ASSIGNED GRADE FOR OVERALL QUALITY:  B-The highest possible grade, based on the design of the investigation is A.  The Assigned Grade for Overall Quality represents a judgment about the level of evidence supporting the intervention. It is not a judgment about the quality of the evidence

 

TAKE AWAY:  This investigation provides preliminary support for the effectiveness of Modified Melodic Intonation Therapy (MMIT) over a short course (i.e., 2 sessions) of intervention. The results indicated that MMIT but not the Control group (no treatment) evidenced significant improvements comparing test performance before and after Session 1 for Adjusted Total Score and a Responsive Task. For the comparison of the pretest for Visit 1 to Visit 2, both MMIT and the Control Group improved significantly on the Adjusted Total Score. However, only MMIT improved significantly for the Responsiveness Task and only the Control Group improved for the Repetition Task.

–  The MMIT group’s change from pretest1 to posttest1 was larger than the Control group’s  0.62 (moderate effect)

–  The Control group’s change from pretest1 to posttest1 was larger than the Control group’s 0.05 (negligible effect)

 

  • OUTCOME #2:Improved performance on an investigator-developed measure of that was based on the Responsive Section of the Western Aphasia Battery (WAB)

–  The MMIT group change from pretest 1 to posttest 1 was larger than the Control group’s change for items 2 and 3 but not 1 through 3:  0.57 (moderate effect)

–   The MMIT Group’s change was larger than the Control group change from pretest 1 to pretest 2:  1.08 (large effect)

 

  • OUTCOME #3:Improved overall adjusted performance on an investigator-developed measure that was based on the of the Western Aphasia Battery (WAB)

–  The MMIT group change from pretest 1 to posttest 1 was larger than the change for the Control Group: 0.83 (large effect)

– The MMIT group’s change was larger from pretest 1 to pretest 2:  0.67 (moderate effect))

 

 

  1. Were maintenance data reported?No

 

 

  1. Were generalization data reported? Yes
  • For the most part, the stimuli from the pre and post test measures differed from the treatment stimuli and can be considered to be evidence of generalization. The first item from both the Responsiveness and Repetition Tasks was also a treatment target. Reanalysis of the outcomes with the removal of the first item on both targets showed findings similar to the original results.

 

 

  1. Describe briefly the experimental design of the investigation.
  • Thirty Ps who had been diagnosed with nonfluent aphasia were randomly assigned to receive 2 or more treatments of Modified Melodic Intonation Therapy (MMIT; n = 16) or No Treatment (Control; n = 14.)

 

  • AllPs were tested pre and post intervention for each treatment session using investigator-developed measures modeled on the WAB. Test administrators were blinded to the group assignment of the P they were testing.

 

  • Reliability and treatment fidelity data were not presented.

 

  • Ps received 2 or more treatment sessions but only the data from the first 2 sessions were analyzed.

 

 

ASSIGNED OVERALL GRADE FOR QUALITY OF EXTERNAL EVIDENCE:  B-

 

 

SUMMARY OF INTERVENTION

 

PURPOSE: To investigate the benefits of Modified Melodic Intonation Therapy (MMIT)

 

POPULATION:  Nonfluent Aphasia

 

MODALITY TARGETED: Production

 

ELEMENTS/FUNCTIONS OF PROSODY TARGETED (do not list the specific dependent variables here):  music (rhythm, pitch)

 

ELEMENTS OF PROSODY USED AS INTERVENTION:  music (rhythm, pitch)

 

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED:  scores on measures of Repetition, Responsiveness, and the Total on an investigator designed instrument.

 

 

DOSAGE: number of days between onset and initial treatment session ranged from 13 to 16 days; 2 individual sessions; 10 to 15 minutes in length

 

ADMINISTRATOR:  Music Therapist (MT)

 

MAJOR COMPONENTS:

 

MMIT PROCEDURES

 

  • MMIT is a modification of Melodic Intonation Therapy. The modifications include

– The C develops a sentence list (target stimuli) containing full novel sentences that are meaningful to the P. The target stimuli are sung with pitch and rhythm similar to that of normal speech, rather than intoned speech.

 

–   Session 1:

∞ C selects one sentence to use throughout this session.

