2007
Abstract Tarnanen SP, Ylinen JJ, Siekkinen KM, Malkia EA, Kautiainen HJ, Hakkinen AH. Effect of isometric upper-extremity exercises on the activation of core stabilizing muscles. Objective To evaluate whether isometric exercises for the upper extremities could sufficiently activate core stabilizing muscles to increase muscle strength. Design Cross-sectional study. Setting Department of physical medicine and rehabilitation at a Finnish hospital. Participants Healthy adult women (N=20). Interventions Not applicable. Main Outcome Measures Peak isometric strength of the back and abdominal muscles was measured and relative loading in 5 test exercises was evaluated by surface electromyography. Re…
The prevalence of musculoskeletal pain and use of painkillers among adolescent male ice hockey players in Finland
2014
Participating in competitive sport increases the risk for injuries and musculoskeletal pain among adolescent athletes. There is also evidence that the use of prescription drugs has increased among sport club athletes. The purpose of this study was to evaluate the use of painkillers among young male ice hockey players (IHP) in comparison to schoolboys (controls) and its relation to the prevalence of musculoskeletal pain and problems during activities and sleeping. Information was gathered through a questionnaire, completed by 121 IHP and compared to the responses of 618 age-matched controls. Results showed that monthly existing pain was at 82% for IHP, and 72% for controls, though IHP had st…
Core muscle activation during dynamic upper limb exercises in women.
2012
Although several everyday functions and sporting activities demand controlled use of the abdominal and back muscles while working with the upper limbs, the activity of core muscles during dynamic upper limb exercises in the standing position has not been studied extensively. The purpose of this cross-sectional study was to examine abdominal and back muscle activity during dynamic upper limb exercises while standing and to evaluate whether dynamic exercises are appropriate for strengthening muscles. The activation of the rectus abdominis, obliquus externus abdominis, longissimus, and multifidus muscles during dynamic bilateral or unilateral shoulder exercises with or without fixation of the …
Test-retest repeatability of questionnaire for pain symptoms for school children aged 10–15 years
2019
Abstract Background and aims There is a growing body of evidence, that pain is common at school age. Less is known about the repeatability of pain questionnaires for children. This study aimed to assess the test-retest repeatability of the Finnish version of the electronic pain questionnaire for school-aged children. Methods Primary (n = 79) and lower secondary (n = 127) schoolchildren aged 10–15 years from two schools from the Jyväskylä region of Finland, filled in an electronic questionnaire twice in an interval of 2 weeks. It captured the frequency of pain symptoms with a five-point Likert-scale questionnaire covering nine areas of the body for the last 3 months. The intraclass correlati…
