An implantable lead includes a lead body, having a distal end and a proximal end, configured to be implanted in a patient, and a connector provided at the proximal end. A load detection assembly is provided on the lead body, wherein the load detection assembly includes a housing that holds a sensor and a load transfer element. The load transfer element engages the sensor and conveys a force induced on the load transfer element to the sensor. Optionally, the housing may isolate the sensor from lateral forces and the load transfer element may only convey, to the sensor, longitudinal forces that are directed in a predetermined single direction. For example, the load transfer element may only convey, to the sensor, longitudinal forces that are directed perpendicular to a surface of the sensor.
