Feasibility for Utilization of Assessment for Lack of Protective Sensation as Part of Foot Screening for Persons with Intellectual Disabilities.

Background

Persons with intellectual disability have a significantly higher prevalence of diabetes than the general population. Special Olympics Fit Feet, a major screening process for evaluating foot health in persons with intellectual disability, has not included an assessment for the risk of diabetic foot ulcers thus far. A probable reason for this may be that clinicians in the past have felt that persons with intellectual disability were not capable of understanding how to complete the Semmes-Weinstein test for lack of protective sensation. A study was designed to assess whether the Special Olympics athletes could complete the Semmes-Weinstein test for lack of protective sensation.

Methods

31 Special Olympics athletes with intellectual disability participating in a Fit Feet foot screening underwent a Semmes-Weinstein test for lack of protective sensation (LOPS). An assessment was completed using predetermined criteria to establish whether the subject understood what was required and could satisfactorily complete the test. Likewise, it was also determined if the Special Olympics athletes believed they understood the test.

Results

Study findings determined that approximately 67% of the athletes in the study were able to successfully complete the test and 90% of the Special Olympics athletes reported they completely understood the test. These results do not apply to the intellectual disability population at large.

Conclusion

A significant percentage of the test population appeared able to successfully undergo the Semmes-Weinstein test for lack of protective sensation (LOPS). Therefore, it is recommended that any foot screening process for Special Olympics athletes should include an assessment for loss of protective sensation including use of monofilament testing.
