Abstract: Literature has shown that there is a high prevalence rate for children with cerebral palsy (CP) and severe mental handicap (SMH) experiencing feeding problems because of oromotor dysfunction. Adverse effects of feeding problems on children's growth and caregiving-related stress have been identified. This study. adopting an experimental design, aimed to examine the clinical efficacy of a Jaw Rehabilitation Program (JRP) on children with CP and SMH. A total of 42 eligible subjects were recruited and finally 40 of them completed the program. They were randomly assigned into either the experimental group or the control group. The experimental group completed in a 10-weeks JRP training whilst the control group only received the conventional school oromotor training program. Three primary oromotor parameters (sensory acceptance, sustain closure, repetitive bite) and one functional parameter (functional bite) were measured at four time points: baseline, midway of the experiment, post-intervention, and post-2-week intervention. Results of two-way repeated ANOVA showed that there is progress in most of the biting and chewing skills of the experimental group. In terms of the fundamental jaw motor and sensory responses, sensory acceptance to external materials, sustain closure and repetitive jaw movement are found to have different extent of improvement. A positive correlation between experimental bite and functional bite is also noted, showing that generalization effect of the masticatory skills acquired is present. In summary of this preliminary study, the JRP is proved to be having positive effect to the development of biting and chewing skills.
