Beneficial Intervertebral Disc and Muscle Adaptations in High-Volume Road Cyclists.
2018
Purpose Cycling is widely practiced as a mode of transportation, a leisurely pursuit, and a competitive sport. Approximately half of cyclists experience low back pain. Yet, there has been limited study of spine tissue adaptations due to cycling.Methods To investigate potential risk factors for spinal pain, we compared 18 high-volume cyclists (>150 kmwk(-1) for 5 yr) to 18 height-matched nonsporting referents. Participants had no history of spinal pathology. Magnetic resonance imaging was used to quantify intervertebral disc (IVD) morphology and hydration, and psoas, erector spinae, quadratus lumborum, and multifidus muscle size and fat content. Endurance of trunk muscles (flexors and extens…
Impact of Visual Biofeedback of Trunk Sway Smoothness on Motor Learning during Unipedal Stance.
2020
The assessment of trunk sway smoothness using an accelerometer sensor embedded in a smartphone could be a biomarker for tracking motor learning. This study aimed to determine the reliability of trunk sway smoothness and the effect of visual biofeedback of sway smoothness on motor learning in healthy people during unipedal stance training using an iPhone 5 measurement system. In the first experiment, trunk sway smoothness in the reliability group (n = 11) was assessed on two days, separated by one week. In the second, the biofeedback group (n = 12) and no-biofeedback group (n = 12) were compared during 7 days of unipedal stance test training and one more day of retention (without biofeedback…
Performance in dynamic movement tasks and occurrence of low back pain in youth floorball and basketball players
2020
Abstract Background Prospective studies investigating risk factors for low back pain (LBP) in youth athletes are limited. The aim of this prospective study was to investigate the association between hip-pelvic kinematics and vertical ground reaction force (vGRF) during landing tasks and LBP in youth floorball and basketball players. Methods Three-hundred-and-eighty-three Finnish youth female and male floorball and basketball players (mean age 15.7 ± 1.8) participated and were followed up on for 3 years. At the beginning of every study year the players were tested with a single-leg vertical drop jump (SLVDJ) and a vertical drop jump (VDJ). Hip-pelvic kinematics, measured as femur-pelvic angl…
A successful backward step correlates with hip flexion moment of supporting limb in elderly people.
2018
Purpose The objective of this study was to determine the positional relationship between the center of mass (COM) and the center of pressure (COP) at the time of step landing, and to examine their relationship with the joint moments exerted by the supporting limb, with regard to factors of the successful backward step response. Methods The study population comprised 8 community-dwelling elderly people that were observed to take successive multi steps after the landing of a backward stepping. Using a motion capture system and force plate, we measured the COM, COP and COM-COP deviation distance on landing during backward stepping. In addition, we measured the moment of the supporting limb joi…
The Role of Textured Material in Supporting Perceptual-Motor Functions
2013
Simple deformation of the skin surface with textured materials can improve human perceptual-motor performance. The implications of these findings are inexpensive, adaptable and easily integrated clothing, equipment and tools for improving perceptual-motor functionality. However, some clarification is needed because mixed results have been reported in the literature, highlighting positive, absent and/or negative effects of added texture on measures of perceptual-motor performance. Therefore the aim of this study was to evaluate the efficacy of textured materials for enhancing perceptual-motor functionality. The systematic review uncovered two variables suitable for sub-group analysis within …
Evaluation of impact-shock on gait after the implementation of two different training programs in older adults
2020
Abstract Background Gait is negatively affected with increasing age. It is widely accepted that training produces physical-functional improvements in older adults, which can be assessed with numerous physical-functional tests. However, very few studies have been carried out using accelerometry to analyse the training effect on kinetic and kinematic variables in older adults, and there is no one that investigate the effects of two different training programs. Therefore, the aim of this study is to analyse the effects of an interval-walking program and a multicomponent program on the acceleration impacts, shock attenuation, step-length, stride frequency, and gait speed in older adults. Method…
Does single-event multilevel surgery enhance physical functioning in the real-life environment in children and adolescents with cerebral palsy (CP)?:…
2013
Orthopedic procedures are a method of treating gait deviations and musculoskeletal pathology that develop with age in cerebral palsy (CP). Recently single-event multilevel surgery (SEMLS) has become common practice. Although there is evidence that SEMLS could improve gait, it is unclear whether it will enhance overall physical functioning and coping strategies in the real-life environment. It is unclear how improved walking capacity affects actual functioning and enables greater independence. The aim of this study was to examine the perceptions of adolescents concerning the results of surgery on personal physical functioning in the environment five or more years after SEMLS. In this study, …
A one-year proprioceptive exercise programme reduces the incidence of falls in community-dwelling elderly people: A before-after non-randomised inter…
2016
Abstract Background The risk of falls increases with age. Balance alteration and polypharmacy are independent contributors to an increased risk of falls. Objective The primary aim was to assess whether a proprioceptive exercise programme reduces the incidence of falls. A secondary aim was to assess the association between drugs and falls. Design This was a before–after non-randomised intervention study. Participants The study recruited independent and cognitively intact community-dwelling people aged over 69 years, from December 2012 to May 2014. Methods The intervention was done by a nurse and consisted of a monthly supervised group session of proprioceptive training for 1 year, supplement…
Activity of Thigh Muscles During Static and Dynamic Stances in Stroke Patients: A Pilot Case-Control Study
2014
Impaired postural control is a key characteristic of mobility problems in stroke patients and has great impact on the incidence of falls and on the level of independence in activities of daily living. The role played by the thigh muscles in balance impairment in stroke patients has not been sufficiently investigated. This study investigated the activities of the thigh muscles in stroke patients during standing balance manipulations.Ten stroke patients and 15 healthy subjects performed 5 upright standing tasks on a force platform: normal standing with eyes open, normal standing with eyes closed, feet together, semi-tandem standing, and a dynamic measurement along a predefined route. The post…
Sense of coherence: effect on adherence and response to resistance training in older people with hip fracture history.
2013
Our aim was to study the effects of sense of coherence (SOC) on training adherence and interindividual changes in muscle strength, mobility, and balance after resistance training in older people with hip fracture history. These are secondary analyses of a 12-week randomized controlled trial of progressive resistance training in 60- to 85-year-old community-dwelling people 0.5–7 years after hip fracture (n = 45; ISRCTN34271567). Pre- and posttrial assessments included SOC, knee extension strength, walking speed, timed up-and-go (TUG), and Berg Balance Scale (BBS). Group-by-SOC interaction effects (repeated-measures ANOVA) were statistically significant for TUG (p = .005) and BBS (p = .040), …
