Sphygmomanometer as biofeedback in acute anterior cruciate ligament reconstruction rehabilitation: A cost‑effective technique
Quadriceps dysfunction following anterior cruciate ligament reconstruction (ACLR) is a common threat to any sports rehabilitation. Even though the role of biofeedback (BFB) and neuromuscular electrical stimulation has been in use to preserve the quadriceps in the acute phase of ACLR, this paper focuses on retraining the same using a sphygmomanometer as pressure BFB. A 25‑year‑old male collegiate with an isolated tear of ACL was followed up from immediate postoperative period to the outpatient care services for 3 months. The isometric quadriceps pressure difference and heel height difference were measured initially and reevaluated following the intervention. Relearning of impaired quadriceps following an ACLR depends on the response, and so the accurate dose‑response in the form of pressure BFB using sphygmomanometer reduces the financial constraints of a sophisticated BFB unit. It provides an easy understanding of the quality and the magnitude of the exercise.
