Factors influencing return to work experienced by people with acquired brain injury: a qualitative research study

Purpose. To describe the factors experienced by adults with moderate-to-severe acquired brain injury (ABI) as either limiting or facilitating during the process of return to work (RTW) in order to give an advice about the vocational rehabilitation process. Methods. A qualitative study was performed. Twelve adults who were working before acquiring traumatic or non-traumatic brain injury (2–3 years earlier) participated. The experiences were gathered by semi-structured interviews. The International Classification of Functioning, Disability and Health was used as a theoretical framework for the interviews and the analysis. Results. The most common limiting factor was tiredness. The most common facilitating factors were the will to RTW, the ongoing recovery and the knowledge and support of the employer, colleagues, occupational physician and occupational specialist. Conclusions. Different aspects were experienced as being important during the process of RTW after ABI. These aspects should be kept in mind during the process of RTW to make the outcome as successful as possible. It is advised to pay special attention to the recovery opportunities of an individual, to inform the employer, colleagues, occupation physician and the occupational specialist about ABI, and to support people with ABI for long time periods. An important role can be played by the rehabilitation centre.
Warm-Up Exercises May Not Be So Important for Enhancing Submaximal Running Performance

Abstract Takizawa, K, Yamaguchi, T, and Shibata, K. Warm-up exercises may not be so important for enhancing submaximal running performance. J Strength Cond Res 32(5): 1383–1390, 2018—The purpose of this study was to determine an appropriate warm-up intensity for enhancing performance in submaximal running at 90% vV[Combining Dot Above]O2max (it assumes 3,000–5,000 m in track events). Seven trained male university athletes took part in this study (age: 21.3 ± 2.1 years, height: 169.3 ± 4.7 cm, body mass: 58.4 ± 5.6 kg, V[Combining Dot Above]O2max: 73.33 ± 5.46 ml·kg−1·min−1). Each subject ran on a treadmill at 90% vV[Combining Dot Above]O2max until exhaustion after 1 of 4 warm-up treatments. The 4 warm-up treatments were no warm-up, 15 minutes running at 60% vV[Combining Dot Above]O2max, at 70% vV[Combining Dot Above]O2max, and at 80% vV[Combining Dot Above]O2max. The running performance was evaluated by time to exhaustion (TTE). V[Combining Dot Above]O2, and vastus lateralis muscle temperature were also measured. There were no significant differences in TTE among the warm-up exercises (p > 0.05). V[Combining Dot Above]O2 in no warm-up showed slower reaction than the other warm-up exercises. Regarding, the vastus lateralis muscle temperature immediately after warm-up, no warm-up was significantly (p < 0.01) lower compared with the other warm-up exercises. Our results suggested that submaximal running performance was not affected by the presence or absence of a warm-up or by warm-up intensity, although physiological changes occurred.
Four Weeks of Nordic Hamstring Exercise Reduce Muscle Injury Risk Factors in Young Adults

Abstract Ribeiro-Alvares, JB, Marques, VB, Vaz, MA, and Baroni, BM. Four weeks of Nordic hamstring exercise reduce muscle injury risk factors in young adults. J Strength Cond Res 32(5): 1254–1262, 2018—The Nordic hamstring exercise (NHE) is a field-based exercise designed for knee-flexor eccentric strengthening, aimed at prevention of muscle strains. However, possible effects of NHE programs on other hamstring injury risk factors remain unclear. The purpose of this study was to investigate the effects of a NHE training program on multiple hamstring injury risk factors. Twenty physically active young adults were allocated into 2 equal-sized groups: control group (CG) and training group (TG). The TG was engaged in a 4-week NHE program, twice a week, 3 sets of 6–10 repetitions; while CG received no exercise intervention. The knee flexor and extensor strength were assessed through isokinetic dynamometry, the biceps femoris long head muscle architecture through ultrasound images, and the hamstring flexibility through sit-and-reach test. The results showed that CG subjects had no significant change in any outcome. TG presented higher percent changes than CG for hamstring isometric peak torque (9%; effect size [ES] = 0.27), eccentric peak torque (13%; ES = 0.60), eccentric work (18%; ES = 0.86), and functional hamstring-to-quadriceps torque ratio (13%; ES = 0.80). The NHE program led also to increased fascicle length (22%; ES = 2.77) and reduced pennation angle (−17%; ES = 1.27) in biceps femoris long head of the TG, without significant changes on muscle thickness. In conclusion, a short-term NHE training program (4 weeks; 8 training sessions) counteracts multiple hamstring injury risk factors in physically active young adults.
Reliability and validity of Short Form 36 Version 2 to measure health perceptions in a sub-group of individuals with fatigue

