Background: Congenital fusion of cervical vertebra, most commonly known as Klippel-Feil syndrome, a rare deformity of spine which results from failed segmentation of the cervical somites while early embryonic development. Symptoms usually arises in adolescent or early adult phase of life due to increase in activity demands. Earlier this condition was managed usually using pharmaceutical management and rest.

Case Presentation: An 18 year old female students complaining of radiating pain, frequent headaches and difficulty in daily activities. 

Purpose: This study aims to find effectiveness of multimodal approach of physical therapy in managing symptoms.

Method: Patient was treated using active release technique, deep neck flexor training and neurodynamic mobilisation along with scapular and upper limb strengthening. Intervention was given for 6 weeks.

Result: Pain was significantly reduced. There was improvement seen in range of motion, deep neck flexor endurance and functional activity.

Conclusion: Patient showed improvement in deep cervical muscle endurance and activities in daily living. Pain reduced significantly. Multimodal approach was found to be effective.

Implication: This multimodal approach serves as an alternative to pure pharmacological management to address secondary complaints of Klippel-Feil syndrome.
