A Systematic Review of the Role of Vitamin D on Neuromuscular Remodelling Following Exercise and Injury
(Springer, 2015-12-19) Minshull, Claire; Biant, Leela C.; Ralston, Stuart H.; Gleeson, Nigel
Vitamin D is important for skeletal muscle health and deficiency is associated with clinical neuromuscular symptoms of poor strength and gait. Supplementation can independently increase muscle strength in chronically deficient populations. However, the regulatory role of vitamin D on neuromuscular remodelling and adaptation subsequent to exercise conditioning or injury has not been systematically reviewed. Objective: to systematically review the available evidence of the role of vitamin D on neuromuscular remodelling following exercise conditioning, exercise- or experimentally induced injury. We searched Medline (OVID platform), PubMed, Embase and Web of Science for randomised controlled trials (RCTs) including measures of neuromuscular function, injury and/or inflammation; a physiologically stressful intervention involving exercise conditioning, exercise- or experimentally induced injury and; vitamin D supplementation. Nine RCTs met the inclusion criteria. Significant heterogeneity of methodological approaches and outcomes meant that meta-analysis of data was limited. Qualitative findings indicated that vitamin D may be an effective accelerant of neuromuscular remodelling in animal models (24-140 % improved recovery vs. control); the effects in humans are inconclusive and likely influenced by baseline vitamin D and supplementation strategy. Results of the meta-analyses indicated no effect of vitamin D supplementation on muscle strength adaptation following resistance training [standardised mean difference (SMD): 0.74, P = 0.42] or muscle damage (SMD: -0.03, P = 0.92), although inflammatory markers were elevated in the latter (SMD: 0.56, P = 0.04). Data from animal models offer promising and plausible mechanisms for vitamin D as an agent for neuromuscular adaptation. Further high-quality research is needed to offer clearer insight into the influential role of vitamin D in human populations.

Antecedent anterior cruciate ligament reconstruction surgery and optimal duration of supervised physiotherapy
(IOS Press, 2015-12) Darain, Haider; Alkitani, Abdulhameed; Yates, Christopher; Bailey, Andrea; Roberts, Simon; Coutts, Fiona; Gleeson, Nigel
A 22-year-old patient undergoing unilateral surgical reconstruction of the anterior cruciate ligament (ACL) of the right knee volunteered for the research project and followed an established contemporary hospital-based rehabilitation programme. The patient was supervised post-surgically by an experienced and clinically specialized physiotherapist. The clinical outcomes of rehabilitation were assessed by selected validated patient-reported and objectively-measured outcomes of functional performance capability on four different occasions (pre-surgery, 6th, 12th and 24th week post-surgery). The patient scored 30, 56, 60 and 85 on IKDC (maximum score, 100); 46, 53, 90 and 91 on Lysholm (maximum score, 100); 141, 73, 128 and 175 on K-SES (maximum score, 220); 17, 12, 6 and 6 on the symptom subsection of KOOS (maximum score, 28); 7, 7, 5 and 5 on the pain subsection (maximum score, 36); 1, 0, 3 and 1 on the daily function subsection (maximum score, 68); 0, 0, 5 and 5 on the sport and recreation function subsection (maximum score, 20); 13, 11, 15 and 13 on the quality of life subsection (maximum score, 16) of KOOS at pre-surgery and at the 6th, 12th and 24th week following ACL reconstruction, respectively. Moreover, the patient scored 1.96 m, 1.92 m and 1.99 m on single-leg hop (injured leg) when assessed at pre-surgery and at the 12th and 24th week post-surgery, respectively, following ACL reconstruction. The total time spent in supervised rehabilitation by the patient (675 minutes) was computed as the aggregate patient-reported time spent in exercise during each hospital-based rehabilitation session (verified by physiotherapist evaluation) across the total number of sessions. The patient managed to return to the sport in which he had participated prior to the injury, immediately after the completion of the contemporary rehabilitation programme, at 24 weeks post-surgery. A total of fifteen physiotherapy sessions supervised by the physiotherapist, were attended by the patient during the 24 week rehabilitation period. The latter number of physiotherapy sessions was substantially less than the average supervised physiotherapy sessions reported in the literature. 2015 - IOS Press and the authors.

