Outcome measures
Primary outcome
Pulse volume recordings (triphasic/normal and non-triphasic/abnormal) of the
fingers in the dominant and non-dominant hand using photoplethysmography
Secondary outcome
* Peak systolic velocity (PSV) and luminal diameter and vessel characteristics,
such as a sign of aneurysm, stenosis, occlusion, thrombus or dissection of the
PCHA in the dominant shoulder using Color Doppler ultrasound
* Prevalence and association of digital pathology and PCHA anomalies in
symptomatic and asymptomatic elite Dutch male volleyball players.
Background summary
The prevalence of cold, blue and pale digits in the dominant hand during or
immediately after practice or competition ranged between 11% and 27% in elite
male volleyball players in the Netherlands. These symptoms are associated with
digital ischemia that can be caused by emboli due to pathological changes of
the posterior circumflex humeral artery (PCHA). However, whether the surveyed
symptoms are indeed associated with digital and PCHA pathology (PCHAP) has yet
to be revealed. Since these symptoms can also be explained by a wide variety of
other vascular pathologies.
Study objective
1a) To determine the prevalence of digital pathology, possibly as a result of
digital emboli, in the dominant hand in symptomatic and asymptomatic elite
Dutch male volleyball players.
1b) To determine the association between the presence of digital pathology in
the dominant hand with the presence or absence of symptoms of cold, blue and
pale digits in the dominant hand during or immediately after practice or
competition in symptomatic and asymptomatic elite Dutch male volleyball
players.
2a) To determine the prevalence of anomalies of the PCHA in the dominant
shoulder in symptomatic and asymptomatic elite Dutch male volleyball players.
2b) To determine the association between anomalies of the PCHA in the dominant
shoulder with the presence or absence of symptoms of cold, blue and pale digits
in the dominant hand during or immediately after practice or competition in
symptomatic and asymptomatic elite Dutch male volleyball players.
Study design
Case-control study (with the cases being symptomatic and the controls being
asymptomatic volleyball players)
Study burden and risks
There are no apparent risks for the participant being assessed by the standard
diagnostic procedures. The possible benefit for a participant is that, if an
abnormality is found, further analysis of the presence of digital pathology and
PCHA anomalies can be performed and possible irreversible damage might be
prevented.
