Painful neuromata following upper limb amputation

Painful neuromata following upper limb amputation.

Painful neuromata occurring after upper limb amputation are a significant cause of stump pain and limit the success of prosthetic training and use. There is little information in the literature regarding incidence, consequences or outcomes of painful neuromata subsequent to upper limb amputation. This article reports an analysis of thirty-two consecutive upper limb amputees. Of these 25% had mo...

Synopsis of Causation Upper Limb Amputation

Prevalence and characteristics of phantom limb pain and residual limb pain in the long term following upper limb amputation

Objectives: This study aims to describe the prevalence and characteristics of phantom limb pain and residual limb pain following upper limb amputation. Methods: One-hundred and forty-one participants (139 males; mean age 74.8 years; mean time since amputation 50.1 years) completed a self-report questionnaire assessing residual and phantom limb pain experience. Results: Prevalence of phantom lim...

Epidural electrocorticography of phantom hand movement following long-term upper-limb amputation

INTRODUCTION Prostheses for upper-limb amputees are currently controlled by either myoelectric or peripheral neural signals. Performance and dexterity of these devices is still limited, particularly when it comes to controlling hand function. Movement-related brain activity might serve as a complementary bio-signal for motor control of hand prosthesis. METHODS We introduced a methodology to i...

Cortical motor activity and reorganization following upper-limb amputation and subsequent targeted reinnervation☆

Previous studies have postulated that the amount of brain reorganization following peripheral injuries may be correlated with negative symptoms or consequences. However, it is unknown whether restoring effective limb function may then be associated with further changes in the expression of this reorganization. Recently, targeted reinnervation (TR), a surgical technique that restores a direct ne...
