Attentional Focus in Single-Leg Squat for Ankle Sprain

NCT07106476 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 32

Last updated 2025-08-06

No results posted yet for this study

Summary

This study investigates the acute effects of single-leg squat exercises conducted under different attentional focus strategies (internal, external, and no focus) on plantar pressure distribution and posterior chain muscle activation in individuals with a history of unilateral ankle sprain. The study aims to determine whether external focus improves neuromuscular efficiency and postural control compared to internal or no attentional focus.

Conditions

  • Unilateral Ankle Sprain
  • Chronic Ankle Instability
  • Muscle Activation
  • Postural Control
  • Attentional Focus in Exercise
  • Neuromuscular Function

Interventions

OTHER

Single-Leg Squat with Internal Focus Intervention

Administration: Participants were instructed to focus on specific muscular or joint movements during single-leg squats (3 sets of 8 repetitions on the affected side, 1-minute rest between sets). Verbal cues included "contract your glutes" or "keep your knee aligned." Data Collected: Surface EMG (Gluteus Medius, Biceps Femoris, Lateral Gastrocnemius, Peroneus) and pedobarographic parameters.

OTHER

External Focus Intervention

Administration: Participants were instructed to focus on the environmental effects of single-leg squats (3 sets of 8 repetitions on the affected side, 1-minute rest between sets). Verbal cues included "push against the floor" or "drive your foot downward." Data Collected: Surface EMG (Gluteus Medius, Biceps Femoris, Lateral Gastrocnemius, Peroneus) and pedobarographic parameters.

OTHER

No Focus Intervention

Administration: Participants performed single-leg squats naturally without specific attentional instructions (3 sets of 8 repetitions on the affected side, 1-minute rest between sets). Data Collected: Surface EMG (Gluteus Medius, Biceps Femoris, Lateral Gastrocnemius, Peroneus) and pedobarographic parameters.
