Friedreich's Ataxia
The mFARS annual exam snapshot plus every fall, palpitation, and Skyclarys morning in between.
The mFARS is the validated instrument that carried Skyclarys through the MOXIe trial, and it stays the backbone of every FA study. It scores a neurological exam once a year. Forma adds the between-visit stream that a yearly exam can't hold: daily, structured, patient-reported data on gait, falls, dexterity, cardiac symptoms, and fatigue. Keep the mFARS. Add the days it doesn't see, and show whether the drug is changing patients' actual lives.

How it works
15 seconds of speech. 25 data points.
Forma keeps the mFARS and turns each FA patient into a continuous data stream around it. By voice or text, patients and caregivers log gait stability and assistive device use, falls with circumstances and injury, upper limb coordination during daily tasks, speech clarity, cardiac symptoms, fatigue severity, and Skyclarys adherence, all in under a minute. No forms, no recall bias. The result is a structured, longitudinal dataset across every FA domain: daily mobility trajectories mapped to assistive device transitions, fall frequency correlated with fatigue and environment, fine motor decline tracked through real tasks like handwriting and phone use, and Skyclarys treatment response visible across weeks rather than inferred from a single annual mFARS score.

From data to insights
What the data reveals
Daily voice logs compound into actionable insights, for patients managing their condition and for researchers running studies.
For Patients
Is Skyclarys actually doing anything for me?
Since starting Skyclarys 14 weeks ago, your daily gait distance has increased from averaging 800 to 1,200 steps before needing the wheelchair. Falls dropped from 6/month to 3/month. Your fatigue scores haven't changed (still averaging 6.8/10), but your mobility window (time on crutches before switching to the chair) grew from 2.5 to 4 hours. LFTs from last week are normal. This is the between-visit picture your annual mFARS can't show on its own.
Gait distance on Skyclarys
Why do I fall more at school than at home?
Your school falls happen 3x more often than home falls. The pattern: 80% occur during class transitions in crowded hallways, usually periods 3-5 when fatigue is highest. Home falls cluster around the bathroom. On days you use the wheelchair for transitions after 2nd period, you have zero hallway falls. Your PT might want to adjust the school mobility plan.
Falls by location
Is my speech getting worse?
Your speech clarity is stable overall, but there's a clear fatigue pattern. Morning logs: friends understand you 90% of the time. After 3 PM: that drops to 60%. On days with fatigue scores above 7, afternoon speech clarity drops another 15%. The trend over 3 months is flat, not declining. Your dysarthria isn't progressing, it's fatigue-dependent.
Speech clarity by time of day
Summarize my semester for the neurologist.
Gait: crutches for 4 hours/day, wheelchair remainder. Improving since Skyclarys (was 2.5 hours in September). Falls: 3/month (down from 6 pre-Skyclarys). Hallway transitions are the main trigger. Upper limb: handwriting declining, switched to laptop for essays. Typing stable. Speech: mild dysarthria, fatigue-dependent, not progressing. Cardiac: 4 brief palpitation episodes, all during PE. Skyclarys: 93% adherent, LFTs normal x3. Scoliosis: stable, brace compliant. Fatigue: 6.8/10 average, worst after gym and 5th period. Pair this with the next mFARS.
For Researchers
Does Skyclarys improve daily function beyond what mFARS captures?
Across 34 FA patients on Skyclarys, daily mobility composite scores improved by 18% at 6 months, while annual mFARS change was 1.8 points (below the 3-point MCID proposed for trials). Daily fall rate declined 42% (mean 5.1 to 2.9/month). The two views answer different questions: the mFARS captures the neurological exam, and the daily stream captures how that translates into function between exams. 71% of patients showing daily functional improvement fell short of the mFARS responder threshold at annual assessment, so the daily data documents benefit the yearly score alone would miss.
Daily function vs. mFARS
Trend
What is the real-world mobility trajectory between annual visits?
Daily logging reveals that assistive device transitions are not gradual. 74% of patients show a discrete step-down event (e.g., crutches to wheelchair full-time) over a 2-3 week window, typically triggered by a fall cluster or illness. Monthly trajectory analysis detects these transitions 5.1 months before they would surface on the next annual mFARS. Pre-transition fall rate acceleration (>2 falls/week for 3+ weeks) is the strongest early signal, with 79% sensitivity.

