A new cold water immersion test, immersing hands to the metacarpophalangeal (MP) joints, improves peripheral circulatory function assessment. This MP-method shows faster skin temperature recovery and less finger pain compared to the conventional wrist immersion (W-method).

Area of Science:

  • Physiology
  • Medical Diagnostics
  • Circulatory System Research

Background:

  • The conventional cold water immersion (W-method) test assesses peripheral circulatory function.
  • Improvements are needed to enhance the accuracy and subject comfort of this diagnostic test.

Purpose of the Study:

  • To evaluate a modified cold water immersion test (MP-method) for assessing peripheral circulatory function.
  • To compare the MP-method (immersion to metacarpophalangeal joints) with the W-method (immersion to the wrist).

Main Methods:

  • Twenty-seven healthy students underwent cold water immersion tests (5°C for 1 min) using two methods: MP-method and W-method.
  • Key parameters measured included skin temperature recovery, vibratory perception threshold, and finger pain.
  • Statistical analysis compared outcomes between the two immersion methods.

Main Results:

  • The MP-method demonstrated significantly faster skin temperature recovery compared to the W-method.
  • Vibratory perception thresholds were significantly lower with the MP-method.
  • Subjects reported less finger pain with the MP-method, preferring it over the W-method.

Conclusions:

  • The MP-method offers a superior approach for assessing peripheral circulatory function.
  • This modified test provides more sensitive data and improves patient comfort during evaluation.
