- Objective To investigate the effects of local vibration on muscle strength in healthy adults.Data sources The electronic databases PubMed, CINAHL, Scopus and Web of Science were searched using a combination of the following keywords: vibration, vibration therapy, power, maximal voluntary contraction, performance, rate of force development and vibratory exercise. In addition, the Medical Subject Headings 'vibration', 'strength' and 'exercise' were used. The bibliographical search was limited to articles published in English.Study selection Trials that evaluated the effect of localised vibration on muscle strength in healthy humans were included.Data extraction Two independent evaluators verified the quality of the selected studies using the PEDro Scale and the Cochrane Collaboration's tool for assessing the risk of bias. Muscle strength was calculated for each intervention.Results In total, 29 full-text studies were assessed for eligibility. Eighteen studies did not match the inclusion criteria, and were excluded. The 11 studies included in this review had an average PEDro score of 5.36/10. Most of the studies reported significant improvements in muscle strength after the application of local vibration. There was considerable variation in the vibration training parameters and target muscle location.Conclusions The use of local vibration on the target muscle can enhance muscle strength in healthy adults. Further well-designed controlled studies are required to confirm the effect of local vibration training on muscle strength.

- Background Several studies have reported the effects of whole body vibration (WBV) training on muscle strength. This systematic review investigates the current evidence regarding the effects of WBV training on quadriceps muscle strength in individuals with knee osteoarthritis (OA). Data sources We searched PubMed, CINAHL, Embase, Scopus, PEDro, and Science citation index for research articles published prior to March 2015 using the keywords whole body vibration, vibration training, strength and vibratory exercise in combination with the Medical Subject Heading 'Osteoarthritis knee'. Study selection This meta-analysis was limited to randomized controlled trials published in the English language. Data extraction The quality of the selected studies was assessed by two independent evaluators using the PEDro scale and criteria given by the International Society of Musculoskeletal and Neuronal Interactions (ISMNI) for reporting WBV intervention studies. The risk of bias was assessed using the Cochrane collaboration's tool for domain-based evaluation. Isokinetic quadriceps muscle strength was calculated for each intervention. Results Eighteen studies were identified in the search. Of these, four studies met the inclusion criteria. Three of these four studies reached high methodological quality on the PEDro scale. Out of the four studies, only one study found significantly greater quadriceps muscle strength gains following WBV compared to the control group. Conclusions In three of the four studies that compared a control group performing the same exercise as the WBV groups, no additional effect of WBV on quadriceps muscle strength in individuals with knee OA was indicated.

- Objectives The heel-rise test is used to assess the strength and endurance of the plantar flexors in everyday clinical practice. However, several factors may affect outcomes, including sex, age, body mass index and activity level. The aims of this study were to revisit the reliability and normative values of this test, and establish normative equations accounting for several factors. Interventions Subjects performed single-legged heel rises to fatigue, standing on a 10 degrees incline, once on each leg. A subset of subjects (n = 32) repeated the test 1 week later. Reliability was quantified using intraclass (ICC) correlation coefficients and BlandAltman plots {mean difference [95% limits of agreement (LOA)]}, whereas the impact of sex, age, body mass index and activity level on the number of heel rises was determined using non-parametric regression models. Results The test showed excellent reliability (ICC = 1.0 right leg, 1.0 left leg), with mean between-day differences in the total number of heel-rise repetitions of 0.2 (95% LOA -6.2 to 6.5) and 0.1 (95% LOA -6.1 to 6.2) for right and left legs, respectively. Overall, males completed more repetitions than females (median 24 vs 21). However, older females (age >60 years) outperformed older males. According to the model, younger males with higher activity levels can complete the most heel rises. Conclusions The heel-rise test is highly reliable. The regression models herein can be employed by clinicians to evaluate the outcomes of heel-rise tests of individuals against a comparable normative population.

- OBJECTIVES: Patients undergoing lung cancer surgery are routinely offered physiotherapy. Despite its routine use, effects on postoperative physical recovery have yet not been demonstrated. The aim of this study was to investigate whether physiotherapy could improve postoperative in-hospital physical activity level and physical capacity.DESIGN: Single-blind randomized controlled trial.SETTING: Thoracic surgery department at a University Hospital.PARTICIPANTS: Patients undergoing elective thoracic surgery (n=94) for confirmed or suspected lung cancer were assessed during hospital stay.INTERVENTION: Daily physiotherapy, consisting of mobilization, ambulation, shoulder exercises and breathing exercises. The control group received no physiotherapy treatment.OUTCOMES: In-hospital physical activity assessed with the Actigraph GT3X+ accelerometer, six-minute walk test, spirometry and dyspnea scores.RESULTS: The treatment group reached significantly more accelerometer counts (2010 (1508) vs 1629 (1146), mean difference 495 [95% CI 44 to 1109]), and steps per hour (49 (47) vs 37 (34), mean difference 14 [95% CI 3 to 30]), compared to the control group, during the first three postoperative days. No significant differences in six-minute walk test (percent of preoperative 71% vs 79%, P=0.13), spirometry (FEV1 percent of preoperative 69% vs 69%, P=0.83) or dyspnoea (M-MRC 2 vs 2, P=0.74) between the groups were found.CONCLUSIONS: Patients receiving in-hospital physiotherapy showed increased level of physical activity during the first days after lung cancer surgery, compared to an untreated control group. However, no effects on the six-minute walk test or spirometric values were found. The clinical importance of an increased physical activity level during the early postoperative period needs to be further evaluated.CLINICAL TRIAL REGISTRATION NUMBER: NCT01961700.
