Walsh, DPhil, Jean Claude Willer, MD, DSc  Archives of Physical Medicine and Rehabilitation  Volume 81, Issue 3, Pages (March 2000) DOI: /S (00) Copyright © 2000 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation Terms and Conditions

2 Fig. 1 Details of the experimental procedure, illustrating the placement of the TENS/IFT electrodes, skin thermistor probes, and the H-reflex and RIII reflex stimulation and recording electrodes.

3 Fig. 2 Typical monosynaptic reflexes (H-reflex) recorded from the tibial nerve below the union of the bellies of gastrocnemius after stimulation of the nerve at the level of the popliteal fossa. Negative peak latency (NPL) is indicated.

4 Fig. 3 Summary of H-reflex negative peak latency (NPL) difference scores plotted against time for each of the experimental groups under investigation (mean ± SEM; n = 10 all groups). Any positive values (ie, above baseline) represent a decrease in conduction velocity. ■, IFT 5Hz; ▴, IFT 100Hz; ●, IFT 200Hz; □, TENS 5Hz; ▵, TENS 100Hz; ○, TENS 200Hz; ⊕, control.

7 Fig. 6 Summary of RIII area difference scores plotted against time for each of the experimental groups under investigation (mean ± SEM; n = 10 all groups). Any negative values (ie, below baseline) represent a hypoalgesic effect. ■, IFT 5Hz; ▴, IFT 100Hz; ●, IFT 200Hz; □, TENS 5Hz; ▵, TENS 100Hz; ○, TENS 200Hz; ⊕, control.

8 Fig. 7 Summary of RIII maximum amplitude difference scores plotted against time for each of the experimental groups under investigation (mean ± SEM; n = 10 all groups). Any negative values (ie, below baseline) represent a hypoalgesic effect. ■, IFT 5Hz; ▴, IFT 100Hz; ●, IFT 200Hz; □, TENS 5Hz; ▵, TENS 100Hz; ○, TENS 200Hz; ⊕, control.

9 Fig. 8 Summary of VAS difference scores plotted against time for each of the experimental groups under investigation (mean ± SEM; n = 10 all groups). Any negative values (ie, below baseline) represent a hypoalgesic effect. ■, IFT 5Hz; ▴, IFT 100Hz; ●, IFT 200Hz; □, TENS 5Hz; ▵, TENS 100Hz; ○, TENS 200Hz; ⊕, control.
