A team of researchers studied the phenomenon of telescoping, the perceived shortening of the phantom limb, following limb loss. While related to well-studied concepts of phantom limb pain (PLP) and residual limb pain (RLP), telescoping remains poorly understood in pain and psychosocial outcomes. The researchers used a cross-sectional observational design to examine whether PLP and RLP intensity, pain interference, and psychosocial functioning differ between individuals who report telescoping and those who do not.
Fifty-one adults with limb loss completed measures of pain intensity, telescoping, pain interference, pain catastrophizing, neuropathic pain, pain acceptance, anxiety and depression symptoms, optimism, and resilience. Twenty-three participants (45.1 percent) reported telescoping, while 28 (54.9 percent) did not. Telescoping was more common among younger participants and those with upper-limb loss, particularly right-sided transradial limb loss. No significant between-group differences were observed for PLP intensity, RLP intensity, or pain interference. However, greater percent telescoping was associated with lower pain interference and lower PLP intensity.
Participants reporting telescoping also reported higher symptoms of anxiety and depression relative to those with normal length phantoms. The findings suggested that telescoping may reflect distress linked to symptom monitoring and potentially adaptive cortical reorganization associated with reduced PLP, according to the study’s authors.
The open-access study, “Phantom limb telescoping in individuals with limb loss: links to anxiety, depression, and pain-related measures,” was published in Frontiers in Pain Research.
