Detailed Description

Haemophilia is an X-linked hereditary sex recessive disorder that impairs the body's ability to make blood clots. It includes two types: A (FVIII deficit factor) and B (IX deficit factor), depending on FVIII/FIX percentage in blood. The severity of haemophilia is classified into (severe: <1%, moderate: 1-5%, and mild: >5%). The prevalence of haemophilia A is 1: 5000 live births and haemophilia B is 1: 30000 live births.

This disease is characterized by hemarthrosis which is a hemorrhage in the locomotor system, mainly muscles and joints. Joint bleeding mainly occurs in knees, ankles and elbows. Haemorrhage in the muscle or joints accounts for 80% to 90% of all bleeding episodes in people with haemophilia. The most commonly affected joints in non-prophylaxis patients are the knees (45%) which is thought to be due to the large size of the synovial membrane and large rotational forces present. It is followed by the elbows (30%), ankles (15%), shoulders (3%), and wrists (2%). Bleeds are best detected by the patients themselves as bruising and swelling or described as a feeling of warmth or tingling within the joint preceding the clinical signs.

Pulsed electromagnetic field (PEMF) has been reported to be effective in reducing pain, healing of ulcers and promote bone healing, and treating osteoarthritis and inflammatory diseases of the musculoskeletal system. Also, it was reported that PEMF exposure significantly increases the anti-inflammatory effect, suggesting its potential therapeutic use in the treatment of inflammatory bone and joint disorders.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 16 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

EXPERIMENTAL: Placebo group
Other: PEMF
group A received 60 minutes of traditional program physical therapy which consisted of passive range of motion, stretching,proprioception, isotonic and isometric and 20 minutes of placebo treatment using PEMF, while group B received the same traditional physical therapy program given to the control group in addition of 20 minutes of PEMF therapy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
swelling
Time Frame: basline and after 3 months of intervention.
The swelling degree was detected by tape
basline and after 3 months of intervention.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
range of motion
Time Frame: basline and after 3 months of intervention.
Active knee range of flexion and extension were measured by electronic goniometer.
basline and after 3 months of intervention.
muscle strength
Time Frame: basline and after 3 months of intervention.
The peak concentric knee extensor (KE) and the peak concentric knee flexor (KF) was measured at 60/s angular speed by an isokinetic dynamometer.
basline and after 3 months of intervention.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
