2. Fig 1
Representative examples of H-reflexes, M waves, and recruitment curves from an ABLE subject (A, B) and an SCI subject (C, D). (A, C) Single sweeps of raw data. Numbers to the right of each sweep indicate the stimulation intensity at which each response was obtained. H-reflexes and M waves were observed at appropriate latencies after the stimulation artifact. (B, D) Circles (•) represent H-reflex peak-to-peak amplitude; squares (■) are M-wave peak-to-peak amplitude. Values are presented as a proportion of the maximum M-wave and are plotted against stimulation intensity. Each point represents the mean response observed at a given stimulation intensity. Solid lines are the best-fit lines calculated from the rising portion of H-reflex and M-wave recruitment. The equations of these lines were used to calculate HTH and HGN. See Methods. Note the similarity in the appearance of the recruitment curves for the 2 subjects.

3. Fig 2
Group mean ± standard error data for (A) HTH, (B) HGN, and (C) HPP. There were no between-group differences (SCI vs ABLE) in these measures (P≥.05). Abbreviations: MGN, m-wave gain; MTH, M-wave threshold.

4. Fig 3
Correlations among HTH, HGN, and HPP. Correlation coefficients (r) are shown for the pooled data (SCI, ABLE). ∗Correlation differed significantly from zero (P≤.05). Relationships among the dependent measures were similar in both groups. Legend: ○, ABLE subjects; +, SCI subjects.
