Brief summary
Action Observation Therapy (AOT) and Motor Imagery (MI) are two rehabilitation approaches based on Mirror Neuron System (MNS). The MNS refers to a series of neurons able to activate both when one observes an action being performed or when one physically performs the action themselves. Previous studies reported that functional recovery is facilitated by asking patient observing videos with motor content (AOT) and after imagining (MI) the gestures observed. These rehabilitative apporach have been used in particular to promote functional recovery in patients with neuromotor problems, in particular in patients with stroke. To date, few studies have investigated the effectiveness of this therapeutic approach in functional recovery after orthopedic surgery and none of these applied AOT and MI in a single pre-operative session. The objective of the study is to verify whether a single administration consisting of two pre-operative sessions of AOT associated with MI can lead to an improvement of functional recovery in hip arthroplasty patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in functional mobility using Timed Up and Go test (TUG). | Both groups will be evaluated the day before (T0) and 4 days after (T1) surgery. | The primary outcome is to investigate whether a single administration consisting of two sessions of AOT and MI performed the day before the total hip arthroplasty may impact on functional recovery in the immediate post-operative period. Functional mobility will be evaluated with Timed Up and Go test. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in maximum gait speed | Both groups will be evaluated the day before (T0) and 4 days after (T1) surgery. | Changes in maximum gait speed between and within groups will be evaluated with 10 meters-walking test (10 MWT). |
| Changes in pain using Visual Analogue Scale (VAS) | Both groups will be evaluated the day before (T0) and 4 days after (T1) surgery. | Pain will be assessed with Visual Analogue Scale (VAS 0-10) ranging from 0 (absence of pain) to 10 (maximum pain) |
