Personalized Musculoskeletal Management: Navigating the Balance Between Clinical Reasoning and Non-Specific Effects.

Modern musculoskeletal (MSK) management has shifted towards a personalized, patient-centred approach, emphasizing individualized assessment, tailored exercise programs, education, and manual therapy (manipulations or mobilizations) (Lin et al., 2020). This approach advocates for interventions that consider the unique clinical presentation of each patient rather than relying on generic treatment protocols. The goal is to optimize patient outcomes by matching interventions to their specific pain mechanisms, functional limitations, and personal preferences. 

(Lin et al., 2018)

However, despite careful assessment and intervention planning, non-specific effects (e.g., contextual influences, clinician-patient interactions, and psychological factors) often blur the distinction between targeted and generalized benefits (Ezzatvar et al., 2024). This raises the question: How much of our tailored interventions are truly specific, and how much are driven by these non-specific factors?

(Ezzatvar et al., 2024)

This challenges the idea that clinical reasoning alone can precisely tailor interventions for each patient. Furthermore, the most commonly used musculoskeletal interventions, such as exercise and manual therapy, have shown only low to moderate effectiveness for several widespread conditions, including low back pain (Hayden et al., 2021; IJzelenberg et al., 2023), neck pain (Wilhelm et al., 2023), shoulder pain (Flowers et al., 2024; Shire et al., 2017) or knee/hip osteoarthritis (Sasaki et al., 2022). 

One possible reason for this low effectiveness could be the "one-size-fits-all" approach tested in most of clinical trials. If interventions are carefully matched to key clinical characteristics, such as pain profiles, their effectiveness may be more relevant (Cook et al., 2023; Smith et al., 2019). 

A promising approach to mitigate the influence of non-specific effects is to stratify patients and group them according to clinically relevant characteristics. Precision medicine is the ability to classify patients into subgroups that differ in their susceptibility to, biology of, or prognosis of a particular disease, or in their response to a specific treatment (Nijs et al., 2021). 

Furthermore, other contributing factors may play a role in defining precautions, prognosis, type of education and treatment choice such as:

CLINICAL REASONING FOR NOCICEPTIVE PAIN  

CLINICAL REASONING FOR NOCIPLASTIC PAIN

CLINICAL REASONING FOR NEUROPATHIC PAIN
