Electronic Thesis and Dissertation Repository
Operant conditioning of short-latency reflex (SLR) and H-reflex have been investigated in animals and humans. We modified previously established protocols for conditioning lower limb H-reflexes to up-condition the SLR in brachioradialis muscle and to investigate the effect of such conditioning on the long-latency response (LLR) of synergistic muscles. Our study included 12 healthy participants. Each participant took part in 3 baseline and 27 conditioning sessions in 6 weeks, followed by two additional sessions one month and two months after the last conditioning session. We found an increase in SLR magnitude in 50% of participants (by 15%±2.50). However, there was no …

Purpose: Immature auditory processing has been proposed to underlie language impairments in children with developmental language disorder (DLD; also known as specific language impairment). Using newly available normative auditory evoked potential (AEP) waveforms, we estimated AEP maturity in individual children with DLD and explored whether this maturational index was related to their language abilities.
Method: AEPs were elicited by 225 trials of a 490-Hz pure tone. Using intraclass correlation and our previously established normative AEP waveforms of 7- to 10-year-old children with typical development, we estimated the age equivalent of the AEPs (AEP-age) from 21 children with DLD. The relation …
