Ankle Isometric Strength and Proprioception in Young Ice Hockey Players (ANKLE-ICE)

December 30, 2025 updated by: Emine Merve Ersever

Comparison of Ankle Isometric Strength and Proprioception Between 9-10-Year-Old Junior Ice Hockey Players and Age-Matched Controls

This observational cross-sectional study aims to profile ankle isometric strength and proprioception in 9-10-year-old junior ice hockey players and to compare these outcomes and limb symmetry indices with age-matched non-athlete children. Ankle isometric muscle strength is assessed using a handheld dynamometer, and ankle proprioception is evaluated using a digital inclinometer. Measurements are performed bilaterally for dominant and non-dominant limbs. Group comparisons and limb symmetry analyses are conducted to identify potential neuromuscular differences related to sports participation.

Study Population

The study includes 70 healthy children aged 9-10 years, comprising junior ice hockey players and age-matched non-athlete controls.

Description

Inclusion Criteria:

  • Children aged 9 to 10 years.
  • For the ice hockey group: regular participation in organized junior ice hockey training.
  • For the control group: no participation in organized sports or structured athletic training.
  • Ability to understand and follow test instructions.
  • Written informed consent obtained from parents or legal guardians

Exclusion Criteria:

  • History of lower extremity injury within the past 6 months.
  • Previous ankle or lower limb surgery.
  • Presence of neurological, musculoskeletal, or balance disorders that could affect ankle strength or proprioception.
  • Current pain or injury affecting lower extremity function.
  • Any medical condition that would limit safe participation in the assessments.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ankle Isometric Strength
Time Frame: Single assessment session
Ankle isometric muscle strength of the dominant and non-dominant limbs measured using a hand-held dynamometer (Lafayette Manual Muscle Testing System). Peak force values are recorded for dorsiflexion, plantar flexion, inversion, and eversion.
Single assessment session

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ankle Proprioception
Time Frame: Single assessment session
Ankle joint proprioception assessed bilaterally for the dominant and non-dominant limbs using a joint position sense test with a digital inclinometer. Proprioceptive accuracy is expressed as absolute error in degrees between the target and reproduced ankle joint position.
Single assessment session