Purpose. To determine the validity and reliability of Short Form 36 Version 2 (SF36v2) in sub-groups of individuals with fatigue. Method. Thirty subjects participated in this study, including n == 16 subjects who met case definition criteria for chronic fatigue syndrome (CFS) and n == 14 non-disabled sedentary matched control subjects. SF36v2 and Multidimensional Fatigue Inventory (MFI-20) were administered before two maximal cardiopulmonary exercise tests (CPETs) administered 24 h apart and an open-ended recovery questionnaire was administered 7 days after CPET challenge. The main outcome measures were self-reported time to recover to pre-challenge functional and symptom status, frequency of post-exertional symptoms and SF36v2 sub-scale scores. Results. Individuals with CFS demonstrated significantly lower SF36v2 and MFI-20 sub-scale scores prior to CPET. Between-group differences remained significant post-CPET, however, there were no significant group by test interaction effects. Subjects with CFS reported significantly more total symptoms (p < 0.001), as well as reports of fatigue (p < 0.001), neuroendocrine (p < 0.001), immune (p < 0.01), pain (p < 0.01) and sleep disturbance (p < 0.01) symptoms than control subjects as a result of CPET. Many symptom counts demonstrated significant relationships with SF36v2 sub-scale scores (p < 0.05). SF36v2 and MFI-20 sub-scale scores demonstrated significant correlations (p < 0.05). Various SF36v2 sub-scale scores demonstrated significant predictive validity to identify subjects who recovered from CPET challenge within 1 day and 7 days (p < 0.05). Potential floor effects were observed for both questionnaires for individuals with CFS. Conclusion. Various sub-scales of SF36v2 demonstrated adequate reliability and validity for clinical and research applications. Adequacy of sensitivity to change of SF36v2 as a result of a fatiguing stressor should be the subject of additional study.
Match Demands of Senior and Junior Players During International Rugby League

Abstract Dempsey, GM, Gibson, NV, Sykes, D, Pryjmachuk, BC, and Turner, AP. Match demands of senior and junior players during International Rugby League. J Strength Cond Res 32(6): 1678–1684, 2018—This study aims to quantify and compare the positional game demands of international junior and senior rugby league competition for the first time. Global positioning system (GPS) and video analysis were used to track 118 elite male rugby league players (57 seniors aged 28.7 ± 4.4 years; 61 juniors aged 17.2 ± 0.5 years) over 10 international matches (6 senior; 4 junior) characterized as either forwards (n = 67) or backs (n = 51). There were significant increases in the offensive carries (0.18 cf. 0.09 n·min−1; r = 0.56) and defensive tackles (0.36 cf. 0.23 n·min−1; r = 0.3) between senior and junior players, and forwards and backs (0.16 cf. 0.09; r = 0.34 and 0.41 cf. 0.14; r = 0.52), respectively. Running demands were significantly greater in backs than forwards (independent of playing level) for total distance (6,962 ± 1,263 m cf. 4,879 ± 1,824 m; r = 0.55), individualized high-speed distances (310 ± 158 m cf. 250 ± 171 m; r = 0.2), high-intensity accelerations (28.7 ± 12.1 m·s−1 cf. 21.9 ± 11.7 m·s−1; r = 0.27), and decelerations (57.2 ± 18.3 m·s−1 cf. 43.0 ± 17.8 m·s−1; r = 0.38). Positional differences were eliminated when reported relative to minutes played. From a practical perspective, although running demands relative to time on the pitch may prepare junior players for senior competition, it is not representative of the increased body mass and contact frequency within the senior game. Coaches should therefore reflect these differences within their physical preparation programs to prepare junior athletes accordingly for progression to the senior level.
Effect of leg extension training on concentric and eccentric strength of quadriceps femoris muscles

