NCT03512652

Brief Summary

The device "Patello" was designed to passively mobilize the Patella in cranial-caudal direction. Its application field lays in the rehabilitation of any knee pathology where knee range of motion may be restricted due to the Patella mobility.

Outcome Measures

Primary Outcomes (1)

  • Patellofemoral Translation

    Patellar cranial-caudal translation (in centimeters) is assessed repeatedly within a single passive continuous mobilization session. A total of 50 repetitions are performed at a constant mobilization speed. Ultrasound video sequences are recorded, and patellar translation is analyzed immediately after 1, 10, 20, 30, and 50 repetitions during the same session.

    Assessed after 1, 10, 20, 30 and 50 mobilization repetitions during a single continous passieve patellar moblizitaion session of 50 repetitions (total duration approximately 5-10 minutes)

Study Arms (1)

Patello

EXPERIMENTAL

The participants' right knee was placed inside the patello device, a total of 50 repetitions, with a constant mobilisation speed, was conducted and the degree of translation was assessed after 1, 10, 20, 30 and 50 repetitions.

Device: Patello

Interventions

PatelloDEVICE

The Patello is a new intervention device which mobilizes the Patella passively and continuously in cranial-caudal direction to increase Patella mobility.
