5 Ways ErgoBot Leads a Breakthrough in Robotic Hip Rehabilitation for Aging Populations

Robotic hip rehabilitation is transforming care for seniors aged 65+, many of whom suffer from restricted hip internal rotation—an essential movement for turning, walking, dressing, and avoiding falls. In Europe, approximately 35% of seniors aged 65+ experience significant limitations in hip internal rotation. After total hip arthroplasty (THA), rehabilitation protocols often include 12–20 supervised therapy sessions over 6–8 weeks to restore hip function, yet workforce data shows major gaps: the EU has around 611,000 physiotherapists, with wide disparities among countries. Many seniors receive far fewer therapy sessions due to staff shortages, delayed access, or limited capacity in nursing home care. These delays and deficits lead to persistent stiffness, reduced hip internal rotation, poorer balance, and faster loss of independence. This reality underscores why nursing home automation and robotic assisted rehabilitation have become critical paths forward.

The Clinical Need: Internal Rotation Loss in Seniors

Hip internal rotation tends to decline steadily with age. Research shows that older adults typically lose internal rotation ROM (range of motion) and this loss correlates with reduced functional ability, gait issues, and higher fall risk. For example, after THA, study participants in a pilot progressive strengthening and functional retraining program required up to 16 supervised sessions over a 12- to 16-week period to regain improved ROM and internal rotation (among other hip movements).

In post-hip fracture elderly patients (age ≥ 65), mobility decline is measurable 4-6 months after surgery, indicating that inadequate early therapy (including internal rotation work) can result in prolonged functional impairment. (BMC Geriatrics)

The Workforce Challenge: Therapist Shortages in Europe

According to Eurostat, in 2021 there were 611,000 physiotherapists working across the European Union — averaging about 136.7 physiotherapists per 100,000 inhabitants. However, this number is unevenly distributed; some countries have very low ratios (e.g. Romania with ~12.7 per 100k) while others are much higher. (Eurostat News)

In addition, the “Health at a Glance: Europe 2024” report highlights a gap of 1.2 million healthcare professionals (including doctors, nurses, midwives) needed across the EU, which also impacts allied health roles like physiotherapists and occupational therapists. (ERWCPT / OECD)

These shortages mean many seniors cannot access the recommended number of rehabilitation sessions—for internal rotation, gait training, and functional recovery—leading to under-rehabilitation.

How Robotic Hip Rehabilitation Helps

When properly implemented in care settings (especially in robotic assisted nursing home and nursing home automation contexts), robotic hip rehabilitation offers several critical advantages:

• • Targeted internal rotation training from early post-surgery or post-immobilization stages, helping prevent joint contractures and improve hip mechanics.

  • Ability to deliver 12-20+ sessions over 6-8 weeks or more frequently compared to what limited human resources can manage.

  • Integration with robotic assisted Ergotherapy and robotic assisted Occupational therapy, combining range-of-motion work with functional tasks for better carryover.

  • Constant objective measuring of internal rotation, range of motion, strength and patient compliance.

  • Reduced physical burden on therapists and staff, making automation and scalable solutions more feasible.

Implementation in Practice

Facilities adopting these models (robotic assisted rehabilitation, robotic assisted Ergotherapy, robotic assisted Occupational therapy) can embed internal rotation protocols into daily routines. For example:

• Begin internal rotation mobilization early after THA or fracture, respecting surgical precautions.

• Schedule frequent short sessions (e.g. 2-3 times per week in clinic/hybrid) plus home exercise programs.

• Use remote supervision or tele-rehablitation tools for follow-ups, reducing missed sessions.

• Use robotics where possible to replicate high repetition and precise movement in the internal rotation plane.

Conclusion

Robotic hip rehabilitation with a focus on internal rotation is essential for seniors 65+ to maintain mobility, reduce fall risk, and preserve independence. With many European countries facing physiotherapist shortages and many elderly not receiving the recommended 12-20+ therapy sessions over 6-8 weeks (or more for THA), robotic assisted rehabilitation in nursing home automation settings becomes not just an innovation but a necessity. Combining robotic assisted Ergotherapy and robotic assisted Occupational therapy into care pathways amplifies outcomes while addressing workforce constraints. For senior care providers, investing in these solutions means delivering better mobility, safer care, and more sustainable health outcomes.
