About this study
Official title: Effect of Adding Blood Flow Restriction and Proprioception Training to Traditional Rehabilitation on Ankle Joint Sensations
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.
- Conditions
- Lateral Ankle Sprain
- Being tested
- conventional physical therapy, Low load blood flow restriction, proprioception training
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
conventional physical therapyOther
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
Low load blood flow restrictionOther
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 %.
proprioception trainingOther
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.

| Group (B) | Experimental | Experimental Group B received conventional physical therapy with Low load blood flow restriction Receives: Other: conventional physical therapy; Other: Low load blood flow restriction |
| Group (C) | Experimental | received conventional physical therapy with proprioception training Receives: Other: conventional physical therapy; Other: proprioception training |

What is being measured
The primary outcome is the main question the study is designed to answer.
peak torque of ankle muscles
Each participant will be seated on the dynamometer chair in a relaxed position with the hip joint slightly flexed and the knee flexed about 45° so that the fulcrum of the dynamometer will be corresponded to the axis of the participant's ankle joint with the foot resting on the ankle attachment in a neutral position between dorsi flexion and planter flexion; standard toe straps will be used over the foot. Also, two straps will be wrapped around theextremity proximal to the patella and the pelvis to minimize movements of the trunk, hip, and knee during testing, which would interfere with the ankle measurement
Measured: after three times weekly physiotherapy sessions for four consecutive weeks.
limits of stability
Before the start of each testing session, the Biodex will be calibrated according to the manufacturer's manual. The participants will be familiarized with testing procedures through free practical sessions to minimize the learning effects that occur during testing. All measurements will be performed at level eight of stability (the most suitable level), and the test duration will be set at 20 seconds for three successive trials. Each participant will be tested for stability index (SI) and limits of stability (LOS). The limits of stability (LOS) are defined as the area that the subject safely moves without changing the base of support. The stability index (SI) represents the patient's ability to control balance and motor control skills at 50% LOS
Measured: after three times weekly physiotherapy sessions for four consecutive weeks.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
