“…The demonstrated changes in skin blood flow immediately after cold water immersion in this study are consistent with changes in limb blood flow reported by Levy et al, [49]. These authors noted an increase in skin blood flow measured by plethysmography after hand immersion in cold water at 4°C.…”

Study Design: Repeated Measures.Objectives: To determine the short term impact of cold water immersion on sensory and vascular functions in patients with Distal Radius Fracture (DRF) and compare responses in the injured and uninjured hands.Background: Cold exposure is used to assess neurovascular function. Cold is also used as therapeutic agent to reduce pain and swelling. There is a scarcity of trials that have looked at the impact of cold exposure in patients with DRF.Methods: Twenty patients with DRF, aged 18 to 65 yrs. were recruited after cast removal. All patients underwent Immersion in Cold water Evaluation (ICE) which consisted of 5 min of hand immersion in water at 12°C. Skin Blood Flow (SBF) in hands, Skin Temperature (S Temp.) in index and little fingers and sensory Perception Thresholds (sPT) at 2000Hz (for Aβ fiber) and 5 Hz (for C fiber) were obtained from ring finger, before ICE, immediately after (0 min, 1 min) and 10 min later. Differences were analyzed using repeated measures. Results:In the DRF hand, SBF increased immediately (Mean Difference = -42.2 A.U), at 1 min (-35 A.U) and 10 min after ICE (-1 A.U). Skin Temp. In index and little fingers decreased immediately after ICE (9.9°C and 9.1° C) and did not return to baseline by 10 min (4°C and 4.1°C). ICE had no effect on sPT at 5 Hz (p>0.05). There was no difference between the DRF and uninjured hand on all measures(p>0.05) except for the sPT at 2000Hz, which remained high on the DRF side for up to 10 min (-1.8 m. A). Conclusion:Normal cold responses consistent with 'hunting reaction' were observed after ICE in both hands. Aβ fibers on DRF side became less sensitive after ICE. These findings suggest that a brief immersion in cold water does not produce any adverse events associated with cold exposure.
