Wearable therapeutic device

A wearable therapeutic device, comprising:

• a strap configured to be worn around a lumbar region of a back of a user, the strap comprising:
• a central portion;
• a first end portion extending from a first side of the central portion;
• and
• a second end portion extending from a second side of the central portion opposite the first side of the central portion;
• at least one vibration element located in the central portion;
• a near-infrared light source located in the central portion and configured to contact the back of the user when the strap is worn by the user;
• a carbon fiber heating portion located in the central portion, wherein the carbon fiber heating portion is located between the at least one vibration element and the near-infrared light source when the strap is worn by the user such that the near-infrared light source is located closer to the back of the user than the at least one vibration element when the strap is worn by the user, wherein the carbon fiber heating portion emits far-infrared light when the carbon fiber heating portion receives power from a power source in the strap;
• and
• a housing configured to secure the at least one vibration element, the near-infrared light source, and the carbon fiber heating portion.

A wearable therapeutic device, comprising:

• a strap configured to be worn around a lumbar region of a back of user, the strap comprising:
• a central portion comprising a top edge and a bottom edge, wherein the top edge of the central portion is located closer to a head of the user when the strap is worn by the user;
• a first end portion extending from a first side of the central portion, the first end portion comprising a top edge and a bottom edge, wherein the top edge of the first end portion is located closer to the head of the user than the bottom edge of the first end portion when the strap is worn by the user;
• and
• a second end portion extending from a second side of the central portion opposite the first side, the second end portion comprising:
• a top edge and a bottom edge, wherein the top edge of the second end portion is located closer to the head of the user than the bottom edge of the second end portion when the strap is worn by the user;
• and
• a controller coupled to the second end portion configured to be located in front of the user when the strap is worn by the user,
• wherein a first non-zero distance between the top edge of the central portion and the top edges of the first end portion and the second end portion in a direction approximately parallel to a spine of the user is smaller than a second non-zero distance between the bottom edge of the central portion and the bottom edges of the first end portion and the second end portion in the direction approximately parallel to the spine of the user;
• at least one vibration element located in the central portion and electrically coupled to the controller;
• a heating element located in the central portion and electrically coupled to the controller;
• a near-infrared light source located in the central portion and electrically coupled to the controller;
• and
• a far-infrared light source located in the central portion and electrically coupled to the controller,
• wherein the controller is configured to operate the at least one vibration element, the heating element, the near-infrared light source, and the far-infrared light source.
