efficacy of Functional strength Training on restoration of lower limb motor function early after stroke phase i randomized controlled trial
Neurorehabilitation and Neural Repair, 2010Co-Authors: Emma V Cooke, Raymond Tallis, Allan Clark, Valerie M PomeroyAbstract:After stroke, physiotherapy can promote brain reorganization and motor recovery. Combining muscle strength and Functional Training (Functional strength Training, FST) may be beneficial. The aim of the authors was to compare FST with conventional physiotherapy (CPT) while controlling for the potential confounder of therapy intensity in a multicenter, randomized controlled observer-blind trial. The mean age of the participants was 68.3 (standard deviation [SD] = 12.03) years at a mean of 34 (SD = 20) days after stroke, with mean peak paretic knee extension torque (torque) of 22 (SD = 25) Nm. The estimated sample size was 102 to detect a between-group difference of 0.2 m/s in walking speed. After baseline measures, participants were allocated randomly to CPT or CPT + CPT or CPT + FST for 6 weeks. Additional experimental therapy was provided for up to 1 hour a day, 4 times each week. Outcomes were measured 6 weeks after baseline and at follow-up 12 weeks thereafter. Measures included walking speed, knee exten...

effects of conventional physical therapy and Functional strength Training on upper limb motor recovery after stroke a randomized phase ii study
Neurorehabilitation and Neural Repair, 2009Co-Authors: Catherine Donaldson, Raymond Tallis, Simon Miller, Alan Sunderland, Roger N Lemon, Valerie M PomeroyAbstract:Background. Functional Training and muscle strength Training may improve upper limb motor recovery after stroke. Combining these as Functional strength Training (FST) might enhance the benefit, but it is unclear whether this is better than conventional physical therapy (CPT). Comparing FST with CPT is not straightforward. Objective. This study aimed at assessing the feasibility of conducting a phase III trial comparing CPT with FST for upper limb recovery. Methods. Randomized, observer-blind, phase II trial. Subjects had upper limb weakness within 3 months of anterior circulation infarction. Subjects were randomized to CPT (no extra therapy), CPT + CPT, and CPT + FST. Intervention lasted 6 weeks. Primary outcome measure was the Action Research Arm Test (ARAT). Measurements were taken before treatment began, after 6 weeks of intervention, and 12 weeks thereafter. Attrition rate was calculated and differences between groups were interpreted using descriptive statistics. ARAT data were used to inform a power...

examining a novel firefighter exercise Training program on simulated fire ground test performance cardiorespiratory endurance and strength a pilot investigation
Journal of Occupational Medicine and Toxicology, 2019Co-Authors: Walker S C Poston, Sara A Jahnke, Brittany S Hollerbach, Craig A Harms, Katie M HeinrichAbstract:Firefighting is a dangerous occupation with high rates of injuries and fatalities, with the majority of line of duty fatalities due to cardiovascular events. Additionally, firefighters struggle with poor health/low levels of fitness, including high (> 80%) rates of overweight and obesity. Limited resources exist for fire departments that are tailored to the culture and work requirements of these “tactical athletes”. Though there has been increasing interest in high intensity Functional Training (HIFT) programs, research data are lacking among firefighters and few studies have focused on Training recruits. The purpose of this pilot investigation was to examine a novel HIFT program (TF20) on fire academy recruits’ health, fitness, and performance as determined by a simulated fire ground test (SFGT), as well as determining the program’s acceptability and feasibility. Thirteen participants were recruited from an entry level fire academy and were randomly assigned to the control (CG, n = 6) or HIFT group (TF20, n = 7). The CG was asked to continue current exercise habits. TF20 was provided a 10-week online based Training program that included periodized workouts, nutritional information, and mental readiness education. Due to attrition within the first two weeks of the study, 10 male fire recruits (23 ± 3 years) completed the study (CG, n = 3, TF20, n = 7). All 10 participants completed baseline and follow-up assessments. The TF20 group showed improvement on numerous outcome measures including SFGT (40% passing at baseline, 86% passing post-intervention). TF20 participants significantly increased estimated VO2max (p = 0.028), improved body composition (p = 0.028), and improved grip strength (p = 0.018). The CG did not experience any significant changes. The TF20 group completed approximately 75% of the assigned workouts. While TF20 participants showed significant fitness gains, the small sample size limited direct comparisons to the CG. TF20 was well-received although there may be a better way to implement the intervention to increase participation. This investigation provides promising outcomes, useful information about implementation, feasibility, and acceptability for the TF20 HIFT program among firefighter recruits.

