
    Journal of Hand Surgery (European Volume), 2011
    Co-Authors: Antonio Garcialopez, Francisco Martinez, Pablo Sebastian, David Perea
    Abstract:

    In lower lesions of the brachial plexus (C8–T1) there is good function of the shoulder, elbow, and wrist, although that of the hand is impaired. Reconstruction of finger flexion is generally obtained by tendon transfer. We present a case report involving transfer of the motor nerve branch of the Brachioradialis muscle to the anterior interosseous nerve to restore finger flexion in acute lower brachial plexus lesion.

  • Vibromyographic quantification of voluntary isometric contractile force in the Brachioradialis.
    Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and, 2006
    Co-Authors: Jason P Cole, Guruprasad Madhavan, Kenneth J Mcleod
    Abstract:

    This study investigated the ability of vibromyography (VMG) to accurately represent voluntary forearm muscle contractile force during attempted-isometric contraction of the Brachioradialis. VMG signals were collected from the Brachioradialis of healthy adult men (mean age, 26.6+/-9.8 years, N=24) during attempted-isometric contraction over a force range of 4.45 N to maximum sustained load. The VMG signals were decomposed using wavelet packet analysis techniques, and the corresponding wavelet packets were utilized in a multiple regression model for parameter reduction and identification of signal components which best correlated to muscle force. It was observed that just two wavelet components were sufficient to accurately predict muscle force (R2=0.984, P

    Abstract:

    This study investigated the ability of vibromyography (VMG) to accurately represent voluntary forearm muscle contractile force during attempted-isometric contraction of the Brachioradialis. VMG signals were collected from the Brachioradialis of healthy adult men (mean age, 26.6 ± 9.8 years, N=24) during attempted-isometric contraction over a force range of 4.45N to maximum sustained load. The VMG signals were decomposed using wavelet packet analysis techniques, and the corresponding wavelet packets were utilized in a multiple regression model for parameter reduction and identification of signal components which best correlated to muscle force. It was observed that just two wavelet components were sufficient to accurately predict muscle force (R 2 = 0.984, P < 0.0001). The signal force relationship observed is monotonic, though quadratic in form. More importantly, the wavelet data was able to predict Absolute force output of the Brachioradialis without normalization or prior knowledge of a subject's maximum voluntary force. These data show that VMG recordings are capable of providing a monotonic relationship between VMG signal and muscle force. Moreover, in contrast to EMG technology which can only provide relative force levels, VMG appears to be capable of reporting absolute force levels, an observation which is expected to lead to numerous applications in medicine and rehabilitation
