Context:

Posterior shoulder tightness (PST) and glenohumeral internal-rotation deficit (GIRD) can contribute to shoulder pain suffered by athletes engaged in overhead sporting activities. Stretching is a common intervention to resolve PST and GIRD, but it has weak evidence of effectiveness to date.

Objective:

This systematic review aimed to collect and synthesize effectiveness data from English- and Japanese-language randomized controlled trials (RCTs) investigating stretching interventions for PST and GIRD.

Evidence Acquisition:

7 English databases and 3 Japanese databases were searched from inception until December 5, 2015. Only English- and Japanese-language RCTs were considered. Risk of bias in the included studies was assessed using the Physiotherapy Evidence Database scale. Data were synthesized qualitatively.

Evidence Synthesis:

Eight English-language and 2 Japanese-language papers of low to high quality were included. There was moderate evidence for positive immediate and short-term effects of cross-body stretch on PST and GIRD in asymptomatic young subjects. Moderate evidence was found to suggest that active sleeper stretch might not be more effective than no intervention to improve PST and GIRD in the short term.

Conclusions:

Cross-body stretch can be effective to improve PST and GIRD in asymptomatic young subjects immediately or in the short term. Further study with methodological rigor is necessary to investigate the long-term effectiveness of stretching interventions on PST and GIRD in symptomatic patients.

Background:

Less than half of U.S. adults engage in the recommended amount of physical activity (PA). Internet-delivered PA programs increase short-term PA but long-term adherence is largely equivocal.

Purpose:

To determine whether increased PA following the 16-week internet-delivered Active Living Every Day (ALED-I) program is maintained 8 months later in sedentary and overweight rural adults.

Methods:

In our previous randomized controlled trial (N = 32; 18 intent-to-treat controls, 14 ALED-I interventions), the ALED-I group increased PA (+1384 steps/day; E.S. = 0.95) and reduced central adiposity. Nine original intervention participants and ten delayed intent-to-treat control participants completed ALED-I and an 8-month follow-up. Pedometer-measured PA, anthropometric variables, and cardiometabolic disease risk factors were assessed at baseline, postintervention, and at 8 months.

Results:

Control crossover participants increased PA (+1337 steps/day; P = .04). Eight months following completion of ALED-I (N = 19), PA levels relapsed (–1340 steps/day) and were similar to levels before the intervention (6850 ± 471 steps/day vs. 6755 ± 543 steps/day; P = .89). Total cholesterol and triglycerides improved, –9.9% and –18.2%, respectively, and reductions in central adiposity were maintained (97.1 ± 2.2 cm vs. 97.2 ± 2.2 cm; P = .66).

Conclusions:

The ALED-I intervention was efficacious in the short-term but did not produce longer-term adherence to PA. Future theory- based internet-delivered interventions that produce habituation of increased PA are warranted. Study conducted in Laramie, WY from January 2007 through November 2007.

Context:

Both balance training and selected interventions meant to target sensory structures (STARS) have been shown to be effective at restoring deficits associated with chronic ankle instability (CAI). Clinicians often use multiple treatment modalities in patients with CAI. However, evidence for combined intervention effectiveness in CAI patients remains limited.

Objective:

To determine if augmenting a balance-training protocol with STARS (BTS) results in greater improvements than balance training (BT) alone in those with CAI.

Design:

Randomized-controlled trial.

Setting:

Research laboratory.

Patients:

24 CAI participants (age 21.3 ± 2.0 y; height 169.8 ± 12.9 cm; mass 72.5 ± 22.2 kg) were randomized into 2 groups: BT and BTS.

Interventions:

Participants completed a 4-week progression-based balance-training protocol consisting of 3 20-min sessions per week. The experimental group also received a 5-min set of STARS treatments consisting of calf stretching, plantar massage, ankle joint mobilizations, and ankle joint traction before each balance-training session.

Main Outcome Measures:

Outcomes included self-assessed disability, Star Excursion Balance Test reach distance, and time-to-boundary calculated from static balance trials. All outcomes were assessed before, and 24-hours and 1-week after protocol completion. Self-assessed disability was also captured 1-month after the intervention.

Results:

No significant group differences were identified (P > .10). Both groups demonstrated improvements in all outcome categories after the interventions (P < .10), many of which were retained at 1-week posttest (P < .10). Although 90% CIs include zero, effect sizes favor BTS. Similarly, only the BTS group exceeded the minimal detectable change for time-to-boundary outcomes.

Conclusions:

While statistically no more effective, exceeding minimal detectable change scores and favorable effect sizes suggest that a 4-week progressive BTS program may be more effective at improving self-assessed disability and postural control in CAI patients than balance training in isolation.

Study Design A randomized controlled trial was designed to compare the effects of TCC and BW exercises on balance with SLS during a 16-week training program. Both TCC and BW groups participated in a 60-min moderate-intensity intervention exercise for at least five sessions weekly for 16 weeks. Balance