Ten healthy male subjects carried out bilateral concentric leg extension training twice a week for 8 weeks. Before and after the training, maximal voluntary isometric and isokinetic strength and cross‐sectional areas of the quadriceps femoris were measured. Maximal bilateral leg extension power increased significantly after the training. Isometric and concentric unilateral strength did not change significantly before and after the training, while eccentric strength at 0.52 and 1.05 rad·s−1 increased after the training with no changes in cross‐sectional area. The correlations between strength and cross‐sectional area increased significantly after the training. It was speculated that the increase in eccentric strength of knee extensors was due to modification of the neural inhibition during eccentric muscle actions.
Playing safe: Media coverage of child sexual abuse prevention strategies

This paper examines the media coverage of preventing child sexual abuse. It draws on a content analysis of all press and TV news coverage about child sexual abuse that appeared in the UK during a complete 12-month period. The findings demonstrate that the bulk of the coverage was case-based, for example focusing on the Orkney case. There was very little opportunity for broader discussion of general issues of concern, including how sexual assaults against children might be prevented. The coverage of ‘prevention’ which did exist drew on a very narrow range of debates and was disproportionately concerned with abuse outside the home (abductions by strangers, or abuse within institutions such as schools or children's homes). Discussions about prevention were dominated by reactive news stories generated by particular ‘scandals’. The coverage was also largely drawn from a small constituency of official source agencies (such as government officials, court proceedings and police statements). There were few attempts to address the broader social conditions which might facilitate or inhibit sexual violence or to examine explicitly political analyses of the problem. The paper argues for a more diverse discussion about ways of preventing sexual violence against children, especially assaults by fathers, uncles, brothers and friends of the family. This demands close attention to the ways in which the mass media operate, as well as the priorities of source agencies. The paper points to factors within news production practices which both obstruct and facilitate debate about prevention and concludes by suggesting strategies to promote this issue as a vital part of the public agenda.
Modeling of nevirapine-based antiretroviral regimen response by taxonomy from different CD4 cell counts strata

The search for determinants responsible for changes in CD4 cells count can help to optimize the efficiency of the nevirapine-based antiretroviral therapy in Cote d'Ivoire. Our study on the response to this treatment was carried out through taxonomy of CD4 cells count trajectories using non-hierarchical-descendant model. One hundred and sixty four patients were grouped according to their baseline CD4 count in three strata (<100/mm
Emotional well-being and adjustment to vision loss in later life: a meta-synthesis of qualitative studies

Purpose: To review perceived emotional well-being in older people with visual impairment and perceived factors that inhibit/facilitate psychosocial adjustment to vision loss. Method: The databases of MEDLINE, EMBASE, PsycINFO and CINAHL were searched for studies published from January 1980 to December 2010, which recruited older people with irreversible vision loss, and used qualitative methods for both data collection and analysis. Results sections of the papers were synthesised using a thematic-style analysis to identify the emergent and dominant themes. Results: Seventeen qualitative papers were included in the review, and five main themes emerged from the synthesis: 1) the trauma of an ophthalmic diagnosis, 2) impact of vision loss on daily life, 3) negative impact of visual impairment on psychosocial well-being, 4) factors that inhibit social well-being, and 5) factors that facilitate psychological well-being. We found the response shift model useful for explaining our synthesis. Conclusions: Acquired visual impairment can have a significant impact on older people’s well-being and make psychosocial adjustment to the condition a major challenge. Acceptance of the condition and a positive attitude facilitate successful psychosocial adjustment to vision loss as well as social support from family, friends and peers who have successfully adjusted to the condition. Implications for Rehabilitation Visual impairment can have a profound negative impact on individuals’ psychosocial well-being. The emotional needs of those with visual impairment should not to be neglected, particularly those recently diagnosed. Referrals to services may be appropriate for individuals with vision loss (e.g. counselling and peer support groups). It may also be appropriate to discuss with individuals the factors that inhibit/facilitate psychosocial adjustment to vision loss.
Comparison of Acute Physiological and Psychological Responses Between Moderate-Intensity Continuous Exercise and Three Regimes of High-Intensity Interval Training

