Abstract
Aim. The aim of this study is to investigate the relationship between shoulder external rotation range of motion (ER ROM) and performance on the Y-Balance Test in young cricketers. Specifically, the study seeks to determine whether greater shoulder external rotation is associated with improved dynamic balance, which is crucial for cricket performance, particularly in movements like throwing and bowling. The research aims to provide insights that may help guide training and injury prevention strategies in young athletes.
Methods. A total of 50 cricketers were selected based on defined inclusion and exclusion criteria. The active ROM of shoulder external rotation on the dominant side was measured using a goniometer. Participants performed the three directional movements of the YBT using non-instrumented floor markings.
Findings. The study analyzed the relationship between Y-Balance Test (YBT) performance and shoulder external rotation range of motion (ROM) in young cricketers. The mean medial component of YBT was 80.42, with a weak positive correlation (r = 0.048, p = 0.82). The superolateral component had a mean of 59.18 and a weak negative correlation (r = −0.284, p = 0.16). The inferolateral component showed a moderate negative correlation (r = −0.365, p = 0.073) with a mean of 74.98. Shoulder external rotation ROM had a mean of 88.12, but no significant correlations were found.
Conclusion. Among the three YBT components, only the medial component demonstrates a positive correlation with shoulder external rotation on both the dominant and non-dominant sides. Conversely, the superolateral and inferolateral components exhibit a negative correlation.
Key words

Abstract
Introduction. The condition known as cyclist neck syndrome, characterized by fatigue and the inability of the neck muscles to support the head, often results from prolonged cycling in an improper position. This repetitive strain on the neck extensor muscles commonly leads to reduced range of motion, pain, and impaired performance.
Aim of the study. To assess the effectiveness of neck extensor stretching and strengthening exercises in reducing symptoms of cyclist neck syndrome, improving range of motion, and enhancing overall neck function.
Materials and methods. A total of 50 participants diagnosed with cyclist neck syndrome were randomly selected. Inclusion criteria included individuals aged 20–50 years, cycling at least five times per week, and covering a minimum of 75 km per ride. Exclusion criteria encompassed a history of neck surgery, traumatic neck pain, spinal instability, rheumatological conditions, and recent neck interventions. Participants were divided into two groups of 25: Group A received conventional treatment plus neck extensor stretching and resistance training; Group B received only conventional treatment. Pre-treatment data were collected using the Numerical Pain Rating Scale (NPRS) and cervical range of motion (ROM) for flexion and extension, assessed with Kinovea software. The intervention lasted 4 weeks, with 4 sets per session, 15 repetitions per set, conducted 3 times per week.
Results. Post-treatment mean NPRS score for Group A was 2.16, compared to 5.2 for Group B. Group A showed improved post-treatment cervical ROM in flexion (67.04) and extension (53.4), whereas Group B showed 46 and 47.4, respectively. These results indicate that Group A achieved greater reductions in pain and better functional outcomes.
Conclusion. The findings support that incorporating neck extensor stretching and resistance training significantly improves symptoms and neck function in individuals with cyclist neck syndrome.

Sundar Rajan M S et al. – Effectiveness of Mulligan “MWM” versus Spencer technique on functional ability in subjects with adhesive capsulitis of the shoulder joint –  Fizjoterapia Polska 2025; 25(2); 54-59

Abstract
Background. Frozen shoulder, or adhesive capsulitis, is characterized by pain and progressive loss of both active and passive shoulder range of motion due to capsular contracture and fibrosis. The Spencer technique focuses on mobilizing the glenohumeral and scapulothoracic joints. The Mulligan technique combines active movement with passive accessory mobilization to achieve pain-free motion by restoring impaired accessory glide.
Objective. To evaluate the effectiveness of Mulligan “MWM” versus the Spencer technique in patients with adhesive capsulitis of the shoulder joint using range of motion (ROM) and the Shoulder Pain and Disability Index (SPADI).
Methods. Forty subjects meeting the inclusion and exclusion criteria were selected. The procedure was explained in detail, and informed consent was obtained before initiating the study. Pre- and post-test values were measured using ROM and SPADI. Participants were divided into two groups: Mulligan “MWM” with exercise (n = 20), and the Spencer technique with exercise (n = 20). Both groups received arm circles, pendulum stretch, towel stretch, wand exercise, wall climbing, and upper body stretch, three days a week for six weeks (2 sets of 10 repetitions with a 10-second hold).
Results. The data were statistically analyzed using an unpaired t-test. The Mulligan “MWM” group showed significantly greater improvement (p < 0.01) in pain reduction and functional ability compared to the Spencer technique, as measured by ROM and SPADI.
Conclusion. Mulligan “MWM” is more effective than the Spencer technique, when combined with exercise, in reducing pain and improving functional ability in individuals with adhesive capsulitis of the shoulder joint.
