The Swallowing Proficiency for Eating and Drinking (SPEAD) test is reliable for assessing swallowing in healthy adults aged 20-79. Normative data helps Speech-Language Pathologists identify oral and pharyngeal swallowing difficulties across various consistencies.
Area of Science:
- Speech-language pathology
- Swallowing disorders
- Clinical assessment
Background:
- Current swallowing evaluations often use single bolus consistencies, limiting generalizability.
- The Swallowing Proficiency for Eating and Drinking (SPEAD) test evaluates oral and pharyngeal swallowing phases with multiple consistencies.
Purpose of the Study:
- To establish normative data for the SPEAD test in healthy individuals aged 20-79 years.
- To provide a reliable and valid tool for Speech-Language Pathologists (SLPs).
Main Methods:
- 112 healthy adults aged 20-79 were divided into three age groups.
- Participants consumed water, thickened Electral, and Parle Monaco biscuits.
- Swallowing events were video recorded for analysis.
Main Results:
- The SPEAD test demonstrated excellent internal consistency and inter-rater reliability.
- Older adults showed increased swallow events, longer duration, and slower ingestion rates.
- Significant differences in SPEAD indices were observed across the three consistencies (p < 0.01).
Conclusions:
- The SPEAD test is a feasible, reliable, and valid tool for assessing swallowing in healthy Indian adults (20-79 years).
- Established normative data aids SLPs in diagnosing oral and pharyngeal swallowing impairments across different bolus types.
