Effects of Myokinetic Stretching Technique and Post Facilitation Stretching on Pain, Range of Motion, and Functional Disability in Patients With Cervical Radicular Pain

Cervical Radicular Pain

Cervical radicular pain (CRP) is a musculoskeletal condition characterized by neck pain radiating to the upper limb due to compression or irritation of cervical nerve roots. It significantly affects daily activities, cervical mobility, and overall quality of life. Conventional physical therapy focuses on reducing pain and improving function; however, there is limited evidence comparing the effectiveness of different stretching techniques used in clinical practice. This randomized controlled trial aims to compare the effectiveness of Myokinetic Stretching Technique (MST) and Post Facilitation Stretching (PFS) on pain intensity, cervical range of motion, and functional disability in patients with cervical radicular pain. A total of 70 participants with cervical radicular pain (\>4 weeks) will be randomly allocated into two groups: Group A (Myokinetic Stretching Technique Group) - receiving MST along with conventional therapy including hot pack application, cervical isometric exercises, neurodynamic gliding, and continuous cervical traction. Group B (Post Facilitation Stretching Group) - receiving Post Facilitation Stretching along with the same conventional therapy. The intervention will be conducted for 4 weeks, with 3 sessions per week on alternate days, each session lasting approximately 45 minutes. Outcome measures will include: Pain intensity assessed using the Visual Analogue Scale (VAS) Cervical range of motion measured using a goniometer Functional disability assessed using the Neck Disability Index (NDI) This study aims to determine the more effective stretching technique for reducing pain, improving cervical mobility, and enhancing functional outcomes, thereby supporting evidence-based physiotherapy practice in managing cervical radicular pain.

Cervical radicular pain (CRP) is a condition characterized by neck pain radiating to the upper limb due to compression or irritation of cervical nerve roots. It is commonly associated with reduced cervical range of motion, muscle tightness, and functional disability, significantly affecting daily activities and quality of life. Conservative physiotherapy interventions, including stretching techniques, play a key role in managing this condition. Among commonly used techniques, Myokinetic Stretching Technique(MST) and Post Facilitation Stretching (PFS) are widely applied to improve muscle flexibility, reduce pain, and enhance functional mobility. MST focuses on controlled contraction and gradual stretching to promote neuromuscular relaxation, whereas PFS involves maximal voluntary contraction followed by rapid passive stretching to achieve muscle lengthening. Despite their frequent use in clinical practice, there is limited comparative evidence regarding their effectiveness in patients with cervical radicular pain. This study is designed as a single-blinded, two-arm parallel randomized controlled trial. A total of 40 participants diagnosed with cervical radicular pain will be recruited using a convenience sampling technique. Participants will be randomly allocated into two groups using computer-generated randomization with a 1:1 allocation ratio. Allocation concealment will be ensured by an independent administrator, and outcome assessment will be performed by a blinded assessor. Both groups will receive conventional physiotherapy treatment consisting of hot pack application for 10 minutes, cervical isometric exercises (flexion, extension, lateral flexion, and rotation), neurodynamic gliding techniques, and continuous cervical traction. Participants in Group A will receive Myokinetic Stretching Technique, applied to the cervical musculature with emphasis on trapezius stretching combined with myofascial release techniques. Participants in Group B will receive Post Facilitation Stretching, involving strong voluntary contraction followed by rapid passive stretching of the targeted muscles. The intervention will be conducted over a period of 4 weeks, with 3 sessions per week on alternate days. Each treatment session will last approximately 45 minutes. Outcome measures will include pain intensity assessed using the Number Pain Rating scale Scale (NPRS), cervical range of motion measured using a goniometer, and functional disability assessed using the Neck Disability Index (NDI). Assessments will be conducted at baseline and after completion of the intervention. Data will be analyzed using SPSS software. Normality of data will be assessed using the Shapiro-Wilk test. Appropriate parametric or non-parametric tests will be applied for within-group and between-group comparisons. This study aims to provide evidence regarding the comparative effectiveness of Myokinetic Stretching Technique and Post Facilitation Stretching in improving pain, cervical mobility, and functional outcomes in patients with cervical radicular pain, thereby supporting evidence-based physiotherapy practice.
