Summary:

• Italian trial compares standard and technology-assisted rehab in 21 men with below-knee amputation

• D-Wall training showed no detectable functional edge in this small sample

• Higher self-efficacy linked to less anxiety, depression, and body image distress

• Researchers recommend early psychological assessment and tailored support during rehab

• Study limited by all-male, single-center design and no follow-up after discharge

Learning to live with a prosthetic leg means relearning balance, gait, and daily routines, along with adapting to a transformed body. While conventional rehabilitation still exists, rehab programs now increasingly incorporate technology, such as virtual reality systems and motion-based biofeedback. However, authors of a 2026 study published in Frontiers in Rehabilitation Sciences point out that evidence on whether these tools provide benefits beyond traditional rehabilitation remains limited. Their research offers an initial, small-scale look at this issue.

Traditional vs. high-tech rehab  

The clinical trial was conducted at the Istituti Clinici Scientifici Maugeri in Montescano, Italy, involving 21 men with an average age of around 62. All participants had a below-knee amputation caused by either type 2 diabetes or vascular disease. They began a three-week inpatient rehabilitation program about two to three months post-surgery, after the surgical wound had healed.

The study participants were randomly divided: 11 received traditional rehab, while 10 underwent a combined program that incorporated technology. Everyone used the same standardized prosthetic setup and participated in the center’s multidisciplinary program, which included sessions with physiotherapists, physiatrists, psychologists, and nutritionists.

Training time lasted 90 minutes daily, five days a week. In both groups, 60 minutes focused on hands-on physiotherapy targeting joint mobility, strength, balance, posture, and gait. But the remaining 30 minutes differed: the traditional group received clinical supervision or supportive consultations, whereas the technology group trained on the D-Wall (TecnoBody), an interactive digital wall equipped with a 3D camera and motion sensors to monitor posture, balance, gait initiation, and spatial orientation. The system provides real-time feedback via an on-screen avatar and graphics, without markers or wearable sensors, and is classified as non-immersive virtual reality with biofeedback.

What improved for everyone  

Across the sample, prosthetic mobility (evaluated with the Amputee Mobility Predictor), independence in daily activities (measured by the Barthel Index), and overall functional independence (assessed through the Functional Independence Measure) all showed improvements from admission to discharge. These improvements were consistent across different groups.

On the mobility scale, which ranges from 0 to 42, average scores increased from about 12 to roughly 27. The researchers interpreted this overall trend as an indication that the initial weeks of intensive training are an optimal period for functional recovery and that traditional rehabilitation provides a strong foundation.

Other measures, including fall risk, self-reported quality of life, anxiety, and distress about body image, did not change significantly over the three weeks, though depressive symptoms showed a downward trend.

The emotional side of adjustment  

The study also provided more details on the psychological side of recovery. At admission, researchers assessed acceptance of the health condition, perceived support from family and friends, and self-efficacy, which is confidence in managing the condition and following the treatment plan. These early assessments aligned with rehabilitation progress. Individuals with better self-efficacy generally experienced fewer depressive symptoms and less anxiety, were less bothered by their body image, and achieved higher scores in prosthetic mobility.

Within groups, patterns varied. For those in traditional rehab, decreases in anxiety align with better self-rated quality of life. For those who trained on the D-Wall, improved body image correlated with lower anxiety, and lower depression was associated with increased independence. The researchers suggest that real-time visual feedback may influence body perception and mastery, while a structured setting may promote emotional stability.

Study limitations  

It’s important to keep in mind that the results come with limitations. All 21 participants were men with limb loss due to vascular issues or diabetes, so the findings may not apply to women, younger individuals, those with traumatic limb loss, or upper limb loss. The authors highlight that psychological factors, especially regarding body image and social interaction, could differ across these groups.

Additional limitations include recruiting participants from only one rehab center, following up only until discharge, relying on self-report questionnaires, and lacking blinding for both participants and clinicians. While the group assignment was based on a pre-generated list, the study did not employ formal allocation concealment, a method that withholds a participant’s upcoming group allocation from enrolling staff until the assignment is made. This process helps prevent selection bias and maintains randomization integrity.

Furthermore, since the trial concluded at inpatient rehabilitation, it provides no insights into how adjustment continues once individuals return home.

What this means for people undergoing rehabilitation   

The improvements observed in this study occurred during the rehabilitation program, which used both traditional and technological methods. When choosing a program, it may be more important to focus on whether it is intensive, structured, and multidisciplinary rather than on the inclusion of a specific device.

Regarding the psychological findings, the researchers recommend assessing psychological factors such as self-efficacy, acceptance, and body image early in the process and providing customized support. Caregivers and family members can assist by fostering open conversations about these issues.

Regarding technology, this study suggests that tools like the D-Wall could supplement conventional therapy, though benefits remain unproven. If you are considering your rehabilitation choices, consider asking your care team:

• How will progress be monitored beyond walking ability?

• Is psychological support integrated into the program, and when does it start?

• If technology is included, what purpose does it serve, such as providing feedback, motivation, or additional practice time?
