“…Our finding that only the BFR+R led to a significant improvement in timed performance during the SHT supports our hypothesis. This finding is consistent with that of a previous study by Yoshida et al (2018) who reported long performance time (worse) of the involved limb during the SHT and a delayed muscle activity of fibularis longus, tibialis anterior, and gastrocnemius muscles in patients with ankle sprain. The explanation for such improvement is unclear, but it may be related to greater strength gains in the BFR+R versus the R program.…”

Blood flow restriction (BFR) resistance exercise has been advocated as an alternative approach for improving muscle strength in patients undergoing musculoskeletal rehabilitation. The present study aimed to evaluate the effectiveness of a 4-week supervised rehabilitation (R) with and without BFR on muscle strength, cross-sectional area (CSA), dynamic balance, and functional performance in athletes with chronic ankle instability (CAI). A total of 16 collegiate athletes with CAI participated in this study. They were randomly assigned to the BFR+R group (n=8) or the R group (n=8). Both groups underwent supervised rehabilitation 3 times weekly for 4 consecutive weeks. Additionally, the BFR+R group was applied with a cuff around the proximal thigh at 80% arterial occlusion pressure in addition to the traditional rehabilitation program, whereas the R group received the sham BFR only. Before and after 4 weeks of intervention, isokinetic muscle strength, CSA, Y-balance test, and side hop test (SHT) were measured. Following a 4-week intervention, the BFR+R group exhibited significant improvements in muscle strength of ankle plantarflexor and evertor, CSA of fibularis longus, and SHT timed performance compared with prior training and the R group (all, P<0.05). However, no significant difference was observed on dynamic balance among the groups. The present finding indicated that a 4-week supervised rehabilitation combined with BFR is more effective in improving muscle strength and size and functional performance compared with the traditional rehabilitation alone. This information could have implications for physical therapists and clinician in developing and designing a rehabilitation program for athletes with CAI.

“…The FADI was examined as a measure of foot and ankle functional restriction in CAI because persons with CAI typically complain about their ankles giving way during functional tasks. [ 26 ] Our finding that BFR + R and R resulted in a significant improvement in FADI outcome measures contradicts the findings of Yoshida et al, [ 27 ] who found that patients with ankle sprain had a prolonged performance time of the affected leg and delayed muscle activation of the fibularis longus, tibialis anterior, and gastrocnemius muscles. In our study, the cause of this gain could be linked to stronger ankle plantar flexor and evertor muscles in the BFR + R and R than the BFR alone.…”

Background: Blood Flow Restriction (BFR) training has gained popularity as a novel training strategy in athletes and rehabilitation settings in recent years. Objective: To investigate whether BFR as a stand-alone treatment would affect muscle strength, dynamic balance, and physical function in female patients with chronic ankle instability (CAI). Methods: Thirty-nine patients with CAI were randomly allocated into 1 of 3 groups: BFR as a stand-alone (BFR) group, BFR with rehabilitation (BFR+R) group, and rehabilitation (R) group. All groups trained 3 times per week for 4 weeks. One week before and after the intervention, strength of muscles around ankle joint, 3 dynamic balance indices: Overall Stability Index, Anterior-Posterior Stability Index, and Medial-Lateral Stability Index, and physical function were assessed via an isokinetic dynamometer, the Biodex Balance System, and the Foot and Ankle Disability Index, respectively. Results: The strength of muscles around ankle and dynamic balance indices improved significantly in BFR + R and R groups (P < .006), but not in BFR group (P > .006). All dynamic balance indices showed improvement in BFR + R and R groups except the Medial-Lateral Stability Index (P > .006). Foot and Ankle Disability Index increased significantly in BFR + R and R groups (P < .006), however; no improvement occurred in BFR group (P > .006). Conclusions: The BFR as a stand-alone treatment hasn’t the ability to improve the strength of muscles around the ankle, dynamic balance, and physical function in females with CAI compared to the BFR + R or the R program. In addition, the strength of muscles around the ankle correlated significantly with both dynamic balance and physical function in BFR + R and R groups.

“…Although the SHT is one of the most widely used functional test to assess ankle stability and has undergone the most research (Ortiz et al, 2005) in relation to lower limb functional performance (Gustavsson et al, 2006), there is still a lack of knowledge addressing the issue of the measurement characteristics of SHT. Stopwatches are up to date the most commonly used to measure the SHT performance (Docherty et al, 2005;Ortiz et al, 2005;Ortiz et al, 2011;Yoshida et al, 2011;Yoshida et al, 2018;Kamonseki et al, 2018), the measurement characteristics of mentioned test could be questionable. Alternative to stopwatch could be the contact matt which allows not only more reliable measures (Garcia-Lopez et al, 2005) but also the measurement of duration of every single phase of SHT, i.e., medial and lateral contact and "flight" times.…”

Evaluation of the Limb Symmetry Index: The Side Hop Test

The main objective of present study was to evaluate inter-rater reliability and concurrent validity of Side Hop Test stopwatch vs. force plates timing, and to determine the number of sessions and trials required to minimize the effects of learning on Side Hop Test total time and limb symmetry index. Fifteen healthy male physical education students (mean ± SD: age, 23 ± 3 years; height, 181 ± 9 cm; and weight 72 ± 6 kg) participated. Side Hop Test total time (stopwatch and force plates) of left and right leg, and limb symmetry index (force plates) were obtained over seven sessions conducted 5–7 days apart. Time recordings of two raters were similar (t = −0.56, p > 0.05) with high reliability (all ICC >0.99 and CV% <0.1) and no systematic bias when compared to force plate data (p > 0.05; for rater 1 and 2, respectively). Total time improved across the Sessions (F = 25.87, p < 0.01, ω2 = 0.18) and Trials (F = 68.15, p < 0.01, ω2 = 0.10), with no significant interaction between factors. No between-leg differences were detected (F = 0.52, p > 0.05, ω2 = 0.001). Limb symmetry index ranged from 0.999 to 1.055 across all sessions and trials (all p > 0.05 and ω2 < 0.00). Due to low coefficient of correlation, high interclass correlation coefficient, and the lack in heteroscedasticity, stopwatch measurements are valid to measure total time in the Side Hop Test. Moreover, stopwatch measurements could be reliably used to measure total time in the Side Hop Test, while the test could be administrated with only one experienced rater. Unlike total times, findings on limb symmetry index suggest it could be reliably assessed after seven familiarization sessions.
