Aims

Improvements in the evaluation of outcome after nerve transfers are required. The assessment of force using the Medical Research Council (MRC) grades (0 to 5) is not suitable for this purpose. A ceiling effect is encountered within MRC grade 4/5 rendering this tool insensitive. Our aim was to show how the strength of flexion of the elbow could be assessed in patients who have undergone a re-innervation procedure using a continuous measurement scale.

Methods

A total of 26 patients, 23 men and three women, with a mean age of 37.3 years (16 to 66), at the time of presentation, attended for review from a cohort of 52 patients who had undergone surgery to restore flexion of the elbow after a brachial plexus injury and were included in this retrospective study. The mean follow-up after nerve transfer was 56 months (28 to 101, standard deviation (sd) 20.79). The strength of flexion of the elbow was measured in a standard outpatient environment with a static dynamometer.
