About

Chronic ankle instability (CAI) is an increasingly prevalent condition among futsal athletes. Mobilization with Movement (MWM) is a conservative rehabilitation strategy commonly used in this condition. Even so, the effects of two MWM dorsiflexion techniques on sports performance are not known. The aim is to analyze the immediate effect of two MWM techniques on the dorsiflexion range of motion, the dynamic balance and the performance variables in futsal athletes with CAI. Also, to analyze the impact of performing them in a different order.

Enrollment: 18 patients

Sex: Male

Ages: 18 to 35 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. A history of at least one significative ankle sprain:

   • Initial sprain must have occurred at least 12 months prior to study enrolment;
   • Was associated with inflammatory symptoms;
   • Created at least one interrupted day of desired physical activity;
   • The most recent injury must have occurred more than 3 months prior to study enrolment.

2. A history of the previously injured ankle joint "giving way" and/or recurrent sprain and/or "feelings of instability":

   • Participants should report at least two episodes of "giving way" in the 12 months prior to study enrolment, to account for the seasonal nature of futsal;
   • Recurrent sprain was defined as two or more sprains to the same ankle.

3. Self-reported ankle instability should be confirmed with the Ankle Instability Instrument: answer "yes" to at least 5 yes/no questions.

Exclusion criteria

1. A history of previous surgeries to the musculoskeletal structures (i.e., bones, joint structures, nerves) in either lower extremity.
2. A history of bilateral ankle sprain.
3. A history of a fracture in either lower extremity requiring realignment.
4. Acute injury to musculoskeletal structures of other joints of the lower extremity in the previous 3 months that impacted joint integrity and function (i.e., sprains, fractures), resulting in at least one interrupted day of desired physical activity.
5. Have conditions for which manual therapy is generally contraindicated (such as the presence of a tumour, fracture, rheumatoid arthritis, osteoporosis, prolonged history of steroid use, or severe vascular disease).
6. Receiving concurrent physiotherapy treatment in the last 3 months.
7. Inability to read Portuguese.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

18 participants in 4 patient groups, including a placebo group

Mobilisation with Movement 1 (MWM1)

Experimental group

Description:

Participants received two ankle dorsiflexion MWM techniques, with glides applied at fibula and talus. Three sets of 10 repetitions of each techniques, were administrated.

Treatment:

Procedure: Mobilisation With Movement 1

Mobilisation with Movement 2 (MWM2)

Experimental group

Description:

Participants received two ankle dorsiflexion MWM techniques, with glides applied at talus and fibula (order of application inverted). Three sets of 10 repetitions of each techniques, were administrated.

Treatment:

Procedure: Mobilisation With Movement 2

Placebo

Placebo Comparator group

Description:

The Placebo group participants performed the same number of sets and repetitions of lean/lunge forward into dorsiflexion, without any glide application, in the same position

Treatment:

Other: Placebo

Intervention

Experimental group

Description:

The experimental groups (MWM1 and MWM2), were later merged into a single Intervention group.

Treatment:

Procedure: Mobilisation With Movement 2

Procedure: Mobilisation With Movement 1