Congruency and responsiveness of perceived exertion and task duration associated with an intermittent isometric fatigue task
(Elsevier, 2021-11-21) Peer, M. A.; Gallacher, P. D.; Coutts, Fiona; Gleeson, Nigel
Purpose: The shift away from supervised rehabilitation towards greater self-management requires that people are able to accurately self-monitor their exercise performance and exertion and apply appropriately dosed exercise to achieve optimal outcomes. An extended period of sub-optimal exercise may result in insufficient physiological stress to restore knee function and recovery to a level of PA similar to asymptomatic peers. Subsequently greater post-operative healthcare burdens may be imposed on limited NHS resources. It is currently unclear whether measures of exercise self-perception of exertional stress (CR-10 and perceived task duration [PTD]) demonstrate a similar pattern of change in a clinical population such as total knee arthroplasty (TKA) and thus, may be recommended as a scale for regulating exercise performance during resistance training. The aim was to enhance the understanding regarding whether people are able to accurately calibrate self-perceived exercise performance capability and perceptions of exertional stress. Further, this study intended to identify whether perceived exertion offers a precise reflection of task duration.
Congruency and responsiveness of perceived exertion and time-to-end-point during an intermittent isometric fatigue task
(Springer Verlag, 2013-04) Shepherd, J.; Gleeson, Nigel; Minshull, Claire
The aims of this study were (1) to investigate the relationship between self-perception of effort and task duration in an intermittent isometric fatigue trial (IIF) and (2) to evaluate the capability of two assessment paradigms (perceived exertion; perceived task duration) to reflect changes in IIF intensity. Fifteen participants performed two IIF tasks of the knee extensors at intensities of 60 and 70 % of daily peak force, each separated by 48-72 h. Ordering of the tasks was counter-balanced and participants were blinded to the precise intensity of each IIF. A category-ratio scale (CR-10) and visual analogue scale were used during each IIF task to record measures of perceived exertion and perceived task duration, respectively. Measures were recorded at 10 % intervals across the relative duration of each IIF task. Pearson product-moment correlation coefficients revealed strong positive correlations (r > 0.99; p < 0.01) between completed task duration and both perceptual scales at the two IIF intensities. Separate two-way repeated measures ANOVAs of CR-10 and perceived task duration responses revealed significant main effects for time only (F [2.2,30.1] = 126.8; p < 0.001; F [2.6,36.8] = 117.2; p < 0.001, CR-10 and perceived task duration, respectively). The results suggest that perceived exertion and perceived task duration are equally effective predictors of IIF end-point. However, neither measure was sufficiently responsive to discriminate between 10 % changes in exercise intensity. 2012 Springer-Verlag.
Considerations of the Principles of Resistance Training in Exercise Studies for the Management of Knee Osteoarthritis: A Systematic Review
(W.B. Saunders, 2017-03-31) Minshull, Claire; Gleeson, Nigel
Objective: To evaluate the methodologic quality of resistance training interventions for the management of knee osteoarthritis. Data Sources: A search of the literature for studies published up to August 10, 2015, was performed on MEDLINE (OVID platform), PubMed, Embase, and Physiotherapy Evidence Database databases. Search terms associated with osteoarthritis, knee, and muscle resistance exercise were used. Study Selection: Studies were included in the review if they were published in the English language and met the following criteria: (1) muscle resistance training was the primary intervention; (2) randomized controlled trial design; (3) treatment arms included at least a muscle conditioning intervention and a nonexercise group; and (4) participants had osteoarthritis of the knee. Studies using preoperative (joint replacement) interventions with only postoperative outcomes were excluded. The search yielded 1574 results. The inclusion criteria were met by 34 studies. Data Extraction: Two reviewers independently screened the articles for eligibility. Critical appraisal of the methodology was assessed according to the principles of resistance training and separately for the reporting of adherence using a specially designed scoring system. A rating for each article was assigned. Data Synthesis: There were 34 studies that described a strength training focus of the intervention; however, the principles of resistance training were inconsistently applied and inadequately reported across all. Methods for adherence monitoring were incorporated into the design of 28 of the studies, but only 13 reported sufficient detail to estimate average dose of exercise. Conclusions: These findings affect the interpretation of the efficacy of muscle resistance exercise in the management of knee osteoarthritis. Clinicians and health care professionals cannot be confident whether nonsignificant findings are because of the lack of efficacy of muscle resistance interventions, or occur through limitations in treatment prescription and patient adherence. Future research that seeks to evaluate the effects of muscle strength training interventions on symptoms of osteoarthritis should be properly designed and adherence diligently reported. 2016 American Congress of Rehabilitation Medicine.

