DPT Therapeutic Interventions & Techniques 5

Question 1

During eccentric muscle training, which physiological advantage makes it superior to concentric training for tendon rehabilitation?

Accepted Answer

Higher mechanical tension promoting collagen synthesis in the tendon

Answer

Eccentric loading generates higher tensile forces within the tendon, which stimulates tenocytes to produce collagen and remodel the tendon's structural integrity.

Question 2

A therapist applies continuous ultrasound at 1 MHz with 1.5 W/cm² for 8 minutes over scar tissue. The PRIMARY therapeutic goal of these parameters is:

Accepted Answer

Tissue heating to increase extensibility and promote remodeling

Answer

Continuous ultrasound at these parameters produces significant thermal effects, elevating tissue temperature to improve collagen extensibility and promote remodeling of scar tissue.

Question 3

Which manual therapy intervention is BEST supported by evidence for reducing pain and improving function in patients with hip osteoarthritis?

Accepted Answer

Long-axis distraction and anterior-posterior glides of the hip

Answer

Long-axis distraction and AP glides of the hip directly address intra-articular restrictions and capsular tightness, which is well-supported in clinical guidelines for hip OA.

Question 4

A patient with hemiplegia is being treated using the Bobath (NDT) approach. The concept of 'key points of control' refers to:

Accepted Answer

Proximal body segments used to influence distal tone and movement patterns

Answer

NDT key points of control are proximal body regions (e.g., shoulder girdle, pelvis) through which the therapist can modulate tone and facilitate normal movement distally.

Question 5

Which parameter adjustment would INCREASE the depth of tissue heating when using shortwave diathermy?

Accepted Answer

Increasing pad separation in capacitive application

Answer

In capacitive shortwave diathermy, increasing electrode separation concentrates the electric field in deeper tissues relative to subcutaneous fat, improving depth of heating.
