Article Synopsis
  • The study investigates how hemophilic arthropathy affects balance, stability, and ankle functionality in patients compared to healthy individuals.
  • Significant differences were found in balance, ankle range of motion, and muscle strength, indicating that those with hemophilic arthropathy faced greater challenges in these areas.
  • Ultimately, the findings suggest that patients with this condition have worse ankle flexibility, balance, and strength than healthy peers.

(1) Background: Hemophilia is a bleeding disorder characterized by hemarthrosis. Prophylaxis is the gold standard for bleeding prevention. Extended half-life (EHL) recombinant FVIII replacement products have shown to be associated with low bleeding rates.

Background: Hemophilia is a congenital coagulopathy characterized by degenerative joint damage. Self-induced myofascial therapy aims to decrease pain and improve tissue mobility, functionality and proprioception.

Aim: The aim of this study was to evaluate the safety and efficacy of self-induced myofascial release in patients with hemophilic knee arthropathy.

(1) Background: Hemophilia is characterized by recurrent hemarthrosis leading to degenerative arthropathy. The aim was to evaluate the differences in muscle strength and activity and the pressure pain threshold between patients with knee arthropathy and their healthy peers; (2) Methods: A case-control study in which 23 adult patients with knee arthropathy and 24 healthy peers matched in terms of characteristics were recruited. The study variables were quadriceps muscle strength, muscle activation and the pressure pain threshold; (3) Results: There were significant differences between the two groups in quadriceps strength on the dominant (CI95%: 64.

Background: The hamstring muscles have a great tendency to decrease their extensibility, a phenomenon that presents a distinct clinical entity called short hamstring syndrome (SHS), in addition to problems with adjacent structures.

Objective: The objective of this study was to evaluate the immediate effect of lumbar fascia stretching on the flexibility of the hamstring musculature.

Methods: A randomized controlled trial was carried out.

Background: Hemophilic ankle arthropathy is manifested by degenerative functional alterations (reduced muscle strength, mobility, and proprioception) and chronic pain. Myofascial release techniques are used to treat soft tissue adhesions, relieve pain, and reduce tissue sensitivity. The aim was to evaluate the safety of self-induced myofascial release in patients with hemophilic ankle arthropathy and to assess possible changes in musculoskeletal variables.

(1) Background: Hemarthrosis is a typical clinical manifestation in patients with hemophilia. Its recurrence causes hemophilic arthropathy, characterized by chronic joint pain. Watching movement recorded from a first-person perspective and immersively can be effective in the management of chronic pain.

Hemophilia is a congenital coagulopathy characterized by a deficiency of one of the clotting factors. It is characterized by the development of hematomas and hemarthrosis, either spontaneously or after minor trauma. The recurrence of hemarthroses leads to progressive and degenerative joint damage from childhood (hemophilic arthropathy).

Background: Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management.

Aim: To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy.

Background: Prophylactic treatment is the gold standard in the treatment of patients with haemophilia. Prophylaxis with extended half-life (EHL) treatment has shown long-term safety and efficacy in patients with haemophilia.

Aim: To evaluate the efficacy of prophylaxis with EHL treatment in the frequency of haemarthrosis and musculoskeletal health in adult patients with severe haemophilia A.

Article Synopsis
  • The study assessed how fascial therapy impacts quality of life, pain, and joint health in hemophilia patients.
  • Participants (N=69) received either fascial therapy or no treatment at all, with sessions lasting 45 minutes once a week for three weeks.
  • Results showed significant improvements in physical and mental health, pain intensity, and joint health for those receiving fascial therapy compared to the control group.

Article Synopsis
  • Hemophilic knee arthropathy causes muscle loss and strength reduction in the quadriceps, and the study aimed to see if VR visualization of knee movements could enhance muscle activation in affected areas.
  • Thirteen patients with severe hemophilia A participated in a 15-minute immersive VR session, but results showed no significant changes in activation of the vastus medialis, vastus lateralis, or rectus femoris after the intervention.
  • Although the VR session did not improve overall muscle activation, there was a notable effect on rectus femoris activity, suggesting a need for tailored VR protocols to better target muscle activation in this specific patient group.

Article Synopsis
  • The study aimed to assess the impact of manual therapy on reducing hemarthrosis frequency, enhancing elbow range of motion, and improving disability perception in patients with hemophilia affecting the elbow.
  • The research involved 69 patients split into two groups, with the experimental group receiving weekly manual therapy sessions focused on upper limb fascial therapy for three weeks, while the control group did not.
  • Results indicated that manual therapy effectively decreased hemarthrosis frequency and improved elbow motion, but overall perceived disability showed no significant change; manual therapy proved safe and beneficial for these patients.

Article Synopsis
  • Hemophilic ankle arthropathy causes chronic pain and functional decline, and myofascial release techniques aim to alleviate these issues through soft tissue treatment.
  • This study investigates the safety and effectiveness of self-myofascial release using a foam roller in patients with ankle arthropathy, enrolling 70 participants divided into experimental and control groups.
  • Outcomes will be assessed through various measures, including ankle joint bleeding frequency, range of motion, pain levels, joint health, and muscle strength, with a treatment duration of 3 months involving 15-minute sessions five times a week.
