“…The baseline F-wave values for both control subjects and post-stroke patients were in agreement with those reported previously (Milanov 1992b;Schiller and Stalberg 1978;Tsai et al 2001). Before footbath treatment, F-wave amplitudes and F/M ratios were higher in affected limbs of post-stroke patients than those in controls or unaffected limbs of patients.…”

“…The F-wave amplitude recorded at rest from the normal AHM was about 1-2% of the M-response amplitude, which was the same order of magnitude as that reported for hand muscles (Upton et al 1971). The small ratio recorded using surface electrodes might be due to repeated activation of a few specific neurons or infrequent responses of most anterior horn cells (Schiller and Stalberg 1978). Fisher et al (1994) published normal values for Fwave amplitudes, with a mean F/M ratio of 2.2±0.7% (range: 1.2-3.5%).…”

“…We observed that the F-wave is more straightforward to elicit under spastic conditions, and have recognized that the Fwave is superior because it could be recorded from all of the small hand and foot muscles. Several authors have reported that the F-wave amplitude is increased in spasticity (Eisen and Odusote 1979;Fierro et al 1993;Milanov 1992aMilanov , 1994Schiller and Stalberg 1978). Indeed, it is more sensitive to changes of lower motor-neuron excitability during the course of spasticity than both the T-and H-reflexes (Hultborn and Nielsen 1995;Kimura 2001;Mastaglia and Carroll 1985;Milanov 1992a, b).…”

Beneficial effects of footbaths in controlling spasticity after stroke

Footbaths are considered to provide beneficial thermal therapy for post-stroke patients with spasticity, but their anti-spastic effects have not been investigated comprehensively. The present study aimed to evaluate alterations in motor-neuron excitability using F-wave parameters in post-stroke patients with spastic hemiplegia. Subjects' legs below the knee joint were immersed in water at 41 degrees C and F-wave recordings were made over the abductor hallucis muscle before, immediately after, and 30 min after thermal treatment. Antidromic stimulation was performed on the tibial nerve at the ankle. Measurements included F-wave amplitude, F-wave/M-response ratio, changes in modified Ashworth scale (MAS), body temperature and surface-skin temperature. The mean values of both F-wave parameters were higher on the affected side before footbath treatment. In post-stroke patients, the mean values of F-wave parameters were significantly reduced after footbath treatment (P < 0.01). The anti-spastic effects of footbath treatment were indicated by decreased F-wave parameters, in parallel with decreases in MAS. Body temperature was significantly increased both immediately after, and 30 min following footbath treatment in both groups, which appeared to play an important role in decreased spasticity. Surface-skin temperature increased immediately after footbath treatment in both groups and returned to baseline 30 min later. These findings demonstrate that the use of footbaths is an effective nonpharmacological anti-spastic treatment that might facilitate stroke rehabilitation.

Study Design: Comparison of spinal lesion subjects and normal subjects. Objective: To investigate the effects of a paravertebral repetitive magnetic stimulation on spastic tone increase of the lower limbs. Setting: Munich, Germany. Methods: We compared the effects in 15 patients with different spinal lesions and in 16 healthy subjects. The spastic tone increase was evaluated clinically with the Ashworth scale and apparatively with the pendulum test, both at fixed times before and after stimulation. Unilateral stimulation was applied to the lumbar nerve roots L3 and L4 of the clinically more spastic leg. Results: The spastic tone decreased significantly in the interval between 4 and 24 h after stimulation. This effect was slightly more pronounced in the contralateral extremity. Furthermore, the stimulation motor threshold of the patients was significantly raised. Conclusion: Repetitive magnetic unilateral stimulation has a positive effect on spastic tone increase due to spinal lesions, causing a decrease that lasts for about 1 day not only on the ipsilateral but also on the contralateral side.

“…A higher incidence of F-waves and F-waves of greater magnitude relative to the maximal motor response from a muscle are considered to be a reflection of greater motoneuron excitability [83][84][85]. Although F-wave studies at the single motor unit or muscle fiber level [86][87][88][89] are more difficult to perform, these data can be used to estimate the conduction velocity of the proximal segment of the peripheral axon, a particularly useful feature when ventral root damage is suspected.…”

Abstract-This article compares some physiological methods commonly used to measure the functional capability of the motor system in humans and animals after spinal cord injury. Some of the differences between animal and human experimentation are considered first. Then we discuss how to measure the effectiveness of conduction through the motor system. We describe ways to assess the integration of different inputs at the spinal cord and to measure the responsiveness of the neuromuscular system. We conclude that comparisons across species are invaluable to understand the control of movement, both before and after injury.