Description of arts therapies practice with adults suffering from depression in the UK: Qualitative findings from the nationwide survey
(Elsevier, 2014-11) Zubala, Ania; MacIntyre, Donald J.; Gleeson, Nigel; Karkou, Vicky
There is growing evidence that arts therapies present a relevant treatment option for depression, but the experiences, methods, tools and methods of practice of arts therapists with this client group remain unclear. Thus, this research study aimed to describe the specifics of the practice of arts therapies with depression. In 2011, all arts therapists registered in the UK were invited to complete an online questionnaire concerning their practice in general and in relation to depression. The Arts Therapies Survey received 395 responses. Arts therapists who work primarily with depression were identified and compared to those who do not work with depression on a range of factors. These quantitative results were presented elsewhere (Zubala, MacIntyre, Gleeson, & Karkou, 2013). An analysis of the qualitative material was guided by the strategy of grounded theory, and findings were obtained through thematic analysis. The current paper introduces these findings, adding depth to the knowledge previously gained through the quantitative analysis. Arts therapists worked across various settings with highly complex clients; however, therapists struggled with the tension of providing care according to guidelines, which they found inflexible and at times misguided. The therapists tended to vary the theoretical model of their therapeutic approach depending on individual client factors and often collaborated with other professionals using a variety of standardized tools to measure outcomes. The findings further offer a detailed understanding of the therapeutic process and describe the meaning of clinical practice within arts therapies.
Description of arts therapies practice with adults suffering from depression in the UK: Quantitative results from the nationwide survey
(Elsevier, 2013-11) Zubala, Ania; MacIntyre, D. J.; Gleeson, Nigel; Karkou, Vicky
There is growing evidence that arts therapies may be under-used treatments for the 'global burden' of depression. However, the experiences of arts therapists, their methods, tools and ways of working with this client group remain unclear. Arts therapies in the UK are a form of psychotherapy. They use arts media alongside therapeutic relationship as means of therapeutic change and include four disciplines: Art Therapy (AT), Music Therapy (MT), Dance Movement Psychotherapy (DMP) and Drama Therapy (DT). In 2011, all arts therapists registered in the UK were invited to complete an online questionnaire concerning their practice in general and specifically in relation to clients with depression. The Arts Therapies Survey received 395 responses. Arts therapists who work primarily with depression were identified and compared to those who do not work with depression on a range of factors, including preferred theoretical approaches and style of working. Arts therapists who specialise in depression tend to follow Psychodynamic principles more often, are more likely to be older and experienced, work with groups, in health settings and with adults more often than children or adolescents. These quantitative findings enable the description of most common practice of arts therapies with depression in the UK and are intended to serve as a reference for arts therapists themselves and other professionals interested in the treatment of depression. Qualitative data gathered in the survey will be presented in a separate paper, with the aim of deepening the understanding already gained. 2013 Elsevier Ltd.
Development of a walking test for the assessment of functional capacity in non-anaemic maintenance dialysis patients
(Oxford University Press, 1998-08) Mercer, Tom; Naish, P. F.; Gleeson, Nigel; Wilcock, J. E.; Crawford, C.
