Blood Flow Restriction and Proprioception Training on Ankle Joint Sensations

Официальное название

Effect of Adding Blood Flow Restriction and Proprioception Training to Traditional Rehabilitation on Ankle Joint Sensations

Обзор

Thirty-four participants with grade I and II recurrent ankle sprain, were referred from orthopaedic physician. Their ages ranged from 20 to 30 years old. All participants will be divided randomly into two groups A, B. Seventeen participants per group. Participant selected from both sexes, with body mass index between 18 and 24.9 Kg/m², with self-reported history of at least one significant lateral ankle sprain (LAS) greater than 12 months prior to testing and recurring ankle sprains, ankle "giving way" and/or "feelings of instability". Participants with previous surgery or fracture and with any adverse effects to blood occlusion will be excluded.

Вмешательства

• Другое conventional physical therapy
  consist of Strengthening exercise: will begin with isometric exercises performed against an immovable object in four directions of ankle movement (dorsiflexion, planter flexion, inversion, and eversion) and will be progressed to dynamic resistive exercises (isotonic exercises) using ankle weights. and Bracing: The participants will receive instructions from the therapist about using and applying the soft brace. The soft brace will be based on the principles of the functional tape bandage
• Другое Low load blood flow restriction
  Patients in blood flow restriction training groups will receive low load resistance exercise (20-40 % 1RM) using tourniquet around thigh proximally to knee joint to occlude arterial blood flow by 50-80 %.
• Другое proprioception training
  Patients will receive proprioception exercises in duration of 30 minutes per session, frequencies will be 3 times per week, and lengths for 4 weeks (Matthew et al., 2017). Progression of the proprioceptive training should be static to dynamic (such as lateral movements, backward movements, jumping, cutting, twisting, pivoting), slow speeds to faster speeds with balance and control, two legs to one leg, and with visual control to no visual control.

• limits of stability [Срок оценки: after three times weekly physiotherapy sessions for four consecutive weeks.]
