Outcome Measures

Primary Outcomes (1)

  • Change in Socket comfort score

    Patient-reported socket comfort

    Up to 6 months

Secondary Outcomes (4)

  • Change in EQ-5D-5L

    Up to 6 months

  • Change in Locomotor Capabilities Index (LCI-5)

    Up to 6 months

Study Arms (1)

Confidence socket

EXPERIMENTAL

Participants to receive a confidence socket system

Device: Amparo confidence socket

Interventions

Confidence socket involves thermoplastic material being moulded onto the patient's residual limb and a socket is produced in a single session. The socket can be remoulded to adjust to changes in residual limb volume.

Eligibility Criteria

Age18 Years+

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Over the age of 18
  • New transtibial amputation within the last 6 months
  • Deemed ready to cast for a prosthesis by the clinical team as per usual care at the prosthetic centre
  • Able to understand written English and provide informed consent

You may not qualify if:

  • Participants under the age of 18
  • Participants with an ankle disarticulation, Knee disarticulation or transfemoral amputation
  • Body mass \> 125 kg with a distal circumference of 23-34 cm (small socket)
  • Body mass \> 150 kg with a distal circumference of 30-45 cm (large socket)
  • Residual limb longer than 27 cm
  • Severe upper limb dysfunction (due to strength requirements to don the liner)
  • Severe visual requirements (that would restrict the person's ability to monitor their residual limb)
  • Contraindication to be fit for a prosthetic socket
  • Recent cerebrovascular event (i.e., stroke, haemorrhage, brain injury)
  • Disease affecting their memory
  • Unwilling to trial the confidence socket system
  • Unable to tolerate wearing a prosthetic liner due to excess sweating/ allergic reaction or other reasons
