Blood Flow Restriction Training in Nonspecific Shoulder Pain: Study Protocol of a Crossover Randomised Controlled Trial.

"Nonspecific shoulder pain" encompasses various non-traumatic musculoskeletal shoulder disorders, diverging from diagnostic terminologies that refer to precise tissue-oriented clinical diagnosis. Blood flow restriction (BFR) training, involving partial arterial inflow and complete venous outflow restriction, has exhibited acute hypoalgesic effects primarily in healthy populations by increasing their pain thresholds. This study aims to examine whether a single BFR session with low-load exercises can alleviate pain perception among nonspecific shoulder pain patients.

Comparing hip and knee focused exercises versus hip and knee focused exercises with the use of blood flow restriction training in adults with patellofemoral pain.

Background: Hip and knee strengthening exercises are implemented in rehabilitation of patellofemoral pain patients, but typically use high loads (70% of 1 repetition maximum). This may lead to increased patellofemoral joint stress. Low load training (20-30% of 1 repetition maximum) with blood flow restriction could allow for exercise strength benefits to proximal and distal muscles with reduced joint stress and by promoting hypoalgesia.

Greek cultural adaption and validation of the Kujala anterior knee pain scale in patients with patellofemoral pain syndrome.

Purpose: To cross-culturally adapt and validate the Greek version of the Kujala anterior knee pain scale (KAKPS).

Methods: The Greek KAKPS was translated from the original English version following standard forward and backward translation procedures. The survey was then conducted in clinical settings by a questionnaire comprising the Greek KAKPS and patellofemoral pain syndrome (PFPS) severity scale.
