(1) Background: VR is based on a virtual world that creates sounds effects and videos that replace the real environment. Arising literature shows VR efficacy in the field of neurological rehabilitation (NR) and that its use is also taking a place in musculoskeletal rehabilitation (MSR), as a treatment of various disorders that cause disability and chronic pain. (2) Aim: We discuss the role of VR in MSR, presenting its use and development on acute and chronic musculoskeletal disorders, based on the most recent literature. (3) Design and Methods: Literature searches were conducted in the databases Pubmed and Medline up to 30 September 2023. The PRISMA-Scr Checklist was followed. (4) Results: A total of 51 records were included. The analysed studies were conducted within a variety of populations, musculoskeletal disorders, settings, and VR technologies. Only a few studies could statistically affirm the efficacy of VR in MSR, as mentioned for the rehabilitation of the upper limb. Nevertheless, the observed trend is an improvement of the global perceived effect compared to traditional rehabilitation. (5) Conclusion: VR allows for the personalisation of treatment with an adaptable treatment platform, which may improve the participation of the patient and increase acceptability and adherence to long-term rehabilitation programs. We provide recommendations and suggestions for future research and use of VR in musculoskeletal rehabilitation.

The PLUS-M 12-item Short-Form is a self-questionnaire that assesses the perceived capacity of lower limb amputees (LLAs) to perform a number of daily-life activities. Its psychometric properties are excellent (intraclass correlation coefficient [ICC]>0.9, fast administration and scoring, normative data available), and it can be used in clinical practice or for research purposes. We aimed to develop a French version of this questionnaire and to assess its psychometric properties. We followed international recommendations for translation and cross-cultural validation of questionnaires. In total, 52 LLAs (age 53±16, 40 males, 28/12/12 transtibial/Gritti-Stokes/transfemoral, 20/28/4 ischemic/traumatic/other) participated. Criterion and construct validities were assessed with the Pearson correlation coefficient (PCC) between the PLUS-M 12-item Short-Form and other constructs (Prosthetic-Profile-of-the-Amputee-Locomotor Capabilities Index, Activities-specific Balance Confidence scale, 2-min walking test and Timed Up and Go test), internal consistency with the Cronbach α and reliability with the ICC in 46 individuals who completed the questionnaire twice in a 7-day interval. The mean (SD) PLUS-M 12-item Short-Form T-score was 56.1 (7.8; range 40.3 to 71.4). Construct and criterion validity, internal consistency and reliability ranged from low to excellent (r=0.43 to 0.84, P<10-2 to 0.002; Cronbach α=0.90, ICC=0.89 [0.81-0.94]). We found no floor or ceiling effect. The French version of the PLUS-M 12-item Short-Form has good to excellent psychometric properties, comparable to those of the original version. Its use could definitely be proposed for both clinical and research purposes, once its validation is completed by assessing other psychometric qualities, especially sensitivity to change.

We present the unusual case of complex regional pain syndrome (CRPS) of the residual limb in a 54-year-old woman with transtibial lower-limb amputation. Intractable pain developed 14 months after amputation, followed by successful rehabilitation. Anamnesis and clinical findings included sensory symptoms, vasomotor symptoms and signs, and oedema. The Budapest criteria for a diagnosis of CRPS were met. After infusions of bisphosphonates during a 5-week inpatient interdisciplinary rehabilitation programme, the pain decreased. Clinicians should suspect CRPS in case of chronic or recurrent residual limb pain. The Budapest criteria seem applicable even if interpretation of symptoms and findings can be complicated in vascular polymorbid lower-limb amputation. Bisphosphonates, proposed as first-line pharmacological treatment, can be useful.

An 11-year-old previously healthy and vaccinated female presented to our centre with a 2-day history of left foot edema associated with tenderness, erythema, and inability to bear weight on the affected foot. She had no fever. She was seen in an outpatient clinic 2 days prior to her presentation and started on oral cephalexin; however, her symptoms worsened and erythema had ascended rapidly. On examination, she was clinically well and afebrile. Puncture wound was present between her left fourth and fifth toe with a large amount of white watery discharge coming through the wound. She had significant pitting edema and erythema of her left foot extending up to left distal tibia with warmth, tenderness, and normal ankle joint range of motion ( Figure 1). Her initial blood work showed a white blood cell count of 12.4 × 109/L, with an absolute neutrophil count of 7.6 ×...
