Balancing the Load: Perceived Stress, Burnout, and Coping in Irish Athletic Therapy Students

Siobhán O’Connor, Maftei Ionut Tarmure, and Sinéad O’Keeffe

Prolonged stress, poor coping skills, and a lack of engagement in self-care activities can contribute to burnout. We investigated perceived stress, burnout, and coping in Irish athletic therapy students. Moderate stress (20.5 ± 6.7), personal (57.5 ± 20.4), and work-related burnout (52.7 ± 18.1), along with low resilient coping (13.7 ± 2.4), overall (46.0 ± 15.6) and client-related (26.7 ± 17.2) burnout were noted. Women athletic therapy students presented with higher overall (r = .17, p = .04), personal (r = .20, p = .02), and work-related (r = .17, p = .03) burnout and lower resilient coping (r = .20, p = .02). Students working longer hours in employment had higher work- (r = .19, p = .04) and client-related (r = .19, p = .04) burnout scores. Thus, interventions to alleviate stress and burnout and enhance coping skills in students embarking on their career are urgently needed. Targeted strategies for women and those working a high number of hours in external employment are particularly required.

Minimizing Running Load via Gentle Heel Strike Techniques: A Gait Modification Study

Wei Shen, Zongchen Hou, Patrick C. Wheeler, and Daniel T.P. Fong

Introduction: Running overuse injuries are among the most common running-related musculoskeletal injuries. Modifying gait has been recognized as an effective strategy for preventing running overuse injuries. This study investigates whether gentle heel strike (GHS) running decreases the impact loading rate during 30-minute runs in healthy participants. Methods: In this prospective cohort interventional study, 20 male participants underwent gait modification in a controlled laboratory setting, with the goal of reducing heel impact through real-time visual feedback. Comprehensive measurements, including plantar contact, force, pressure, and detailed kinetic and kinematic analyses, were employed to assess changes in gait dynamics. Results: GHS significantly shifted plantar pressure, reducing heel forces and increasing forefoot load. Mean heel force decreased by 0.32 (0.1) body weight (BW) and heel pressure reduced by 0.1 kPa/BW. Although peak vertical ground reaction force and anterior–posterior ground reaction force did not change significantly across the entire stance phase, early stance vertical ground reaction force (7%–12% of the gait cycle) was reduced, leading to the disappearance of the vertical impact peak. Vertical impact peak dropped from 1.45 (0.23) to 1.27 (0.25) BW. Significant reductions were also seen in the vertical instantaneous loading rate, which decreased from 68.32 (14.20) to 46.77 (13.95) BW/s, and the vertical average loading rate, which fell from 54.96 (14.38) to 38.84 (12.62) BW/s (P < .001). Discussion: GHS has the potential to modify running mechanics by redistributing plantar pressure and diminishing heel impact force. This reduction in heel impact force could lead to a change in landing pattern anteriorly and a decrease in loading rates, potentially reducing the risk of running overuse injuries. Conclusion: Visual biofeedback-guided GHS is feasible in healthy participants, and it effectively reduces the loading rate during running for 30 minutes.

Comparing Nerve Versus Muscle Wide-Pulse High-Frequency Electrical Stimulation for Maximal and Submaximal Efforts

Álvaro de Almeida Ventura, Denis César Leite Vieira, Luis André de Oliveira Soares, Júlia Aguillar Ivo Bastos, Nicolas Babault, Martim Bottaro, and João Luiz Quagliotti Durigan

Purpose: The effectiveness of neuromuscular electrical stimulation hinges on the evoked torque level, which can be attained through either conventional (CONV) or wide-pulse high frequency (WPHF). However, the best electrode placement is still unclear. This study adopted a crossover design to compare the effects of WPHF applied to the tibial nerve trunk (N-WPHF) or muscle (M-WPHF) with CONV in healthy participants. Methods: A total of 30 participants (age: 22.4 [4.5]) were involved in 4 sessions. During each session, participants performed: 2 maximal voluntary contractions, 2 contractions at maximal evoked torque, and 2 contractions at submaximal evoked torque at 20% maximal voluntary contraction. Neuromuscular electrical stimulation intensity-evoked torque, efficiency, and discomfort were measured in maximal and submaximal conditions. Statistical analyses were conducted using a 1-way mixed-model analysis of variance with repeated measures. Results: N-WPHF and M-WPHF showed higher evoked torque than CONV (P = .002 and P = .036) and greater efficiency than CONV for maximal evoked torque (P = .006 and P = .002). N-WPHF induced higher efficiency than M-WPHF and CONV for submaximal evoked torque (P = .004). Higher discomfort was observed for both N-WPHF and M-WPHF for submaximal evoked torque compared with CONV (P = .003 and P < .001). Conclusion: Our results suggest that WPHF applied at either the nerve or muscle could be the best choice for the maximal condition, whereas nerve application is preferred for the submaximal condition.

