Virtual Reality Treatment for Phantom Limb Pain

Status Completed

Clinical Trial Summary

Patients with limb amputations experience the sensation of the missing extremity, which is sometimes coupled with a persistent and debilitating pain in the missing limb, a condition known as phantom limb pain (PLP). This study will test the use of virtual reality (VR) training as a possible treatment of PLP.

Clinical Trial Description

Approximately 90% of patients with limb amputations experience the persistent sensation of the missing extremity, a phenomenon known as phantom limb (PL). Most patients with PL also experience a persistent and debilitating pain in the missing limb, a condition known as phantom limb pain (PLP).PLP is often attributed to a disruption of the primary sensory-motor representation, generating "noise" in the representation of the missing extremity, manifesting as pain. If loss of sensory feedback causes degradation of the these cortices, interventions that provide visual feedback about the missing extremity might fine-tune the primary sensory-motor cortices, thereby reducing pain. Within this framework, the present study explores the use of virtual reality (VR) training as a possible treatment of PLP. Twenty-five subjects with lower-limb amputation and chronic PLP will undergo a Virtual Reality (VR) treatment (17 one-hour sessions) consisting in two phases: a Distraction VR phase (5-7 sessions) in which they will explore VR environments using a joystick and a Lower-Limb VR treatment phase (10-12 sessions) in which they will participate in a variety of games and activities using their VR lower-limbs. A comprehensive battery for the assessment of the characteristics, intensity and the daily-life implication of PLP will be presented before and after the treatment and in three follow up testing sessions (1,4, 8 weeks). Furthermore, pain intensity will be assessed before and after each VR session. A dramatic reduction of PLP is expected after the VR treatment and that these beneficial effects remain stable in time. ;
