A clinical assessment tool coupled to a walking aid for enhancing a therapist's observation-based gait assessment with use of additional objective and quantitative data such as acceleration, angular velocity, and applied forces. The assessment tool facilitates appropriate assistive gait device prescription, provides patients and therapists feedback during gait training, and reduces wrist and shoulder injuries with walking aid usage. The assessment tool is configured to detect timing and speed of walking aid, placement, angular acceleration of the walking aid, and amounts of weight borne on the walking aid.

Walking aid and system and method of gait monitoring

Systems and methods are provided for controlling lateral movement of a medical capsule system. A capsule housing is configured to be inserted into an anatomical structure of a patient. The multichannel tether is coupled to a rear of the capsule and includes at least one liquid exhaust channel conveying liquid to the capsule housing. The plurality of liquid exhaust ports are positioned around an outer circumference of the capsule housing and each configured to controllably expel liquid laterally from the capsule housing at varying rates to affect lateral movement of the capsule housing.

Hydro-jet endoscopic capsule and methods for gastric cancer screening in low resource settings

Systems and methods are described for determining an orientation and position of a capsule inserted into the body of a patient. A magnetic field is applied to an area of the patient where the capsule is located. Sensor data, including inertial data from an inertial sensor and magnetic field data indicative of the applied magnetic field as detected by at least one magnetic field sensor, is wirelessly received from the capsule. An orientation angle of the capsule is determined based at least in part on the inertial data. The magnetic field data is compared to known characteristics of the applied magnetic field and a location of the capsule is determined based on the comparison.

Real-time pose and magnetic force detection for wireless magnetic capsule

A system and method for detecting a tissue property. The system comprises a first unit positioned outside a patient body and a second unit positioned inside the patient's body. The first unit includes a first housing, and a magnetic field source supported by the first housing. The second unit includes a second housing, a pressure sensor supported by the second housing, a localization module supported by the second housing, a controller, and a power source. The pressure sensor is configured to detect an indentation force applied to the tissue, and the second unit is configured to wirelessly transmit the indentation force data and localization data to a computer to generate a volumetric stiffness map for the tissue.
