Yes, absolutely. Here's a realistic breakdown:
Is This Study Feasible?
The Core Idea — YES, It's Very Doable
Chair-based exercise + cognitive training in community-dwelling older adults is:
- Low-cost (no expensive equipment except HHD)
- Low-risk for participants
- Practically executable in a community hall, temple, or senior center
- Well-supported by existing literature (your own references confirm this)
Issue-by-Issue Feasibility
🟢 Easy to Fix (Before Resubmission)
| Problem | How to Fix |
|---|
| Typos (Primay, Cool up, bductors) | Simple proofreading — 30 minutes |
| Incomplete references 12 & 14 | Look up on PubMed — 1 hour |
| Vancouver format errors | Reformat author names — 1 hour |
| Declaration title missing | Fill in the blank — 5 minutes |
| Exclusion criteria mismatch | Copy exact list to proforma — 15 minutes |
🟠 Moderate Effort (Needs Thinking, But Doable)
Fix the duration inconsistency
- Decide: Is the intervention 2 weeks or 4 weeks?
- For a UG BPT project with 4-month total timeline, 4 weeks of intervention is realistic
- Then update all three documents (proposal, PIS, Kannada version) to say the same thing
- Time needed: 1 day
Define "short term"
- Simply state in the methodology: "Short term is defined as a [4]-week intervention period"
- One sentence addition
Specify statistical tests
- Normality: Shapiro-Wilk (n=30 is small)
- If normal: Paired t-test (pre vs post, within group)
- If not normal: Wilcoxon signed-rank test
- This is standard for a pre-post pilot study
- Time needed: 1–2 hours with supervisor guidance
Fix IPAQ-SF dual use
- Use IPAQ-SF only for screening (to confirm low-to-moderate activity level at baseline)
- Remove it from the outcome measures list
- Your actual outcomes are HHD, FIST, MoCA, Stroop — that's sufficient
- Time needed: 1 hour to revise the document
Add adverse event plan
- Add one short paragraph: "In the event of any adverse event (fall, chest pain, dizziness), the session will be stopped immediately. First aid will be available on site. Participant will be referred to the nearest medical facility. The event will be reported to the CEC within 24 hours."
- Time needed: 30 minutes
🔴 Requires More Work (But Still Achievable for a UG Project)
The "randomized" design problem
This is the most important issue. You have two realistic options:
Option A — Keep randomization, simplify it
- Recruit 30 participants, randomize into:
- Group 1 (n=15): Chair exercise + cognitive training
- Group 2 (n=15): Chair exercise only (active control)
- This makes it a genuine pilot RCT
- Add one paragraph describing randomization (e.g., sealed envelope method)
- Pros: Scientifically stronger, publishable
- Cons: Needs 30 participants across two groups, slightly more complex
Option B — Change design to pre-post single group
- Remove the word "randomized"
- Call it: "Single-group experimental pre-test post-test pilot study"
- Much simpler, honest, and still publishable as a pilot
- Pros: Easier to execute, suitable for UG project, no randomization needed
- Cons: Lower evidence level, but acceptable for a BPT project
Recommendation for a BPT 7th semester student: Choose Option B. It is honest, feasible within 4 months, and still publishable in a physiotherapy journal.
Sample size justification
- For Option B (single group pre-post), cite a similar study showing effect on MoCA or HHD in older adults with exercise
- Example: Liao et al. (your reference 5) showed improvements in cognitive function with chair-based exercise
- Ask your supervisor to help extract the effect size from that paper and re-run G*Power
- Time needed: 2–3 hours with supervisor
FIST justification for healthy older adults
- Add one sentence acknowledging FIST was originally validated in stroke but has since been used in healthy aging populations
- Alternatively, replace with Functional Reach Test or Timed Up and Go — both are well-validated in community-dwelling elderly
- However, since your intervention is chair-based, FIST actually makes sense contextually — just add a citation supporting its use in non-stroke populations
Realistic Timeline to Resubmit
| Week | Task |
|---|
| Week 1 | Fix all typos, references, formatting |
| Week 1 | Decide on Option A or B design |
| Week 2 | Revise methodology section (duration, design, statistics) |
| Week 2 | Add adverse event plan, fix IPAQ issue |
| Week 3 | Get supervisor review and signature |
| Week 4 | Resubmit to CEC |
Bottom Line
Yes, this study is entirely possible. The concept is solid. The hard work of designing the intervention protocol (the circuit tables) is already done well. What needs fixing is mostly documentation clarity and one key design decision about the control group.
The most important single action: meet with your supervisor Dr. Anjali Suresh and decide on Option A vs Option B, then everything else flows from that decision.
