Overview

Electromyography, somatosensory evoked potentials, pulmonary function studies, peak height velocity, and computerized photogrammetry may be helpful in the diagnosis of scoliosis.

Other Diagnostic Studies

Other diagnostic studies for scoliosis include electromyography (EMG), somatosensory evoked potential (SSEP), pulmonary function test (PFT), peak height velocity, and computerized photogrammetry.

Electromyography (EMG)

  • In literature, it has been demonstrated that changes in the EMG activity of the paraspinal muscles during the development and progression of the scoliotic curve.[1][2][3][4][5]
  • EMG of the paraspinal muscles are of value for predicting the progression in idiopathic scoliosis.
  • Increased EMG activity has been noted on the convex side of the scoliotic curve.
  • Higher amplitude of Motor unit Action potential (MUP) on the convexity side was the most prominent abnormal findings in our adolescent idiopathic scoliosis (AIS) patients.
  • The amplitude of MUPs correlates to the degree of scoliosis with no significant effect on progression of AIS curve according to the Cobb angle.

Somatosensory Evoked Potential (SSEP)

SSEP of median nerve.Source: By Medicus of Borg - Own work, CC BY-SA 4.0
  • Preserving the integrity of the spinal cord during a surgical maneuver is vital.[6][7][8][9][10][11][12]
  • Intraoperative neurophysiologic monitoring (IOM) provides guidance to surgeons and reduces the risk of permanent neurologic complications.
  • A somatosensory evoked potential study determines whether the spinal nerves can send and receive sensory messages, and how quickly these messages are transmitted between the nerve and brain.
  • SSEP amplitude recorded before skin incision is used as the reference baseline.
  • A 50% decrease in the amplitude from baseline is set as the alarm threshold for intra-operative neural damage.
  • SSEP can be affected by anesthesia and hypotension.

Pulmonary Function Test (PFT)

Peak Height Velocity

  • Curve progression in idiopathic scoliosis is related to growth.[17]
  • Peak height velocity is a maturity scale directly related to growth and the adolescent growth spurt.
  • Recommendations for bracing and operative intervention rely on the ability to assess the growth potential of these patients.
  • Once peak height velocity is identified, the timing of cessation of growth can be reliably predicted, so that patients can be told well in advance how long they will need to wear an orthosis.

Computerized Photogrammetry

  • Photogrammetry can be regarded as the science and technology of obtaining spatial measurements, and other geometrically reliable information, derived from photographs.
  • Few studies have exhibited equivalent scoliosis angle measurements in patients compared with the traditional Cobb radiographic method.[18]
