To evaluate the effects of joint mobilization, in which movement is applied to the ankle's dorsiflexion range of motion, on dynamic postural control and on the self-reported instability of patients with chronic ankle instability (CAI). A double-blind, placebo-controlled, randomized trial with repeated measures and a follow-up period. Ninety patients with a history of recurrent ankle sprain, self-reported instability, and a limited dorsiflexion range of motion, were randomly assigned to either the intervention group (Joint Mobilizations, 3 weeks, two sessions per week) the placebo group (Sham Mobilizations, same duration as joint mobilization) or the control group, with a 6 months follow-up. Dorsiflexion Range of Motion (DFROM), Star Excursion Balance Test (SEBT) and CAI Tool (CAIT) were outcome measures. A separate 3 × 4 mixed model analysis of variance was performed to examine the effect of treatment conditions and time, and intention-to-treat (ITT) analysis was applied to evaluate the effect of the independent variable. The application of joint mobilization resulted in better scores of DFROM, CAIT, and SEBTs in the intervention group when compared with the placebo or the control groups (p < 0.001). The effect sizes of group-by-time interaction, measured with eta-squared, oscillated between 0.954 for DFROM and 0.288 for SEBT posteromedial distance. In within-group analysis, the manipulation group showed an improvement at 6 months follow-up in CAIT [mean = 5.23, CI 95% (4.63-5.84)], DFROM [mean = 6.77, CI 95% (6.45-7.08)], anterior SEBT [mean = 7.35, CI 95% (6.59-8.12)], posteromedial SEBT [mean = 3.32, CI 95% (0.95-5.69)], and posterolateral SEBT [mean = 2.55, CI 95% (2.20-2.89)]. Joint mobilization techniques applied to subjects suffering from CAI were able to improve ankle DFROM, postural control, and self-reported instability. These results suggest that joint mobilization could be applied to patients with recurrent ankle sprain to help restore their functional stability. Implications for Rehabilitation Functional instability is a very common sequela in patients with CAI, resulting in reduced quality of living due to the limitations it imposes on daily life activities. The mobilization with movement technique presented by Mulligan, and based on the joint mobilization accompanied by active movement, appears as a valuable tool to be employed by physical therapists to restore ankle function after a recurrent ankle sprain history. ROM restriction, subjective feeling of instability and dynamic postural control are benefiting from the joint mobilization application.

To assess the effectiveness of 12 weeks of Pilates practice on disability, pain and kinesiophobia in patients with chronic non-specific low back pain. This is a randomized controlled trial. This study was conducted in the university laboratory. A total of 64 participants with chronic non-specific low back pain were included. Participants were randomly allocated to intervention group consisted in Pilates intervention during 12 weeks (n = 32) or control group who received no treatment (n = 32). Disability, pain and kinesiophobia were assessed by Roland Morris Disability Questionnaire, visual analogue scale and Tampa Scale of Kinesiophobia, respectively. Measurements were performed at baseline, at 6 and 12 weeks after study completion. There were significant differences between groups with observed improvement in Pilates intervention group in all variables after treatment (P < 0.001). Major changes on disability and kinesiophobia were observed at six weeks of intervention with no significant difference after 12 weeks (P < 0.001). Mean changes of the intervention group compared with the control group were 4.00 (0.45) on the Roland Morris Disability Questionnaire and 5.50 (0.67) in the Tampa Scale of Kinesiophobia. Pain showed better results at six weeks with a slightly but statistically significant improvement at 12 weeks with Visual Analogue Scale scores of 2.40 (0.26) (P < 0.001). Pilates intervention in patients with chronic non-specific low back pain is effective in the management of disability, pain and kinesiophobia.

The objective of the present study was to determine the effectiveness of a 6-week balance training program on patients with Chronic Ankle Instability (CAI) in relation to the results obtained in Dynamic Balance, subjective feeling of instability and pain using a single-blind randomized controlled trial. 70 athletes were randomly assigned to control or intervention group. The control group performed their usual training, and the intervention group was administered the same usual activity in addition to a balance program. The paired t-test was performed to evaluate the change scores in each group. The t-test for independent samples was performed to evaluate between-group differences in change scores. Significance level was assigned for p-values less than 0.05 for all analyses. There were significant differences between groups in change scores in CAIT and all of the SEBTs reach distances (p<0.001) but not in Pain (p=0.586). The effect sizes were larger for the outcomes measures that showed significant differences. In the within-group change, the experimental groups showed larger effect sizes in CAIT, SEBT posteromedial and SEBT posterolateral, and moderate effect sizes in SEBT anterior. Exercise therapy training based on multi-station balance tasks led to significant improvements in dynamic balance and self-reported sensation of instability in patients with CAI.
