简要总结
The primary aim of this study is to assess the changes in strength expression resulting from the performance of a surgical operation among orthopedic surgeons at the IRCCS Galeazzi-Sant'Ambrogio Hospital. To achieve this goal, the assessment of strength expression will be conducted using handgrip measurements before (pre) and after (post) the surgical operation. Additionally, both pre- and post-surgery, there will also be evaluations of changes in actigraphic sleep parameters, salivary cortisol levels, cognitive performance, and subjective perception levels of effort and drowsiness.
Te second aim is to assess differences in strength expression, cognitive performance, salivary cortisol levels, perceived effort, and drowsiness levels among surgeons in response to sleep hygiene strategies (week 2 vs week 3).
详细描述
Currently, there are few scientific studies that have assessed the relationship between sleep quality, strength expression, and cognitive performance among orthopedic surgeons. Furthermore, no previous study has ever evaluated the effect of a behavioral sleep hygiene strategy on actigraphic sleep parameters in orthopedic surgeons.
Therefore, the primary aim of the study is to assess the changes in strength expression resulting from the performance of a surgical operation among orthopedic surgeons at the IRCCS Galeazzi-Sant'Ambrogio Hospital. To achieve this goal, the assessment of strength expression will be conducted using handgrip measurements before (pre) and after (post) the surgical operation. Additionally, both pre- and post-surgery, there will also be evaluations of changes on lower limbs strength (maximal isometric strength of extensors of knee by digital dynamometer), salivary cortisol levels, cognitive performance (Stroop test and Bomb Risk Elicitation Task), and subjective perception levels of effort and drowsiness (Borg CR-10 and Karolinska Sleepiness Scale).
Te second aim is to assess differences in strength expression, cognitive performance, salivary cortisol levels, perceived effort, and drowsiness levels among surgeons in response to sleep hygiene strategies (control week vs Sleep hygiene strategies week).
The study involves 3 weeks of assessment (Week 1, 2, and 3), not necessarily consecutive.

研究组 & 干预措施
Sleep Hygiene Strategies (SHS)
In Week 3, the study participants will implement sleep hygiene strategies. Specifically, these sleep hygiene strategies will be applied for all seven days of Week 3 and will involve the guidelines recommended by the National Sleep Foundation.
干预措施: Sleep Hygiene Strategies (Behavioral)
结局指标
主要结局
Handgrip Test
时间窗: The handgrip test is conducted on the seventh day of both Week 2 and Week 3, taking approximately 4 minutes to complete. The test is performed both before and after the surgery.
Handgrip is a measure of the maximal isometric force that a hand can squeeze, and it is widely used because very easy and inexpensive. The handgrip strength is performed three-times for each hand alternatively, starting with the dominant hand, using a digital dynamometer to the nearest 0.1kg. Participants perform the test in a sitting position with the shoulder adducted, elbow flexed at 90-degree angle, forearm in neutral position. Participants rest 30 seconds among each repetition. The peak of the three repetitions is calculated and use for statistical analysis.
