Why Many Patients with Musculoskeletal Pain Don't Improve: Kinesiophobia, Incorrect Dosage, and Lack of Feedback
In daily clinical practice, it is common to encounter patients with musculoskeletal pain who, despite receiving treatment, do not show significant improvement.
These are common profiles:
- chronic lower back pain
- shoulder pain
- knee conditions
In many cases, the problem lies not in the lack of intervention, but in how that intervention is being approached.
More specifically, three factors are usually involved:
- the presence of kinesiophobia
- insufficient exposure to movement (low effective dose)
- the lack of feedback during the exercise
Understanding how these elements interact is key to improving outcomes in musculoskeletal rehabilitation.

The clinical problem: patients who do not progress
A common scenario in the clinic is as follows:
A patient who exercises and attends sessions but continues to experience pain, functional limitations, and little improvement.
If we analyze these cases in detail, common patterns tend to emerge:
- low actual workload
- few effective repetitions
- improper execution of the movement
- avoidance of certain gestures
This suggests that the problem is not a lack of treatment, but rather insufficient, nonspecific, or nonprogressive exposure to movement.
Error 1: An overly structural approach
In many contexts, there is still a focus on:
- imaging findings
- anatomical abnormalities
- structural assessment
However, in cases of persistent musculoskeletal pain, the correlation between structure and symptoms is limited.
This can lead to:
- long-term passive treatments
- unnecessary avoidance of movement
- low level of patient engagement
Error 2: Kinesiophobia not identified or addressed
Kinesiophobia—defined as the fear of movement due to the anticipation of pain or injury—is a key factor in many patients.
How it presents in the clinic
- avoidance of specific movements
- rigid or protective execution
- hypervigilance regarding pain
- low exercise tolerance
Clinical impact
Kinesiophobia directly influences:
- Lower exercise intensity
- Lower caseload
- Less variability in movement
As a result, the patient reduces their exposure to the stimulus needed to trigger adaptation.
Mistake 3: The patient does less work than necessary
One of the most significant—and least obvious—problems is insufficient exposure to therapeutic exercise.
In clinical practice, this means:
- few repetitions per session
- low labor intensity
- long breaks
- low-impact workouts
This has direct implications:
Many rehabilitation programs do not reach the minimum volume required to bring about changes in strength, motor control, or load tolerance.
In addition, factors such as pain, boredom, or a lack of motivation further reduce the amount of actual practice.
Mistake 4: Lack of feedback during the exercise
Feedback is a central component of motor learning, but in many clinical settings it is limited.
This creates several problems:
- The patient doesn’t know if they’re doing it correctly
- increases insecurity during the move
- compensatory patterns are reinforced
- reduces the quality of the exercise
In patients with kinesiophobia, this lack of feedback can exacerbate:
- fear
- avoidance
- load reduction
Why this limits motor learning
For a functional change to occur, the following is necessary:
- a sufficient number of repetitions
- variability in practice
- feedback on implementation
Without these elements, the neuromuscular system does not receive the necessary stimulus to adapt.
Without sufficient, high-quality practice, there can be no effective motor learning or sustained functional improvement.
What characterizes patients who do improve
In contrast, patients who respond well to treatment typically exhibit:
- gradual exposure to movement
- greater caseload
- higher quality of workmanship
- less avoidance
They don’t necessarily do “more complex” exercises; rather, they accumulate more effective and better-controlled practice.
How motion-based and virtual reality technologies address these issues
In recent years, clinical tools have been developed that integrate:
- motion capture
- interactive environments
- virtual reality (semi-immersive and immersive)
These solutions make it possible to address the described deficits directly.
Real-time motion capture
Systems such as Rehametrics physical use motion sensors to record variables such as:
- range of motion
- execution speed
- accuracy
This allows you to:
- objectify the execution of the exerciseobjetivar la ejecución del ejercicio
- detect offsets
- monitor progress
Motion capture transforms subjective clinical observation into quantifiable data.
Visual feedback and correction during the task
The patient receives real-time feedback on their movements through visual cues. This facilitates immediate correction, greater precision, and fewer errors.
Interactive environments that encourage repetition
One of the most important elements is the use of structured interactive activities.
These allow you to:
- set clear goals
- keep the patient’s attention
- break up the monotony
As a result, it is possible to significantly increase the number of repetitions without increasing the perceived effort or boredom.
This is particularly important for patients with poor adherence or cognitive fatigue.
Reducing kinesiophobia through progressive exposure and movement control
Virtual environments not only allow for the implementation of progressive exposure strategies, but also introduce additional relevant elements for patients with kinesiophobia.
First, working in a controlled and predictable environment reduces the perceived threat associated with movement. Virtual tasks are perceived as safer, which makes it easier for participants to engage even in the early stages.
In addition, the ability to adjust parameters such as range of motion, speed, and difficulty allows for precise modulation of the stimulus, tailored to the patient’s tolerance.
Real-time feedback also plays a key role, as it helps to:
- increase the sense of control
- reduce uncertainty
- improve confidence during execution
On the other hand, interactive environments foster a sense of repeated success by allowing users to accomplish achievable tasks from the early stages, which enhances self-efficacy and the willingness to make progress.
Finally, the interactive nature of these activities introduces a particularly important element: the modulation of attention.
In patients with persistent pain, hypervigilance shifts the focus toward pain or bodily sensations, increasing the perception of threat. Virtual tasks, by requiring specific goals, help shift the focus of attention toward the activity.
This contributes to:
- reduce the perception of threat
- reduce pain
- facilitate the continuity of the exercise
Taken together, these elements not only allow for a gradual reintroduction of movement but also facilitate greater exposure to exercise in conditions where the perceived threat is lower, which is key for patients with kinesiophobia.
Occupational rehabilitation in immersive environments
Rehametrics Occupational VR uses virtual reality headsets to simulate:
- activities of daily living
- functional tasks
- ecological contexts
This allows you to:
- train movements with functional significance
- increase patient engagement
- encourage the application of learning to real-life situations
Immersive environments facilitate more context-based and task-oriented training.
Personalized exercise plan
These platforms allow you to modify settings such as:
- range of motion
- processing speed
- required accuracy
- complexity of the task
This allows for continuous adaptation based on:
- patient’s ability
- clinical course
- answer to the exercise
Conclusion
For many patients with persistent musculoskeletal pain, the problem is not a lack of treatment, but rather:
- insufficient physical activity
- the presence of kinesiophobia
- poor workmanship
- and a lack of feedback during the exercise
Addressing these factors requires strategies that enable:
- increase the volume of practice
- improve the quality of movement
- reduce the fear of movement
- and promote adherence
In this context, tools that combine motion capture and virtual environments represent not only a technological innovation but also a way to address common clinical limitations in daily practice.
