Not Applicable
Terminated
Conditions
Chronic Disease
Sprains
Joint Instability
Interventions
Other: Strength exercise
Other: Jumping exercise
Registration Number
NCT02115971
Lead Sponsor
Swanenburg
Brief Summary

The aim of this pilot study is to analyze the effect of a 12-week specific jump training compared with conventional therapy in patients with chronic functional instability of the ankle. It is to be evaluated to what extent the symptoms in of chronic functional instability of the ankle can be influenced in everyday life.

Detailed Description

There is a need for;

1. more homogeneous sub- groups with chronic functional instability of the ankle.

2. Studies are needed that older patients (up to 50 years) and also take into account women.

3. In addition, studies should be performed in a clinical environment and also at the same time clinically adapted test can be used as a form measurement.

Arm && Interventions
GroupInterventionDescription
Strength exerciseStrength exercisePhysical Therapy with a focus on stability and strength exercise. Strength exercise arm has also same duration of 12 weeks with comparable intensity. The program is according to a predetermined program. The 60-minute training is completed twice under supervision in the clinic's internal training group for outpatients.There is no contact with participants of other group. Between the two exercise sessions there is a training free day. The training process is documented by the training protocol. The incipient exercise intensity is considering personal performance. The intensity is increased after workout usual principles. The exercises are described with clear image and load parameters. The training exercises are regularly monitored.
Jumping exerciseJumping exercisePhysical therapy with a focus on specific jumping exercise. The jumping exercise will be performed for 12 weeks (3x/week), with a break of day between workouts. The 40-minute workout is completed 2 times under supervision in the clinic's internal training group for outpatients. 1 time they train on their own at home, based on a defined training program. The training process is documented by the training protocol. The incipient exercise intensity is taking personal performance into account. The exercise intensity is increased by a progressive scheme.
Primary Outcome Measures
NameTimeMethod
Change from Baseline in Gait variablesChange from Baseline in Gait variables at week 3, week 7, and at the end of therapy (week 12)

Gait variables will be assessed with the OptoGait system OptoGait system is a floor-based photocell system for measuring spatiotemporal gait parameters.

All measurements will be executed within 1hour

Secondary Outcome Measures
NameTimeMethod
Health questionnaireBaseline, week 3, week 7, and at the end of therapy (week 12), followup 12 months

EQ-5D is a standardised instrument for use as a measure of health outcome.

Foot function questionnaireBaseline, week 3, week 7, and at the end of therapy (week 12)

The Foot and Ankle Ability Measure (FAAM) is a self-report outcome instrument developed to assess physical function for individuals with foot and ankle related impairments.

BalanceBaseline, week 3, week 7, and at the end of therapy (week 12)

Time to Stability (Forceplate Accusway AMTI)

* 1 leg jump test

* step down test

Personal calendar12 months

Participant could enter any new ankle sprain into this calendar. As soon as possible after new ankle sprain the participant had to fill in the date, its cause, and sprain-related injuries. The calendar pages contained questions about the circumstances surrounding the new ankle sprain, including how and where it happened, activity performed, possible injury symptoms, time to recover and whether medical assistance or physical therapy was needed. Participants are also requested to record direct medical costs (e.g. physiotherapy, visits to general practitioners and medical specialists, nursing care, and medication) and indirect cost (e.g. disability related loss) using the "personal calendar". At the end of 2 month, a calendar page was sent by each patient to the investigators
