THERMOVISUAL EVALUATION OF TEMPERATURES OF THE UPPER LIMBS FOLLOWING CRYOSTIMULATION IN POST-STROKE PATIENTS
Journal Title: Fizjoterapia Polska - Year 2008, Vol 8, Issue 1
Abstract
[b]Background. [/b]Cerebral stroke is a very serious life-threatening condition regardiess of the clinical picture at the onset. In most cases cerebral stroke is a consequence of systemic vascular diseases such as atherosclerosis or hypertension.[b]Material and methods. [/b]The study group comprised 103 patients, including 52 post-stroke patients with a paretic upper limb and 51 healthy participants. The group of stroke patients included 18 women and 34 men, while the healthy group consisted of 41 women and 10 men. The mean age of the male patients was 55.6 and of the female patients 66.1 years. The mean age of the control group was 37.2 years. Local cryostimulation was applied to the hand and forearm of the paretic limb in the stroke patients and to the hand the forearm of the right upper limb in the healthy group. The limb was exposed to cold for 6 minutes. The temperatures were measured using an Agema 570 thermovision camera.[b]Results. [/b]Subjecting only one forearm to cryotherapy procedures results in a decrease in temperature. In the post-stroke patients the return to the basseline value after the procedure was more rapid. This is possibly connected with more efficient mechanisms protecting the body against loss of warmth, since in this group temperature values were higher. In the control group the temperature in the non-cooled limb decreases by an average of 1.6 st.C, compared to only 1.3 st.C in the stroke patients.[b]Conclusions. [/b]The temperatures of an area in the forearm exposed to 6 minutes of cryotherapy were different in the post-stroke patients and in the healthy controls. This is probably attributable to stroke-related brain damage. Contralateralization, i. e. the decline of temperature in the non-cooled limb, occurred both in the post-stroke patients and in the healthy controls. Temperature decreases produced by the exposure of limbs to cold were higher in the stroke patients than in the healthy participants. The temperature returned to baseline more rapidly in the post-stroke patients. The temperature in the cooled limb dod not return to, or exceed, baseline value fifteen minutes after the procedure.