high intensity Functional Training hift definition and research implications for improved fitness
Sports (Basel Switzerland), 2018Co-Authors: Yuri Feito, Katie M Heinrich, Scotty J Butcher, Walker S C PostonAbstract:High-intensity Functional Training (HIFT) is an exercise modality that emphasizes Functional, multi-joint movements that can be modified to any fitness level and elicit greater muscle recruitment than more traditional exercise. As a relatively new Training modality, HIFT is often compared to high-intensity interval Training (HIIT), yet the two are distinct. HIIT exercise is characterized by relatively short bursts of repeated vigorous activity, interspersed by periods of rest or low-intensity exercise for recovery, while HIFT utilizes constantly varied Functional exercises and various activity durations that may or may not incorporate rest. Over the last decade, studies evaluating the effectiveness of HIIT programs have documented improvements in metabolic and cardiorespiratory adaptations; however, less is known about the effects of HIFT. The purpose of this manuscript is to provide a working definition of HIFT and review the available literature regarding its use to improve metabolic and cardiorespiratory adaptations in strength and conditioning programs among various populations. Additionally, we aim to create a definition that is used in future publications to evaluate more effectively the future impact of this type of Training on health and fitness outcomes.

are changes in physical work capacity induced by high intensity Functional Training related to changes in associated physiologic measures
2018Co-Authors: Derek A. Crawford, Nicholas B. Drake, Michael J. Carper, Justin Deblauw, Katie M HeinrichAbstract:High-Intensity Functional Training (HIFT) is a novel exercise intervention that may test body systems in a balanced and integrated fashion by challenging individuals’ abilities to complete mechanical work. However, research has not previously determined if physical work capacity is unique to traditional physiologic measures of fitness. Twenty-five healthy men and women completed a six-week HIFT intervention with physical work capacity and various physiologic measures of fitness assessed pre- and post-intervention. At baseline, these physiologic measures of fitness (e.g., aerobic capacity) were significantly associated with physical work capacity and this relationship was even stronger at post-intervention assessment. Further, there were significant improvements across these physiologic measures in response to the delivered intervention. However, the change in these physiologic measures failed to predict the change in physical work capacity induced via HIFT. These findings point to the potential utility of HIFT as a unique challenge to individuals’ physiology beyond traditional resistance or aerobic Training. Elucidating the translational impact of increasing work capacity via HIFT may be of great interest to health and fitness practitioners ranging from strength/conditioning coaches to physical therapists.

Validity, Reliability, and Application of the Session-RPE Method for Quantifying Training Loads during High Intensity Functional Training
MDPI AG, 2018Co-Authors: Derek A. Crawford, Nicholas B. Drake, Michael J. Carper, Justin Deblauw, Katie M HeinrichAbstract:The session rate of perceived exertion method (sRPE) has often been utilized in sports activities in which quantification of external Training loads is challenging. The multi-modal, constantly varied nature of high intensity Functional Training (HIFT) represents a significant hurdle to calculate external work and the sRPE method may provide an elegant solution to this problem. However, no studies have investigated the psychometric properties of sRPE within HIFT interventions. Twenty-five healthy men and women participated in six weeks of HIFT. Rate of perceived exertion and heart rate were assessed within every Training session throughout the duration of the intervention. Compared to criterion heart rate-based measures, we observed sRPE method is a valid tool across individual, group, and sex levels. However, poor reliability in participants’ abilities to correctly match rate of perceived exertion with the relative level of physiologic effort (i.e., percentile of maximum heart rate) currently limits the utility of this strategy within HIFT. When applied, the validity and reliability of the sRPE seem to improve over time, and future research should continue to explore the potential of this monitoring strategy within HIFT interventions

the benefits of high intensity Functional Training fitness programs for military personnel
Military Medicine, 2016Co-Authors: Christopher K Haddock, Walker S C Poston, Katie M Heinrich, Sara A Jahnke, Nattinee JitnarinAbstract:ABSTRACTIntroduction. High intensity Functional Training (HIFT) programs are designed to address multiple fitness domains, potentially providing improved physical and mental readiness in a changing operational environment. Programs consistent with HIFT principals such as CrossFit, SEALFIT and the US Marine Corps' High Intensity Tactical Training (HITT) are increasingly popular among military personnel. The goal of HIFT programs is to produce high levels of cardiorespiratory fitness, endurance and strength that exceed those achieved by following current physical activity recommendations. Materials and Methods. Given the investment in and popularity of HIFT in the military, it is important to consider the potential impact of this approach to fitness Training for the health of military personnel and their risk of Training injury. In a previous report in this journal, we addressed the question of whether HIFT was associated with higher injury rates compared to other exercise programs. We argued that concerns ...

