Craniovertebral angle |
For measuring the angle, the reflective markers will be placed on the tragus of the ear and spinous process of the C7. The participant will be asked to stand and maintain her usual upright posture with her arms resting at the sides, and looking straight ahead. The photos will be captured by a digital camera. The camera will be positioned on a tripod 50 cm away from the participant. The axis of the lens of the camera will be placed orthogonal to the sagittal plane of the participant at the level of the shoulder. The photos will be taken repeatedly so that the participant was not exactly aware of the actual time of photography. The craniovertebral angle will be calculated by image. The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |

Forced Vital Capacity (FVC) |
Spirometry is the term for basic lung function tests that measure the amount of air exhaled and inhaled. There are three basic related measurements: volume, time, and flow. Spirometry is objective, non-invasive, sensitive to early changes and reproducible. With the availability of portable measuring devices, it can be performed almost anywhere and by anyone with the right training. The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |

Standing balance |
The Single Leg Stance Test (SLST) is used to assess static balance performance which requires the participant to stand barefoot on their right or left leg (donor's leg) and hold the contralateral leg in approximately 45 degrees of hip flexion and 90 degrees of knee flexion. They are instructed to cross their arms over the chest. The assessor uses a digital chronometer to measure the amount of time patients are able to stand on a single limb. The test ends when the patient's legs touch each other, the non-stance leg touches the floor, or the arms move from the starting position. This process is repeated three times with eyes open and three times with eyes closed. A two-minute rest period between attempts is considered to prevent fatigue. The average of the three trials is calculated separately. The participants will be assessed at baseline, one day before surgery (±1 day) and 4 weeks post-discharge (±3 days). |

Dynamic balance |
The Functional Reach Test (FRT) is widely used as a dynamic measure of balance and is a reliable measure of balance for clinical assessment of instability. Participants are asked to stand with their dominant side adjacent to a wall and raise their arm to shoulder height. They are then asked to reach out as far forward as possible while maintaining a firm base of support. A tape measure is attached horizontally to the wall, and the maximum reach distance is recorded as the farthest point of the third metacarpophalangeal joint from the initial (standing) position. In other words, the measures the maximum distance the participants can reach forward from a standing static position. Three trials are performed and the mean value is recorded. The participants will be assessed at baseline, one day before surgery (±1 day) and 4 weeks post-discharge (±3 days). |

Disability |
Howard Vernon developed the Neck Disability Index (NDI) in 1989. The Neck Disability Index is now a standard tool to measure self-reported disability due to neck pain. This tool has 10 items and each score from 0 to 5. 50 is the maximum score. To get a percentage score, the score obtained is multiplied by two. The average of all other items is then added to the completed items, if a respondent will not answer one or other question,. NDI is a commonly used tool to measure disability in individuals with forward head posture. The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |

Functional status |
The Functional Difficulties Questionnaire measures the functional status of patients following cardiac surgery, with special emphasis on upper extremity and trunk function in patients following median sternotomy. The questionnaire asks patients to rate the difficulty they would experience performing a series of 13 functional upper extremity and trunk tasks. Specifically, patients are required to place a mark along a 10-cm line, with anchors to the left and right of the line, respectively indicating 'no difficulty' and 'maximum difficulty'. For the activities that participants cannot complete when completing the questionnaire, they are required to recall they performed the tasks last time. The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |

Health related Quality of life |
Health related quality of life is assessed by SF-36, a common measure used to assess eight domains including physical functioning, role physical functioning, role emotional functioning, mental health, vitality, social functioning, bodily pain and general health. All scale or single-item measurements range in score from 0 to 100 and are managed by interview. The raw subscale scores are converted to 'norm-based' scores using published algorithms. Norm-based total physical and mental component scores are calculated from the raw subscale scores, with higher scores indicating better quality of life. A higher score in the SF-36 subdomains is associated with a high level of functioning and higher quality of life. The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |

Pain-related fear beliefs |
The TSK-11 is a widely used tool to measure pain-related fears related to movement and re-injury. It is an adaptation of the original 17-item instrument designed to assess fear of movement or re-injury excluding the 4 original reverse-scored items that were found to have small item-to-total score correlations. The adapted score is an 11-item tool that asks respondents to rate each item on a 4-point Likert scale, ranging from 1 (strongly disagree) to 4 (strongly agree). The TSK-11 is a reliable and valid measure of fear of movement or re-injury in patients with chronic pain. It has internal consistency, reliability and convergent validity with a Cronbach's a of 0.80 for the total score (Woby et al., 2005). The participants will be assessed at baseline, one day before surgery (±1 day), after surgery before discharge (7th postoperative day) (±1 day) and 4 weeks post-discharge (±3 days). |
