Effects of Cervical Deep Muscle Strengthening in a Neck Pain: A Patient with Klippel-Feil Syndrome

[Purpose] This study aimed to identify the effects of cervical deep muscle strengthening(CDS) on neck pain in a patient with Klippel-Feil syndrome (KFS). [Subjects and Methods]The subjects was a 39 year-old woman with neck pain and KFS that included incomplete blockvertebrae in the C2–3 segments and block vertebrae in the C6–7 segments. The subjectperformed an exercise program including cervical strengthening exercise (level 1) and CDSexercise (level 2) for 6 weeks. Neck pain intensity was measured using the visual analoguescale (VAS) and the pressure pain threshold (PPT). All measurements were obtained beforeand after the CDS exercise program. [Results] The VAS and PPT measurements decreased;range of motion in the cervical joint increased. [Conclusion] CDS exercises were effectiveinterventions for reducing neck pain in a patient with Klippel-Feil syndrome.Key words: Cervical deep muscle strengthening, Neck pain, Klippel-Feil syndrome
