Registered outcomes10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Handgrip Test | 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. |
| Secondary | Lower limbs isometric strength | The maximal isometric strength test of extensors of knee is conducted on the seventh day of both Week 2 and Week 3, taking approximately 5 minutes to complete. The test is performed both before and after the surgery. | Maximal isometric strength of extensors of knee is measured, for both lower limbs alternatively, using a digital dynamometer with subjects in a sitting position and the knee placed at 90° flexion. A resting period of 30-seconds is given after each repetition. The peak of the three repetitions is calculated and used for statistical analysis. |
| Secondary | Sleep monitoring | Seven days for each timepoint period (week 1, week 2 and week 3. 21 days in total) | Sleep parameters are objectively monitored by actigraphy. Also, participants complete a validated daily sleep diary to record bedtime, wake-up time, the number and duration of nocturnal awakenings, daytime napping, and subjective sleep quality. Data derive both from the sleep device and sleep diaries are used to determine the quantity and quality of sleep that participants obtain (Total sleep time; Sleep efficiency; Immobility time; Moving time; Fragmentation index; Wake after sleep onset; Subjective quality of sleep; Subjective sleepiness; Subjective tiredness). Sleep is monitored for seven consecutive days for each timepoint period (week 1, week 2 and week 3). |
| Secondary | Stroop Test | The Stroop test is conducted on the seventh day of both Week 2 and Week 3, taking approximately 2 minutes to complete. The test is performed both before and after the surgery. | The Stroop test is a psychological assessment that evaluates cognitive processing speed and selective attention. The Stroop test involves presenting words in different colors and asking participants to name the color of the ink used to print the word. |
| Secondary | Bomb Risk Elicitation Task | The Bomb Risk Elicitation Task is conducted on the seventh day of both Week 2 and Week 3, taking approximately 2 minutes to complete. The test is performed both before and after the surgery. | The Bomb Risk Elicitation Task is a behavioral experiment designed to measure risk preferences under uncertainty. The task involves decision-making in a context where participants face varying levels of risk and potential gains or losses. |
| Secondary | Salivary cortisol | The assessment of salivary cortisol using "Salivette" is conducted on the seventh day of both Week 2 and Week 3, taking approximately 3 minutes to complete. The assessment is performed both before and after the surgery. | Assessment of salivary cortisol levels using Salivette tubes (Sarsted, Germany) |
| Secondary | Borg CR-10 | The Borg CR-10 evaluation is conducted on the seventh day of both Week 2 and Week 3, taking approximately 1 minute to complete. The assessment is performed both before and after the surgery. | Borg CR-10 is a tool used to measure subjective perception of exertion during physical activity. This scale assesses an individual's subjective perception of effort or exertion during exercise, ranging from 0 (no exertion at all) to 10 (maximal exertion). |
| Secondary | Karolinska Sleepiness Scale | The Karolinska Sleepiness Scale evaluation is conducted on the seventh day of both Week 2 and Week 3, taking approximately 1 minute to complete. The assessment is performed both before and after the surgery. | The Karolinska Sleepiness Scale is a subjective self-assessment tool used to measure a person's level of sleepiness or alertness at a particular moment in time. This scale helps individuals rate their perceived sleepiness on a scale from 1 (Very alert) to 9 (Extremely sleepy, can't stay awake). |
| Secondary | Pittsburgh Sleep Quality Index | The Pittsburgh Sleep Quality Index evaluation is conducted at the end of Week 1, and taking approximately 4 minute to complete. | The Pittsburgh Sleep Quality Index is a widely used self-report questionnaire that assesses an individual's sleep quality over a one-month time interval. It evaluates various aspects of sleep, including duration, latency, habitual sleep efficiency, disturbances, use of sleep medications, and daytime dysfunction. The global score ranging from 0 to 21, where higher scores indicate poorer sleep quality. |
| Secondary | Morningness-Eveningness Questionnaire | The Morningness-Eveningness Questionnaire is conducted at the end of Week 1, and taking approximately 4 minute to complete. | The Morningness-Eveningness Questionnaire (MEQ) is a self-report questionnaire designed to assess an individual's chronotype, which refers to their preference for being active and alert during certain parts of the day. Based on the responses, individuals are scored on a scale (range from 16 to 86) that categorizes them into different chronotypes: * Morning types (score: 59-86) * Intermediate types (score: 42-58) * Evening types (score: 16-41) |
