Articulate Labs

AL’s first device, KneeStim, is a light, low-profile device that uses neuromuscular electrical stimulation (NMES) to dynamically stimulate quadriceps muscles in sync with regular activity, accelerating rehabilitation by strengthening and training muscle with each step. KneeStim’s unique mix of AI, motion-tracking hardware, and patented joint modeling OS enables rapid gait and treatment personalization. Collected physiologic data is used to optimize rehab, track compliance, and enable recurring reimbursement. Competitors’ devices do not adapt to movement and can only be used while stationary, leading to reduced efficacy and poor compliance.

15M in the US seeking solutions for knee pain and dysfunction + 1M recovering from knee surgery  ~$10B knee treatment TAM. Poor quadriceps muscle strength correlates with pain, poor mobility, and lower quality of life, creating $3B in avoidable healthcare spend. Physical therapy is effective, but <30% of patients attend all prescribed sessions or remain compliant with their home-based regimens. COVID-19 has driven physical therapy cancellations and no-shows up by 20% and delayed ~10k knee procedures per lockdown week, creating more need for cost- and time-efficient, remote, trackable rehab.
