Carpal tunnel syndrome (CTS) is a very common compressive neuropathy involving the median nerve. The typical symptoms are paraesthesia, dysesthesia and loss of strength; in severe case, this compression deteriorates the sensorimotor control of the hand and interferes with the adjustment of the forces at the level of the fingers, thus affecting the components that are the basis of dexterity and control of fine movements. For these reasons, the CTS has repercussions on various activities of daily life, including writing skills. Word processing via PC and mobile device (touch-typing) require a fine control of the hand-wrist movement and of the opposition of the thumb, while in handwriting, gripping and gripping movements are carried out in a protracted manner. In modern society, present skills play a role of fundamental importance from an educational, professional and social point of view. The aim of the study is to describe the effects of carpal tunnel release (CTR) on handwriting and digital writing performance. We recruited patients suffering from carpal tunnel syndrome (CTS) who were candidates for CTR surgery and collected clinical and demographic data, including age, occupation, duration of symptoms and electromyography outcomes. The first trial session was carried out before surgery and the subsequent ones at 1, 2, 3, 4, 8 and 12 weeks after the CTR. These trials involved copying a 500-character paragraph by handwriting, personal computer (PC) and mobile device, for which a dedicate Google Colab web page was computed. We used as parameters the speed, expressed in words per minute (wpm), and the accuracy of copying, which was measured in number of errors (en). Moreover in each session the patient filled in the QuickDASH (Disabilities of the Arm, Shoulder, and Hand) questionnaire. We used the one-way anova to evaluate the change in the three performances and in the QuickDASH score in follow-up sessions. We used the two-way anova to detect a possible interactions between speed improvement and groups of variables, namely gender, writing frequency, schooling, diabetes, dysthyroidism and metabolic syndrome.Introduction and Objective
Materials and Methods
recent studies recognised metabolic abnormalities as additional factors in the development of rotator cuff (RC) tendinopathy. It has been hypothesised that the insertional area of this tendon is susceptible to degenerative changes due to intrinsic hypovascularization. The mechanisms underlying this process are not yet clear. In this study we attempted to confirm if larger lesions of the RC are related to impaired vasodilatatory response of the local circulation in conditions of “hemodynamic stress”. it was assumed that impaired vasal reaction to “hemodynamic stress” was a systemic condition. This phenomenon should therefore be not limited to the critical area of the tendon tear. Given this assumption post-ischemic vasodilation of brachial artery was studied through an echo-doppler (US) evaluation. 50 patients (mean 61 ± 4, range 50–65) all scheduled for surgical rotator cuff repair following a tendon tear, were enrolled. Three preoperative measurements of the brachial artery diameter before and after application of an ischemic band were collected. The size of the lesions was later assessed at the time of surgery. A statistical analysis was carried on to investigate the correlation between US assessment of brachial artery diameter and the corresponding size of the RC lesions. UCLA and ASES scores were also measured to assess clinical and functional outcomes.Introduction
