Employee burnout: the dark side of performance-driven work climates

Purpose: The purpose of this study is to explore the role of “overtime norms” as a mediator between performance-driven work climates and employee burnout. This study also examines in-role performance and work engagement as moderators between high-performance climates and burnout. Design/methodology/approach: A snowball sample of 214 full-time working adults from the United States participated via an online survey. Data were analyzed using SmartPLS and conditional process analysis. Findings: Results from conditional process analyses suggest (1) performance-driven climates are positively related to burnout, (2) overtime norms mediate the relationship between performance-driven climates and burnout, and (3) in-role performance and work engagement moderate that relationship such that highly competent and engaged employees are less prone to stress and burnout. Practical implications: These results highlight the dangers of performance-driven work climates on employee well-being. Trends toward extended work hours which can be exacerbated by technological advancements inevitably come at a cost. Managers and organizations should be careful not to prioritize work life over non-work life. Originality/value: This study contributes to the literature by identifying overtime norms as a mediator in the performance-driven work climate–burnout relationship. This study also identifies in-role performance and work engagement as resources that can reduce burnout

Randomized Controlled Trial of Intense Therapeutic Ultrasound for the Treatment of Chronic Plantar Fasciitis

Category: Sports Introduction/Purpose: Initial treatment of plantar fasciitis (PF), consisting of anti-inflammatories, stretching and in-shoe orthosis (heel pad, heel wedge, or arch support), leads to symptomatic resolution in over 90% of patients but takes 3-6 months. This study was conducted to test the effectiveness of a minimally invasive modality, intense therapeutic ultrasound (ITU), in accelerating the healing of chronic plantar fasciitis (PF). ITU uses high-frequency high-intensity focused ultrasound to create small thermal injury zones inside soft tissue without damage to surrounding structures. ITU has been shown to initiate a tissue repair cascade and promote collagen generation in dermal and musculoskeletal tissue and is FDA approved for use in non-surgical brow lifts [1,2]. The goal of this study was to determine if ITU when combined with standard therapy could speed the healing of chronic PF. Methods: 47 patients with chronic (greater than 3 months) heel pain due to PF were randomized to standard therapy (anti- inflammatory pills, stretching, and gel heel cups) plus ITU (“ITU”, n=33) or standard therapy plus sham ITU (“control”, n=14) groups. ITU treatments were administered at enrollment and two-weeks later using a custom 3.3 MHz therapeutic ultrasound system (Guided Therapy Systems, Mesa, AZ). Sham treatment utilized the same protocol but with the energy set to 0 Joules. Treatment effect was assessed at 2, 4, 6, and 12 weeks after the initiation of treatment using diagnostic ultrasound and patient reported outcomes (PROMIS physical function computer adaptive test, PROMIS global health, Foot Function Index pain subscale, and a non-validated heel pain specific questionnaire). Ultrasound images were analyzed to determine the size of lesions within the PF. Both the sonographer and the study coordinator administering the patient reported outcome instruments were blinded to group assignment. Results: 38 patients completed the 12 week study (ITU: n=37, Control: n=11.). The ITU group reported a significantly greater reduction in heel pain scores [Mean 8.27, SD 4.69, P=0.027] compared to the control group [Mean 2.25, SD 5.92] (Figure 1). Ultrasound imaging showed an 81% decrease in perifascial lesion size in the treatment group, compared to a 26% increase in lesion size in the control group (Figure 2). Conclusion: Preliminary results of this clinical study of noninvasive ITU for the treatment of chronic PF showed that ITU treatment as compared to sham control lead to a larger and more rapid reduction of heel pain and perifascial lesion size. ITU holds promise as a potential therapy to accelerate the healing of chronic plantar fasciiti
