Low Back Pain at Follow-Through in a Desk-Based Golfer
Marcus is a 47-year-old right-handed amateur (14 handicap) who plays twice weekly and hits 120 range balls on a mat three times weekly. He works nine hours a day at a desk and reports sharp right-sided low-back pain that begins at follow-through and lingers after 18 holes; pain is 4/10 during play and 2/10 at rest, with no numbness, night pain, or prior back surgery. Screening shows right hip internal rotation 10° versus 28° on the left, right ankle dorsiflexion 7 cm versus 11 cm, and thoracic rotation 32° right versus 41° left. His overhead squat shows heels rising and arms falling forward. Swing video shows early extension and a reverse spine angle at the top of the backswing. He wants to keep playing weekly and asks whether he should stretch his back more.
1. Using a kinetic-chain lens, explain the most likely mechanical contributors to his low-back pain at follow-through. Do not diagnose; identify the chain of compensation and the tissue load.

The likely chain is not a "tight back" but limited rotation below and above the lumbar spine. With right hip internal rotation at 10° versus 28° on the left, the pelvis cannot clear out of the way during the downswing and follow-through. To get the club to the ball and then to finish, he adds lumbar rotation and extension-visible as early extension and reverse spine angle. Limited right ankle dorsiflexion (7 vs 11 cm) reduces his ability to load the right leg and shifts demand up the chain; the overhead squat shows the same ankle and hip restriction. The repeated end-range extension and rotation under load-360 range balls plus play-concentrates stress on the right lumbar posterior elements and paraspinals. Pain at follow-through fits that compression and rotation load. This is a mechanical hypothesis, not a diagnosis; persistent or progressive symptoms need medical review.
2. Which assessment finding would you address first, and why? Include one re-test you would use to judge change.

Address right hip internal rotation and ankle dorsiflexion first, because they are upstream constraints that can let the lumbar spine do less. A reasonable priority is hip internal rotation mobility plus glute and hip control, with ankle dorsiflexion drills before swings. Re-test right hip internal rotation in supine and overhead-squat depth after two weeks. Do not chase thoracic rotation first: his thoracic rotation is better than his hip rotation, and adding more thoracic range without hip range may simply let him find more lumbar extension. If pain increases, stop and refer.
3. He asks whether static hamstring and low-back stretching should be his main intervention. How do you respond, and what would you change in his weekly swing volume in the first two weeks?
Read the worked answer
Static low-back stretching is unlikely to be the main fix and may temporarily reduce stiffness without changing the constraint. Use short-duration mobility for hip internal rotation and ankle dorsiflexion, then activate hip extensors and abductors, then integrate with a half-kneeling or split-stance rotational drill. Cut range-ball volume from 120 balls three times weekly to about 40–50 quality balls twice weekly for two weeks, reduce full-swing reps on mats, and keep play to one round while symptoms settle. Reassess pain during follow-through and right hip internal rotation. If pain is unchanged or worsening, refer.