∞ C reads aloud the target sentence. C subsequently sings the sentence.

∞ C sings the sentence multiple times as a model and then directs the P to sing it.

∞ C facilitates P’s singing by helping P to tap the rhythm of the target sentence with P’s left hand.

 

– Session 2:

∞ C uses the same procedure as Session 1 and decides whether or not to add a second sentence.

 

– Session 3:

∞  C uses the same procedure as Session 1 and adds third sentence.

∞ Only 4 Ps participated in the third session. These data were not analyzed.

 

CONTROL GROUP PROCEDURES

 

  • C met with P for 10 to 15 minutes.

 

  • C discussed topics such as possible treatments, outcomes, comorbid conditions associated with aphasia.

ASSIGNED GRADE FOR OVERALL QUALITY:  Not graded. This thesis involves a survey regarding attitudes about speech-language pathology and music therapists and is not directly concerned with the application of an intervention. Accordingly, it is not assigned a grade.

 

TAKE AWAY: This investigation explored the views about professional interactions between music therapists (MTs) and speech-language pathologists (SLPs) using survey methodology. It is not a therapy investigation; rather it provides useful information about the application of music to speech-language pathologists, the targeting of speech-language goals in music therapy, and professional interactions between speech-language pathologists (SLPs) and music therapists (MTs). The results suggest that while SLPs are generally open to co-treatment with other disciplines, they have only limited experience co-treating and being consulted by other professions.

ELEMENTS/FUNCTIONS OF PROSODY TARGETED:  stress, music

ELEMENTS OF PROSODY USED AS INTERVENTION:  duration, loudness, pitch

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: production of word or phrase

MAJOR COMPONENTS:

  • The clinician (C) can focus on either one aspect of prosody or multiple aspects of prosody depending on the age of the child.
  • For example, C may encourage the participant (P) to use duration alone to mark stress or to use pitch, loudness, and duration.
  • This activity can also be used to focus on target words/phrases to be produced in the songs.

 

 Toys that Provide Auditory Feedback

POPULATION:  Childhood Apraxia of Speech; Children 

MODALITY TARGETED: production 

ELEMENTS/FUNCTIONS OF PROSODY TARGETED:  loudness, music

ELEMENTS OF PROSODY USED AS INTERVENTION:  rhythm

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: production of syllables

MAJOR COMPONENTS:

  • Toys with embedded microphones can facilitate the production of different aspects of prosody.
  • The use of drums can encourage the production of loudness or of targeted syllables.

 

Action Figures, Dolls, and Stuffed Animals

POPULATION:  Childhood Apraxia of Speech; Children

MODALITY TARGETED: production 

ELEMENTS/FUNCTIONS OF PROSODY TARGETED: pitch, loudness

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: voice quality; words/phrases

MAJOR COMPONENTS:

  • Role playing with action figures, dolls, and stuffed (plush) animals can focus on prosody by encouraging P to use different speaking styles for different characters and to signal different meanings.
  • C encourages target words/phrases production as part of the play.

 

Board Games

POPULATION:  Childhood Apraxia of Speech; Children 

MODALITY TARGETED: production

ELEMENTS/FUNCTIONS OF PROSODY TARGETED:  rate, contrastive stress

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: voice quality 

MAJOR COMPONENTS:

  • Before taking a turn P imitates sentences/phrases modeled by C with

– different voice qualities or

– different rates

  • C asks P questions to elicit contrastive such as

– Is it YOUR turn or MY turn?  (p. 2)

– Does your character have BLUE eyes? (p. 2.)

Books

POPULATION:  Childhood Apraxia of Speech; Children 

MODALITY TARGETED: production 

ELEMENTS/FUNCTIONS OF PROSODY TARGETED:  affective prosody

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: literacy 

MAJOR COMPONENTS:

EMERGING READERS:

  • When reading with the P, C has him/her complete a sentence that signals

– an emotion,

– emphasis,

–  a character voice (p. 2.)

 

READER:

  • C identifies passages that could benefit with modifications of prosody to enhance interest.
  • C provides reading material a little below P’s reading level when P is practicing prosodic modifications during reading aloud activities.

