Inhibition of the triceps surae stretch reflex by stimulation of the deep peroneal nerve in persons with spastic stroke Peter H. Veltink, PhD, Michel Ladouceur, PhD, Thomas Sinkjær, MD, PhD Archives of Physical Medicine and Rehabilitation Volume 81, Issue 8, Pages 1016-1024 (August 2000) DOI: 10.1053/apmr.2000.6303 Copyright © 2000 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation Terms and Conditions

Fig. 1 Measured stretch reflexes elicited in the relaxed triceps surae for varying intervals between conditioning stimulation of the deep peroneal nerve and triceps surae stretch (subject 10; stimulation level: 3 times motor threshold of the tibialis anterior). Shown are the averaged recordings of (A) soleus EMG, (B) medial gastrocnemius EMG, (C) ankle joint moment, and (D) ankle angular velocity.

Fig. 2 Average dependencies of the stretch reflexes on the interval between conditioning stimulation of the deep peroneal nerve and triceps surae stretch onset for highest levels of conditioning stimulation. (A,B,C) Relaxed triceps surae, averaged over 10 subjects. (D,E,F) Precontracted triceps surae, averaged over 7 subjects. Data are means and standard errors of the (A,D) normalized peak stretch reflex EMG for soleus, the (B,E) medial gastrocnemius, and of the (C,F) normalized mean moment. Normalized peak EMG responses are only shown for stimulation-to-stretch intervals at which the stimulus artifact did not interfere.

Fig. 3 Normalized minimum stretch reflexes after conditioning stimulation of the deep peroneal nerve (upper panel) and the intervals between conditioning stimulation and triceps surae stretch for which they occur (lower panel). For the relaxed condition (n = 10), the average mean ± standard error are shown for 3 levels of conditioning stimulation: 0.9 and 1.5 times tibialis anterior motor threshold and “max,” the highest stimulation level used for each individual subject (2 to 4 times motor threshold). Results are shown for normalized peak EMG reflex responses for soleus (●) and medial gastrocnemius (■), and for normalized mean moment (▴).

Fig. 4 The dependency of the stretch reflex in relaxed triceps surae on the ankle dorsiflexion velocity. (A,B,C) An example of the stretch velocity dependencies of the peak reflex EMG with and without conditioning stimulation for (A) soleus and (B) medial gastrocnemius and (C) of the mean moment with and without conditioning stimulation (subject 10; stimulation level: 3 times motor threshold of the tibialis anterior). The error bars indicate standard errors. Dashed lines in (A) and (B) indicate the stretch velocity dependencies of the peak reflex EMG, which were fitted with linear relations, only considering points above the velocity threshold and below reflex saturation. (D,E) The distribution of threshold differences with and without conditioning stimulation versus relative slopes of these linear fits for (D) soleus and (E) medial gastrocnemius EMG for all 10 subjects; ●, stimulation at 0.9 times motor threshold of the tibialis anterior; □, stimulation at 1.5 times this threshold; ▴, stimulation at the highest stimulation levels.

Fig. 5 Normalized areas under the relations between stretch velocity and conditioned reflex magnitude. For the relaxed condition (n = 10), the results are shown for 3 levels of conditioning stimulation: 0.9 and 1.5 times tibialis anterior motor threshold and “max,” the highest stimulation level used for each individual subject (2 to 4 times motor threshold). Results are shown for normalized peak EMG reflex responses for soleus (●) and medial gastrocnemius (■), and for normalized mean moment (▴). The normalized areas under the velocity relation for relaxed triceps surae were significantly dependent on stimulation level (ANOVA, p < .001) for the peak stretch reflex EMG of both soleus and medial gastrocnemius and p = .002 for the mean ankle moment) and significantly different from one at the maximum stimulation levels (p < .001).
