After a burn injury, due to hypertrophic scar formation, shoulder joint contracture, pain, and limited range of motion are common problems in individuals with upper body burns. However, beyond scars, posture—especially positions maintained over long periods—also plays a critical role in shoulder function (see previous article: Posture in Burn Shoulder Rehabilitation: Why Range of Motion Remains Limited Even After Scar Improvement).
These everyday postures are often not found in large or extreme movements (such as overhead reaching), but rather in small daily habits. They are usually subtle, low-intensity, and appear harmless or convenient, making them easy to overlook. However, over time, they may gradually increase the load on muscles and soft tissues, offsetting or reducing the benefits of rehabilitation exercises. This creates a “tug-of-war” between outcomes achieved in therapy and those shaped by daily life in burn shoulder rehabilitation.
Therefore, this article summarizes postures and usage habits commonly observed yet often overlooked in clinical practice to help therapists:
Identify risk factors affecting shoulder function from a daily-life perspective.
Evaluate compensatory strategies after burns from a functional and real-life perspective.
Ultimately, this allows a clearer understanding of how daily behaviors influence the outcomes of burn shoulder rehabilitation.
Which Daily Postures and Habits May Affect Burn Shoulder Rehabilitation and Shoulder Function?
These postures and habits typically do not cause immediate pain or obvious limitations. Instead, they influence shoulder movement and function gradually through low-intensity, long-term accumulation. They can be broadly divided into two categories:
Postural Habits
These refer to body positions that are maintained for long periods, often without conscious awareness. Common situations in which burn patients develop postural habits affecting the shoulder include:
Posture affecting joint shoulder | Common everyday situations | Potential impact |
Forward Shoulder or Rounded Shoulder |
| Changes in the relative alignment of the neck, scapula, and shoulder joint, affecting muscle force transmission. |
Forward Head Posture | ||
Preference for One-Sided Support |
| Asymmetrical loading between left and right shoulders. |
Lack of Arm Support (Arm Hanging or Unsupported) |
| Fatigue and overuse of shoulder and upper limb muscles. |
Burn patients may develop a habit of using these postures due to discomfort or movement limitations caused by wounds or scars (not necessarily only in the situations listed above), or they may have already had these postural habits, but the presence of wounds and scars increases how frequently they are used. When time spent in non-neutral anatomical positions increases, the risk of muscle imbalance also increases.
Usage Habits
These refer to repeated movement patterns during daily functional activities, often developed to complete tasks.
For burn patients, many usage habits are compensatory strategies developed due to movement limitations. In the short term, they are often reasonable and necessary, and may even be essential for maintaining daily function. However, because progress in motor function may not be ideal or comprehensive (especially when the burn area is extensive), compensatory usage patterns may become limited in variety or overly reliant on specific dominant body parts. This can gradually lead to rigid joint movement patterns, muscle imbalances, or secondary issues such as pain.
Focusing on the shoulder joint, the following examples illustrate the development of compensatory movement patterns in individuals with burn injuries:
When one shoulder or upper limb is limited, the individual compensates using the other side or both shoulders, leading to overuse of shoulder muscles. (e.g., using only the left hand for daily tasks when the right hand is injured; or controlling a prosthesis using shoulder movements)
When shoulder movement is limited, other body parts compensate, or individuals adopt energy-saving strategies with reduced shoulder motion. This decreases shoulder activity (even immobilization) while overloading other areas. (e.g., leaning forward or sideways to reach objects, using the abdomen to assist lifting, drinking only with a straw, bringing the mouth to the bowl instead of using utensils, removing a shirt by swinging after unbuttoning)
It is important to note that although these habits are discussed in relation to the shoulder, the body functions as an interconnected system. Changes may also occur in the neck, upper limbs, pelvis, or lower limbs. For example, consistently using only the left hand may lead to increased tension and secondary pain in the left side of the trunk.
Should Compensatory Strategies Be Modified in Burn Shoulder Rehabilitation?
Compensation does not necessarily mean “incorrect movement.” Whether it should be modified depends not only on the movement itself, but also on the context in which it occurs.
Clarifying Functional Needs Behind Compensation
The first question to ask is:
What function is this movement trying to achieve?
Why was this method chosen? (Is it due to movement limitation, convenience, efficiency, etc.?)
For therapists, a further question is:
Are there alternative ways to achieve the same function given the patient’s current abilities?
Some compensations are unavoidable in order to maintain basic daily function or quality of life—especially when there is no caregiver support or when limitations are significant. In such cases, compensation should not be immediately eliminated, but instead they should be understood. However, as conditions change, these strategies should be regularly re-evaluated.
Evaluating the Load and Cost of Compensation
After understanding functional needs, the next step is to assess long-term impact:
Does it place the shoulder in a suboptimal or overloaded position for extended periods?
Does it restrict movement patterns or limit the range available for training?
Does it increase fatigue or secondary pain in the shoulder or other areas?
If the answer to any of these is “yes,” the next key question is whether the patient is concerned or affected by it. Only when the patient recognizes its impact does modifying compensation become meaningful and effective.
When Compensation Is Unavoidable, What Can Therapists Do?
Some compensation is inevitable in daily life. However, if therapists can anticipate its impact early, they can intervene strategically rather than reactively.
The focus is not necessarily on eliminating compensation, but on:
Establish stronger foundational capacities (muscle strength, endurance, and motor control) at an early stage to increase the range and tolerance of compensatory strategies.
Modify movement patterns to better align with energy conservation and biomechanical efficiency.
Optimize the usage environment and postural conditions to reduce unnecessary physical load.
Provide feasible relaxation and recovery strategies to extend the duration of functional tolerance.
The ultimate goal is not to eliminate compensation, but to reduce its “cost” and delay its negative impact, making it more sustainable over time.
How Do Daily Posture and Habits Affect Shoulder Function in Burn Shoulder Rehabilitation?
The effectiveness of shoulder rehabilitation following burn injuries depends not only on the treatment interventions themselves, but is also strongly influenced by daily posture and usage habits.
These seemingly minor behaviors may, over time, increase the load on muscles and soft tissues and alter movement patterns, potentially offsetting the gains achieved through rehabilitation (for example, strengthening the scapular stabilizers during therapy while continuing to perform daily activities with a rounded-shoulder posture).
Therefore, in addition to designing intervention strategies, therapists must understand how individuals use their bodies in daily life and make appropriate adjustments and trade-offs between functional demands and long-term physical burden.