  • Ps were randomly assigned to treatment or no treatment groups. However, the assignments were not fully random because the investigators controlled for several P characteristics.
  • All Ps were assessed at the beginning and end of the treatment phase for the Treatment group. The investigators assessed the reading skills of the Ps using a published test of reading. Outcome measures were derived from the assessments.
  • The investigators compared the change for the Outcome measures to assess the effectiveness of the treatment.
  • The Ps in the Treatment group received the intervention in their home schools. The investigators reported that there was variability with respect to implementation.

  1. Describe briefly the experimental design of the investigation.
  • Seventeen Ps were selected to determine to replicate the finding of the Proof of Concept study with a larger group.

 

  • The 17 Ps each participated in 25 treatment sessions and served as his/her control. The 25 sessions dosage is markedly reduced from the Proof of Concept study but was used because of the burden of 40 sessions for families. The decision also was made to use 25 sessions because almost 90% of the change in the Proof of Concept study had been achieved by session 25.

 

  • The investigators performed multiple initial preintervention assessments of the outcome and used the best performance of each P as his/her baseline.

 

  • Following the 10thsession and every 5 sessions after the 10th, the investigators performed an assessment or probe session. Probe sessions were similar to the treatment sessions except they included both trained and untrained (generalization) stimuli. Each Ps’ clinician (C) administered the probes but the ratings of correct/incorrect were performed by a blinded rater.

ASSIGNED OVERALL GRADE FOR QUALITY OF EXTERNAL EVIDENCE:  B-

 

 

 

SUMMARY OF INTERVENTION

 

PURPOSE: To determine if a music-based intervention (AMMT), based on Melodic Intonation Therapy, warrants additional research

 

POPULATION:  ASD

 

MODALITY TARGETED:  production

 

 

ELEMENTS OF PROSODY USED AS INTERVENTION:  music (rhythm, intonation, pitch), rate.

 

OTHER ASPECTS OF LANGUAGE/COMMUNICATION TARGETED: Articulation

 

DOSAGE:  45 minute individual sessions for 40 (Proof of Concept study) or 25 sessions (Replication study or Comparison study)

 

ADMINISTRATOR:  probably SLP

 

 

MAJOR COMPONENTS:

 

  • Two treatments were described in the article:AMMT and SRT

 

 

AUDITORY-MOTOR MAPPING TRAINING (AMMT)

 

  • AMMT is derived from Melodic Intonation Therapy.

 

  • The main objective of AMMT is to increase speech sound accuracy and intelligibility.

 

  • AMMT involves scaffolding, massed practice, spaced practice, and several behavioral management techniques.

 

  • Clinicians (Cs) model intoned bisyllables at 1 syllable per second using 2 pitch levels that corresponded to naturalspeech. The C accompanied the production of the intoned bisyllables with tapping of an electronic drum using the same pitches as the intoned modeled bisyllables. Again, the rate is one tap per second.

 

  • There are 5 hierarchical steps in AMMT:

–  Listening:  The C produces a model of the bisyllable target word at the end of a sentence. Example: “It is fun to blow bubbles” (p. 6.)  The target was intoned using the 2 pitches and the intoning was accompanied the tapping of an electronic drum.

 

–  Unison: C and P produce the bisyllable target word together. Example:  C says: “Let’s say it together:  bubbles” (p. 6.) The target was intoned using the 2 pitches and the intoning was accompanied the tapping of an electronic drum.

 

–  Unison Fade: C says the first syllable of the bisyllable target word, cuing P to produce the whole target. Example:  C says: Again:  bu….”   (p. 6.) The target was intoned using the 2 pitches and the intoning was accompanied the tapping of an electronic drum.

 

–  Imitation: C models the target word and directs P to imitate. The target was intoned using the 2 pitches and the intoning was accompanied the tapping of an electronic drum. Example:

∞  C says: “My turn: bubbles.” (p. 6)

∞  C says: “You turn …..”  (p. 6)

 

–  Cloze: C elicits the independent production of the bisyllable target from P. Example: “Last time It’s fun to blow …..” (p. 6.).

 

  • Each session involved 15 bisyllable target words in which each was practiced 5 times before moving to the next target.

 

 

SPEECH REPETITION THERAPY  (SRT)

 

  • SRT used the same procedures at AMMT without the intoning and drumming.