Background. Walk tests may be useful adjuncts or even alternatives to the assessment of peak oxygen uptake (VO2 peak) in patients with low functional capacity. Walk tests are easy to administer, appear to be well tolerated by patients and may represent a more meaningful measure for a patient group as they assess capability as well as fitness. However, the use of walk tests for the assessment of functional capacity in maintenance dialysis patients has received scant attention. The aim of this study was to assess the validity of a walking-stair-climbing test to predict VO2 peak in non-anaemic maintenance dialysis patients. Methods. In the validation phase of the study, 14 subjects completed a cycle ergometer-graded exercise test (GXT) for the determination of VO2 peak and a walking-stair-climbing task (WALK), each separated by a period of 7 days. Three weeks later, 18 subjects completed two WALK tests, each separated by a period of at least 48 h, to facilitate reliability estimation. Estimates of differentiated and undifferentiated ratings of perceived exertion (RPE) were obtained during and immediately consequent to all exercise tests. Results. VO 2 peak (ml kg min) was significantly correlated with total WALK time (s) (r = -0.83; P <0.001). VO2 peak (ml kg min) could be predicted from total WALK time with a standard error of prediction of 11%. Reliability assessment revealed no significant differences for any aspect of the WALK test performance, with test-retest correlation coefficients ranging from r = 0.71 (RPElegs) to 0.96 (total WALK time). Conclusion. These results indicate that the WALK test is a valid, reliable and potentially useful method by which to assess the functional capacity of non-anaemic

Early initiation of home-based sensori-motor training improves muscle strength, activation and size in patients after knee replacement: A secondary analysis of a controlled clinical trial
(Springer Nature, 2019-05-17) Moutzouri, Maria; Coutts, Fiona; Gliatis, John; Billis, Evdokia; Tsepis, Elias; Gleeson, Nigel
Background There is accumulating evidence for the advantages of rehabilitation involving sensori-motor training (SMT) following total knee replacement (TKR). However, the best way in which to deliver SMT remains elusive because of potential interference effects amongst concurrent exercise stimuli for optimal neuromuscular and morphological adaptations. The aim of this study was to use additional outcomes (i.e. muscle strength, activation and size) from a published parent study to compare the effects of early-initiated home-based rehabilitative SMT with functional exercise training (usual care) in patients undergoing TKR.
Early self-managed focal sensorimotor rehabilitative training enhances functional mobility and sensorimotor function in patients following total knee replacement: a controlled clinical trial
(SAGE Publications, 2018-02-23) Moutzouri, Maria; Gleeson, Nigel; Coutts, Fiona; Tsepis, Elias; John, Gliatis
Objective: To assess the effects of early self-managed focal sensorimotor training compared to functional exercise training after total knee replacement on functional mobility and sensorimotor function. Design: A single-blind controlled clinical trial. Setting: University Hospital of Rion, Greece. Subjects: A total of 52 participants following total knee replacement. Outcome measures: The primary outcome was the Timed Up and Go Test and the secondary outcomes were balance, joint position error, the Knee Outcome Survey Activities of Daily Living Scale, and pain. Patients were assessed on three separate occasions (presurgery, 8-weeks post surgery, and 14-weeks post surgery). Intervention: Participants were randomized to either focal sensorimotor exercise training (experimental group) or functional exercise training (control group). Both groups received a 12-week home-based programme prescribed for 3-5 sessions/week (35-45-minutes). Results: Consistently greater improvements (F2,98-=-4.3 to 24.8; P-<-0.05) in group mean scores favour the experimental group compared to the control group: Timed Up and Go (7.8--2.9-seconds vs. 4.6--2.6-seconds); balance (2.1--0.9 vs. 0.7--1.2); joint position error (13.8--7.3 vs. 6.2--9.1); Knee Outcome Survey Activities of Daily Living Scale (44.2--11.3 vs. 26.1--11.4); and pain (5.9--1.3-cm vs. 4.6--1.1-cm). Patterns of improvement for the experimental group over time were represented by a relative effect size range of 1.3-6.5. Conclusions: Overall, the magnitude of improvements in functional mobility and sensorimotor function endorses using focal sensorimotor training as an effective mode of rehabilitation following knee replacement.