operative treatment of gartland type iii humeral supracondylar fractures in children with minimally invasive incision and percutaneous pinning
Chinese Journal of Reparative and Reconstructive Surgery, 2010Co-Authors: Xin Jiang, Xueyang Tang, Daoxi Wang, Mingxing Peng, Xiaoliang ChengAbstract:OBJECTIVE: To investigate the operative procedure and the therapeutic effects of minimally invasive incision and percutaneous pinning in operative treatment of Gartland type III humeral supracondylar fracture in children. METHODS: From September 2002 to July 2009, 189 patients with Gartland type III humeral supracondylar fracture were treated with minimally invasive incision and percutaneous pinning. There were 137 males and 52 females, aged from 1 to 13 years (6.2 years on average). Injury was caused by sports in 173 cases, by traffic accident in 9 cases, by falling from height in 5 cases, and by earthquake in 2 cases. All fractures were closed fractures, complicating others fracture in 11 cases, radial nerve injury in 36 cases, median nerve injury in 5 cases, ulnar nerve injury in 2 cases, and brachial artery injury in 2 cases. The time from injury to hospitalization was 1 hour to 10 days. Neurovascular repair was performed at the same period. RESULTS: All incisions healed by first intention, no related complications occurred. A total of 143 patients were followed up 5 months to 5 years (12 months on average). X-ray films showed fracture healed within 2-4 months (2.5 months on average). Cubitus varus occurred in 6 cases, but the functions of elbow flexion and extension were good; 2 cases were given distal humeral wedge osteotomy and 4 cases continued keeping the Functional Training. According to the Flynn et al criteria, the results were excellent in 121 cases, good in 15 cases, and fair in 7 cases; the excellent and good rate was 95.1%. Only a small incision scar was found, the function returned to normal in the cases complicated by nerve and blood vessel injury. CONCLUSION: Minimally invasive incision and percutaneous pinning for operative treatment of Gartland type III humeral supracondylar fracture in children is a safe and effective surgical procedure, which has minimal trauma, short surgery time, quick recovery, simple operation, and can be effective in reducing the complications.

spinal reflex activity a marker for neuronal Functionality after spinal cord injury
Neurorehabilitation and Neural Repair, 2012Co-Authors: Michèle Hubli, V Dietz, Marc BolligerAbstract:Background. Alterations in the function of spinal neuronal circuits underlying locomotion after a spinal cord injury (SCI) are associated with changes in the behavior of spinal reflexes (SRs) in both rats and humans. In healthy subjects, the SR consists of a dominant early reflex component, whereas in chronic, severely affected SCI subjects, a later component dominates. Objective. The aim of this study was to investigate the relationship between SR behavior and walking ability in para-/tetraplegic subjects. Method. The SR was evoked by nonnoxious tibial nerve stimulation. Walking ability was assessed by Functional tests and questionnaires. Results. There was a correlation between walking ability and SR behavior in chronic SCI: Severely affected SCI subjects unable to walk showed dominant late SR components, whereas in ambulatory SCI subjects an early SR component dominated. A Functional Training with an improvement of locomotor ability was accompanied by both a shift from a dominant to a smaller late and ...

rehabilitation of locomotion after spinal cord injury
Restorative Neurology and Neuroscience, 2010Co-Authors: Hubertus J A Van Hedel, V DietzAbstract:Advances in our understanding of the control of locomotion enable us to optimize the rehabilitation of patients with a spinal cord injury (SCI). Based on various animal models, it is generally accepted that central pattern generators (CPG) exists for the rhythmic generation of stepping movements, and that this is also the case in humans. However, in humans supraspinal control is also essential for the performance of locomotion. For regaining locomotor function, incomplete SCI subjects strongly depend on visual input to compensate for proprioceptive deficits and impaired balance. In addition, they require additional attentional capacity to stand, walk and handle their walking aids. These factors might contribute to their higher risk of falling. During the last decade, task-specific Functional Training performed by physiotherapists, combined with manual or robotic assisted bodyweight supported treadmill Training have improved the regaining of ambulatory function in patients with incomplete SCI. At present, there is no difference in effectiveness between these three types of Training. In the future, rehabilitation programs should be optimized to maximally exploit spontaneous and induced neural plasticity, leading to improved ambulation. To evaluate the efficacy of rehabilitation programs and of experimental treatments that might be translated from bench to bedside within the next few years, several objective assessments such as the 10 meter walk test and Walking Index for Spinal Cord Injury have been successfully introduced in the field of SCI rehabilitation.
