The aim was to investigate trial-by-trial response characteristics in the short-latency stretch reflex (SSR). Fourteen dorsiflexion stretches were applied to the ankle joint with a precontracted soleus muscle on 2 days. The magnitude and variability of trial-by-trial responses of the SSR were assessed. The SSR was log-normally distributed and variance heterogeneous between subjects. For some subjects, the magnitude and variance differed between days and stretches. As velocity increased, variance heterogeneity tended to decrease and response magnitude increased. The current study demonstrates the need to assess trial-by-trial response characteristics and not averaged curves. Moreover, it provides an analysis of SSR characteristics accounting for log-normally distributed and variance heterogeneous trial-by-trial responses.

Velocity Input

The effect of baclofen on walking performance was examined in nine spastic multiple sclerosis patient. In addition, nine healthy subjects were tested as controls. The modulation of the short latency soleus stretch reflex was closer to normal with baclofen compared to the recordings without baclofen, the modulation index being 74% (range: 60-100) with baclofen and 62% (range: 20 -100) without baclofen, P=0.03. In healthy subject the modulation index was 100% (range: 52 -100). In the early swing phase the threshold of the soleus stretch reflex was significantly higher during baclofen medication being 139 degls (range: 63 -302) compared with 93 degls (range: 37-187) with out baclofen, P=0.004. The relation between the stretch velocity (input) and the amplitude of the stretch reflex (output) in early swing phase was unchanged being 0.27 μVs/deg (range: 0.1-1.51) in patient with baclofen and 0.24 μVs/deg (range: 0.08-0.79) without baclofen, P=0.25. Baclofen induced no change in input-output properties of the stretch reflex during walking compared with findings in a sitting position at matched EMG activity. There was a significant correlation between clinical spasticity score and stretch reflex threshold in the early swing phase (p=-0.61, P=0.04) and between clinical spasticity score and the slope of the best linear fit in the early swing phase (p=0.72, P=0.009).