Effect of flexibility training on symptoms of exercise-induced muscle damage: A preliminary study
(Hong Kong Association of Sports Medicine & Sports Science, 2007) Eston, R.; Rowlands, A. V.; Coulton, D.; Mckinney, J.; Gleeson, Nigel
Exercise-induced muscle damage (EIMD) is characterized by loss of strength, increase In muscle stiffness, swelling, and soreness. The aim of this study was to assess the effects of flexibility training of the hamstring muscle group on symptoms of EIMD. Fourteen males (mean standard deviation: age = 20.6 0.8 years; mass = 77.3 10.4 kg; height = 1.77 0.05 m) were randomly assigned to a 5-week flexibility (proprioceptive neuromuscular facilitation [PNF]) training or control group. Pre- and post-measures of peak static muscle force at knee joint angles representing decreasing muscle lengths of the hamstrings (25 deg, 30 deg, 40 deg, 80 deg) and flexibility were taken. Flexibility increased significantly following PNF flexibility training (pre-test = 19.4 6.2 cm, post-test = 26.6 6.9 cm), whereas it stayed constant in the control group (pre-test = 16.0 9.3 cm, post-test = 16.7 7.6 cm). Both groups underwent a damaging exercise protocol incorporating six sets of 10 isokinetic eccentric contractions of the hamstrings. Measurements of isometric strength, flexibility, and perceived soreness were recorded prior to and 1, 24, 48 and 72 hours after damage. There was a tendency for the PNF group to recover from strength loss earlier at longer muscle lengths (25 deg, p = 0.06; 30 deg, p = 0.05), but not at shorter muscle lengths. There was no evidence of a protective effect of PNF training on flexibility and soreness. In conclusion, an increase in flexibility of the hamstring muscle group led to some protection from strength loss at long muscle lengths following EIMD.
Effects of acute fatigue on the volitional and magnetically-evoked electromechanical delay of the knee flexors in males and females
(Springer Verlag, 2007-07) Minshull, Claire; Gleeson, Nigel; Walters-Edwards, M.; Eston, R.; Rees, D.
Neuromuscular performance capabilities, including those measured by evoked responses, may be adversely affected by fatigue; however, the capability of the neuromuscular system to initiate muscle force rapidly under these circumstances is yet to be established. Sex-differences in the acute responses of neuromuscular performance to exercise stress may be linked to evidence that females are much more vulnerable to anterior cruciate ligament injury than males. Optimal functioning of the knee flexors is paramount to the dynamic stabilisation of the knee joint, therefore the aim of this investigation was to examine the effects of acute maximal intensity fatiguing exercise on the voluntary and magnetically-evoked electromechanical delay in the knee flexors of males and females. Knee flexor volitional and magnetically-evoked neuromuscular performance was assessed in seven male and nine females prior to and immediately after: (1) an intervention condition comprising a fatigue trial of 30-s maximal static exercise of the knee flexors, (2) a control condition consisting of no exercise. The results showed that the fatigue intervention was associated with a substantive reduction in volitional peak force that was greater in males compared to females (15.0, 10.2%, respectively, P < 0.01) and impairment to volitional electromechanical delay in females exclusively (19.3%, P < 0.05). Similar improvements in magnetically-evoked electromechanical delay in males and females following fatigue (21%, P < 0.001), however, may suggest a vital facilitatory mechanism to overcome the effects of impaired voluntary capabilities, and a faster neuromuscular response that can be deployed during critical times to protect the joint system.
Effects of antecedent flexibility conditioning on neuromuscular and sensorimotor performance during exercise-induced muscle damage
(Hong Kong Association of Sports Medicine & Sports Science, 2013-12) Gleeson, Nigel; Eston, R.; Minshull, Claire; Bailey, A.; Al Kitani, Abdul Hameed; Darain, Haider; Yates, C.; Rees, D.
The aim of this study was to assess the effects of two modes of antecedent flexibility conditioning on neuromuscular and sensorimotor performance during a subsequent episode of exercise-induced muscle damage (EIMD). Twenty-four males (age 20.9 2.3 years; height 1.78 0.06 m; body mass 72.3 7.4 kg, mean SD) were randomly assigned to interventions comprising 6 weeks of thrice-weekly flexibility conditioning of the hip region and knee flexor musculature in the dominant limb involving proprioceptive neuromuscular facilitation (n = 8), passive exercise (n = 8), or no exercise as a control (n = 8). Musculoskeletal, neuromuscular, and sensorimotor assessments were carried out at baseline, after conditioning, and before and up to 168 hours after damaging exercise of the ipsilateral knee flexors. Flexibility conditioning and EIMD elicited transient performance decreases in volitional electromechanical delay (up to 40.1% compared to baseline; 67.5 12.3 milliseconds vs. 47.9 9.7 milliseconds, mean SD, 48-hour post- vs. pre-EIMD; p < 0.01), passive hip flexibility (up to 19.9%; 96.7 8.2 vs. 120.7 11.0, p < 0.001) and sensorimotor capability (manifold error increase to 10.8%; 10.8% 6.9% vs. 0.3% 3.7%, p < 0.05) and exceeded the effects of eccentric exercise alone. EIMD-related performance decreases were especially prominent when preceded by passive flexibility conditioning, and were sufficiently potent following both modes of antecedent conditioning to raise concerns about compromised capability for rapid and dynamic stabilization of synovial joints. 2013.
