Final answer:
Gross MMT assesses muscle strength in a general way to identify significant weaknesses, while specific MMT provides a detailed evaluation of individual muscles or groups for precise measurements.
Step-by-step explanation:
The difference between gross and specific testing for Manual Muscle Testing (MMT) involves the scope and detail of the assessment conducted to evaluate muscle strength. Gross testing refers to a general assessment to broadly determine muscle strength and whether any significant weakness exists. It is usually a quick screening to evaluate the major muscle groups collectively. On the other hand, specific testing involves a detailed and more focused approach, assessing individual muscles or muscle groups to determine the exact level of strength or weakness.
Gross testing might be utilized in initial evaluations or in circumstances where a quick assessment is necessary. Specific testing is applied when precise strength measurement is crucial, such as in developing a rehabilitation program or tracking progress over time.