Effects of Instrument-Assisted Soft Tissue Mobilization and Extracorporeal Shock Wave Therapy in Individuals With Lateral Elbow Pain: A Randomized Single-Blind Clinical Trial

Hasan Gercek, Bayram Sonmez Unuvar, Onur Aydoğdu, Ozlem Akkoyun Sert, and Zubeyir Sari

Context: In lateral elbow pain (LEP), it is important to improve pain, grip strength, and function. The aim of this study is to compare the effects of Instrument-Assisted Soft Tissue Mobilization (IASTM) and extracorporeal shock wave therapy (ESWT) methods on pain, grip strength, and function in LEP. Design: Randomized single-blind clinical trial. Methods: Forty-eight adults with LEP were randomly assigned to the IASTM, ESWT, and control groups. Home exercise consisting of special static stretching and eccentric strengthening exercises was given to the control group. The ESWT group received a total of 8 sessions of ESWT in addition to home exercise. The IASTM group received a total of 8 sessions of IASTM in addition to home exercise. The visual analog scale for pain, hydraulic hand dynamometer for grip strength, and Patient-Rated Tennis Elbow Evaluation scale for functionality were used for assessment. Data were collected at baseline, after intervention, and at 4-weeks postintervention. Results: At the end of the treatment and the 4-week follow-up, a decrease in pain scores and improvement in muscle strength and functionality was detected in all 3 groups (P < .001). IASTM applications were more effective than ESWT and control groups in reducing pain both after application and at follow-up (P < .001), whereas ESWT application was also effective compared with the control group (P < .001). IASTM applications were more effective than the ESWT and control groups in reducing Patient-Rated Tennis Elbow Evaluation total scores both after the applications and follow-up (P < .001). IASTM was more effective in grip strength than ESWT and control groups (P < .001). Conclusion: It was determined that IASTM and ESWT treatments were effective in reducing pain and increasing grip strength and functionality in both the short and long term in patients with LEP. It was determined that IASTM treatment was superior to ESWT treatment in reducing pain and improving grip strength and functionality.

Persian Version of the Modified Constant Score in Overhead Athletes: A Reliability and Validation Study

Fariba Jafari, Leila Abbasi, and Alireza Motealleh

Context: Shoulder impingement syndrome (SIS) is the most common shoulder injury among overhead athletes. The Constant score (CS) is a combined scoring system to evaluate functional status of the shoulder in patients with shoulder pain. Design: Cross-sectional study. Methods: Cultural adaptation of the Persian version of CS was conducted using Beaton’s guideline. Sixty-three overhead athletes (23.57 [7.50] y old) with SIS completed the final version for psychometric assessment. After 5 to 7 days, a group of 33 patients completed the Persian CS again to assess test—retest reliability. Internal consistency, floor/ceiling effects, and item-total correlation were evaluated in patients with SIS. Concurrent validity was assessed through comparison with the disability of the arm, shoulder, and hand questionnaire scores. Twenty-five healthy athletes (31.80 [7.32] y old) participated for determining discriminant validity. Results: The Persian CS demonstrated good test–retest reliability, with subjective and objective intraclass correlation coefficients of .79 and .80, respectively. The internal consistency was satisfactory (Cronbach alpha = .74). No ceiling or floor effects were noted. The Pearson correlation coefficient between CS and disability questionnaire was −.68. The mean total score for patients was 67.02, while for the healthy group was 96.99 (P = .000). The standard error of measurement was 1.51 for patients and 0.7 for healthy group. The smallest detectable change was 16.95 for patients and 5.71 for healthy group. Conclusion: The translation and cross-cultural adaptation of CS into Persian were successful. The Persian version demonstrates sufficient reliability and validity to evaluate shoulder function in overhead athletes with SIS.

Validity and Reliability of the Spanish Version of the Athlete Psychological Strain Questionnaire

Jorge García-Rubio, Daniel González-Devesa, José Carlos Diz-Gómez, and Ayán-Pérez Carlos

Context: This study aims to provide data on the reliability and validity of an adapted Spanish version of the Athlete Psychological Strain Questionnaire (APSQ) when administered to Spanish athletes. Design: A cross-sectional study was developed. Methods: Data were collected from 128 athletes (males n = 71; females n = 57). The tools used in this study were the APSQ; Kessler Psychological Distress Scale; and Depression, Anxiety, and Stress Scales. The intraclass correlation coefficient was used to determine relative reliability, whereas standard error measurement and minimal detectable change were used to evaluate absolute reliability. Bland–Altman plots were employed to assess test–retest agreement and potential systematic bias. Results: Data indicate that the Spanish version of the APSQ demonstrated satisfactory internal consistency (α: .77–.85) and generally fair to good test–retest reliability (intraclass correlation coefficient: .702; 95% CI, .602–.780). Significant associations were found between the APSQ Spanish version and the Depression, Anxiety, and Stress Scales (ρ = .64–.82), with fair to good agreement, whereas fair to moderate levels of agreement were established between the APSQ Spanish version and the Kessler Psychological Distress Scale (ρ = .53–.75). Conclusions: These results provide preliminary evidence supporting the use of the APSQ Spanish version for mental health screening among Spanish athletes. However, the lack of absolute reliability raises concerns about its utility for assessing the effects of interventions aimed at improving mental well-being.
