IntelliCane: Instrumented cane for diagnosis and evaluation of gait behavior in individuals with mobility issues.

IntelliCaneTM: An Instrumented cane for the objective evaluation of gait characteristics in individuals with mobility issues.

Addressed Need

Physical therapists perform functional gait assessments to monitor the progress of rehabilitation therapy for individuals with mobility issues. A significant component of this assessment is the assignment of subjective scores based on observation of the individual while performing a series of mobility tasks. The disadvantages of this approach are: 

  • low degree of intra-rater and inter-rater consistency
  • non-objective measures of timing and cane placement
  • gait assessments typically limited to within a setting

Technology Description

Vanderbilt engineers have developed a gait assessment tool utilizing a modified standard walking cane  with an embedded instrumented system to provide objective and quantitative data.  The associated software system can analyze the generated data to provide measures of variables such as timing and speed of cane placement, angular acceleration of the cane, and amounts of weight borne by the cane.

This system is designed to assist physical therapists:

  • collection of objective data during gait analysis,
  • facilitate appropriate assistive gait device prescription,
  • provide patients and therapists feedback during gait training, and
  • reduce wrist and shoulder injuries with cane usage.

In addition to this, with the data obtained from this cane, automated gait analysis and gait pattern classification can be performed to understand a patient’s walking performance.

Technology Development Status

  • Lab prototype fabricated
