Background
To investigate the functional status and recording the most common injuries of the upper limb in male Greek boxing squad in comparison to the general population.
Methods
A retrospective injury surveillance study using an electronic questionnaire was performed in 2021. The
questionnaire was sent to male members of the Greek Boxing Federation and consisted of three parts. Demographic data, functional status scales, training conditions, hours of training, the location and description of upper limb injuries and whether the injury occurred during competition or training and also whether it was a new or a recurrent one were gathered. The same questionnaire was sent to non-boxer males (military recruits), but without asking them to report any training parameters. Inclusion criteria were age < 35 years-old for all participants and no involvement in martial arts for the control group. Also, all participants (boxers and non-boxers) completed the Patient Rated Wrist Evaluation (PRWE) scale and the Quick Disabilities of Arm, Shoulder and Hand (quick-DASH) score.
Results
The final study cohort was consisted of 62 elite or amateur boxers and 75 non-boxer males, less than
35 years old. The quick-DASH score was found to be significantly lower (better) in boxers in comparison to the general population (15.65 ± 10.25 vs. 12.55 ± 8.62; p = 0.020) whereas the PRWE score was similar in both groups (9.25 ± 14.96 vs. 8.61 ± 13.05; p = 0.843). Physical therapy sessions, thumb injuries and boxer’s knuckle were also found to be significantly higher in the boxers group. On the other hand, upper limb surgeries were significantly less in the boxers group. Finally, the size of boxing gloves was associated to the number of finger fractures, thumb injuries and ulnar sided wrist pain in boxers.
Conclusions
Although a controversial sport, boxing appears to have no long-term consequences to the upper limb function, especially regarding hand performance. The size of gloves during heavy bag training was found to be an aggravating factor for hand injuries.
