Brief Summary

After an initial ankle sprain, Chronic Ankle Instability is one of the most common residual symptoms which include pain, swelling, recurrent sprain, episodes of ankle joint "giving away" or decreased function. Recently, Whole Body Vibration (WBV) training has been introduced as a preventive and rehabilitative tool. It can be hypothesized that WBV on unstable surfaces might enhance neuromuscular control. Therefore, the aim of this study was to investigate the effects of a 6-week WBV training on an unstable surface on body composition, balance, strength and reflex and muscle activity of ankle muscles in recreational athletes with CAI.

Outcome Measures

Primary Outcomes (4)

• Change in electromyographic activity

  Baseline: before the initiation of the exercise programs (at most 7 days before the initiation of the exercise programs). First follow-up measurement: after the completion of the exercise programs (at most 7 days after the completion of the last training session. Average time period: six weeks after the initiation of the intervention). Second follow-up measurement: 6 weeks after the completion of the exercise programs (average time period: twelve weeks after the initiation of the intervention)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

• Change in muscle strength

  Baseline: before the initiation of the exercise programs (at most 7 days before the initiation of the exercise programs). First follow-up measurement: after the completion of the exercise programs (at most 7 days after the completion of the last training session. Average time period: six weeks after the initiation of the intervention). Second follow-up measurement: 6 weeks after the completion of the exercise programs (average time period: twelve weeks after the initiation of the intervention)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

• Change in balance (Biodex Balance System test)

  Baseline: before the initiation of the exercise programs (at most 7 days before the initiation of the exercise programs). First follow-up measurement: after the completion of the exercise programs (at most 7 days after the completion of the last training session. Average time period: six weeks after the initiation of the intervention). Second follow-up measurement: 6 weeks after the completion of the exercise programs (average time period: twelve weeks after the initiation of the intervention)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

• Change in balance (Star Excursion Balance Test (SEBT)

  Baseline: before the initiation of the exercise programs (at most 7 days before the initiation of the exercise programs). First follow-up measurement: after the completion of the exercise programs (at most 7 days after the completion of the last training session. Average time period: six weeks after the initiation of the intervention). Second follow-up measurement: 6 weeks after the completion of the exercise programs (average time period: twelve weeks after the initiation of the intervention)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

Secondary Outcomes (2)

• Change in lean mass and fat mass (obtained using the enCORE software (GE Healthcare, v. 13.40)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

• Change in bone mineral content and bone mineral density (obtained using the enCORE software (GE Healthcare, v. 13.40)

  baseline, after the completion of the intervention, and 6 weeks after the completion of the intervention

Study Arms (3)

Control group

NO INTERVENTION

No intervention

Vibration group

EXPERIMENTAL

Proprioceptive training on a whole body vibration platform. Participants in the Vibration group trained with a BOSU® on a Fitvibe Excel Pro vibration platform (Fitvibe, Bilzen, Belgium).

Other: Proprioceptive training on a whole body vibration platform

Non-vibration group

EXPERIMENTAL

Other: Proprioceptive training with the BOSU® on the floor

Interventions

Proprioceptive training on a whole body vibration platform OTHER

The Training programme consisted of three series of 4 exercises of 45 seconds with 45 seconds rest between exercises. In this intervention participants trained with the BOSU® on a Fitvibe Excel Pro vibration platform (Fitvibe, Bilzen, Belgium).

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• History of at least 1 significant ankle sprain (the most recent injury must have occurred more than 3 months prior to study enrolment).
• or more episodes of the ankle giving way in the last 6 months.
• A score of ≤24 on the Spanish version of the Cumberland Ankle Instability Tool.

You may not qualify if:

• History of previous surgeries to the musculoskeletal structures in either lower extremity.
• History of a fracture in either lower extremity requiring realignment.
• An acute injury to musculoskeletal structures of other joints of the lower extremity in the previous 3 months that impacted joint integrity and function, resulting in at least 1 interrupted day of desired physical activity.
