Optical measurement system, portable optical measurement device used therein, and rehabilitation planning method using same

An optical measurement system, comprising a main optical measurement device and a portable optical measurement device, wherein

• said main optical measurement device comprises:
• a first case;
• a first plurality of first light sending devices (A) irradiating a subject with light;
• a first plurality of first light receiving devices (B) receiving light emitted from said subject;
• a display device;
• a first holder to be worn on the head of said subject, to which at least through holes are provided to support the first plurality of first light sending devices and the first plurality of first light receiving devices;
• and
• a control unit provided inside said first case for controlling said first light sending devices and said first light receiving devices so as to obtain measurement data on the brain's activity and display the measurement data on the display device, and
• said portable optical measurement device comprises:
• a second case that is portable by a subject;
• a second plurality of second light sending devices (C) irradiating the subject with light;
• a second plurality of second light receiving devices (D) receiving light emitted from said subject;
• a second holder to be worn on the head of said subject, to which through holes are provided to support the second plurality of second light sending devices and the second plurality of second light receiving devices;
• a control unit provided inside said second case for controlling said second plurality of second light sending devices and said second plurality of second light receiving devices so as to obtain measurement data on the brain's activity;
• and
• a communication unit that can communicate with said main optical measurement device, wherein
• (C+D)≧(A+B) is satisfied, and
• the communication unit of said portable optical measurement device transmits the measurement data obtained by the control unit of said portable optical measurement device to the main optical measurement device.