Abstract Olney, N, Wertz, T, LaPorta, Z, Mora, A, Serbas, J, and Astorino, TA. Comparison of acute physiological and psychological responses between moderate-intensity continuous exercise and three regimes of high intensity interval training. J Strength Cond Res 32(8): 2130–2138, 2018—High-intensity interval training (HIIT) elicits similar physiological adaptations as moderate-intensity continuous training (MICT) despite less time commitment. However, there is debate whether HIIT is more aversive than MICT. This study compared physiological and perceptual responses between MICT and 3 regimes of HIIT. Nineteen active adults (age = 24.0 ± 3.3 years) unfamiliar with HIIT initially performed ramp exercise to exhaustion to measure maximal oxygen uptake (V[Combining Dot Above]O2max) and determine workload for subsequent sessions, whose order was randomized. Sprint interval training (SIT) consisted of six 20-second bouts of “all-out” cycling at 140% of maximum watts (Wmax). Low-volume HIIT (HIITLV) and high-volume HIIT (HIITHV) consisted of eight 60-second bouts at 85% Wmax and six 2-minute bouts at 70% Wmax, respectively. Moderate-intensity continuous training consisted of 25 minutes at 40% Wmax. Across regimes, work was not matched. Heart rate (HR), V[Combining Dot Above]O2, blood lactate concentration (BLa), affect, and rating of perceived exertion (RPE) were assessed during exercise. Ten minutes postexercise, Physical Activity Enjoyment (PACES) was measured via a survey. Results revealed significantly higher (p ⩽ 0.05) V[Combining Dot Above]O2, HR, BLa, and RPE in SIT, HIITLV, and HIITHV vs. MICT. Despite a decline in affect during exercise (p < 0.01) and significantly lower affect (p ⩽ 0.05) during all HIIT regimes vs. MICT at 50, 75, and 100% of session duration, PACES was similar across regimes (p = 0.65), although it was higher in women (p = 0.03). Findings from healthy adults unaccustomed to interval training demonstrate that HIIT and SIT are perceived as enjoyable as MICT despite being more aversive.
Identifying factors associated with self-rated health according to age at onset of disability

Purpose: Although later-onset disability has been associated with poor self-rated health (SRH), factors mediating differences in SRH related to age at onset of disability remain unclear. The present study was designed to identify the variables explaining poor SRH in later-onset disability. We examined chronic disease and functional status as alternatives to psychosocial adaptation as explanatory variables. Method: Our data were taken from the seventh National Survey for People with Disabilities among Korean individuals ≥18 years of age (n =5311). Results: Those with later-onset disability (onset ages 20–40, 41–64 and ≥65 years) showed higher age-adjusted odds ratios (ORs) for poor SRH compared with those with earlier-onset disability (onset ages 0–19 years). The ORs for poor SRH in individuals with later-onset disability were not substantially changed after adjusting for confounding variables including alternatives to psychosocial adaptation (chronic diseases and functional status) as explanatory variables. Conclusions: Failure to explain poor SRH in later-onset disability with explanatory variables other than psychosocial adaptation indirectly supports the role of psychosocial adaptation in differences in SRH related to age at onset. Because we could not include appropriate measures of psychosocial adaptation, the use of additional instruments should be considered in future studies. Implications for Rehabilitation Poor health-related quality of life (HRQOL) in later-onset disability is not merely due to more prevalent chronic disease and worse functional status. Strategies in helping with psychosocial adaptation after disability may be important to promote HRQOL in people with later-onset disability.
Adaptive ability, behavior and quality of life pre and posttraumatic brain injury in childhood

