Testimonial: Going to Back to School with ADHD

How IM helped Anna get A’s & B’s in school, take better initiative & demonstrate improvement in her temper tantrums.

Anna is a 9-year-old girl diagnosed with ADHD who had difficulty with focusing, distractibility, organizational skills, & reading comprehension. She was easily bored and exhibited moodiness as well as emotional meltdowns. She tended to be hypersensitive and extremely frustrated by the end of the day, in addition, she also displayed emotional problems toward her mother.

The results of neuropsychological testing indicated a diagnosis of ADHD, combined type, where both attention and inattention and hyperactivity/impulsivity are present.


The following tests were administered prior to Anna starting her Interactive Metronome training: Math Fluency Subtest of the Woodcock-Johnson-III, Test of Variables of Attention (TOVA), Working Memory and Processing Speed Sections of the Wechsler Intelligence Scale for Children-IV (WISC-IV), Conner’s Parent Rating Scales.

Neuropsychological Testing revealed the following results:

  • Demonstrated significant problems with attention with the remainder of her executive functions intact.
  • Language testing revealed problems with repetition, nonsense words, and rapid naming.
  • Memory and learning abilities were average to high average. Interference effects were noted while performing learning tasks.
  • Social perception was within normal limits as were measures of visual-spatial perception.
  • Significant weaknesses were noted in intellectual measures of working memory.
  • Verbal comprehension and perceptual reasoning were significant strengths.
  • Academic testing indicated Anna was functioning at grade level. However, weakness was observed in math fluency.
  • Personality measures indicated significant ADHD-type behaviors in the home environment in addition to oppositionality and psychosomatic-type behaviors. These were not as noticeable in the school environment.


Anna completed 14 sessions of the Interactive Metronome Program, which consisted of 20,000 repetitions over all 14 IM exercises. An initial Long Form Assessment indicated overall performance at 82.9 milliseconds, which is in the below-average range of functioning. Anna made 75% early hits and 25% late hits.

Re-evaluation upon conclusion of Interactive Metronome training indicated performance of 26.2 milliseconds off target, which is now in the exceptional range of functioning. Anna made 56% early hits and 44% late hits upon re-evaluation. Overall task average improved, ranging from 35% to 89% improvement. Variability improved from – 119% to a maximum improvement of 90%. SRO improvement started low at 70% and improved to a high of 530%.

Behaviorally, the family noticed that Anna was taking better initiative. Grades were now all A’s and B’s. She was learning better ways to study and also demonstrated improvement in her temper tantrums.


These results are compared to Anna’s initial Neuropsychological Testing.

Test of Variables of Attention (TOVA)

Anna demonstrated significant improvement on the TOVA. Reaction time variability improved from a standard score of 43 to 92. Response time improved from a standard score of 61 to 111. D prime declined slightly from 74 to 73. Commission errors showed a decline in performance from a standard score of 97 to 71. Overall omission errors improved from a standard score of 41 to 77. Anna attained an ADHD score of -1.66 relative to an initial ADHD score of -7.63. Thus, there has been an overall improvement in her performance on this measure of sustained attention.

Math Fluency Subtest of the Woodcock-Johnson-III

Results of math fluency testing indicate significant improvement from an initial standard score of 91 to a current standard score of 117. This corresponds to an improvement in grade equivalent from 4.5 to 9.1. This equates to an improvement in percentile rank from 26 to 88.

Working Memory and Processing Speed Sections of the Wechsler Intelligence Scale for Children-IV (WISC-IV)

Working Memory809
Processing Speed9742

Results of working memory measures indicate there has been no change in working memory as Anna initially attained an IQ of 80. Processing speed improved slightly from 94 to 97.

Conner’s Parent Rating Scale

Anna made significant improvement on the Conner’s Parent Rating Scale. The following are pre versus post Interactive Metronome results:

Cognitive Problem/Inattention7759
Conner's ADHD Index8061
Conner's Global Index - Restless/Impulsive
Conner's Global Index - Emotional Lability8754
Conner's Global Index Total 9060
DSM-IV Inattentive8466
DSM-IV Hyperactive/Impulsive6963
DSM-IV Total8466

Results of the Conner’s Rating Scale indicate significant improvement in the area of oppositional behavior, cognitive problems, inattention, and hyperactivity. Psychosomatic behaviors have also decreased. All ADHD indices have decreased significantly. Mild improvement is also noted on a measure of hyperactive and impulsive behaviors.


Significant improvement was noted post Interactive Metronome training on measures of sustained attention, fluency skills, and behavioral indices of ADHD. No significant changes were noted on measures of working memory and processing speed.

In all likelihood, as Anna was tested at the end of the day and had not taken her stimulant on that day, the cognitive improvement was attributable to the IM and not the effects of stimulants. However, the behavioral measures of ADHD probably represent a combined improvement of both the effects of psychostimulant medication and Interactive Metronome.
