Inclusion Criteria

Clinical diagnosis of Cerebrovascular accident (CVA), minimum lesion duration of 6 months, degree of spasticity between 1 and 3 on the modified Ashworth scale, capacity to obey simple verbal commands and absence of degenerative diseases or orthopedic-traumatic lesions in ankle articulation.

Exclusion Criteria

Hypersensitivity to ice or to electric current, inability to withstand the intensity of the electric current used to record H-reflex and M response and non-attendance at the three assessment days were established as exclusion criteria.

Primary Outcome Measures

Name	Time	Method
There was a reduction in the Hmax/Mmax ratio (P=0.0006) registered by the electromyography (EMG).[30 minutes following Transcutaneous Electrical Nerve Stimulation (TENS) application.];There was an increase in the Hmax/Mmax ratio (P=0.0007) and an increase in the latency (P=0.0001) registered by the electromyography (EMG).[30 minutes after ice application.];EMG amplitude was not significantly altered.[30 minutes following Transcutaneous Electrical Nerve Stimulation and ice application.]

Secondary Outcome Measures

Name	Time	Method
H-reflex latency registered by the electromyography (EMG) was significantly lower in the affected limb (P=0.0375).[Non-affected limb compared to the affected limb before any aplication.];The Hmax/Mmax, H-reflex latency and EMG amplitude of the muscle antagonist of the spastic muscle was not significantly altered[30 minutes after control.];The Hmax/Mmax registered by the electromyography (EMG) was significantly higher in the affected limb (P=0.0245).[Non-affected limb compared to the affected limb before any aplication.];The Electromyogram amplitude of the muscle antagonist of the spastic muscle was decreased in the compromised limb (P< 0.0001).[Non-affected limb compared to the affected limb before any aplication.];Statistically significant differences were found when the Hmax/Mmax ratio (P<0.0001) and H reflex latency (P<0.0001) registered by the electromyography (EMG) were compared between post-TENS, post-cryotherapy and control.[When post-TENS, post-cryotherapy and control were compared.]
