Manual Therapy in Haemophilic Arthropathy of the Knee

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the effectiveness of two Physiotherapy treatments: one with manual therapy using joint traction, passive muscle stretching, and isometric exercise, active resisted and proprioception exercises; and other treatment with educational sessions and home exercises to improve the ROM, muscle strength and proprioception in patients with haemophilia and arthropathy of the knee.

Detailed Description
-----------------
Randomized trial with two treatment groups: one using joint traction, passive muscle stretching and isometric exercises, active resisted and proprioception exercises (group MT); and another with educational sessions and home exercises (group E); and a control group (group C). The intervention was carried out during twelve weeks, performing evaluation before and after treatment, and six months of finalizing this. The treatment in MT group consisted of two sessions per week for one hour each, and the treatment in group E consisted of a session of 90 minute every two weeks, with exercises daily home. The control group (group C) did not receive any treatment. After the allocation to the groups, the composition was follows: MT group = 7; E group = 7; and control group = 7.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Manual Therapy group<br>We employed joint traction, passive muscle stretching and isometric exercises, active resisted and proprioception exercises. The treatment in this group consisted of two sessions per week for one hour each. | Other: Manual Therapy<br>* 5 minutes. Thermotherapy shallow to 50 cm away from the knee. 15 minutes. Joint traction, grade I-II. Fixation of distal femur with cinch and manual fixation of proximal tibia. Patient in prone position and the traction is carried out in the submaximal ranges of flexion and extension. 10 minutes. Passive muscle stretching of quadriceps (within the limits of mobility), through compression muscle, passive muscle stretching and relaxation of muscle. 10 minutes. Isometric and resisted exercises of quadriceps, in submaximal ranges, of flexion and extension. 10 minutes. Proprioception exercises with unipodal support, with and without visual support, and posterior destabilization. 10 minutes. Local cryotherapy with ice pack.<br>|
| Experimental: Educational gruop<br>This group received educational sessions and home exercises. The exercises are aimed at improving quadriceps strength, flexibility, range of motion and knee proprioception. Each educational session of 90 minute every two weeks, with exercises daily home | Other: Educational Physiotherapy<br>* Theory. Introduction to hemophilia: clinic and treatment; Anatomy and biomechanics of knee; Anatomy of ankle musculature; Function of muscles and haematomas treatment; Haemarthrosis, synovitis and arthropathy: clinical manifestations; Proprioception: definition and importance in hemophilia; and Physical activity and sport: risks and benefits. Practice: exercises in favor of gravity; active exercises for mobility and pain management; knee proprioception exercises; isometric and isotonic exercises of quadriceps; swimming and cycling technique.<br>|
| No Intervention: Control group<br>The control group (group C) did not receive any treatment. The patients of this group were assessed by the same reviewers and under the same conditions as the subjects of the two intervention groups. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in the range of movement (ROM) | Measurement of knee flexion and extension using a universal goniometer. Were taken as anatomical references, are indicated by Querol et al, using the reference method 0 to the mobile arm of the goniometer, as noted Norkin et al. | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) | 
| Changes in quadriceps muscle circumference | Measurement in the thigh, in two thirds of the flow distance between the anterior superior iliac spine and the joint line of the knee, using a tape measure | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) | 
| Changes in muscle strength of quadriceps | Measured by the rupture test for hemophilia patients (with a gradation of 0 to 5 points, with 0 indicating normal strength and 5 is the absence of muscle contraction). | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) | 
| Changes in the perception of pain | Using the visual analog scale, VAS, consisting of a gradation of 0 to 10 points (from no pain to worst pain imaginable). | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) | 
| Changes in the assessment of radiological joint deterioration | We use the Petterson scale which consists of 13 items (0 indicates a normal joint and joint deterioration 13 maximum). | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subjects' physical characteristics | Age of patient (years), Weight of patient (kg), Number of ankle haemarthrosis in previous year, Type of haemophilia (A or B), Severity of haemophilia (severe or moderate), Treatment (prophylaxis or on demand). | Screening visit (pretreatment assessment) | 
| Changes in the frequency of knee hemarthrosis | Evaluation of knee bleeding before, during and after physiotherapy treatment. Hemarthrosis must be diagnosed clinically. | Screening visit (pretreatment assessment), postreatment evaluation (12 week) and follow up assessment (6 months after treatment) |
