A Special test of the Circulation & Swelling

• These examinations are used clinically to evaluate hand edema.
• When there is swelling in the hand, a therapist or doctor will do this clinical examination.
• In the observation phase of the evaluation of the hand, this swelling is examined.

Name of the special blood circulation and swelling test is:

• Digit blood flow
• Hand volume test

Digit blood flow Test:

• This digit blood flow is used to define the blood flow in the hand

What is the procedure for the digit blood flow?

• In order to perform the test, the position of the patient is in seating position.
• The examiner (therapist) compresses the nail bed to measure the distal blood flow and records how long it takes for the nail’s color to recover.
• Normally, the color should return to the nail bed within 3 seconds of the pressure being removed.
• The fingers should be checked for arterial insufficiency if the recovery takes longer.
• The effect is a comparison with the normal side and gives some indication of the determined flow.

Hand volume test:

What is the importance of the hand volume test?

• This hand volume test is used to find out if the hand is swollen, edematous, or atrophy.

Hand volume test

• The position of the patient is in a sitting position.
• A volumeter may be utilized if the examiner (therapist) is worried about variations in hand size.
• This tool may be used to measure changes in hand size based on atrophy, widespread edema, or localized swelling.
• The examiner [therapist] can get an understanding of the changes taking place in the affected hand by making comparisons with the normal part.
• For accurate readings on this test, care must be used.
• The difference between the dominant and non-dominant hands, as well as between the right and left hands, is frequently 10 ML.
