“…Based on a previous study for postural stability in patients with ankle instability [25,34], an OSI difference > 0.5 between the groups was considered to represent a clinical difference. A power analysis was performed to determine the sample size, with an alpha level of 0.05 and a power of 0.8.…”

Background: The modified Broström procedure (MBP) is an initial treatment in symptomatic chronic ankle instability (CAI) patients. However, there was a deficiency of studies regarding the recovery of proprioception and neuromuscular control at the timing of a return to sports after MBP. This study aimed to compare the proprioception and neuromuscular control of both affected and unaffected ankles at the timing of a return to sports after MBP in CAI patients with those of normal controls. Methods: Totally, 75 patients (40 who underwent MBP vs. 35 normal controls) participated. Proprioception and neuromuscular control were measured by postural stability and time to peak torque, respectively. Postural stability tests included static and dynamic balance and the star excursion balance test (SEBT). Static and dynamic balance were tested using a postural stabilometry system, and time to peak torque was measured using an isokinetic device. Results: The dynamic balance test was significantly higher in the affected ankle of the MBP group than in controls (1.5 ± 0.6 vs. 1.1 ± 0.4, p < 0.003). SEBT was significantly lower in the affected ankle of the MBP group compared to controls (anterior: 70.9±16.4 vs. 80.3±11.7, p < 0.006; posterior: 49.2 ± 10.0 vs. 62.2 ± 19.0, p < 0.000; lateral: 49.9 ± 12.7 vs. 57.3 ± 17.7, p < 0.040). Time to peak torque was significantly increased in the affected ankle of the MBP group compared to controls (dorsiflexion: 608.3 ± 139.4 vs.522.9 ± 175.8, p < 0.022; eversion: 689.1 ± 191.6 vs. 593.1 ± 211.2, p < 0.043). Conclusion: Dynamic balance, SEBT, and time to peak torque in CAI patients remained significantly reduced at the timing of a return to sports after MBP.

“…The sample size calculation for the present study was based on a previous study of muscle strength in patients with lower extremity injuries, [19,22] and a muscle strength difference >10% between the groups was considered signi cant. To determine the sample size, we conducted a priori power analysis, with an alpha level of 0.05 and a power of 0.8.…”

Background: Muscle weakness has been reported to be an important etiological factor in plantar fasciitis (PF), but the data available in the quadriceps, hamstring, gastrocnemius (GCM) muscles is limited . The aim of the study was to compare the strength and reaction time of the quadriceps, hamstring, and gastrocnemius (GCM) muscles and foot pressure between patients with PF and normal controls. Methods: 21 PF patients and 21 normal controls were registered. Muscle strength was measured by the peak torque per body weight (Nm kg−1 × 100). Muscle reaction time was evaluated by the acceleration time (AT, milliseconds). Foot pressure and posture were assessed by pedobarography [valgus/varus index (VV index), %].Results: The strength of the quadriceps was significantly decreased in the affected ankles of the PF group than in the control group (p=0.005). The AT of the quadriceps and hamstring muscles was significantly increased in the affected ankles of the PF group than in the control group (quadriceps: p=0.012, hamstring: p=0.001), while the AT of the GCM muscle was significantly decreased (p=0.009) and was significantly negatively correlated with quadriceps muscle strength (r=-.598, p = .004) and AT (r=-.472, p=.031). Forefoot (p=0.001) and hindfoot (p=0.000) pressure were significantly greater, with the VV index showing hindfoot valgus, in the affected ankles of the PF group when compared to those of the control group (p=0.039).Conclusion: This study demonstrated weakness and delayed reaction time of the quadriceps and hamstring muscles, with a rapid reaction time of the GCM muscle, in PF patients. Clinical Relevance: Clinicians and therapists should assess the function of the quadriceps and hamstring muscles when planning the management of PF patients without muscle tightness.
