Purpose: Up to 74% of breast cancer survivors (BCS) treated with aromatase inhibitor (AI) experience AI-induced musculoskeletal symptoms (AIMSS). AIMSS is the predominant cause of poor adherence to AI therapy, yet no definitive treatment exists. The primary research objectives of this study were (1) to develop a novel BCS-specific complex intervention to alleviate AIMSS, and to assess its feasibility.

Excessive muscle co-contraction is one of the factors related to the progression of knee osteoarthritis (OA). A previous study demonstrated that pain, joint instability, lateral thrust, weight, and lower extremity alignment were listed as factors affecting excessive co-contraction in knee OA. However, this study aimed to assess the association between fear-avoidance beliefs and muscle co-contraction during gait and stair climbing in people with knee OA.

Introduction: Aromatase inhibitor (AI)-induced musculoskeletal symptoms (AIMSS) can decrease health-related quality of life and lead to discontinuation of AI therapy for postmenopausal women with breast cancer (BC). Although central sensitization (CS) may contribute to AIMSS, the relevance of CS-related symptoms to AIMSS has not been fully clarified. This study aimed to investigate the relationship between AIMSS and CS-related symptoms in women with BC who received AI therapy.

Objective: As management for osteoarthritis, clinical practice guidelines (CPGs) have been published worldwide with the aim of attaining optimal treatment and rehabilitation. However, we suspect a lack of knowledge of and/or adherence to osteoarthritis CPGs in physiotherapists' clinical practice. There may be an evidence-to-practice gap in knee osteoarthritis rehabilitation among Japanese physiotherapists.

Although the prevalence of cancer pain is 47% after treatment, cancer pain is often underestimated, and many patients are undertreated. The complexity of cancer pain contributes to the lack of its management. Recently, as the mechanism of cancer pain, it has become clear that central sensitization (CS) influences chronic pain conditions and the transition from acute to chronic pain.

Article Synopsis
  • - The study evaluated how varus thrust (VT) during walking, measured with an inertial measurement unit, relates to patient-reported outcomes in individuals with knee osteoarthritis.
  • - Seventy participants walked on a treadmill while their VT was measured, and their knee pain and daily activity scores were assessed using a standard questionnaire.
  • - The analysis showed that higher VT values correlated with worse scores on pain, symptoms, and daily living activities, indicating that reducing VT could help improve these patient outcomes.

Article Synopsis
  • Pain after cancer is often overlooked and not adequately treated, leading to ongoing suffering for many patients.
  • Precision medicine aims to categorize patients based on their specific pain types—nociceptive, neuropathic, or nociplastic—to provide customized treatment plans.
  • The Cancer Pain Phenotyping (CANPPHE) Network has developed a systematic approach using the 2021 IASP criteria to help clinicians accurately identify and manage post-cancer pain, enhancing patient care through better diagnosis and treatment.

Background: Persistent post-surgical pain (PPSP) is associated with upper limb dysfunction and decreased quality of life and causes long-term suffering for breast cancer survivors after surgery. However, the predictors of PPSP remain unclear. The purpose of this study was to examine predictors of PPSP intensity and interference at 1 year postoperatively, focusing on treatment-related factors, pre- and postoperative central sensitization (CS), CS-related symptoms (e.

Introduction: Kinematic data obtained during a movement task by individuals with chronic low back pain seem to be related to pain-related fear. General kinesiophobia assessments, such as Tampa Scale for Kinesiophobia, are often used to assess pain-related fear. However, these questionnaires could suffer from a lack of sensitivity and do not measure the fear of specific movements.

We developed a novel quantitative method to assess varus thrust during walking using acceleration data obtained from an inertial measurement unit (IMU). This study aimed to examine the reliability of the developed index and to evaluate its ability to distinguish patients with knee osteoarthritis (OA) with varus thrust from healthy adults. Overall, 16 patients with knee OA and 16 healthy adults walked on a treadmill with IMUs attached to the tibial tuberosity and lateral femoral condyle.

Body re-sizing illusions can profoundly alter perception of our own body. We investigated whether creating the illusion of a muscled and fit-looking back (Strong) influenced perceived back size, body ownership, and attitudes towards self-capacity during a lifting task. Twenty-four healthy male volunteers performed a standardised lifting task while viewing real-time (delay < 20 ms) video of their own back through a head-mounted display under four different conditions (Normal size, Strong, Reshaped, Large; order randomised).
