RSWT was successful in the treatment of chronic PF even when only two sessions with 2,000 impulses each were performed 1 week apart.

Shoulder disorders attributed to weight training are well documented in the literature; however, a paucity of evidence-based research exists to describe risk factors inherent to participation. Shoulder joint and muscle characteristics in the recreational weight training (RWT) population were investigated to determine specific risk-related adaptations that may occur from participation. Ninety participants, men between the ages of 19 and 47 (mean age 28.9), including 60 individuals who participated in upper-extremity RWT and 30 controls with no record of RWT participation, were recruited. Active range of motion (AROM), posterior shoulder tightness (PST), body weight-adjusted strength values, and agonist/antagonist strength ratios were compared between the RWT participants and the control group. Statistical analysis identified significant differences (p < 0.001) between the groups when analyzing shoulder mobility. The RWT participants had decreased mobility when compared with the control group for all AROM measurements except external rotation, which was greater. Strength ratios were significantly greater in the RWT group when compared with the control group (p

Thoracic spine manipulation has been shown to be effective for the management of neck pain. The purpose of this study was to investigate the immediate effect of a T3-T4 spinal thrust manipulation on autonomic nervous system activity in subjects with chronic cervical pain. An additional aim was to determine if the manipulation resulted in an immediate pain relief in patients with chronic neck pain when compared to a placebo intervention. One hundred subjects with chronic neck pain were randomly assigned to receive either a thoracic thrust manipulation or a placebo intervention. The Friedman's test was used to evaluate the change in pupil diameter within both groups. The Wilcoxen signed-ranks test was used to explore pupil changes over time and to make paired comparisons of the pupil change between the groups. The MannWhitney U test was used to compare the change in pain perception for the chronic cervical pain group subjects receiving either the thrust manipulation or the placebo intervention. The results demonstrated that manipulation did not result in a change in sympathetic activity. Additionally, there was no significant difference in the subject's pain perception (P50.961) when comparing the effects of the thrust manipulation to the placebo intervention within this group of subjects with chronic neck pain. The clinical impression of this study is that manipulation of the thoracic spine may not be effective in immediately reducing pain in patients with chronic neck pain.

The popularity of resistance training (RT) is evident by the more than 45 million Americans who engage in strength training regularly. Although the health and fitness benefits ascribed to RT are generally agreed upon, participation is not without risk. Acute and chronic injuries attributed to RT have been cited in the epidemiological literature among both competitive and recreational participants. The shoulder complex in particular has been alluded to as one of the most prevalent regions of injury. The purpose of this manuscript is to present an overview of documented shoulder injuries among the RT population and where possible discern mechanisms of injury and risk factors. A literature search was conducted in the PUBMED, CINAHL, SPORTDiscus, and OVID databases to identify relevant articles for inclusion using combinations of key words: resistance training, shoulder, bodybuilding, weightlifting, shoulder injury, and shoulder disorder. The results of the review indicated that up to 36% of documented RT-related injuries and disorders occur at the shoulder complex. Trends that increased the likelihood of injury were identified and inclusive of intrinsic risk factors such as joint and muscle imbalances and extrinsic risk factors, namely, that of improper attention to exercise technique. A majority of the available research was retrospective in nature, consisting of surveys and descriptive epidemiological reports. A paucity of research was available to identify predictive variables leading to injury, suggesting the need for future prospective-based investigations.

Purpose: The purpose of this study was to evaluate the face and content validity of a modified self-report questionnaire adapted from previous studies’ questionnaires. The modified questionnaire will be used in a later study to assess the effect of online learning on behaviors, attitudes, and clinical practices of physical therapists in the United States regarding evidence-based clinical practice. Methods: An expert panel of nine physical therapists in the field of evidence-based practice reviewed and rated the modified instrument for the relevance and representativeness of each item based on a dichotomous rating of favorable or unfavorable. Their ratings were used to calculate the content validity index values of each final item. Items with content validity index (CVI) greater than 0.78 were included in the final instrument. Results: The final instrument contained 23 Likert-type scale multiple choice questions and 13 dichotomous “yes” or “no” response options, and 13 are ranked response options categorized under eight thematic domains designed to address the effect of internet use and online information resource use on evidence-based practice among physical therapists in the United States. Demographic and practice data were also collected. Conclusion: The preliminary findings support the face and content validity of this 59-item questionnaire pending further validation for construct and criterion validity.

Numerous randomized controlled trials (RCTs) demonstrated efficacy and safety of extracorporeal shock wave therapy (ESWT) for chronic plantar fasciopathy (cPF). However, only two such RCTs investigated a follow-up period of more than 1 year, both applying focused ESWT. Corresponding data for radial ESWT (rESWT) have not yet been reported. We therefore tested the hypothesis that rESWT is effective and safe for the management of cPF with long-term follow-up of 2 years. To this end n = 50 patients with cPF were randomly allocated to either two sessions of rESWT (one session per week; 2,000 shock waves with energy flux density of 0.16 mJ/mm per session) (n = 25) or to placebo treatment (n = 25). Evaluation was by change in Visual Analog Scale (VAS) score and Roles and Maudsley (RM) score. Mean pretreatment VAS scores for the rESWT and placebo groups were 8.5 and 8.9, respectively. 1, 3, 6, 12, and 24 months after treatment, the mean VAS scores for the rESWT and placebo groups were 0.6, 1.1, 0.5, 2.3, and 1.4 and 7.6, 7.7, 7.4, 6.9, and 5.6 (p < 0.001), respectively. Differences in mean RM scores were statistically significant between groups at 1, 3, 6, 12, and 24 months post treatment, but not at baseline. There were no significant complications. These data indicate that rESWT is effective and safe for the management of cPF with long-term follow-up of 2 years. © 2016 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
