Quantification of the Neurological Examination [36]

Manual testing of isometric strength in individual muscles. Quantification into five levels	Grade 5: Contraction against powerful resistance, normal power (score = 0) Grade 4+: Contraction against gravity and strong resistance (score = 1) Grade 4: Contraction against gravity and moderate resistance (score = 2) Grade 4-: Contraction against gravity and slight resistance (score = 3) Grade 3: Contraction against gravity (score = 3) No pareses minor than grade 3 were observed
Sensibility to light touch, pain (pinprick), and vibration (tuning fork 256 Hz). Quantification into three levels	Normal (score = 0) Mild/any deviation of sensibility (score = 1) Marked deviation of sensibility (score = 2)
Nerve trunk mechanosensitivity assessed by palpation. Quantification into four levels	No/normal tenderness (score = 0) Mild/any mechanical allodynia (score = 1) Medium mechanical allodynia (score = 2) Marked mechanical allodynia (score = 3)
