The Effect of Low-Intensity Blood Flow Restriction Therapy on the Management of Acute Ankle Sprains
Purpose
The primary objective of this study is to evaluate the feasibility of implementing BFR in the rehabilitation treatment of isolated ankle sprains as well as to evaluate the clinical benefits of BFR when compared to standard treatment. This study will evaluate the efficacy of using BFR therapy for the treatment of acute grade I and II ankle sprains. The investigators will evaluate clinical outcomes of range of motion (ROM) and strength testing of ankle dorsiflexion, plantarflexion, inversion, and eversion. This will be a small, randomized control trial study. The investigators will enroll a total of 40 participants, 20 participants will undergo standard physical therapy for isolated lateral ankle sprains and 20 participants will undergo BFR therapy for an isolated lateral ankle sprain. Patients will be randomized into control and experimental group via block randomization.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Blood Flow Restriction Group |
1. Patient specific tourniquet settings to achieve 80% occlusion. 2. Weight- 20% of 1 rep max, 4 sets 30-15-15-15 reps with 30 second rests between sets 3. Exercises: The first phase will focus on active and passive range of motion of the ankle as well as non-weighted concentric exercises. Phase two will progress with gastrocnemius and soleus stretches along with body weight and light resistance band concentric and eccentric exercises focusing on posterior, anterior and lateral muscle groups of the lower limb. Phase three will introduce weighted, dynamic and proprioceptive exercises. |

Active Comparator Non-Blood Flow Restriction Group |
This group will perform the same exercises for the same volume without the use of BFR. |
