Final answer:
The COTA should position the patient’s feet slightly forward with knees flexed for a safe wheelchair to standing transfer, ensuring a larger base of support and lower center of gravity for increased stability.
Step-by-step explanation:
When assisting a patient with multiple sclerosis to transfer from sitting in a wheelchair to standing in front of the sink, the Certified Occupational Therapy Assistant (COTA) should place the patient’s feet to prepare for a safe transfer slightly forward from the knees with the knees flexed. This positioning helps in increasing stability by creating a larger base of support and lowering the center of gravity, which is essential for maintaining balance during the transfer. The position mimics how a football player prepares to receive a ball or brace for a tackle, effectively enhancing the patient's stability.
