Objective:To assess the efficacy of lidocaine iontophoresis on myofascial trigger-point pain.Setting:University athletic training facility.Design:Randomized, double-blind, placebo-controlled, repeated-measures.Subjects:Twenty-three subjects with sensitive trigger points over the trapezius.Intervention:Placebo iontophoresis treatment without current or lidocaine, control treatment using distilled water and normal current dose, medicated treatment using 1% lidocaine and normal current dose.Main Outcome Measure:Trigger-point pressure threshold assessed with an algometer.Results:ANOVA revealed a significant difference among treatments (F2,40= 7.38,P< .01). Post hoc comparisons revealed a significant difference in pressure threshold between the lidocaine treatment and the control (P= .01) and placebo (P= .001) treatments. Effect sizes of .28 and .39, respectively, were found for these comparisons.Conclusions:Although the data revealed significant differences between treatments, the small effect sizes and magnitude of the pressure-sensitivity deviation scores suggest that iontophoresis with 1% lidocaine is ineffective in treating trigger points.

The Difference

Context:Overreaching can be beneficial, but there is a risk of overtraining.Objective:To investigate the difference in sleep efficiency between overreached and nonover-reached swimmers.Design:Repeated-measures, between-subjects. Swimmers were determined to be overreaching if 2 or more of their consecutive weekly swim times increased by 5% or more from baseline.Participants:9 competitive high school and university sprinter swimmers.Intervention:24-h wrist actigraph.Main Outcome Measure:Sleep efficiency as measured by the actigraph.Results:There was a significant difference in sleep efficiency on night 1 between the overreached and nonoverreached swimmers (P = .008), as well as in their times after averaging over all 5 trials and adjusting for baseline (P = .016). By the fourth swim trial, the overreached swimmers had significantly slower swim times than those of the nonoverreached swimmers (P = .001).Conclusions:Sleep efficiency shows potential as an objective, noninvasive predictor and monitor of overreaching in swimmers.

Context Arch tapings have been used to support the arch by increasing navicular height. Few researchers have studied navicular height and plantar pressures after physical activity. Objective To determine if taping techniques effectively support the arch during exercise. Design Crossover study. Setting Athletic training research laboratory. Patients or Other Participants Twenty-five individuals (13 men, 12 women; age = 20.0 ± 1.0 years, height = 172.3 ± 6.6 cm, mass = 70.1 ± 10.2 kg) with a navicular drop of more than 8 mm (12.9 ± 3.3 mm) volunteered. Intervention(s) All individuals participated in 3 days of testing, with 1 day for each tape condition: no tape, low dye, and navicular sling. On each testing day, navicular height and plantar pressures were measured at 5 intervals: baseline; posttape; and after 5, 10, and 15 minutes of running. The order of tape condition was counterbalanced. Main Outcome Measure(s) The dependent variables were navicular height in millimeters and plantar pressures in kilopascals. Plantar pressures were divided into 5 regions: medial forefoot, lateral forefoot, lateral midfoot, lateral rearfoot, and medial rearfoot. Separate repeated-measures analyses of variance were conducted for each dependent variable. Results Navicular height was higher immediately after application of the navicular-sling condition (P = .004) but was reduced after 5 minutes of treadmill running (P = .12). We observed no differences from baseline to posttape for navicular height for the low-dye (P = .30) and no-tape conditions (P = .25). Both the low-dye and navicular-sling conditions increased plantar pressures in the lateral midfoot region compared with the no-tape condition. The low-dye condition created decreased pressure in the medial and lateral forefoot regions compared with the no-tape condition. All changes were identified immediately after application and were maintained during running. No changes were noted in plantar pressures for the no-tape condition (P &gt; .05). Conclusions Both taping techniques effectively changed plantar pressures in the lateral midfoot, and these changes were sustained throughout the 15 minutes of exercise.

Background and Objectives: The purpose of the present study was to examine the effectiveness of dry needling as local treatment of upper trapezius trigger points related to chronic neck pain on pain and pain pressure threshold in women with chronic nonspecific neck pain. Methods: Thirty females with an active myofascial trigger point of the upper trapezius muscle were randomly divided into two groups: dry needling with passive stretch (n=15) and passive stretch alone (n=15). They received 5 sessions of the intervention for three weeks. The outcomes were pain intensity and pain pressure threshold. Every outcome was recorded at baseline and 2 days after the fifth session. Results: Significant improvement in pain and pain pressure threshold was observed in both groups (P=0.0001) after the treatment. The results of the independent t-test showed a significant difference in measurements between the dry needling and passive stretch groups (P<0.05). Conclusion: Dry needling with passive stretch can be more effective on pain and pain pressure threshold than passive stretching alone in short term in women with nonspecific neck pain.

