Results literature search and reasons for final selection

Included tests	Modality	Reason selected
NeuroQuick	Cold sensation	Portable, battery-operated
Neuropad	Sweat function	Easy, direct results, no training
NC-Stat DPNCheck	Nerve conduction	Portable, battery-operated
Vibratip	Vibration	Portable, battery-operated
Thermal Sensibility Tester	Warm sensation	Portable, battery-operated
Excluded tests	Modality	Reason not selected
NerveCheck	Warm, cold, pain and vibration sensation	Portable, battery operated, not available at the moment of this study
Tiptherm	Cold sensation	Weakest performance compared with other tests [19]
Neurometer	Nerve conduction	Expensive
Biothesiometer	Vibration	Expensive
Neurotip	Touch sensation	Low expected sensitivity, comparable to MFT
Neuropen	Pain sensation	Pain sensation loss is at a later stage than touch sensation loss [16, 40]
Sudoscan	Sweat function	Expensive
EzScan	Sweat function	Expensive
Bumps	Touch sensation	Low sensitivity, comparable to MFT
LDI-flare	Axon reflex–induced flare after heating skin (Doppler Imager)	Not portable, power needed
NervePace	Nerve conduction	Assesses motor latencies, while sensory conduction is more often affected in leprosy neuropathy
Neurosentinel	Nerve conduction	Similar to DPNCheck, only assessed Median nerve, which is less often affected in leprosy neuropathy
Thermotropic liquid Chrystal strip assessment	Skin temperature	Works when only one body side is affected (needs to be compared with normal side)
