Effects of Clinical Pilates Exercises in Patients With Chronic Nonspecific Neck Pain: a Randomized Clinical Trial
(Springer London Ltd, 2023) Picak, Gonca Sahiner; Yesilyaprak, Sevgi Sevi
Background Neck pain is a common musculoskeletal problem in adults. Clinical pilates exercises can be beneficial managing the pain and improving the risk factors. Aims The aim of this study was to investigate the effects of clinical pilates exercises on pain and disability, deep neck flexor endurance (DNFE), posture, cervical range of motion (CROM), and proprioception in patients with chronic nonspecific neck pain. Methods Fifty patients with chronic nonspecific neck pain were randomized into two groups. The clinical pilates exercise group (CPEG) received clinical pilates exercises for 6 weeks. The control group (CG) received posture education. Pain and disability, DNFE, forward head angle (FHA) and forward shoulder angle (FSA) degrees, CROM, and joint position error (JPE) were measured before and after 6 weeks. Results Clinical pilates exercises improved pain, Neck Disability Index (NDI), DNFE, posture, CROM (except extension), and JPE (p < 0.05). We found significant differences between CPEG and CG in the comparisons for the change of pain, NDI, DNFE, FSA, CROM (except extension), and JPE (except left rotation) (p < 0.05). NDI, FSA, and rotational JPE also improved in CG (p < 0.05). However, these improvements were significantly better in CPEG than CG (p < 0.05) except JPE in left rotation (p = 0.118). Conclusion In patients with chronic nonspecific neck pain, clinical pilates exercise is a safe and effective method to improve pain and disability, DNFE, posture, ROM, and proprioception.

Reliability and Validity of Eccentric Strength Measurement of the Shoulder Abductor Muscles Using a Hand-Held Dynamometer
(Churchill Livingstone, 2020) Karabay, Damla; Yesilyaprak, Sevgi Sevi; Picak, Gonca Sahiner
Objectives: To investigate the validity and intrarater and interrater reliability of eccentric strength testing of the shoulder abductors using a hand-held dynamometer (HHD) versus an isokinetic dynamometer. Design: Methodological. Setting: Research laboratory and athletic training room. Participants: Forty-seven asymptomatic shoulders of 25 participants were tested in 2 sessions by 2 physiotherapists. Main outcome measures: Eccentric strength of the shoulder abductors was measured from 120 degrees to 30 degrees scapular plane abduction using the HHD and isokinetic dynamometer. A gyroscope was used to validate the velocity. Spearman's rank correlation coefficients, intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were calculated. Results: The measurement protocol showed excellent intrarater (ICC[3,3] = 0.987, SEM = 2.59 Nm and MDC = 7.18 Nm) and interrater (ICC[3,3] = 0.990, SEM = 2.28 Nm and MDC = 6.32 Nm) reliability. HHD and isokinetic dynamometer measurements were strongly correlated (rho = 0.760, p < .001). Velocities during HDD testing were similar to those of the isokinetic dynamometer (30 degrees/s) (p > .050). Conclusions: Eccentric strength testing of the shoulder abductors using an HHD is a valid and reliable method that can be used for research and clinical purposes when an isokinetic dynamometer cannot be used.

Reliability of Different Protocols for Elbow Flexion and Extension Strength Measurement via Hand-Held Dynamometer
(Georg Thieme Verlag KG, 2025) Yesilyaprak, Sevgi Sevi; Ozden, Fatma; Karabay, Damla; Picak, Gonca Sahiner Picak
Objectives To investigate the reliability of elbow flexion and extension strength measurements via a hand-held dynamometer (HHD) in different positions and to determine the minimal detectable change (MDC). Design Reliability study. Methods Twenty healthy university students were evaluated at an exercise laboratory. Elbow flexion and extension strength were each measured by two physiotherapists in three different positions. Intra-class correlation coefficients (ICCs) were calculated to assess intra-rater reliability (ICC 3,3) and inter-rater reliability (ICC 3,3) and were used to calculate MDC. Results All measurement procedures have excellent intra- and inter-rater reliability scores in females (0.88-0.98) and males (0.81-0.95), except for moderate intra-rater reliability (0.72) for seated measurement of elbow flexion strength with the shoulder at 90-degree flexion in males. There is a systematic difference in inter-rater results for all flexion positions and intra-rater results for one flexion position in males (p<0.05). MDC95% ranged from 3.44 to 11.69 for intra-rater scores and from 6.19 to10.79 for inter-rater scores. Conclusions All procedures showed excellent reliability, except for moderate intra-rater reliability in seated measurement of elbow flexion strength with the shoulder at 90-degree flexion in males. However, elbow flexion measurement was prone to systematic differences in males. Muscle strength of the tested individual and testers should be considered.
