Effects of Sprinter and Skater on Text Neck Syndromes

This study will explore the combined effects of sprinter and skater synergy exercises on pain, muscle activation, and postural alignment in individuals with Text Neck Syndrome (TNS). TNS is characterized by forward head posture, neck pain, and muscle imbalance resulting from prolonged use of smartphones and computers. Its prevalence has increased rapidly, particularly among adolescents and young adults who spend long hours on digital devices. The study aims to evaluate Coordinated Locomotor Training (CLT), using sprinter and skater synergy movement patterns, as a novel intervention for managing TNS. These dynamic, whole body movement patterns are designed to promote coordinated muscle activation, improve postural control, and enhance neuromuscular coordination. A randomized controlled trial design will be used, with participants assigned to either an intervention group receiving CLT based training or a control group receiving lifestyle and ergonomic advice only. Outcome measures will include pain intensity, postural alignment measured by craniovertebral angle, muscle activation, and quality of life. The findings will help determine whether synergy based movement training offers a more effective alternative to conventional physiotherapy for TNS management.

About this study

Detailed Description (5.2) - Copy Paste:

Background: Digital technology has become a vital part of daily life, changing the way people work, communicate and relax and resulting in unprecedented levels of screen time for all generations. Handheld smart devices, such as smartphones, tablets and computers, have become an essential part of the professional, academic and social lives. But with this technological improvement there has been a significant increase in technology-related musculoskeletal disorders. Neck pain, particularly, is one of the biggest causes of disability globally, especially among young adults and people who work in an office environment performing prolonged sitting postures .The cervical structures may be affected by mechanical stress caused by the prolonged flexed position held while using a smartphone and computer, also known as Text Neck Syndrome (TNS), and there may be a shift in neuromuscular control. New epidemiological evidence in recent years reveals that over 4 hours of digital device use has a detrimental effect on the prevalence of FHP, cervical discomfort, and cervical functional capacity among people. This was reflective of the fact that there has been a change in human behaviors in the digital age from acute injury to chronic postural dysfunction.

Objectives: To evaluate the effect of the combination of synergy exercises (sprinting and skater) on the intensity of pain, muscle activation and posture in people suffering from Text Neck Syndrome (TNS). Secondary objectives include determining which technique shows significantly greater improvement and providing evidence-based recommendations for physiotherapy practice in Pakistan.

Methodology Research type The study design for this research was randomized clinical trials. Study population People of both genders aged 25-45 years with Text neck syndrome Study setting Habib Bank of Pakistan, National Bank of Pakistan, Meezan bank Duration of study Study was completed after the approval of synopsis within 4 months. Sample technique Consecutive sampling technique were used for sampling. Sample size The sample size of 50 participants (25 per group) were included calculated by using G power app.

Allocation and randomization Randomization was carried out using a computer generated random number generator to ensure unbiased group allocation. At the start of the study, a sequence of random number was generated and used to assign participants to either Group A or Group B. As participants were enrolled, they were allocated to groups according to this predefined sequence, ensuring that each participant had an equal chance of being placed in either group.

Intervention Group A : Coordinated Locomotor Training (CLT) The CLT protocol was based on Janda's tonic phasic muscle theory, aimed to restore reciprocal muscle activation patterns and postural balance Duration: 8 weeks Frequency: 3 sessions per week Session Length: 40 minutes Table 1 : Session Phases Phase Repetitions / Sets Description Warm-up Hot pack: 10 minutesChin tuck: 2 sets × 10 reps (10 sec hold)Scapular retraction: 2 sets × 10 reps An electric hot pack was applied for approximately 10 minutes prior to intervention to enhance tissue extensibility and circulation. This was followed by chin tuck exercises for deep neck flexor activation and scapular retraction exercises to promote postural muscle engagement.

Main CLT Phase 2 sets × 10 repetitions per side Alternating Sprinter and Skater synergy exercises performed in supine, sitting, and standing positions to activate deep neck flexors, rhomboids, and serratus anterior while inhibiting upper trapezius and pectoralis major/minor.

Integration Phase 2 sets × 10 repetitions Sequential Sprinter → Skater → Sprinter movement patterns to improve interlimb coordination and neuromuscular control.

Relaxation / Cool Down 5 breathing cycles Gentle breathing and relaxation exercises to reduce muscle tension and promote recovery.

Participants also perform brief home based micro sessions (5-8 minutes) during work hours to maintain postural endurance.

Group B: control group: The control group was received a structured program of conventional physiotherapy exercises focusing on improving neck stability, activating postural muscles, and reducing muscle tightness. Conventional protocols sued "deep cervical flexor training, scapular strengthening, and stretching exercises" that significantly improve pain, posture, and functional outcomes in individuals with neck pain and forward head posture.

Intervention Parameters

  • Duration: 8 weeks
  • Frequency: 3 sessions per week

This was followed by chin tuck exercises for deep neck flexor activation and scapular retraction exercises to promote postural muscle engagement.

Cervical Stabilization Exercises 2 sets × 10reps (10 sec hold) Deep neck flexor exercises (chin tuck in supine and sitting positions) to improve cervical stability and correct forward head posture.

Scapular Strengthening 2 sets × 10 reps Scapular retraction and prone horizontal abduction exercises targeting middle and lower trapezius and rhomboids to improve postural control.

Stretching Exercises 2 sets× 10 reps per muscle (20 sec hold) Static stretching of upper trapezius, levator scapulae, and pectoralis muscles in sitting to reduce muscle tightness and improve flexibility.

Treatment and study plan

Coordinative locomotor training group

Other

Participants allocated to the Coordinated Locomotor Training (CLT) group were received an intervention based on Janda's tonic-phasic muscle theory, which aimed to restore reciprocal muscle activation patterns, improve postural alignment, and enhance neuromuscular coordination by facilitating coordinated movement synergies. The intervention were administered over 8 weeks, with three supervised sessions per week, and each session lasts for approximately 25-30 minutes.

Each treatment session begun with a warm-up phase, during which an electric hot pack wase applied to the cervical and upper thoracic region for approximately 10 minutes to increase local circulation, reduce muscle stiffness, and improve soft tissue extensibility. Following thermotherapy, participants performed chin tuck exercises (2 sets of 10 repetitions with a 5-10-second hold) to activate the deep cervical flexor muscles, followed by scapular retraction exercises (2 sets of 10 repetitions) to facilitate activation of the

Control Group

Each treatment session were begin with a warm-up phase, during which an electric hot pack were applied to the cervical and upper thoracic region for approximately 10 minutes to increase local circulation, reduce muscle stiffness, and improve soft tissue extensibility. This will be followed by chin tuck exercises (2 sets of 10 repetitions with a 5-10-second hold) to facilitate activation of the deep cervical flexor muscles and scapular retraction exercises (2 sets of 10 repetitions) to activate the scapular stabilizers and promote optimal postural alignment.

The cervical stabilization phase was included deep cervical flexor exercises performed in both supine and sitting positions, with participants completing 2 sets of 10-12 repetitions, maintaining each contraction for 5-10 seconds. These exercises ere intended to improve cervical stability, enhance endurance of the deep neck flexor muscles, and correct forward head posture.

The scapular strengthening phase was consisted of scapular re
