A pneumatic massage apparatus comprising: a massage device to be fitted to wrap around one of an arm and a leg of a patient and having at least four air chambers (5a-5f, 1-6) disposed in series in a proximal direction from a distal position of the one of the arm and the leg toward a center of a body of the patient when the massage device is fitted around the one of the arm and the leg; and a compressed air control unit supplying and discharging compressed air into and from the plurality of air chambers (5a-5f, 1-6) of the massage device; the compressed air control unit having a means for pressurizing each of the air chambers (5a-5f, 1-6) by supplying compressed air thereinto, a means for depressurizing each of the pressurized air chambers (5a-5f, 1-6) by discharging compressed air therefrom, and a means for maintaining a pressurized state of each pressurized air chamber (5a-5f, 1-6); wherein the means for pressurizing are configured to pressurize all air chambers (5a-5f, 1-6); the means for maintaining a pressurized state of each pressurized air chamber (5a-5f, 1-6) are configured to maintain the pressure for a predetermined period of time after completion of pressurization of all air chambers by the means for pressurizing; one or more pairs of mutually adjacent ones of the air chambers (5a-5f, 1-6) can be selected and the means for depressurizing are configured to depressurize the pressurized air chambers (5a-5f, 1-6) after completion of pressurization of all the air chambers (5a-5f, 1-6) in such a manner that, at least one of the pressurized air chambers (5a-5f, 1-6) except a distal end air chamber disposed at a distal-most position of the pressurized air chambers (5a-5f, 1-6) is depressurized before depressurization of the distal end air chamber, and when the pressurized air chambers (5a-5f, 1-6) are numbered sequentially in the proximal direction so that the distal end air chamber is given number one, even-numbered air chambers first start to be depressurized in descending order of numbers given thereto, and after starting to depressurize the lowest even numbered air chamber then odd-numbered air chambers start to be depressurized in descending order of numbers given thereto so that of any said selected pair of mutually adjacent ones of the air chambers (5a-5f, 1-6), a proximal air chamber of the pair first starts to be depressurized, and then a distal air chamber of the pair starts to be depressurized, to in operation urge body fluid of a patient from a body part being compressed by the distal air chamber to flow towards the body part having been compressed by the proximal air chamber until depressurization thereof; and the means for pressurizing, the means for maintaining a pressurized state and the means for depressurizing are configured to repeat the cycle of pressurization, maintaining and depressurization. a massage device to be fitted to wrap around one of an arm and a leg of a patient and having at least four air chambers (5a-5f, 1-6) disposed in series in a proximal direction from a distal position of the one of the arm and the leg toward a center of a body of the patient when the massage device is fitted around the one of the arm and the leg;
