About this study
Official title: Effects of Targeted Isometric and Isotonic Hand Strengthening on Hand Function, Dexterity, Grip Strength and Grip Endurance in Competitive Female Badminton Athletes
This randomized clinical trial aims to determine the effects of targeted isometric and isotonic hand strengthening exercises on hand function, dexterity, grip strength and grip endurance in competitive female badminton athletes aged 18-30 years. Participants will be randomly allocated into two groups receiving either isometric or isotonic hand strengthening exercise programs performed three times per week for six weeks. Outcome measures will be assessed at baseline, 3rd week and 6th week using Michigan Hand Outcomes Questionnaire (MHQ), Purdue Pegboard Test or Nine-Hole Peg Test, Hand Dynamometer Test and Sustained Grip Test.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Isometric hand strengthening programOther
Participants in this group will receive a structured targeted isometric hand strengthening program performed three sessions per week for six weeks
Isotonic hand strengthening programOther
Participants in this group will receive a structured isotonic hand strengthening program performed three sessions per week for six weeks
| Study group | Role | What they receive |
|---|---|---|
| Isometric Hand Strengthening Group | Experimental | Participants in this group will receive a structured targeted isometric hand strengthening program performed three sessions per week for six weeks including:
Palm Press Hold Fingertip Pinch Hold Tip-to-Tip Finger Press Finger Abduction Hold Ball Grip Hold Each exercise will be performed in 3 sets with progressive hold durations ranging from 5 to 20 seconds across the intervention period. Receives: Other: Isometric hand strengthening program |
| Isotonic Hand Strengthening Group | Active comparator | Participants in this group will receive a structured isotonic hand strengthening program performed three sessions per week for six weeks including:
Stress Ball Squeeze Rubber Band Finger Extension Putty Squeeze Towel Twist Finger Spread Exercises Exercises will be performed in 3 sets of 10-15 repetitions with progressive training duration ranging from 10 to 25 minutes per session. Receives: Other: Isotonic hand strengthening program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hand Dexterity
Hand dexterity will be assessed using the Purdue Pegboard Test / Nine-Hole Peg Test to evaluate fine motor coordination and manual dexterity required for sport-specific hand movements.
Measured: Baseline, Week 3, Week 6
Grip Strength
Grip strength will be measured using a calibrated hand dynamometer to assess maximal voluntary isometric contraction of the dominant hand.
Measured: Baseline, Week 3, Week 6
Grip Endurance
Grip endurance will be assessed using the Sustained Grip Strength Test by measuring the duration for which participants can maintain 50% of their maximal voluntary contraction.
Measured: Baseline, Week 3, Week 6

Questions about this trial
What is this clinical trial studying?
A study testing Isometric hand strengthening program and Isotonic hand strengthening program in people with Athletic Performance and Injury Risk, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 27 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Danish Hassan, PhD (+92 345 7946009 ext. +923457946009, danish.hassan009@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hand Dexterity (time frame: Baseline, Week 3, Week 6). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07438522, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