Effects of stretching on performances involving stretch-shortening cycles
(Adis Online, 2013-08) Kallerud, H.; Gleeson, Nigel
Background: Alongside its role in athletic conditioning, stretching has commonly been integrated in warm-up routines prior to athletic performance. Numerous studies have reported detrimental acute effects on strength following stretching. Consequently, athletes have been recommended to discontinue stretching as part of warm-ups. In contrast, studies indicate that chronic stretching performed as a separate bout from training or competition may enhance performance. However, the influence of stretching on complex performances has received relatively little attention. Objective: The purpose of this study was to review both the acute and chronic effects of stretching on performances involving the stretch-shortening cycle (SSC). Methods: A systematic search for literature was undertaken (January 2006-December 2012) in which only randomized controlled trials (RCTs) or studies with repeated measures designs were included. The Physiotherapy Evidence Database (PEDro) rating scale was used for quality assessment of the evidence. Results: The review included 43 studies, from which conflicting evidence emerged. Approximately half of the studies assessing the acute effect of static stretching reported a detrimental effect on performance, while the remainder found no effect. In contrast, dynamic stretching showed no negative effects and improved performance in half of the trials. The effect size associated with static and dynamic stretching interventions was commonly low to moderate, indicating that the effect on performance might be limited in practice. Factors were identified that might have contributed to the conflicting results reported across studies, such as type of SSC performance and carrying out dynamic activity between the stretching bout and performance. Few studies since 2006 have addressed the chronic effect of stretching on functional and sports performance. Although negative effects were not reported, robust evidence of the overall beneficial effects within current bibliographic databases remains elusive. Plausible mechanisms for the observed effects from stretching are discussed, as well as possible factors that may have contributed to contradictory findings between studies. Limitations: Considerable heterogeneity in study design and methods makes comparison between studies challenging. No regression analysis of the contribution of different predictors to variation between trials had previously been performed. Hence, predictors had to be selected on the basis of a qualitative analysis of the predictors that seemed most influential, as well as being identified in previous narrative reviews. Conclusion: Different types of stretching have differential acute effects on SSC performances. The recommended volume of static stretching required to increase flexibility might induce a negative acute effect on performances involving rapid SSCs, but the effect sizes of these decrements are commonly low, indicating that the acute effect on performance might be limited in practice. No negative acute effects of dynamic stretching were reported. For athletes that require great range of motion (ROM) and speed in their sport, long-term stretching successfully enhances flexibility without negatively affecting performance. Acute dynamic stretching may also be effective in inducing smaller gains in ROM prior to performance without any negative effects being observed. 2013 Springer International Publishing Switzerland.
Enhancing clinically-relevant shoulder function assessment using only essential movements
(2015-03) Pichonnaz, Claude; Lcureux, E.; Bassin, J-P; Duc, C.; Farron, A.; Aminian, K.; Jolles, B. M.; Gleeson, Nigel
Kinematic functional evaluation with body-worn sensors provides discriminative and responsive scores after shoulder surgery, but the optimal movements' combination has not yet been scientifically investigated. The aim of this study was the development of a simplified shoulder function kinematic score including only essential movements. The P Score, a seven-movement kinematic score developed on 31 healthy participants and 35 patients before surgery and at 3, 6 and 12-months after shoulder surgery, served as a reference. Principal component analysis and multiple regression were used to create simplified scoring models. The candidate models were compared to the reference score. ROC curve for shoulder pathology detection and correlations with clinical questionnaires were calculated. The B-B Score (hand to the Back and hand upwards as to change a Bulb) showed no difference to the P Score in time*score interaction (P > .05) and its relation with the reference score was highly linear (R2 > .97). Absolute value of correlations with clinical questionnaires ranged from 0.51 to 0.77. Sensitivity was 97% and specificity 94%. The B-B and reference scores are equivalent for the measurement of group responses. The validated simplified scoring model presents practical advantages that facilitate the objective evaluation of shoulder function in clinical practice.
