Immediate Effect of Chin Tuck Exercises on Craniovertebral Angle and Shoulder Angle Among Collegiates with Forward Head Posture

Forward head posture (FHP) is the forward movement of the head that is caused by improper postural awareness and often results in muscular imbalance that causes pain. The forward head posture is found to be influenced by Craniovertebral Angle (CV) and shoulder angle (SA) that in turn causes rounded shoulder. These biomechanical changes prove to be a hindrance in maintaining neutral head posture and affects the structural integrity. A sample size of 43 were taken according to the selection criteria and the FHP was assessed through plumb line. Double tape was used as markers at tragus of the ear, C7 vertebrae and acromion process. Photos were taken and analyzed using AUTOCAD 2017 software and the results were obtained. A positive association found between the pre and post test results for CV angle with P=0.0001(P<0.05) and no significant association between the pre and posttest for SA with P=0.2 (P>0.05). The craniovertebral angle can be altered with the chin tuck exercises but has no effect on the shoulder angle, hence having no influence over the rounded shoulders but has some effect over the forward head posture.

Comparison of three different types of exercises for selective contractions of supra- and infrahyoid muscles

Several exercise methods, such as the Shaker exercise, tongue press exercise, chin tuck against resistance (CTAR) exercise, and submandibular push exercise, have been introduced to strengthen the muscles involved in swallowing. In this study, we compared the effectiveness of the CTAR, submandibular push, and Shaker exercises for the induction of selective supra- and infrahyoid muscle contractions using surface electromyography (EMG). This study is a prospective non-randomized controlled study. Twenty-five healthy subjects and 20 patients experiencing swallowing difficulty were enrolled. During the three different types of exercises, the root mean square (RMS) values of the sternocleidomastoid (SCM), suprahyoid (anterior belly of the digastric and mylohyoid muscles), and infrahyoid (sternothyroid and thyrohyoid muscles) muscles were analyzed using surface EMG. Differences in the activity of swallowing muscles among the three different exercises were analyzed using one-way repeated measured analysis of variance. In terms of both the maximum and mean RMS values of the suprahyoid muscle, the submandibular push exercise showed a larger RMS value than the CTAR and Shaker exercises in healthy subjects (p < 0.05). In terms of both the maximum and mean RMS values of the suprahyoid muscle, the Shaker exercise and submandibular push exercise showed a larger RMS value than the CTAR exercise in patients with swallowing difficulty (p < 0.05). The submandibular push exercise may be effective as a swallowing muscle exercise owing to its superiority in inducing selective contractions of the supra- and infrahyoid muscles. The CTAR and Shaker exercises are also effective in this regard.

Effectiveness of Chin Tuck on Laryngeal Penetration: Quantitative Assessment

The effectiveness of the chin tuck maneuver is still controversial, despite being widely used in clinical practice. The chin tuck maneuver has been shown to be able to reduce or eliminate aspiration in a group of patients with a number of favorable conditions, but its effectiveness in preventing or managing penetration remains unclear. This study was designed to investigate whether the chin tuck maneuver is effective in reducing penetration. Images from a videofluoroscopic swallowing study (VFSS) taken from 76 patients with penetration were collected and reviewed retrospectively. The severity of penetration was assessed by the penetration ratio (ratio of the penetration depth to the length of the epiglottis) measured and calculated from the images in which the deepest penetration was observed. The penetration ratio was significantly decreased in the chin tuck posture compared with the ratio in the neutral position (p = 0.001). Significant reducing effect was observed in 26 (34.2%) out of 76 patients. When comparing other parameters of VFSS, residues in the vallecular and pyriformis sinuses were less severe in the effective group. Chin tuck significantly decreased residues in both effective and ineffective group. The results demonstrate that the chin tuck maneuver can reduce penetration, but its effectiveness is limited.

A PERBEDAAN PENGARUH MCKENZIE EXERCISE DAN CHIN TUCK EXERCISE TERHADAP FORWARD HEAD POSTURE MAHASISWA ILMU KOMUNIKASI

Latar Belakang : Penggunaan teknologi gadget menimbulkan kerugian bagi kesehatan, salah satunya gangguan postur. Postur yang tidak ergonomis seperti ini dilakukan dalam waktu yang lama dan berulang menyebabkan gangguan postur. Gangguan postur yang biasa terjadi adalah forward head posture.Tujuan : Untuk mengetahui apakah ada perbedaan pengaruh Mckenzie Exercise dan Chin Tuck Exercise terhadap Forward Head Posture pada mahasiswa ilmu komunikasi. Metode : Jenis penelitian ini adalah quasi experimental dengan pre test dan post test design two group dengan sampel berjumlah 20 orang yang ditentukan dengan purposive sampling. Sampel dibagi menjadi 2 kelompok yaitu kelompok 1 dengan perlakuan mckenzie exercise dan kelompok 2 dengan chin tuck exercise. Dilakukan selama 4 minggu dengan frekuensi 3 kali seminggu. Hasil : Uji hipotesis I dan II menggunakan paired sample t-test, kelompok I nilai p=0,001 (p<0,05), dan kelompok II nilai p=0,000 (p<0,05) yang menunjukan ada pengaruh pemberian mckenzie exercise dan chin tuck exercise terhadap forward head posture pada postur mahasiswa ilmu komunikasi. Hasil uji hipotesis III menggunakan uji independent sample t-test dengan nilai pada kelompok I p=0,493 (p>0,05) dan kelompok II p=0,494 (p>0,05) yang berarti tidak ada perbedaan pengaruh mckenzie exercise dan chin tuck exercise terhadap forward head posture pada postur mahasiswa ilmu komunikasi. Kesimpulan : Tidak ada perbedaan pengaruh mckenzie exercise dan chin tuck exercise terhadap forward head posture pada postur mahasiswa ilmu komunikasi. Saran : Bagi peneliti selanjutnya dapat menyediakan theraband sebanyak jumlah sampel untuk menghemat waktu penelitian.

Design and Development of the CTAR All-Star

The CTAR All-Star is a system consisting of a rubber ball, a pressure sensor, and a bluetooth transmitter paired with a cross-platform mobile application. The device is used as a rehabilitation tool for people with dysphagia in a similar fashion to the traditional chin tuck against resistance (CTAR) exercise by squeezing a ball between the chin and upper chest. The mobile device monitors and displays the pressure inside the ball on a real-time graph allowing the patient to follow exercise routines set by Speech-Language Pathologists. Additionally, the application stores exercise data that can be used to both monitor the patient's progress over time and provide objective data for future research purposes.
