“…In addition, focusing on maximal contraction of a muscle group (e.g., internal focus) during strength exercise has been reported to be superior to increase muscle thickness than external focus (or simply moving the load during strength exercise) 47 . In contrast, external focus or distraction manoeuvres using dual tasks have been reported to improve muscular endurance 48–50 . Future studies are needed to investigate the effects of these cognitive variables on muscle strength and PWH functionality.…”

Introduction: Although strength exercise is often prescribed for people with haemophilia (PWH), it remains unknown how exercise variables and pain thresholds are used to prescribe strength training in PWH. Aim: To analyse how strength exercise variables and pain thresholds have been used to prescribe strength training in PWH. Methods: A systematic search was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases from inception to 7 September 2022. Studies whose intervention included strengthening training in adults with haemophilia were included. Two independent reviewers were involved in study selection, data extraction and risk of bias assessment.Results: Eighteen studies were included. The least reported variables among the studies were: prophylactic factor coverage (11.1%), pain threshold/tolerability (5.6%), intensity (50%), total or partial range of motion (27.8%), time under tension (27.8%), attentional focus modality (0%), therapist experience in haemophilia (33.3%) and adherence assessment (50%). In contrast, weekly frequency (94.4%), duration (weeks) (100%), number of sets/repetitions (88.9%), repetitions to failure/not to failure (77.8%), types of contraction (77.8%), rest duration (55.6%), progression (55.6%), supervision (77.8%), exercise equipment (72.2%) and adverse event record (77.8%) had a higher percentage of reported (>50% of studies). Conclusion: Future research on strength training for PWH should improve information on pain threshold and other important variables such as prophylactic factor

“…We used a reference MCID of 15 for pain and 10 for functional status based on previous findings 30–32. Furthermore, the MCID for the Biering-Sorensen test was 5.3 s as reported by Cruz-Montecinos et al 33. The number needed to treat was also calculated using the Psychometrica online calculator (http://www.psychometrica.de/effect_size.html) as an estimate of the clinical benefit for the primary outcomes.…”

ObjectiveTo evaluate the effectiveness of motor control training (MCT) compared with other physical therapist-led interventions, minimal/no intervention or surgery in patients with symptomatic lumbar disc herniation (LDH).DesignSystematic review and meta-analysis.Data sourcesEight databases and the ClinicalTrials.gov were searched from inception to April 2021.Eligibility criteriaWe included clinical trial studies with concurrent comparison groups which examined the effectiveness of MCT in patients with symptomatic LDH. Primary outcomes were pain intensity and functional status which were expressed as mean difference (MD) and standardised mean difference (SMD), respectively.ResultsWe screened 6695 articles, of which 16 clinical trials (861 participants) were eligible. Fourteen studies were judged to have high risk of bias and two studies had some risk of bias. In patients who did not undergo surgery, MCT resulted in clinically meaningful pain reduction compared with other physical therapist-led interventions (ie, transcutaneous electrical nerve stimulation (TENS)) at short-term (MD –28.85, –40.04 to −17.66, n=69, studies=2). However, the robustness of the finding was poor. For functional status, a large and statistically significant treatment effect was found in favour of MCT compared with traditional/classic general exercises at long-term (SMD −0.83 to –1.35 to −0.31, n=63, studies=1) and other physical therapist-led interventions (ie, TENS) at short-term (SMD −1.43 to –2.41 to −0.46, n=69, studies=2). No studies compared MCT with surgery. In patients who had undergone surgery, large SMDs were seen. In favour of MCT compared with traditional/classic general exercises (SMD −0.95 to –1.32 to −0.58, n=124, studies=3), other physical therapist-led interventions (ie, conventional treatments; SMD −2.30 to –2.96 to −1.64, n=60, studies=1), and minimal intervention (SMD −1.34 to –1.87 to −0.81, n=68, studies=2) for functional improvement at short-term. The overall certainty of evidence was very low to low.ConclusionAt short-term, MCT improved pain and function compared with TENS in patients with symptomatic LDH who did not have surgery. MCT improved function compared with traditional/classic general exercises at long-term in patients who had undergone surgery. However, the results should be interpreted with caution because of the high risk of bias in the majority of studies.PROSPERO registration numberCRD42016038166.

“…Alternations between tasks of a predominantly physical or predominantly cognitive character may occur in other occupations, such as retail and some industrial jobs (Jahncke et al, 2017). Concurrent combinations of physical and cognitive tasks appear to influence motor performance and endurance time compared to only doing the physical task, either in a negative way because the effort increases (Au and Keir, 2007;Mehta andAgnew, 2011, 2012a;Srinivasan et al, 2016;Longo et al, 2018), or positively, by increasing endurance through distraction (Blanchfield et al, 2014;Aleksandrov and Knyazeva, 2017;Grande-Alonso et al, 2020;Cruz-Montezinos et al, 2021). Even the effects on stress and cardiovascular responses appear to be mixed (Finsen et al, 2001a;Alkjaer et al, 2005).…”

Objectives Physical and cognitive tasks occur together in many occupations. Previous reviews of combined tasks have mainly focused on their effects in a sports context. This review investigated to which extent combinations (concurrent or alternating) of occupationally relevant physical and cognitive tasks influence responses reflecting biomechanical exposure, stress, fatigue, performance, and well-being. Methods We searched Scopus, Pubmed, Cinahl, and Psychinfo for controlled experiments investigating the effects of combinations of occupationally relevant physical and cognitive tasks in participants aged 18 to 70. In total, we identified 12 447 records. We added recent papers that had cited these studies (n = 573) to arrive at a total of 13 020 publications. After screening for relevance, 61 studies remained, of which 57 were classified to be of medium or high quality. Of the 57 studies, 51 addressed concurrent tasks, 5 alternating tasks, and 1 both concurrent and alternating tasks. Results Most studies of concurrent physical and cognitive tasks reported negative effects, if numerically small, on indicators of biomechanical exposure, fatigue, and performance, compared to a physical task alone. Results were mixed for stress indicators, and well-being was too little studied to justify any conclusions. Effects depended on the tasks, including their intensity and complexity. Alternating physical and cognitive tasks did not appear to influence outcomes much, compared to having passive breaks in-between physical tasks. Conclusions The reviewed evidence indicated that concurrent physical and cognitive work tasks have negative, yet small effects on biomechanical indicators, fatigue and performance, compared to performing the physical task alone, but only if the physical task is intense, and the cognitive task is complex. Alternating between physical and cognitive tasks may have similar effects as breaking up physical tasks by passive breaks, but studies were few. Future studies should address ecologically valid combinations of physical and cognitive tasks, in particular in controlled field studies devoted to the long-term effects of combined work.