Trend
What cardiac symptoms occur between echocardiograms?
Palpitation episodes average 3.8/month across our cohort, and 82% go unreported at cardiology visits. Exertional dyspnea is logged on 29% of patient-days but attributed by patients to 'normal FA tiredness.' Daily cardiac logging detected symptom patterns prompting early cardiology referral in 4 of 34 patients (12%), with one new arrhythmia diagnosis. Patients with >6 palpitation episodes/month had 2.8x the rate of echocardiographic progression at 12-month follow-up.
Unreported cardiac symptoms
Trend
Can daily data support Skyclarys HTA and label expansion submissions?
Canadian regulators explicitly flagged evidence gaps for Skyclarys: no data on advanced disease, non-neurologic manifestations, or long-term efficacy. Our daily dataset addresses all three, capturing wheelchair-dependent patients (N=11), cardiac and fatigue domains, and 12+ month trajectories. Alongside the annual mFARS, a daily fall-rate endpoint achieves Cohen's d=0.71 for Skyclarys responders (vs. 0.28 for the annual mFARS alone). A simulated HTA dossier pairing the mFARS with daily functional data meets CADTH's real-world evidence threshold for supplemental submission. The daily stream is structured for clinical-trial submission and yours to export, with no lock-in.

11 days of raw patient data
The day-by-day voice log behind the insights above, and the detail that periodic check-ins can't capture.
First day back from spring break. Made it through 1st and 2nd period on crutches, then switched to the chair. Hands were shaky in art class, couldn't hold the brush steady. Tired by lunch.
Someone bumped me in the hallway between 3rd and 4th period. Crutch slipped and I went down. Knee is scraped. The aide helped me up. Really embarrassing, everyone was staring. Used the chair the rest of the day.
Took Skyclarys before breakfast like always. Felt nauseous until about 10. Mom says I should try taking it earlier. Knee still sore from Tuesday. PT after school, balance exercises on the mat. Exhausting but my PT says my trunk control is better than last month.
Chill day at home. Played video games, controller is getting harder to use, keep hitting wrong buttons. Tried to help mom cook dinner, dropped a glass. She wasn't mad but I was frustrated. Speech was fine today.
Good morning. Made it through 3 periods on crutches, that's one more than last week. Heart felt fluttery during PE, lasted maybe 10 minutes. Sat out the rest of class. Told the teacher it was nothing but it scared me a little.
Got blood drawn after school for liver tests. Hate needles. School was okay, used the chair for hallway transitions after 2nd period like my PT suggested. Zero falls this week so far. Typing my history essay was slow but I got it done.
Friend's birthday party. Dad drove me. Used the wheelchair the whole time, didn't want to deal with crutches. My speech was bad by 9 PM, everyone kept asking me to repeat stuff. Tired but glad I went.
Was just sitting watching TV and my heart started racing. Lasted about 20 minutes. Mom almost called the cardiologist but it stopped. Felt weird after. Didn't do much the rest of the day. Scoliosis brace is bugging me.
Mom got the liver test results, all normal. Doctor says keep going with Skyclarys. School was actually good today. Made it through almost 4 periods on crutches before switching to the chair. That's my best since starting the drug. PT noticed too.
10 days no falls! My PT said the new hallway plan is working: chair for transitions, crutches in class. Handwriting is still bad but I'm getting faster on the laptop. Mom cried when I told her about the no-falls streak. I think the Skyclarys might actually be helping.
New week. Energy was better today, only really crashed after 5th period. Speech was clear enough for my presentation in English. Teacher said she could understand everything. Still using the hybrid plan at school. Neuro appointment next month, mom's printing out my logs.
Key insight
Over three weeks, Mia's daily logs fill in the days between mFARS exams: the hallway fall on day 2 that led to a mobility plan change (chair for transitions, crutches in class), the cardiac palpitation on day 14 that would have gone unreported until her next echo, and the treatment response arc that took her from 2 periods on crutches to nearly 4. That's a functional gain a single annual exam can't resolve, and exactly the evidence Skyclarys needs to demonstrate real-world benefit. By day 19, she hit 10 consecutive fall-free days, a milestone her neurologist can pair with the next mFARS to justify continued treatment and that HTA submissions need to prove the drug is changing patients' daily lives.
