Effect of Stuttering Remediation Exercises on Cortical Auditory Evoked Potentials

Study Overview
=================
Brief Summary
-----------------
studying how the cortical auditory evoked potentials differ in children who stutter from who do not stutter and how these potentials change with therapy

Detailed Description
-----------------
Measuring amplitude and latency of P1, N1, P2 N2 between a group with developmental stuttering and a control group with no stuttering at baseline. Recording the potentials through passive listening to a 60dB stimulus and active speaking, describing pictures and rapid naming. Assigning the group with stuttering to remediation exercises using fluency shaping program for 2 to 4 months then remeasuring amplitude and latency of the previously mentioned potentials.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Children who stutter<br>Measuring stuttering severity and cortical auditory evoked potentials in a group of children who stutter then they will receive fluency shaping exercises for a period range from 2-4 months. Reassessment of cortical auditory evoked potentials and stuttering severity after the specified period | Behavioral: Fluency shaping exercises<br>* Training for prolonged speech, easy onset, light contact and abdominal breathing moving from the level of single words till using short sentences describing pictures<br>|
| No Intervention: children who do not stutter<br>Measuring cortical auditory evoked potentials as a comparison group | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference in latency of cortical auditory evoked potentials in children with stuttering compared to children who do do not stutter | Measuring latency in millisecond of P1, N1 using the commercial system (Interacoustic Eclipse TM) device during passive listening to a 60dB auditory stimulus and active speaking conditions | baseline: before intervention | 
| Change in latency of cortical auditory evoked potentials in children with stuttering due to stuttering intervention program | Measuring latency in millisecond of P1, N1 in the group who stutter after intervention using the commercial system (Interacoustic Eclipse TM) device during passive listening to a 60dB auditory stimulus and active speaking conditions | immediately after intervention | 
| Difference in amplitude of cortical auditory evoked potentials in children with stuttering compared to children who do do not stutter | Measuring amplitude in microvolt of P1, N1 using the commercial system (Interacoustic Eclipse TM) | baseline: before intervention | 
| Change in amplitude of cortical auditory evoked potentials in children with stuttering due to stuttering intervention program | Measuring amplitude in microvolt of P1, N1 in the group who stutter after intervention using the commercial system (Interacoustic Eclipse TM) device during passive listening to a 60dB auditory stimulus and active speaking conditions | immediately after intervention |
