What is the Effect of Low-load Blood Flow Restriction Training in the Nonoperative Rehabilitation of Ulnar-sided Wrist Pain?

Patients presenting to the hand therapy or hand surgery clinic who meet inclusion criteria will be screened, consented, and enrolled. This will include administration of the blood flow restriction screening questionnaire.

Patients with non operatively managed ulnar-sided wrist pain, who have been immobilized for at least 4 weeks 0 days, but no more than 6 weeks 6 days, and are referred to Stanford's Hand Therapy clinic, will receive either standard care or a standard care home program with low-load strengthening under a blood flow restricted (BFR) condition during their therapy sessions. Patients will be assigned to groups in simultaneous enrollment in two arms. The control group will receive standard rehabilitation during therapy visits plus a home program that will be dictated based on the associated phase of rehabilitation. The treatment group will receive standard rehabilitation as a home program plus low-load resistance training with BFR application while at the hand therapy clinic for their appointments, both of which will be dictated based on the associated phase of rehabilitation. Therapists will use the OMNI-Resistance Exercise Scale for Rate of Perceived Exertion Active Muscles (OMNI-RES RPE-AM) to grade all strengthening exercises for each individual in both groups. The target RPE-AM for each exercise will be 7-9 by the last set for resistance exercises in both control and treatment groups.
