Design outcomes

Primary

MeasureTime frame
residual limb pain(RLP) by using the Numerical Rating Scale(NRS) pain score between the RPNI group(Intervention group) and the conventional(Traction Neurectomy) group in patients undergoing transfemoral/transtibial amputation is lesser in RPNI when compared to traction neurectomy groupTimepoint: 1 week, 1 month and 3 months

Secondary

MeasureTime frame
Phantom limb pain(PLP) and Incidence of neuroma are both lesser in RPNI groupTimepoint: 1 week, 1 month and 3 months;Comparison of Numerical Rating scale, PainDETECT, PROMIS-P and HADS score between RPNI and traction neurectomy groupsTimepoint: 1 week, 1 month and 3 months
