Relationship between the mobility of medial longitudinal arch and postural control

Objective: The aim of this study was to analyze the relationship between the medial longitudinal arch mobility and static and dynamic balance. Methods: A total of 50 subjects (25 female, and 25 male; Mean age: 22.2 ± 1.3 years; BMI: 22.8 ± 3.8 kg/m2) were included in this study. The relative arch deformity (RAD) was calculated with both 10% and 90% weight bearing (WB). Static balance was evaluated with Single Leg Stance Test and dynamic balance with TechnoBody PK 200WL computerized balance device. Subjects were evaluated for goniometric measurements of lower extremity joints, leg dominance and leg-length discrepancy. Results: Bipedal dynamic balance was correlated with both feet length at 10% WB and 90% WB. There was a correlation between the dynamic balance on dominant foot and RAD value on the aspect of Medium Speed (r = −0.32, p = 0.02), Perimeter Length (r = −0.32, p = 0.02) and Anterior–Posterior Sway (r = 0.36, p = 0.01). Static balance was unaffected by RAD value when the visual system was eliminated. Conclusion: Our results suggest that decrease of arch mobility on the dominant foot is associated with posterior sway by causing knee or hip strategy and preventing ankle strategy even in small perturbations. The rate of deviation from the equilibrium point and the degree of total swaying increase when arch mobility decreases.

Musculoskeletal pain and its relation to individual and work-related factors: a cross-sectional study among Turkish office workers who work using computers

Objective . Office workers are commonly exposed to work-related musculoskeletal pain. This study investigated the individual and work-related risk factors linked to musculoskeletal pain and pain-related disability among Turkish office workers who work using computers. Methods. One-hundred and fifty office workers were included. Data were collected using an online survey with a combination of the Nordic musculoskeletal questionnaire, Oswestry disability index (ODI), neck disability index (NDI) and disabilities of the arm, shoulder, and hand questionnaire short-form (Q-DASH). The participants were divided into four subgroups: no pain (n = 26), lower back pain (n = 37), neck pain (n = 49) and upper-extremity pain (n = 38). Results. There were differences between subgroups in terms of the condition that feet touch the floor and the condition that the keyboard, mouse and wrist are in a straight line (p = 0.013 and p = 0.025, respectively). Working years was correlated with the ODI score (rho = 0.802, p = 0.041). There was also a significant correlation between the NDI score and working hours (rho = 0.415, p = 0.003), while Q-DASH was correlated with body mass index and working years (rho = 0.406, p = 0.014, and rho = 0.327, p = 0.043, respectively). Conclusions. Pain-related disability was associated with various risk factors such as physical inactivity, body mass index, working hours, working years and workplace ergonomics in the office workers

Background and Purpose

The effectiveness of Kinesio taping on playing-related pain, function and muscle strength in violin players: A randomized controlled clinical trial

Objectives: This study aimed to investigate the effectiveness of Kinesio taping (KT) on playing-related pain, upper extremity and hand function, grip and pinch strength in violin players. Design: Randomized controlled trial. Setting: Faculty of health sciences. Participants: One hundred seventeen participants who were professional violinists for at least two years (82 women; mean age, 22.76 +/- 3.87 years) were randomized to receive either therapeutic tape application (KT group), a sham tape application (placebo group), or no application (control group) for one week. Outcome measures: The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) in one week. The secondary outcomes were the Visual Analogue Scale (VAS), the Purdue Pegboard Test, grip and pinch strength. Outcome measures were performed at baseline, immediately after the intervention, and one week later (follow-up). Participants were asked to play the "Violin Concerto No.2, Op.35 (Rieding, Oskar)"; pre-and post-performance pain and grip and pinch strength were assessed. Results: The overall group-by-time interaction was not significant for DASH, but the improvement in the mean VAS-playing was slightly better in the KT group than in others (p < 0.05). The mean post-performance VAS-playing remained similar in the KT group while slightly increasing in the other groups (p < 0.05). In addition, a decrease in the mean post-performance grip strength of the left hand was significantly lower in the KT group than in the other groups (p < 0.05). Conclusions: Violin players receiving an application of KT represented minor improvements in playing-related pain, and post-performance pain intensity and grip strength of the left hand slightly remained after 1 week kT application. The possible post-performance effect of the tape on the pain intensity and grip strength must also be considered because KT can be used during the performance. (c) 2021 Elsevier Ltd.
