The purpose of this study is to determine the efficacy of laser acupuncture in alleviating CTS symptoms following flexor tendon repair in the hand.

This study holds significant importance for clinical practice, patient care, and research.

• Clinical Practice: It provides a potential framework for physical therapists to design targeted and effective interventions for laser acupuncture on CTS following flexor tendon repair in the hand.
• Patient Care: Improved rehabilitation outcomes can enhance patients' physical functionality, independence, and overall quality of life, addressing a critical gap in post-operative complications.
• Research Advancement: By contributing to the limited body of literature on laser acupuncture in this context, the study can stimulate further research and innovation in carpal tunnel syndrome following hand flexor tendon repair.

Inclusion Criteria:

• Adults aged 20-40 years who have undergone flexor tendon repair surgery.
• Patients who have undergone primary or secondary repair of flexor tendons in the hand at zone 4 (zone of carpal tunnel as it often be complicated by postoperative adhesions due to close quarters and synovial sheath of the carpal tunnel) (Fulchignoni C et al., 2020).
• Surgery occurred within a specific timeframe, often within 6-12 weeks prior to inclusion (Peters SE, Jha B, Ross M., 2021).
• Patient have clinical and electro diagnostic evidence of CTS.
• All patients enrolled to the study will have their informed consent.

Exclusion Criteria:

• Pre-existing neurological disorders.
• Systemic illnesses affecting nerve function (e.g., diabetes).
• Contraindications to laser therapy.
• Pregnancy or breastfeeding.
