Many studies exist suggesting that the intervention works (e.g., Kinnealey, Koenig, & Huecker, 1999) . Studies also exist suggesting that it does not work (e.g., Polatajko, 1991). An appropriate scientific conclusion is that the effectiveness of Occupational Therapy (OT) using a sensory-based approach is neither proven nor unproven. Therefore, Shaw's deduction is erroneous, and his condemnation of this type of therapy is premature given the lack of rigorous methodology in previous studies.
