Local and Systemic Cardiovascular Effects from Monochromatic Infrared Therapy in Patients with Knee Osteoarthritis: A Double-Blind, Randomized, Placebo-Controlled Study
Figure 4
Changes in blood pressure with monochromatic infrared treatment. Solid square: treatment group; hollow square: placebo group; T0: before treatment; T1: after 10 min of treatment; T2: after 20 min of treatment; T3: after 30 min of treatment; T4: after 40 min of treatment; T5: 5 min after treatment; T6: 15 min after treatment. (a) systolic blood pressure; (b) diastolic blood pressure. Between groups by repeated-measure ANCOVA: systolic blood pressure: group effect: ( = 1.18); time effect: ( = 1.53); group x time interaction effect: ( = 0.38); diastolic blood pressure: group effect: ( = 0.19); time effect: ( = 0.65); group x time interaction effect: ( = 0.53).
