A history of trauma can affect a child’s capacity to express emotions due to the neurological footprints left from neglect and abuse. Oftentimes, children do not have a caregiver as a protector which leaves them vulnerable to harm. In response, children use emotional survival strategies of either flight or fight to adapt to their stressful environment. Occupational Therapy Practitioners (OTP) are positioned to address social and emotional development; however, they often feel ill equipped to address the complexity of trauma and its impact on emotions. OTPs need to look at each sensory system from a nurturing/grounding perspective using movement-based strategies as inroads to address the child’s emotional capacity. A sensory integration intervention, Proprioceptive Activities to Lower Stress (PALS), was developed to study the effect on a six-year-old boy’s expressions of emotions using a single subject design. Three emotions were measured using a facial analysis system, Noldus FaceReader™. The emotions were happiness, sadness, and neutral. Neutral is defined as the level of emotional detachment. Results indicate a statistically significant improvement in the expressions of happiness and sad post the PALS program.
