Cardiovascular and Metabolic Strain during Stochastic Resonance Therapy in Stroke Patients
Hypertension as one of the established risk factors for stroke can damage vessels. Therefore training with strenuous exercises that might cause very high blood pressure should be avoided in patients with stroke.

In a cross-sectional study 20 patients with a recent stroke performed a SRT with an individual sub-maximum vibration-frequency. Training consisted of 5 series of 1 minute each with 1 minute rest in-between. Blood pressure, heart rate and lactate were measured before (at rest) and during SRT.
Exercise physiology as the study of the function of the human body during various acute and chronic exercise conditions.
Heart rate varied between 93 and 101 bpm, lactate between 1.8 – 1.9 mmol/l and mean blood pressure fluctuated on the level 130-140/90-100 mmHg. Strain caused by SRT is comparable to strain between values during rest and aerobic threshold.
These results are favourable terms and conditions precedent for future intervention studies using SRT in rehabilitation of strength, balance and gait in patients after stroke