Context: Traumatic brain injury (TBI) is a common, acquired childhood disability, which has been shown to have a significant impact on children’s cognitive and educational function. While behavioral problems are also noted, there is ongoing debate about the contribution of preinjury factors in this domain. Few studies have attempted to measure the impact of these preinjury functions on postinjury behavior. Objective: To compare pre and postinjury adaptive ability, behavior, executive function and quality of life (QOL) and to identify factors that contribute to outcomes in these domains including injury severity, socio-demographic and preinjury characteristics. Design: Consecutive recruitments to a prospective, longitudinal study, utilizing a between factor design, with injury severity as the independent variable. Participants and methods: Children admitted to hospital with a diagnosis of TBI aged between 6 and 14 years (n = 205) were divided according to injury severity (mild, moderate and severe). Adaptive behavior (Vineland Adaptive Behavior Scales), child behavior (Child Behavior Checklist), everyday executive functions (Behavior Rating Inventory of Executive Function) and QOL (Child Health Questionnaire) assessed at 6 months post-TBI. Results and conclusions: Severity by time interactions were identified across a range of outcome domains demonstrating that more severe injury is associated with a decrease in functional ability at 6 months post-TBI. This effect was most pronounced for everyday executive skills, social function and internalizing aspects of child behavior. Preinjury function was a consistent predictor of postinjury status. Injury severity contributed little to the prediction of functional outcomes once preinjury functioning was accounted for in the model. Age at injury and family cohesion were relevant to specific outcome domains only. Socio-economic status did not contribute significantly to outcome at 6 months. Preinjury functioning as reported by parents in the acute phase may be a useful predictive tool for identifying children who may be at risk of functioning difficulties 6 months post-TBI. Implications for Rehabilitation Childhood traumatic brain injury Priorities for intervention: (i) more severe injury; (ii) presence of pre-injury impairment; (iii) younger age at injury and (iv) evidence of family dysfunction. Level of functional impairment postinjury rarely meets criteria for a frank diagnosis (e.g. intellectual impairment and psychiatric disorder) and thus children are frequently ineligible for routine community supports. Reduced executive skills and social competence and elevated behavioral disturbances indicate that evidence-based interventions addressing these domains are a priority.
Living and Training at 825 m for 8 Weeks Supplemented With Intermittent Hypoxic Training at 3,000 m Improves Blood Parameters and Running Performance

Abstract Wonnabussapawich, P, Hamlin, MJ, Lizamore, CA, Manimmanakorn, N, Leelayuwat, N, Tunkamnerdthai, O, Thuwakum, W, and Manimmanakorn, A. Living and training at 825 m for 8 weeks supplemented with intermittent hypoxic training at 3,000 m improves blood parameters and running performance. J Strength Cond Res 31(12): 3287–3294, 2017—We aimed to investigate the effect of an 8-week low-altitude training block supplemented with intermittent hypoxic training, on blood and performance parameters in soccer players. Forty university-level male soccer players were separated into altitude (n = 20, 825 m) or sea-level (n = 20, 125 m) groups. Before (1–2 days ago) and after (1 and 14 days later) training, players were asked to give a resting venous blood sample and complete a series of performance tests. Compared with sea level, the altitude group increased erythropoietin, red blood cell (RBC) count, and hematocrit 1 day after training (42.6 ± 24.0%, 1.8 ± 1.3%, 1.4 ± 1.1%, mean ± 95% confidence limits (CL), respectively). By 14 days after training, only RBC count and hemoglobin were substantially higher in the altitude compared with the sea-level group (3.2 ± 1.8%, 2.9 ± 2.1% respectively). Compared with sea level, the altitude group 1–2 days after training improved their 50-m (−2.9 ± 1.4%) and 2,800-m (−2.9 ± 4.4%) run times and demonstrated a higher maximal aerobic speed (4.7 ± 7.4%). These performance changes remained at 14 days after training with the addition of a likely higher estimated V[Combining Dot Above]O2max in the altitude compared with the sea-level group (3.2 ± 3.0%). Eight weeks of low-altitude training, supplemented with regular bouts of intermittent hypoxic training at higher altitude, produced beneficial performance improvements in team-sport athletes, which may increase the viability of such training to coaches and players that cannot access more traditional high altitude venues.
