Therapeutic electrical stimulation therapy for patient gait freeze

A medical system comprising:

• one or more electrodes;
• and
• one or more processors configured to:
• sense, via the one or more electrodes, a bioelectrical signal of a brain of a patient while the patient performs movement associated with freezing of gait and while the patient is not experiencing an episode of freezing of gait;
• determine, based on the bioelectrical signal, that the patient is susceptible to freezing of gait while the patient is not experiencing an episode of freezing of gait;
• and
• in response to determining that the patient is susceptible to freezing of gait, program a medical device to:
• detect movement associated with freezing of gait;
• and
• deliver, to the patient and in response to detecting the movement associated with freezing of gait, electrical stimulation therapy configured to suppress freezing of gait.

A non-transitory computer-readable medium comprising instructions, that, when executed, cause one or more processors to:

• sense, via one or more electrodes, a bioelectrical signal of a brain of a patient while the patient performs movement associated with freezing of gait and while the patient is not experiencing an episode of freezing of gait;
• determine, based on the bioelectrical signal, that the patient is susceptible to freezing of gait while the patient is not experiencing an episode of freezing of gait;
• and
• in response to determining that the patient is susceptible to freezing of gait, program a medical device to:
• detect movement associated with freezing of gait;
• and
• deliver, to the patient and in response to detecting the movement associated with freezing of gait, electrical stimulation therapy configured to suppress freezing of gait.

A medical system comprising:

• means for sensing a bioelectrical signal of a brain of a patient while the patient performs movement associated with freezing of gait and while the patient is not experiencing an episode of freezing of gait;
• means for determining, based on the bioelectrical signal, that the patient is susceptible to freezing of gait while the patient is not experiencing an episode of freezing of gait;
• and
• means for programming, in response to determining that the patient is susceptible to freezing of gait, a medical device to:
• detect movement associated with freezing of gait;
• and
• deliver, to the patient and in response to detecting the movement associated with freezing of gait, electrical stimulation therapy configured to suppress freezing of gait.
