1 Introduction

The following are the most common causes of ankle injuries: improper landing when jumping off high objects, landing on uneven surfaces, falling. One more factor of endurance decrease of ankle ligaments and synovial capsule of the ankle joint is age. On the other hand, high level of physical activity also contributes to the risk of ankle joint injuries. Traumas of ankle ligaments are the most common injuries among athletes [2, 3, 4].

Physical rehabilitation is the leading method of the ankle joint recovery. Early and comprehensive rehabilitation is the most advanced method of the injured ankle joint motor functions recovery. Comprehensive rehabilitation widely uses methods of physical rehabilitation – therapeutic physical exercises, hydrotherapy, massage, physiotherapeutic procedures [5, 7].

Based on the outlined goal, the following tasks were identified:

  1. Study the problem of the research, based on literature sources;

  2. Develop exercises for rehabilitation of ankle joint traumas;

  3. Validate the efficiency of the developed rehabilitation method.

2 Materials and Methods

The experiment in development of a set of exercises of adaptive physical training aimed at rehabilitation of ankle joint traumas was held at the State Municipal Institution of Nizhniy Novgorod Region “Exercise Therapy Centre” (8A Krasnykh Partizan Str., Nizhniy Novgorod, Russia).

10 children aged 12 to 14 years took part in the experiment. All children had injuries of ankle joints and at the time were in the third period of recovery (see Chart 2). To validate the experiment, two groups were formed: experimental (10 people) and reference (10 people). The development of the set of exercises aimed at rehabilitation of ankle joint traumas was carried out throughout the whole period of exercising. Later on, a second round of research was held in the same conditions to assess the results.

During the first stage of the research it was found out, that physical rehabilitation is a logical continuation of any kind of treatment: surgical, pharmaceutical, physiotherapeutic, and is aimed at recovery of qualitative capabilities of the ankle joint.

The rehabilitation program is a certain sequence of actions. They have to be made to restore the lost motor functions. The main tool of rehabilitation is exercising. The exercises need to be selected correctly with account for the specifics of the injury, properly organized through the use of technical means, fixtures, special rehabilitation equipment, and correctly performed [1, 11, 14, 15].

3 Results and Discussion

The following tests were performed during the experiment [9, 12, 13]:

  1. Assessment of the general physical condition of 12 to 14 years of age children with ankle injuries before and after rehabilitation;

  2. Assessment of the injured joint motion range with goniometer;

  3. Assessment of walking characteristics of children with an injured ankle before and after rehabilitation;

  4. Bondarevsky test to assess balancing ability before and after rehabilitation.

After completion of the rehabilitation, statistically significant positive shifts occurred in functional conditions of 12 to 14 years of age children ankle joints that took part in the research (Table 1).

According to the results of the research, we were able to determine shin circumference before and after the experiment in the research group. Before the experiment, the shin circumference was on average 31.5 cm, after application of the developed method – 32.1 cm. It indicates a change in the result by 0.6 cm (with p < 0.001).

After application of therapeutic physical training set of exercises, the results of walking goniometry of 12 to 14 years of age children have also improved: the bending angle changed by 5.3°, and angle of extension changed by 2.7°. The bending angle was 41.9°, and the angle of extension was 19.3° (with p < 0.001). At the beginning of the experiment the average bending angle of the ankle joint was 36.6°, and average angle of extension was 16.6°.

It is worth noting that functional state of the joints and main characteristics of the group walking under examination improved after the rehabilitation methods had been implemented.

The length of step of children from the experimental group has improved on average by 0.7 m and was equal to 52.2 m. At the beginning of the experiment the children walked with the speed of 3.66 km/h, and at the end of the experiment the walking speed was 4.65 km/h (with p < 0.001). The muscular strength of lower limbs, namely of the ankle joint, improved, and muscular tone recovered.

The rehabilitation program for ankle injuries for children of 12 to 14 years of age is intended for 30 days and includes sets of physical exercises, combined with electrophoresis, magnet therapy, and massage. Massage was performed daily.

During each session, the state of a child health was closely monitored. At significant levels of pain, the exercises were performed at slow pace, and with severe levels of pain the exercises were performed at the pace most comfortable for the child. In proportion to pain relief, the exercises were performed at a more rhythmical moderate pace: each exercise was performed 10 to 15 times; the most painful move was performed 5 to 7 times.

The movement amplitude was carefully selected not to cause pain increase. The amplitude was gradually increased, and all the movements were performed until the “pain point” was reached. All exercises were performed freely, smoothly, without any effort or abrupt movements. All of the movements were firstly performed with the healthy limb, and only then with the injured one.

During sessions the correct interchange of exercises was accounted for. If the pain levels increased during an exercise, the patient stopped the performance of this exercises and tried again after several sessions when the pain levels dropped.

A set of exercises aimed at training of muscular strength and resistance to static and dynamic loads with the use of isometric exercises and active exercises or resistance exercises (with the use of rubber band, expander), and exercises aimed at recovery of kinesthetic sense [6, 8, 10] were used as remedial gymnastics. Such exercises were performed daily.

See Table 2 below for the list of exercises that were performed at this stage of rehabilitation.

In one week a second set of exercises was implemented to train balance. It included proprioceptive exercises with the use of a balancing disk (Table 2).

The set was performed by the children 2 times per day for 30 minutes: first time at the gym, second time – at home.

4 Conclusions

The rehabilitation program is intended for 30 days and includes sets of physical exercises combined with electrophoresis, magnet therapy and massage. A set of exercises aimed at training of muscular strength and resistance to static and dynamic loads with the use of isometric exercises and active exercises or resistance exercises (with the use of rubber band, expander), and exercises aimed at recovery of kinesthetic sense were used as remedial gymnastics. A set of exercises aimed at training of balance, which included proprioceptive exercises with the use of a balancing disk was also implemented. During the course of solving the third task, the efficiency of the developed rehabilitation method was assessed by means of testing.

The research has shown that the rehabilitation of the ankle joint is one of the most important factors of restoring motor activity by way of using the means and methods of physical training with adequate loads, combined with other means of comprehensive rehabilitation methods aimed at improvement of the recovery process efficiency after ankle joint injuries.