Context:Rehabilitation adherence is accepted as a critical component for attaining optimal outcomes. Poor adherence is recognized as a problem in the athletic training setting. Measurement has been inconsistent, and no measure has been developed for athletic training settings.Objective:To identify indicators of sportinjury rehabilitation adherence relevant to athletic training and develop a Rehabilitation Adherence Measure for Athletic Training (RAdMAT) based on these indicators.Design:Mixed methods, 3 steps.Setting:College athletic training facility.Participants:Practicing certified athletic trainers (ATCs; n = 7) generated items, experts (n = 12) reviewed them, and practicing ATCs (n = 164) completed the RAdMAT for their most, average, and least adherent athlete.Main Outcome Measure:RAdMAT.Results:The RAdMAT is 16 items with 3 subscales. Subscales and total have good internal consistency and clearly discriminate among adherence levels.Conclusions:The RAdMAT is based on scholarly literature and clinical practice, making it particularly appropriate for use in athletic training clinical practice or for research purposes.

Objective:To explore predictors of recovery time.Design:Repeated measures on 4 occasions throughout recovery included injury appraisal, demographics, emotional responses, and psychological variables.Participants:Elite injured athletes (N= 136).Main Outcome Measure:Recovery time.Results:At all phases, being a team athlete was a significant predictor of faster recovery. At partial recovery (approximately one-third of the recovery time), significant predictors were active coping, confidence of reaching full recovery in the estimated time, not completing rehabilitation, and having less social support. By semirecovery (approximately two-thirds of the recovery time), vigor and using denial significantly predicted quicker recovery. At recovery, having previously suffered a serious nonsporting injury or illness, vigor, more confidence, and intensity of effort significantly predicted faster recovery.Conclusions:This study has expanded on and refined the work in this area and will help increase understanding of the role that psychological variables play in decreasing recovery time, which has important implications for those implementing rehabilitation programs.

AIM: To compare the corneal curvature and to investigate the agreement between three different keratometers. METHODS: In this prospective study, keratometry was performed using an IOL Master, a Bausch & Lomb manual keratometer and TOPCON KR-8800 autokeratometer on 252 eyes of patients recruited from camps for cataract surgery. The average keratometry values were recorded and compared. The agreements between the instruments were analyzed using the Bland Altman statistical method. The main outcome measure was average keratometry values.RESULTS: The mean corneal power was 44.62±1.52 D with the IOL Master, 44.60±1.52 D with the manual keratometer, and 44.46±1.53 D with the autokeratometer. The paired t test demonstrated a statistically significant difference in the mean corneal power between the IOL Master and manual keratometer (P=0.001), IOL Master and autokeratometer (P<0.0001), autokeratometer and manual keratometer (P<0.0001). The 95% limits of agreement (LoA) of the IOL Master and manual keratometer were -0.22 to 0.26; IOL Master and autokeratometer were -0.24 to 0.55; autokeratometer and manual keratometer were -0.30 to 0.57 as shown in the Bland-Altman plot. CONCLUSION: Keratometry data obtained with different instruments may not be interchangeable, a fact that has important implications for cataract surgeons with respect to both surgical planning and outcomes auditing.

Acromiohumeral Distance

Context:Compromise to the acromiohumeral distance (AHD) has been reported in subjects with subacromial impingement syndrome when compared with healthy subjects. In clinical practice, patients are taped with the intention of altering scapular position and influencing the AHD. However, research to determine the effects of taping on AHD is exiguous.Objectives:To evaluate the effect of ridged taping techniques to increase posterior scapular tilt and upward scapular rotation on the AHD.Design:1-group pretest/posttest repeated-measures design.Setting:Human performance laboratory.Participants:20 asymptomatic participants (10 male and 10 female) age 27 y (SD 8.0 y).Intervention:Ridged tapping of the scapula into posterior tilt and upward scapular rotation.Main Outcome Measure:Ultrasound measurement of the AHD.Results:AHD increased significantly after rigid tape application to the scapula (P < .003) in healthy shoulders in 60° of passive arm abduction.Conclusion:Taping techniques applied to the scapula had an immediate effect of increasing the AHD in healthy shoulders in 60° of passive arm abduction. Results suggest that taping for increasing posterior scapular tilt and increasing scapular upward rotation can influence the AHD and is a useful adjunct to rehabilitation in patients with subacromial impingement syndrome.
